Terra Balcanica Intersects 0.61 G/T GOLD Equivalent over 88.0 M from Surface at Brezani Discovery, Viogor-Zanik IN Bosnia-Herzegovina
TERRA BALCANICA INTERSECTS 0.61 G/T GOLD EQUIVALENT OVER 88.0 M FROM
SURFACE AT BREZANI DISCOVERY, VIOGOR-ZANIK IN BOSNIA-HERZEGOVINA
Vancouver, British Columbia – January 24th 2023 – Terra Balcanica Resources Corp. (“Terra”
or the “ Company”) (CSE:TERA; FRA: UB1) is pleased to announce the discovery of a gold
bearing system at Brezani within its 90% owned Viogor-Zanik project, Bosnia and Herzegovina.
Highlights
• Another Viogor-Zanik discovery: the Brezani target maiden drillholes intercepted 0.61
g/t AuEq over 88.0 m (BREDD002) and 0.58 g/t AuEq over 28.6 m (BREDD001); both
drillholes encountered gold mineralization from surface confirming the extension of the 32
m at 0.54 g/t AuEq interval detected by trenching 65 m southeast of the drillhole collars
(see Company news release from August 17th, 2022);
• Expanding district-scale polymetallic footprint: Viogor-Zanik now features 3 styles of
mineralization with 7 metals; the Brezani gold bearing system sits 12 km southeast of the
high-grade, polymetallic Cumavici discovery (see Figure 1) which intercepted:
o 824.2 g/t AgEq. over 4.0 m including 1634.4 g/t AgEq. over 2.0 m
o 816.1 g/t AgEq. over 2.0 m
o 465.5 g/t AgEq . over 8.7 m including 1196.6 g/t AgEq. over 2.0 m (see Company
news releases from September 8th and October 22nd, 2022);
• Open at depth with favorable lithologies : BREDD002 terminated in elevated gold
mineralization at 215 m depth; the Company interprets the elevated gold at the end of
the drillhole to be associated with another mineralized zone and silica -chlorite-sericite
altered intrusive lithologies downhole highlight the potential for porphyry style
mineralization which will require further drill testing (see Figure 3);
• Exploration upside: gold-bearing target at Brezani coincides with a resistive volume of
rock above a large conductivity anomaly (> 600 m wide , > 60 mS/m ) interpreted to
represent porphyry style mineralization (see Figure 3), which remains untested.
Terra Balcanica President and CEO, Dr. Aleksandar (Alex) Miskovic, commented: “We are
extremely excited about the Brezani gold discovery located over 12 km southeast of the high-grade,
polymetallic discovery made by Terra Balcanica at the Cumavici target last year. The Viogor -
Zanik project is clearly underexplored as we have identified a number of quality exploration
targets through our detailed targeting in 2021 and we have now confirmed three different styles
of magmatic-hydrothermal mineralization. The intercepted metasomatized hornfels suggests that
we are in the upper part of a large retrograde skarn-porphyry system at Brezani with the gold
mineralization encountered from surface and a significant potential for either a deeper porphyry
or a sulphide rich Cu- Au proximal skarn mineralization . The spatial coincidence of precious
metals with a plus 1.2 km wide magnetic anomaly and the presence of a strong electric conductor
at 400 m depth detected via airborne geophysics gives us confidence that we have a large potential
mineralized system on our hands. We look forward to more assays from the 2022 program which
will be released over the coming weeks.”

Interval lengths reported are drilled lengths and not true widths. AuEq calculation assumes metal prices of
US$1,900/oz for gold (Au), US$24.00/oz for silver (Ag), US$4.00/lb for copper (Cu) and US$1.65/lb for
zinc (Zn). Metallurgical recoveries of 95% have been adopted based on metallurgical testwork by Dundee
Precious Metals Inc. (TSX:DPM) on their Coka Rakita Au skarn in Serbia (see Note 1 below). BREDD001
was terminated early at 28.6 meters due to increased levels of core loss.

