Lithology Comments

May 18, 2017 (C Ravnaas) - The host rock is a mafic to ultramafic intrusive (Kakagi Sill #1). In this area a zone of weak vertical shearing (with a 10 cm 'core' of strong shearing) was encountered with accompanying silica, chlorite, iron carbonate alteration and disseminated pyrite from 3 to 10%. This shear strikes at 163° (width unknown) and was witnessed for at least 100 meters.

Mineralization Comments

May 18, 2017 (C Ravnaas) - Seven grab samples were taken by Cunniah Lake Inc.. Five of these samples returned values from 17 to 46 ppb Au, while two samples that contained 8 to 10*56 pyrite returned Au values of 2,325 and 2,056 ppb.

Oct 27, 2017 (Therese Pettigrew) - Beard and Garratt (1976) describe the Burnt showing as narrow quartz veins in diorite. The No. 3 vein is 8-10 cm wide and was traced over 488 m. Several grab samples ran from 0.16 to 0.63 opt Au with one sample of 2.02 opt Au. In 1945, H. Byberg obtained an assay of 0.98 opt Au from a grab sample of a very narrow quartz vein (AFRI 52F05SW0076).
