About Osisko Metals
Osisko Metals is a Canadian exploration and development company creating value in the base metal space with a focus on zinc mineral assets. The Company controls Canada’s two premier historical zinc mining camps:

The Pine Point Mining Camp (the “PPMC”), located on the south shore of Great Slave Lake in the Northwest Territories, is located near established infrastructure, has paved highway access and has 100 kilometres of mine haulage roads and power substation already in place. The PPMC currently hosts an Inferred Mineral Resource of 38.4 Mt grading 4.58% zinc and 1.85% lead, making it the largest near-surface, pit-constrained, zinc deposit in Canada (please refer to the SEDAR-filed amended and restated technical report entitled “Mineral Resource Estimate for the Pine Point Lead-Zinc Project, Hay River, Northwest Territories, Canada” and dated January 25, 2019 for further information). The 2018-2019 drill holes, once fully assayed, will be incorporated into the database with the objective of issuing a new resource estimate in H2 2019.

The Bathurst Mining Camp, located in northern New Brunswick, has Indicated Mineral Resources of 1.96 Mt grading 5.77% zinc, 2.38% lead, 0.22% copper and 68.9 g/t silver (9.00% Zinc Equivalent (“ZnEq”)) and Inferred Mineral Resources of 3.85 Mt grading 5.34% zinc, 1.49% lead, 0.32% copper and 47.7 g/t silver (7.96% ZnEq) in the Key Anacon and Gilmour South deposits. The estimate used a Zn Equivalent (ZnEq) cut-off grade of 5.5%. Zinc equivalency percentages are calculated using metal prices, forecasted metal recoveries, and smelter payables (ZnEq=Zn%+0.661*Pb%+1.749*Cu%+0.018*Ag g/t) based on a revenue factor of 1.1 and the following metal prices: zinc at US$1.10/lb, lead at US$0.90/lb, copper at US$2.72/lb and silver at US$15.90/oz. The calculation includes estimated mining cost of USD$45/Tonne and estimated total operating cost of USD$70/Tonne. Estimated metal recoveries were of 84% Zinc, 60% Lead, 52% Copper and 65% Silver. (see technical report and the press release dated February 20, 2019 for additional details).

In Québec, the Company owns 42,000 hectares that cover 12 grass-root zinc targets that will be selectively advanced through exploration in 2019.

Mr. Robin Adair, P. Geo and Vice President Exploration of Osisko Metals, is the Qualified Person who has approved of the scientific and technical disclosure contained in this news release.

The Bathurst Mining (“BMC”) current mineral resource estimate titled “NI 43-101 Maiden Resource Estimate for the Bathurst Mining Camp Project ” (the “MRE”) is dated April 4, 2019 with an effective date of February 20, 2019 covers the Gilmour South Deposit, the Key Anacon Main Deposit and the Key Anacon Titan Deposit. The independent qualified person for the 2019 BMC MRE is Pierre Desautels, P. Geo, of AGP Mining Consultants Inc.

These mineral resource estimates in this news release are not mineral reserves as they do not have demonstrated economic viability. The quantity and grade of the Inferred and Indicated Mineral Resource estimates are conceptual in nature and are estimated based on limited geological evidence and sampling. Resources are presented as undiluted and in situ for a medium underground operation with three separate deposits feeding a single processing facility and are considered to have reasonable prospects for eventual economic extraction. The BMC MRE is reported using a ZnEq cut-off grade of 5.5%. Zinc equivalency percentages are calculated using metal prices, forecasted metal recoveries, and smelter payables.
