Aug 16, 2019 (Therese Pettigrew) - Satterly (1939) described the showing as a highly silicified and heavily mineralized zone in dacite porphyry on the shore of the Northwest arm of Sandy lake on claim Pa. 3,241. The sulphide is pyrite, which occurs as coarse splashes, and the width of the zone is approximately 10 feet. A grab sample of this material assayed 0.01 ounces of gold per ton. At RvG4, two patches of irregular quartz veining and silicification occur within a carbonate-rich shear zone which trends approximately 140 degrees and dips subvertically. Gold values at RvG4 are associated with discrete quartz tourmaline veining, hosted by variably altered quartz crystal tuff. Bleached alteration haloes around the veins host weakly to highly anomalous gold values. Veins are relatively narrow (0.1 to 0.5 metres), however multiple vein sets are common. Pyrite is the dominant sulphide mineral at RvG4, with only traces of pyrrhotite. Channel samples taken in 2013 returned values of 16.9, 25.2, 41.1, 3.06, and 24.9 g/t Au. Diamond drilling by Goldeye Explorations Ltd. in 2013 returned 23.15 g/t Au over 3.97 m (Assessment report 20000008751).
