Jun 02, 2017 (A Wilson) - A 0.6 m section of drill core returned 1735 ppm Zn and 167 ppm Cu, 119 ppb Au from 72.54 to 73.15 m (MacDonald Mines press release July 29, 2004).
Jul 25, 2014 (Therese Pettigrew) - 2004 drill program results: BM-7 intersected magnetic grey green ash and tuff with occasional quartz veins, minor sulphides, and massive, bedded pyrrhotite with trace sphalerite (0.7 m averaging 0.27% Zn and trace Cu) from 100.6 to 102.7 m. Vanadium-bearing titaniferous magnetite with commercial vanadium grades occur as thick layers in differentiated mafic-ultramafic sills that underlie well-bedded VMS-hosting ash tuffs (Kretschmar, 2005 – AFRI 2.31529).
