1.0 SUMMARY
This technical report (―Report‖) was prepared to provide a National Instrument 43-101 (―NI 43-
101‖) compliant Technical Report with respect to the Mineral Resource Estimate of the gold and
copper mineralization contained in the Gabbs gold-copper property located in the Fairplay
Mining District, Nye County, Nevada, USA. The mineralization of interest is contained within
four prospects namely the Sullivan, Lucky Strike, Gold Ledge and Car Body deposits (the
―Gabbs Property‖ of the ―Gabbs Project‖). St. Vincent Minerals US Inc., a subsidiary of St.
Vincent Minerals Inc. (―St. Vincent‖ or the ―Company‖), is the owner of 100% interest in the
Gabbs Property pursuant to a purchase and sale agreement dated October 29, 2010.
This report was prepared by P&E Mining Consultants Inc. (―P&E‖) at the request of Mr. Brian
Gavin, the chief executive officer of St. Vincent, which is a Toronto, Ontario based resource
company.
1.1 PROPERTY DESCRIPTION AND OWNERSHIP
The Gabbs Property is located in the Fairplay Mining District, on the southwest flank of the
Paradise Range, about 9 km (5.6 mi) south-southwest of the town of Gabbs, Nye County
Nevada. It is centred at UTM 4,292,900N, 417,730 E.
Access to the property is via Highway 361, southwest from Gabbs to Pole Line Rd, then 3.5 km
(2.2 mi) south to the centre of the property.
The Property is situated in an area of dry rolling hills bounded on the west by the Gabbs Valley
and on the east by the northeast trending Paradise Range. Surface elevations for the project area
range from 1,395 metres amsl (4,578 feet) on the northwest corner of the claim block, to
1,770 metres amsl (5,800 feet) on the southeast edge of the property. Vegetation is sparse, with
light coverage by various grasses and low shrubs.
The Gabbs Property consists of 355 unpatented lode claims and 1 patented lode claim which
constitute a 28 km2 (10.8 mi
2) contiguous claim block. The Gabbs claims are held as collateral
through security agreements between St. Vincent Minerals US Inc. and Newcrest Resources Inc.
(―Newcrest‖). St. Vincent is the owner of 100% interest in the property pursuant to a purchase
and sale agreement with Newcrest dated October 29, 2010. St. Vincent is required to pay an
annual Maintenance Fee of $140 per unpatented lode claim to Bureau of Land Management and
$10.50 per unpatented lode claim to the Nye County Recorder‘s Office. The aggregate annual fee
for the Gabbs Project is $53,428 due September 1st of each year for the subsequent assessment
year.
1.2 GEOLOGY & MINERALIZATION
The Gabbs Property is underlain by a stratigraphic sequence of intermediate volcanic rocks and
shallow marine sediments that are intruded by a large mafic to ultramafic igneous complex
comprised of dark green massive equigranular gabbro, melagabbro, pyroxenite, and peridotite.
Monzonite bodies intrude the Triassic units and gabbroic complex. These intrusive bodies are
extremely significant as they host porphyry style Au-Cu mineralization found at the Sullivan,
Lucky Strike and Gold Ledge areas. The Car Body prospect by comparison is classified as an
epithermal gold system.
P&E Mining Consultants Inc. ii
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
Overlying the pre-Tertiary rocks are thick sequences of Tertiary intermediate and felsic volcanic
rocks. (Most often these contacts are unconformable.)
1.3 EXPLORATION STATUS
St. Vincent completed a 2,400 metre (7,875 feet) drilling program consisting of 10 reverse
circulation (RC) holes in March-April of 2011. The goal of this drilling was to expand the area of
known mineralization at the Lucky Strike area (6 holes) and test IP anomalies (4 holes) identified
by previous owner, Newcrest. Gold mineralization was encountered in 7 of 10 holes. Highlights
of the three most interesting holes (SVM-4, SVM-5 and SVM-6) are as follows: SVM-4 and
SVM-5 extended the mineralization 2,000 feet (610 metres) at Lucky Strike and SVM-6
encountered mineralization in at new area identified by an IP anomaly south of the Sullivan
mineralized zone.
1.4 MINERAL RESOURCES
P&E prepared an Inferred Mineral Resource estimate based on 494 drillhole records, consisting
of 397 ―historical‖ drillholes, 87 drillholes completed by Newcrest and ten RC drillholes recently
completed by St. Vincent. The ―historical drillholes‖ do not meet NI 43-101 and CIM guidelines
for the public reporting of a mineral resource. Historical drillholes were therefore used only to
define the extent of the mineralized deposits, and historical assay grades were not incorporated
into the mineral resource estimate. The P&E Mineral Resource estimate for the Gabbs Property
is reported at a cut-off grade of 0.40 g/t Au for the oxide deposits and 0.30 g/t Au for the non-
oxide deposits (Table 1.1). A summary of the mineral resource sensitivity is presented in Table
1.2.

(1) Mineral Resources which are not mineral reserves do not have demonstrated economic viability. The
estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title,
taxation, socio-political, marketing, or other relevant issues.
(2) The quantity and grade of reported Inferred Mineral Resources are uncertain in nature and there has been
insufficient exploration to define these Inferred Mineral Resources as an Indicated or Measured Mineral
P&E Mining Consultants Inc. iii

Resource, and it is uncertain if further exploration will result in upgrading them to an Indicated or
Measured Mineral Resource category.
(3) Mineral Resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum
(“CIM”), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the
CIM Standing Committee on Reserve Definitions and adopted by CIM Council
(4) Mineral Resources are reported within a conceptual pit shell.
(5) Inverse distance weighting of capped composite grades within grade envelopes was used for estimation.
(6) Composite grade capping of 5.00 g/t Au and 9000 ppm Cu was implemented prior to estimation.
(7) A bulk density of 2.70 t/m3 was used for tonnage calculations.
(8) A two year, November 30, 2011 trailing average copper price of US$3.70/lb and a gold price of
$1,350.00/oz were used along with an oxide process cost of $6.50/tonne, a sulphide process cost of
$9.50/tonne and G&A costs of $2.25/tonne.
(9) An oxide Au recover of 50% and a sulphide Au recovery of 90% were used
(10) Resources were estimated within an optimized pit shell utilizing pit slopes of 45 degrees and mining costs of
$1.50/tonne of rock.
(11) The conversion factor for AuEq is: AuEq=Au+Cu*1.67/10,000.

1.5 CONCLUSIONS & RECOMMENDATIONS
The Gabbs Project contains at least three separate Au-Cu porphyry prospects (Sullivan, Lucky
Strike and Gold Ledge) and one epithermal gold prospect (Car Body). Their close proximity to
each other suggests that they either share a common source which has possibly been structurally
dismembered from a once continuous system, or that multiple intrusive centers exist.
P&E recommends a two phase, results driven exploration program. Phase I of the exploration
program comprises a metallogenic study, structural analysis and drilling. Phase I has a proposed
budget of $3,621,480 and is expected to be completed between 2012 and 2013 (Table 1.3).

4.3 PERMITS
The United States Bureau of Land Management accepted St. Vincent‘s Surface Management
Notice on February 28, 2011 and the subsequent amendment submitted on March 31, 2011. This
accepted notice allowed St. Vincent to conduct its preliminary 2011 Drilling Program on the
Gabbs claims. St. Vincent posted reclamation bonds in the amount of US$15,000. Approval from
the Bureau of Land Management is required before additional exploration work is conducted. It
oversees and approves how much of the surface can be disturbed for exploration purposes (i.e. –
for drill pads or access roads). St. Vincent will be required to amend this notice in the future
before the Phase I and Phase II (2011-2012) Drilling Program begins and may be required to post
additional reclamation bonds.
No further permits are required at this stage of the Property‘s development. As long as the
Company pays the yearly claim fees, there is no work commitment required. The current
approved Notice of Intent is valid until March 31, 2013 unless the Company seeks a future
amendment for Phase I and Phase II drilling.
4.4 ROYALTIES/ENCUMBRANCES
Other than to secure the Company‘s performance under the promissory note described above,
there are no royalties or other encumbrances attached to the Gabbs claims.

PHYSIOGRAPHY
5.1 ACCESSIBILITY
The Gabbs Property is accessible from Reno by driving 56 km (34.8 mi) east on Interstate 80 to
Fernley (Exit 48), and 118 km (73.3 mi) east on US Highway 50 to Middlegate, then 50 km
(31 mi) south on Nevada State Highway 361 to Gabbs. From Gabbs, continue driving 7 km
(4.3 mi) southwest on Highway 361 to Pole Line Rd, then 3.5 km (2.2 mi) south to the center of
the Property (See Figure 4.1).
5.2 CLIMATE
The climate is typical for the arid high Great Basin Desert, with temperatures ranging from a
July average daily high of 95°F (33°C), with an average daily low of 56oF (13
oC) and a January
daily high at 45oF (7
oC) with an average daily low of 20°F (-7
oC). The extreme temperatures
reported for the Gabbs Property are 107oF (42
oC) and -37
oF (-27
oC). Annual precipitation is
5.84 in. (14.8 cm); although May is typically the wettest month, precipitation can occur
throughout the year.
The Gabbs Property is suited for exploration and mining for most of the year although temporary
weather delays can occur during the winter months of January through March.
5.3 LOCAL RESOURCES & INFRASTRUCTURE
A well maintained gravel road bisects the Property and a major power transmission line crosses
the project west of the Sullivan mine area. Very limited logistics can be found in the town of
Gabbs, though most service and supplies can be acquired in the town of Fallon, NV (pop. 8,525),
which is 120 km (75 mi) northwest of the site or the town of Hawthorne which is 90 km (55 mi)
west-southwest of the site.
Experienced mining personnel are available from the local communities of Gabbs, Hawthorne
and Fallon.
There is no water source on the property at present but there is sufficient groundwater that could
be accessed upon approval of a water drilling application.
St. Vincent has the legal right, including surface rights, to conduct exploration on its unpatented
claims and the right to operate a mine upon the completion of the permitting application with the
Bureau of Land Management and State of Nevada.
5.4 PHYSIOGRAPHY
The Property is situated in an area of dry rolling hills cut by shallow, dry drainages and is
bounded on the west by the Gabbs Valley, and on the east by the northeast trending Paradise
Range. The surface elevations for the project area range from 1,395 metres amsl (4,578 feet) on
the northwest corner of the claim block to 1,770 metres amsl (5,800 feet) on the southeast edge
of the Property (Figure 5.1).

6.0 HISTORY
6.1 REGIONAL EXPLORATION
Regionally the Gabbs Property is situated within the north-western end of the Fairplay Mining
District, an area that has been extensively and intensively explored by several companies and
individuals since the late 1800‘s (Wood, 2003; Fierst 2009).
Economic potential in the area was dominated by the Paradise Peak high sulphidation epithermal
gold-silver-mercury and discovered in 1983 and active until 1993 with a total production of
1.46 million ounces gold, 38.9 million ounces silver and 457 metric tonnes of mercury
(Sillitoe and Lorson, 1994; Plate 1). The Paradise Peak mine is adjacent to the south Property
boundary.
6.2 HISTORICAL EXPLORATION OF THE GABBS PROPERTY
The Gabbs Property, which has been intermittently explored by various operators since the
1970s, has over 500 holes drilled on the Property, half of these at the Sullivan porphyry gold-
copper prospect. A brief summary of the exploration history of the Gabbs Property is given in
Table 6.1.

