Four samples of ~5lbs each were taken from alternating supersacks, as part of a 20 ton test shipment, and assayed by ALS Global, North Vancouver, BC using fire assay method Au-AA25:

Development was undertaken in the area of a recent discovery (June 2025) of massive sulphide surface outcrop with gold assay of 0.5 ounces per ton. The massive sulphide surface zone is between trenches of prior known high grade gold mineralization in Trench B and Trench C, to the West and East respectively, with grade increasing at depth. The ore is heavily mineralized containing gold, copper, and silver mineralization primarily in the form of chalcopyrite, marcasite, and spherulite/galena. The massive sulphide ore is grey in color, blocky when broken with visual mineralization, veinlets, and sheeting. Grade has been confirmed in the above reported assay as well as previous assays in Trenches B + C up to 2.3 ounces per ton gold. Approximately 20 tons of ore has been extracted, packed into supersacks, loaded and shipped to the Company's Bishop Gold Mill.
