The ore is from cobalt Ontario, so I believe it is pure silver metal with cobalt arsenide, silver arsenide and nickel arsenide So I would avoid the hcl wash on my 100 mesh crush as it would convert too much silver to silver chloride, thus the silver chloride would burn off in the furnace. Thanks for the insight!