1995 Arimetco
Arimetco acquired the Property in 1995 and drilled 4 core
holes at Sullivan and produced a Pre-Feasibility Study and
Plan of Operations with expectations to mine the Sullivan
resource (Arimetco International 1995 & 1996).
Arimetco stated that the Sullivan ore body consists of
―copper/gold ore containing approximately 17,162,000 tons of
oxidized ore grading 0.34% copper and 0.0255 ounces gold
per ton. It also hosts an additional 8,549,000 tons of copper
ore grading 0.31% copper‖ (Arimetco, 1995).*
Arimetco filed for bankruptcy on the property due to lack of
funding and low metal prices.
1996-2001 N/A Exploration activities on property ceased until 2002, when
Newcrest staked the property.
2002-2008 Newcrest
Resources
Newcrest staked the property in 2002 (excluding the Sullivan
area), and subsequently bought the Sullivan area in 2005 from
Arimetco in bankruptcy court. They drilled 24,765 metres
(81,250 feet) of reverse-circulation and core in 87 holes
through 2008. Newcrest performed petrographic studies
(Mason, 2008 and Thompson, 2006), extensive rock and soil
geochemical sampling, mapping (Candee, 2004; Chamberlain,
2008; Snyder, 2008) ground magnetics (Magee, 2007 and
Mackey, 2008), and induced polarization (Carlson, 2008)

Newcrest also produced a resource estimate for the Sullivan
that took in consideration of historic and current Newcrest
drilling (Maxlow, 2009). The Newcrest resource estimated is
given at 33,102,000 tonnes of ore grading 0.55g/t gold and
0.25% copper at a 0.3 g/t cut-off*. ―This represents a resource
of 585,000 ounces of gold and 82,755 tonnes of copper‖
(Maxlow, 2009)
2009-2010 Newcrest/St.
Vincent
Newcrest decided in 2009 to divest of all remaining properties
in the U.S. St. Vincent acquired the property in October, 2010.
*It should be noted that the resource estimates summarized above in Table 6.1 are historical in
nature and as such are based on prior data and reports prepared by previous operators. St.
Vincent is not treating the historic resource estimates as current. The work necessary to verify
the classification of the Mineral Resource estimates has not been completed and the resource
estimates therefore, cannot be treated as NI 43-101 defined resources verified by a Qualified
Person. The historical estimates should not be relied upon and there can be no assurance that
any of the resources, in whole or in part, will ever become economically viable.
6.3 PREVIOUS EXPLORATION
The most recent generation of exploration conducted on the Gabbs Property was that carried out
by Newcrest, during the period 2002 to 2008. The following is a brief summary of the
geochemical and geophysical surveying performed on behalf of Newcrest.
6.4 NEWCREST RESOURCES INC., GEOCHEMICAL EXPLORATION
Between 2002 and 2008 Newcrest collected about 900 surface rock chip samples from the Gabbs
Property. Sampling was concentrated around zones of known mineralization and, unsurprisingly,
anomalous to potentially economic gold and, to a lesser extent, copper values are concentrated in
these zones (Figure 6.1 and Figure 6.2). Sampling outside the mineralized zones mostly returned
low values and no prospect scale geochemical zoning is apparent. A soil survey was undertaken
on the Gabbs claim block in March and April of 2008. A total of 1,383 soil samples were
collected at 50 metres spacing along lines 200 metres apart. Following an orientation survey of
30 samples that were analyzed for a suite of 30 elements, it was determined that the remainder of
the survey could be done for gold and copper only since no anomalous pathfinder elements
appeared to correlate with gold and copper mineralization. (Fierst, 2008; Figure 6.3 and Figure
6.4). Anomalous copper and, to a lesser extent, gold values are concentrated around the Sullivan,
Gold Ledge and Lucky Strike porphyry gold-copper zones. Samples taken outside these
mineralized zones mostly returned low values and no prospect scale geochemical zoning is
apparent. The Car Body zone was not covered by the soil survey.

6.5 NEWCREST RESOURCES INC. GEOPHYSICAL EXPLORATION
Combined magnetic and induced polarization and resistivity (IP) geophysics can be effective in
identifying and characterising porphyry gold-copper deposits. These deposits commonly have a
gold-copper mineralized, potassic altered, magnetite-rich core centred on a porphyry stock and
characterised by a magnetic high anomaly. This is often surrounded by an annular zone of barren
or weakly gold-copper mineralized, pyrite-rich, phyllic alteration characterised by magnetic
low/conductivity high anomalies.
Ground magnetic surveying was undertaken at the Gabbs Project in 2007 and induced
polarization and resistivity (IP) surveying done in 2008. The geophysical surveys identified
anomalous areas, but no clear bulls-eye anomalies typical of large mineralized porphyries were
P&E Mining Consultants Inc. Page 19 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
detected. The data was recently reviewed by a consulting geophysicist, reprocessed and approved
for interpretation, (Ellis, 2011). A deep source for the mineralized quartz monzonite porphyries
is postulated to exist west of the Sullivan deposit and east of Lucky Strike and Gold Ledge
prospect (Fierst, 2009, Ellis, 2011). This may be indicated by the existence of a broad
chargeability anomaly on the 450 metre depth slice (Figure 6.5).
A broad east-west magnetic low anomaly between Lucky Strike and Gold Ledge separates
individual magnetic highs (Figure 6.6) the latter thought to reflect Jurassic gabbro/pyroxenite
and to some extent Triassic meta-andesite (basement). The magnetic lows may indicate a thrust
fault that controlled intrusion or tectonic emplacement of non-magnetic quartz monzonite
(Ellis, 2011). Alternatively, the magnetic lows may identify magnetite destructive alteration in
basement rocks. Support for the latter interpretation is the east-west elongate magnetic low that
corresponds with the pyrite-mineralized, phyllic-altered, Tertiary volcanics at Car Body
(Ellis, 2011). Two major north-northwest-striking lineaments flank the Gold Ledge zone in the
magnetic image (Figure 6.6) and have been interpreted as the margins of a ―volcanic‖ rift (Fierst,
2009) perhaps related to ―basin and range‖ tectonics.

St Vincent Minerals is considering conducting IP survey lines between the Sullivan and Gold
Ledge mineralized zones, over the Car Body epithermal prospect and the South Sullivan area
(south of drill holes SVM-6, SRD-14 and SD-21). Any IP survey is expected to be augmented
with gravity survey data.
6.6 PREVIOUS DRILLING
6.6.1 Newcrest Diamond Drilling 2004-2009
The most recent drilling prior to St. Vincent Minerals US Inc. acquiring the Property was
completed by Newcrest. The drilling was completed between 2004 and 2008 comprising 87 RC
and core holes (24,765 metres- 81,250 feet).
P&E Mining Consultants Inc. Page 21 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
The initial target on the Property was at the Car Body prospect, based on previous drilling by
Placer U.S. Inc. and reconnaissance mapping and sampling by Newcrest. Car Body is a very
nuggety epithermal gold vein target hosted in a variety of Tertiary volcanic rocks. The Car Body
prospect was drill-tested in May of 2004, and again in early 2006 with two rounds of drilling in
31 RC holes (5,694 metres). Although many holes encountered gold mineralization, it was
difficult to locate continuous mineralization and emphasis was shifted from the Car Body area to
Sullivan. During the second round of Car Body drilling in 2006, eight RC holes (1,472 metres)
were drilled in the Gold Ledge area. Low-level gold and copper were encountered in 7 of the 8
holes, and warranted future drilling.
In mid-2006, data from the previous drilling at Sullivan were compiled. It became apparent that a
porphyry gold-copper target was present and that potential existed both at depth and laterally to
expand the existing oxide resource. Diamond drilling commenced in September of 2006, and
continued until September of 2007 for a total of 4,842 metres in 13 core holes. The first two core
holes were drilled in the oxide resource area to determine if the previous grades were reasonable.
A brief description of the various drilling phases is given below. A list of some of the significant
core intercepts is given in Table 6.2. A drill hole location plan map is given in Figure 6.7.

St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
6.6.2 2004 Drill Program
―Initial drill testing of the Car Body prospect in May 2004 consisted of 10 RC drill holes (G-1 to
G-10; Figure 6.7). Average depth was 183 metres, and none of the holes were surveyed down-
hole. Among the mineralized intercepts was a 3.05 metre intercept in hole G-2 averaging
22.6 grams/ton. Re-assays of several mineralized intercepts yielded poor reproducibility of gold
assays with widely varying gold values. Drilling was done with a center-return hammer drill,
collecting 100% of the sample‖ (Fierst, 2009, p. 34).
6.6.3 2006 Drill Program
From December 2005 to June 2006, 29 RC holes (G-11 to G-39). were completed in the Car
Body (21 holes) and Gold Ledge areas (8 holes) None of the holes in this program were surveyed
down-hole. The Car Body holes confirmed the existence of coarse ―nuggety‖ gold (Thompson,
2006). Drilling in the Gold Ledge area encountered copper-gold mineralization associated with
felsic intrusive rocks. Drilling was done with a center-return hammer, collecting 100% of the
sample‖ (Fierst, 2009, p. 34-36).
6.6.4 2006-2007 Drill Program
―From September 2006 to September 2007, 13 diamond holes were completed at the Sullivan
prospect (SD-1 to SD-13), and 2 diamond ―twins‖ of RC holes were drilled at the Car Body
prospect. All drill holes in this program were surveyed by downhole gyroscope. The first
2 Sullivan holes were confirmatory holes for previously outlined oxide mineralization in the
Sullivan ―sill.‖ SD-3 discovered sulphide mineralization offset from the oxide mineralization to
the southeast across an inferred fault. The remaining drill holes of the program sought to extend
mineralization away from the oxide resource. Although the 2 diamond ―twins‖ in the Car Body
area encountered mineralization in many of the same zones which the initial RC holes
intercepted mineralization, they failed to accurately reproduce the grades encountered in RC
drilling‖ (Fierst, 2009, p. 36).
6.6.5 2008 Drill Program
―From April to August 2008, 7 RC holes, including 1 RC pre-collar (SR-1 to SR-5 and SRD-14
to SRD-15) and 7 diamond holes SD-16 to SD-21 and SRD-15) were drilled at the Sullivan
prospect, and 16 RC holes (G-40 to G-55) and 4 diamond holes (GD-3 to GD-6) were drilled at
the Lucky Strike-Gold Ledge area. All drill holes in this program were surveyed by downhole
gyroscope. At Gold Ledge, a mineralized monzonite ―sill‖ similar to the one at Sullivan, was
encountered in and delineated by RC drilling (G-40 to G-48). Efforts to significantly increase
mineralization at Sullivan were unsuccessful; however, unexpected shallow mineralization
(beginning at 21 m) in monzonite was discovered to the southwest of Sullivan in RC hole SRD-
14, later drilled with core by hole SD-21‖ (Fierst, 2009, p. 36).

