High Quality Barite Confirmed At Calico Silver Project

VANCOUVER - Apollo Silver Corp. reported on the barite flotation test work and quality analysis, completed as part of its 2022 Metallurgical Test Program (the “2022 Test Program”) for the Waterloo silver-barite deposit. The 2022 Test Program is an initial investigation in the metallurgical process response of silver-barite mineralized rock at the Calico Silver Project, located in San Bernardino County, California.

Highlights: Concentrate with up to 94.6% barite produced by flotation; and Barite concentrate meets or exceeds the standards for chemical and physical specifications for drilling fluids for use in the petroleum industry as defined by the American Petroleum Institute (API).

“These results confirm that barite has the potential to make a meaningful contribution to development potential at Calico,” said President and CEO, Tom Peregoodoff. “In addition to its potential as a meaningful by-product credit, the production of a salable barite product has the potential to make a material reduction in the waste produced from future silver mining operations. Barite pricing is typically strongly impacted by transportation costs and Calico’s proximity to the major rail transportation hub at Barstow significantly opens up the potential market for Calico sourced barite.”
