Jan 26, 2016 (A Wilson) - Sulphide mineralization occurs near the contact between pillow mafic metavolcanics and thinly-bedded intermediate to felsic tuff. This contact has been injected by gabbroic sills. Diamond drilling confirmed the presence of two mineralized zones, a southern pyrrhotite-pyrite rich, graphitic chloritic chert zone and a northern laminated graphitic chert with pyrrhotite. Several thinner sulphide mineralized cherty horizons are also indicated between the two zones.

Dec 07, 2005 (A Wilson) - Grab samples of the sulphide-bearing material assayed up to 0.49% Zn and up to 0.33% Cu. Samples of drill core returned values ranging from 57 to 3460 ppm Zn and/or 147 to 8170 ppm Cu. A single grab sample collected in 1980 returned an assay of 0.041 oz/t Au.
