Osisko Metals Announces Closing of Fully-Subscribed $10 Million Private Placement of Flow-Through Shares

MONTRÉAL, July 16, 2019 - Osisko Metals Inc. (the "Corporation" or "Osisko Metals") (TSX-V: OM; FRANKFURT: 0B51; OTCQX: OMZNF) is pleased to announce that it has closed its previously-announced "best efforts" brokered private placement, pursuant to which the Corporation sold an aggregate of 13,553,114 common shares of the Corporation that will qualify as "flow-through shares" (within the meaning of subsection 66 (15) of the Income Tax Act (Canada)) ("Flow-Through Shares") for aggregate gross proceeds of approximately $10 million (the "Offering"). Under the Offering, 6,410,257 Flow-Through Shares were issued at a price of $0.78 per Flow-Through Share for gross proceeds of approximately $5 million and 7,142,857 Flow-Through Shares were issued at a price of $0.70 per Flow-Through Share for gross proceeds of approximately $5 million.

The Offering was led by Canaccord Genuity Corp. on behalf of a syndicate of agents that included Haywood Securities Inc. (together, the "Agents"). In consideration for their services, the Corporation paid the Agents a cash commission equal to 5.0% of the gross proceeds of the Offering, provided, however, that no cash commission was paid to the Agents on proceeds from any Flow-Through Shares purchased by certain persons on the "President's List".

The following "insiders" of the Corporation have subscribed for Flow-Through Shares under the Offering:

Note: (1) Cathy Singer Professional Corp., a holding company of Ms. Cathy Singer, subscribed under the Offering.

Each subscription by an "insider" is considered to be a "related party transaction" for purposes of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions ("MI 61-101") and Policy 5.9 – Protection of Minority Security Holders in Special Transactions of the TSX Venture Exchange. Pursuant to MI 61-101, the Corporation has filed a material change report providing disclosure in relation to each "related party transaction" on SEDAR under Osisko Metals' issuer profile at www.sedar.com. The Corporation did not file the material change report more than 21 days before the expected closing date of the Offering as the details of the Offering and the participation therein by each "related party" of the Corporation were not settled until shortly prior to the closing of the Offering, and the Corporation wished to close the Offering on an expedited basis for sound business reasons. The Corporation is relying on exemptions from the formal valuation and minority shareholder approval requirements available under MI 61-101. The Corporation is exempt from the formal valuation requirement in section 5.4 of MI 61-101 in reliance on sections 5.5(a) and (b) of MI 61-101 as the fair market value of the transaction, insofar as it involves interested parties, is not more than the 25% of the Corporation's market capitalization, and no securities of the Corporation are listed or quoted for trading on prescribed stock exchanges or stock markets. Additionally, the Corporation is exempt from minority shareholder approval requirement in section 5.6 of MI 61-101 in reliance on section 5.7(b) as the fair market value of the transaction, insofar as it involves interested parties, is not more than the 25% of the Corporation's market capitalization.

The gross proceeds from the Offering will be used by the Corporation to incur eligible "Canadian exploration expenses" that will qualify as "flow‐through mining expenditures" as such terms are defined in the Income Tax Act (Canada) (the "Qualifying Expenditures") related to the Corporation's projects in Canada. All Qualifying Expenditures will be renounced in favour of the subscribers of the Flow‐Through Shares effective December 31, 2019.

All securities issued under the Offering are subject to a four month hold period which will expire November 17, 2019. The Offering is subject to final acceptance of the TSX Venture Exchange. The securities offered have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements. This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any State in which such offer, solicitation or sale would be unlawful.