6.7 HISTORIC RESOURCE ESTIMATES
The resource estimates summarized below and in Table 6.4 below are historical in nature and as
such are based on prior data and reports prepared by previous operators and are not in
compliance with NI 43-101. A Qualified Person has not done the work necessary to verify the
historical estimates as current estimates under NI 43-101 and the estimates should not be relied
upon. There can be no assurance that any of the resources, in whole or in part, will ever become
economically viable. The Company is not treating the historical estimates as current Mineral
Resources or Mineral Reserves. The Company has completed the necessary work to establish a
current Mineral Resource on the Gabbs Property as set out in section 15 of this Report.

In 1990, Gwalia produced a pre-feasibility study based on 14 holes drilled that stated that the ore
body at Sullivan contained 12,680,000 tonnes at 0.0267 opt (0.834 g/t) gold and 0.34% copper
(Fierst, 2009)
In 1995 Arimetco acquired the property and produced a Pre-Feasibility Study and Plan of
Operations with expectations to mine the Sullivan resource. Arimetco stated that the Sullivan ore
body is a ―copper/gold ore containing approximately 17,162,000 tons of oxidized ore grading
0.34% copper and 0.0255 ounces gold per ton. It also hosts an additional 8,549,000 tons of
copper ore grading 0.31% copper‖ (Arimetco, 1995).
Newcrest began work on the property in 2002 and after extensive drilling through
2008 estimated the resource at Sullivan as 33,102,000 tonnes of ore grading 0.55g/t gold and
0.25% copper at a 0.3 g/t cut-off. ―This represents a resource of 585,000 ounces of gold and
82,755 tonnes of copper‖ (Maxlow, 2009). An oxide resource of 12.7 million tonnes of 0.91 g/t
gold and 0.34% copper was previously estimated (Job and Singh, 2010).

6.8 HISTORIC METALLURGY
Prior to 2000 numerous metallurgical tests (indicated in the table below) were carried on
primarily oxide and transition mineralization at the Gabbs Gold-Copper Property. Studies
investigating heap leaching, whole ore cyanidation, gravity separation and a dual process of
selective floatation or acid leaching followed by a cyanide leach of the residue for gold were
undertaken with unsatisfactory results given the much lower Au and Cu metal prices that
prevailed during those times. Table 6.5 below shows the past metallurgical studies conducted on
the Gabbs Project by various companies. All of the entries in the table are stored at the SVM
Fallon office/core shed.

Metallurgy
Given the discovery of the much larger amounts of sulphide mineralization (forming the bulk of
this resource estimate) during the last decade the pre-2000 metallurgical studies are of only very
limited applicability. It seems probable that a more conventional approach may be appropriate –
flotation of a copper concentrate (which must be saleable grade) possibly followed by
cyanidation of a cleaner tail (for example) for gold. Metallurgical test work by the GUSA lab
(Gwalia-Sullivan Pre-feasibility Study 1990) with a two stage leach (acid & cyanide) indicated
recoveries of 88% to 90% for Au and 76% to 78% Cu. It has also been suggested that the
cyanidation of a Cu rougher concentrate for Au recovery may also be a potentially viable process
option. A testwork program to pursue these recovery methods would be warranted.

7.0 GEOLOGICAL SETTING & MINERALIZATION
7.1 GEOLOGICAL SETTING
The following geological description of the Gabbs Property draws heavily from material
summarized by Clark (2010) as originally contained in Newcrest reports by Candee, 2004,
Wood, 2005 Maxlow, 2009, and Fierst, 2009.
7.1.1 Regional and Local Geology
The oldest rocks exposed in the district are meta-sedimentary rocks of the Excelsior Formation.
These rocks range in age from Triassic to late Jurassic and consist of sedimentary and volcanic
rocks deposited along an island arc. The island arc formed within the center of an ortho-
geosyncline that developed along the continental margin and traversed central Nevada separating
deep marine rocks to the west from shallow shelf carbonates to the east (Wood, 2005). Local
Triassic and Jurassic rocks consist of subaqueous andesite flows, tuffaceous rocks and associated
andesite and gabbro intrusions, locally interbedded with conglomerate and deltaic deposits of
pelitic and clastic rocks with minor limestone. In the Jurassic the first large intrusions were
emplaced as the ancestral Sierra-Nevada batholith and Walker Lane structural zone formed.
During this time smaller plutons were emplaced throughout central Nevada. Several large
Jurassic thrust faults developed, placing terrestrial rocks of the volcanic highland over the
carbonate shelf rocks to the east. During the Cretaceous much of Nevada was below a shallow
sea and only a few scattered remnants of volcanic and sedimentary rocks are preserved due to
uplift and erosion. Intrusive activity reached its peak during the Nevadan orogeny (90 to 60 Ma)
with the formation of the Sierra-Nevada batholith and numerous smaller equigranular to
porphyritic plutons.
The oldest rocks exposed in the project area are intermediate volcanic and shallow marine
sedimentary rocks which comprise a sequence of dark greenish-grey to black finely porphyritic
andesite flows, and poorly sorted andesitic fragmentals intercalated with finer volcanic
sediments. This unit is thought to be correlative to the intermediate volcanic sequence unit
recognized by the United States Geological Survey (―USGS‖) as the Excelsior Formation, 5 km
southwest of the Gabbs Project. The Excelsior Formation is considered Triassic in age. Figure
7.1 is a geological map of the Gabbs Property while Figure 7.2 displays the local Stratigraphic
Column.
Interbedded calcareous siltstones, sandstones and conglomerate overlie the intermediate volcanic
sequence. These sediments are found throughout the project area, but are particularly abundant in
the Car Body area. Scattered outcrops of sediments also occur between Lucky Strike and Gold
Ledge (see Figure 7.1). USGS mapping suggests the sediments largely belong to the Luning
Formation, and the Gabbs and Sunrise Formations undivided. The sediments are believed to have
been deposited in an off-shore marine subtidal environment as part of an early Mesozoic
volcanic arc terrain development (Kleinhampl & Ziony, 1984).
7.1.2 Property Geology
The intermediate volcanic sequence and shallow marine sediments are intruded by a large mafic
to ultramafic igneous complex comprised of dark green massive equigranular gabbro,
melagabbro, pyroxenite, and peridotite. Gabbroic rock outcroppings are extensive in the Lucky
Strike and Sullivan areas. Elsewhere on the property the gabbroic rocks are covered by talus and
P&E Mining Consultants Inc. Page 28 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
colluvium, which obscures contacts and structural relations. Historic drilling indicates that the
gabbroic complex continues under cover and coincides with large magnetic highs in both the
Sullivan and Lucky Strike areas. The gabbroic complex is interpreted as being a differentiated
mafic to ultramafic intrusion, where the earlier formed liquidus minerals of pyroxene, olivine
and magnetite gravity accumulated and produced ultramafic rocks in the lower part of the
intrusion, and melagabbro and gabbro in the middle to upper parts (Mason, 2008). The contact
between upper mafic and lower ultramafic rocks has not been observed in outcrop. The gabbroic
rocks at the Property have not been dated, but stratigraphic relationships with older and younger
units imply they were emplaced during the Jurassic and Cretaceous (see Figure 7.2).
Many monzonite bodies intrude the Triassic units and gabbroic complex. These intrusive bodies
are extremely significant as they host porphyry style Au-Cu mineralization found at the Sullivan,
Lucky Strike and Gold Ledge areas. The monzonites are variable in composition and texture and
range from fine-grained feldspar monzonite porphyry to fine-medium grained equigranular
quartz monzonite to medium-grained equigranular monzodiorite (Mason, 2008).

Figure 7.2 Gabbs Project Stratigraphic Column
(Source: Fierst, 2009)
The monzonite bodies have extensive sill-like geometry, variable thickness (~1 m to <100 m)
and diverse orientations. Based on calculations of drilling intercepts, the monzonite sill in the
Lucky Strike area has an average orientation of N46°E/25°SE with distinct and sharp contacts
with adjacent rocks. In the Sullivan area, orientations of the monzonite sill calculated from
P&E Mining Consultants Inc. Page 31 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
drilling show differing orientations for the upper and lower contacts. The upper contact has an
average orientation of S40°E/31°SW, while the lower contact has an average orientation of
S86°E/24°SW (Fierst, 2009). It is yet to be determined if the bodies are sills, rotated dikes or
structurally transported slices. Recent work (Pratt & Ponce, 2011) suggests that the mineralized
bodies are unlikely to be fragments or slices of a dismembered porphyry system stock, but
instead are comprised of a series of widely distributed sills, dikes or plugs. Pratt & Ponce also
indicate ―that there is a strong possibility that Sullivan sill links directly beneath the volcanic
cover with Gold Ledge and from there onto the Kona prospect in the west.‖ Petrographic
descriptions from drill core at Sullivan suggest the different monzonite bodies are genetically
related (Mason, 2008). The monzonite intrusives are considered to be Jurassic-Cretaceous in age
and currently, in some rare occurrences, appear to intrude the overlying Tertiary volcanic rocks,
which may suggest multiple intrusive events continuing into the Tertiary.
Overlying the pre-Tertiary rocks are thick sequences of Tertiary intermediate and felsic volcanic
rocks.
In some areas, a coarse epiclastic or conglomerate unit lies at the base of the Tertiary section.
The Tertiary volcanic rocks comprise an older sequence of dark-brown to grey porphyritic
andesite lavas and tuffs overlain by rhyolite ash flow tuffs and intrusives. The youngest rocks
found on the property are east-west trending rhyolite dikes that cut all pre-Tertiary and Tertiary
rocks. They vary from rhyolite to latite in composition and are generally greater than 20 m wide
with sharp contacts. The dikes share a similar orientation to a large EW trending linear feature
observed in the magnetics (Fierst, 2009). Tertiary volcanic and volcaniclastic rocks host the
epithermal gold mineralization in the Car Body area as well as at the adjacent, Paradise Peak
deposit which abuts the Gabbs claim block to the south. The Paradise Peak Mine hosts a high
sulphidation epithermal system from which FMC produced 1.46 M oz Au, 38.9 M oz Ag, and
457 tonnes Hg in an open pit/heap leach operation from 1985-1993.
7.2 STRUCTURE
A number of interpreted folds exists within the Triassic sequence, particularly at the Car Body,
Gold Ledge, and Lucky Strike mineralized areas (Figure 7.3). These folds are possibly related to
emplacement of the Mesozoic-aged Luning-Fencemaker allochthon. Some folding also appears
to be accompanied by the intrusion of igneous rocks as evidenced by Triassic sediments at Car
Body forming a southeast facing synclinal fold feature that wraps itself around a large
monzodiorite and quartz monzonite body (Fierst, 2009).
Low-angle faults, including thrust faults in the project area, are likely associated with the
Luning-Fencemaker event, as well as possible later events. Low-angle detachment faulting has
been implied at the Paradise Peak Mine and areas to the south of the Gabbs Property (Fierst,
2009). High-angle faulting occurs primarily in two orientations: north-northeast and west-
northwest. Northeast trending faults are assumed to be associated with Basin and Range
extension. Northwest trending faulting is sub-parallel to Walker Lake structures. Many of the
northwest structures appear to be attendant with mineralized quartz veins. Many of the northwest
structures are accompanied with mineralized quartz +/- carbonate veins (Fierst, 2009). A recently
completed detailed study of the structural setting of the mineralization at the Property (Pratt &
Ponce, 2011) indicates that ―the Triassic basement complete with the Cretaceous porphyries was
faulted prior and during the deposition of the Tertiary volcanic rocks. The report goes on to
suggest that the Tertiary volcanics diplay contemporaneous fault control, lateral facies changes
P&E Mining Consultants Inc. Page 32 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
and draping over strong fault-controlled (listric and half-graben) topography‖ (Pratt & Ponce,
2011).

