Aug 21, 2015 (A Wilson) - Drilling by Newmont in 1983 outlined a northwest-trending carbonate zone in basalts on the south side of an ultramafic horizon and in association with a graphitic horizon.

Aug 21, 2015 (A Wilson) - Gold intercepts of 7.1 g/t Au over 1.5 m, 1.65 gt Au over and 1.65 g/t Au over 1.8 m were reported from the Newmont drilling. The Gowest drilling results confirmed and exceeded the historic 1980’s assays. Four gold mineralized zones were identified in DDH GW13-236, with the best gold zone returning 5.01 g/t Au over 4.4 m which included 12.00 g/t Au over 0.7. The wider upper gold zone is hosted within a pyritic sedimentary unit and the three other gold zones are in carbonated-silicified basalts. These three zones which includes the 5.01 g/t Au over 4.4 m are characterized by disseminated arsenopyrite-pyrite mineralization, which is a similar environment to that hosting the Bradshaw Gold Deposit. Two of the gold zones are open to the southeast and all the zones are open at depth below hole GW13-236 which penetrated the lowest zone at an estimated vertical depth of 240 m.
Aug 21, 2015 (R Pressacco) - DDH 255 - B81-1 intersected three zones of gold mineralization. The first zone was in the 410-422 foot interval and contained a weighted average grade of 573 ppb Au / 12 feet (0.017 opt Au / 12 feet). The mineralization was contained in the beginning of a larger interval of what the drill log described as bedded exhalite - Massive pyrite in chloritic-siliceous matrix where there appears to be a greater number of small quartz-ankerite veinlets. The second zone was in the 518-520.5 foot interval and contained a weighted average grade of 380 ppb Au / 2.5 feet. Again, the host seemed to be an exhalative chert bed. The third zone was by far the strongest and occurred in the 550-563 foot section which contained a weighted average grade of 2.16 g/t Au (0.063 oz./ton Au) / 13 feet. The drill log indicates that this zone was hosted mostly by a massive pyrite section, with some graphitic material. A follow up hole was drilled (DDH 255 - B81-4) to test for the down-dip extension of these mineralized zones, and that hole intersected an anomalous gold value of 400 ppb Au (0.012 oz./t Au) / 20 feet (837-857 feet). Again, this gold intersection appeared to be hosted by a massive pyrite section which contained a number of small quartz veinlets. A second follow-up hole in 1982, drilled some 300 feet to the west-northwest (DDH 255 - B82-1) also intersected a section of anomalous gold values that contained a weighted average grade of 785 ppb Au / 30.0 ft. (0.023 oz./ton). These gold values were hosted by what the drill log describes as pyritic-graphitic-tuff breccia and exhalative massive pyrite.
