The Sandon mill is a nominal 100 ton (90.7 metric tonne) facility. It is a standard crushing, grinding flotation system that produces a zinc and lead concentrate, as seen on the flowsheet diagram below. The mill has been in operation for numerous decades and has treated all the Silvana orebody, since 1971. Initially the mill ran on diesel power but is now hooked into the BC Hydro power grid. The concentrates were shipped by truck to the Teck Corporation Canada’s Lead Zinc Smelter facility in Trail, British Columbia which is 1.5 hours away from the mill. There is a licenced Tailings Management Facility that handles the waste from the mill. The mill is currently on care and maintenance until enough economic mineralization can be identified in and around the Silvana Mine.
