October 2, 2025 – TheNewswire - Vancouver, Canada – Radius Gold Inc. (TSXV: RDU) ("Radius" or the "Company") is pleased to announce that it has signed a Mining Assignment and Option Agreement to acquire the 1,800-hectare Hidekel concessions directly adjoining its 100%-owned Tierra Roja copper project in southern Peru (see press release Feb 28, 2025).

The signing of this Mining Assignment and Option Agreement consolidates Radius&s land position at Tierra Roja and strengthens the Company&s control over one of the most compelling copper exploration targets in the district.

Drill Permitting and Progress Update

Radius has advanced permitting and preparation for the first drill program at Tierra Roja. The Company has secured key approvals required to drill, including:

• Ficha Técnica Ambiental (FTA) authorizing drilling and construction of up to 20 drill platforms and access roads.

• Archaeological permit confirming clearance of cultural heritage impacts.

• Water supply contract with a licensed provider.

• Selected local drill contractor.

• Federal land-use certification confirming the project area is unoccupied government land.

An additional access waiver is required, which is in progress. Radius&s legal team has advised that the final authorization for initiation of activities is expected to be issued beginning of November.
