Military Metals Corp has suffered a potentially devastating setback at its flagship European asset after Slovakia’s Ministry of the Environment revoked the exploration licence for the Trojarova antimony-gold project near Bratislava without providing clear justification — a decision that sent the company’s shares sliding by up to 60% to a 52-week low on Friday.
The revocation is particularly striking given its timing and context. The ministry’s decision came just weeks after Military Metals filed the NI 43-101 technical report supporting a maiden inferred mineral resource estimate of 6.5 million tonnes grading 1.02% antimony and 1.06 grams per tonne gold, containing 67,000 tonnes of antimony and 222,000 ounces of gold. The MRE had been published on 8 April, with analyst Christopher Ecclestone of Hallgarten & Company highlighting its strategic importance for Europe’s critical minerals needs and the value of the project’s existing Soviet-era underground infrastructure. The licence revocation also came despite Trojarova having been listed in Slovakia’s own National Program for the Exploration of Critical Mineral Raw Materials.
Military Metals has announced it will appeal the decision within the 15-day statutory window and pursue all available legal options. The company described the revocation as inconsistent with Europe’s stated goals for secure critical mineral supply chains — a pointed observation given that antimony has been subject to Chinese export controls since September 2024, causing prices to double and exposing Western defence and semiconductor supply chains to acute vulnerability.
Trojarova’s strategic case rests on antimony’s role in hardening lead for ammunition, flame retardants in military equipment, infrared detectors, semiconductors and next-generation batteries. The project’s location near Bratislava and its extensive historical workings were seen as advantages that could accelerate development and reduce costs relative to greenfield projects.
While the legal battle proceeds in Slovakia, Military Metals is continuing exploration at its North American assets — the Last Chance antimony property in Nye County, Nevada, with a history of production, and the West Gore antimony-gold property in Nova Scotia, which produced during the First World War.
