TERRA BALCANICA DRILLS 102 G/T AG EQ OVER 2.55 M AT CUMAVICI RIDGE
AND EXTEND MINERALIZED FOOTPRINT IN BOSNIA AND HERZEGOVINA
Vancouver, British Columbia – January 15th, 2025 – Terra Balcanica Resources Corp. (“Terra”
or the “Company”) (CSE:TERA; FRA:UB1; OTC:TEBAF) is pleased to announce initial high-
grade assay results from the Phase III drill campaign at Cumavici Ridge epithermal vein zone
within its principal Viogor-Zanik project in Bosnia and Herzegovina.
Highlights
• Drillhole CMV25001 intersected 102g/t Ag Eq. over 2.55 m within a broader zone of 64 g/t
Ag Eq. over 4.7 m from 66m (Table 1) and including 0.4 m wide epithermal mineralized
zone with 453 g/t Ag Eq. over 0.4 m;
• Strike length extended to 95m from CMV23004 which returned 1168 g/t AgEq over 1.35
m. Further drilling at Cumavici returned highlights of:
• 505 g/t AgEq over 11 m (CMVDD004)
• 824.2g/t AgEq over 4m (CMVDD001)
• 284g/t AgEq over 10m (CMVDD005 ; see company news releases dated 8 th September
22nd October 2022 as well as 2nd and 27th February 2023);
• The mineralization remains open northwest and down-dip to the southwest;
• Additional Phase III assays from diamond drillholes at Cumavici Ridge and Brezani targets
will be released imminently.
Terra Balcanica CEO, Dr. Aleksandar Mišković, commented: “We are very pleased to have
extended the footprint at the high -grade Chumavichi Ridge system by continuing to intercept the
mineralized horizon. Again, the epithermal, fault hosted mineralization was intercepted shallowly
highlighting the potential of this SW -dipping structure, a high -grade, close-to-surface silver and
base metal rich target. Our work testing the along -strike and down -dip extent of the Cumavici
mineralization continues with more assays which Terra will report soon.”

Table 1. Assay results from drillhole CMV25001 with the interval lengths reported as drilled lengths, not
true widths. Silver equivalents (“AgEq”) are based on assumed metal prices of US$4,500/oz for gold (Au),
US$80/oz for silver (Ag), US$1.40/lb for zinc (Zn), US$20/lb for antimony (Sb) and US$0.9/lb for lead
(Pb). Assumed metal recoveries of 90% Au, 93% Ag, 95% Sb, 94% Pb and Zn are based on published
metallurgical tests on analogous intermediate sulphidation epithermal vein deposits.

Drillcore Observations
The zone of mineralization from 64 m to 73 m (Figure 1) is characterized by a fault -hosted
hydrothermal breccia. The structure crosscuts a package of andesites and volcanic tuffs. This has

created breccia and fault gouge is present at the margins of the structure which hosts the
mineralisation. A 0.4m interval from 69.1m presents as massive sulphides of sphalerite-galena-
stibnite-pyrite with sulphide stringers extending into the clay altered volcanics in the hanging and
footwall of the host structure. Drilling has importantly confirmed further continuation of the
Cumavici mineralisation, which was confirmed as present on Cumavici Crest over 500 m NW.

Geology of Cumavici
The Cumavici license is dominated by volcanic rocks (tuffs and pyroclastic breccias) which have
been crosscut by generally NW-SE trending structures and are part of a large epithermal mineral
system. Mineralization is silver and antimony dominant with further gold-lead-zinc (Figure 2).

The Phase III drilling has confirmed 3 polymetallic systems so far exploration at Cumavici. Joseva,
Cumavici Crest, and the flagship vein system at Cumavici Ridge. Mineralisation is characterised
by sphalerite-stibnite-galena and further sulphosalts minerals which are associated with quartz and
calcite veining and breccia cement. The mineralisation occupies faults which crop out at surface
as distinctive topographic lows, coinciding with magnetic lows and often with mineralisation
visible within fault gouge.
QA/QC
Half PQ3 core samples were delivered to ALS Bor, Serbia for sample preparation and analysis at
the ALS laboratory Loughrea, Ireland an ISO/IEC 17025:2017 certified testing laboratory. Sample
preparation PREP-31BY method was used on all core samples. This involves crushing to 70% less
than 2 mm, rotary split 1kg and pulverizing the split to greater than 85% passing 75 microns. Gold
was assayed by 30g fire assay with ICP-AES finish (Au-ICP21). Analyses of silver and base metals
were completed by highly oxidising digestion with HNO3, KClO3 and HBr (ASY -ORE) and the
final solution in dilute aqua regia is determined by ICP -AES (ME-ICPORE). Control samples,
comprising certified reference materials (CDN -ME-1811), and blanks were inserted at a r ate of
9% and investigated as part of the company’s quality assurance and quality control program.
