Silver Added to USGS 2025 List of Critical Minerals

Apollo Silver Corp. (‘ Apollo Silver ‘ or the ‘ Company ‘) (TSX.V:APGO, OTCQB:APGOF, Frankfurt:6ZF) is pleased to announce that the US Department of the Interior has added 10 minerals, including silver, to the US Geological Survey (‘USGS’) 2025 List of Critical Minerals. For the first time, silver is recognized as having growing importance to US economic and national security. This inclusion signals enhanced government focus on securing domestic supply chains through enhanced permitting, subsidies, and strategic stockpiling initiatives.

‘Apollo Silver welcomes the US government’s efforts to strengthen domestic silver mining by placing silver on the USGS List of Critical Minerals,’ stated Ross McElroy, President and CEO of Apollo Silver. ‘This development will not only bring increased investor attention to the sector but will also help boost Apollo’s profile of its Calico Silver Project, which hosts the country’s 2nd largest primary silver deposit in the US. The inclusion of silver on the Critical Minerals List strengthens the project’s case for consideration under the Fast-41 program, a US government initiative aimed at streamlining permitting processes for critical and resource projects. With the US importing 64% of its silver consumption in 2024, this designation emphasizes silver’s strategic value and irreplaceable role across both industrial and defense industries.’

Apollo Silver’s Calico Project, located in San Bernardino County, California, recently announced its updated Mineral Resource Estimate (‘MRE’), with a combined Measured and Indicated total of 55 million tonnes (‘Mt’) at a grade of 71 grams per tonne (‘g/t’) for a total of 125 million ounces (‘Moz’) of silver (‘Ag’), and an Inferred total of 17.6 Mt at a grade of 71g/t Ag for a total of 58 Moz Ag (see Apollo’s news release dated September 4, 2025, and October 16, 2025).
