Bunker Hill Mining Corp has shipped the first concentrate from its Bunker Hill zinc-lead-silver mine in Idaho to Teck Resources’ integrated Trail lead-zinc smelter in British Columbia. The company’s new 1,800 t/d processing plant has completed commissioning and begun producing concentrate, marking the mine’s first concentrate-sale revenue in more than 45 years.

Bunker Hill is continuing to optimise plant performance during commissioning and is targeting full commercial production by year-end. Concentrate is analysed by Silver Valley Analytical before being trucked about 220 km to Trail for processing under Bunker Hill’s offtake arrangements. The restart introduces a new source of zinc-lead concentrate supply, while ramp-up performance remains the key item to monitor.
