Helius Minerals Advances Progress on Serra Pelada Gold-PGM Project in Brazil

Helius Minerals has advanced negotiations with Brazilian governmental agencies and legal proceedings to finalize the Serra Pelada gold-PGM project acquisition. The company has also obtained historical technical, legal, and financial documentation, and is reviewing it to shape a clear strategy for re-permitting and redevelopment of the project. Helius has a twelve-month exclusivity period to ensure compliance with mining laws, address outstanding debts, and develop a detailed plan to rehabilitate the project.

VANCOUVER, BC, Aug. 11, 2025 — Helius Minerals Limited ("Helius" or the "Company") has made significant progress in advancing the acquisition of the Serra Pelada gold-PGM project in Brazil. The company has successfully negotiated with Brazilian governmental agencies and legal proceedings, bringing the project closer to finalization.

Helius signed a definitive exclusivity, share option, and acquisition agreement with Colossus Minerals Inc. in March 2025. Since then, the company has held several meetings with the Brazilian Ministry of Mines (MME) and the National Mining Agency (ANM), strengthening the strategic framework for the project's return to commercial production. Additionally, Helius has obtained access to a comprehensive collection of historical technical, legal, and financial documentation related to the project, which has been instrumental in shaping a clear strategy for re-permitting and redevelopment.

The twelve-month exclusivity period granted under the definitive agreement allows Helius to review and develop a plan to ensure compliance with relevant mining laws and regulatory requirements, formulate a comprehensive strategy to address outstanding debts of the Brazilian subsidiaries of Colossus, and develop a detailed plan to rehabilitate the Serra Pelada Project and its Brazilian subsidiaries.

The Serra Pelada Project was placed on a care and maintenance program in 2014 following Colossus' insolvency. The project has seen significant investment, including drilling and underground development. Given current metal prices, Helius believes it is an opportune time to evaluate alternative mining scenarios that could better unlock the full potential of this unique deposit.

Helius is working closely with legacy shareholders and the Cooperativa de Mineração dos Garimpeiros de Serra Pelada (COOMIGASP) to move the project forward efficiently. The company is also reviewing legacy debt and creditor arrangements associated with the project to support a sustainable path to redevelopment.

Helius Minerals is a mineral exploration company focused on identifying and exploring high-quality mineral assets across the Americas, with an emphasis on South American jurisdictions.
