Jul 14, 2014 (A Wilson) - The Braminco 21 Vein is a complex vein system hosted within a 135-145° striking, high strain zone dipping 50-70 degrees to the southwest. The intense ductile schistosity is defined by sericite, biotite, quartz and feldspar and is superimposed on the regional fabrics. The Braminco #21 shear zone is 10-15 m wide and cannot be traced very far northwest or southeast of the open pit.

Jul 14, 2014 (A Wilson) - A 1984 plant scale test of 3000 tons of ore returned assays of 0.217 oz/t Au and 77.9% Si. Assays from drill holes completed in 1984 in the open pit area ranged from 0.061 oz/t Au over 36 feet to 1.41 oz/t Au over 30 feet. In 1984, Canreos drilled 4 holes to test the down plunge extension of the 21 Vein. These holes intersected 42 feet grading 0.121 oz/t Au.
