As the global energy landscape evolves, one material has emerged as a cornerstone for both renewable energy and defense sectors: antimony. This versatile mineral is pivotal in solar technology, battery advancements, and military applications.
However, recent geopolitical tensions have highlighted vulnerabilities in its supply chain, emphasizing the need for nations to secure sustainable sources. Companies like Military Metals Corp are stepping up to bridge the gap, ensuring antimony’s availability in an increasingly resource-scarce world.
Renewable Energy’s Secret Weapon
The transition to renewable energy relies heavily on advanced materials, and antimony is no exception. In solar panels, this mineral enhances the efficiency of perovskite solar cells by improving light absorption and charge transport. This results in higher energy conversion rates, making solar panels more effective at capturing sunlight.
Additionally, antimony compounds increase thermal stability, allowing panels to endure extreme conditions without frequent replacements.
Energy storage is another area where antimony shines. Liquid-metal batteries, a promising solution for storing solar energy, depend on antimony’s unique properties. These batteries enable efficient capture and distribution of excess solar power, addressing the intermittency challenges of renewable energy sources.
With solar installations projected to grow exponentially, antimony’s role in making this energy transition feasible cannot be overstated. The EIA projects solar capacity to reach over 300 GW by 2030 and around 700 GW by 2050.

The Silent Shield: Antimony’s Role in Defense Systems
Beyond renewable energy, antimony is indispensable to national security. The Department of Defense (DoD) uses this critical mineral in 200+ types of munitions, including percussion primers, stab detonators, and armor-piercing rounds.
Moreover, antimony alloys enhance the durability and reliability of lead-acid batteries used in military vehicles and equipment.
Antimony’s role in flame retardants further underscores its importance in defense. Military uniforms, equipment, and vehicles rely on antimony-based compounds for fire resistance, ensuring the safety of personnel in combat scenarios. Furthermore, antimony-containing semiconductors are critical for infrared sensors and night-vision devices, key technologies for modern warfare.
Breaking China’s Grip: Global Efforts to Secure Antimony Supplies
China controls nearly 50% of global antimony mining and 80% of processing, creating a bottleneck in the supply chain. Recent export restrictions by China, citing dual-use applications of the mineral for both civilian and military purposes, have exacerbated this dependence.
These restrictions pose significant challenges for countries like the United States, which relies on imports for over 80% of its antimony consumption.
China’s export controls also affect antimony’s availability for renewable energy technologies. The U.S. solar industry, a critical player in the clean energy transition, faces potential disruptions due to limited access to the material for solar panel production.
As trade tensions escalate, securing alternative sources becomes a strategic imperative. Antimony is one of the critical minerals that China restricted export more recently in October this year.
Diversifying Antimony: The Key to Supply Chain Resilience
Countries worldwide are taking steps to reduce reliance on Chinese antimony.
Over two years, global antimony drilling activity totaled 625 holes, with 88 yielding significant intervals. Australia dominated with 444 holes, including 65 significant finds, reflecting its active exploration sector. The USA followed with 44 holes and 10 significant intervals.

Other contributions came from Canada, New Zealand, and Namibia. Emerging interest in regions like Bosnia, Indonesia, and Slovakia highlights a global push to secure antimony resources, driven by rising demand in energy and defense sectors.
This data underscores strategic exploration efforts amid tight global supply chains and geopolitical tensions impacting mineral accessibility.
- In the U.S., the Department of Defense awarded $15.5 million to Perpetua Resources to explore antimony production from the Stibnite Gold Project in Idaho.
Similarly, Spearmint Resources in Canada has doubled its acreage at the George Lake South Antimony Project, recognizing the mineral’s strategic value.
Moreover, international collaboration is gaining momentum. Nations like Australia, Belgium, and India are investing in antimony processing facilities. Meanwhile, African countries such as Mozambique and Tanzania are emerging as alternative mining hubs. These efforts aim to create resilient supply chains that can withstand geopolitical shocks.
Antimony’s dual role in solar technology and defense highlights its unique importance. This underscores the need for a balanced approach to resource allocation, ensuring that both renewable energy goals and national security needs are met.
The escalating U.S.-China trade war further complicates this balance. Tariffs, export restrictions, and retaliatory measures threaten to disrupt global markets, making it imperative for industries to innovate and adapt.
Surging Prices and Market Outlook
The global antimony market is under intense pressure due to surging demand and constrained supply. In December 2024, antimony trioxide prices soared by almost 232% compared to last year, reaching $38,000 per metric ton. This is largely driven by China’s export restrictions and heightened geopolitical tensions.

