Co-O MINE CONCEPTUAL EXPLORATION TARGET ENHANCED BY DRILLING
24 August 2011
Medusa Mining Limited ("Medusa" or the "Company"), through its Philippines operating company, Philsaga Mining Corporation, advises that the release of the new resource model for the Co-O Mine and on-going exploration drilling results have significantly increased the support for the Conceptual Exploration Target ** for the Co-O Mine of:
3,000,000 ounces in 9,800,000 tonnes to 7,000,000 ounces in 23,500,000 tonnes using a grade range of 9 to 11 g/t gold with a preferred average grade of 10 g/t gold.
The combination of past production of approximately 450,000 ounces and the current global resource of 1,960,000 ounces indicates the deposit size is approaching the lower end of the Conceptual Exploration Target size range.
Detailed mapping and data compilation of the Co-O Mine vein system has been completed. It is a well preserved, intermediate sulphidation epithermal vein system with a large near surface, mushroom-shaped argillic alteration zone measuring over 1,500 by 1,500 metres in area and which grades into propylitic alteration to the east and at depth. The alteration and mineralisation trends indicate that the source of mineralising fluids is likely to be from beyond the current eastern end of the vein system.
