GOLD ROYALTY TO ACQUIRE PRODUCING PEDRA BRANCA GOLD AND COPPER ROYALTY

VANCOUVER, BC, Dec. 8, 2025 /PRNewswire/ - Gold Royalty Corp. ("Gold Royalty" or the "Company") (NYSE American: GROY) is pleased to announce that it has entered into an agreement to acquire an existing royalty (the "Royalty") on the Pedra Branca mine, from BlackRock World Mining Trust plc ("BlackRock") for $70 million in cash (the "Transaction"). Pedra Branca is an operating copper and gold mine located in Brazil and currently owned and operated by a subsidiary of BHP Group Limited ("BHP"). In August 2025, BHP announced the sale of the Pedra Branca mine and other assets in the Carajás region to CoreX Holding BV, which is expected to complete upon the satisfaction of customary closing conditions. All amounts are expressed in U.S. dollars unless otherwise noted.

David Garofalo, Chairman and CEO of Gold Royalty, commented: "We are pleased to announce another significant addition to our portfolio. The acquisition of the Pedra Branca royalty represents an immediate and material addition to our cash flows. On completion, our portfolio of high-quality assets will include eight cash flowing assets and a deep pipeline of over 250 royalty and streaming interests."

Transaction Highlights:

• Materially accretive to Gold Royalty cash flows: For the 12 months ended June 30, 2025, the Royalty expense recorded to the prior royalty holder was approximately $7.9 million, equivalent to approximately 2,800 gold equivalent ounces ("GEOs")* at an average gold price of $2,811 per ounce. The Royalty is expected to add significant and meaningful cash flow to Gold Royalty after completion of the acquisition, including as a result of the current gold pricing climate.
• Enhances leverage to gold and copper: The Royalty's terms include a 25% net smelter return royalty ("NSR") on gold and 2% NSR on copper produced from Pedra Branca. This further enhances Gold Royalty's already strong gold exposure from both a revenue and asset value perspective. Gold Royalty believes the enhanced copper exposure is timely, given the currently strong long-term fundamentals for the metal based on demand projections to support the coming global transition to renewable energy.
• Attractive royalty structure: The Royalty has full coverage over the Pedra Branca East and Pedra Branca West deposits. The Royalty does not include any step-down options so it provides full exposure to longer term optionality of the asset.
• Exposure to top quality asset: The Pedra Branca East underground copper and gold mine achieved first production in 2020 and had an approximate 800 ktpa mining rate operated by OZ Minerals. BHP acquired Pedra Branca when it acquired OZ Minerals in 2023 and has continued to extend the mine life and reported increases in Pedra Branca's Mineral Resources and Ore Reserves, as reported in the BHP Annual Report for the year ended June 2025.
• World-class operators: The mine was constructed by OZ Minerals and is currently operated by BHP. On August 18, 2025, BHP announced that a wholly-owned subsidiary of CoreX Holding BV had agreed to acquire Pedra Branca, along with BHP's other Carajás copper assets in Brazil.
• Top-tier jurisdiction: Pedra Branca is located in the Carajás region in Brazil's Pará state, a prolific mining region which is home to world-class iron ore deposits as well as copper, gold, manganese, copper, tin, and aluminum.

The Pedra Branca mine is located in Água Azul do Norte, which is approximately 160 km from Marabá and 900 km from Belém in the state of Pará, Brazil. Electricity is supplied to the mine via a 5 MW transmission line.

The plant has been operating and depositing tailings into a nearby exhausted open pit.

The mine consists of an iron oxide copper gold deposit. High-grade zones of semi-massive and breccia mineralization with dominant chalcopyrite as the key copper-bearing mineral.

Pedra Branca was acquired by OZ Minerals in 2018 when OZ Minerals purchased Avanco Resources including its projects in the Carajás Copper Region and the Gurupi Greenstone Belt.
