OSISKO PUBLISHES INAUGURAL ASSET HANDBOOK AND 2021 ESG REPORT

Montréal, April 19th, 2022 – Osisko Gold Royalties Ltd (the “ Corporation” or “Osisko ”) (OR: TSX & NYSE) is

pleased to announce the publication of its inaugural Asset Handbook and the second edition of the Corporation’s

environmental, social and governance (“ESG”) report, Growing Responsibly.

2022 Asset Handbook

Osisko has built a deep portfolio of high-quality royalty and streaming assets, in favourable jurisdictions, operated

by reputable mining partners . The portfolio provides exposure to over 165 royalties and streams , including

20 producing assets which underpin Osisko’s 2022 guidance of 90,000 to 95,000 gold equivalent ounces (“GEOs”)

at a 93% cash margin 1. To this solid foundation, significant internal growth is expected over the coming years ,

demonstrated by the recently announced five-year outlook which reaches 130,000 to 140,000 GEOs in 2026.

Osisko’s mining partners continue to add value through exploration, with an average of over 1 million meters drilled

each of the past five years on shared assets, unlocking significant upside through new discoveries, reserve and

resource additions and mine extensions and expansions. Over the course of 2021, Osisko’s estimate of

Attributable GEOs2 (net of depletion) grew across all categories , experiencing an increase of 6% in Proven and

Probable reserves, 12% in Measured and Indicated resources and 4% in Inferred resources.

Sandeep Singh, President and CEO of Osisko commented: “The 2022 Asset Handbook provides a comprehensive

review of our unique asset base and the significant upcoming catalysts supporting both near -term and long-term

growth. In our view, long-term value is only preserved and created for as long as Osisko and its partners operate

in a responsible manner. Through our second edition of Growing Responsibly , we seek to provide a holistic

summary of our ESG footprint, our continued ambition to improve, and our achievements against that ambition

throughout the year. The company is going through a transformational phase, and we trust that these reports will

assist stakeholders in understanding the fundamental value, and sustainable nature, of our business.”

2021 ESG Report

In 2021, Osisko advanced its management of ESG matters with notable achievements across all areas. The

following are select highlights of Osisko’s commitment to growing sustainably:

• Launched inaugural ESG report, Growing Responsibly , to better communicate the Corporation’s

performance and approach to managing ESG matters;

• Committed to the UN Global Compact to formally align with its Ten Principles;

• Formed a strategic partnership with Carbon Streaming Corporation to promote global decarbonisation

and biodiversity efforts through carbon credit streaming transactions;

1 Cash margin is a non-IFRS financial performance measure which has no standard definition under IFRS. It is calculated by deducting the cost of

sales from the revenues (excluding depletion). For more details, refer to Osisko’s press release dated February 24, 2022 entitled “Osisko Reports

Strong 2021 Results and Provides 2022 Guidance and 5 -Year Outlook” filed on Sedar (www.sedar.com) and available on Osisko’s website

(www.osiskogr.com).

2 For the purpose of estimating Attributable GEOs, royalty assets are tabulated using the percentage of revenues or metal produced that is attributable

to Osisko. In the case of a stream, we adjust the percentage of metal attributable to Osisko for the ongoing transfer price payable by Osisko so the

resulting total can be considered on a 100% attributable basis. For a detailed breakdown of the mineral resources and reserves, and the attributable

royalty or stream on individual assets, please refer to the Asset Handbook on Osisko’s website at www.osiskogr.com . Estimates of Attributable

GEOs are subject to uncertainty due to a number of factors that are described in the Cautionary Notes section of Asset Handbook available on

Osisko’s website.

• Engaged a third party expert to provide an initial estimate of Scope 3 GHG emissions intensity

attributable to Osisko’s share of the revenue from its portfolio;

• Enhanced reporting by aligning Osisko’s disclosure with Sustainability Account Standards Board (“SASB”)

industry standards; and

• Maintained a leading position within MSCI’s ESG rating and improved Osisko’s position in Sustainalytics

precious metals ESG ranking.
