Dec 07, 2005 (K R Kettles) - This area is underlain by serpentinized and carbonatized ultramafic rocks of the Pipestone Bay stock. The ultramafic rocks contain roof pendants of mafic lava and felsic pyroclastic rocks. Foliations strike approximately N60 degs E and have a sub-vertical dip. There is a 60 m wide auriferous zone on the shore of Pipestone Bay that strikes roughly parallel to foliation. This zone consists of carbonatized ultramafic rocks that 'show considerable mineralization and small quartz stringers (Shaw, 1930). Some free gold occurs in these stringers.

Mar 23, 2012 (K R Kettles) - There is a 60 m wide auriferous zone on the shore of Pipestone Bay that is roughly parallel to foliation at N60 degs E and a sub-vertical dip.The carbonatized peridotite shows considerable mineralization and small quartz stringers which contain gold, silver, platinum and minor nickel. Assays from 1929-30 consist of the following: .12 opt Au, .02 opt Pt, .31% Ni over an unknown width; 1.88 opt Au, .03 opt Pt, and 0.29% Ni over an unknown width; .01 opt Au, 0.3opt Ag, and .47% Ni over an unknown width. Other assays for gold range from .17 opt Au/1.8m, .68 opt Au/1.8 m, 1.87 opt Au/1.8 m, .38 opt Au/7.3 m, .12 opt Au/1.2 m, and 0.11 opt Au in a grab sample. 2008 Sample 422858 returned a value of 6.21 g/t Au, This sample 1-2% pyrite.
Oct 14, 2020 (Therese Pettigrew) - In June 2000, reconnaissance sampling identified a number of semi-massive, chalcopyrite, pyrrhotite, pyrite rich blast rock, within the old blast pile. A total of 9 samples were collected during this program. Three samples returned copper values greater than 2000 ppm (2180 ppm, 2550 ppm and 3600 ppm Cu) (Assessment report 52M01SE2009).
Dec 07, 2005 (K R Kettles) - The ultramafic rocks in the auriferous zone are carbonatized, and are serpentinized throughout the area.
