SummaryProject Aim

EPM 14624 (Sherrin) is one of 17 exploration permits applied for to explore for channel and drainage related, or fossil palaeochannel, roll front gravel, sandstone and calcrete hosted near surface uranium deposits within the Cambrian Georgina Basin in northwest Queensland.

The area is also potentially prospective for uranium and base metals in the underlying Proterozoic basement.

Location

EPM 14624 is centred 115km west of Mount Isa and covers an area of 803km2 on the Mount Isa (SF54-1) 1:250,000 Sheet at the junction of the Yelvertoft (6657) and Templeton (6656) 1:100,000 Sheets.

Tenure

EPM 14624, consisting of 100 sub-blocks, was granted to Summit Resources (Aust.) Pty Ltd on 28 February 2005 for a period of 5 years ending on 27 February 2010. In April 2008 Summit relinquished 50 sub-blocks, representing 50% of the tenement area from EPM 14624.

Transfer of the tenement to Newland Resources Ltd was registered in October 2008

Exploration

Exploration activity included compilation and interpretation of previous exploration data, acquisition of imagery and geophysical data from Geoimage Pty Ltd and detailed basin analysis by Fullagar Geophysics and FrOG Tech Pty Ltd. A detailed airborne electromagnetic survey was flown to examine potential for palaeochannel development in the region.

Conclusions

Uranium rich material eroded from the Mount Isa Inlier is transported into the Georgina Basin by current drainages within EPM 14624. Uranium targets on the tenement are weak and historical exploration data and the results of the airborne EM survey commissioned by Summit did not identify any priority drilling targets in the tenement.

Recommendations

Further uranium exploration is not recommended at this stage.

Introduction

EPM 14624 is one of 17 granted exploration permits that comprise the Georgina Basin Project. The Project was initially explored under the terms of the Georgina Basin Joint Venture between Summit Resources (Aust.) Pty Ltd (“Summit”) and Newland Resources Limited (“Newland”). Under the terms of the Joint Venture Agreement Newland had the right to acquire a 50% interest in the Project through sole funding of exploration expenditure.

Following Board and management changes in Summit’s parent company, Summit Resources Limited, in mid 2007 Summit’s exploration activity in the Mount Isa Region became focused on uranium and base metal targets in the Mount Isa Inlier to the east of the Georgina Basin. Summit determined to divest its interest in the Georgina Basin and Newland agreed to acquire a 100% interest in the 17 exploration permits that comprise the Georgina Basin Project.

The Georgina Basin Project tenements extend from approximately 50 kilometres west to 180 kilometres to the southwest of Mount Isa and cover an area of 11,625km2.

The Georgina tenements are sub-divided into three geographical locations and named on the basis of the main drainage system in the area. The sub-projects from north to south are: -

TEMPLETON – EPMs 14624, 15746, 15750, 15751 15753 15757 15758 and 15759 (5,448km2);

MOONAH – EPMs 15744, 15745, 15747, 15749, 15752 and 15755 (4,366km2); and GEORGINA – EPMs 15748, 15754 and 15756 (1.776km2).

The tenements are located over the eastern margin of the Cambrian aged Georgina Basin adjacent to and immediately west of the Mount Isa Inlier where world class base metal mines and major uranium deposits have been delineated in Proterozoic basement

The primary exploration targets on EPM 14624 are: -

channel and drainage related uranium mineralisation and palaeochannel, roll front gravel, sandstone uranium deposits within the Cambrian basin sediments;

calcrete hosted near surface uranium deposits; and

deep-seated copper, uranium, gold, lead and zinc deposits associated with major regional structural faults in the Proterozoic basement.

Exploration programs conducted during the term of the permit included: -

Compilation of previous work in an integrated GIS environment. Reprocessing of past airborne and ground EM data to identify cover and basement

conductivities. Acquisition of magnetic and radiometric airborne surveys. Acquisition and review of all water bore and petroleum information in the area. Acquisition of thermal and satellite imagery for entire area. Develop digital terrane model. Development of detailed basin model and interpretation of basement geology. Fly airborne EM survey over tenement as part of survey of the entire west Isa region –

completed over the Templeton area including all of EPM 14624.

