Vancouver, Canada – TheNewswire – July 7th, 2025 - Radius Gold Inc. (TSXV: RDU) ("Radius" or the "Company") is pleased to announce that it has received permits for drilling at its 100%-owned Tierra Roja copper project. In parallel, results from the recently completed induced polarization (IP) and resistivity geophysical surveys have defined a large coherent zone of high resistive and high chargeable material at depth below the copper mineralization defined by surface mapping and sampling. The combination of significant surface copper oxide copper mineralization, hosted in highly altered (silica, sericite) intrusive and volcanics, with a large resistive and chargeable geophysics response at depth define compelling drill targets.
Bruce Smith, President and CEO of Radius Gold, commented: "With drill permits in hand and compelling geophysical targets now defined, Radius looks forward to commencing the first-ever drill program at Tierra Roja. The IP results align well with our surface mapping and sampling, and we believe Tierra Roja has the potential to host a significant copper discovery and look forward to the start of drilling."
The Phase 1 drill program is expected to commence Q3 and will test geophysical targets, located directly below outcropping alteration and copper oxide mineralisation. See figures 1 to 4.
About the IP/Resistivity Survey
The IP/Resistivity consisted of 3 NS orientated lines, total 4.8km surveyed covering the core 800m diameter system. Initial interpretation indicates a broad and coincident resistivity and chargeable anomaly dipping south to depth from the main out cropping copper oxide mineralised zones. The geophysical chargeable and resistive anomaly is consistent line to line across 500m of tested strike extension.

Note almost co-incident chargeable and resistive anomalies. Chargeable anomaly is approximately 3X greater than background and is consistent line to line across 500m. Proposed drill hole depicted.

Geological Interpretation
Radius has now completed detailed geological mapping at Tierra Roja, along with geochemistry and both magnetic and IP/Resistivity surveys. Several zones of structurally controlled EW oriented zones intense silica, sericite dominant alteration between 50 to 150m wide are associated with copper mineralisation. Higher grade (+2% Cu) are often completely brecciated and replaced by silica. The larger zones of intense alteration are surrounded by wide zones of moderate to weak alteration and then relatively fresh rock. The outer margins of the system have chlorite epidote alteration. Mineralization occurs as copper oxides, dominantly malachite, chrysocolla, and atacamite hosted within structures and broadly disseminated. The host rocks regionally are andesitic volcanics estimated Jurassic age. The core of the target is comprised of a multi-phase intrusive complex dominantly of dacite composition, but also andesite and quartz-feldspar porphyry, estimated Cretaceous age. There is widespread faulting, brecciation and replacement of large areas (50 to 150m wide) by silica sericite alteration.
The origins of the intense alteration and copper oxide mineralization observed at surface are uncertain. Drilling is required. There has been some debate amongst our experienced Peruvian team and several visitors to the project as to whether the observed characteristics are related to porphyry copper or IOCG mineralisation. Tierra Roja lies 120km south of the large IOCG deposits Mina Justa, Marcona, Pampa de Pongo and further north Mina Raul Contestable. 200km south of Tierra Roja occur very large porphyry copper deposits in La Tapada, Tia Maria, Cerro Verde, Chapi etc.
Tierra Roja has a significant scale alteration system, abundant copper oxide mineralisation occurring over a large area, a strong co-incident IP - chargeable and resistivity anomaly extending to depth below the outcropping alteration and mineralization and has never been drill tested. The Radius team looks forward to drilling this compelling target.

Drill Permits
Radius local subsidiary in Peru has been granted FTA (Ficha Técnica Ambiental) authorizations that approves drilling and the construction of 20 drill pads and access roads. From each platform several drillholes can be completed. The FTA also covers land access and in the case of Tierra Roja, the land is federally owned with no registered occupants and access approved. There is no drilling water available on-site and water will need to be purchased and trucked in from an approved mining supply of which there are several available sources within the district. The alternative for drilling without water is RC (reverse circulation). Radius is currently negotiating drill contracts with potential suppliers.
