Amalia Project, Mexico

High-grade gold–silver veins in Chihuahua. Radius 35%, Pan American Silver 65%.

Chihuahua, Mexico Gold, silver Partner discussions

Amalia is a high-grade epithermal gold-silver system hosted in veins, breccias and stockwork at the contact between rhyolite and andesite. Radius made the discovery and optioned the project to Pan American Silver in June 2018. Together they completed 67 drill holes totaling 23,058 m. Selected intercepts are in the table below.

Location

Amalia is in the Sierra Madre, 25 km southwest of the historic Guadalupe y Calvo district. Mineralization follows a regional fault for more than 10 km of strike and over 1 km vertically.

Targets

The ~10,000-hectare package includes three major structures—Amalia, California and El Cuervo—with multiple untested targets still open along strike and at depth.

Best intercepts for each structure:

  • Amalia — 44 m @ 12.39 g/t Au and 309 g/t Ag
  • California — 26.9 m @ 2.59 g/t Au and 353 g/t Ag
  • El Cuervo — 13.55 m @ 10.25 g/t Au and 841 g/t Ag

Status

Pan American Silver earned a 65% interest by paying US$1.5 million in cash and completing US$2 million of exploration. The option was granted in June 2018; the earn-in was completed by the August 2022 El Cuervo results. Radius retains 35%. No material work has been completed since late 2022. Discussions with Pan American Silver continue as Radius evaluates options to realize value from the project.
