Geological reserves at the Stirling gold mine near Beatty, Nev., are reported by 52% owner Cathedral Gold (TSE) to be the highest ever in the mine’s 10-year operating history. Mine geological staff currently estimate that current geological reserves total 519,000 tons grading 0.21 oz. gold per ton, an 83% increase since 1987 when Cathedral acquired its interest in Stirling. The report is based on results from surface drilling and underground development.
To date, 72,559 oz. of gold has been recovered from 400,518 tons of ore by heap leach recovery methods. In 1989, the mine was changed from a combined open pit and underground operation to 100% underground operation.
This changeover is now complete, with the key feature in the transition being the development of an underground ramp to reach ore zones on three levels.
So far production rates have been on budget and on target and the mine is expected to recover more than 11,000 oz. gold this year. Minable reserves are deemed sufficient to sustain production at current rates for an additional six years.
