Dec 12, 2012 (Scott Charbonneau) - 1901 - Assays averaged 27.2% arsenic and trace gold. 2011 - 3 samples assayed for gold and silver were all below the detection limit of 0.1 oz/ton Ag and 0.01 oz/ton Au.
Date: Jul 19, 2011
Geologist: P LeBaron
Notes: The deposit was visited on July 19, 2011. The shaft referred to in Wells (1902) was not located but a rock pile, with a location that corresponds well to the shaft location given in the reports, appears to be composed of waste rock from mining activity. The rocks consist of biotite-rich metasediments containing a few rusty quartz veins up to several cm wide. One seam of arsenopyrite about 5mm wide was observed in quartz-feldspar-biotite schist. Three samples were taken and assayed for gold and silver content by the OGS Geoscience Laboratories (fire assay).
