CONSTRUCTION OF CANADIAN MALARTIC UNDERGROUND APPROVED,

INCREASING LIFE OF MINE GOLD PRODUCTION BY ~6.9 MILLION OUNCES

Montreal, February 16, 2021 - Osisko Gold Royalties Ltd ( “Osisko” or the “Corporation”) (OR: TSX &

NYSE) is pleased to announce that the Canadian Malartic Partnership ( the “Partnership”), comprising

Agnico Eagle Mines Limited (“Agnico”) and Yamana Gold Inc. (“Yamana”), have approved construction of

the Odyssey underground project (“Odyssey”) at the Canadian Malartic mine (“Canadian Malartic”).

- Royalty payments from underground production at Canadian Malartic beginning in 2023

- Average underground production of 545 koz of gold per annum from 2029 onwards (see Chart 1),

higher than previous Partnership disclosure of 400-450 koz gold per annum

- Osisko has a 3-5% net smelter return (“NSR”) royalty on the mineralization contained in the

underground mine plan

- Importantly, the majority of production is expected from deposits within Osisko’s 5% NSR royalty

boundary

- Mine life extended from 2028 to at least 2039 based on ~50% of current resources in mine plan

- US$30 million of drilling and exploration work planned in 2021 by the Partnership

- East Gouldie remains open with eleven drill rigs focused on definition and extension drilling

- Osisko also holds a C$0.40/tonne processing royalty on any ore from outside its royalty boundaries

processed through the Canadian Malartic mill, potentially adding further regional exploration upside

- Additional positive advancements announced by Agnico on the Upper Beaver and Hammond Reef

gold projects where Osisko holds a 2% NSR royalty

For more detail s, please refer to the press releases issued by each of Agnico and Yamana on

February 11, 2021 available on their respective websites.

Sandeep Singh, President and CEO of Osisko commented, “The construction decision for t he Odyssey

underground project by Agnico and Yamana secures the Canadian Malartic mine as Osisko’s flagship asset

for decades. It is difficult to over emphasize the importance of this catalyst for Osisko as Canadian Malartic

will continue to provide sustainable production until at least 2039 , with significant upside beyond . We

commend the Partnership for the exploration and engineering efforts that have led to this announcement.”

The Odyssey project hosts three mai n underground-mineralized zones: East Gouldie, East Malartic, and

Odyssey, the latter of which is sub -divided into the Odyssey North, Odyssey South and Odyssey Internal

zones. Osisko holds a 5% NSR royalty on East Gouldie, Odyssey South and the western half of East Malartic

and a 3% NSR royalty on Odyssey North and the eastern half of East Malartic.

The East Gouldie deposit makes up 70% of the planned underground mining inventory . The Odyssey

production forecast only considers about half of the total underground resources comprising inferred

resources of 13.58 million ounces (177.5 million tonnes of 2. 38g/t gold), as well as indicated resources of

0.86 million ounces (13.3 million tonnes of 2.01g/t gold) using a gold price assumption of US$1,250 per

ounce.

Exploration drilling at East Gouldie in 2020 totaled 97,000 meters and increased the inferred mineral resource

of the East Gouldie zone by 134% . The total exploration budget for 2021 has increased to 173,400 meters

(US$30 million) focusing on further infill and expansion of East Gouldie and regional targets. East Gouldie

alone will benefit from 141,400 metres of drilling which is ~80% of the total that has been drilled on East

Gouldie to date.

An NI 43 -101 Preliminary Economic Assessment technical report for the Canadian Malartic operation is

expected to be filed by the Partnership in March 2021 and will include a summary of the Odyssey

underground project. More detail s can be found in the Agnico and Yamana press releases dated

February 11, 2021 titled “Agnico Eagle Reports Fourth Quarter and Full Year 2020 Results” and “Yamana

Gold Reports Strong Fourth Quarter and Full Year 2020 Results”, respectively.

Upper Beaver and Hammond Reef Updates

Agnico also provided an update on potential growth opportunities beyond 2024, highlighting two projects on

which Osisko has a 2% NSR royalty – the Upper Beaver project in Kirkland Lake Ontario and the Hammond

Reef project in Northwestern Ontario.

As of December 31, 2020, Upper Beaver has approximately 1.4 million ounces of gold and 20,000 tonnes of

copper in underground probable mineral reserves (8.0 million tonnes grading 5.43 g/t gold and 0.25%

copper); Agnico Eagle’s Kirkland Lake property al so hosts the Upper Canada, AK and Anoki -McBean

deposits; which together with Upper Beaver host an additional indicated resource of 1.71 million ounces

(17.2 million tonnes of 3.09g/t gold) and inferred resources of 4.07 million ounces (32.2 million tonnes of

3.93g/t).

In 2021, Agnico plans to drill 36,500 meters at Upper Beaver including additional shallow drilling to test an

open pit concept and further deep drilling to convert mineral resources to mineral reserves. An internal

technical study at Upper Beaver, incorporating drill results from 2020 and 2021, is expected to be completed

by the end of 2021.

At Hammond Reef , an internal technical study was completed by Agnico in 2020, which resulted in the

declaration of Agnico Eagle’s first mineral reserves for the project. Open pit mineral reserves are estimated

at 3.32 million ounces of gold (123.5 million tonnes grading 0.84 g/t gold). In addition, the project contains

2.3 million ounces of measured and indicated mineral resources (133.4 million tonnes grading 0.54 g/t gold).

The internal s tudy results showed average annual gold production of approximately 272,000 ounces at

average total cash costs of US$748 per ounce and average AISC of US$806 per ounce. Using a gold price

of US$1,550 per ounce, and a C$/US$ foreign exchange rate assumption of 1.30, the Hammond Reef project

has an after-tax IRR of 9.8% and an after-tax NPV (at a 5% discount rate) of approximately $245 million USD.

Agnico will continue to evaluate optimization of the project and potential mining scenarios to further improve

project economics.

geologically to have economic considerations applied to them that would enable them to be categorized as

mineral reserves and there is no certainty that the forecast production amounts will be realized.
