Bisha Looks Forward to Significant Reserve and Production Expansion

Bisha Mining Share Company is pleased to advise on growth strategies for reserves and throughput for the Bisha project in Eritrea. The Bisha gold phase remains on time and on budget, with commissioning expected in Q4 2010 and commercial production in Q1 2011.

Reserves

Bisha’s 20 million tonne reserve is expected to increase as a result of the following opportunities:

  • Revising reserve calculations for updated metals prices and lower cut-off grades. The existing reserve was determined using outdated cut-off grades and metal prices. Recalculation could potentially convert what was previously considered waste to ore;
  • Converting inferred resources below the feasibility study pit to reserves by infill drilling;
  • Definition drilling of the hanging wall copper mineralization, directly adjacent to the Bisha deposit, to estimate additional resources and potential reserves; and
  • Infill drilling the Harena discovery, which is 9km south west of Bisha, to perform a resource and reserves estimate.

Bisha’s 20 Mt reserve is part of a 27 Mt measured and indicated and 12 Mt inferred resource, indicating substantial opportunity for growth. The extent of reserve expansion is not yet fully determinable but the Company anticipates the above activities should significantly enhance total reserves within the next year.

Production

The Company plans to design the copper phase with throughput rates of 20% to 40% higher than the 2 Mt per year modeled in the Bisha feasibility study. Detailed design for the copper phase is starting in the next quarter with copper phase production scheduled for early 2013.
