Radius Advances Permitting and Defines an Expanded Copper Mineralization Footprint at Tierra Roja Project, Peru

(TheNewswire)

March 18, 2026 – TheNewswire - Vancouver, British Columbia – Radius Gold Inc. (TSXV: RDU)(“Radius” or the “Company”) reports continued permittingprogress and expanded geochemical definition of copper and silvermineralization at its Tierra Roja copper project located in thedistrict of Atico, Province of Caravelí, Arequipa, southernPeru.

Permitting Updates

The Company has received provisional authorization forsurface lands from the Superintendencia Nacional de Bienes Estatales(SBN) as part of the ongoing administrative process to establish thetemporary surface access required for exploration activities.

Radius has also submitted the application forAuthorization to Initiate Exploration Activities to the GerenciaRegional de Energía y Minas (GREM) of Arequipa, representing thefinal administrative step in the permitting sequence prior tocommencement of the planned initial drill program.

Expansion of Surface MineralizationFootprint

The updated project map shown below integratesresults from previous sampling campaignstogether with 15 recent reconnaissance rock samples collected duringthe latest field campaign. The results confirm continued anomalouscopper and silver values and extend the geochemical footprint ofmineralization beneath partial caliche cover.

Copper and silver mineralization is associated withoxidized expressions developed over volcanic and sedimentary hostrocks. The distribution of anomalous copper andsilver values, together with geological mapping and geophysicalsurveys, supports the Company’s interpretation of a concealedmineralized system partially masked by caliche cover.

Proposed drill targets have been designed to testcovered areas within the northern portion of the project wheregeochemical, geophysical and geological indicators suggest thecontinuation of mineralization at depth.

Based on the current distribution of anomalous surfacesamples and geological interpretation, the Company considers theprincipal target corridor to extend for approximately 750 metres instrike length and up to 450 metres in width beneath partial calichecover.

Alejandro Ly, Vice President Exploration of Radius, stated:

“Permitting at Tierra Roja continues to advance andrecent surface sampling confirms that copper mineralization extendsbeneath caliche cover, expanding the footprint of the system. Ourgeological, technical and permitting work are progressing in parallelas we continue improving our understanding of the controls onmineralization and preparing the project for its planned initial drillprogram.”

Sampling, Analytical Procedures andQA/QC

Surface sampling at Tierra Roja includes rock samples,trench samples and samples collected from shallow excavations duringmultiple reconnaissance campaigns completed by previous operators andby Radius. Radius has reviewed the available historical surfacesampling database and has undertaken confirmation sampling that isconsistent with the copper and silver geochemical anomalies identifiedto date on the project. Samples collected by Radius were analyzed byindependent laboratories using established analytical and QA/QCprocedures. As exploration advances, Radius will continue to applyindustry-standard sampling and analytical protocols and followrecognized QA/QC practices in accordance with applicable regulatoryrequirements.
