Dec 07, 2005 (K R Kettles) - This area is underlain by siliceous dolomite marble that strikes N50 degs W and dips steeply to the north. There are some felsic tuffs interlayered with these chemical sediments. Cross-sectional drilling in late 1945 encountered gold values over 4.27 m of drill core. The gold is hosted in a very siliceous portion of the chemical sediments. Gold was associated with pyrite, biotite, and chlorite.

Mar 23, 2012 (K R Kettles) - Gold is hosted in a very siliceous portion of the chemical sediments. The gold was found in association with fine-grained pyrite, biotite, and chlorite. Gold occurs in a stratabound pyrite-rich layer 4.27 m thick, in chemical sediments.Gold values encountered, 1945, between 105.03 m and 109.30 m in ddh #19: 105.56-107.77 M assayed 2.49 opt Au initially and 3.26 opt Au on re-assay. GRADE 1972 - 2 DDH;S TO NORTHEAST: LESS THAN 0.005 OPT AU. 2003. Goldcorp took multiple samples, highest assay returned 4.91 ppm Au
Sep 30, 2020 (Therese Pettigrew) - DDH PB12-032 returned up to 0.874 ppm Au over 1.01 m from pyrite-filled fractures, and 0.847 ppm Au over 1.05 m from a magnetite-bearing dolostone with pyrite stringers. BIFs at the bottom of the same hole returned up to 0.667 ppm Au over 1.85 m. DDH BL12-033 returned up to 0.851 ppm Au over 1 m from a contact between a sandstone and dolostone (Assessment report 20000009268).
Dec 07, 2005 (K R Kettles) - The host rocks contain biotite, and chlorite, and may possibly be silicified.
