1. SUMMARY
This report describes a program of reverse circulation drilling that was conducted 80 km north of Kirkland Lake, Ontario, on the West Lake Abitibi Property which is held under option by Boulder Mining Corporation. Sixteen holes were drilled on the main claim block to test the inferred western extension of the thickly overburden-covered, E-W trending, gold-fertile Lake Abitibi Deformation Zone. The locations of the drill holes were based on the assumption that the deformation zone forms the
contact between northern turbidites of the Scapa Assemblage and southern komatiites of the Stoughton - Roquemaure Assemblage and that this contact lies 3 km further north than previously thought. Two additional holes were drilled on kimberlite-suggestive aeromagnetic bullseyes on a satellite claim block further to the north.
The drilling was intended to sample both the glacial till and underlying bedrock. Sixteen holes were completed successfully, and the average depth of these holes, including about 1.5 m of bedrock, was 43.5 m. Ninety-seven till samples and two gravel samples were processed to extract their heavy mineral fraction and visually separate any gold grains and, on the satellite claims, kimberlite indicator minerals. Most of the heavy mineral concentrates and all bedrock samples were also geochemically analyzed. The project was completed on budget with total drilling, geological and laboratory costs of S96,032.67 or S138.047metre.
The contact between the turbidites and komatiites was found to be in the anticipated northerly location but this contact is unsheared, unaltered and unmineralized. Magnetic pyroxenite and nonmagnetic cherry exhalites were intersected on the northerly magnetic anomalies that were targeted as kimberlite. The chert is anomalous in chalcopyrite which could indicate proximity to volcanogenic massive sulphides.
The buried bedrock surface is relatively flat. Consequently any old, unconsolidated sediments deposited by early glaciations were left unprotected during final S SE ice flow and were replaced by younger Matheson Till, esker gravel and varved Lake Ojibway clay, silt and sand. Ice meltdown in the glacial lake led to much interlayering of the till with the other sediments. The till is also molded into large drumlins which locally rise through the clay cover and impart a S SE grain to the surface topography. Its heavy mineral fraction contains only normal background levels of gold grains, reflecting the observed infertility of the underlying bedrock. The till on the satellite claims is devoid of kimberlite indicator minerals; therefore not only the two targeted magnetic bullseyes but also any others to the north are due to lithologies other than kimberlite.
The Lake Abitibi Deformation Zone, if present on the property, must be in the traditionally accepted position on the southern boundary where a formational conductor suggestive of structurally incompetent graphitic mudstone interrupts the magnetic komatiites. All diamond drill records from this area should
be scrutinized for evidence of the deformation zone and signs of gold mineralization before contemplating any further gold exploration. Several short, weak electromagnetic anomalies near the chalcopyrite-bearing exhalites on the satellite claims should be investigated as possible volcanogenic massive sulphide targets but no further kimberlite exploration is warranted.

2. INTRODUCTION
2.1 Property Location, Access and Ownership
The West Lake Abitibi Property, which was the focus of the reverse circulation drilling program
described in this report, is 80 km north of Kirkland Lake in northeastern Ontario (Fig. 1). Geologically,
it lies in the Abitibi Subprovince (Abitibi Granite-Greenstone Belt) of the Archean-age (~2700 Ma)
Superior Province of the Canadian Shield.
The property consists of one large, 3952 ha claim block and several small satellite blocks (Fig. 2). The
main block extends westward 13 km from Northwest Bay of Lake Abitibi, the largest remnant of glacial
Lake Ojibway. It straddles the boundary between Bowyer and Marathon Townships in the north and
Galna and Moody Townships in the south. The drilling focussed on this claim block and on the nearest
satellite block, 3 km to the north in eastern Marathon Township.
The nearest towns (Fig. 3) are Iroquois Falls, 30 km to the west, and Cochrane, 60 km to the northwest.
Road access is gained from Cochrane by travelling east 54 km on Route 652, then south 17.5 km on
Abitibi Consolidated's Single Lake logging road to the abandoned CN railway line and continuing 8 km
further south to Traill Lake in Moody Township (Plan l, in pocket).