Access to EPM 14624 is gained via the Barkly Highway north from Mount Isa towards Camooweal for a distance of approximately 58 kilometres to the Old May Downs Road turn- off to the west. The May Downs Road provides access to the tenement via various station tracks on May Downs Station along the Mingera Creek to Brumby Dam approximately 40 kilometres from the Highway.

Project and tenement location plans are shown in Figure 1.

EPM 14624, consisting of 100 sub-blocks, was granted to Summit Resources (Aust.) Pty Ltd on 28 February 2005 for a period of 5 years ending on 27 February 2010. In April 2008 Summit relinquished 50 sub-blocks, representing 50% of the tenement area from EPM 14624.

Transfer of the tenement to Newland Resources Ltd was registered in October 2008 and the remaining 50 sub-blocks were relinquished by Newland on the licence anniversary in February 2009.

Regional Geology

EPM 14624 is located near the eastern margin of the Georgina Basin which is a large intracratonic basin rimmed by Mid-Proterozoic rocks of the Mount Isa Inlier to the northeast and the McArthur River and South Nicholson basins to the north.

The Mount Isa Inlier is subdivided into three north trending provinces – the Western Fold Belt Province, the Kalkadoon-Ewan Province and the Eastern Fold Belt Province. The Western Fold Belt Province is further divided into the western Lawn Hill Subprovince and the Leichardt River Subprovince in the east separated by the Mount Gordon Fault Zone.

The Georgina Basin Project area tenements cover Georgina Basin sediments overlying Proterozoic basement of the Lawn Hill Platform. The Lawn Hill basement evolved from deformation and metamorphism of sedimentary, volcanic and intrusive rocks during the Barramundi Orogeny at about 1870Ma followed by deposition of volcano-sedimentary cover sequences during extensional tectonism up to the Isan Orogeny at 1620 to 1520Ma. Sedimentary rocks of the dominate cover sequence in the Western Fold Belt Province were laid down in shallow marine and fluvial environments with subaerial volvanics indicating the presence of pre-existing continental basement.

Granite and mafic intrusive were emplaced at various times up to 1100Ma and in the Western Fold Belt the main batholith is the Sybella Granite which is dated at about 1670Ma.

The Mount Isa Orogeny has had a complex tectonic history dominated by different periods of extension, shortening and transcurrent faulting. The earliest basement deformation was the shortening attributed to the Barramundi Orogeny which produced tight folding and partial melting followed by extension leading to basin development and deposition of the cover sequence in an extensional basin the Western Fold Belt. A phase of thrusting and folding resulting from north-south compression at about 1620Ma was followed by east-west compression of the Isan Orogeny at 1520Ma which formed major north trending upright folds which characterise the Mount Isa Orogeny.

The fine grained sedimentary cover rocks in the Western Fold Belt host major silver, lead and zinc deposits including Mount Isa Pb-Zn, Century, Hilton, George Fisher and Lady Loretta. Brecciated sediment-hosted copper deposits at Mount Isa and Esperanza/Mammoth occur in brecciated dolomitic, pyritic and carbonaceous sedimentary rocks or brecciated sandstones proximal to regional shears in the Western Fold Belt Province.

The present-day distribution of basement terranes in the project area has been interpreted by FrOG Tech from the magnetic and gravity data-sets, calibrated with outcrop data. Three basement terranes can be identified:

Mount Isa Terrane, Arunta-Altjawarra Terrane

and Tennant Creek Terrane.

These terranes are part of the North Australian Craton (NAC). The final formation of the NAC might have been achieved during the Barramundi Orogeny (e.g. Betts et al., 2006).

Arunta-Altjawarra Terrane: This complex terrane is interpreted to be relatively “weak” and as a result has been deformed considerably throughout its history (e.g. Strangways event, Chewings event). This softness could be a result of high-heat producing granites (e.g. Teasdale and Pryer, 2002). The Alice Springs Orogeny was the last event that extensively reworked the terrane and produced its present configuration. The eastern part of the terrane corresponds to the Altjawarra, which was less affected by the Alice Springs Orogeny than the western part

(i.e. the Arunta Terrane).