(Source: Fierst, 2009)
7.3 ALTERATION
The Triassic rocks have been described as pervasively metamorphosed to the lower greenschist
facies. The metamorphism and alteration in the project area is mostly localized and largely found
to be contact-related near mafic intrusions. Seritization and local silicification are the alteration
type most commonly found in the local Triassic sequence. The Triassic volcanic sequence also
shows evidence of metasomatism and minor calc-silicate alteration (skarn). This is very apparent
in the Lucky Strike area where a large gabbroic complex is exposed. Calc-silicate alteration in
this area is characterised by massive epidote, magnetite and minor actinolite localized around
intrusive contacts (Fierst, 2008). Elsewhere, the intermediate volcanic sequence is weakly to
moderately recrystallized.
Like the volcanic sequence, metasomatism has also affected the sediments, from simple
recrystallization to several metres of marblization along the intrusive contacts. The sediments
appear to lack sufficient calcium carbonate to form true skarn (Fierst, 2008).
Alteration associated with porphyry-style mineralization includes potassic, phyllic and possibly
sodic-calcic. Mafic-ultramafic intrusive rocks are interpreted to be either sodic-calcic or potassic
alteration (Fierst, 2009). Alteration zonation associated with porphyry mineralization is weakly
defined in the Lucky Strike area (Figure 7.4), and largely absent at Sullivan.
P&E Mining Consultants Inc. Page 33 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
The Tertiary volcanic rocks are sericitized, propylitically, and argillically altered, with lesser
silicification. Intermediate Tertiary volcanic units contain minor primary magnetite (responsible
for a stippled pattern in magnetic images), and commonly have mafic crystals altered to chlorite
(Fierst, 2008).

(Source: Fierst, 2009)
7.4 MINERALIZATION
Mineralization and hydrothermal alteration at the Gabbs Project occurs in two principal styles:
Porphyry gold-copper-molybdenum with associated potassic, phyllic and
propylitic alteration, and;
Volcanic-hosted gold-mineralized hydrothermal breccias with associated phyllic
and argillic alteration.
There are four separate prospects three of which (Gold Ledge, Lucky Strike and Sullivan) are
classed as a porphyry gold-copper deposits with the remaining Car Body prospect being a
nuggety epithermal gold deposit.
P&E Mining Consultants Inc. Page 34 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
7.4.1 Porphyry Gold-Copper Mineralization
Porphyry copper deposits are among the largest and most valuable mineral-deposit types on earth
and are the most important source of global copper supply. The deposits typically contain
hundreds of millions of tons of mineralized rock and millions of tons of copper, with lesser
amounts of molybdenum, gold, and/or silver (Ludington et al., 2009).
Porphyry copper deposits form in subduction-related magmatic arcs, and northern Nye County
contains parts of at least three such arcs, one of Late Triassic to Jurassic age, one of Cretaceous
to Palaeocene age, and one of Oligocene and Miocene age. Although no large porphyry copper
deposits are known in the northern Nye County region, at least two sites provide specific
analogues to deposits that may exist. Royston is about 40 km northwest of Tonopah, on the Nye-
Esmeralda County line while the Sullivan Prospect occurs on the Gabbs Property. The Lucky
Strike and Gold Ledge prospects on the Gabbs Property are also considered to host porphyry
style mineralization.
7.4.2 Sullivan, Lucky Strike and Gold Ledge Prospects
The Sullivan deposit, also known as Cuervo, is about 4 km northeast of the Paradise Peak
epithermal gold deposit (Ludington et al., 2009) and is exposed beneath at the surface where the
monzonite ―sill‖ daylights. The deposit is a vein stockwork hosted in Late Cretaceous monzonite
porphyry. The veins contain copper and gold. Glamis Gold Ltd. excavated 30k tonnes from a
surface pit for test leaching in the late 1980s (Ludington et al, 2009).
Porphyry gold-copper-molybdenum mineralization occurs in two shallow dipping sill-like
monzonite porphyry bodies at the Sullivan and Lucky Strike zones and a vertically continuous
body, possibly a plug, at Gold Ledge. The ―sills‖ range from 1 m to greater than 100 m thick and
are laterally extensive (Fierst, 2009). Average orientation at Lucky Strike is N46oE dip 25
oSE
and Sullivan varies from N140oE dip 31
oSW (upper contact) to N94
oE dip 24
oSW (lower
contact). The ―sills‖ may be rotated dikes or tectonically emplaced slabs of a porphyry stock. A
longitudinal section through the Sullivan prospect is shown in Figure 7.5 while Figure 7.6
depicts a representative cross section.
Porphyry style mineralization at Gabbs is characterised by stockworks, grain boundary filling
and disseminations of early sulphide +/- biotite veinlets. These are mostly cut by quartz-
chalcopyrite ―A‖ veins and less common ―B‖ veins accompanied by potassic alteration (biotite
and K feldspar). Quartz-sericite-pyrite (phyllic) alteration is common and usually accompanied
by, sometimes thick, quartz-pyrite-chalcopyrite-molybdenite ―D‖ veins. Thick, massive to
coarsely crystalline, sometimes ribbon-textured, pinching and swelling, mesothermal quartz-
chalcopyrite-chalcocite ―D‖ veins occur in monzonite porphyries and in surrounding Triassic
meta-volcanic and sedimentary country rocks. Visible gold was noted in one such vein. Late
veins of pink manganoan calcite cut mineralized monzonite porphyry in places and selenite (after
anhydrite) was noted at Lucky Strike (Jemielita, Richard 2011).
The textures, mineralogies and compositions of the various monzonite porphyry, gabbro and
associated ultramafic lithologies and hydrothermal alteration facies at the Gabbs Property have
been confirmed by thin section petrography (Mason, 2008). Selected diamond drill core
intersections in porphyry gold-copper zones at Gabbs are summarised below:

depth; copper is from 0.1 to 1.4% to 84 metres (276 feet) depth. Mineralization only occurs in
monzonite (Jemielita, 2009).
7.4.6 Epithermal Gold-Silver Mineralization
Epithermal gold-silver deposits are important sources of gold and silver worldwide (Simmons
and others, 2005). They form at less than 1.5 km depth and less than 300°C in mainly subaerial
hydrothermal systems (Henley and Ellis, 1983; Hedenquist and Lowenstern, 1994). These
hydrothermal systems developed in association with calc-alkaline, alkaline, and less frequently,
tholeiitic magmatism, most commonly in volcanic arcs at convergent plate margins, but also in
intra-arc, back-arc, and post-collisional rift settings. In addition, some non-magmatically heated
epithermal deposits that formed by deep circulation of meteoric water along steep extensional
faults are present in northern Nevada. Epithermal gold-silver deposits have highly variable
characteristics, including ore and alteration mineralogy and gold, silver, and base metal (Cu, Pb,
Zn) contents, and formed in diverse geologic environments (Hedenquist and others, 2000;
P&E Mining Consultants Inc. Page 38 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
Sillitoe and Hedenquist, 2003; Simmons et. al., 2005). Two principal types of deposits are low-
sulphidation (also called quartz-adularia or adularia-sericite) and high-sulphidation (also called
quartz-alunite or acid-sulphate).
Epithermal gold-silver deposits have been the largest producing deposits in northern Nye County
since discovery of silver-rich veins in the Tonopah district in 1900. Round Mountain has the
largest total production and is the largest current producer in the region. It has produced more
than 373,000 kg of gold and 311,000 kg of silver since 1907; 14,800 kg of gold and 28,900 kg of
silver were produced in 2008.
In northern Nye County, isotopically dated epithermal gold-silver mineralizing systems range in
age from about 26 to 17 Ma. High-sulphidation deposits generally form in or near
eruptive/intrusive centers and have a larger magmatic component than low-sulphidation deposits.
Their formation is related to degassing of shallow, oxidized magma bodies and the circulation of
acidic hydrothermal fluids released from these magmas.
Paradise Peak, a zone adjacent to the Gabbs Property, is the only significant high-sulphidation
deposit in the Gabbs region but several other large deposits occur nearby in Esmeralda and
Mineral Counties.
Low-sulphidation deposits are common in the western half of northern Nye County and are
widespread throughout much of the northern Great Basin.
On the Gabbs Property the Car Body prospect is an epithermal gold deposit hosted in similar
Tertiary volcanic rocks to the Paradise Peak deposit. Whereas Paradise Peak was a high-
sulfidation epitermal gold deposit, Car Body is of the low-sulfidation type. The Gold Ledge area
also has potential to contain an epithermal gold deposit.
Selected diamond drill core intersections in the epithermal gold Car Body zone at Gabbs are
summarised below.
7.4.7 Car Body Zone
The Car Body zone at the Gabbs Project is characterised by intrusive, magmatic-hydrothermal
breccias best observed in drill core. The breccias are hosted by Miocene upper andesite-dacite
and middle rhyolite volcanic and intrusive lithologies best exposed in the adjacent Paradise Peak
mine (Sillitoe and Lorson, 1994). Breccia textures were recognised previously from petrography
on RC drill hole chips from the Car Body zone (Thompson, 2006). Coarse gold is reported from
RC drill chips from Car Body but gold values are very variable and difficult to reproduce
between RC and core indicating a strong gold ―nugget effect‖ (Fierst, 2009). Results from two
core holes are summarised below:
Hole GD-01; 0-244 metres (0-801 feet); Gold values are mostly at detection limit to weakly
anomalous (<10 ppb). From 37 to 94 metres (121 to 308 feet) gold values are moderately to
strongly anomalous (>10 ppb) up to a maximum 0.4 oz/t gold. The intersection dominated by
phyllic-altered andesite-rhyolite intrusive breccias.
Hole GD-02; Gold ranges up to 5.691 g/t. From 20 to 41 metres (65 to 135 feet) is 21 metres (70
feet) of 0.02 g/t gold including 4.2 metres (13.7 feet) of 0.05 oz/t gold. The intersection is
P&E Mining Consultants Inc. Page 39 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
dominated by quartz-sericite-pyrite- (phyllic-) altered, andesite-rhyolite intrusive breccias
(Jemielita, 2009).
7.4.8 Alteration Mineralogy
According to Fierst (2009) mineralization related alteration in Triassic basement lithologies is
mostly sericitic with local silicification with minor skarnoid (epidote, magnetite and minor
actinolite) and marble formation around gabbro intrusive contacts.
Monzonite porphyries are potassic, phyllic, and sodic-calcic altered. Mineral assemblages
comprise sericite-pyrite (+/- chlorite, tourmaline, calcite, albite, rutile), interpreted as phyllic
and/or sodic-calcic alteration, or albite-K-feldspar-biotite-sericite (+/- calcite, chlorite, epidote,
sphene, rutile), interpreted as potassic alteration. Primary ferromagnesian minerals in monzonites
have been largely replaced by biotite, chlorite and/or sericite. Plagioclase has been largely
altered to albite or sericite. Fine-grained felsic groundmass has been largely replaced by
potassium feldspar and/or sericite (Mason, 2008).
Mafic-ultramafic intrusive rocks are dominated by actinolite/tremolite-biotite-epidote-albite-
calcite-chlorite (+/- talc, serpentine, sphene) alteration interpreted as either sodic-calcic or
potassic alteration. Most pyroxene in the rock has been completely altered to actinolite or
tremolite (and locally biotite) and much of the plagioclase has been altered to albite and/or
epidote. Olivine in peridotite has been altered to serpentine and chlorite. In ultramafic rocks
which have undergone high strain, primary minerals have been entirely altered to talc-calcite-
biotite (Mason, 2008). Mafic intrusive rocks contain both primary and secondary magnetite. No
clear evidence for alteration overprinting has been found.
Mineralization at the project lacks clear zonation of alteration and/or geochemistry that might
vector towards a central source porphyry stock (Lowell and Guilbert, 1970). Apparent alteration
zonation at Lucky Strike is thought to be lithologically controlled (Fierst, 2009).

