Sep 30, 2019 (Therese Pettigrew) - The original showing was described as a rusty shear zone, greater than 25 feet in length and 6 feet in width, hosted in mafic metavolcanic rocks. The shear zone hosts an intricate network of ankerite stringers with common calcite segregations. Along the hanging-wall side of the zone are irregular masses of quartz up to 6 inches in width. In the middle of the zone is a lens of siliceous vein material that is 6 to 12 inches in width and 20 feet in length and hosts arsenopyrite as well as pyrite and galena. A grab sample of this material yielded 0.08 ounce of gold per ton (Laird, 1937). Grab samples collected by Houghton and Lassila in 1994 returned assays between 0.1 and 0.2 ounce of gold per ton. Samples collected by Gunnex in 1971 returned values up to 0.16% Cu and 0.05% MoS2 (Assessment report 52H09NE00180).
