MIITEL NICKEL MINE

MIITEL NICKEL MINE Production
The Miitel Mine had another successful year, with production tonnages near record highs and some 6.7% higher than the previous fi nancial  year, albeit at generally lower grades. The high production tonnage was the result of the progressive move from Central Miitel to North Miitel as the primary source of production. Production was also enhanced through the use of more productive equipment and mining methods. The overall lower grades were partly the result of a deliberate strategy to maximise production during a period of exceptional nickel prices, and partly the result of mining in generally lower grade portions of the ore body.

During the year Miitel’s total production since start of mining passed the 40,000 tonnes of nickel-in-concentrate mark, confi rming it as one of
the more signifi cant producers in the Kambalda Nickel District.

Mining progressed throughout all areas of the North Miitel ore body. Ore was won from development, mechanised fl at back cut and fi ll and long-hole stoping in the N11, N14, N19 and N25 ore bodies. The development of the twin declines at North Miitel continued, providing access into the northern sections of the North Miitel trend. At times the decline was put on hold to allow drilling beyond the northern limit of the published ore reserves. This drilling successfully located substantial additional mineral resources.

As at 30 June 2007, approximately 419,000 tonnes @ 2.6% nickel for 10,800 tonnes of nickel in ore had been mined from North Miitel. Approximately 535,000 tonnes @ 2.5% nickel for 13,600 tonnes of nickel in ore remain in reserves. This compares to the original reserve calculated in the North Miitel feasibility of 464,000 tonnes @ 2.7% nickel for 12,300 tonnes of nickel in ore.

MIITEL NICKEL MINE Costs
Cash costs per pound nickel are presented in Table 1 (page 8). Cash costs per pound nickel increased from last year due to higher input costs, higher royalties due to higher nickel prices and lower grades as outlined above. Direct costs per tonne of ore averaged $160 per tonne (mining, administration, trucking, milling, excluding royalties), a rise of around 9% on comparable fi gures for the previous year. This rise refl ects across-the-board increases to all inputs, especially in fuel and contractor mining costs. Increases in the cost per tonne were partially mitigated by employing higher productivity equipment and mining methods.

MIITEL NICKEL MINE Drilling
An ongoing program of underground drilling continued throughout the year. Much of this was carried out at the northern extremity of North
Miitel and beyond the northern boundary of the North Miitel reserve. This work produced a substantial extension to the mineral resource and ore reserves. The resource remains open to the north and down-plunge, as well as to the south.

Resources and Reserves
Resources and Reserves were recalculated for Miitel as at 30 June 2007, and these fi gures are shown in Tables 6 and 7 (pages 22-23). The original ore reserve at Miitel (on which the project was evaluated, acquired and fi nanced) was 844,000 tonnes @ 3.96% nickel containing 33,422 tonnes of nickel. At the end of June 2007, a total of 1,461,466 tonnes @ 3.29% nickel containing 48,028 tonnes of nickel in ore had been mined and delivered to the Kambalda Mill from Miitel/North Miitel. As at the end of June 2007, Miitel’s ore reserve is estimated at 983,000 tonnes @ 2.5% nickel containing 24,800 tonnes of nickel in ore. When added to ore already mined, this brings the total of mined and unmined ore reserves to 2,444,000 tonnes @ 3.0% nickel containing 72,800 tonnes of nickel in ore, an 118% increase over the original ore reserve.

Future Developments
In the coming year, effort will focus on stoping the already developed N11 ore surface, developing and stoping the N25 ore surface, and developing the N26 ore surface. The decline will be extended to the north in order to access the northern extremities of the current reserve and to allow drilling beyond this to explore for additional mineralisation. Development will also continue towards the South Miitel ore body, with access to and production from that ore source scheduled for the last quarter of the fi nancial year.
