Bluebird Resource The Bluebird (including Bluebird North) deposit occurs as quartz-veins within a high-magnesium basalt host rock in a carbonate-altered shear zone. Mercator commissioned Cube Consulting Pty Ltd (Cube) to provide independent resource evaluations for Bluebird. At Bluebird the mineralisation is steeply dipping with plus 2g/t Au high-grade zones, with surrounding and proximal low-grade mineralisation based on a 0.4g/t cut-off. The resource figures are summarised in the table below: Total Bluebird Global Resource all gold within +0.4g/t Au wireframe Category Tonnes Gold g/t Metal (oz) Indicated 7,939,000 1.6 408,000 Inferred 2,253,000 1.9 138,000 TOTAL 10,192,000 1.7 546,000 The global Indicated resource has increased by 302,000 ounces from last year's Mercator announcement of 2.0Mt @ 1.6g/t for 106,000 ounces. These revised resources lift the Company's holding to over 2 million ounces, comprising Indicated Category 26.2Mt @ 1.7g/t for 1,401,000 ounces and Inferred Category 15.8Mt @ 1.5g/t for 759,000 ounces. The Company's combined Indicated and Inferred Resources are 42Mt @ 1.6g/t for 2,160,000 ounces. Evaluation and feasibility Mercator Gold is currently involved in detailed studies to determine the optimal mining parameters and economics for the Bluebird, Surprise and Paddy's Flat resources. These include studies on the metallurgical recovery, mining methods and scheduling of multiple sources of ore. Generally, the Company is assessing the potential for open cut mining above the 300 mRL (about 170m from surface) and underground mining potential on the deeper higher grade material from all its projects. The Company has commissioned a resource evaluation for Surprise which is expected in October, and exploration drilling at the PVC project at Paddy's Flat continues. Details of successful drilling at Surprise and PVC were given in the last technical press release issued on 8 August 2006. Managing Director, Patrick Harford, said: 'Bluebird and Surprise are important components in the development of our strategy of sustainable profitability. We look forward to the completion of our studies there and the integration of these resources into our overall production scheduling.'