The West Lake Abitibi Property was staked by C. J. Baker, an independent consulting geologist from
Ottawa with historical prospecting experience in the Lake Abitibi area. The property is optioned to
Boulder Mining Corporation ("Boulder") of Vancouver, B. C. Boulder funded the reverse circulation
drilling program.
2.2 Project Background and Objectives
The main claim block of the West Lake Abitibi Property is thought to host the western extension of the
regional-scale, east-west trending Lake Abitibi Deformation Zone (Fig. 2). This deformation zone is
considered attractive for gold exploration because: 1) most of the major gold deposits of the Abitibi
Subprovince are hosted by similar deformation zones, notably the Destor - Porcupine Fault Zone and
Cadillac - Larder Lake Break to the south (Fig. 3) and the Casa Berardi Fault to the northeast (Pattison

et al,3 1986}^ 2) high-grade gold-quartz boulders have been identified along the Munro Esker in
Milligan Township south (glacially down-river) of the inferred fault (Ferguson and Freeman, 1978; Fig.
2), and 3) anomalous concentrations of gold grains have been identified by panning along both the
Munro and Long Point Eskers and the anomalies extend only as far north (glacially up-river) as
Northwest Bay where the deformation zone is located.
While the evidence for significant lode gold mineralization in or near the Lake Abitibi Deformation
Zone is compelling, the actual position of the fault in the area west of the lake is uncertain because the
bedrock surface is covered by glacial till and gravelly to clayey esker and Lake Ojibway sediments up to
80 m thick. Most maps, including the Ontario Geological Survey's 1992 compilation (Fig. 3), place the
fault in north-central Moody and Galna Townships, roughly coincident with the southern boundary of
the main claim block of the West Lake Abitibi Property. This position was first proposed by Pyke et al.
(1972) and follows a linear conductive zone (Fig. 4) interpreted to be the contact between northern
turbidites of the Scapa Assemblage and southern, komatiitic, mafic to ultramafic volcanics of the
Stoughton-Roquemaure Assemblage (Jackson and Fyon, 1992). On the basis of reprocessed
aeromagnetic data, however, Ayer et al. (1999) placed the fault contact 3 km further north in a non-
conductive zone near the centre of the main clam block. The reverse circulation drilling targeted this
inferred northern fault corridor.
The drilling on the satellite claims was targeted not on gold but rather on two small magnetic bullseyes
(Fig. 5) suggestive of serpentinized kimberlite pipes. The potential for kimberlite was considered high
because 1) the property lies on the northwestern extension of the Lake Timiskaming Structural Zone
(Sage, 1996) which hosts numerous kimberlite pipes in the Matheson, Kirkland Lake and New Liskeard
areas (Fig. 3), and 2) the pipes tend to be clustered at the intersections of this NW-SE trending structural
zone with the major E-W trending, gold-bearing deformation zones.
The reverse circulation drilling sampled both the till and the underlying bedrock. The till samples were
processed for gold grains and, on the satellite claims, for kimberlite indicator minerals. The bedrock
samples were used to map various geological relationships including stratigraphy, structure and
alteration as no outcrops are present on the property. This report documents the work performed and the
results obtained.

3. METHODS AND COSTS
3.1 Contractors
Overburden Drilling Management Limited ("ODM") of Nepean, Ontario chose the locations of the drill
holes and access roads, arranged the drilling contract, oversaw the drilling, logged the holes, processed
the till samples for heavy indicator minerals and interpreted the data. ODM's field geologist was Donald
Holmes. Remy Huneault supervised the sample processing, Stuart Averill logged the bedrock samples,
interpreted the data and prepared the report and Llyle Duchene produced the report and illustrations.
