Radius Gold defines large silver system at California Target, Amalia Project, Mexico

December 15, 2021

Vancouver, British Columbia – Radius Gold Inc. (TSXV:RDU) is pleased to report results from the California target at the Amalia Project, Mexico (Figure 1). Radius has defined an extensive zone of both high grade and disseminated silver gold mineralization in its initial drill program at the California target (Figure 2 and Table 1).

The initial 14-hole, 3814m drill program intersected multi-phase breccia and stock-work vein systems with significant widths and high grades up to 4210 g/t Ag and 33.1 g/t Au. All assays have now been received and the drill rig moved to the El Cuervo target where drilling is in progress.

New drill results include:

87.25m @ 60 g/t Ag
10.95m @ 104 g/t Ag
3.10m @ 165 g/t Ag
3.30m @ 187 g/t Ag

Bruce Smith, Radius CEO, comments, "The results from California are a great advance for the Amalia Project, with multiple intersections over 1km of strike including:

AMDD21-034

3.95m @ 487 g/t Ag and 2.15 g/t Au

AMDD21-038

11.20m @ 379 g/t Ag and 1.26 g/t Au

AMDD21-039

26.90m @ 353 g/t Ag and 2.59 g/t Au

AMDD21-043

12.75m @ 259 g/t Ag and 0.54 g/t Au

AMDD21-044

19.05m @ 346 g/t Ag and 0.63 g/t Au

The system remains open to expansion along strike and to depth and so far has only been drilled on 200m centers. With the San Pedro zone drill defined and infill drilling planned for next year at California, we will be in a position to define a significant resource at the Amalia Property. With drilling on-going at the El Cuervo target and many targets remaining to drill test (Oro Viejo, La Caverna, California SE), 2022 will be an exciting year for Radius."

Drilling is currently in progress at El Cuervo target, which is a previously untested, subparallel structure where stockwork veining and brecciation has been mapped up to maximum 40m wide and semi-continuously for 1.5km. Surface rock chip samples at El Cuervo range from below detection to 637 g/t Ag and 2.24 g/t Au. PAS is operating the El Cuervo drill program and expects to complete 3500m of drilling in the first program at the target.

The Agreement

Pursuant to an option agreement signed in June 2018, Pan American Silver Corp. has the option to earn up to an initial 65% interest in the Amalia Project by making cash payments to Radius totalling US$1.5 million (of which US$800,000 has been received) and expending US$2 million on exploration over four years. Pan American may earn an additional 10% by advancing the property to preliminary-feasibility.

Quality Assurance and Quality Control

Drilling is carried out using NQ and HQ size tooling. Drill core is cut in half using a rock saw with one-half of the core then taken as a sample for analysis. Sample intervals are generally 1m intervals, producing samples of between 2 to 9 kg. Half-core samples are delivered to the ALS Geochemistry laboratory facilities in Chihuahua, Mexico. The samples are fire assayed for Au and are analysed for Ag and multi-elements using method code ME-ICP61 following a four-acid digestion. Overlimits are analysed using an appropriate method. Multi-element geochemical standards and blanks are routinely entered into the drill core sample stream to monitor laboratory performance. Quality control samples submitted to ALS were returned within acceptable limits.