The terrane consists of:

• Pre-Barramundi widespread clastic sediments, which are intruded by numerous mafic-ultramafic bodies (e.g. Claoué-Long and Hoatson, 2005), and deformed under amphibolite- to granulite-facies conditions during the (~1.78 – 1.71 Ga) Strangways Orogeny (Maidment et al., 2005).



Page 10 of

• Post-Barramundi basement, which includes Paleoproterozoic sequences from the Leichardt, Calvert and Isa Superbasins. These sequences were metamorphosed during the Isan Orogeny and include marine and fluvial successions, as well as mafic volcanic layers.

Mount Isa Terrane: The pre-Barramundi basement of the Mt Isa Terrane is poorly understood. It includes Palaeoproterozoic supracrustal successions deformed and metamorphosed to amphibolite facies during the Barramundi Orogeny (e.g. Etheridge et al., 1987), as well as tonalitic, granodioritic and granitic rocks (e.g. Kalkadoon and Ewen Batholiths). Basement is generally migmatitic to gneissic, although greenschist facies schist and phyllite are also preserved. Exposures of pre-Barramundi basement are generally restricted to the Kalkadoon–Leichhardt Belt and the southern areas of the Western Fold Belt (Betts et al., 2006).

Post-Barramundi basement includes batholiths and Paleoproterozoic sequences from the Leichardt, Calvert and Isa Superbasins. These sequences were metamorphosed during the Isan Orogeny and include marine and fluvial successions, as well as mafic volcanic layers.

Tennant Creek Terrane: The Tenant Creek Terrane comprises tightly folded Paleoproterozoic clastic metasedimentary rocks (metaturbidites) that have recrystallised under lower greenschist facies conditions. These metaturbidites belong to the (1862-1859) Warramunga Group and are unconformably overlain by the Flynn Subgroup which is composed of a thick sequence of Paleoproterozoic felsic volcanics, volcaniclastic and clastic sedimentary rocks. The entire sequence, has been intruded both by syn- and post-tectonic granitoids and felsic porphyries. Radiometric ages for emplacement of these intrusives range from 1870 to 1650 Ma (Stolz and Morrison, 1994).

Post-Barramundi basement includes Paleoproterozoic sequences from the Leichardt, Calvert and Isa Superbasins. These sequences were metamorphosed during the Isan Orogeny and include marine and fluvial successions, as well as mafic volcanic layers.

Prior to the formation of the Georgina Basin, from ~1800Ma, the project area has undergone a complex tectonic history, which resulted in the formation of the basement fault architecture (often extensional). These faults were reactivated during later phases (within the Paleoproterozoic to Paleozoic), and have formed important conduits during mineralization events (e.g. Betts et al., 2003). Paleoproterozoic sediments were deposited during several phases of basin formation and intruded during different magmatic events. The Isan Orogeny was an important shortening event during which the Paleoproterozoic sediments beneath the Georgina Basin were metamorphosed (low-pressure upper greenschist to amphibolite facies). During a following extensional event, deposits of the South Nicholson were deposited in the South Nicholson Basin, which partly underlies the Neoproterozoic to Paleozoic Georgina Basin.

In addition to the major terranes, FrOG Tech have distinguished the intrusive bodies (granitic or mafic) and extrusives within the basement. The result is a 2D solid geology map produced by calibration for basement composition from geological maps, wells and information from the he North-West Queensland Mineral Province Report (QGDME, 2000).

Post-Barramundi Granite: Undifferentiated felsic intrusions.

Sybella Granite (1660-1650Ma): Part of the McArthur Group. Granite intrusions that intrude the Haslingden Group. Intrusion occurred at the onset of the formation of the Paleoproterozoic Isa Superbasin.

McNamara Group (1653-1595Ma): Is considered part of the Gun Supersequence, includes Pilpah Sandstone which autcrop in the northern part of the project area. The McNamara Group comprises carbonaceous shale, stromatolitic dolostone, turbiditic sandstone and siltstone

• Gunpowder Creek Formation (1665-1590Ma): Forms part of the McNamara Group. The dominant lithology is a laminated red and green micaceous siltstone and fine grained micaceous sandstone. Dolomite, dolomitic siltstone and leached carbonaceous shale are common toward the top of the sequence.

