Calibre Mining
The Company has completed 21,500 metres of RC drilling on a 9 x 9 metre spacing. The results of this drilling demonstrate 29% more ore tonnes at a 1% higher grade for 30% more gold than the comparable area in the 2022 Mineral Reserve model at an ore-waste cut-off of 0.38 g/t gold.

A Pretreatment of Refractory Gold Ores Containing Sulfide
In this study, a new method to improve gold extraction from sulfide bearing gold ores is proposed based on the model experiments using a mixture of gold powder and arsenopyrite-bearing sulfide (HAsBS) ore. The effects of HAsBS ore on gold leaching in ammonium thiosulfate solutions were investigated, and it was found that gold extraction in the ...

Descriptive models for epithermal gold-silver deposits
Epithermal gold-silver deposits are vein, stockwork, disseminated, and replacement deposits that are mined primarily for their gold and silver contents; some deposits also contain substantial resources of lead, zinc, copper, and (or) mercury. These deposits form in the uppermost parts of the crust, at depths less than about 1,500 meters below the water table, and at temperatures …
