Kutcho Copper Recovers 94.5% Copper and 89.3% Zinc in Metallurgical Locked Cycle Test Results for the Esso Lens

VANCOUVER, British Columbia, Nov. 21, 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. These latest results show improved copper, zinc and silver recoveries, higher concentrate grades and improved separation of copper and zinc into their respective concentrates. 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.

Leading up to recent Locked Cycle Tests extensive mineralogical evaluations carried out on drill core composites by QEMSCAN have been completed and incorporated into block models to fully quantify and characterize the mineralization in terms of mineral abundance important to controlling metallurgical performance. The study allowed the Company to accurately define copper deportment and speciation (chalcopyrite and bornite) and pyrite content as well as head grades reflective of the Measured and Indicated resource grade. This gives the Company an added measure of confidence in the metallurgical results and their representation of the Esso lens.

The results were produced from a recent Locked Cycle Test completed on Esso lens material which is contemplated to be processed at a 50:50 blended ratio with Main lens material during the mid-years of production at the Kutcho Project. These results, in combination with those provided in the September 11, 2019 news release, demonstrate the robust nature of the developed Kutcho flowsheet.

The recoveries of copper and zinc to their respective concentrates have improved significantly over the 2017 Pre-feasibility study (PFS) Life of Mine (LOM) results, including improved zinc concentrate grades and the rejection of zinc from the copper concentrate, to generate a cleaner, higher value copper concentrate, as shown in the tables below. Silver recovery was also significantly improved.

“We are extremely pleased with the metallurgical performance from our composite from the Esso deposit. We are looking forward to including these improved results in our upcoming Feasibility Study, where we believe they will have a positive impact on the economics of the Kutcho project,” said Vince Sorace, President & CEO of Kutcho Copper.

The flowsheet utilized for the Esso material bench scale test work is the same simplified flowsheet utilized for the Main deposit as reported in the September 11, 2019 news release. A single stage of flotation cleaning has been used in the copper circuit and only two stages of flotation cleaning were required in the zinc circuit. The currently contemplated process plant design incorporates a primary grind size target of 75 microns K80. Regrinding was utilized in both the copper and zinc circuits with the copper cleaning circuit regrind being approximately 15 microns K80 and the zinc cleaning circuit did not require a regrind. The total mass of material which will be subject to finer grinding is less than 20% of the anticipated mill feed.
