FOČA, Bosnia and Herzegovina : Most of the mining world is obsessed with the same five jurisdictions. They are fighting over the same tired scraps in the Andes or the Australian Outback, paying premiums for projects that have been picked over for decades.
But there is an uncomfortable truth that many Western majors are finally starting to acknowledge: the next generation of tier-one polymetallic assets won’t come from the usual suspects. They will come from the Dinaride metallogenic zone.
Leviathan Metals is betting heavily on this reality. The company recently announced the grant of the Tjemenik exploration license, a move that effectively solidifies its dominance in one of the most promising mineral frontiers in Eastern Europe. With this expansion, the Foča Project now encompasses 100.7 square kilometers across three contiguous licenses.
This isn’t just about adding land for the sake of a press release. It’s about controlling the Vrela-Kremin trend, a geological corridor that is proving to be a nightmare for skeptics and a goldmine, literally and figuratively: for those tracking base metal supply gaps.
The Tjemenik expansion: More than just a footprint
The grant of the Tjemenik license is the final piece of a jurisdictional puzzle. By securing this ground, Leviathan now controls the interpreted northern extension of the Vrela-Kremin trend. For the uninitiated, this trend is a high-conviction target for silver and base metal deposits, specifically Mississippi Valley Type (MVT) or SEDEX (Sedimentary Exhalative) origin.
The strategic calculus here isn’t subtle: in a world where we are staring down a massive copper deficit in 2026, securing high-grade polymetallic ground is the only way to insulate a portfolio against the coming supply crunch.
Historical data meets modern geophysics
The Foča Project isn’t a “shot in the dark” greenfield play. It sits on a foundation of Yugoslav-era data that would be impossible to replicate today for less than tens of millions of dollars. In 1967, state-sponsored drilling at the Vrela Prospect hit three diamond drill holes that recorded an average mineralized thickness of 15 meters.
The grade? 13.25% combined lead and zinc.
Per facility. That’s not a typo.
For decades, this data sat in archives while the region navigated geopolitical shifts. Now, Leviathan is applying modern tech to these legacy “hits.” Recent induced polarization (IP) and electrical resistivity surveys have identified a chargeable feature roughly 75 to 100 meters wide. This isn’t a localized blip; it coincides with a mapped fault system extending over 2 kilometers.
The interpretation is clear: this fault represents the primary conduit for mineralization. The historical drill holes likely only scratched the surface of a much larger system.
Vrela: The immediate catalyst
Leviathan isn’t waiting for the 2026 season to start moving dirt. A phase of shallow mechanical trenching is currently underway at the Vrela Prospect. The goal is simple: confirm the surface expression of the IP anomalies and define targets for a 2026 diamond drilling campaign.
The numbers coming out of the field are brutal: in a good way. Recent rock chip sampling returned:
- 347 g/t silver
- 10.1% lead
- 40% zinc
These results didn’t come from a single lucky rock. They were gathered from field exposures and mineralized float across the prospect. Furthermore, soil sampling completed in late 2024 defined a coherent lead-zinc anomaly extending 2 kilometers northeast of the 1967 drill sites.
The mineralization isn’t just there; it’s expanding.
The Barice Prospect: The copper kicker
While Vrela handles the lead-zinc-silver narrative, the Barice Prospect is emerging as the project’s copper engine. Massive sulfide mineralization at Barice has returned rock chip assays as high as 4.48% copper, paired with 110 g/t silver and significant lead-zinc hits.
This polymetallic mix is crucial. As we’ve noted in our analysis of why M&A won’t solve the copper supply crisis, the industry cannot simply merge its way out of a shortage. We need new discoveries. Barice represents the kind of high-grade, multi-commodity potential that makes a project resilient to price swings in any single metal.
Jurisdiction: The Adriatic factor
The biggest hurdle for any Balkan project is “perceived risk.” However, the success of Adriatic Metals’ Vareš project, located just 100 kilometers to the north, has fundamentally changed the narrative. Vareš proved that high-grade polymetallic mines can be permitted, financed, and built in Bosnia and Herzegovina to modern ESG standards.
Leviathan is operating in the same Central Dinaride metallogenic zone. The geological similarities are striking, but the valuation gap between a developer like Adriatic and an explorer like Leviathan is where the opportunity lies for the disciplined investor.
The Bosnian government has shown a renewed appetite for mining investment, recognizing that its mineral wealth is a fast track to economic modernization.

2026 Outlook: The drill bit will decide
As we move into 2026, the Foča Project is entering its most critical phase. The “low-hanging fruit” of geophysics and soil sampling has been picked. Now comes the truth machine: the diamond drill rig.
The 2026 program will likely focus on three fronts:
- Vrela Depth Extension: Testing the 15-meter thick historical horizon at depth and along strike.
- IP Target Testing: Drilling the 2km-long chargeable conduit identified in recent surveys.
- Barice Sulfide Search: Locating the source of the high-grade copper chips found on surface.
Investors should watch for the integration of these results into a maiden resource estimate toward the end of the year. In a market where central bank gold reserves are hitting record highs and silver is riding the coattails of the energy transition, a high-grade silver-base metal project in Europe’s backyard is a rare bird.
The Bottom Line
Leviathan Metals is doing the work that the majors are too bureaucratic to handle. They are moving fast in a jurisdiction that rewards first-movers. The expansion of the Foča Project via the Tjemenik license isn’t a minor update; it is a land grab in a region that is about to become very crowded.
The technicals are there: 40% zinc, 4% copper, and silver grades that would make a Mexican explorer blush. The historical validation is there. The jurisdictional blueprint is there.
But here is the kicker: 2026 is the year the supply-demand imbalance in base metals stops being a projection and starts being a crisis. Companies that have used the last 24 months to build a dominant land position in high-grade districts will be the ones holding the cards.
Leviathan is currently holding a very strong hand.
