Osisko Metals Intersects 18.50% Zinc+Lead Over 10.00 Metres at Pine Point

MONTREAL, May 16, 2019 - Osisko Metals Inc. (the “Company” or “Osisko Metals”) (TSX-V: OM; FRANKFURT: OB51; OTCQX: OMZNF) is pleased to announce additional assay results from 53 drill holes completed in the L-27, L-30 and N-32EXT areas within the East Mill Zone in the Pine Point Mining Camp (“PPMC”). Highlights include drill hole EM-18-PP-403 that intersected 14.66% zinc and 3.84% lead over 10.00 metres and hole EM-18-PP-291 that intersected 8.59% zinc and 2.38% lead over 3.25 metres. (See EMZ L27 map)

All intersections are within flat-lying tabular-style deposits, and are located between 8 to 33 metres vertical depths. Drill hole composites and location details are provided in Tables 1 & 2.

The objective of the 2018 – 2019 drill program was to convert the ComInco Ltd. unclassified near-surface historical resources into current mineral resources and to locally extend known zones of mineralization. An initial 2018 Inferred Mineral Resource of 38.4 Mt grading 4.58% zinc and 1.85% lead was calculated on historical drilling using the initial 317 drill holes out of a total of 1031 holes that were drilled by Osisko Metals during the 2018 and 2019 campaign. These latest East Mill Zone drill holes were not included in this 2018 Inferred Mineral Resource Estimate.

The East Mill Zone extends for 7.6 kilometres along strike, contains eight deposits, three of which were mined by Cominco, and are located 1.7 kilometres to the east of the existing electrical sub-station and former mill site along a main haulage road. Cominco produced 3,417,550 tonnes of 3.4% Zinc and 1.0% Lead from the L-37 pit, 262,170 tonnes of 2.8% Zinc and 1.1% Lead from the L-30 pit and 350,870 tonnes of 5.5% Zinc and 2.2% Lead from the underground M-40 mine. Reported NI43-101 Inferred Mineral Resources for the East Mill Zone total 5.50 million tonnes of 3.76% Zinc and 1.30% Lead.

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 (“PPMC”), located on the south shore of Great Slave Lake in the Northwest Territories, near established infrastructure, paved highway access and with 100 kilometres of mine haulage roads and power substation already in place. The PPMC currently hosts a NI43-101 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 Technical Report 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. PPMC is located on the south shore of Great Slave Lake in the Northwest Territories, near infrastructure and paved highway access and with 100 kilometres of haulage roads already in place. The Bathurst Mining Camp (“BMC”), located in northern New Brunswick, with NI43-101 Indicated Mineral Resources of 1.96 Mt grading 5.77% zinc, 2.38% lead, 0.22% copper and 68.9g/t silver (9.00% 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. In Québec, the Company owns 42,000 hectares that cover 12 grass-root zinc targets that will be selectively advanced through exploration in 2019.

Quality Assurance / Quality Control

Osisko Metals adheres to a strict Quality Assurance and Quality Control program with regard to core handling, sampling, transportation of samples and lab analyses. Drill core samples from the Pine Point project area were securely transported to its core facility in Hay River, Northwest Territories where they were logged and sampled. Samples selected for assay were shipped via secure transportation to the ALS Canada Ltd.’s preparation facility in Yellowknife. Pulps were analyzed at the ALS Canada Ltd. facility in North Vancouver, British Columbia. All samples are analyzed by four acid digestion followed by both ICP-AES and ICP-MS for ultra-trace level detection for a multi-element suite with a 1% upper detection limit for base metals. Samples reporting over 1% for Zn and 1% for Pb are analyzed by assay grade four acid digestion and ICP-AES analysis with an upper detection limit of 30% and 20% respectively. Samples reporting Zn >30% and or Pb >20% are analyzed by traditional titration.
