[{"type":"text","content":" VANCOUVER, British Columbia, Sept. 11, 2019 (GLOBE NEWSWIRE) -- Kutcho Copper Corp. (TSXV: KC) (OTC: KCCFF) (“Kutcho Copper” or the “Company”) is pleased to announce results of ongoing metallurgical testing on its 100% owned Kutcho Project in British Columbia, Canada. This test program is part of the work completed or underway that is designed to support completion of a Feasibility Study for the Kutcho Project. The results were produced from recent Locked Cycle Tests completed on composites representing a range of proposed process plant feed material characteristics found within the Main Lens of the Kutcho Project, including sulphur content, copper grade and copper mineralogy. The 2019 Kutcho Composite “A” compares favourably with the updated 2018 Measured and Indicated resource in terms of both precious and base metal grades and total sulphur (pyrite content) which more closely approximates the known average sulphur content and respective metallurgical response. Composite “B” represents complex material containing higher sulphur content (as pyrite) compared to the updated resource model. Material tested is originated from the 2018 infill drill program from the Main lens and represent the current bounds of understanding for the Kutcho Project. The recoveries of copper and zinc to their respective concentrates have improved significantly over the 2017 Pre-feasibility (PFS) Life of Mine (LOM) results including improved zinc concentrate grades and the rejection of zinc from the copper concentrate, as shown in the tables below. Silver performance was also significantly improved. Selected copper and zinc concentrates produced from the 2019 cycle tests were analysed for minor trace metallic elements and were found to be free of impurities which would typically attract smelter penalties. 2019 Locked Cycle Test Results Main Lens Composite A Product Weight Grade Recovery (%) Cu (%) Zn (%) Au (g/t) Ag (g/t) Cu (%) Zn (%) Au (%) Ag (%) Cu concentrate 7.5 26.6 4.7 2.8 347 92.3 9.7 36 71 Zn concentrate 5.1 0.9 59.7 2.1 84.2 Feed (Composite A) 100 2.2 3.6 0.6 37 100 100 100 100 Main Lens Composite B Product Weight Grade Recovery (%) Cu (%) Zn (%)...
