March 2008 Quarterly Report
Highlights
Maitland Copper Deposit
-
Resource definition drilling completed at the Maitland Copper Deposit. Results confirm the continuity of high grade copper and molybdenum mineralisation which remains open at depth.
-
New Indicated Mineral Resource estimated of approximately 1.5 Mt @ 1.48% copper (0.5% cut off) , which includes a continuous high grade core containing 75,000 tonnes @ 4.8% copper (3% cut off). Good potential to increase the resource with deeper drilling.
-
Indicated high grade molybdenum resource of 115,000 tonnes @ 0.17% molybdenum estimated within the copper resource. The molybdenum zone appears to be improving with depth.
-
Preliminary metallurgical test work indicates excellent copper recoveries (>95%) in the primary zone and up to 75% in the oxide zone. The primary zone accounts for 87% of the resource.
-
Open pit optimisation studies indicate good potential for a profitable mining operation based on trucking ore to a third party mill. Studies indicate robust project economics at copper prices as low as A$4,000 per tonne (currently ~$A9,500 per tonne).
Priorities for the June 2008 Quarter
-
Continue the review of options for optimising value from the Maitland Copper Deposit including continuing discussions with other parties regarding development alternatives.
-
Commence follow up of new gold, base metal and uranium targets on recently granted tenure at the Percyvale and Hampstead Projects in North Queensland.
-
Secure drill rig to test Acacia North gold target at the Rum Jungle Project in the Northern Territory.
-
Finalise access agreement with Traditional Owners for the Citadel Project in northwest Western Australia.

Glengarry Resources Limited – March 2008 Quarterly Report
Project Activities Report
NORTH QUEENSLAND
The shoot remains open at depth with strong copper mineralisation observed down to 300 metres below the surface.
Greenvale Project – New resource estimated for Maitland copper deposit. Optimisation studies indicate positive economics.
Validation and processing of results from resource definition drilling completed late last year at the Maitland copper deposit was the main activity carried out for the Greenvale Project (Figure 1) during the Quarter. Independent consultants were engaged to estimate an updated, JORC compliant resource which was then used as the basis for open pit optimisation studies. Results are very encouraging and indicate good potential for an economically viable mining operation at Maitland.
Maitland Deposit – Drilling Results
Final assay results for the 68 hole/8,520 metre resource definition drilling program completed in December 2007 were received during the Quarter.
The results confirm the continuity of high grade copper mineralisation in the main southern shoot (Figures 2 & 3) which contains the bulk (~75%) of the resource.

Maitland Deposit – Resource Estimation
Resource consultant, Cube Consulting Pty Ltd was engaged to estimate an updated resource for the Maitland copper deposit.
A summary of the Mineral Resources estimate for the Maitland deposit is tabled below based on cut off grades of 0.5% copper and 0.04% molybdenum. Approximately 98% of the Mineral Resource is classified as indicated.
The resource estimation methodology and tables showing mineral resources using
different cut off grades are provided in Appendix 2.
The Mineral Resource for the southern shoot is classified as Indicated above the 350m RL (approximately 210 metres vertical depth) and as Inferred below. A continuous, high grade core containing 75,000 tonnes at 4.8% copper (Figure 5) has been defined down to the 400m RL (approximately 160 metres vertical depth) with further drilling required to confirm continuity below this level. There is good potential to increase the resource for the southern shoot with deeper drilling.

Glengarry Resources Limited – March 2008 Quarterly Report
The Mineral Resource for the northern shoot has been estimated down to the 500m RL (approximately 80 metres vertical depth) and is classified as Indicated.
Encouraging gold intercepts were returned from the Steam Engine prospect during the Joint Venture’s 2007 drilling program including:
- 6 metres @ 5.5 g/t gold from 95 metres
Maitland Deposit – Optimisation Studies
Engineering consultant, Lower Quartile Solutions Pty Ltd (LQS) was engaged to run provisional open pit optimisations using Whittle software on the Indicated portion of the Maitland Mineral Resource. The optimisations were run using a range of copper prices ranging from A$3,500 per tonne to A$10,000 per tonne. Cost parameters were provided by Glengarry and analysed by LQS to ensure they were robust estimates.
The optimisation results indicate positive cash flows are possible from copper prices as low as A$4,000 per tonne. The Scoping Study assumes that ore will be transported to a mill up to 350 kilometres away and that limited infrastructure would be required on site.
-
12 metres @ 2.5 g/t gold from 10 metres
-
5 metres @ 4.5 g/t gold from 19 metres
-
5 metres @ 4.3 g/t gold from 24 metres.
Beacon is managing exploration on the tenements and is planning additional drill testing at a number of prospects in mid 2008. Further details are provided in Beacon’s quarterly report.
Copper Creek Prospect
The Copper Creek area is located approximately 44 kilometres south of the Maitland deposit (Figure 1) in the same geological sequence.
Prospecting by Glengarry has recorded up to 3.3% copper, 0.32 g/t gold and 19 g/t silver in rock chip samples and reconnaissance soil sampling has defined anomalous (>200 ppm) copper values over 1.2 kilometres strike. Detailed mapping and prospecting will be completed next quarter to determine whether drill testing is warranted.
Lucky Creek Joint Venture
The north eastern Lucky Creek Group tenements at Greenvale (Figure 1) are subject to a Joint Venture Agreement with Beacon Minerals Limited (Beacon). The tenements cover 195 square kilometres and comprise 10% of the Company’s existing tenure in the Greenvale area.