C.J. Baker laid out the drill sites in the field and supervised the road bulldozing work which was
performed by John Wlad St. Sons of Iroquois Falls. Heath Si Sherwood Drilling (1986) Limited of
Kirkland Lake performed the drilling and also supplied meals and accommodations at a temporary trailer
camp erected near Traill Lake. The samples were collected under ODM's direction by R. Mowat, a
resident of Wahgoshig First Nations Reserve on the south shore of Lake Abitibi. Actlabs Limited of
Ancaster, Ontario, analyzed both the bedrock samples and ODM's heavy mineral concentrates from the
till samples.
3.2 Field Procedures
The inferred shear zone that was targeted on the main claim block trends roughly E-W. It was tested
with a single traverse of drill holes but this traverse was broken into shorter, WNW-ESE trending
segments (Fig. 4; Plan 1) in order to repeatedly cross the target and efficiently map the bedrock geology.
These WNW-ESE segments are roughly normal to the final SSE ice flow (Fig. 2) that generated the
main till horizon (Matheson Till) in the area and would also intercept possible remnants of a slightly
older phase of the till that was deposited by WSW to SSW ice flow. Such till remnants could be
preserved in protective E-W trending preglacial valleys along the targeted deformation zone or in
sinkholes over kimberlite pipes (Averill and Mcclenaghan, 1994). On the northern satellite claims, a
single hole was drilled on each of the two kimberlite-suggestive magnetic anomalies.
The routes of the tractor roads to the drill holes were chosen from 1970s stereo air photos of 1:50,000
scale. Wherever possible, historical logging trails and open areas of muskeg were utilized to minimize
- 10-
vegetation damage. Timber cutting was required along only l .5 km of the 12 km long road on the main
claim block. The old railway bed and an off-branching logging trail were used to reach the northern
kimberlite targets. Although the drill holes were accurately sited from the air photos, their geographic
co-ordinates were also measured by GPS (Table l). However, hole elevations determined by OPS were
found to be very inaccurate, requiring estimates to be made from the air photos and topographic maps.
A reverse circulation drill string consists of two coaxial pipes and a tricone bit (Fig. 6). Air and water
are injected between the pipes to the bit and clay to pebble-sized sediment particles and cm-sized
cuttings of boulders and bedrock are flushed instantly through the centre pipe to surface where they are
logged (Appendix A) and bulk samples weighing 8 to 10 kg are collected. Fine silt and clay suspended
in the drill water are settled in a special tank and the water is recirculated down the drill hole. Heath SL
Sherwood's drill was mounted on a Nodwell tracked carrier for off-road mobility and was fully enclosed
for all-weather operation. Water was hauled to the drill with a smaller Go-Track carrier.
The drill holes were prefixed WLAP-02 (for West Lake Abitibi Property, 2002) and were numbered
consecutively in the sequence drilled. The samples from each hole, whether of till or bedrock, were
numbered consecutively (e.g. WLAP-02-05-01 to 22 in Hole 05).
3.3 Sample Processing and Indicator Mineral Logging Procedures
The bedrock samples were sieved to separate coarse (+2.0 mm), clean cuttings suitable for binocular
microscope logging (Appendix B) and geochemical analysis. The till samples were processed using the
procedures shown in Figure 7. All processed samples (Table 1) were tested for gold grains but only the
samples from the two drill holes on the satellite claims were tested for kimberlite indicator minerals
("KIMs").
The flow sheet of Figure 7 utilizes procedures that are designed to progressively reduce the bulk sample,
concentrate all of the heavy minerals, and finally clean and sort these minerals to simplify identification
of any indicator mineral grains. First the sample is wet screened at 2.0 mm and a -2.0 mm table
concentrate is prepared. Geological observations on the character of the sample are made during both
the screening and tabling operations (Table 2). The table concentrate is purposely large (typically 300-

500 g) and of low grade (10-30 percent heavy minerals) in order to achieve a high, 80-90 percent
recovery rate for all desired indicator minerals irrespective of their grains size or specific gravity. The
gold grains, which are mostly silt-sized, are observed at this stage with the aid of micropanning and are
counted, measured and classified as to degree of wear (i.e. distance of glacial transport; Fig. 8). Their
gold assay value is also calculated (Appendix C). For samples that are being tested for KIMs, the table
reject is reprocessed to scavenge possible unrecovered KIMs, especially the largest grains which are the
most difficult to recover.
