TERRA BALCANICA OBTAINS EXPLORATION LICENCE IN BOSNIA-HERZEGOVINA
Vancouver, British Columbia – June 3rd, 2026 – Terra Balcanica Resources Corp. (“Terra ” or
the “Company”) (CSE:TERA; FRA:UB1; OTCQB:TEBAF) is pleased to announce that it has
secured a new mineral exploration licence (“Permit”) comprising the Viogor polymetallic project
in eastern Bosnia and Herzegovina.
The new mineral exploration permit for the “Pb-Zn-Cu and associated base and precious metals”
No. 05.04/310-366-3/26 was issued to Energetski minerali doo Banja Luka, a wholly owned Terra
subsidiary, by the Republic of Srpska Ministry of Energy and Mines on May 20th, 2026. The
exploration permit is valid for 3 years with the standard provisions for two 2 -year extensions
allowing for up to 7 years of continuous mineral exploration tenure.
The new permit area encapsulates the three targets defined by Terra’s diligent exploration activities
between 2020 and 2022, namely: the historically known Čumavići polymetallic corridor, the Kiseli
Potok Mo porphyry and the two Brežani discoveries. It encompasses 49.06 km2 and extends NW-
SE along the Alpine orogenic trend west and south of the town of Srebrenica (Figure 1.)
Figure 1. The Viogor mineral exploration licence encapsulates the three mineralized localities which will
be advanced over the next 7 years. The operating Mineco Ltd. Sase mine is strategically located 7 and 11
km away from Čumavići and Brežani, respectively (click here to view image).

Terra’s President and Chief Executive Officer, Dr. Aleksandar Mišković, P.Geo., remarked:
“Building on our discover ies of high-grade, silver-antimony-zinc-lead-gold mineralization at
Čumavići as well as an auriferous skarn and silver-antimony-zinc mineralization at Brežani, our
securing of the Viogor project is an important step in advancing Terra’s Bosnian assets. It allows
the Company to maintain drilled target areas for an additional seven years and as such to become
one of the very few suppliers of critical metals , notably antimony, for the neighboring European
markets. Removing tenure uncertainty paves way for unhindered push towards a preliminary
resource estimate next year . Not only is the award of Viogor fundamental for our success but it
also illustrates the ease of doing business in Republic of Srpska, Bosnia and Herzegovina while
highlighting the expertise of our management team when it comes to holding onto key assets.”
Viogor Project
The Permit p roject covers 49.06 square kilometres of historic Srebrenica mining district (i.e.
Srebrenica Magmatic Complex ; see below ) within one active exploration licence. It includes a
series of silver and base metal targets interpreted as intermediate sulfidation epithermal veins and
lies approximately 80 kilometres east-northeast of the Dundee Precious Metals’ Vareš mine that
hosts Indicated Mineral Resources of 18.3 Mt at 168 g/t Ag, 1.3 g/t Au, 4.6% Zn, 2.9% Pb, 0.4%
Cu and 30% BaSO4 and Inferred Mineral Resources of 2.8 Mt at 75 g/t Ag, 0.5 g/t Au, 2.4% Zn,
1.6% Pb, 0.2% Cu and 13% BaSO 4, a deposit comparable in grade and metal composition to the
two targets at Viogor.
Terra’s exploration licence is also located adjacent to the Mineco Ltd. Gross (Sase) Mine which
produces approximately 330 kt of lead -zinc-silver-gold concentrate per year (Figure 1;
https://www.minecogroup.com/gross). This facility hosts a crushing and flotation circuits to
process the ore which is genetically identical to the mineralized horizons drilled by Terra and thus
offers a strategic advantage during further project development.
Regional and Project Geology
The Srebrenica Magmatic Complex (SMC) is the 30- million-year-old, western member of the
Podrinje Metallogenic District which includes the Serbian Cer and Boranja mining districts,
collectively the northwesternmost extensions of the Serbo -Macedonian Metallogenic Province
(SMMP) of the Western T ethyan Metallogenic Belt. The SMMP mainly hosts deposits of
Paleogene to Neogene age. The Srebrenica district is hosted by Oligo- Miocene, intermediate to
mafic subvolcanic rocks emplaced into Paleozoic slates and covered by Neogene felsic
pyroclastics.
The district has been known to host two types of mineralization: (i) cassiterite -bearing, greisen
mineralization related to quartz -tourmaline-muscovite facies, and (ii) Pb –Zn–Fe bearing
hydrothermal veins with variable concentrations of Ag, Sn and Sb. As such, the Srebrenica district
shares many mineralogical similarities to those of the Andean Ag –Sn belt, Germany’s Freiberg-
Erzgebirge district, the Lavrion deposit in Greece, and the Baia Mare Metallogenic District of East
Carpathians, in Romania. The Srebr enica mineralization contains a comparable mineral
assemblage to that of the San José Ag –Sn deposit, Oruro, Bolivia (cassiterite, stannite, pyrite,
chalcopyrite, argentian tetrahedrite, galena and sphalerite).

