Winter 20 1 6 61 per million rhenium, plus 205.6 million tonnes in the inferred category. Red Dog would have a lower strip ratio and higher grade than the larger Hushamu, and the PEA will consider the economics of a separate starter pit. Advanced argillic alteration immediately to the south of a normal fault terminating Red Dog mineralization suggests a target at depth. Limited step-out drilling encountered grades that increased with depth. Lorraine Copper Corp. acquired 100 per cent of the OK Copper property and proposed drilling, pending an updated permit. Surface work will proceed in the interim. Most advanced of several targets is the North Lake zone, with a 2006 inferred resource of 86.8 million tonnes grading 0.31 per cent copper and 0.014 per cent molybdenite. Industrial minerals and aggregates Exploration at Electra Stone Ltd.'s Apple Bay quarry included percussion drilling to better characterize the deposit and the extent of high-silica material. Several private operators have begun or proposed bulk sampling of marble, dolomite and other products on Vancouver Island. Building and landscaping stone is also quarried in test operations under bulk sample permits on Vancouver Island and on the mainland. Most exploration for aggregate goes unreported, but Polaris Materials Corporation, a public company, makes its work known. Polaris drilled its Black Bear project, a potential source of crushed basalt south of its Port McNeill Orca sand and gravel quarry. Black Bear now has a measured and indicated resource of 70 million tonnes, and 330 million tonnes in the inferred category. The BURNCO Aggregate Project, a large proposed sand and gravel quarry, entered B.C. environmental assessment review in 2016. Peak production could exceed one million tonnes per year. BURNCO Rock Products Ltd. would barge product from the location on Howe Sound to facilities in the Lower Mainland. Deakin.indd 1 15-02-16 8:38 AM
