Gwalia, Leonora, WA

The Gwalia mine produced 43,881 ounces of gold at a mined grade of 9.3 g/t Au and cash operating cost of $627 per ounce (Dec 11 qtr: 46,007 ounces; 8.1 g/t Au; $683 per ounce). Mine production rates and mined grades were in line with expectations.

The majority of the ore mined for the quarter was sourced between 1,280 metres below surface (mbs) and 1,340 mbs from the higher grade South West Branch. South West Branch is expected to be the principal ore source for the foreseeable future.

Significantly lower cash operating costs of $627 per ounce (Dec qtr: $683 per ounce) were primarily due to the higher mined grade.

During the March quarter, mining activity included developing the 1380 level, to provide access to the next sequence of production stopes. As a consequence, stope ore mined was lower for the March quarter.

Scheduled mill maintenance in January resulted in a lower volume of Gwalia ore milled. Since this time, the mill has continued to operate at, or above, design capacity.

Processed tonnes for Gwalia included some mineralised waste and low grade stockpiles from Tower Hill during the quarter, resulting in a milled grade of 8.4 g/t Au.

Recoveries of 97% continued to exceed expectations with approximately 50% of the gold in ore reporting to the gravity circuit.

Outlook

Production for the June quarter is expected to increase by at least 10% over the March quarter, driven by a return to the forecast 700,000 to 730,000 tonne annualised ore production rate. This will lead to full year gold production within the guidance range of 175,000 to 190,000 ounces.

Mined grade is anticipated to be lower for the June quarter due to slippage in accessing a high grade stope. The average mined grade for the June quarter and for the year is still expected to be within the guidance range of 8.0 to 8.5 g/t Au. Cash operating costs per ounce for the June quarter are expected to be similar to the March quarter. Lower grade will be offset by higher volume to deliver annual gold production to guidance. Overall, cash operating costs per ounce for FY12 are expected to be in the range of $650 to $660 per ounce.

The Definitive Feasibility Study for a hoisting shaft in the Gwalia mine is progressing to plan. The objective of the study is to assess the viability of installing a shaft to efficiently haul ore and waste in substitution for truck haulage, thereby significantly lowering haulage costs per tonne and enabling a higher proportion of mineral resources to be converted to ore reserves.

King of the Hills, Leonora, WA

A 27% increase in ore mined from King of the Hills for the quarter was the primary contributor to a 21% increase in gold production and significantly lower cash operating costs of $693 per ounce (Dec 11 qtr: $754 per ounce).

1 Includes Tower Hill low grade stockpile and Gwalia mineralised waste.

Southern Cross Operations, WA

Gold production for Southern Cross Operations increased by 6% for the quarter, due to an increase in the volume of Marvel Loch underground ore. The volume of ore mined, grade, recovery and production were all in line with expectations.

In addition to ore from Marvel Loch, approximately 290,000 tonnes of low grade stockpiles from historic mining sites on the Company's tenements were processed. Unit cash operating costs for the March quarter were higher primarily due to the lower grade from Marvel Loch.

Net cash generation from Southern Cross Operations continues to exceed the margin indicated by the operating costs per ounce set out above, as most of the level development costs have already been paid for.

Southern Cross Operations received a Gold Certificate from the Western Australian Water Corporation in April for the implementation of water efficiency measures that have resulted in significant water savings.

Outlook

Underground mining operations from Marvel Loch are expected to continue through to at least October 2012. Supplemented by low grade stockpiles, processing is expected to continue until at least December 2012. Southern Cross Operations is expected to meet its production guidance for FY12.

Discovery and Growth

Leonora Region, WA

Gwalia mine – testing for extensions to north and south**:**

The Gwalia Mine 'Phase Three' deep drilling program comprising 7 drill holes has been completed ahead of schedule and under budget. The program has successfully extended the Gwalia lodes along the northern and southern margins, with the aim of increasing Mineral Resources and converting a substantial portion of existing Inferred Resources to Indicated Resources and potentially to Ore Reserves, within the current planned mining interval.

