Executive Summary
This Technical Report and Feasibility Study for the Back River Gold Property, prepared for Sabina Gold & Silver Corp., outlines a 10-year mine life project located in the Kitikmeot Region of Nunavut, Canada. The project involves a combination of open pit and underground mining operations targeting multiple deposits including Umwelt, Llama, and Goose Main. The proposed processing facility is designed with a nominal capacity of 6,000 tonnes per day, treating ore with an average feed grade of 5.70 g/t gold. The study confirms positive economics warranting development, utilizing a whole ore cyanide leach and carbon adsorption flowsheet.
The processing plant design includes primary and secondary crushing circuits, followed by a two-stage grinding circuit comprising a ball mill and a fine grind mill. Gold recovery is achieved through gravity concentration of cyclone underflow, intensive cyanidation of the gravity concentrate, and bulk cyanide leaching with carbon-in-pulp (CIP) adsorption. The project infrastructure is heavily reliant on a Winter Ice Road connecting the Marine Laydown Area at Bathurst Inlet to the mine sites, as well as a Marine Laydown Area for sealift logistics, due to the remote Arctic location.
Key operational parameters include a 93.3% overall gold recovery and a mine life of 10 years. The report details significant infrastructure requirements including power generation, water management, and waste rock storage, all designed to operate in continuous permafrost conditions. Closure and reclamation plans are integrated into the design, with tailings to be deposited in mined-out pits and the initial TSF covered with waste rock. The study concludes that the project has positive economics and warrants development, though financing challenges were noted leading to a conceptual reduced CAPEX option.
