Gold mineralization also occurs locally in this area associated with arsenopyrite.The core sampling will include intervals with arsenopyrite mineralization for gold analysis and intervals with base metal sulfide mineralization for base metal and silver analysis. The Elmtree 12 vein system includes local high-grade veins, including a 2018 drill intercept (hole Ky-18-14) of 1,158 grams / tonne (g/t) silver, 9.04% zinc and 9.19% copper over 3.00 meters core length.The 2021 drilling program, conducted within the northwest region of the Keymet Property, consisted of ten holes (2,661 total meters) testing numerous targets northwest of the historic Keymet Base Metal - Silver Mine.