Significant results included the following (all intercepts down-hole, details in Table 1 and shown on Figures 1 & 2):

• GWDD11J: 8.4m @ 6.6 g/t Au from 1,638m, South West Branch (SWB), and 2.3m @ 8.3 g/t Au from 1,668m (including 0.3m @ 52.0 g/t Au), South Gwalia Series (SGS);
• GWDD11K: 3.7m @ 8.8 g/t Au from 1,669m (SWB);
• GWDD11L: 6.6m @ 41.1 g/t Au from 1,679m (SWB);
• GWDD11M: 5.9m @ 9.3 g/t Au from 1,648m (SWB), and 4.0m @ 48.9 g/t Au from 1,659m (SWB);
• GWDD12K: 2.3m @ 18.8 g/t Au from 1,856m (SWB);
• GWDD12L: 5.0m @ 3.6 g/t Au from 1,830m (SWB).

The Gwalia deposit remains open along both margins to the north and south and at depth, albeit thinning to the north. These results are being compiled in preparation for a revised resource estimate.

Leonora targets: Drilling has commenced on high priority targets, undercover on the Gwalia mine trend, with the objective of discovering Gwalia style deposits. It is expected that a total of 10 to 12 further deep holes will be drilled in the June quarter.

Southern Cross Region, WA

Drill testing was completed on five projects:

Nevoria: A 10 hole drilling program has been completed at Nevoria located 5km SE of the Marvel Loch mine, confirming the existing geological interpretation and upgrading resource categories at Nevoria project. A resource estimate has been completed, which has not materially changed grade or tonnages. This will form the basis of a feasibility study for a potential underground mining operation to contribute material to the Marvel Loch plant.

Frasers: The final two drill holes of this second phase, eight hole drill program were completed. The program has further extended the high grade mineralisation hosted by banded iron formation (BIF) rock units in the main shear zone, following the southerly plunge of lodes at depth.

Significant intercepts during the quarter included the following (all intercepts down-hole, details in Table 1):

• FSDD0021: 3.3m @ 12.5 g/t Au from 332m;
  • FSDD0017: 4.8m @ 12.6 g/t Au from 278m (re-assay result).

These intersections have confirmed the variable grade and thickness of the BIF, as well as the pinching and swelling within the main Frasers shear zone down-plunge.

Results from this drilling program are being compiled for an initial resource estimate and as a potential source of material for the Marvel Loch processing plant.

To test the potential of this BIF-hosted mineralisation extending further south, a series of 13 holes were drilled on the Cornishman project, located 5km SE of Frasers on the same regional shear zone (Figure 6). Significant intersections included:

• CMRD1004: 7.0m @ 6.6 g/t Au from 341m;
• CMRC1007: 5.0m @ 2.1 g/t Au from 115m;
• CMRC1008: 2.0m @ 5.7 g/t Au from 140m.

Follow up drilling is being considered below the high grade intersections above.

Near the Corinthia project, located 15km NW of Frasers, three drill holes were completed on the main regional shear zone without intersecting significant gold mineralisation.

Copperhead: The Phase 2 drilling program of four holes has been completed with significant intersections of up to 30m in the Western Series Lode, but with generally low to medium grade. Higher grade intersections came mainly from the Southern Series Lode at depth, and included:

• CHDD010: 2.8m @ 3.5 g/t Au from 491m;
• CHDD010A: 14.0m @ 1.2 g/t Au from 488m and 6.4m @ 22.2 g/t Au from 615;
• CHDD011: 5.7m @ 3.0 g/t Au from 772m;
• CHDD012: 6.6m @ 5.9 g/t Au from 881m.

Other Areas

Yilgarn province, WA: Geochemical air-core drilling is planned on a number of prospects in the Yilgarn province to generate new drill targets. Elsewhere, regional targeting studies are continuing to generate priority areas with potential for larger higher grade deposits.

East Lachlan Fold Belt, NSW**:** Further drilling is set to commence on two target areas in the East Lachlan Fold Belt near Nyngan, NSW, with the objective of discovering intrusive-related porphyry copper-gold mineralisation within a large volcanic complex situated under younger cover rocks on the western edge of the Great Artesian Basin.

The two areas of potential interest, as indicated by previous drilling, have been surveyed with detailed geophysical gravity measurements. Interpretation of this work, combined with mineralogical studies from drill core, has resulted in the new series of drill targets for testing early the June 2012 quarter.

Discovery and Growth Outlook

In the June 2012 quarter, drilling will focus on the Gwalia mine trend and the East Lachlan project, NSW, whilst developing new targets in the Yilgarn Province, WA. The map below shows current and planned target areas for the remainder of FY12.

Health & Safety

The Total Recordable Injury Frequency Rate, calculated as a rolling 12 month average, increased from 11.9 to 12.7 at the end of the March quarter. The severity of injuries is decreasing.

Financials (unaudited)