Glengarry Resources Limited – March 2008 Quarterly Report
Percyvale Project – Grant of tenement application pending. Fieldwork to commence next quarter.
The Percyvale Project is located approximately 50 kilometres due west of the Maitland copper deposit (Figure 1) and was applied for in February 2007. The tenement is expected to be granted in time for initial exploration work to commence in May.
The first tenement application at Hampstead is expected to be granted early next quarter with initial field work scheduled for early May 2008. Glengarry’s priorities will include verification of previous exploration results followed by geochemical surveys and geological mapping to define drill targets as quickly as possible.
WESTERN QUEENSLAND
The Project area is underlain by lithologies belonging to the Proterozoic Einasleigh Metamorphic suite, the same geological sequence that hosts Glengarry’s Maitland copper deposit and Copper Strike’s Chloe base metal deposit (Figure 1).
Previous exploration by other companies has identified a number of gold, base metal and uranium prospects where further work appears warranted.
Glengarry’s initial field work will include verification of previous exploration results followed by geochemical surveys and geological mapping to define drill targets as quickly as possible.
Hampstead Project – New project area prospective for gold, uranium and base metals.
The Hampstead Project is located approximately 30 kilometres south southwest of the Greenvale Project and consists of a number of contiguous EPM applications covering approximately 900 square kilometres. The geological setting of the Hampstead Project is considered highly prospective as it is identical to other parts of the Georgetown Inlier that host significant mineral deposits including Maitland (copper), Chloe (lead-zinc-silver), Kidston (gold) and Maureen (uraniummolybdenum).
Snake Creek Project – Technical review completed.
The Snake Creek Project is located in northwest Queensland approximately 125 kilometres east-southeast of Mt Isa (Figure 6) and on the northern extension of the regionally significant Cloncurry Fault. It is prospective for copper-gold and uranium mineralisation.
Previous soil sampling by Glengarry has defined extensive copper-gold anomalism coincident with the Consternation Trend, a structure interpreted to delineate the western margin of the Cloncurry Fault Zone.
Glengarry is seeking to joint venture Snake Creek. A number of companies have expressed interest and are currently reviewing the technical data for the Project.
Cannington Project – Property relinquished.
Attempts to joint venture the Cannington Project (Figure 6) were unsuccessul. Consequently, Glengarry has elected to relinquish the property.
Exploration work in the 1980s delineated extensive uranium and gold mineralisation in several areas which appear to warrant further exploration. Rock chip sampling recorded multiple uranium anomalies (up to 1.38% U3O8) while limited drilling on gold targets intersected extensive geological alteration and wide zones of mineralisation (up to 53 metres @ 0.5 g/t).

NORTHERN TERRITORY
Rum Jungle Project – Acacia North gold target ready for drilling.
Glengarry’s wholly owned Rum Jungle Project covers approximately 140 square kilometres in the Rum Jungle area located 65km south of Darwin in the Northern Territory. The Project is proximal to the historical Rum Jungle uranium mine (3,530 tonnes U3O8) and the Woodcutters lead-zinc mine (~6 Mt @ 12% zinc and 6% lead).
Quarter. Most matters have been resolved and it is hoped to complete the agreement during the coming quarter.
Glengarry’s has already planned a drilling program comprising approximately 10,000 metres of aircore drilling to test a 8 - 10 geochemical and geophysical targets defined by previous explorers. This work will be commence as soon as the southern ELs are granted and a suitable drill rig contracted.
Previous explorers intersected high grade gold mineralisation at Acacia North (up to 6 metres @ 11.3 g/t gold) which is open in all directions. Glengarry has designed a 1,000 metre reverse circulation percussion drill program to test for extensions of the gold mineralisation.
Unfortunately, the Company’s attempts to carry out the proposed drilling program have been unsuccessful due a shortage of suitable drill rigs in the Northern Territory. All preparatory work has been completed to enable drilling to occur as soon as an appropriate rig becomes available.
WESTERN AUSTRALIA
Citadel Project (Northwest Western Australia) – Access negotiations continuing.
The wholly owned Citadel Project covers approximately 1,700 square kilometres in the Paterson geological province and is located 100 kilometres north of the Telfer gold mine. The region contains several world class uranium, gold and copper deposits including Kintyre (36 Kt tonnes U3O8), Telfer (26 M oz gold, 1 Mt copper) and Nifty (1 Mt copper).
The Project comprises 4 Exploration Licences (ELs). An access agreement has been reached with the Native Title claimants for the northern ELs and a meeting held to discuss details of a heritage survey over the proposed work area.
Access negotiations with the Martu people, the Traditional Owners (TOs) of the southern ELs continued during the

Glengarry Resources Limited – March 2008 Quarterly Report
Appendix 2: Resource Estimation Methodology
Glengarry Resources Limited undertook the initial interpretation work and this was modified as necessary in consultation with Cube Consulting Pty Ltd (“Cube”) prior to resource estimation. Cube believes that the current geological model is fundamentally sound and provides an appropriate basis for the Scoping Study.
Cube adopted a traditional 3D block modelling approach for the resource estimate. All samples within a mineralised zone were assigned a unique database code. Sample grades were composited to 2.5m down hole using the unique coded interval as a control.
Statistical analysis was carried out to check stationarity and to determine the need for high grade assay cuts. A top cut of 10% copper was applied to remove statistical outliers.
Variography has been used to analyse the spatial continuity of each element and to determine appropriate estimation inputs to the interpolation process for the main mineralised domains and within the metallurgical horizons. Grade interpolation was carried out using Ordinary Kriging (OK) into Y=20m X=10m Z=2.5m parent cells.
Bulk density values were assigned after analysis of the measured bulk density data for Maitland. The assigned bulk densities were 2.20 g/cm[3] for all oxide rock, 2.65 g/cm[3] for fresh waste rock and 2.80 g/cm[3] for fresh mineralised material.
Resource estimates using different copper cut off grades are tabled below:
