The new reserve estimate, which is based on a gold price of US$375 per oz., adds 161,000 oz. to the projection contained in the bankable feasibility study. The waste-to-ore ratio has decreased 20% to 3.1-to-1, thereby improving the economics of the proposed mine.
Recent drilling has increased the resource by 22% in the measured and indicated categories to 28.8 million tonnes grading 2 grams gold per tonne. In the inferred category are 509,000 oz., which will be the focus of infill drilling.
The project was awarded an environmental permit in April, as well as a 15-year mining lease that covers 36.3 sq. km.
