Taseko Mines Limited announced that it has submitted the Aquifer Protection Permit amendment application to the Arizona Department of Environmental Quality. The APP is one of two key permit amendments which are required for commercial production at the Company’s Florence Copper Project. The permit amendment application for the Underground Injection Control Permit will be made to the US Environmental Protection Agency in the coming weeks. Mr Russell Hallbauer, CEO of Taseko, said that “This past week, after roughly six months of operating the test facility, the leach solution reached commercial grade levels, well in advance of our anticipated timeframe. Based on previous bench-scale testing, we expected it would take upwards of a year to reach target solution grade, so we are obviously extremely pleased to have achieved this milestone after such a short period of time. The grade of the leach solution coming from our main recovery well is approximately 1,600 parts per million of copper in solution and would be comparable to a typical open pit, low cost heap leach operation. The main difference between Florence Copper and other leach operations is that we have no mining costs associated with our in situ leach process, making Florence Copper when in commercial operation, one of the lowest cost operations globally.”

Mr Hallbauer said that “The main focus of the test facility, beyond ensuring we achieve all the technical targets of our feasibility study, will be building our on-the-ground operational experience to streamline the transition to commercial production. Based on the knowledge we have gained in the last six months, the benefits of the two phase approach (production test facility followed by the commercial facility) will significantly improve the ramp up of the final commercial scale operation.”
