Apollo Reports High-Grade Silver, Gold and Barite Results at Calico

Apollo Silver Corp. has announced encouraging results from its ground geological mapping and sampling program at the Calico Silver Project in San Bernardino County, California. The program, which included 245 rock samples and 893 soil samples collected in December 2025, has identified multiple mineralized occurrences with highly anomalous precious metal and barite values across several key areas of the project.

The most significant results came from the Mule Property, where outcrop samples from the Pickhandle Formation volcanic rocks returned exceptional silver grades of up to 1,280 g/t and 221 g/t. These high-grade samples were associated with felsic volcanic tuffs hosting dark purple barite veinlets, confirming the Pickhandle Formation as an important exploration target warranting systematic follow-up. At the Burcham mine area within the Waterloo Property, infill rock sampling returned multiple anomalous gold results including 4.85 g/t, 3.70 g/t, and 3.59 g/t Au, along with high-grade zinc values up to 30.0% in specularite manto zones.

The program also confirmed significant barite mineralization potential, with assays returning up to 76.12% BaSO4 at Langtry and 35.68% BaSO4 at Waterloo. These results are particularly noteworthy as barite already comprises part of the Mineral Resource Estimate at Waterloo, while less was previously known about barite occurrence at Langtry. The discovery of anomalous barite mineralization at Langtry opens up additional resource potential for the project.

Looking ahead, Apollo Silver continues to advance both exploration and project development initiatives. The company is proceeding with a Preliminary Economic Assessment expected to be completed in Q3 2026, while also planning a 4,500m HQ diameter drill program for metallurgical and geotechnical work and a 1,000m NQ diameter exploration program to test Burcham gold potential. Although drilling was originally scheduled for Q1 2026, activities have been rescheduled to Q3 due to permitting delays and seasonal high temperature constraints that limit operations during summer months. These results reinforce the upside prospectivity for additional discoveries at Calico and support the project's potential for resource expansion across multiple commodities.