If the heavy mineral fraction is to be geochemically analyzed for gold and base metals, the -2.0 mm table
concentrate is separated in methylene iodide at S.G. 3.32. If KIMs are targeted, the methylene iodide is
diluted with acetone to S.G. 3.20 to ensure recovery of the least dense KIM species. Undesirable
magnetite is then removed from the heavy liquid concentrate using a ferromagnetic separator. If KIMs
are being targeted, the finer, -0.25 mm grains are sieved from the nonferromagnetic heavies and the
retained 0.25-2.0 mm grains are cleansed with oxalic acid to remove limonite stains that would
otherwise impede mineral identification. The clean heavies are then sieved at 0.5 and 1.0 mm. The
0.25-0.5 mm fraction, which contains the most mineral grains, is sorted electromagnetically into strongly
^0.6 amp), moderately (0.6-0.8 amp), weakly (0.8-1.0 amp) and non-paramagnetic (5-1.0 amp) fractions
which are of simpler mineralogy, thereby easing indicator mineral logging. This logging is done by
experienced exploration geologists/mineralogists, not by technicians. These mineralogists are familiar
with all minerals in the concentrate, not just a limited suite of KIMs, and are therefore able to recognize
minerals indicative of any type of deposit and mineral textures and distribution patterns critical to
follow-up exploration. To this end, they also systematically record the major, regional heavy mineral
suite or assemblage of each sample, thereby monitoring any significant changes in the overall
provenance of the till. Any difficult mineral grains are resolved by energy dispersive x-ray spectrometry
("EDS") analysis using a scanning electron microscope ("SEM"). All indicator mineral grains, or
representative examples of larger populations of such indicators, are carefully vialed for future
reference.

3.4 Analytical Procedures
The heavy mineral concentrates of the till samples from the satellite claims were not analyzed
geochemically. The concentrates from the main claim block were analyzed for Au, As, Ag, Cu, Pb, Zn,
Ni, Cd, Mo, Mn and S. Both Au and As were determined by instrumental neutron activation (INA)
analysis using up to a 60 g (as available) aliquot with no acid digestion. The other nine elements were
determined by inductively coupled plasma/mass spectrometry (1CP/MS) on a milled 0.5 g aliquot using
aqua regia acid digestion. All bedrock samples were milled, wholly fused or partially digested as
required and analyzed by a similar IN A + ICP/MS combination for whole rock oxides plus 32 elements
including rare earths and the metals that were determined for the till concentrates.
3.5 Drill Performance and Project Costs
The work performed and/or supervised by ODM (i.e. everything except laying out the drill hole sites in
the field and clearing roads to these sites) was budgeted at 5106,615.50 (Table 3). This budget was
based on drilling 20 holes at Heath *fe Sherwood's quoted hourly contract prices assuming an average
hole depth of 40 m for a total of 800 m, a production rate of 6 m per drilling/moving hour (excluding
moving time between the two properties), 10 percent mechanical down-time, changing the tricone bit
every 60 m and processing an average of 6.5 till samples per hole. The expected cost per metre was
therefore S133.27; of this, S86.05 was allocated to Heath A Sherwood's drilling operations and camp
charges.
