Oct 18, 2013 (A Wilson) - The mineralization occurs in a 3 cm wide quartz vein within the shear zone. This vein contains 1% euhedral pyrite together with hematite, goethite and jarosite. Sparse disseminated pyrite occurs adjacent to the vein within the sheared granodiorite. The best assays returned by Gogama Minerals were 1.12 g/t Au and 9.4 g/t Au.
