Executive Summary
This NI 43-101 Technical Report outlines the mineral resource and preliminary economic assessment for the US Grant Mine Property located in Virginia City, Montana. The report details the current operational capacity of the US Grant mill, which was constructed between 1975 and 1977. Currently, the facility processes 2 tons per hour via froth flotation to produce bulk and gravity concentrates.
The assessment includes plans for capital expenditure to commission a new grinding circuit, which is expected to increase throughput to approximately 6 tons per operating hour. The existing crushing plant is rated at 175 tons per day. Tailings disposal is managed through a pipeline to a lined impoundment facility with expansion potential and the use of underground stopes for cemented tailings storage.
All ores in the current mining plans are anticipated to be sulfide. A recovery rate of 91.0% for both gold and silver is assumed, based on results from the Dawson report and reinforced by tailings assay data from the 2016 mill commissioning.