Eighteen holes were actually drilled. Two, Nos. 01 and 07, did not reach bedrock and were replaced by
Holes 16 and 11, respectively. The average depth of the 16 completed holes was 43.5 m (Table 1), or 11
percent deeper than forecast, for a total of 695.7 m. Twelve tricone bits were used for an average of 58
m/bit, very close to the expected 60 m. An average of 6.2 "till" samples (includes two gravel samples
from Hole 17) was processed from these holes. This is slightly below the budgeted 6.5 samples;
however, an average of 7.4 samples/hole was actually collected but in Holes 05,09,10 and 12, only the
odd-numbered samples from the upper parts of extra-thick till sections were processed. Actual
mechanical down-time was only 0.4 percent but this does not include time spent rectifying a fluid bypass
problem in the drill string that was the main reason for abandoning Holes 01 and 07. If these two

unfinished holes are excluded, average productivity was only 5.1 m per drilling/moving hour, or 15
percent below forecast. The lower productivity is not all due to the two lost holes; it also reflects the
excessive hole depth as the penetration rate of a reverse circulation drill decreases with depth. With
fewer metres drilled per hour, the cost per metre of Heath & Sherwood's drilling operations rose
significantly to S93.83 or 9 percent more than forecast, but the total project cost was kept 10 percent
below budget at S96,032.67 by reducing the number of holes drilled and till samples processed.
4. RESULTS
4.1 Bedrock Geology and Geochemistry
As expected, most of the drill holes that reached bedrock intersected either northern turbidites of the
Scapa Assemblage or southern mafic volcanics of the Stoughton - Roquemaure Assemblage (Plan l, in
pocket). Although the contact between the two assemblages is in the location predicted by Ayer et al.
(1999), it is neither sheared nor hydrothermally altered. The Scapa turbidites and Stoughton -
Roquemaure komatiites both face south (Jackson and Fyon, 1992), and komatiites are typically the
lowermost horizons of volcanic successions deposited in submarine basins. Therefore the contact
between the two assemblages is probably a normal, conformable contact.
Minor intersected lithologies include cherty exhalative sediments in Hole 18, gabbro in Hole 04,
pyroxenite in Hole 17, feldspar porphyry in Hole 08 and a Proterozoic diabase dyke in Hole 14. The
cherry sediments occur within the northern turbidites and coincide with the easternmost magnetic
bullseye that was targeted as kimberlite (Fig. 5) but the drill hole was not centered on the anomaly and
the 2.2 m drill intercept (Table l) does not contain magnetite or pyrrhotite. It does, however, contain a
thin (O.4 m; Appendix A) interval of mafic volcanics. This suggests that the cherty exhalations are
related to a volcanic event that briefly interrupted turbidite sedimentation an event that may have been
a precursor to major Stoughton - Roquemaure volcanism or residual to earlier calc-alkaline volcanism.
The gabbro and pyroxenite also occur within the turbidites and thus may have been feeder intrusions for
Stoughton - Roquemaure volcanism. The pyroxenite is responsible for the second, more westerly
magnetic bullseye that was targeted as kimberlite (Fig 5). The feldspar porphyry occurs within the
southern komatiites and may represent a feeder for younger, more evolved calc-alkaline volcanism
-21 -
higher in the volcanic pile. The porphyry coincides with a magnetic low between two magnetic diabase
dykes (Fig 4) which have the north-south trend typical of the 2454 Ma Matachewan dyke swarm
(Osmani, 1991). The diabase intersection of Hole 14 is on a similar dyke further east.
Most of the turbidite intersections are fine-grained siltstones, with greywacke occurring only in Hole 10
and as minor laminations within the siltstone of Hole 03. The siltstone cuttings vary in colour from grey
to green but their grain size is so uniform typically 0.05 mm that bedding is seldom evident. The
0.05 mm silt particles are too small for mineralogical resolution by binocular microscope but in
aggregate are relatively soft indicating that they consist mainly of saussuritized plagioclase with little
quartz. A finer silt/clay component is represented by 20-50 percent chlorite (variably sericite). Some
samples are spotted with up to 5 percent small (0.1-0.3 mm) biotite metacrysts indicating metamorphism
of the turbidites at mid-greenschist facies. The Hole 10 greywacke is a poorly sorted, fine to medium
(0.1-0.5 mm) sand with 15 percent finer-grained matrix chlorite/biotite. The sand component consists
mainly of saussuritized plagioclase plus visually similar intermediate volcanic lithic grains with only 15
percent quartz grains. Chemically the turbidites are equivalent to calc-alkaline andesite (Table 4; Fig.
