[{"type":"text","content":" VANCOUVER, British Columbia, March 14, 2019 (GLOBE NEWSWIRE) -- Kutcho Copper Corp. (TSXV: KC) (OTC: KCCFF) (“Kutcho Copper” or the “Company”) is pleased to provide an update to its metallurgical program based on work led by Mr. Len Holland of Holland & Holland Consultants, UK, an internationally recognized metallurgical consultant and Ausenco Limited, a multinational engineering company. Results to date suggest a simplified reagent suite that could achieve similar recoveries and concentrate grades, but at lower capital and operating costs compared to the 2017 Kutcho Prefeasibility Study (Please see the Company’s website www.kutcho.ca for the 2017 NI 43-101 Technical Report or SEDAR www.SEDAR.com) “The revised metallurgical program test results reveal potential for an important value addition to the Kutcho project,” said Vince Sorace, President and CEO of Kutcho Copper Corp. “The Kutcho team continues to identify opportunities to enhance the value of the project through previously reported resource increases, operational efficiencies through areas such as this enhanced metallurgical performance and progressing towards completion of the Feasibility study.” Optimization Program Kutcho’s team, led by Mr. Holland, identified an opportunity to improve on the historical metallurgical work conducted by previous owners of the Kutcho project. The Company has developed an improved reagent scheme based upon an optimized primary grind and standard zinc depressor reagents to obtain selectivity between the copper and zinc at a relatively high pH in the copper float. The flowsheet and reagent scheme presently developed is both simpler and lower operating cost when compared to previous proposed systems. In addition, lower levels of zinc reporting to the initial copper concentrate should assist in improving the overall zinc reporting to the zinc circuit. Grind parameters are typical of those used for polymetallic deposits similar to Kutcho, with a primary grind anticipated at 60 microns. A regrind on the copper rougher concentrate will be required and is presently anticipated as +/-25 microns, while the zinc circuit does not require a regrind. The 2017 Prefeasibility Study utilized life of mine average recoveries of 84.7% copper, 75.7% zinc, 48.0% silver and 41.2% gold, with the copper concentrate anticipated to grade 27.6% copper and the z...
