Colt Resources Receives Positive Metallurgical and Drilling Results at Tabuaço Tungsten Project, Northern Portugal
surrounding area believed to host the most significant upside potential. As part of its ongoing efforts to advance the Tabuaço deposit towards production, the Company had previously submitted a 522 kilogram representative sample of metallurgical drill core to a Chinese metallurgical services provider for process testing. A final report of this investigation has been issued by the Chinese metallurgical services provider, demonstrating a process flowsheet that includes flotation followed by acid leaching achieved 87.2% overall tungsten recovery into a final concentrate containing 70.65% WO3 from an ore sample containing 0.64% WO3. The Company is very pleased with the results of this test work as it demonstrates a high tungsten recovery, by world standards, into a premium grade scheelite concentrate. The Company plans to conduct pilot mill testing on approximately 20 metric tons of ore from Tabuaço later this year. The Company also intends to investigate further the potential production of fluorite concentrate as a possible by-product from the deposit.
