Corporate Updates

OSISKO PROVIDES SELECT ASSET UPDATES

Montréal, December 2nd, 2024 – Osisko Gold Royalties Ltd (the “Company” or “Osisko”) (OR: TSX & NYSE) is

pleased to provide some select asset updates. All monetary amounts included in this update are expressed in

Canadian dollars, unless otherwise noted.

Jason Attew, President & CEO of Osisko commented: “As we head into the final stretch of 2024, positive progress

continues to be made across Osisko’s high-quality asset base thanks to the ongoing hard work and dedication of

our operating partners. These achievements continue to surface incremental value for Osisko and its shareholders,

largely by underpinning the Company’s near -to-medium-term gold equivalent ounce delivery growth profile.

Osisko’s projected growth trajectory remains peer -leading and comes from assets that require no contingent

capital along the way; in other words, our five-year growth outlook is already entirely bought and paid for.”

SELECT ASSET UPDATES

Mantos Blancos (operated by Capstone Copper Corp.)

On October 31st, 2024, Capstone Copper Corp. (“ Capstone”) provided an update on its Mantos Blancos mine

located in the Antofagasta Region of Chile. In July 2024, a successful two-week planned shutdown was completed

which included the installation of a new holding tank and additional pumps in the tailings area. These investments

addressed the deficiencies identified that were preventing the sustained achievement of the 20,000 tonnes per

day (“ tpd”) throughput capacity from the plant’s sulphide concentrator. Following the plant ramp- up period in

August, Capstone reported that ore throughput averaged 18,062 tpd through to the end of the third quarter of

2024, with plant throughput meeting or exceeding the nameplate capacity of 20,000 tpd over 23 separate operating

days (as at September 30th, 2024). Capstone subsequently reported that the average daily throughput at Mantos

Blancos for October 2024 was 18,481 tpd and that from November 1 st to November 16th, 2024, plant throughput

averaged over and above 20,000 tpd. The overall variability of the milling process has been significantly reduced

and consistently higher throughput is expected throughout the fourth quarter of 2024, and beyond.

Additionally, Capstone continues to highlight the potential for a Phase II expansion at Mantos Blancos over the

next few years, with a Feasibility Study, looking at increasing throughput to at least 27,000 tpd, expected towards

the end of 2025.

Osisko, through its wholly-owned subsidiary Osisko Bermuda Limited (“Osisko Bermuda”), owns a silver stream

on Mantos Blancos. Under the stream agreement, Osisko Bermuda will purchase 100% of payable silver produced

at Mantos Blancos until 19.3 million ounces have been delivered and 40% of payable silver thereafter for the

remaining life-of-mine (“LOM”).

Island Gold District (operated by Alamos Gold Inc.)

On September 12th, 2024, Alamos Gold Inc. (“Alamos”) provided updated three -year production and operating

guidance incorporating the recently completed acquisition of the Magino mine and mill (“ Magino”), now part of

Alamos’ Island Gold District. Alamos is spending US$40 million to expand the newly acquired Magino mill to 12,400

tpd by 2026. This will accommodate ore from both Magino and the increased production from the Island Gold Mine

(“Island Gold”) following the completion of the Island Gold Phase 3+ Expansion in the first half of 2026. The Phase

3+ Expansion includes a new shaft which is expected to increase underground production from Island Gold to at

least 2,400 tpd. On November 4 th, 2024, Alamos announced that it expects to conclude an Island Gold District

LOM plan by mid-2025, followed by an Island Gold District Expansion Study by the fourth quarter of 2025.

Alamos is also now considering a further expansion of the Island Gold District in the future that would potentially

increase production from the underground operation, over and above the Phase 3+ Expansion already underway.

2

According to Alamos, a further expansion of the Magino mill to 15,000 to 20,000 tpd will be evaluated, including

possibly increasing underground throughput sourced from Island Gold beyond the currently planned 2,400 tpd.

Finally, the union of Island Gold and Magino will continue to facilitate previously impossible exploration initiatives,

whereby Alamos sees potential to expand the Magino open pit to the east, which was previously constrained by

the boundary between the two separately owned properties; drilling is already underway.

