Radius Gold Accelerates Exploration at Tierra Roja with Integrated Hyperspectral, Geophysics and Geochemistry Programs

(TheNewswire)

April 29, 2025 – TheNewswire - Vancouver, Canada – Radius Gold Inc. (TSXV: RDU) ("Radius" or the"Company") is pleased to provide an update on explorationand targeting at Tierra Roja and its consolidated 8,170 hectare landposition in southern Peru. The Company is advancing an integratedprogram of remote hyperspectral surveys, high resolution geochemistry,geophysics and field mapping to accelerate exploration across adistrict scale at low cost.

Radius has secured the rights to a total of 8,170hectares through a combination of option agreements, new claimstaking, and exclusivity agreements. This includes 3,670 hectares ofcontiguous ground at the Tierra Roja target, and an additional 4,500hectares across three regional properties currently under exclusivityagreements for evaluation and potential future optioning.

At Tierra Roja, Radius has completed detailedgeological mapping of lithology and hydrothermal alteration, formingthe basis for a broader regional exploration initiative. To rapidlyassess its expanded land position, Radius recently completed anAI-driven hyperspectral remote sensing survey, integrating data frommultiple satellite platforms (see Figures 1 to 3 below). The satelliteanalysis was anchored by detailed field mapping at Tierra Roja andapplied not only across the Company’s 8,170 ha land package, butalso across the entire southwestern Peru porphyry district. Radius hasa team in the field currently evaluating newly generatedtargets.

In parallel, Radius has completed a detailedgeochemical sampling grid at Tierra Roja, utilizinglow-detection-limit assays for 49 elements (assay results pending).Historical sampling at Tierra Roja was limited to mostly copper andthis new dataset will assist in geochemical zonation, refine drilltargets, and serve as a reference tool as Radius evaluates its broaderregional portfolio.

The integrated approach has enhanced Radius’sunderstanding of mineralization at Tierra Roja, expanded knowntargets, and generated new regional targets for evaluation andpotential acquisition.

To further support drill targeting, the Company hascontracted GC-Ground geophysical consultants to conduct a focusedInduced Polarization (IP) and Resistivity survey at Tierra Roja. Thisprogram is expected to commence within the next month. Radius is alsoconfident that drill permits will be received within this same timeframe, keeping the Company on track for an initial drill programwithin the next months.

Bruce Smith, President and CEO of Radius Gold,commented:

“Most geologists have used some form of remotesensing, ASTER, or spectral surveys, but this is the first time I’vehad access to global scale combined datasets from multiple satelliteson a single platform, integrated with AI-assisted target generation.It’s allowing us to verify and update our geological mapping at adetailed project level, then rapidly search for similar targets acrossa regional scale. Radius is combining this advanced remote sensingwith high-resolution multi-element geochemistry and geophysics tobuild a complete targeting framework. Our goal is to drill Tierra Rojawithin the coming months while continuing to generate and evaluate newtargets across the district.”
