Oct 27, 2017 (Therese Pettigrew) - Detailed mapping by Noranda in the area of the trenches on the shore of Brooks Lake indicate a mafic metavolcanic sequence intruded by a felsite or quartz porphyry sill no greater than 15 m in thickness. A unit of intensely altered rock (approximately 10 m wide) lies on the north flank of the felsic sill (AFRI 52F04NE0022). South of Brooks Lake, some pillow interstices are abnormally wide especially where pillow selvages are well developed. Calcite is a common filling of the interstices and where weathered out, has left individual pillows with high relief (Edwards, 1980).

Oct 27, 2017 (C Ravnaas) - Best assay: 4960 ppb Au from surface 0.157 oz/t Au.
Oct 27, 2017 (Therese Pettigrew) - Visible mineralization consists of up to 4% pyrite and trace chalcopyrite. Gold assays rarely exceeded 0.01 opt Au although 0.054 opt Au was recovered from one trench (AFRI 52F04NE0022).
