Detailed Coverage of the Calico Silver Project's Transformative Update

The recently filed NI 43-101 Technical Report for Apollo Silver Corp.'s (TSX-V: ASR) Calico Silver Project, effective June 30, 2025, and filed on October 16, 2025, marks a monumental step in the project's development. This comprehensive report, prepared by Stantec Consulting Ltd., significantly updates the Mineral Resource Estimate (MRE), solidifying Calico's position as a major player in the North American silver landscape.

Specifically, the report details a substantial increase in silver resources. The combined Measured and Indicated (M&I) resources at the Waterloo property now stand at 55 million tonnes (Mt) at an average grade of 71 grams per tonne (g/t) silver (Ag), containing an impressive 125 million ounces (Moz) Ag. This represents a 61% increase in tonnage and a 14% increase, or an additional 15 Moz, in contained silver compared to the previous MRE. Furthermore, the Langtry deposit, also part of the Calico Project, contributes an additional 57 Moz Ag in the Inferred category from 24 Mt at 73 g/t Ag. The report also notes an 86% increase in the gold resource within the Inferred category.

A groundbreaking aspect of this updated MRE is the inaugural estimation of barite (BaSO4) and zinc (Zn) resources, both designated as critical minerals by the U.S. government. The project now boasts Indicated resources of 2.7 Mt of barite and 354 million pounds (Mlbs) of zinc, alongside Inferred resources of 0.65 Mt of barite and 258 Mlbs of zinc. This multi-mineral discovery significantly enhances the project's strategic value, aligning with national priorities for critical mineral security and diversifying its commodity exposure beyond just silver. The shallow depth of mineralization at Calico, coupled with a favorable low strip ratio of 0.8:1 for a single pit at the Waterloo deposit, further underscores its economic viability.

The journey to this updated MRE involved several key milestones. Apollo Silver announced its maiden MRE for Calico in February 2022, followed by an updated MRE in March 2023, which saw a 95% conversion of Inferred silver ounces to Measured and Indicated. The latest MRE, first announced on September 4, 2025, incorporates updated commodity prices, mining costs, and barite testing of existing drill samples from the Waterloo Property, even without new drilling since the 2023 MRE. Key players in this advancement include Apollo Silver's President and CEO, Ross McElroy, and the team of Qualified Persons from Stantec Consulting Ltd., including Derek Loveday, P. Geo., Johnny Marke, P.G., and Mariea Kartick, P. Geo.

Initial market reactions have been mixed but generally positive, reflecting the complexity of evaluating a development-stage project. While some AI analysts provided a "Neutral" impact rating, Apollo Silver's management emphasized that the increased silver and gold quantities, coupled with the inclusion of critical minerals, have substantially "de-risked" the project. This de-risking is expected to be a cornerstone for the upcoming Preliminary Economic Assessment (PEA). The company's share price has seen significant appreciation, climbing 60% over the past month and an impressive 354% over three years, indicating growing investor confidence in its expanded resource potential and strategic direction.

Companies That Might Win or Lose from the Event

The updated NI 43-101 Technical Report for Apollo Silver's (TSX-V: ASR) Calico Silver Project is poised to create distinct winners and losers within the mining sector and related industries, with Apollo Silver itself standing as the primary beneficiary. The report's findings have significant financial and operational implications that will ripple through the market.

Apollo Silver (TSX-V: ASR) is undoubtedly the biggest "winner" from this development. Financially, the substantial increase in Measured and Indicated (M&I) silver resources to 125 million ounces (Moz) at Waterloo, alongside an additional 57 Moz at Langtry, significantly enhances the company's asset valuation. This 14% increase in contained silver ounces and 61% increase in tonnage at Waterloo, compared to the March 2023 MRE, provides a much stronger foundation for future economic studies. Crucially, the inaugural inclusion of barite and zinc—both designated as critical minerals by the U.S. government—adds significant by-product credits, with Indicated resources of 2.7 Mt of barite and 354 million pounds (Mlbs) of zinc. This diversification, along with an 86% increase in inferred gold resources, de-risks the project and enhances its revenue potential. Operationally, the low strip ratio of 0.8:1 at Waterloo signals efficient open-pit mining potential, which will positively impact the upcoming Preliminary Economic Assessment (PEA) and aid in securing project financing. The expansion of its land package by over 285% through the acquisition of the Mule claims further provides exploration upside along the mineralized Calico Fault System, while the project's location in mining-friendly San Bernardino County, California, with existing infrastructure, offers strategic advantages.

