TERRA BALCANICA DISCOVERS SILVER AND ANTIMONY DOMINATED
EPITHERMAL MINERALIZATION AT BREZANI IN BOSNIA AND HERZEGOVINA
Vancouver, British Columbia – January 15th, 2025 – Terra Balcanica Resources Corp. (“Terra”
or the “Company”) (CSE:TERA; FRA:UB1) is pleased to announce the discovery of a ca. 20 m
wide zone of polymetallic mineralization intercepted during the Phase II drilling at the Brezani
target within its principal Viogor-Zanik project in eastern Bosnia and Herzegovina.
Highlights
• Continuation of drillhole BREDD002, which returned 88 m at 0.61 g/t AuEq from surface
(see company news release dated 24 th January 2023) has intercepted a substantial zone of
low/intermediate sulphidation epithermal mineralization;
• A ca. 10 m zone of continuous colloform/ginguro banded quartz-carbonate-sulphide
and sulphide cemented breccia (Figure 1) sits at the upper contact of a structural zone
where observed epithermal veining extends for a least 20 m;
• Epithermal mineralization projects ENE towards surface following a conductivity gradient
within a magnetic low and is interpreted to daylight in a topographic depression where As-
Bi-Sb-Te is anomalous in soil sample assays, offering a shallower drill target (Figure 2);
• Mineralization is polymetallic (Sb-Pb-Zn +/- Au-Ag) with evidence of several mineralizing
and fluid boiling events (Figure 3);
• Terminating at a depth of 674 m, the hole intercepted 118.4 m of chlorite-sericite altered
diorite porphyry;
• Terra has commenced a dense soil sampling program across the multi -domain Brezani
hydrothermal system to enhance the domains of gold skarn and surface expression of
epithermal mineralization (Figure 4);
• Samples from BREDD002 are currently being analysed and will be reported after the internal
QA/QC program has been completed and data deemed good quality.
Terra Balcanica CEO, Dr. Aleksandar Mišković, comments: “We are very excited with the
Brezani discovery which adds further value to this multi-domain, polymetallic target. The
significant mineralized intercept underlies the previously confirmed auriferous skarn starting from
surface and overlies a porphyry system which Terra has been targeting at Viogor -Zanik from the
very outset. We believe the potential of our discovery at Brezani , especially the macroscopically
identified antimony sulfides, is tremendous considering the shallowing of the epithermal
mineralization along a presumed fault to northeast and stratigraphic intercept below the boiling
horizon which will be targeted by our future drill programs. Collectively, this is a thrilling
development for Terra as we look forward to releasing the Brezani assay results shortly.”
The Company commenced redrilling BREDD002 from 215 m where 2022 drilling efforts ended
in a chlorite-sericite altered diorite porphyry, returning 0.26 g/t Au and reached a depth of 674 m.

The drillhole targeted a coincident magnetic and conductivity anomaly and intersected several
zones of calc- silicate alteration associated with phyllic and chlorite -sericite altered diorite
porphyries. A zone of epithermal mineralization within a large structure was intersected from
482.1 m downhole which marked the change into chlorite-sericite altered porphyritic diorites.

Photographs show the consistently well mineralized epithermal system which grades inwards from ginguro
banded chalcedonic quartz-rhodochrosite-calcite-sulphide on the vein margins to a base metal rich central
domain consisting of stibnite -sphalerite and minor galena breccia cement. Breccia is host to mineralized
clasts of banded veins indicating multiple episodes of mineralization and boiling (click here to view image).

Drillcore Observations
The zone of mineralization from 482.1 m consists of banded veins and sulphide cemented breccias
with characteristics of both low and intermediate sulphidation epithermal deposits. The upper vein
contact is sharp with minimal alteration progressing into the hornfels, whereas the vein footwall is
brecciated and hosts strong clay alteration. The margins of the vein host repeating bands of
chalcedonic quartz -rhodochrosite-calcite and sulphides /sulphosalts stibnite-pyrite-arsenopyrite-
sphalerite-galena-jamesonite. The centre of the structure is dominated by hydrothermal breccia
with a sulphide-quartz-carbonate cement. Clasts are banded vein fragments.
BREDD002 ended at 674 m depth after 118.4 m of chlorite -sericite altered diorite porphyry
intrusive. Sinuous quartz-pyrite-molybdenite veins, quartz-magnetite, anhydrite-carbonate, pyrite-
chlorite, and pyrrhotite -carbonate veining is present alongside disseminated pyrite-pyrrhotite.
Alteration is interpreted as strongly overprinted potassic, by chlorite -sericite. Local phyllic and
strong chlorite alteration is observed associated with carbonate -arsenopyrite-bismuthinite veins.
The intrusive texture is partially destroyed by the silica groundmass flooding and formation of
very fine-grained biotite giving the rock a reddish brown to grey- green colouration with chlorite
replacement and coarser grained muscovite mica. Hornblende phenocrysts have been replaced by
biotite and magnetite.

Drillhole BREDD002 is shown, with a tabular conductivity feature extending in cros section to the ENE
from the epithermal mineralized interval. Conductivity feature is interpreted as the continuation of the host
structure with increased conductivity due to sulphide and clay within the broken rock mass. It passes
through a break in the magnetics, which is further evidence of structural control (click here to view image).

Ongoing Exploration Program
Terra is undertaking a soil survey across the Brezani target on a 20 x 100 m grid (Figure 4). Sample
frequency is tighter in the E/W direction perpendicular to the gold skarn and epithermal corridor.
This will build on the initial 175 x 175 m , aqua regia ICP -MS soil sampling and delineate
geochemical domains. The interpreted surface expression of the newly discovered epithermal
mineralization will be covered, and results will assist in targeting prospective intervals along the
strike length of this structure for shallow, follow up drilling. Analysis is undertaken by an Olympus
Vanta unit and monitored by quality control using blanks and certified reference materials.
