Investor Insight

Apollo Silver is advancing two high-impact silver projects in premier North American jurisdictions—California and Mexico—offering investors a unique combination of scale, optionality, and leverage to silver and critical mineral demand.

Overview

Apollo Silver (TSXV:APGO,OTCQB:APGOF,FSE: 6ZF0) is a silver-focused company advancing a dual-asset strategy centered on two high-impact projects in North America: the Calico silver project in California, USA and the Cinco de Mayo project in Chihuahua, Mexico. Both are located in mining-friendly jurisdictions with strong infrastructure and significant historical work.

At Calico, Apollo Silver is advancing the Waterloo deposit toward development through geological modeling, barite resource definition, and engineering studies. Calico boasts 110 Moz of silver (measured and indicated) and 51 Moz of silver (inferred), and recent test work has produced a 94.6 percent barite concentrate, supporting the asset’s potential as a US critical minerals supplier.

In Mexico, Cinco de Mayo offers rare optionality with a historical inferred resource of 154 Moz silver equivalent (385 g/t), and a potentially game-changing discovery at the Pegaso Zone. The project is under an option agreement between Apollo Silver and MAG SIlver, wherein Apollo Silver will complete a 20,000-meter drill program to convert the option to an acquisition of the Cinco de Mayo. Apollo Silver’s strategy is underpinned by disciplined capital allocation, high-impact exploration, and a proven ability to acquire and unlock value from high-quality assets—following a model similar to Prime Mining. With no debt, strong institutional backing, and an experienced team, Apollo Silver is well-positioned to deliver scalable, discovery-driven growth in a rising silver and critical minerals market.

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.
• Barite Critical Minerals Exposure: Calico includes a historical in-ground barite estimate of 4.5 Mt, with 2023 flotation tests producing 94.6 percent barite concentrate, meeting US estimates API specifications for petroleum drilling fluids.
• Strategic Shareholder Registry: Backed by Jupiter Asset Management, Eric Sprott, Terra Capital, Commodity Capital and Ninepoint.
• Experienced Leadership Team: Proven M&A, discovery and capital markets expertise with over $5 billion in past transactions and most applicable to Apollo Silver, the success at Prime Mining.

Key Projects

Calico Project

The Calico silver project comprises two adjacent properties—Waterloo and Langtry—located in mining-friendly San Bernardino County, 15 km from Barstow, California. The combined resource at Calico includes 110 Moz of silver in the measured and indicated category (average grade: 100 g/t) and 51 Moz of silver in the inferred category with an average grade of 77 g/t. The deposit is shallow, laterally extensive, and exhibits excellent geologic continuity. A low strip ratio of 1.1:1 supports a potential open-pit operation with minimal environmental footprint. Drilling has demonstrated strong correlation between 2022 results and historical intercepts, underpinning a 95 percent conversion rate from inferred to measured and indicated categories at Waterloo.

Resources at Calico sit primarily on private land with vested mining rights, simplifying the path to permitting. Infrastructure is excellent: paved roads, power lines within 5 km, and proximity to the expanding Barstow rail terminal.

In addition to silver, Apollo Silver is evaluating Calico’s potential for gold and barite. Barite, a US critical mineral essential to oil and gas drilling, has demonstrated recoveries exceeding 94.6 percent purity in prior test work. A 1979 ASARCO historical estimate indicates 4.5 Mt of barite grading 13.4 percent. Ongoing 2025 work includes a barite resource estimate, investigating potential for additional gold mineralization, depending on results of preliminary work, followed up by a small drill program to test those findings.

Cinco de Mayo Project

Cinco de Mayo is a district-scale carbonate replacement deposit (CRD) system located in Chihuahua, Mexico along the same NW-SE structural trend that hosts some of the country’s largest silver and base metal deposits. The project was historically MAG Silver’s flagship asset, hosting a historical NI 43-101 compliant inferred resource of 154 Moz silver equivalent at an average grade of 386 g/t silver equivalent, including 132 g/t silver, 6.47 percent zinc, and 2.86 percent lead across the Jose Manto and Bridge Zone targets.

The site also includes the Pozo Seco deposit, which hosts an additional historical resource of 230,000 oz gold and 94 million pounds molybdenum, based on a 2010 technical report. Notably, a significant mineralized intercept—61 meters of massive sulphides—was drilled by MAG Silver in the Pegaso Zone beneath the known resource but never followed up due to social access issues.

Apollo Silver has secured an option to acquire the property from MAG Silver and is actively re-engaging with the local community to secure surface access to the property. A new, development-friendly ejido administration was elected in December 2024. The company is now pursuing a mutually beneficial and meaningful agreement with the local community for surface access rights to the Cinco de Mayo. The company will then execute a 20,000-meter drill campaign once access is secured. Under the option agreement with MAG Silver, Apollo Silver must secure access, drill 20,000 meters, and issue 19.99 percent of its common shares to complete its option to acquire Cinco de Mayo. Priority targets include Pegaso and expansion zones at Jose Manto. Metallurgical studies and engineering reviews are being considered as part of a future resource update.