The mineral’s critical role in defense, solar panels, and battery technologies has made it a highly sought-after resource.
Global demand for antimony is expected to rise sharply in the coming years, particularly as renewable energy and defense sectors expand. Analysts predict that its market value could grow significantly, driven by advancements in solar technology, energy storage, and defense applications.
Demand for this critical mineral is forecasted to reach $3.5 billion by 2030. However, the market remains vulnerable to supply chain disruptions, with China’s dominance continuing to exert influence on global prices.
Efforts to address these challenges include investments in alternative sources and recycling initiatives. Countries like the U.S. and Canada are accelerating domestic production, while companies like Military Metals Corp are spearheading exploration projects to tap into previously untapped reserves.
Military Metals Corp: Leading the Antimony Revolution
Military Metals Corp is an emerging key player in ensuring a stable antimony supply. The company’s strategic assets in Slovakia and Canada aim to reduce dependency on Chinese imports by revitalizing historical mining sites with untapped potential.
Trojarova, Slovakia: Military Metals has identified significant antimony-gold mineralization at this site, with historical estimates indicating high-grade deposits. By extending underground adits and exploring deeper veins, the company plans to unlock valuable resources for both defense and renewable energy applications.
West Gore, Nova Scotia: Once Canada’s largest antimony producer, this site holds immense potential for modern exploration. Historical data suggests significant quantities of this mineral and gold in waste dumps and tailings, providing a cost-effective avenue for resource extraction.
Military Metals’ commitment to sustainable practices and strategic exploration ensures a reliable supply of antimony, bolstering both energy independence and defense readiness.
What Comes Next for Antimony?
To meet antimony’s growing demand, a multi-faceted approach is essential:
- Investment in Domestic Mining: Expanding mining operations in countries like the U.S. and Canada can reduce reliance on imports and strengthen supply chain resilience.
- Technological Innovation: Developing alternative materials and recycling methods can alleviate pressure on antimony resources.
- International Cooperation: Collaborative efforts among nations can diversify supply chains and ensure equitable access to critical minerals.
Antimony is more than just a mineral; it is a linchpin for renewable energy and national security. As the world navigates the complexities of the clean energy transition and geopolitical tensions, ensuring a stable supply of this critical resource is paramount. The time to act is now, and antimony’s story is one of resilience, innovation, and opportunity.

