Osisko Metals releases exceptional flotation test work results at Pine Point

7 August 2019

Osisko Metals Incorporated is pleased to announce preliminary flotation test work results from the Pine Point Project in the Northwest Territories, Canada. These results were obtained from testing representative drill core samples from the 2018-2019 definition drilling campaign that were pre-concentrated using an X-Ray Transmission (“XRT”) material sorter. The resulting concentrate was analyzed for lead and zinc as well as a suite of deleterious elements typically associated with smelter penalties.
Results from the optimized cleaner testwork are as follows:
•Zinc recovery ranged between 93.1 to 94.5% 
•Lead recovery ranged from 87.4 to 91.4%
•Zinc concentrate grade ranged between 63.6 to 64.1% Zn
•Lead concentrate grade ranged between 67.9 to 72.1% Pb
•Zinc concentrate is significantly below penalty thresholds for all deleterious impurities except MgO, which is at threshold limits
Jeff Hussey, P. Geo., Osisko Metals President and CEO, commented: “These preliminary results are outstanding and confirm that the zinc concentrates originally produced at Pine Point were amongst the cleanest in the world. Using conventional flotation, we were able to achieve exceptional recoveries as well as concentrate grade and quality. We do not anticipate any smelter or refinery penalties should Pine Point go into production. We believe the Pine Point zinc concentrate would be a premium blending product in the zinc concentrate market which is forecasted to be dominated by much lower quality concentrates.”
Robert Wares, P. Geo., Osisko Metals Executive Chairman, also commented: “I am very impressed by these initial test results – quite frankly the best I have seen in my career. The Pine Point deposit is growing into a major zinc project with significant near-surface resources, excellent concentrate grades and recoveries, ready access and existing infrastructure, all within a safe Canadian jurisdiction. We expect to expand the resources this year with additional drilling that will be underway by the end of this quarter.”
