About São Jorge

The São Jorge Gold Project is located in the Tapajós gold district in Pará State, Brazil, adjacent to regional highway BR-163. It is a granite-hosted, intrusion-related gold mineral system that is similar in style to the Tocantinzinho gold mine, located approximately 80 km to the northwest, which commenced commercial production in 2024 and produced 171,871 ounces of gold in 2025. Operational results at the Tocantinzinho gold mine are not necessarily indicative of mineralization at São Jorge.

On June 11, 2026, the Company announced a PEA for São Jorge that envisaged a conventional open-pit operation and gravity/leach circuit processing 5,500 tonnes per day ("tpd") (1.9 million tonnes per annum ("Mtpa")) over a 10.6-year mine life. The PEA modelled a base case after-tax net present value at a 5% discount rate ("NPV_5%") of US$532 million and an after-tax internal rate of return ("IRR") of 42.4%, utilizing a base case gold price of US$3,500 per ounce ("oz"), supported by a stable production profile averaging 51,250 oz of gold annually.

The PEA is preliminary in nature and includes inferred mineral resources, which are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the PEA, including the conceptual economics set out therein, will be realized.

Further information about the PEA referenced in this news release, including information in respect of data verification, key assumptions, parameters, risks and other factors, can be found in the technical report titled "NI 43-101 Technical Report and Preliminary Economic Assessment, São Jorge Project, Pará State, Brazil" with an effective date of June 9, 2026 (the "Technical Report"), which is available under the Company's profile on SEDAR+ at www.sedarplus.ca.
