Project Highlights:

• Large scale historic underground bulk silver mining operation from 1800's.
• Silver mantos occur over 500m x 300m area (exposed in historic mines) with observed thickness up to 30m.
• Recently re-discovered by Radius, never tested by modern exploration methods.
• Initial metallurgical tests indicate exceptional properties with cyanide leach recoveries averaging 93% for silver and in combination with flotation achieving 97% silver recovery (see news release January 30, 2023).
• Initial, minimum 2000m drill program fully funded by Minera San Julian (see news release March 5, 2024).

Vancouver, British Columbia – Radius Gold Inc. (TSXV: RDU) (“Radius” or the “Company”) is pleased to announce that diamond drilling has commenced at the Plata Verde silver project in Chihuahua, Mexico. Radius, in partnership with Minera San Julian, S.A. de C.V. (“Minera San Julian”), a wholly owned subsidiary of Fresnillo plc (“Fresnillo”) plan to complete a minimum of 2000m of diamond core drilling targeting bulk minable, underground silver resources at the historic Plata Verde mines. The drill program is fully funded by Minera San Julian as part of the option agreement (see news release, March 5, 2024) signed between the companies to jointly explore Plata Verde.

Bruce Smith, Radius Gold President and CEO, commented: “The Radius Gold team is excited to get started drilling at Plata Verde. The large-scale historic silver mines have never been drill-tested and are compelling targets. As one of the largest silver producers in the world, our partner, Fresnillo, brings significant expertise to this exploration program and our project team. We are encouraged by the results of surface and underground chip sampling, the metallurgical program, and the project’s history of bulk tonnage underground silver production. The large scale excavations inside these mines indicate that the historic miners were into a significant mineralized system and the clearly visible banded silver sulphides found on the walls and roofs of the mines add to our confidence in making a discovery at this project.”

Following the completion of the first-pass diamond drilling, additional drilling will be based on results, to be confirmed by the Radius and Fresnillo joint technical committee. Silver mineralization occurs as massive to crustiform banded barite calcite and quartz with silver chlorides, sulphosalt minerals and native silver infilling and cementing fractures and breccia within a basaltic/andesite extrusive volcanic. The basaltic/andesite host occurs at the base of the Upper Rhyolitic Volcanics of the Northern Sierra Madre.

A historic extensive network of anastomosing mining tunnels and cavities was completed by hand with hammer, chisel and black powder explosives, leaving behind large underground cavities up to 50m x 50m x 30m high. Throughout the mines roman numerals painted on the walls record up to 58 mining areas. The mining excavations define a strike extension of over 500m and up to 300m wide. The host volcanic unit is at least 60m thick.

Silver mineralization is observed within mantos with multiple large scale breccia zones, fracture fill, stockwork and disseminated style mineralization within the volcanic host. Drilling will target extensions of the manto systems and also feeder systems below the mantos.

Plata Verde Project

The Plata Verde project, located in Chihuahua, Mexico, was re-discovered by Radius Gold, and is a historic, large-scale, underground, bulk tonnage silver mining operation. Plata Verde is located east of the historic Batopilas silver mining district (1708 to 1920) which reputedly produced over 300 million ounces of silver from high grade veins and structures.