8.0 DEPOSIT TYPES
Metalliferous mineral deposits are an important part of the economy in Nevada. Many of these
deposits have a close spatial and temporal association with intrusive centers and several different
types of genetically related deposits can occur in clusters around these centers. Important
resources of Cu, Mo, W, Au, Ag, Pb and Zn may exist in deposits related to intrusive rocks, such
as porphyry deposits, skarn deposits, polymetallic vein and replacement deposits, distal
disseminated Ag-Au deposits, and some types of epithermal Au-Ag deposits.
There are currently four separate mineralized areas found on the Gabbs Project: The Sullivan,
Lucky Strike, and Gold Ledge are considered to be gold-copper porphyry deposits. The Car
Body is considered to be an epithermal gold deposit. Although it was thought that the Car Body
was similar in origin to the Paradise Peak property, which is adjacent to the Gabbs Property to
the south, the Paradise Peak is a high sulphidation epithermal deposit while Car Body is situated
in a low-sulphidation epithermal environment. Figure 8.1 shows a schematic diagram of a
porphyry system and associated mineralization types.
Figure 8.1 Model of Relationship of Low-Sulfidation and High-Sulfidation to Co-
Genetic Sub-volcanic Intrusions and Associated Porphyry-Style Ores
(Source: Saunders, J. and Hames, W., 2006)
8.1 GOLD-COPPER PORPHYRY DEPOSITS
Gold-copper porphyry deposits are emplaced in a variety of subduction-related settings and are
underlain by both oceanic and cratonic crust in either extensional or compressional tectonic
regimes. This style of deposit is associated with composite porphyry stocks of steep, cylindrical
form that commonly intrude coeval volcanic piles. Stocks and associated volcanic rocks range in
composition from low-potassium calc-alkalic through high-potassium calc-alkalic to potassic
alkali (Figure 8.2). Much of the copper and gold was introduced during potassium-silicate
alteration (+/- amphibole and other calcic minerals).
P&E Mining Consultants Inc. Page 41 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
Gold-copper porphyry deposits contain many of the geological features of regular copper
porphyry deposits with gold present in veinlet stockwork and as disseminations within or
immediately contiguous to porphyry stocks. These porphyry stocks are the centre of more
extensive hydrothermal systems and may sometimes host other types of gold deposits, such as
high- and low-sulphidation epithermal veins. The Gabbs Property features low-sulphidation
systems in the vicinity of the Sullivan, Lucky Strike, and Gold Ledge deposits. Paradise Peak, a
high sulphidation system, is located to the south of the Gabbs Property and Car Body is located
south of the other gold-copper porphyry systems on the Gabbs Property.

and Epithermal Cu-Au-Mo-Ag Mineralisation
(Source: Corbett, 2009)
8.2 LOW-SULFIDATION EPITHERMAL SYSTEMS
Low sulphidation epithermal Au-Ag deposits are distinguished from high sulphidation by the
sulphide mineralogy and their formation at a greater distance from causative magma bodies.
They are formed by geothermal fluids – reduced, diluted, with neutral pH‘s – mixed with ground
water. They originate in dilational, rift-style structural settings. The ore fluids in a low
sulphidation epithermal deposit also generally contain a smaller magmatic component. Pyrite,
sphalerite, galena, and chalcopyrite typically occur within quartz veins with local carbonate and
associated near neutral wall rock alteration (illite clays), deposited from dilute hydrothermal
fluids. Low sulphidation veins are typically well banded with each band representing a separate
episode of hydrothermal mineral deposition. There are three main types of rising hydrothermal
fluids (Figure 8.3) that contribute towards low sulphidation vein formation:
P&E Mining Consultants Inc. Page 42 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
Meteoric dominated water which commonly form shallow circulating cells and
deposit barren quartz, which has not come into contact with buried intrusion
sources for metals and so are commonly barren.
Magmatic-meteoric waters developed where meteoric waters migrate sufficiently
deep to come in contact with magmatic sources for metals and so contain low
grade mineralization within disseminated sulphides.
Magmatic dominant waters derived from intrusion sources for metals at depth.
These types of sulphide veins contain the highest precious metal values associated
with sulphides.
Figure 8.3 Model Accounting for Varying Hydrothermal Fluids Contributing to the
Development of Banded Low-Sulphidation Epithermal Au-Ag Veins
Containing Many Varied Vein Elements.
(Source: Corbett, 2009)
Quality low sulphidation epithermal Au-Ag mineralization is best developed in geological
settings where factors such as lithology, structure, and the mechanisms of Au deposition have a
great influence.
Lithological control occurs mainly as competent or brittle host rocks which develop through
going fractures as vein hosts. The permeability of the host rock is locally important. In
interlayered volcanic sequences epithermal veins may be confined to only the competent rocks
while the intervening less competent sequences host only fault structures.
P&E Mining Consultants Inc. Page 43 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
Structures act as fluid pathways and more dilational portions of the host structures may represent
sites of enhanced fluid flow and promote the development of ore shoots which host most
mineralization in many low sulphidation vein systems. Fault intersections host ore shoots at sites
of fluid mixing.
The various mechanisms of Au deposition can greatly affect the Au grade:
Cooling in the case of many coarse sulphides with low grade Au contents.
Rapid cooling promoted by quenched magmatic fluids producing fine sulphides or
by the mixing of ore fluids with deep circulating meteoric waters.
The mixing of oxygenated ground waters with ore fluids at elevated crustal
settings produces elevated Au grades producing hypogene haematite in the ore
assemblage.
The mixing of low pH waters, created by the condensation of H2S volatiles above
the water table, is responsible for the development of near surface acid sulphate
caps and provides the highest Au grades. This mechanism of Au deposition is
characterized by the presence of hypogene kaolin, including halloysite within the
ore assemblage.
Styles of low sulphidation Au are distinguished according to mineralogy and
relation to intrusion source rocks and influence precious metal grade, Ag:Au ratio,
metallurgy and Au distribution.
The Gabbs Property exhibits Quartz-sulphide Au+/-Cu style mineralization, which is
characterized by quartz and pyrite as its main sulphide. Quenched, very fine pyrite locally
exhibits difficult metallurgy while coarser sulphides are typically associated with near surface
supergene Au enrichment.
Geophysical surveys can help identify certain deposit characteristics. Gravity surveys are
designed to find geological structures and differences in subsurface density. Induced polarization
surveys are designed to find subsurface material, such as ore or alteration zones. The phyllic
alteration present at the North Sullivan area should give high chargeability response in an IP
survey. The geophysical surveys produce anomalous zones which can be tested by drilling.
A geochemical soil survey is proposed for the epithermal Car Body area. The survey involves the
collection of soil samples, identifying anomalous areas with the aim of tracing the anomaly back
to the source.
An outline of the planned work can be found in section 26.0.

9.0 EXPLORATION
Richard Jemielita visited the property and examined drill core, maps and reports between
June 14, 2011 to June 24, 2011 (Jemielita, 2011). The recommendation for detailed field and
drill core examination of structures and lithological contacts was undertaken by Pratt and Ponce
(2011). Other recommendations, such as geophysical surveys and drillings were incorporated by
the Company and are presented in section 26.0.
In August of 2011, Warren Pratt and Miguel Ponce conducted a site visit to the Property. They
spent 7 days logging core from the Sullivan, Gold Ledge, Lucky Strike and Car Body showings.
An additional 7 days were spent mapping at Sullivan, Gold Ledge and Lucky Strike. Miguel
Ponce spent an additional 4 days at Car Body and Lucky Strike.
The objective of the visit was to assess structural controls on porphyry and epithermal gold-
copper mineralization on the Property. Recommendations include geophysical targets as well as
drilling and geochemical surveys which were incorporated by the Company into future
exploration plans and are presented in section 26.0.
For a discussion of exploration prior to St. Vincent‘s acquisition of the property in 2010, see

10.0 DRILLING
The Company completed a 7,875 feet (2,400 metres) drilling program consisting of 10 RC holes
in March-April of 2011. The goal of this drilling was to expand the area of known mineralization
at the Lucky Strike area (6 holes) and test IP anomalies (4 holes) identified by previous owner,
Newcrest. Overall the drilling program was a success as 7 of 10 holes encountered at least some
gold mineralization. All of the samples were analyzed at the ALS Chemex laboratories in Reno
and Vancouver after quality assurance/quality control (QA/QC) protocol was followed using
geochemical standards, blank standards, and pulp replicate samples (duplicates), and
randomization of the submittal prior to sample preparation and analysis by a third-party
laboratory. Highlights of the three most interesting holes (SVM-4, SVM-5 and SVM-6) are
below: SVM-4 and SVM-5 extended the mineralization 2,000 feet (610 metres) at Lucky Strike
and SVM-6 encountered mineralization in at new area identified by an IP anomaly south of the
Sullivan mineralized zone. (St. Vincent in-house company correspondence 2011). A summary of
significant intersections from the 2011 drill program are summarized on Table 10.1 and the
borehole locations are presented on Figure 10.1.
P&E is not aware of any drilling, sampling, or recovery factors that could materially impact the
accuracy and reliability of the results.