Osisko owns a 1.38- 3.0% net smelter return (“ NSR”) royalty on the Island Gold Mine. With the district now fully

consolidated, Alamos’ expanded and accelerated Phase 3+ Expansion mine plan at Island Gold is anticipated to

transition a greater proportion of production towards Osisko’s 2% and 3% NSR royalty boundaries earlier in the

mine plan, as opposed to the mineral inventory covered by Osisko’s current 1.38% NSR royalty. A small portion

of the eastern limit of the Magino pit is also covered by the 3.0% NSR royalty owned by Osisko.

Éléonore Mine (operated by Newmont Corp.)

On November 25th, 2024, Newmont Corp. (“Newmont”) announced that it has agreed to sell its Éléonore operation

in Northern Quebec, Canada, to Dhilmar Ltd (“Dhilmar”) for US$795 million in cash consideration. The transaction

is expected to close in the first quarter of 2025, subject to certain conditions being satisfied. Dhilmar is a newly

incorporated, UK -based private mining company. The company is led by its CEO and Managing Director,

Alexander Ramlie, and supported by board members with decades of mining experience across a range of

commodities and with both surface and underground operations. Mr. Ramlie and his team worked closely with

Newmont in 2016 to acquire the Batu Hijau copper -gold mine in Indonesia on behalf of PT Amman Mineral

Internasional Tbk.

Osisko has a 2.2 -3.5% NSR royalty on Éléonore, with a sliding scale based on production. The royalty starts at

2.0% for the first 3.0 million ounces of gold and increases by 0.25% per million ounces produced thereafter. If the

spot gold price exceeds US$500 per ounce, the rate is multiplied by 1.1. The maximum rate is capped at 3.5%.

As at October 31 st, 2024, Éléonore has produced over 2.46 million ounces of gold, resulting in a current NSR

royalty rate of 2.2%.

Seabee Mine (operated by SSR Mining Inc.)

On November 6th, 2024, SSR Mining Inc. (“SSR Mining”) announced that gold production from Seabee was 10,252

ounces in the third quarter of 2024, reflecting the temporary suspension of operations at Seabee due to forest

fires. Following the temporary suspension, employees were cleared to return to the site on September 23 rd, 2024

to begin repairs to ancillary equipment damaged by the fires, including power poles, piping, and exploration

equipment. Operations at Seabee were fully reinstated on October 11, 2024. As a result, full-year 2024 production

guidance for Seabee is now 65,000 to 70,000 ounces of gold (previously 75,000 to 85,000 ounces of gold).

Osisko owns a 3.0% NSR royalty on Seabee, including the Santoy, Porky, and Shane exploration targets.

Namdini Gold Mine (operated by Cardinal Namdini Mining Ltd., a majority-owned subsidiary of Shandong Gold

Mining Co Ltd.)

On November 8th, 2024, Cardinal Namdini Mining Ltd. (“ Cardinal Namdini”) hosted a commissioning ceremony

for the Namdini Gold Mine in Ghana. Cardinal Namdini reiterated that it is committed to becoming a leader in

sustainable mining. The event was honoured by the presence of the many esteemed guests including: H.E. Nana

Addo Dankwa Akufo- Addo, President of the Republic of Ghana; H.E. Tong Defa, Ambassador Extraordinary &

Plenipotentiary of the People’s Republic of China to Ghana ; Mr. Han Yaodong, CEO of Shandong Gold Group;

Kugbilsong Nanlebeglang, Paramount Chief of the Talensi Traditional Area; and, Hon. Samuel A. Jinapor, Ghana

Minister for Lands & Natural Resources. Subsequent to the commissioning update, news of first gold being poured

at Namdini was announced on November 11th, 2024.

Namdini has been developed as a single open-pit mine feeding a conventional carbon-in-leach processing facility,

with mining expected to initially focus on a high-grade starter pit area towards the north of the deposit.

Osisko owns a 1.0% NSR covering the Namdini Gold Mine.