9). All are well-foliated to semi-schistose but not sheared. Carbonates are generally either absent or
restricted to minor, fracture-hosted calcite. Primary pyrite (or more rarely pyrrhotite) stringers and
disseminations are often present but their maximum concentration is only l percent.
The chert of Hole 18 is a pale green-white, sugary-textured rock with a grain size of 0.05-0. l mm. It is
an impure, silty chert as it contains 5*M) chlorite/biotite and its SiCh content, although higher than that of
all other intersected lithologies except feldspar prophyry, is only 69 percent (Table 4). The most
noteworthy feature of the chert is the presence of l percent primary, disseminated to stringer pyrite
which is accompanied by 0.1 percent chalcopyrite. Two bedrock samples rather than the usual 1.5 m
sample were collected from Hole 18 (Table 1) and the sulphide mineralization extends through both
samples including the mafic volcanic interval that interrupts the chert. Sphalerite is absent but the
weakly mineralized chert could nevertheless represent an exploration cue because anomalous exhalite
beds occur near many volcanogenic massive sulphide deposits.
The mafic volcanics are dark green, variably foliated rocks with a grain size of 0. l -0.3 mm. They lack
amygdules and have the equigranular, interlocking texture typical of the unquenched central parts of
basalt flows extruded in deep submarine basins. Mineralogically they consist of subequal chlorite and

saussuritized plagioclase with <l percent visible quartz. They lack the magnetite that is typical of high-
Fe tholeiites and most are relatively enriched in MgO (Table 4, Fig. 10). In most samples, part of the
chlorite has been transformed to actinolite the equivalent of the mid-greenschist facies biotite
observed in the turbidites. Calcite and pyrite levels are even lower than in the turbidites.
The gabbro of Hole 04 has a grain size of 0.7-1.0 mm, nearly five times coarser than the mafic
volcanics. It is also significantly less mafic, containing more (3 percent versus l percent) quartz and
less (30 percent versus 50 percent) chlorite/actinolite and is more carbonatized, with 10 percent calcite.
Chemically it is equivalent to calc-alkalic andesite (Table 4, Fig. 10).
The pyroxenite of Hole 17 is a completely hydrated and carbonatized rock consisting of subequal
proportions of talc, chlorite and Fe-Mg carbonate. Originally it was probably a websterite as talc is
chemically equivalent to hydrated orthopyroxene and chlorite to hydrated clinopyroxene. The rock
contains 20 percent MgO (Table 4; Fig. 10) which is high for pyroxenite; however a peridotite protolith
is improbable because the rock contains 5 percent plagioclase and only 1-2 percent olivine-suggestive
(i.e. patchily disseminated) magnetite. This minor magnetite explains the weak, kimberlite-suggestive
magnetic signature (Fig. 5) of the pyroxenite.
The feldspar porphyry of Hole 08 is a pale grey-white, weakly foliated granitoid rock with 10 percent
coarse, l .5-4 mm plagioclase phenocrysts in a medium-grained, 0.5-1.0 m groundmass. It is a two-mica
porphyry containing 2 percent biotite/chlorite plus 5 percent muscovite and has a rather high quartz (30
percent) and SiO2 (70 percent; Table 4) content. It also contains 0.5 percent coarsely disseminated cubic
pyrite but otherwise is unaltered and unmineralized.
The Matachewan diabase intersected in Hole 14 is a massive, unmetamorphosed, diabasic-textured,
green and white rock. It consists of 60 percent fresh, unsaussuritized plagioclase and 40 percent primary
green to grey-brown clinopyroxene. The diabase also contains l percent interstitial magnetite,
explaining the linear, north-south trending aeromagnetic anomalies that trace the dyke swarm (Fig. 4).
Chemically it is equivalent to tholeiitic basalt (Table 4, Fig. 10).
