A subsequent 1,200-kg mineralized pattern was taken over a 3-metre strike size and assayed 55.6 g/t native gold.
Granada has additionally despatched a 100-kg pattern to Gekko in Australia to check whether or not it may be upgraded utilizing in-line strain jigs. The expertise has the potential to pre-concentrate low grade ore, and it could be helpful in treating ore from the mine.
Granada president and CEO Frank J. Basa stated in a launch, “Based mostly on outcomes from this bulk pattern and the Gekko pre-concentration check outcomes, the corporate could rethink the useful resource grades and return to the unique 43-101 historic in situ mineral sources of 946,000 oz. gold at 1.02 grams per tonne measured, 659,000 oz. gold at 1.09 g/t indicated and 1,033,000 oz. gold at 1.07 grams per tonne inferred. A cut-off grade 0.4 grams per tonne gold was used.”
The useful resource estimate made in January this included 12 months each pit and underground blocks. Within the potential pit there are 5.1 million measured and indicated tonnes averaging 2.06 g/t gold for 339,000 contained oz. and 34,000 inferred tonnes at 11.29 g/t for 12,000 contained oz. Underground there are 844,000 measured and indicated tonnes averaging 4.03 g/t gold for 109,000 contained oz. and 1.2 million inferred tonnes at 6.33 g/t for 253,000 oz.
The Granada mine produced 51,476 oz. of gold within the Thirties from ore grading 9.7 g/t gold.
