March 18, 2026 TheNewswire - Vancouver, British Columbia Radius Gold Inc. (TSXV: RDU,OTC:RDUFF) ("Radius" or the "Company") reports continued permitting progress and expanded geochemical definition of copper and silver mineralization at its Tierra Roja copper project located in the district of Atico, Province of Caravelí, Arequipa, southern Peru.
Permitting Updates
The Company has received provisional authorization for surface lands from the Superintendencia Nacional de Bienes Estatales (SBN) as part of the ongoing administrative process to establish the temporary surface access required for exploration activities.
Radius has also submitted the application for Authorization to Initiate Exploration Activities to the Gerencia Regional de Energía y Minas (GREM) of Arequipa, representing the final administrative step in the permitting sequence prior to commencement of the planned initial drill program.
Expansion of Surface Mineralization Footprint
The updated project map shown below integrates results from previous sampling campaigns together with 15 recent reconnaissance rock samples collected during the latest field campaign. The results confirm continued anomalous copper and silver values and extend the geochemical footprint of mineralization beneath partial caliche cover.
Copper and silver mineralization is associated with oxidized expressions developed over volcanic and sedimentary host rocks. The distribution of anomalous copper and silver values, together with geological mapping and geophysical surveys, supports the Company's interpretation of a concealed mineralized system partially masked by caliche cover.
Proposed drill targets have been designed to test covered areas within the northern portion of the project where geochemical, geophysical and geological indicators suggest the continuation of mineralization at depth.

Based on the current distribution of anomalous surface samples and geological interpretation, the Company considers the principal target corridor to extend for approximately 750 metres in strike length and up to 450 metres in width beneath partial caliche cover.
Alejandro Ly, Vice President Exploration of Radius, stated:
"Permitting at Tierra Roja continues to advance and recent surface sampling confirms that copper mineralization extends beneath caliche cover, expanding the footprint of the system. Our geological, technical and permitting work are progressing in parallel as we continue improving our understanding of the controls on mineralization and preparing the project for its planned initial drill program."
Sampling, Analytical Procedures and QA/QC
Surface sampling at Tierra Roja includes rock samples, trench samples and samples collected from shallow excavations during multiple reconnaissance campaigns completed by previous operators and by Radius. Radius has reviewed the available historical surface sampling database and has undertaken confirmation sampling that is consistent with the copper and silver geochemical anomalies identified to date on the project. Samples collected by Radius were analyzed by independent laboratories using established analytical and QA/QC procedures. As exploration advances, Radius will continue to apply industry-standard sampling and analytical protocols and follow recognized QA/QC practices in accordance with applicable regulatory requirements.
