Trojarova, Slovakia
Trojarova Property
Status: Exploration Adit with Resource
Military Metals Corp secured the coveted exploration license for the Trojarova Antimony-Gold Mine near Pezinok in Western Slovakia, just 15 km north of Bratislava. This license encompasses a historically rich resource and numerous historic mining operations within the ore district. Our strategic acquisition positions us to unlock significant value from these well-established assets, reinforcing our commitment to becoming a leading player in the antimony market.
Trojarova
HISTORY
The Trojarova deposit, after its initial discovery, underwent two phases of exploration: the first through drillholes and the second through the excavation of the Trojarova adit. The drillholes revealed high-quality antimony (Sb) mineralization, which was intended to be further accessed via the adit. Excavation of the adit began in the 1990s, funded by the state, until a German investor from Cologne joined the project. However, due to the investor’s failure to meet financial commitments during advanced stages of underground exploration, the project was halted. As a result, the adit did not reach the deposit’s richest ore sections.
Currently, the ore resource within the adit shows limited antimony content, with only two channel samples indicating Sb content above 2%. This suggests that no economically recoverable ore is presently accessible in the Trojarova adit. To access the rich ore, the adit would need to be extended by several hundred meters, presenting a significant opportunity for future development and extraction.
Adits and portal dating from the 1990s appear to be in fairly good condition.
Geology
Several historical resource estimates have been calculated for the Trojarova Antimony-Gold Mine using the Soviet-style classification of mineral deposits:
- 1989 Estimate: Based on the initial drilling program, this estimate defined blocks containing 1.665 million tonnes at 2.77% Sb and 0.81 g/t Au*.
- 1992 Estimate: Utilizing results from previous drilling and additional infill drilling, this resource was calculated at 0.831 million tonnes at 5.645% Sb and 0.676 g/t Au*.
- 1995 Estimate: The most recent historical resource estimation, based on data from the Trojarova adit underground exploration, provided a more conservative estimate of 0.415 million tonnes at 0.162% Sb and 1.148 g/t Au. This estimate is considered pessimistic as the exploration was halted prematurely, before reaching the drill-verified rich ore. The primary focus of this exploration project was on gold-arsenic ore rather than antimony-rich ore.
These historical resource estimates highlight the potential for significant antimony and gold reserves at Trojarova, pending further exploration and development to access the high-grade ore zones.

Tienesgrund, Slovakia
Tienesgrund Property
Status: Historical
The Split Nose Project, encompassing the Tienesgrund prospect, features two primary Sb-Au veins – northern and southern – which have been historically mined through several adits, including the Vysna adit (established in 1954). Historical reports estimate 162 tons of ore with an average antimony grade of 7.67%. Recent sampling has confirmed exceptional grades, with grab samples showing up to 38.10% Sb and 9.69 g/t Au.
This promising property, with its substantial quartz-stibnite veins and significant historical and recent high-grade samples, positions the Split Nose Project as a high-potential venture. The strategic location and robust geological data underscore the project’s potential to yield substantial returns, making it a key asset in our portfolio.
Tienesgrund
License
- Size: 13.38 km²
- Validity: 12.4.2022 to 12.4.2026
- Geology: Approximately 20 km long quartz-stibnite vein belt/ore district, with the license covering the eastern part.
- Vein Structure: Tectonically disrupted and segmented veins.
- Ore Formation: Stibnite ore forms lenses or ore-shoots within quartz veins, ranging from 10 m to 700 m long (e.g., Gabriela), with variable thickness from 5 cm to 8 m.
Commercial exploitation of the antimony veins at the Split Nose Project dates back to at least 1840, with demand historically driven by war conditions. The mines experienced various periods of activity and dormancy, notably reopening in the 1930s and producing around 1,000 tonnes of concentrate in 1932. The deposit is remarkably free of arsenic, unlike the nearby Cucma site, making it particularly valuable.
Production continued sporadically during the National Socialist period, with significant progress made in identifying additional minerals such as tungsten, with some samples grading 2.4% WO2. Despite subsequent prioritization of larger mines like Cucma and Dubrava, efforts in the 1950s aimed to reopen adits and firm up resources at the Split Nose Project.
Recent work, including a comprehensive Lidar survey, has confirmed the presence of high-grade antimony, with our sampling showing up to 38.10% Sb. This data underscores the significant potential of the Split Nose Project, positioning it as a high-potential venture with substantial antimony reserves, poised to meet the growing global demand for this critical mineral.

Geology
The tenement stretches for nearly 10 kilometers across a rich antimony system in the Slovak Ore Mountains in eastern Slovakia. As shown on the map below, the known antimony vein structures are marked in red, highlighting the extensive mineral potential of this region.
Various resources exist within the antimony veins and adits at the concession. The prime targets include the Margit, Rozabella, and Victor adits. Notably, the Rozabella adit boasts a historic resource estimate dating back to 1959.
These stated resources should be understood within the context of the stringent Soviet-era reporting rules and the strict economic definitions of the time. According to historical reports, the Rozabella adit contains 162 tons of ore with an average antimony grade of 7.67%. This promising figure, however, requires modern channel sampling and updating to reflect current economic cut-offs and antimony prices.
The Split Nose Project’s substantial geological potential positions it as a high-value asset ready to meet the growing global demand for antimony, making it a key strategic investment in the critical minerals sector.
Medvedi Potok, Slovakia
Bear Creek Property
Status: Historical Exploration
The exploration at Bear Creek, locally known as Medvedi Potok, began in response to a tin soil anomaly and was conducted from 1971 to 1981 by Geologický Prieskum, a state-owned enterprise.
During this period, extensive exploration activities were carried out, including the excavation of 36 trenches, drilling of 47 surface drill holes, and 82 underground wholesale drill holes. Additionally, two adits with a total length of 5,301 meters and one shaft with a depth of 10 meters were excavated.
The exploration results revealed 863,000 tonnes of ore with a 0.19% tin (Sn) grade. The tin-rich parts of the Medvedi Potok deposit are primarily found in veins, though these high-grade zones account for only 8% of the total reserves, equating to 71,000 tonnes.
The Full Metal Project, leveraging this historical data, aims to capitalize on the significant potential of the Medvedi Potok deposit, positioning it as a key asset in our portfolio of critical mineral resources.
Medvedi Potok
Geology
The geological long section of the Medvedi Potok deposit reveals significant potential, showcasing blocks of greisen and vein-style mineralization.
Based on historic exploration results, 863,000 tonnes of ore with a 0.19% tin (Sn) grade were calculated. While the tin-rich parts of the Medvedi Potok deposit are primarily found in veins, representing 8% of the total reserves (71,000 tonnes), the focus on antimony unlocks even greater value.
The Full Metal Project stands to benefit immensely from this antimony-rich geological setting. With substantial reserves and high-grade mineralization, this project is poised to capitalize on the rising demand for antimony, positioning it as a key player in the critical minerals market. The potential for significant antimony extraction, alongside the existing tin resources, makes the Full Metal Project a strategically valuable asset, ready to deliver substantial returns.
