Jan 12, 2015 (D Draper) - A 0.5ft interval in acidic pyroclastics at 417ft in drillhole B-21 returned an assay of 0.51 opt Au from a section described as Highly silicified and seriticized with pyrite in powdery fracture fillings and as grains and cubes...carries granular brassy pyrite and a narrow irregular streak of chalcopyrite tarnished to peacock colours. Besides these there are two or three minute grains of bright yellow mineral that has not tarnished and is possibly visible gold.