In keeping with their unsheared and unaltered condition, the bedrock samples yielded only normal
background Au analyses (Table 5). The highest value is 8 ppb in the mafic volcanics of Hole 13; all
other samples yielded ^5 ppb Au. The As, Ag, Cu, Pb, Zn, Ni, Cd and Mo values are similarly low, the

reflecting the 0. l percent chalcopyrite observed in this chert, and 418 ppm Ni in the pyroxenite of Hole
17, reflecting the presence of Ni-scavenging orthopyroxene and olivine in the pyroxenite at the time of

4.2 Overburden Stratigraphy
The glacigenic sediment and surficial peat layers intersected in the drill holes are shown on Sections A-
A' to C-C1 (Figs. 11 to 13) and the section lines are shown on Plan 1.
The bedrock surface is flat to gently undulating and thus, during the final SSE ice flow event, afforded
little protection to unconsolidated sediments generated by earlier, southwesterly ice flow. Consequently
only young Matheson Till and associated esker gravel and varved Lake Ojibway clay, silt and fine sand
are present. The till typically forms a 2-10 m thick blanket over the bedrock but is locally moulded into
thicker drumlinoid ridges that rise through the clay cover and impart a SSE grain to the otherwise flat
surface topography (Plan 1). It is also variably interlayered with the clay, silt, sand and gravel,
reflecting the fact that ice meltdown and till deposition occurred in Lake Ojibway. The deep lake water
added buoyancy to the ice sheet. Instead of melting steadily northward, the ice front became mobile,
repeatedly overriding the initial till and sediment layers on the lake bottom and topping them with new,
similar layers. The texture of the individual till layers oscillates considerably from clayey to sandy
depending on the nature of the overridden sediments.
4.3 Gold Grain Counts
Most of the till samples yielded one to eight gold grains (Table 6, Appendix C). The maximum
concentration is fifteen grains and some samples yielded no gold grains. The gold grain concentration in
thick till sections does not change significantly from top to bottom (Figs. 11 to 13) and more than 90
percent of the grains are reshaped (i.e. far travelled; Fig. 8). Therefore the 0-15 grain level simply
represents the regional gold background, and no anomalies are present.

4.4 Kimberlite Indicator Mineral Counts
The glacial sediments in contact with the magnetic kimberlite targets at Holes 17 and 18 on the northern satellite claim block consist of till interdigitated with esker sand/gravel (Fig. 13). Ten samples of these sediments were processed for kimberlite indicator mineral grains (Table 7). No indicator minerals were found.
4.5 Mineralogy and Geochemistry of the Heavy Mineral Fraction of the Till
The regional heavy mineral assemblages of the till/gravel samples from Holes 17 and 18 on the northern satellite claims were recorded (Table 8) while logging the concentrates for kimberlite indicator minerals. The main minerals present are paramagnetic almandine and hornblende and nonparamagnetic diopside and epidote. The unlogged heavy mineral concentrates from the main claim block probably have essentially the same mineralogy because their gold grain content is the same. However, since the latter concentrates were geochemically analyzed and the analytical package included sulphur (Table 9), the pyrite content of the concentrates can be estimated. Most samples yielded ^ percent sulphur but a few yielded 5-30 percent, indicating the presence of 10 to 60 percent pyrite.
To be considered anomalous in gold, a heavy mineral concentrate must yield M 000 ppb Au. Furthermore, the anomaly must be caused by ten or more small, pristine to modified (i.e. little-travelled; Fig. 8) gold grains or by gold hidden in sulphide minerals, not by one or two large, reshaped gold grains. Four Au anomalies MOOO ppb (Table 9) were obtained from the analysed till samples (i.e. samples
collected on the main claim block). These anomalies are in Samples 05 (l 100 ppb) and 07 (l 060 ppb) from Hole 06, Sample 19 from Hole 09 (l 050 ppb) and Sample 02 from Hole 14(1970 ppb). However,
none are genuine anomalies. The strongest anomaly, in Hole 14, had been forecast (Table 6, Appendix C), on the basis of a large gold grain that was observed when the sample was processed. Similar large gold grains were not observed in the other three samples but nevertheless are inferred to have been present because the anomalous samples are bracketed by barren samples (Figs. 11,12) and also yielded low sulphur analyses, indicating that the gold is not hidden in sulphide minerals. Furthermore, the Au is not accompanied by anomalous As, Ag, Cu, Zn or Pb; indeed all analyzed metals occur at low concentrations throughout the till on the main claim block.

