The metallurgical testing initiated by MacDonald Mines will investigate simple processing methods that require no chemicals to concentrate the gold and silver and achieve the highest possible recovery.

To evaluate multiple options the following will be completed:

-Head assays; -Mineralogical characterization of the feed; -Bond ball mill grindability test; -Heavy liquid separation testing; -Knelson concentrator testing; -Flotation and leach testing on gravity tailings as diagnostic tests.
