Radius Gold Accelerates Exploration at Tierra Roja with Integrated

Hyperspectral, Geophysics and Geochemistry Programs

Vancouver, Canada – Radius Gold Inc. (TSXV: RDU) ("Radius" or the "Company") is pleased to provide an

update on exploration and targeting at Tierra Roja and it s consolidated 8,170 hectare land position in

southern Peru. The Company is advancing an integrated program of remote hyperspectral surveys, high

resolution geochemistry, geophysics and field mapping to accelerate exploration across a district scale at

low cost.

Radius has secured the rights to a total of 8,170 hectares through a combination of option agreements,

new claim staking, and exclusivity agreements. This includes 3,670 hectares of contiguous ground at the

Tierra Roja target, and an additional 4,500 hecta res across three regional properties currently under

exclusivity agreements for evaluation and potential future optioning.

At Tierra Roja, Radius has completed detailed geological mapping of lithology and hydrothermal

alteration, forming the basis for a broader regional exploration initiative. To rapidly assess its expanded

land position, Radius recently completed an AI -driven hyperspectral remote sensing survey, integrating

data from multiple satellite platforms (see Figures 1 to 3 below). The satellite analysis was anchored by

detailed field mapping at Tierra Roja and applied not only across the Company’s 8,170 ha land package,

but also across the entire southwestern Peru porphyry district. Radius has a team in the field currently

evaluating newly generated targets.

In parallel, Radius has completed a detailed geochemical sampling grid at Tierra Roja, utilizing low -

detection-limit assays for 49 elements (assay results pending). Historical sampling at Tierra Roja was

limited to mostly copper and this new dataset will assist in geochemical zonation, refine drill targets, and

serve as a reference tool as Radius evaluates its broader regional portfolio.

The integrated approach has enhanced Radius’s understanding of mineralization at Tierra Roja, expanded

known targets, and generated new regional targets for evaluation and potential acquisition.

To further support drill targeting, the Company has contracted GC-Ground geophysical consultants to

conduct a focused Induced Polarization (IP) and Resistivity survey at Tierra Roja. This program is expected

to commence within the next month. Radius is also confident that drill permits will be received within this

same time frame, keeping the Company on track for an initial drill program within the next months.

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

“Most geologists have used some form of remote sensing, ASTER, or spectral surveys, but this is the first

time I’ve had access to global scale combined datasets from multiple satellites on a single platform,

integrated with AI-assisted target generation. It’s allowing us to verify and update our geological mapping

at a detailed project level, then rapidly search for similar targets across a regional scale. Radius is

combining this advanced remote sensing with high -resolution multi -element geochemistry and

geophysics to build a complete targeting framework. Our goal is to drill Tierra Roja within the coming

months while continuing to generate and evaluate new targets across the district.”