11.0 SAMPLE PREPARATION, ANALYSES, & SECURITY
There is no drilling or sampling work being conducted on the Gabbs Property at the present time.
The following section summarizes the previous sample preparation, analyses, and security
undertaken on the Property during the April 2011 conducted by the Company and by Newcrest
as detailed in Maxlow (2009).
Sample procedures followed industry standards. Particular attention was paid to checking and
verifying the recording of sample data as compared to the actual samples on a daily basis to
ensure all numbering sequences and samples were correct. Following the core logging, sample
boxes were marked for sampling and moved to a secured sample room. Following sampling, all
core boxes were stored in consecutive order in secured areas adjacent to the logging and
sampling rooms.
Newcrest core drilling: core was boxed on site by drillers and picked up every 1-2 days by
Newcrest personnel and stored in a secure location until it was logged. Core was cut with a core
saw on 5 foot intervals (1.52 m) for the first phase of drilling (SD-1 through SD-13 and GD-1
and GD-2) and 2 m intervals for the remainder of the core holes (SRD-15, SD-16 through SD-
21; and GD-3 through GD-6). Samples were stored in a secured sample room prior to being
packed in rice bags.
Newcrest RC drilling: samples were bagged on the drill site, sampled on 5 foot (1.52 meter)
intervals, supervised at all times by a Newcrest geologist for sample accuracy (footage
numbering, sample quality, etc.). Samples were picked up from the drill site by the lab
(ALS/Chemex for G-1 through G-39; Inspectorate for G-40 through G-55, SR-1 through SR-5,
and SRD-15 and SRD-15).
St. Vincent RC drilling: samples were bagged on the drill site, sampled on 5 foot (1.52 meter)
intervals, supervised at all times by a St. Vincent representative for sample accuracy. Samples
were moved by St. Vincent personnel at the end of each day to a location on the property for
pickup by a representative of Shea Clark Smith.
The QA/QC procedures for 2011 drill program were set out by Shea Clark Smith who
independently prepared the samples for analysis and inserted standards, blanks and duplicates
into the sampling stream. Approximately 5% of the samples submitted were QA/QC standards.
The samples were submitted to ALS Chemex‘s laboratory in Reno Nevada.
ALS Chemex is an independent, internationally recognized minerals testing laboratory, operating
in 16 countries and the Reno location is individually certified to ISO 9001:2008 standards and
has received accreditation to ISO/IEC 17025:2005 from the Standards Council of Canada for
Fire Assay Au by Atomic Absorption.
The 2004 and 2006 drill program used non-certified gold standards, while the 2006-2007 and
subsequent drill programs used gold and copper certified standards. All Newcrest drill programs
included the insertion of pulp standards and blanks into the sample stream. Blanks made from
decorative landscaping rock (marble or scoria) were inserted into the sampling program to test
for contamination at the laboratory. Coarse nugget gold was suspected by Placer due to poor
reproducibility of gold grades during drilling in the Car Body area. Due to this ‗nugget effect,‘
the 2004 and 2006 RC drill programs used a centre-return hammer that collected 100% of the
drill sample. Samples were collected on 0.76 m intervals and combined at ALS Chemex‘ lab into
P&E Mining Consultants Inc. Page 49 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
1.52 m intervals for analysis. At least 10% of the samples sent for analysis were control samples
(Au standard pulps or blanks). A program of check assays was completed on the original pulps,
including 213 check assays of 185 intervals. 8 samples over 2 g/t Au were metallic screened.
The 2006-2007 drill programs used a minimum of 10% control samples (10% Au-Cu standard
pulps, 2% blanks.) In 2006, Newcrest switched labs from ALS Chemex to Inspectorate America.
Inspectorate Group has locations in over 100 countries, with eight Exploration & Mining Service
(EMS) hub laboratories around the world. In North America the Sparks (Reno) lab is ISO
9001:2008 certified. The lab participates in round robin testing, such as CanMet, and hires BC
Certified Assayers, experienced technicians and chemists to complete all analytical work.
Standard gold or copper values falling outside an 80%-120% accepted value range were flagged
and, in extreme cases, were re-analyzed for all samples falling halfway between inserted control
samples on either side of the unacceptable standard. All 2006-2007 drilling utilised diamond
drilling coring rigs, the drill core, from which was cut with a water-cooled core saw. Half cores
were sampled and the other half was retained. No quarter core re-split or re-assay was
performed; however, re-split and pulp re-assays were performed where standard values fell
outside the accepted range.
The 2008 drill program utilized core and RC drilling. QC procedures for core were similar to
those used for the 2006-2007 drilling, except a minimum 5% control sample rate was used (5%
Au-Cu standard pulps, 2% blanks). Sampling for RC drilling was done utilizing a rotary wet
splitter, collecting an average 10.5 kg sample. Control samples were inserted with a minimum of
5% controls (5% Au-Cu standard pulps, 2% blanks). Rig duplicate samples were collected for
RC drilling on an average of 2% of the drill samples.
11.1 CONCLUSIONS
P&E feels that the sample preparation, security, and analytical procedures were adequate for the
intended purposes.

12.0 DATA VERIFICATION
12.1 SITE VISIT AND INDEPENDENT SAMPLING
Mr. Fred Brown, CPG, visited the Gabbs Project from May 31 to June 2, 2011 for the purpose of
a site visit and completing an independent verification sampling program. The core from the
Project was examined and nineteen samples were taken in eleven holes by taking the remaining
half-core in the box. An effort was made to sample a range of grades.
At no time were any employees of St. Vincent advised as to the identification of the samples to
be chosen during the visit.
The samples were selected by Mr. Brown, and placed into sample bags which were sealed with
tape and placed in a rice bag.
The samples were brought by Mr. Brown to ALS Minerals Laboratory, (―ALS‖) in Reno,
Nevada for analysis.
ALS Minerals has developed and implemented at each of its locations a Quality Management
System (―QMS‖) designed to ensure the production of consistently reliable data. The system
covers all laboratory activities and takes into consideration the requirements of ISO standards.
The QMS operates under global and regional Quality Control (―QC‖) teams responsible for the
execution and monitoring of the Quality Assurance (―QA‖) and Quality Control programs in
each department, on a regular basis. Audited both internally and by outside parties, these
programs include, but are not limited to, proficiency testing of a variety of parameters, ensuring
that all key methods have standard operating procedures (―SOPs‖) that are in place and being
followed properly, and ensuring that quality control standards are producing consistent results.
ALS maintains ISO registrations and accreditations. ISO registration and accreditation provides
independent verification that a QMS is in operation at the location in question. Most ALS
Minerals laboratories are registered or are pending registration to ISO 9001:2008, and a number
of analytical facilities have received ISO 17025 accreditations for specific laboratory procedures.
Gold samples were fire assayed and analyzed using ICP finish. Copper was digested using four
acid with an ICP analysis.
A comparison of the results is presented in Figure 12.1 and Figure 12.2.

12.2 NEWCREST MINING QUALITY ASSURANCE/QUALITY CONTROL REVIEW
A report dated March 2009 authored by Roger Jones of the Minerals Division of Newcrest
Mining presented the results of an examination of the Gabbs Project QA/QC data from four
Newcrest drilling programs, one soil sampling program and a drilling program carried out prior
to Newcrest‘s involvement in the project. The Newcrest programs were carried out in 2004,
2006, 2006-2007 and 2008.
Two laboratories were used, ALS-Chemex for the 2004 and 2006 programs and Inspectorate for
the 2006-2007 and 2008 programs. During the first two programs, samples were analysed for
gold only. In the last two programs there were also analyses for copper.

A summary of Mr. Jones‘ conclusions is presented below.
“Several issues have emerged during the study.
Given enough assays, means for gold standards converge on the preferred value but individual
results are unreliable. The CRMs have been shown to be homogeneous (although this may not
apply to the Newcrest control samples) suggesting that there are precision issues at the
laboratories. Inspectorate appears to be worse than ALS-Chemex (28% and 18% out of control
results respectively).
Recommendation (immediate) – because individual results are likely to be unreliable, resource
calculation blocks should be large enough to include sufficient samples to reduce the variance
due to this imprecision. Geostatistical examination is indicated.
Median bias figures for the drilling programs are acceptable at -3.3%, -2.3%, +1.8% and -1.3%
for gold in the 2004, 2006, 2006-2007 and 2008 programs respectively. Copper median bias is
significantly worse at +8.1% and +4.5% for 2006-2007 and 2008 respectively.
Some jobs show a consistent bias over and above the average bias.
Recommendation (future work) – routinely examine data sets for this job-scale bias and take the
issue up with the laboratory at the time should the bias become excessive in either amplitude or
duration. This will require that a control chart be kept up to date.
Copper results for the standards are worse than gold results. Three in four results were outside
the preferred value ± 2 standard deviation limits. In fairness, two of the standards are gold
standards and the copper results have not been proven to be homogeneous to the same extent
and do not have certified copper values. Others (including all the standards used in the
2008 drilling) are copper-gold standards in which the copper concentration has been shown to
be homogeneous and has been certified.
Recommendation (immediate) - These results should be brought to the attention of Inspectorate.
Depending on their response, consideration should be given to changing laboratories if there are
alternatives available.
Results for the highest grade copper standard (certified value 1.55% Cu) are consistently
overestimated by 20-30%. Only three times in 130 assays did Inspectorate report results for this
standard inside the certified value ± 2 standard deviation limits. No other laboratory analysed
standard 54Pa in this project. From these facts it appears that the few samples reporting in
excess of 1% copper (the lowest grade at which this assay method is used) may be 20+% high.
This is a copper-gold standard and has a certified value for copper.
Screen (metallics) fire assays show that there is a coarse gold problem at Car Body. On average
55% of the gold reported in the coarse 6% of the sample. Duplicate fire assays of the passing
fraction also suggested a lack of precision in that fraction. Other prospects also show some
evidence of coarse gold problems.
Recommendation (future work) – Gold particle size distribution studies should be carried out.
Initially this could be a statistical study but mineralogical studies are likely to be necessary in
P&E Mining Consultants Inc. Page 53 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
the near future. Results from existing replicates are not suitable because of the laboratory
imprecision.
Precision is difficult to estimate because there have been very few routine field splits or pulp
splits analysed in the same batch as the original sample. Both pulp and coarse splits done at a
later time show very poor precision, with an underlying precision generally no better than about
±50% at the 95% CL. There are likely to be a number of sources of this poor precision including
coarse gold problems, poor laboratory precision and possibly inadequate sample preparation
(although this has not been established beyond the existence of a nugget problem).
Recommendation (future work) – require size analysis for a minimum of 2% of samples,
including the first sample of every batch. Results must be reported. Until proven to be excessive,
the standard should be 95% passing 75um. If any sample fails the sample is to be re-pulverised
and one in every three samples between the failed sample and the last passing sample is to have
a size analysis carried out as well. In the event of further failures in that group all samples
between a failed sample and the last passing sample are to have a size analysis carried out.
Recommendation (all work) – at least 5% of all samples should be replicated at the earliest
possible stage (i.e. at the first mass reduction stage) and reanalysed in the same batch as the
original.
Recommendation (future work) – a sample preparation orientation study should be carried out
before any further drilling to determine minimum appropriate standards for this project. If
current standards are as rigorous as can be expected then random samples should be retrieved
and sizing analysis carried out to ensure that the laboratory is complying with requirements.”
P&E completed a detailed review of the Newcrest report and the accompanying data and agreed
with the conclusions. There were many issues outlined, particularly with the certified reference
materials and precision at the pulp level and recommendations were made to address the issues.
12.3 ST. VINCENT QUALITY CONTROL REVIEW
St. Vincent completed 10 RC holes (7,875 total feet) in the vicinity of the Sullivan and Lucky
Strike deposits at the Gabbs Project, Nevada in March - April, 2011. Previous work in this
project area by Newcrest Mining encountered quality control/quality assurance (QA/QC)
problems due to nuggety gold at the Car Body deposit, and due to various laboratory prep and
analysis issues. To address these issues, a quality assurance/quality control (QA/QC) protocol
was followed by St. Vincent, involving the use of geochemical standards, blank standards, and
pulp replicate samples (duplicates), and randomization of the submittal prior to sample
preparation and analysis. Additionally, a third-party prep lab (MEG Labs, Carson City, Nevada)
was used to effectively blind QA/QC samples from the assay laboratory. Mr. Shea Clark Smith
of Minerals Exploration & Environmental Geochemistry of Reno, NV was retained by St.
Vincent to outline, implement and monitor the quality control program. A report by Mr. Smith,
dated June 15, 2011 was reviewed by P&E, as well as all raw data in Excel format.
The procedures for the QC program are presented in this section and are a direct extract from
Mr. Smith‘s report.
P&E Mining Consultants Inc. Page 54 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
“Sample Preparation
All samples were prepared at MEG Labs with the following minimum requirements:
Dry weight of each sample to account for variable recovery at the drill rig.
Randomization of the samples that comprise one hole prior to sample
preparation.
Initial crushing of the entire sample to 90% pass 1600um (10 mesh) with gravel
wash between each sample.
Riffle split to 250 grams.
Pulverize 250 grams to 90% pass 75um (200 mesh) with barren sand wash
between each sample.
12.4 QA/QC SAMPLES
QA/QC samples were identified as “QAQC 1, QAQC 2, QAQC 3” … etc. The contents were
blind to the assay lab, including: 1) certified standards of known Au, Ag, Cu, and Mo
concentration; 2) prep-blank standards that went through the sample preparation circuit; and 3)
pulp duplicates that were made from splits in the preparation laboratory. Certified standards are
in the analytical stream to measure the accuracy of the data, while prep duplicates measure the
precision of the data. Prep-blanks test for background contamination and contamination from
previous samples. All of these are vital monitors of the sample preparation and analytical
process.
QA/QC samples were placed in the submittal at irregular intervals, and at a rate of
approximately one for every 20 samples.
Additionally, the down-hole sample order was randomized prior to sample preparation and
analysis. This procedure is proven to be one of the most effective ways of revealing systematic
error, the idea for which was first introduced by A.T. Miesch (CIM Special Volume 11, p. 582-
584, 1982). Systematic error results from repetitive procedures during sample preparation and
analysis. Patterns in plots of the randomized data reveal preparation issues such as (but not
limited to) carry over from contaminated equipment and mis-calibration during assay.
Certified Standards & Blanks
The following standards and blanks were used for this project. The 95% Confidence interval is
indicated for certified elements.
MEG-Prep Blank: about 0.005 ppm Au
MEG-S106011X (MEG-Mo-1) 95% Confidence = 0.195-0.246 Mo
MEG-S108004X 0.544 ppm Au, 0.0215% Cu: 95% Confidence = 0.401-0.688 Au;
0.018 – 0.025 % Cu
MEG-S108005X 0.432 ppm Au, 0.414% Cu: 95% Confidence = 0.366-0.497 Au;
0.35- 0.48 % Cu
P&E Mining Consultants Inc. Page 55 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
12.5 ASSAY METHODS
Analysis and assay work was done at ALS Minerals. Gold assays were done in Reno, while
multi-element methods were done in Vancouver using the following codes:
Gold: Au-AA23 (30g/FA/AAS), Overlimits = Au-GRA21
Copper & Molybdenum: ME-ICP61 (4-acid digestion)”
P&E obtained the raw data in Excel format from the St. Vincent drill program. An examination
of the performance of the two certified reference materials was completed, as well as the blank
material.
There were 17 data points for standard MEG S108004X for gold and copper. P&E used +/- 2
standard deviations from the mean for the warning limits and +/- 3 standard deviations from the
mean for the tolerance limits. All 17 data points fell within the warning limits, indicating
acceptable accuracy.
There were 18 data points for standard MEG S108005X for gold and copper. All but one data
point remained within + 2 standard deviations from the mean for Au, however 100% of the data
points were above the mean indicating bias at the lab. All data points for copper remained within
+/- 2 standard deviations from the mean.
There were ten blank samples analyzed and all returned very low values, indicating no
contamination at the prep level.
P&E declares the data acquired and analyzed by St. Vincent to be of sufficient quality for use in
a resource estimate.

