[{"type":"text","content":" MONTREAL, May 08, 2019 (GLOBE NEWSWIRE) -- Osisko Metals Incorporated (the “Company” or “Osisko Metals”) (TSX-V: OM; OTCQX: OMZNF, FRANKFURT: 0B51) is pleased to announce excellent results from pre-concentrating test work on material sorters, including X-Ray Transmission Material Sorting and Dense Media Separation, on representative composite samples from the Pine Point project in the Northwest Territories, Canada. Conventional flotation test work is also ongoing on the material sorter pre-concentrates to validate and compare with recoveries from the historical Cominco Ltd. operations. The purpose of the pre-concentrating test work is to evaluate potential, near-pit cost saving measures related to transportation and processing of mineralized material to a projected mill. Salient results are summarized below: For X-Ray Transmission Material Sorting (“XRT”): Zinc recoveries ranged from 76.5% to 98.0% (average of 92.6%) Lead recoveries ranged from 94.9% to 99.7% (average of 97.8%) Mass pull* ranged from 34.4% to 73.5% (average of 49.1%) Average grade of rejected material is 0.75% Zn and 0.047% Pb For Dense Media Separation (“DMS”): Zinc recoveries ranged from 76.7% to 96.2% (average of 92.4%) Lead recoveries ranged from 87.4% to 98.7% (average of 95.3%) Mass pull* ranged from 12.8% to 61.5% (average of 30.4%) Average grade of rejected material is 0.75% Zn and 0.08% Pb * Mass pull is a measure of the weight percentage of material mass recovered from the pre-concentration test, hence the smaller the number the higher the savings in transportation costs and processing volume to the projected mill. Results indicate similar recoveries for both processes, but XRT is the preferred process as the end product is expected to be dry and easier to handle in northern weather conditions. Furthermore, machinery necessary for near-pit XRT sorting is also more mobile than DMS equipment, providing more operational flexibility to the future operation. Jeff Hussey, P. Geo., Osisko Metals President and CEO, stated: “This round of test work expands upon previous material sorting studies and conclusively confirms Pine Point material is amenable to XRT pre-concentration. Indications are that roughly half of the waste rock material can be rejected near potential pit operations with less than 10 percent loss of both zinc and lead mineralization. The benefi...
