08/19/2019 (T Pettigrew) - At the showing location, due south of Center Lake, a grab sample from an outcrop of quartz- and sericite-altered quartz porphyry, containing disseminated pyrite, gave a value of 2870 ppb gold. A drill hole collared at this location by St. Joseph Exploration Ltd. intersected 1.5 m of quartz porphyry containing 5-10% pyrite-tourmaline veins and 350 ppb Au (Breaks et al., 1989).
