Apollo Silver (TSXV:APGO,OTCQB:APGOF,FSE:6ZF0) is a silver-focused exploration company advancing a dual-asset strategy through two high-potential projects in North America: the Calico Silver Project in California, USA, and the Cinco de Mayo project in Chihuahua, Mexico. Both projects are situated in mining-friendly jurisdictions with robust infrastructure and a history of significant exploration work.
At Calico, Apollo Silver advances the Waterloo deposit through geological modeling, barite resource definition, and engineering studies. Calico hosts 110 Moz of silver (measured and indicated) and 51 Moz (inferred), with recent test work producing a 94.6 percent barite concentrate.
In Mexico, the Cinco de Mayo project offers rare optionality, featuring a historical inferred resource of 154 Moz silver equivalent (385 g/t) and a high-impact discovery opportunity at the Pegaso Zone. Under an option agreement with MAG Silver, Apollo is executing a 20,000-meter drill program to earn full ownership of the project.
Project locations
The Calico Silver Project, located 15 km from Barstow, California, includes the adjacent Waterloo and Langtry properties. Calico hosts a combined resource of 110 Moz silver (measured and indicated, 100 g/t) and 51 Moz silver (inferred, 77 g/t). The shallow, laterally extensive deposit offers strong geologic continuity and a low 1.1:1 strip ratio, supporting a potential low-impact open-pit operation. Recent drilling confirmed a 95 percent conversion rate from inferred to measured and indicated resources at Waterloo.
Company Highlights
- Tier-1 US Silver Asset – Calico Project: Hosts 110 Moz silver (measured and indicated) and 51 Moz silver (inferred), making it the largest undeveloped primary silver deposit in the US.
- High-grade Discovery Potential – Cinco de Mayo: An option to acquire a district-scale carbonate replacement deposit with a historical inferred resource of 154 Moz silver equivalent at 386 g/t, offering further upside from the Pegaso Zone discovery target.
