[{"type":"text","content":" MONTRÉAL, April 24, 2019 (GLOBE NEWSWIRE) -- Kintavar Exploration Inc. (the “Corporation” or “Kintavar”) (TSX-V: KTR) (FRANKFURT: 58V), is pleased to announce the results of its preliminary metallurgical test work for samples from drill hole MS-18-36 in the Sherlock area of the Mitchi project in Quebec, Canada. The objectives of this test work are to demonstrate that the Sherlock mineralized materials are amenable to the production of high-grade copper concentrates using traditional mineral processing techniques. Results demonstrate that a very high-quality copper concentrate of up to 59% copper, and without any deleterious metals, can be produced, well above the global average of 25% copper1 and above the 32% copper concentrate often required to obtain a premium on concentrates. Recoveries of up to 80% were achieved and it is believed that it should be possible to increase the recoveries to the global average of 84%1 or above after performing additional optimization and testwork. Test work has been completed at ALS Metallurgy in Kamloops, British Columbia and supervised by Novopro Projects, Inc. from Montreal, Quebec, both independent of Kintavar Exploration. Test work followed industry standard methods and procedures commonly used for the design and development of copper recovery processes, including mineralogy, Bond Work Index testing, flotation testing and assaying of metallurgical products. One NQ diamond drill hole was drilled in the Sherlock zone, specifically to obtain representative material for use in metallurgical testing. Three main metallurgical composites were prepared from whole core obtained from this drilling and the composite samples are outlined in Table 1.

Pyrite occurs in trace amounts of below 0.1% allowing flotation to be easily performed. As the primary copper bearing minerals are bor...
