High-grade gold–silver veins in Chihuahua. Radius 35%, Pan American Silver 65%.
Amalia is a high-grade epithermal gold-silver system 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, hosted in veins, breccias and stockwork at the contact between rhyolite and andesite. 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.
Radius made the discovery and, with Pan American Silver, completed 67 drill holes totaling 23,058 m. Highlight intercepts include 44 m of 12.39 g/t gold and 309 g/t silver on the Amalia vein, 26.9 m of 2.59 g/t gold and 353 g/t silver at California, and 13.6 m of 10.25 g/t gold and 841 g/t silver at El Cuervo.
Best grade × width intercept for each vein system.
| Vein system | Hole | Gold (g/t) | Silver (g/t) |
|---|---|---|---|
| Amalia | AMDD19-010 | 12.39 | 309 |
| California | AMDD21-039 | 2.59 | 353 |
| El Cuervo | AMDD22-066 | 10.25 | 841 |
Held. Not an active Radius program. Pan American has earned a 65% interest; Radius retains 35%. No material work has been completed since late 2022. Discussions with Pan American continue as Radius evaluates options to realize value from the project.
