Terra Balcanica, a junior Canadian explorer of critical metals, eyes untapped opportunities at Europe’s doorstep.

What do you get when you combine a millennia of mining history, two resource extraction-friendly European jurisdictions with clear paths to permitting mineral exploration concessions, a knowledgeable workforce, and a continent starved for critical metallic resources?

Add to that a world class metallogenic expertise and a plethora of innovative geochemical and geophysical techniques that helped define grassroot drill targets in less than a year, all of which proved to be mineralised. Welcome to Terra Balcanica Resources Corp. and its ~350km² polymetallic portfolio of the Western Balkan Peninsula.

Terra Balcanica is a junior Canadian explorer of precious and base metal resources in Europe’s front yard, where it has been advancing five exploration licenses in Bosnia and Serbia. Listed on both the Canadian Securities Exchange, and the Frankfurt Stock Exchange, the company has made strides since acquiring its flagship land package in eastern Bosnia in 2020.

Called the Viogor-Zanik Project, the 215km² aggregate of licences surrounds the operation Sase mine (Mineco Ltd.) with an annual production of 350,000 tonnes of Pb-Zn-Ag+/- Sb concentrate, and is centred upon a mining district mined as far back as the Roman times when it was known as Argentaria.

A multidisciplinary approach to target definition

In slightly over three years, Terra’s technical and field teams have mapped, sampled, surveyed, and drilled two out of three highly prospective target zones within the only Oligo-Miocene manifestation of the highly prolific Western Tethyan orogen in Bosnia and Herzegovina.

The belt, whose mapped southeastern extension reaches Afghanistan via the Balkans, Turkey, and Iran, features world class porphyry copper and epithermal gold-silver deposits (Sarcheshmeh, Sari Guni, Kişladag, Skouries, Olympias, Trepca), and terminates right at Terra Balcanica’s feet as the metalliferous Srebrenica Magmatic Complex.

Here, a meticulously systematic approach of layering dozens of data sets obtained by months of lithological and structural mapping, combined by those gained from airborne geophysics, satellite multispectral terrain surveys, and thousands of rock and soil chemical assays revealed two genetically distinct, yet equally attractive targets worth drill testing.

And drill, Terra did. Both the Cumavici and Brezani targets were tested to the tune of over 2,000m of diamond drilling, respectively, with attractive metal grades intercepted close to surface but the story does not stop with Bosnia.

In neighbouring Serbia and another mining heavyweight of Europe (e.g. Timok District), Terra Balcanica operates two exploration concessions in the historic Rashka district, once home to many a medieval Saxon miner employed by the Serbian kings of the epoch.

Here, the Ceovishte and Kaludra licences comprise a 130km² land portfolio rich in Zn-Pb-Ag-Au-Cu showings. Particularly interesting is the former, where Terra’s geologists have collected high-grade precious metal samples on-surface that overlay historical workings featuring highly enriched vein-hosted mineralisation. None of the Serbian targets have been drill tested to date, and remain Terra’s immediate focus for the 2024 Phase III campaign.

As only the second (foreign) mineral explorer in Bosnia, Terra Balcanica is poised to capitalise on regional early-mover opportunities, while remaining a nimble, agile, and cost-effective explorer of choice in SE Europe.

For many at Terra, discovering mineable resources needed by the world of tomorrow is not just a self-evident mission but an homage to the proud, century-long history of mining in Europe.

The art of discovery

Ours is a disciplined and creative team of mining professionals that has demonstrated an ability to make discoveries in places overlooked or abandoned by others, and to leverage these forgotten or neglected gems as incubators of the mining continuum, and value creators for our shareholders.

Whether it is systematically rehashing volumes of archived data sets, modelling newly acquired geophysical data, or rapidly ground-truthing the rugged vast expanse of the Western Balkan Peninsula aimed at targeting the ‘sweet spots’ – discovery is in our geological DNA. Our leadership group and technical team are fully vested and singularly committed to this goal.

The Čumavići target

Within the Viogor-Zanik Project of eastern Bosnia and Herzegovina lies the Čumavići target. This shallow, high-grade, polymetallic target area extends for over seven kilometres NW/SE through the project. Tens of mineralised showings which returned assay grades up to 128 g/t silver and 20% zinc are visible alongside historic mining works. Silver-zinc-manganese-antimony all show anomalism in soil geochemistry, coupled with linear magnetic low responses (indicative of possible host structures).

Terra has completed diamond drilling at two locations and discovered polymetallic veins and breccias returning assay grades up to 11m at 505 g/t silver equivalent (gold-silver-lead-antimony-zinc recalculated to the value of silver) in 2022 drillhole CMVDD004.

Individual drill core samples have returned values as high as 1,420 g/t silver over 1.7m and 31% combined lead and zinc over 90cm. Terra has only scratched the surface of the Čumavići story and is excited to continue drilling in 2024. As more mineralisation is discovered within the Čumavići corridor it is worth noting the proximity of Terras discovery to the operating Sase Mine, actively depleting their ore reserves.

The Brežani target

Just 11km to the southeast, within the Viogor-Zanik Project. lies the Brežani target. A greenfield discovery in 2021, Brežani presents a kilometre-scale mineralised hydrothermal system first identified as a large magnetic anomaly, coupled with over 700m strike length of elevated gold in soil. Drilling at the target has revealed not only that the gold on surface extends down to 88m (results from drillhole BREDD002) but is also host to strong epithermal mineralisation at depth.

The gold in drill core was consistent at 0.5 g/t, reaching up to 1.5 g/t for six metres. Brežani represents the only gold mineralised skarn (a calc-silicate rock) in Bosnia and Herzegovina and is set to grow with further drilling.

Recently discovered and extensive epithermal mineralisation encountered downhole shallows to the east-northeast, where a similar element assemblage of silver-arsenic-antimony is present within rock and soil samples from a topographic low, coupled with a magnetic low. This offers shallower drill targets for this prospective polymetallic mineralisation.

Prospective work at Ceovishte

Terra Balcanica also operates in neighbouring Serbia, where it holds 80km² of highly prospective land in the historic Raška mining district. The Ceovishte Project represents a previously overlooked high grade gold-copper target with surface rock chip assay results up to 64 g/t gold and 2% copper.

What is in store for 2024?

As a regional Balkans explorer, Terra Balcanica has proven capabilities of identifying prospective projects and discovery mineralisation. Being on the doorstep of Europe, and given the demand for critical metals such as lithium, Terra has identified a prospective area and is looking to move into the battery metal exploration space.

The western Balkan Li-B (lithium-boron) metallogenic zone spans for over 1,500km through Croatia, Bosnia and Herzegovina, Serbia, and Kosovo along its path to Turkey to the east. The Serbian portion of the zone hosts Rio Tinto’s Jadar Project, a sediment hosted lithium-boron deposit discovered in 2004 hosting indicated resources of 85.4Mt at 1.76% Li2O and 16.1% B2O3 with further inferred resources of 58.1Mt at 1.87% Li2O and 12.0% B2O3 as of 31 December 2021.

Terra Balcanica is excited to commence its lithium exploration journey in 2024 and add value to an already diversified portfolio of assets.

Sustainable mineral exploration practices

At Terra Balcanica, we emphasise responsible engagement with local communities, municipal governments, and key stakeholders. The company is committed to proactively implementing Good International Industry Practice (GIIP) and sustainable health, safety, and environmental management.

We are particularly proud of our workplace safety and environmental protection record that include safety trainings, baseline environmental surveys, and regular community initiatives. The goal is to have our employees return to their families safely while maintaining a minimal environmental footprint.