The Strategic Case for Nature-Based Carbon Investments
Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.
1. Define the sourcing problem before choosing a project
Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.
This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.
CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.
2. Develop nature-based carbon investments around the actual supply chain
The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?
Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.
Suppose Moonbucks’ assessment identifies an opportunity to maintain shade trees and restore vegetation along exposed streambanks. The IPCC describes agroforestry as a way to store carbon in vegetation and soil, with potential benefits for erosion control and water quality.1 Moonbucks would need local advice on species, growing conditions and maintenance before deciding how these measures fit its sourcing plan.
The proposal now has a defined sourcing connection and a candidate intervention. The next steps are to test its effect on production, assess carbon eligibility and build the financial case.
3. Compare the proposal with other ways to protect supply
WBCSD’s Nature-based Solutions Blueprint recommends comparing nature-based options with other responses across their benefits and costs.2 For Moonbucks, that means evaluating the landscape proposal alongside drying improvements, storage controls and alternative sourcing arrangements.
The product’s natural-process designation matters. Moonbucks should examine the drying and dry-milling chain alongside land conditions. Its team would check storage practices, contamination risks and incoming-lot quality to see whether problems arise before or after the coffee leaves the farms.
The revised proposal might combine land stewardship with separate post-harvest controls. Each component needs its own purpose and budget. A sustainability label should not obscure which activity is expected to solve which problem.
The project develops as the evidence improves. Its scope should follow the diagnosis rather than preserve the first idea unchanged.
4. Establish what the carbon outcome could count toward
Moonbucks’ sustainability team now tests the proposed carbon case separately from the sourcing case. Is the objective a measurable change in Moonbucks’ value-chain emissions, verified credits for separate voluntary use, or distinct outcomes under carefully defined arrangements?
Scope 3 covers value-chain emissions. A purchasing relationship alone does not prove that a farm intervention can be included in Moonbucks’ inventory. The team needs an applicable accounting method, defensible boundaries and evidence supporting attribution.
SBTi’s FLAG Guidance (forest, land and agriculture), version 1.2, says purchased credits used as offsets cannot meet near-term FLAG or energy and industry targets. Eligible land-based removals are subject to accounting requirements.3 Moonbucks needs to test its proposal against those rules before including an outcome in its targets.
For Moonbucks’ Jimma proposal, maintaining existing trees and establishing new vegetation could involve different carbon questions. Specialists must examine the baseline and additionality, meaning what changes because the project proceeds. They must also assess measurement and the risk that stored carbon is lost. CCC’s MRV and additionality article introduces those tests.
Until that work is complete, Moonbucks should not budget an assumed Scope 3 reduction or credit-sale receipt. Direct emissions reductions remain the priority.
5. Build a financial case that survives weaker assumptions
Moonbucks’ finance team would now build a multi-year budget. UNEP’s State of Finance for Nature 2023 compares current finance with the investment needed to meet climate, biodiversity and land-restoration goals.4 The company would cost its proposed activities, farmer participation and ongoing monitoring. Verification, where required, is a separate expense. Maintenance and responsibility for replacing failed plantings must remain visible after the initial establishment budget ends.
Operational benefits need equally careful treatment. If fewer rejected lots reduce emergency purchasing, count that saving once. Do not add “supply resilience” as another financial benefit when it represents the same avoided cost.
Moonbucks should compare a base case with slower benefits, higher implementation costs and no carbon revenue. It should also distinguish production outcomes from quality and shipment outcomes. A single good harvest would not prove that the landscape intervention caused better delivery performance.
A project can remain worth funding even when its carbon case needs more work. That decision must rest on the operational evidence and the company’s objectives, without unsupported environmental claims.
6. Fund a pilot with a clear expansion decision
Moonbucks’ first approval would fund a bounded pilot, rather than commit the entire sourcing program. Before spending, Moonbucks would agree on participating farms, responsibilities and the evidence needed at review.
Its scorecard could track farmer participation, implementation costs and plant survival, alongside accepted coffee volumes and lot-quality results. Carbon measurements would follow the selected method. Farm-level traceability must connect the intervention to the actual sourcing relationship.
Suppose Moonbucks’ review later finds that storage changes explain most quality improvements, while the land measures need longer observation. Those findings would shape the next decision: expand the proven component, adjust the landscape work or pause further spending. They would not justify crediting all improvements to tree planting.
This gives nature-based carbon investments a practical place in a multi-year strategy. Funding increases as the evidence supports it, and the project can change direction before a larger commitment.

EU carbon credit claims after 27 September 2026
EU carbon credit claims changed on 27 September 2026, the day the Directive (EU) 2024/825 began to apply across the European Union. The change is narrow. It changes how a company can talk about the credits it buys. A product can no longer be called neutral on the strength of compensation alone; however, every specific, evidenced statement about what a company measured, reduced, and funded stays fully available.
