EXPLORATION UPDATE: RADIUS ADVANCES TIERRA ROJA PERMITS AND REVIEWS PROJECT PORTFOLIO

Radius Gold Inc. has provided an update on its exploration activities and project portfolio in Peru, Mexico and Guatemala.

Tierra Roja copper project -- Peru

Radius continues to advance permitting activities at the Tierra Roja copper project in southern Peru. The technical review for access has been approved by the regional government of Arequipa (GREM), representing a key milestone in the permitting process.

Project documentation is currently being processed by the Superintendencia de Bienes Nacionales (SBN) for evaluation of surface rights and issuance of a temporary surface-use permit. Upon completion, Radius expects to have all required approvals in place, including access authorization, ficha tecnica ambiental (FTA), archeological clearance and drill contracts, enabling application to GREM for the authorization to commence activities.

The exploration team has completed logistical and technical preparations, with multiple drill targets defined for testing once permits are granted. The appointment of Alejandro Ly as vice-president, exploration, in November, 2025, based in Lima, has significantly advanced the permitting process and project readiness.

Mr. Ly, vice-president, exploration, commented: "The progress achieved at Tierra Roja over recent months reflects a focused effort to advance permitting and prepare for drilling. With key approvals nearing completion, we believe the project is well positioned for the next phase of exploration."

Amalia gold-silver project -- Chihuahua, Mexico

Between 2019 and 2022, Radius and joint venture partner Pan American Silver Corp. completed 67 drill holes for 23,058 metres of diamond drilling at the Amalia project, defining high-grade gold-silver mineralization at the Amalia and El Cuervo zones.

Further significant drill interceptions were reported in the last drill holes (for example, Aug. 30, 2022, AMDD-066, 13.55 metres at 841 grams per tonne silver and 10.25 grams per tonne gold) and remain open to expansion along strike and downdip. Along the six-kilometre strike of the system, multiple targets remain untested.

Pan American held the right to earn a 65-per-cent interest under an existing option agreement. As operator, Pan American Silver suspended work on the property during merger negotiations with Yamana in 2022. Radius continues discussions with Pan American with the objective of agreeing on a pathway forward for the Amalia gold-silver project that appropriately reflects the value of the Amalia asset to Radius's shareholders.

Holly gold-silver project -- Guatemala

In Guatemala, regional mining activity continues to advance, providing a positive backdrop for the Holly gold-silver project. Radius holds a 40-per-cent interest in the Holly project through a joint venture with Volcanic Gold Mines Inc. The project hosts a high-grade epithermal gold-silver system with multiple vein structures. Holly's Pena vein hosts inferred resources of 1.32 million tonnes at 6.46 grams per tonne gold and 256 grams per tonne silver. The effective date of the mineral resource estimate is June 7, 2022, and a technical report on the Holly property is filed on the company's website and SEDAR+.

The commencement of construction works at Aura Minerals' Era Dorada underground mine, 40 kilometres south of Holly, highlights renewed development momentum within the district. The Era Dorada gold deposit hosts over three million ounces in measured and indicated (M&I) resources.

Regional portfolio activity and strategic positioning

Radius continues to evaluate new gold, silver and copper opportunities in Mexico, Peru and Chile. Two projects are currently in advanced stages of technical review and commercial due diligence.
