Sep 25, 2018 (Therese Pettigrew) - Sulphide mineralization (pyrite and chalcopyrite) occurs within both the diorite and metasediments within quartz stringers, fractures, quartz-filled diorite breccia zone, and as scattered disseminated grains (AFRI 52B10SW2015).
Dec 14, 2016 (Q Unknown) - Quartz veins and silica flooded shear zones in metasedimentary rocks assy up to 5.2% Cu and 4.08 g per t Au. Stripping has exposed shearing and mineralization for up to 2 km and a 2m wide quartz vein assayed up to 7.13% Cu, 1.11 g per t Au and 62 g per t Ag. Drilling yielded returned 0.52 gpt Au, 31.8 gpt Ag, 1.75% Cu over l meter.
