Canadian Malartic Complex (operated by Agnico Eagle Mines Limited)

Agnico Eagle Mines Limited (“Agnico”) continues to advance studies on optimizing its Abitibi platform, where the Canadian Malartic mill is expected to play a central processing role. Macassa’s AK deposit has now been incorporated into Agnico’s production guidance for 2024 to 2026. At Upper Beaver, Agnico is conducting a trade-off analysis comparing transporting and processing ore at its LaRonde mill to a standalone central mill for Upper Beaver and other satellite deposits. An exploration ramp and shaft are being considered at Upper Beaver in order to upgrade and further explore the deeper portions of the deposit. At Wasamac, Agnico is assessing hauling alternatives and the optimal mining rate for transporting and processing ore at the Canadian Malartic mill. Agnico expects to complete internal technical evaluations for both Upper Beaver and Wasamac, all as part of a group of studies on optimizing the company’s Abitibi platform, in the first half of 2024. In February, Agnico declared an initial Probable Mineral Reserves of 5.17 million ounces of gold (47.0 million tonnes grading 3.42 g/t gold) in the central portion of the East Gouldie deposit.

In addition to the 5% net smelter return (“NSR”) royalty on the Canadian Malartic Mine, Osisko also holds a 5% NSR royalty on the East Gouldie and Odyssey South deposits, a 3% NSR royalty on the Odyssey North deposit and a 3-5% NSR royalty on the East Malartic deposit, which are located adjacent to the Canadian Malartic Mine. Osisko also holds a C$0.40/tonne royalty on any ore sourced from outside the royalty boundaries processed through the Canadian Malartic mill, such as Wasamac. Osisko owns 2% NSR royalties that cover most of Agnico’s Kirkland Lake regional properties, including AK and Upper Beaver deposits.

CSA Mine (operated by Metals Acquisition Limited)

In late March 2024, Metals Acquisition Limited (“MTAL”) announced the filing of its 2023 annual report. MTAL replaced the second grinding mill and subsequently operated at target rates without issue and completed the ventilation and cooling upgrades for CSA. On the financial front, and subsequent to year-end 2023, MTAL successfully raised A$325 million through its listing on the Australian Stock Exchange. Proceeds from the ASX listing were used to repay in full the deferred consideration facility to Glencore in connection with MTAL’s acquisition of CSA, and the balance is expected to be used to: increase working capital to facilitate operational flexibility and potential production growth, and also to provide additional funding for exploration programs and mine development at the CSA mine.

Osisko owns a 100% silver stream on the CSA mine as well as a 3.0-4.875% copper stream having an economic effective date of June 15^th, 2024. Osisko also owns a minimum seven-year Right of First Refusal over future royalties / streams sold on any asset owned or purchased by MTAL.

Island Gold / Magino (operated by Alamos Gold Inc.)

In late March 2024, Alamos Gold Inc. (“Alamos”) announced the friendly acquisition of Argonaut Gold Inc. (“Argonaut Gold”) and its Magino gold mine and mill, located immediately adjacent to Alamos’ Island Gold mine. The transaction is expected to close in the third quarter of 2024. Alamos’ previously planned Phase 3+ mill expansion construction work at Island Gold will no longer be required following the announced acquisition of the 10,000 tonnes per day Magino mill, which is located two kilometres from the Island Gold shaft (currently under construction). The larger mill and tailings infrastructure at Magino will now also accommodate the rapidly growing Mineral Reserve and Resource base at Island Gold.

Alamos’ expanded and accelerated 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 1.38% NSR royalty. A small fraction of the eastern limit of the Magino pit is covered by a 3% NSR royalty, with GEOs earned to Osisko expected from 2030 onwards. The underground exploration potential previously highlighted by Argonaut Gold on this claim is located less than 300 metres from the existing Island Gold underground infrastructure.

Tocantinzinho (operated by G Mining Ventures Corp.)

In early April 2024, G Mining Ventures Corp. (“G Mining”) announced that construction of its flagship Tocantinzinho gold project (“TZ”) in Brazil remained on track with the first gold pour expected to occur during the second half of 2024, and with commercial production expected soon thereafter. Overall physical construction at TZ was approximately 83% complete as of February 29^th, 2024. Site infrastructure is substantially complete and the SAG and ball mill components installation is now underway. Mining and stockpiling of ore commenced in November 2023, and as of February 29^th, 2024, ore stockpiles at TZ totaled 0.8 million tonnes grading 0.8 grams/tonne gold.

Osisko owns a 0.75% NSR royalty on the Tocantinzinho project.

Namdini (operated by Cardinal Namdini Mining Limited)

Cardinal Namdini Mining Limited, a majority-owned subsidiary of Shandong Gold Mining Co. Ltd. (“Shandong”) has now officially started mining at the Namdini gold project in Ghana. In addition, the construction of the processing plant, the water abstraction and tailings storage facilities, the 161Kv power transmission line, the segment ponds and the road network, are all nearing completion. A 25-kilometre access road from the town Balungu to the mine site has been completed and is now open to the public, connecting over ten communities. As stated previously by Shandong, first gold at Namdini is expected to be poured in the fourth quarter of 2024.

Osisko owns a 1% NSR royalty covering the Namdini gold project.

Copperwood (operated by Highland Copper Company Inc.)

In March 2024, Highland Copper Company Inc. (“Highland”) announced that after a year-long review of the Copperwood copper-silver project, the Michigan Strategic Fund Board had unanimously approved a performance-based grant of US$50 million from the Strategic Site Readiness Program (“SSRP”). The SSRP program is funded through the Strategic Outreach and Attraction Reserve Fund and provides economic assistance for the purpose of creating investment-ready sites to attract and promote investment in the state. The grant funds will be in the form of performance-based reimbursements for eligible activities relating to infrastructure development, most notably expenditure on roads, communications infrastructure and bringing power to site. The transfer of funds to Highland is pending final approval from the Appropriations Committees in both the Michigan House and Senate.

Osisko currently owns a 1.5% NSR royalty on copper production, and an 11.5% NSR royalty on silver production at Copperwood. At Osisko’s election, the silver royalty percentage may be increased to 100% on Copperwood (and on Highland’s White Pine North project) for a payment of US$23 million.

Ermitaño (operated by First Majestic Silver Corp.)

In early April 2024, First Majestic Silver Corp. (“First Majestic”) released updated 2023 Mineral Reserve and Mineral Resource estimates for the Ermitaño underground mine at its Santa Elena Silver/Gold Mine in Sonora, Mexico. Santa Elena’s (Ermitaño’s) Proven & Probable Mineral Reserve estimates remained relatively unchanged despite record production of 9.6 million silver equivalent ounces at Ermitaño in 2023. In terms of catalysts over the next year, continued Resource expansion potential at the Ermitaño mine (Luna and Soledad Zones) remains a core focus for First Majestic, with 22,000 metres of drilling planned for 2024.

Osisko owns a 2% NSR royalty on the Ermitaño project and the Cumobabi property, including the Luna and Soledad Zones.

(1) Gold Equivalent Ounces

 GEOs are calculated on a quarterly basis and include royalties and streams. Silver earned from royalty and stream agreements are converted to gold equivalent ounces by multiplying the silver ounces earned by the average silver price for the period and dividing by the average gold price for the period. Diamonds, other metals and cash royalties are converted into gold equivalent ounces by dividing the associated revenue earned by the average gold price for the period.