Among other silver mining companies, the impact is more nuanced. The overall silver sector could see a boost in investor confidence, potentially attracting more capital to other silver explorers and producers, especially those in stable jurisdictions like the U.S. Companies with similar multi-metal deposits that include critical minerals may also see their assets re-rated as the market recognizes the added value of these strategic commodities. Notably, Pan American Silver Corp. (TSX: PAAS; NYSE: PAAS) stands to benefit directly, as it holds a 2% net smelter return (NSR) royalty on Apollo Silver's Waterloo property. However, the Calico Project's strong, de-risked profile could intensify competition for capital, potentially drawing investment away from smaller, less advanced, or higher-cost silver projects, making them appear less attractive by comparison. Large, established silver producers with diversified portfolios might see less direct impact unless Calico reaches production and significantly alters global silver supply dynamics.

Related industries and ETFs also stand to gain. Mining equipment and services companies will see increased demand for everything from drilling equipment to engineering consulting as Calico moves towards development and production. Industries reliant on barite (e.g., oil and gas drilling, medical) and zinc (e.g., galvanizing, batteries) could benefit from a new, potentially significant domestic supply, reducing reliance on imports. Silver-focused Exchange-Traded Funds (ETFs) such as the Global X Silver Miners ETF (SIL), Amplify Junior Silver Miners ETF (SILJ), or the Sprott Silver Miners & Physical Silver ETF (SLVR) could experience increased inflows and improved performance as investor sentiment towards silver mining strengthens. Finally, the local economy of San Bernardino County, California, will likely see job creation, infrastructure development, and increased economic activity as the project advances. Conversely, existing suppliers of imported barite and zinc to the U.S. market might face increased competition from Calico's potential domestic output. While not an immediate concern, a significant new source of physical silver could, in the long term, influence the dynamics of "paper silver" markets and physically-backed silver ETFs.

Wider Significance of the Calico Project Update: A Strategic Shift in Domestic Mineral Supply

Apollo Silver's (TSX-V: ASR) updated NI 43-101 Technical Report for the Calico Silver Project transcends a mere company announcement; it represents a pertinent event within the broader context of the United States' strategic drive to secure domestic critical mineral supplies. The report, filed on October 16, 2025, with an effective date of June 30, 2025, not only significantly boosts silver resources but, more critically, establishes an inaugural resource for barite and zinc, both designated as vital critical minerals by the U.S. government.

This multi-commodity nature of the Calico Project strongly aligns with current broader industry trends focused on addressing U.S. critical mineral vulnerability and strengthening domestic supply chains. The U.S. faces significant import reliance for many critical minerals, including approximately 85% for barite in 2023. Barite is crucial for energy independence and national security infrastructure, particularly in hydrocarbon production, while zinc is also on the 2022 critical minerals list. Furthermore, silver itself has been recommended for inclusion in the draft 2025 critical minerals list, underscoring its growing strategic importance in modern technologies and the energy transition. By offering a significant domestic source for these materials, Calico directly contributes to reducing foreign dependency and enhancing the resilience of American supply chains.

The potential ripple effects of this development are substantial. For competitors, while a new large domestic silver source is unlikely to create an oversupply given the U.S.'s import reliance, it could increase competition for market share. More significantly, for critical minerals like barite, a new domestic source could provide a more stable and potentially cost-competitive alternative to foreign suppliers, potentially putting pressure on international producers and encouraging further domestic exploration. Downstream industries, particularly those reliant on silver (electronics, solar), barite (oil and gas, medical), and zinc (galvanizing, batteries), stand to benefit immensely from enhanced supply chain security, mitigating risks associated with geopolitical instability and trade disruptions. This local production also fosters economic development, creating jobs and stimulating activity in San Bernardino County, California.