The ore mineralization in Srebrenica is related to a syn -volcanic ring- radial fractures where
hydrothermal ore veins are concentrated within four main systems of brecciated fractures: (i) the
NE ore zone (Sase/Gross mine), (ii) the NW ore zone (Čumavići), (iii) the northern ore zone
(Vitlovac), and (iv) the central ore system (Guber, Olovine). The origin of ore mineralization is
genetically associated with a concealed plutonic body of S -type granitoid composition shallowly
emplaced beneath the south-central part of the district.
Extensive greisen bodies are particularly well developed and composed of quartz, tourmaline and
muscovite are found along the contact between the micro -granodiorites and Paleozoic slates.
Tourmaline occurs as needle shaped, columnar and radiating aggregate s. Greisens tend to be
associated with endoskarns and indicate a proximal intrusive body with upper aureoles sealed shut
to prevent fluids escaping. The Pb-Zn sulfides, accompanied by siderite, marcasite, sulfosalts and
Ag sulfides are the dominant hydrothermal ore minerals, developed in the central part of the
district, while in the peripheral parts there is mineralization associated with low -temperature
epithermal veins (Sb, locally W, and Hg). The chief targets zones at Viogor presently include:
• The Čumavići corridor comprises a series of shallow, high grade, intermediate sulphidation
epithermal Ag-Au-Pb-Zn-Sb vein- hosted targets with over 7.2 km of strike -length and
hosted by clastic and crystalline tuffs and pyroclastic breccias. The host volcanics have been
crosscut by NW-SE trending structures and are part of the larger SMC magmatic-hydrothermal
system. High-grade epithermal m ineralization is silver and antimony dominant with further
gold-lead-zinc tenure. Terra’s drilling has confirmed three polymetallic systems so far: Joševa,
Čumavići Crest, and the flagship vein system at Čumavići Ridge. The Cumurnica and Kazani
targets remain to be drill tested. Thus far, the average grade of polymetallic mineralization at
the flagship Čumavići Ridge system, which has seen over 28 drill holes along 180 m of strike
length, averages 485 g/t Ag Eq. over 4.0 m (March 2026 commodity prices). Mineralogically,
the ore is characterized by sphalerite-stibnite-galena and further silver-rich sulphosalts that are
associated with quartz and calcite veining and breccia cement. Epithermal mineralization
occupies faults which crop out at surface as distinctive topographic lows, coinciding with
magnetic lows and often with sulfides visible within fault gouge.
• Brežani hosts components of a large , multidomain, magmatic -hydrothermal system
discovered by airborne TEM-magnetic and geochemical surveys. It comprises a 650 m by 400
m large, retrograde, chlorite overprinted, Au -bearing skarn upon a shallowing, base metal
rich, structurally controlled, intermediate sulfidation epithermal ore zone at depth. The
BRE23001 through 23004 diamond drill holes were located within the Au-in-soil anomaly and
were intended to assess lithological variability and grade of the Au skarn along strike.
Additionally, the drillholes tested the resistive volume above an abrupt change into a central
magnetic low shell within the general >95 th percentile magnetic high anomaly to verify the
lateral extent of 0.61 g/t Au Eq. drilled in the central BREDD002.
This particular discovery hole further intercepted ca. 20 m of fault-breccia hosted Ag-Sb-Zn
mineralization at 480 m of depth grading upwards of 436 g/t Ag Eq. This intercept is
coincident with a 1.2 km long EM conductor shallowing towards northeast and eventually

surfacing at the topographic high of Brežani which was imaged during the 2021 TEM study.
The mineralogical textures form the initial intercept pierced through the ore zone suggest a
stratigraphic level that is apparently below the so-called “boiling zone” thus offering potential
upside should one be intercepted up dip. The lateral extent of the 17-degree dipping conductor
interpreted as the Sb-Ag-Zn mineralization is 1.2 km in length, up to 600 m in width and 20 m
thick offers potential for a large tonnage ore body.
Shares for Debt
The Company has further agreed to settle outstanding debt s in the amount of C$1 00,000 (the
“Debt”) owing to two arm’s length creditors by issuing an aggregate of 1,666,666 common shares
in the capital of the Company (the “Common Shares”) at a price of C$0.06 per Common Share
(the “Shares for Debt Transaction”). The Board of Directors has determined it is in the best
interests of the Company to settle the outstanding Debt by the issuance of the Common Shares in
order to preserve the Company’s cash for ongoing operations.
Closing of the Shares for Debt Transaction is subject to customary closing conditions, and the
Company intends to close as soon as practicable. The Common Shares to be issued pursuant to the
Shares for Debt Transaction will be subject to a hold period of f our (4) months and one (1) day
from the date of issuance in accordance with applicable securities laws.
