Radius Gold executes formal Option Agreement for 100% of the Jonco Silver Project, Peru

Vancouver, British Columbia - Radius Gold Inc. (TSX-V: RDU) ("Radius" or the "Company") is pleased to announce that it has executed a formal Option Agreement (the "Agreement") with Minera Joncijirca S.A.C. for the Jonco Silver Project (the "Project") in central Peru.

As previously announced on February 27, 2026, the binding Letter of Intent has now been formalized into a definitive agreement. The Agreement grants Radius (through its subsidiary, Minera Aymara S.A.C.) an exclusive option to acquire 100% of the seven mining concessions comprising the Jonco Silver Project.

Transaction Terms (as previously disclosed and now formalized)

Under the Agreement, Radius may earn a 100% interest in the Project over a five-year period commencing on the receipt of permits to drill the Project through:

• Staged cash payments totaling US$4.15 million.
• US$7.0 million in exploration expenditures.
• Issuance of 250,000 Radius common shares on a staged schedule.

Upon exercise of the option and acquisition of 100% ownership, the vendor will retain a 2% NSR royalty, reducible by 0.5% for a one-time US$1.0 million payment. The Project is also subject to an existing 1.25% NSR royalty held by Compañía de Minas Buenaventura S.A.A. on two concessions.

The TSX Venture Exchange has accepted the Agreement and Radius has issued the initial 50,000 common shares to the vendor. The shares have a regulatory-prescribed resale restriction until November 10, 2026. The Company will also make the initial US$50,000 cash payment to the property vendor.

About the Jonco Silver Project

The Project hosts a large-scale polymetallic silver-gold-lead-zinc system associated with dacite flow domes and diatreme breccias. It covers 3,830 hectares with multiple drill and geophysical targets, 11 historic drill holes (3,195m), and significant potential for bulk-tonnage mineralization. Additional details, including historical drill results and geological highlights, are set out in the Company's February 27, 2026 news release and on the Radius website.

"Execution of this Agreement is an important milestone for Radius as we secure formal access to the Jonco Silver Project," commented Luke Longridge, President of Radius Gold. "We are now positioned to advance surface exploration and target refinement, and I look forward to working with our team and other stakeholders as we progress through the permitting process."
