Drilling commences at Radius Gold’s Plata Verde silver project

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 basal tic/andesite extrusive volcanic.

The basaltic/andesite host occurs at the base of the Upper Rhyolitic Volcanics of the Norther n 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.
