Jun 10, 2010 (A Wilson) - The prospect is described as an atypical quartz-carbonate-chalcopyrite-pyrite cemented, vein breccia within the Gowganda Formation. Carbonate minerals include ankerite and siderite. The breccia fragments consist of silicified and hematized quartzite that are strongly aligned in a north-south trending zone that dips approximately 55° to the west.

Jun 10, 2010 (A Wilson) - Samples in the trench over a length of 30 feet and a width of 10 feet averaged 2.54% Cu. Assays from drill holes completed by Frobisher Exploration returned the following values: 4.14% Cu over 0.5 feet and 3.72% Cu over 1.1 feet from drill hole 8. One drill hole completed by Bruce Presto Mines reportedly cut 179 feet of mineralized breccia. Within this length two sections assayed 1.44% Cu over 12 feet and 3.97% Cu over 17 feet.