13.0 MINERAL PROCESSING & METALLURGICAL TESTING
St. Vincent has not conducted any mineral processing or metallurgical testing on the Gabbs
Property.
In the 1980s and 90s, Cyprus, Placer, Gwalia and Arimetco conducted limited testing of the
Sullivan ore for direct cyanidation, flotation and two-stage leaching. Results from these tests
were varied and rather inconclusive. P&E has not examined this data in detail, although a brief
summary of the historical metallurgical testing and mineral processing work that was performed
is provided in the history section 6.6 of this Report. Please see Table 6.5, Summary of
Metallurgical Studies, in Section 6.8.

14.0 MINERAL RESOURCE ESTIMATES
14.1 INTRODUCTION
The Mineral Resource estimate presented herein is reported in accordance with the Canadian
Securities Administrators‘ NI 43-101 and has been estimated in conformity with generally
accepted CIM ―Estimation of Mineral Resource and Mineral Reserves Best Practices‖
guidelines. Mineral Resources are not mineral reserves and do not have demonstrated economic
viability. There is no guarantee that all or any part of the Mineral Resource will be converted into
mineral reserve. Confidence in the estimate of Inferred Mineral Resources is insufficient to allow
the meaningful application of technical and economic parameters or to enable an evaluation of
economic viability worthy of public disclosure. Mineral Resources may be affected by further
infill and exploration drilling that may result in increases or decreases in subsequent Mineral
Resource estimates
All Mineral Resource estimation work reported herein was carried out under the supervision of
Fred H Brown, CPG, an independent Qualified Person under NI 43-101 regulations, from
information and data supplied by St. Vincent. The effective date of this estimate is December 1,
2011. A draft copy of this report was reviewed by St. Vincent Minerals St. Vincent for factual
errors.
Mineral Resource modeling and estimation were carried out using the commercially available
Gemcom GEMSTM
and Snowden SupervisorTM
software programs.
14.2 PREVIOUS RESOURCE ESTIMATES
To P&E‘s knowledge no previous public Mineral Resource disclosure has been made for the
Gabbs Property.
14.3 DATA SUPPLIED
All drilling and sampling data were supplied by St. Vincent in digital format. The database as
implemented by P&E contains 494 drillhole records, consisting of 397 ―historical‖ drillholes, 87
drillholes completed by Newcrest as part of a well-documented exploration program at the
Gabbs Property, and 10 RC drillholes recently completed by St. Vincent (Table 14.1).
TABLE 14.1
DATABASE SUMMARY
Type Record Count Total Metres
Historical 397 37,219.8
Newcrest 87 24,764.8
St. Vincent 10 2,400.3
Total 494 64,384.9
P&E notes that the historical drillholes do not meet NI 43-101 and CIM guidelines for the public
reporting of a Mineral Resource. Historical drillholes were therefore used only to define the
extent of the mineralized deposits, and historical assay grades were not incorporated into the
Mineral Resource estimate.
P&E Mining Consultants Inc. Page 58 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
14.4 DATABASE VALIDATION
Industry standard validation checks were completed on the supplied databases. P&E typically
validates a Mineral Resource database by checking for inconsistencies in naming conventions or
analytical units, duplicate entries, interval, length or distance values less than or equal to zero,
blank or zero-value assay results, out-of-sequence intervals, intervals or distances greater than
the reported drill hole length, inappropriate collar locations, and missing interval and coordinate
fields. No significant validation errors were noted.
As a further check on the supplied drillhole database, P&E recompiled Newcrest and St. Vincent
assay data from the original assay certificates. P&E believes that the data are suitable for Mineral
Resource estimation.
14.5 DOMAIN MODELING
Four distinct deposits have been identified at the Gabbs Project: the Sullivan, Car Body, Gold
Ledge and Lucky Strike. A mineralization domain was modeled for each individual deposit,
based on reasonably continuous reported drillhole assay grades greater than or equal to 0.20 g/t
Au (Figure 14.1). Using the supplied lithological and mineralogical data, an oxide/non-oxide
surface was then modeled across the property. Based on the modeled oxide surface the defined
mineralization domains were then split into upper oxide and lower non-oxide sub-domains. The
resulting domains were used for rock coding, statistical analysis and compositing limits. For the
Sullivan deposit P&E notes that based on historical drilling results the base of the Mineral
Resource is not well defined.
P&E notes that there is additional mineralization indicated by drilling results that is not
encapsulated by the modeled domains. For example, drillholes G-53 and G-54 suggest an
additional near-surface oxide exploration target not associated with the four deposits. In addition,
drillhole G-13 reported a high-grade Au intersection over twenty metres in length, which was not
duplicated by drillhole GD-1, which twins G-13. These assays grades were not incorporated into
this Mineral Resource estimate.

14.6 COMPOSITING
Assay sample lengths for the Newcrest and St. Vincent drillholes range from 0.015 m to 3.05 m,
with an average sample length of 1.52 m. A total of 84% of the samples have a sample length of
1.60 m, and an additional 10% of the samples have a sample length of 2.00 m (Figure 14.2). In
order to ensure equal sample support a compositing length of 2.00 m was therefore selected for
use for Mineral Resource estimation.
Figure 14.2 Assay sample lengths for Newcrest and St. Vincent data
Length-weighted composites were calculated within the defined sub-domains for Au and Cu.
The compositing process started at the first point of intersection between the drillhole and the
domain intersected, and halted upon exit from the domain wireframe. The wireframes that
represented the interpreted domains were also used to back-tag a rock code field into the
drillhole workspace. Assays and composites were assigned a domain rock code value based on
the domain wireframe that the interval midpoint fell within. A nominal grade of 0.001 g/t was
used to populate a small number of un-sampled intervals. Composites that were less than 0.50 m

The composite data were then exported to extraction files for grade estimation.
14.7 COMPOSITE SUMMARY STATISTICS
P&E generated summary statistics for 2,828 composite samples from the defined mineralization
domains (Table 14.2, Table 14.3 and Table 14.4).

Examination of grades trends across the oxide boundary indicate little change in Cu grade,
combined with a reduction in grade for Au (Figure 14.3). In addition, there also appears to be a
moderate degree of correlation between Au and Cu composite grades.

14.8 TREATMENT OF EXTREME VALUES
The presence of high-grade outliers for the composite data was evaluated by a combination of
decile analysis and review of probability plots. Decile analysis results indicate that at Sullivan
28% of the contained oxide Au is from the last decile, and 56% of the contained Non-Oxide Au
(Figure 14.4). A capping value of 5.00 g/t was applied to Au grades and 9,000 ppm to Cu grades,
capping two Au composites and one Cu composite.