Dalgaranga Project (operated by Spartan Resources Ltd.)

On November 25th, 2024, Spartan Resources Ltd. (”Spartan”) announced that it has received approvals from both

the Department of Energy, Mines, Industry Regulation and Safety and the Department of Water and Environment

Regulation for the mining and processing of underground ores at the Dalgaranga Gold Project (“ Dalgaranga”),

along with modifications to the mill. These approvals were an important step towards the restart of Spartan’s 100%-

owned Dalgaranga project following the receipt of all key regulatory approvals required to allow the mining and

processing of underground ores to proceed.

On November 27th, 2024, Spartan also announced that recent surface drilling has confirmed a significant new gold

discovery, named “Freak”, immediately south (110 meters) of the Pepper Gold Deposit at Dalgaranga. Highlight

intercepts included 5.37 grams per tonne (“g/t”) gold (“Au”) over 10.26 meters (”m”), and 5.30 g/t Au over 7.43 m,

amongst others. Follow-up wedge holes from the parent discovery hole have now returned multiple high- grade

intercepts in the new minerali zed position, which remains open down- plunge, sits in a similar orientation to the

Pepper and Never Never G old Deposits and exhibits identical alteration styles and mineralogy to the first two

breakthrough high-grade underground discoveries at Dalgaranga. This exciting new discovery, which is currently

the focus of an intensive three- to-four diamond rig drilling program, represents the third significant high- grade

discovery made by Spartan at Dalgaranga adjacent to the existing 2.5 million tonne per annum process plant and

supporting surface infrastructure.

On September 30 th, 2024, Osisko announced that it had entered into an agreement to acquire a 1.8% gross

revenue royalty (“GRR”) on Dalgaranga operated by Spartan in Western Australia. The consideration to be paid

by Osisko to the seller, Tembo Capital Mining Fund III, for the GRR will total US$44 million (“ the Transaction”).

Spartan has the ability to buy back up to 20% of the 1.8% GRR for a total of A$3.15 million until February 2027.

Closing of the Transaction is subject to approval from Australia’s Forei gn Investment Review Board which is

expected in the fourth quarter or 2024.

Hermosa Project (operated by South32 Ltd.)

In its September 2024 Quarterly Activities Report published on October 20 th, 2024, South32 Ltd. (“ South32”)

announced that it had invested US$124 million at Hermosa during the September 2024 quarter . South32

progressed construction of the Taylor zinc -lead-silver project (“Taylor”), as well as on an exploration decline for

the Clark battery-grade manganese deposit. All critical path dewatering wells were also commissioned during the

period.

Construction of Taylor continues to progress as planned. The headframe for the main shaft has been completed

and commissioning of the hoisting system for the ventilation shaft is underway. Shaft sinking is on track to

commence in the December 2024 quarter. South32 is expecting to spend US$530 million at Taylor in its fiscal

year 2025. Taylor has an initial 28- year LOM based on current Mineral Reserves, with the potential to realize

further exploration upside, and first production is still on schedule for South32’s fiscal year 2027.

Osisko owns a 1.0% NSR royalty on zinc and lead sulphide ores produced at Taylor / Hermosa.

Wharekirauponga Project (operated by OceanaGold Ltd.)

On October 6 th, 2024, OceanaGold Ltd. (“ OceanaGold”) announced that it welcomed the inclusion of its Waihi

North Project, which includes the Wharekirauponga (“WKP”) proposed underground mine, in the list of proposed

projects under the New Zealand Government's Fast -track Approvals Bill for regionally and nationally significant

infrastructure and development projects. The Fast-track Approvals Bill is expected to be passed into law later this

year, allowing listed projects to apply directly to a government-appointed expert panel for a final decision.

On November 14 th, OceanaGold also reported exploration results from drilling at WKP, located ~10 km from its

operating Waihi gold mine, where highlights included 34.7 g/t Au over 4.2 m (true width), 16.8 g/t Au over 5.7 m,

and 13.0 g/t Au over 6.6 m. In addition, OceanaGold noted that it is planning to release a Pre-Feasibility Study for
