Executive Summary
The Goynuk Mine has a history of artisanal production utilizing hand sorting and primitive gravity concentration methods to supply local antimony smelters. Underground mining operations were conducted from the 1970s through 2006, with ore hauled to the Metsan mill-smelter complex for milling, froth flotation concentration, and subsequent smelting.
The Metsan smelter is currently non-operational due to environmental reasons, necessitating that any future concentrates meet enhanced purity specifications for the international market. Wardell Armstrong International conducted beneficiation test work on Goynuk Mineralization samples, determining that stibnite recovery is amenable to both gravity and froth flotation techniques.
An optimal flow sheet cannot be determined until further exploration is completed and a mineral resource is established. Future processing may apply gravity and flotation procedures separately or in sequence, depending on ore size and grade characteristics.
