A recent drilling program by Minerex Resources (TSE) increased minable reserves at the Aurora Partnership gold mine near Hawthorne, Nev. The project is owned equally by Minerex and Electra North West Resources (VSE).
The contained ounces in the updated minable reserve represents a 12% increase from previous reported reserves, and will allow production through the second quarter of 1993 and leaching through 1994.
The reserve increase came about after a 16,000-ft. drill program confirmed the extension of the Humboldt vein system to the east, beyond current open pit limits and on to ground acquired last year adjacent to the heap leach operation.
As a result of the successful program, minable reserves are now reported as 576,000 tons grading 0.14 oz. gold per ton, which includes a higher-grade component of 110,000 tons averaging 0.30 oz. gold per ton. Minerex said the higher-grade ore is being stockpiled to allow the use of higher recovery processing later this year.
The Aurora Partnership property also contains preliminary reserves of 1.7 million tons grading 0.11 oz. gold outside the current minable reserve. This includes a higher-grade core of 168,000 tons at 0.32 oz. gold. Studies are in progress to determine the economic feasibility of extracting a portion of this reserve by alternate mining methods, including underground. More drilling is also planned for this year to further delineate additional reserves.
Minerex is a Vancouver-based junior owned 50.5% by Canada Tungsten Mining (TSE). The company is also seeking new mining opportunities, primarily in the Western U.S.