Surprise Creek Formation (<1700Ma): Basal conglomerate with clasts of quartz, quartzite and rhyolite in a matrix of medium to coarse grained sublithic sandstone; thick bedded, medium to coarse grained, sublithic to quartz sandstone.

Haslingden Group (1800-1710Ma): Sediments of the Haslingden Group were deposited in a relatiavely stable shallow water environment, which persisted despite repeated extrusion of basalt, but was terminated by tectonism accompanying Sybella Granite intrusion

• Myally Subgroup: Part of the Haslingden Group. Generally a sandstone series consisting of either mature, silica-cemented white quartzite or immature, orange weathering ferruginous sandstone.

• Eastern Creek Volcanics (1735-1685Ma): Part of the Haslingden Group. The Eastern Creek Volcanics correspond to highly magnetic mafic extrusives, intercalated with metasediments.

• Mount Guide Quartzite: Part of the the Haslingden Group. Quartzite, feldspathic and micaceous quartzite, minor gneiss. Includes the May Downs Gneiss member.

• Leander Quartzite (1800-1757Ma): Part of the Haslingden Group. Consists of Orthoquartzite, feldspathic quartzite; schist, arkose and metabasalt

Throughout the project area the Proterozoic basement is concealed by the often thick (>500m) Georgina Basin sediments. The development of the Georgina Basin was linked to the formation and subsequent deformation of the Centralian Superbasin, a huge intracratonic sedimentary basin covering 2.5 million km2 in Central Australia formed in the Neoproterozoic era.

Disruption of the Centralian Superbasin commenced with the Petermann Orogeny, an intraplate orogeny related to the collision and accretion of the East and West Gondwana plates. This and nine later deformational events resulted in fragmentation of the Superbasin and formation of the Georgina, Amadeus, Officer and Ngalia basins.

The origin and formation of Georgina Basin and potential synergies with the Amadeus, Officer and Ngalia basins, which contain known uranium mineralisation, are important factors in the conceptual exploration model for this project.



Page 12 of

The Georgina Basin consists of predominately marine carbonates and lesser sandstones, siltstones, cherts and phosphorates of Cambrian age overlying the Middle Proterozoic basement rocks of the Lawn Hill Platform of the Western Fold Belt. The Cambrian contact with the basement Proterozoic is a major unconformity and has been observed in drill core elsewhere in the area to be anomalous in copper and iron.

Outcrop is generally poor in the project area as Recent cover (black soils, sands and ferruginous gravels) up to a maximum of 20m thick obscures the underlying Cambrian Platform sequence dominated by dolomites and limestones.



Page 13 of

Tenement GeologyThe Georgina Basin sediments are relatively shallow in EPM 14624 with feldspathic sandstones of the Pilpah Sandstone mapped in the northern and central portions of the tenement. These outcrops are mapped as Tertiary duricrust on the Mount Isa 250,000 Sheet and confirmation of the geology is required.

The Pilpah Sandstone represents Proterozoic basement in the area and public domain gravity data was utilised to develop a basin model and contour sediment thickness. The model indicates that Cambrian sediments are only about 200m thick tenement area but thickening to the southwest corner of the licence.

Cambrian Camooweal Dolomites outcrop intermittently throughout the area and Quaternary alluvium, sand and lucastrine deposits and Late Cainozoic residual sand and gravels cover much of the region.

Delivered products:Located data (ASCII files in Fugro & AMIRA formats)Gridded data (TMI, TMI1vd, DTM, 30xEM amplitudes, time constants, depth to resistive basement)Various maps and a processing & acquisition report

A copy of the Acquisition and Processing Report provided by the survey contractor, Fugro Airborne Surveys, was submitted to the Geological Survey of Queensland in July 2007. The located digital data were submitted to the Geological Survey of Queensland in February 2008. The format of the data provided is such that it is not possible to extract and compile located data for individual sub-blocks.

These datasets were used to compile a preliminary interpretation of the area and incorporated in specific basin studies conducted by Fullagar Geophysics and FrOG Tech Pty Ltd.