14.9 BLOCK MODEL
An orthogonal block model was established across the property with the block model limits
selected so as to cover the extent of the mineralized domains, and the block size reflecting the
scattered and irregular drillhole spacing (Table 14.5). The block model consists of separate
models for estimated grade, rock code, percent, density and classification attributes. A percent
block model was used to accurately represent the volume and tonnage that was contained within
the constraining grade domains. As a result, the Mineral Resource boundaries were properly

14.10 ESTIMATION & CLASSIFICATION
A bulk specific gravity value of 2.70 t/m3 was used for the country rock and of 2.50 t/m
3 for the
oxides, as no comprehensive density information is available. This value corresponds to the
monzonite density used by Newcrest. The average specific gravity of the nineteen P&E check
samples is 2.68 t/m3.
Block grades for Au were estimated using isotropic inverse distance cubed (ID3) linear
weighting of capped composites, and block grades for Cu were estimated using isotropic inverse
distance squared (ID2) linear weighting of capped composites. Between three and twelve
composites from two or more drillholes were required for block estimation; in addition,
composite values were also restricted to the Newcrest and St. Vincent drillhole data. The
modeled oxide surface was treated as a hard boundary for Au estimation and as a soft boundary
for Cu estimation.
P&E believes that the current level of information available is sufficient to classify the Mineral
Resource as Inferred. Mineral Resources were classified in accordance with guidelines
established by the Canadian Institute of Mining, Metallurgy and Petroleum:
Inferred Mineral Resource: ―An ‗Inferred Mineral Resource‘ is that part of a Mineral Resource
for which quantity and grade or quality can be estimated on the basis of geological evidence and
limited sampling and reasonably assumed, but not verified, geological and grade continuity. The
estimate is based on limited information and sampling gathered through appropriate techniques
from locations such as outcrops, trenches, pits, workings and drillholes.‖
In order to reach an Indicated Mineral Resource level of confidence for the Gabbs Project, P&E
recommends the following:
Diamond drillholes to define the vertical extent of the Sullivan deposit;
Systematic drilling on a grid of approximately 150 ft x 150 ft across the deposits;
Collection of specific gravity data;
Improved definition of the oxide transitional boundary, possibly from diamond
drillhole core;
Survey of all recent and future drillhole collars by a licensed surveyor;
Diamond drillhole core from across the structural fabric to define sub-vertical
high-grade fracture systems.

14.11 MINERAL RESOURCE ESTIMATE
NI 43-101 requires that a Mineral Resource demonstrate economic potential. In order to meet
this criterion, P&E generated conceptual pit shells and calculated separate cut-offs for the oxide
and non-oxide domains, based on the listed economic parameters (Table 14.6). Economic
parameters were derived by P&E from general knowledge of similar projects, and in particular
from Ewert et. al (2011). Commodity prices are based on the two year trailing average as of
November 30, 2011.

(1) Mineral Resources which are not mineral reserves do not have demonstrated economic viability. The
estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title,
taxation, socio-political, marketing, or other relevant issues.
(2) The quantity and grade of reported Inferred Mineral Resources are uncertain in nature and there has been
insufficient exploration to define these Inferred Mineral Resources as an Indicated or Measured Mineral
Resource, and it is uncertain if further exploration will result in upgrading them to an Indicated or
Measured Mineral Resource category.

$1,350.00/oz were used along with an oxide process cost of $6.50/tonne, a sulphide process cost of
$9.50/tonne and G&A costs of $2.25/tonne.
(9) An oxide Au recovery of 50% and a sulphide Au recovery of 90% were used. No Cu recovery was assumed
for the oxide.
(10) Resources were estimated within an optimized pit shell utilizing pit slopes of 45 degrees and mining costs of
$1.50/tonne of rock.
(11) The conversion factor for AuEq is: AuEq=Au+Cu*1.67/10,000.
14.12 VALIDATION
The block model was validated visually by the inspection of successive section lines in order to
confirm that the model correctly reflects the distribution of high-grade and low-grade samples.
Contained volumes and calculated tonnage for each domain solid were also compared to
estimated tonnage per domain at a zero cut-off (Table 14.8). No discrepancies were noted.

18.0 PROJECT INFRASTRUCTURE
A well maintained gravel road bisects the property and a major power transmission line crosses
the project west of the Sullivan Mine area. Groundwater on the property is sufficient in places to
allow drilling of a water well once it is permitted. Limited logistical support can be found in the
town of Gabbs, though most service and supplies can be sourced from the town of Fallon,
Nevada, located approximately 75 mi northwest of the site or the town of Hawthorne which is
55 mi west-southwest of the site. Fallon has a population of 8,525.

IMPACT
A water permit was obtained for the Gabbs Property. According to the State of Nevada‘s
Division of Water Permit website, Permit #50803 was held by the Omega Resource Company
for the Sullivan Project, and the specified use is for milling and mining. Newcrest acquired the
water permit along with the Sullivan property from Arimetco Inc. After field investigation in
2007, it was determined that either no well was drilled or it was abandoned. Due to the well‘s
location, Newcrest withdrew its interest in maintaining and perfecting a well. The permit‘s
current status is listed as ―Withdrawn‖.

23.0 ADJACENT PROPERTIES
The information contained in this section is summarized from Economic Geology report on the
Paradise Peak property prepared by Sillitoe and Larson (1994).
At the Paradise Peak Mine, the high sulphidation ore is hosted by strata-bound bodies of
pervasively silicified, welded ash-flow tuff. The highest precious metal values were found in
hydrothermal breccias which cut silicified tuff and, at the Paradise Peak deposit, also overlying
andesite flows and felsic tuffs altered to a quartz-alunite assemblage.
A lower andesite sequence is the host for a large zone of low-grade porphyry style gold
mineralization. This andesite sequence is located beneath the mineralized tuff horizons. Gold is
present in a quartz veinlet stockwork cutting sericitized andesite flows, which is inferred to be
intruded at depth by a porphyry stock.
Three of the high sulphidation ore bodies were believed to have been a sole deposit prior to an
episode of detachment faulting which took place after steep, normal faulting and precious metal
mineralization were complete.
High sulphidation mineralization in the east lobe of the Paradise Peak deposit and at Ketchup
Hill lies beneath the base of oxidation and consists of refractory sulphidic material. Sulphides
comprise 10 to 90 %, by volume, of the unoxidized material and, after oxidation, produced the
friable, powdery ore common in the ore bodies. Weathering resulted in very localized
redistribution of silver and gold. Hypogene oxidation was not recognized.
The reader is cautioned that the Qualified Persons have been unable to verify the information in
this section and such information is not necessarily indicative of the mineralization on the
property that is the subject of this Report.

25.0 INTERPRETATION & CONCLUSIONS
25.1 INTERPRETATION
Gold-rich porphyry deposits have close spatial, temporal and genetic relationships with high
sulphidation epithermal gold deposits. This is clearly demonstrated at Paradise Peak where high
sulphidation epithermal gold-silver-mercury mineralization and porphyry gold style
mineralization (East Zone) occur in close proximity (Sillitoe and Lorson, 1994).
The Gabbs Project contains at least three separate Au-Cu porphyry prospects and one epithermal
gold prospect. Their close proximity to each other suggests that they either share a common
source which has possibly been structurally dismembered from a once continuous system, or that
multiple intrusive centers exist.
Mineralization in the Sullivan, Lucky Strike, and Gold Ledge south areas appears to be
predominantly porphyry gold-copper style mineralization. Gold and copper mineralization is
associated with felsic intrusive rocks ranging in composition from monzonite to quartz
monzonite to quartz diorite. Gold and copper mineralization extends into adjacent gabbro and
pyroxenite, and to a much lesser extent into the Triassic volcano-sedimentary package.
25.2 CONCLUSIONS
The Gabbs Project porphyry bodies are bounded and cut by ductile shear zones and associated
with deep, mesothermal fault/shear hosted quartz veins both characteristic of relatively deep
crustal levels. In an idealised porphyry gold-copper deposit the gold and copper mineralized zone
is centred on a porphyry stock characterised by potassic-alteration with disseminated and
stockwork magnetite-chalcopyrite mineralization surrounded by an annular zone of pyrite rich
phyllic alteration giving way outwards to barren propylitic alteration. Porphyry gold-copper-
molybdenum mineralization at the Property lacks clear concentric zonation of alteration minerals
etc., so it does not appear to be a classical zoned porphyry system (Lowell and Guilbert, 1970).
The monzonite porphyries at the Property may be simple sills or dikes but the schist/shear fabric
at their contacts suggests at least some degree of tectonic emplacement so they could be
dismembered slices of a larger, as yet undiscovered, gold-copper-molybdenum mineralized
porphyry stock.
The corridor that links Sullivan, Gold Ledge, and Kona (an area of future exploration interest
located to the west of Gold Ledge) is of paramount interest and should be tested with IP and deep
RC holes. These drill holes should be steeply inclined towards the north. It is likely that any
porphyries encountered will strike almost E-W and dip moderately or gently south (as at Sullivan
and Gold Ledge). It is recommended to step out from known porphyry occurrences, starting on
the east side of Gold Ledge, where porphyry may be concealed beneath thin Tertiary cover (Pratt
& Ponce, 2011).
Structural geology, geophysics and drilling are likely to be effective exploration techniques for
locating additional mineralization. If a source porphyry gold-copper mineralized stock exists at
the Gabbs Property then it is likely to occur down dip of the monzonite porphyry ―sills.‖
Geophysics and follow-up drilling in this direction (i.e. southwest of Sullivan and southeast of
Lucky Strike, would appear warranted), (Pratt & Ponce, 2011).
P&E Mining Consultants Inc. Page 80 of 89
St. Vincent Minerals Inc. Gabbs Au-Cu Property Report No. 220
Mineralization at Car Body is disseminated gold associated with quartz-sericite-pyrite- (phyllic-)
alteration. Mineralization is hosted by the same Tertiary andesite-rhyolite volcanic intrusive
sequence as the nearby Paradise Peak epithermal-porphyry gold (silver-mercury) deposits. These
deposits may be the same age and are, perhaps, genetically related. Car Body may represent a
deep/marginal alteration and mineral zone related to Paradise Peak.
At Car Body, careful logging of the volcanic stratigraphy and closely spaced diamond drilling
are required. Drilling should gradually work away from known areas of high grade. This is
probably the best way to build a reliable resource until geological controls are better understood.

26.0 RECOMMENDATIONS
A two phase exploration program is proposed for the Gabbs Property.
26.1 PHASE I EXPLORATION PROGRAM
The structural study will complement the data collected by Newcrest and determine if the recent
geologic and resource modeling interpretation that mineralization at Sullivan may be structurally
controlled within a low-angle (potentially thrust) fault zone is a valid assumption.
The metallogenic study will help determine the gold-copper mineralization genetic relationships
from the various mineralized zones. Newcrest had been pursuing the theory of a porphyry related
mineralization model. Analysis of existing data sets (geology, alteration and geochemistry) will
provide new insights to the mineralization and allow targeting for testing for new mineralized
areas on the property.
At the Lucky Strike the drilling will further define and test the copper-gold mineralization. At the
Lucky Strike one or two of the previous holes should be twinned within 10 metres. The new
holes should be assayed using the same methods as the previous holes but selected section or
samples should employ a total cyanide digestion. These holes will provide grade comparison and
help determine if modifications to the sample process technique are required.
At Sullivan drilling will test geophysical anomalies defined by the Newcrest work and provide
structural data to determine if the mineralization is structurally controlled.
St. Vincent should continue to utilize the QA/QC program initialized by Newcrest and look into
the QA/QC recommendations by Jones (2009).