Table 8 - Major nonferromagnetic heavy minerals present in the till and gravel samples from the satellite claims. The assemblage almandine-homblende/diopside-epidote indicates that only four major minerals are present, with almandine exceeding hornblende in the paramagnetic (O.8 amp) fraction and diopside exceeding epidote in the nonparamagnetic (M.O amp) fraction. Only the pale green, white and orange varieties of epidote are nonparamagnetic; common pistachio-green epidote reports to the neutral (0.8-1.0 amp) fraction and is not included in the mineral assemblage.

5. CONCLUSIONS AND RECOMMENDATIONS
The reverse circulation drill holes on the main claim block of the West Lake Abitibi Property were targeted on the contact between the Scapa turbidites and Stoughton - Rocquemaure komatiites based on the assumptions that l) this overburden-covered contact is further north than previously thought and thus is virtually unexplored, and 2) the contact represents the western extension of the gold-fertile Lake Abitibi Deformation Zone. The drilling has verified the northerly location of the contact but has also demonstrated that the contact is unsheared, unaltered and unmineralized and therefore is probably a normal, conformable contact. Furthermore, the till overlying the contact contains only background levels of gold grains and its heavy mineral fraction, although locally enriched in pyrite, is not anomalous in gold or any of the usual gold-associated metals. Therefore no further exploration is warranted along or up-ice (north) of the contact. However, the Lake Abitibi Deformation Zone could alternatively follow a formational conductor within the komatiites on the southern edge of the property as originally proposed by Pyke et al. (1972). This regional-scale conductive zone resembles the one associated with the structurally incompetent graphitic mudstones that host the productive Casa Berardi Fault in Quebec (Pattison et al. 1986). The deformation/alteration zone at Casa Berardi is up to l km wide and is flanked by additional, outlying shear zones. Therefore the Lake Abitibi Deformation Zone, if it is indeed present on the West Lake Abitibi Property, should be of a sufficient scale to have been intersected during diamond drilling programs previously conducted in the area. It is recommended that all available diamond drill hole logs be scrutinized for evidence of the deformation zone and associated mineralization before contemplating any further gold exploration on the property.
The two reverse circulation drill holes on the northern satellite claims were targeted on kimberlite- compatible aeromagnetic anomalies. The drilling has shown that the western anomaly is caused by weakly magnetic pyroxenite. Nonmagnetic cherty sediments interleaved with mafic volcanics were intersected at the eastern anomaly but the drill hole was not centered on the anomaly. Therefore the anomaly is unexplained. It could be caused by a magnetite-bearing facies of the chert or mafic volcanics or by a second, smaller pyroxenite intrusion but it is definitely not due to kimberlite as no KIMs were obtained from the till and gravel overlying either magnetic anomaly. Kimberlite pipes normally occur in clusters or "fields" that produce major, regional-scale KIM dispersal plumes in the till. Therefore the total absence of KIMs at the targeted anomalies not only condemns these two anomalies but also all others for many kilometres up-ice. Consequently no kimberlite exploration is warranted on the other, untested satellite claim blocks of the West Lake Abitibi Property.

The only positive result of the reverse circulation drilling is the discovery of disseminated chalcopyrite mineralization in the cherty exhalites of Hole 18. The mineralization is very weak (only 200-300 ppm Cu) but the ratio of chalcopyrite to pyrite is appealing (1:10) and could signal proximity to economically significant volcanogenic massive sulphide mineralization. Although the area is thought to be underlain by monotonous Scapa turbidites, the overburden cover is so thick that the geology is essentially unknown. Felsic volcanics could be present and short, weak airborne electromagnetic anomalies occur several hundred metres to the north and south (Fig. 5). If found to be undrilled, these anomalies should be ground checked as potential volcanogenic massive sulphide targets.
