Feb 28, 2018 (Therese Pettigrew) - While prospecting north of Cloud Bay, Kwiatkowski reported finding nuggets of native copper in gravel found in a major fault cutting through a diabase. The dyke runs for several kilometers and is cut by a fault zone 50 m wide and trending about 80 degrees north. The copper nuggets were found in the gravel bed at the western extremity of the dyke. Assays on three samples returned values of 1200 ppm (0.12%) Cu up to 36.992% Cu (AFRI 52A03SW8101).
