Military Metals’ Maiden Trojárová Resource Highlights EU Antimony Supply Gap

Europe’s drive to reduce reliance on external supply chains for strategic minerals is colliding with a persistent reality: domestic antimony production remains extremely limited. Against that backdrop, Military Metals has published a maiden inferred resource estimate for its Trojárová antimony-gold project in western Slovakia—an early but meaningful benchmark for an EU-based critical-material asset.

Maiden inferred resource sets the baseline

The company outlined a total inferred resource of 6.5 million tonnes grading 1.02% antimony and 1.06 g/t gold. On that basis, the deposit is estimated to contain approximately 67,000 tonnes of contained antimony and 222,000 ounces of gold.

Antimony is widely used in defence applications, flame retardants and advanced industrial systems, while gold adds potential economic value and diversification to project revenues. In an EU context where comparable domestic supply is scarce, the scale of Trojárová under modern reporting standards is positioned as strategically relevant from both industrial and security perspectives.

Built from drilling plus historical underground sampling

The estimate is supported by 53 drill holes totaling 7,167 metres, alongside historical underground sampling data. Military Metals says the resource has been prepared in line with internationally accepted reporting standards.

Because the material is classified as inferred, it is not yet fully bankable. Still, management characterises the model as providing the first coherent geological framework for the project and demonstrating continuity of mineralisation—key steps in converting legacy exploration information into a structured resource base.

Resource release timed with EU critical minerals policy

The announcement comes as the European Union accelerates implementation of its Critical Raw Materials Act, designed to strengthen domestic supply of strategically important minerals. Antimony has drawn heightened attention due to its importance in defence manufacturing, heavy reliance on non-European supply sources, and limited recycling or substitution options.

Trojárová is therefore being framed as a potentially significant EU-based antimony asset—particularly notable given how few comparable deposits have been reported under current standards.

Preliminary dual-metal economics aim to improve resilience

To support project viability, Military Metals applied long-term indicative assumptions of around $29,000 per tonne for antimony and approximately $3,000 per ounce for gold. It also assumed estimated metallurgical recoveries of about 85% for both metals.

These figures are described as preliminary, but they point to a dual-revenue structure that could help offset some of antimony’s inherent price volatility—an important consideration when investors weigh whether upstream development can translate into durable value.

Exploration upside remains open along strike

The company says the resource remains open along strike, particularly toward the northern extension of the deposit. That suggests potential expansion through additional drilling and could help increase total resource size while improving geological confidence.

Further work could also support advancement toward a preliminary economic assessment (PEA), moving Trojárová beyond an initial geological foundation toward more decision-grade evaluation.

Strategic value depends on downstream constraints

For investors and policymakers alike, Trojárová’s significance extends beyond near-term production timelines: it represents a potential building block in efforts to improve industrial supply security for critical minerals within Europe.

However, major challenges remain. The text highlights limited EU-based antimony processing capacity, complex permitting and financing requirements, and the need for downstream integration into refining chains. Without addressing those constraints, developing upstream resources alone may not be sufficient to resolve Europe’s broader supply dependency problem.