drill target areas and their associated styles of mineralization: (i) the epithermal Cumavici corridor, (ii)
the Olovine porphyry target and (iii) the southwesterly Brezani skarn/porphyry system is located
approximately 12 km SE of the Cumavici Ridge discovery drillholes. (Click here to view image)
Brezani is located 8.4 km south of the Mineco Ltd.Sase Mine which produces approximately 330
kt of lead-zinc-silver-gold concentrate per year (Figure 1). Brezani hosts components of a large
magmatic-hydrothermal system discovered by geophysical and geochemical surveys (Figure 2).
Drillhole BREDD001 was terminated at 28.6 m depth due increased levels of core loss. The core
returned 28.6 m at 0.58 g/t AuEq from surface. The lithologies intercepted were strongly oxidized
diorites and hydrothermal breccias, ending in a calc -silicate hornfels. Au contents of up to 1.9 m
at 2.46 g/t Au are observed in hydrothermal breccias of dioritic intrusive rocks, apopheses of an
underlying pre/inter-mineral intrusion.
Figure 2. Geological map highlighting the 1.2km wide, 95th percentile magnetic anomaly at the Brezani
target. The strongest magnetic response remains untested at depth, however correlates to Au in surface
trenches, quartz vein bearing sericitized diorites and calc-silicate altered hornfels with elevated
concentrations of proximal pathfinder elements (Bi-Te) from soil geochemistry. Distal zonation sees strong
argillic alteration and a Zn-Mn geochemical halo. (Click here to view image)
Drillhole BREDD00 2 was d esigned as a subsequent hole to BREDD001 to test the resistive
hanging wall existing below the exposed calc -silicate hornfels. The drillhole c ollar was centered
on an 850 m wide Au in soil anomaly and located 65 m NW from the previously completed
exploratory trenches that yielded 32 m at 0.54 g/t AuEq (See Company’s news release dated
August 17th, 2022). The mineralized interval reporting 88.0 m at 0.61 g/t AuEq from surface
includes 7 m of dilution from a late, post-mineralization diorite dyke.
Figure 3. Conductivity profile of the Brezani target with >95th percentile magnetic anomaly. BREDD002
tests the resistive volume above an abrupt change into coincident high magnetic and elevated electrical
conductivity response below 300 m depth which culminates at >60 mS/m at 450 m of depth. Dashed line
represents distance from the end of BREDD002 to the top of conductor. (Click here to view image)
The sulphides encountered at Brezani are characterised by both disseminated and intervals of semi-
massive sphalerite-chalcopyrite (Figure 4). Pyrrhotite is the dominant iron sulphide, with pyrite
uncommon. The gold is controlled by lithology and associated with skarns, calc-silicate hornfels
and specific intrusive phases. Quartz veins host pyrrhotite, sphalerite, chalcopyrite and
molybdenite. A less reactive hornfels is present between 87.2 and 199 m depth but silicified diorite
reappears between 214 and 215 m depth where t he drillhole ended in Au mineralization
returning 0.26 g/t Au.
Intermediate sulphidation veins were observed at 156 m and 168 m downhole returning 1.0 m at
0.39 g/t Au and 1.0 m at 0.34 g/t Au, 12.1 g/t Ag, respectively. The presence of these veins
confirms another mineralization style within the broad porphyry (Cu) model. Mineralogy is varied
with pyrrhotite, pyrite, sphalerite, galena, arsenopyrite and bismuthinite present within fault
hosted, quartz-carbonate veins (Figure 5).

Table 2. Collar location and core recoveries for diamond drillhole BREDD001 and BREDD002 (UTM;
WGS84). BREDD001 drillhole experienced a cumulative core loss of 2.0 m between 14.9-15.4 m, 16.3-16.9
m, 19.6-20.1 m, and 25.8-26.2 m, while BREDD002 experienced core loss of 0.8 m between 24.0-24.8m.
The Brezani target bears lithological similarities with the Rogozna Project operated by Zlatna Reka
Resources located 150 km SW within the Oligo -Miocene Tethyan belt in neighbouring Serbia.
The Rogozna Au-Cu skarn deposit has a 2021 JORC compliant inferred mineral resource of 64 Mt
grading 0.7 g/t Au and 0.2% Cu (2.15 Moz Au total), c alculated using multiple indicator kriging
on 154 drillholes, totalling 90,278 drill metres ( https://ibaera.com/rogozna-2-15moz-au-eq-
maiden-resource-estimate/).
Further Drilling: The coincident strong magnetic and conductivity anomalies (> 60 mS/m) below
the resistive surface shell at Brezani remains untested and presents a promising target for increased,
interconnected sulphide content characteristic of mineralized porphyry shells (Figure 3), which
will be the Company’s priority during the 2023 drilling campaign. Follow up will be undertaken
from other locations within the Au -in-soil anomaly to assess lithological variability and grade of
the Au skarn along strike. Additional drilling will test Au anomalous rock chips within argillically
altered volcanics and hydrothermal breccias thus offering a chance for testing multiple styles of
mineralization within a broad porphyry model.