From a regulatory and policy standpoint, the Calico Project's status as a source of critical minerals is likely to attract continued federal attention and potential support under U.S. policies designed to secure critical mineral supply chains. This could include expedited permitting under initiatives like FAST-41, eligibility for grants, loans, and tax credits, and prioritization in federal investment strategies, even while navigating California's stringent environmental regulations. Historically, significant mineral discoveries in the U.S., such as the Comstock Lode or the California Gold Rush, have triggered massive economic development and shifts in national resource focus. While modern in its systematic development, Calico's potential to establish a large domestic source of key minerals echoes the long-term impact of such historical discoveries on the national resource landscape, reinforcing a strategic imperative similar to wartime efforts to ramp up domestic production of essential materials. The polymetallic nature of Calico, producing silver, gold, barite, and zinc, also reflects a common and economically advantageous geological characteristic, enhancing its overall value and resilience to single-commodity price fluctuations.

What Comes Next for Apollo Silver and the Market

The updated NI 43-101 Technical Report for Apollo Silver's (TSX-V: ASR) Calico Silver Project sets a clear trajectory for the company and underscores the dynamic future of the broader silver market. With an effective date of June 30, 2025, and filed on October 16, 2025, the report marks a pivotal point, propelling Calico towards significant development and positioning it within a bullish silver market characterized by persistent supply deficits and surging demand.

In the short-term, Apollo Silver's immediate focus will be on the upcoming Preliminary Economic Assessment (PEA). This crucial study will integrate the significantly increased silver resources (125 Moz M&I at Waterloo) and the newly identified critical mineral resources (2.7 Mt barite and 354 Mlbs zinc) into comprehensive project development plans. The PEA is essential for demonstrating the project's robust economic viability and de-risked profile, aided by the favorable low strip ratio of 0.8:1 at Waterloo and shallow mineralization. Concurrently, the company plans further drilling and exploration to expand silver mineralization, upgrade barite and zinc resources through infill drilling, and target high-grade gold structures, leveraging the 86% increase in inferred gold ounces. Advancing permitting and engineering studies will also be key milestones.

Looking long-term, the possibilities for Calico are substantial. With a de-risked and expanded resource base, the vision is to develop a low-impact open-pit mining operation. The potential for further resource expansion, both at depth and along strike, particularly at the Langtry Property, remains strong. The inclusion of critical minerals could attract strategic partnerships and off-take agreements, further de-risking future production and providing stable revenue streams. Successful progression through these stages would facilitate future capital raises necessary for full-scale development and construction.

Strategic pivots or adaptations will be crucial for Apollo Silver. The company must effectively integrate the development plans for silver, gold, barite, and zinc, optimizing mining and processing strategies for multi-commodity extraction. Navigating California's stringent environmental regulations and permitting processes will be paramount, though the critical mineral designation for barite and zinc could potentially provide regulatory tailwinds. Strategic capital allocation between Calico and its Cinco de Mayo Project in Mexico, along with strong community engagement and robust ESG practices, will also be vital for long-term success.

For the broader silver market, significant opportunities are emerging. The market has been in a structural supply deficit for seven consecutive years, with 2025 projected to see a shortfall of 118-240 million ounces. This persistent imbalance is expected to drive prices higher. Industrial demand, now accounting for over half of annual consumption (59% in 2024), is surging, fueled by the green economy (solar panels, EVs), advanced electronics, and AI. Investment demand also remains strong, as silver acts as both an industrial metal and a safe-haven asset. Analysts widely forecast strong price appreciation, with some projections reaching $75-$77 per ounce by 2026-2027.

However, challenges persist. Supply constraints due to declining mine output and the byproduct nature of much of silver production limit supply elasticity. Historical underinvestment in exploration has led to a limited pipeline of new primary silver mines. Operational challenges, regulatory hurdles, and price volatility remain inherent risks. Despite these, the overall outlook for silver appears robust, driven by fundamental supply-demand dynamics.

For investors, several scenarios could unfold. A bullish scenario sees Calico advancing rapidly, becoming a key producer in a surging silver market, leading to significant stock re-rating for Apollo Silver and potentially making it an acquisition target. A moderate scenario involves steady project progression and gradual stock appreciation, with silver prices consolidating within the $40-$55 range. A bearish scenario could involve unforeseen regulatory delays, significant cost overruns, or a weakening silver market, impacting project economics and potentially leading to financing difficulties and shareholder dilution. Investors should closely monitor the PEA results, subsequent exploration, and the broader macroeconomic environment to navigate these possibilities.
