Antipa Minerals Limited announced that citadel project 2016 phase 2 drilling programme update no. 2 drilling identifies 4.8km copper system at Rimfire. The company said that 4.8km long copper mineralised trend identified at Rimfire, including the following intercepts: 23.0m at 0.12% copper in 16ACC0061 from 61.0m downhole; 25.0m at 0.09% copper in 16ACC0071 from 56.0m downhole; 18.0m at 0.10% copper in 16ACC0064 from 67.0m downhole; and Additional metal associations include silver, zinc ± tungsten ± lead. Rimfire trend considered highly significant for a reconnaissance style drilling programme and provides compelling targets for follow-up. Initial drill testing of Blue Steel and Meekus IP targets did not appear to discover either sufficient sulphide mineralisation or false positive indicators (e.g. black shale, etc) to explain IP chargeability anomalies. Follow up exploration required. Programme fully funded by Rio Tinto and further results to follow.
