Feb 17, 2011 (A Wilson) - Diamond drilling intersected a sequence of mafic metavolcanic rocks, amphibolite, and intermediate metavolcanics. The drill hole terminated in andesitic rocks. The sequence is intruded by feldspar porphyry and gabbro.

Aug 01, 2014 (A Wilson) - Elevated copper values were returned from amphibolite lying above and below the gabbroic intrusion. A 0.5 m section of silicified biotite amphibolite returned 2540 ppm Cu and 230 ppm Ni from above the gabbro and a 1.4 m section of biotite amphibolite from below the gabbro returned 3590 ppm Cu and 699 ppm Ni. Sulphide mineralization within the hole includes pyrite, chalcopyrite and pyrrhotite. Most of the mineralization occurs within the biotite amphibolite as mm-scale wisps oriented with the unit somewhere between 45" and so· to the core axis. The highest concentrations of sulfides occur between 81.9 and 88.7 m. There are two quartz veins within the amphibolite, the veins preceded the amphibole alteration. They contain pyrite and chalcopyrite at about 3% over a 20 cm interval. Below that there is a 1.S m thick silicified zone containing 25% pyrrhotite and 5% chalcopyrite. The silicification came after the amphibolite. At the end of the hole, from 99-99.4 m there is a quartz vein with a 4 x 5 cm concentration of pyrite with minor chalcopyrite.