Fullagar conducted full 3D inversion of the gravity data, constrained by surface topography, Proterozoic outcrop and limited available drilling to produce a simple two layer model of the project area comprising undifferentiated sediments overlying Proterozoic basement employing 2 x 2km model cells in plan. This model provided an interpretation of basement depth and density to assist with exploration planning and targeting.

FrOG Tech Pty Ltd undertook a structural evaluation of the east Georgina Basin further refining the basin modelling to generate regional basement and basinal structural maps, interpret the structural history of the basin, develop a tectonic model of the basin to aid identification of basement highs and define potential palaeochannel locations along the eastern edge of the basin.

No sampling or drilling was undertaken by on EPM 14624 and there is no surface sampling or drilling data to report.

Discussion and ConclusionAnalysis of radiometric data using the uranium-channel has outlined near surface areas which are potentially rich in uranium (Figure 8). Four types of areas have been identified:

Near-surface or outcropping Mount Isa basement, which is rich in uraniferous material (blue areas on the Ternary Radiometric Map). These zones are to the east of the Newland tenement block but represent strongly mineralised source material for erosion, transportation and deposition of uranium in current and palaeo-drainage systems within the Georgina Basin.

Rivers transporting uranium rich clastics from the Mount Isa Inlier into the Georgina Basin correspond to linear anomalies on the radiometric images with radiometric values within the channels highest near the Mount Isa Inlier, and gradually fade out into the basin.

Between present-day river channels, some locations show weak anomalies, similar to those of the active river channels. These have been interpreted to be abandoned or palaoe-river channels.

Strong uranium anomalies in the western half of the project are entirely caused by uranium, and have been interpreted to be local zones of uranium enrichment correspond to surficial duricrusted sediment uranium deposits primarily located within outcropping Middle Miocene Austral Downs Limestone. These include limestone and chalcedony which formed in brackish lacustrine and spring environments. They overlie limestone and ferruginous detritus, and could provide the reducing environment, needed to precipitate uranium. The setting of this enrichment zones could be similar to that of the Yeelirrie uranium deposit in Western Australia.

Page 23 of

Radiometric images demonstrate the transportation of uranium rich material eroded from the Mount Isa Inlier into the Georgina Basin by current drainages within EPM 14624.

A detailed airborne electromagnetic survey was flown in 2007 to examine potential for palaeochannel development in the region. Figures 7 and 8 illustrate conductivity at various depths in the area and the electromagnetic interpretation by Fugro and FrOG Tech does not highlight potential for palaeochannel targets within EPM 14624.

Figure 7: Shallow Airborne Electromagnetic Image – showing conductivity at surface to 30m depth.



Page 24 of

Figure 8: Deep Airborne Electromagnetic Image – showing conductivity at >40m depth.

The 1,000-metre flight line spacing of the airborne EM survey, coupled with the lack of outcrop and extensive Tertiary cover in EPM 14624 have limited the usefulness of the EM survey as a tool able to identify specific targets for detailed surface investigation and drilling. A more detailed close-spaced airborne EM survey coupled with other airborne geophysical techniques remains as a potential exploration method that could be applied in the area of EPM 14624 and its surrounds.

Uranium targets on the tenement are weak. Radiometric data indicates some transport of weathered uraniferous material into the area by current drainage systems however the drainages are broad and diffuse and concentration of uranium in the channels is not evident.

Historical exploration data available for the ground in and surrounding EPM 14624 including drill hole records and the results of the airborne EM survey commissioned by Summit did not identify any drilling targets in the tenement.

Further exploration is not recommended at this time. Examination and interpretation of the significant amount of historical exploration data available for the ground in and surrounding EPM 14624 including drill hole records and the results of the airborne EM survey commissioned by Summit did not identify any priority drilling targets in EPM 14624.



Page 25 of

The extensive areas of tertiary cover and lack of outcrop suggest that surface exploration techniques (geophysics, soil geochemistry) are unlikely to yield useful data and drilling in the search for mineralisation is not justified in the absence of specific targets.

Newland is relinquishing the tenement to concentrate exploration efforts on higher priority targets elsewhere in the Georgina Basin Project.
