Terra Balcanica Resources Corp. announced the completion of the 1st stage of its 2,100 m Phase III drilling program at the Brezani and Chumavichi targets within its polymetallic Viogor-Zanik project in Bosnia and Herzegovina. Approximately 1,200 m of oriented, diamond core drilling was conducted at the Brezani andChumavichi targets within Terra's 168 km2 project in eastern Bosnia; Drillholes BRE25001 and BRE25001A, positioned 72 m NE of the discovery hole BREDD002 which returned 19.6 m at 436 g/t AgEq, have both intercepted a ca.

50-60 m interval of retrograde altered skarn, the host of the previously reported 0.61g/t AuEq over 88m, as well as several structural zones hosting intermediate sulphidation epithermal mineralization; Drillholes CMV25001 through 25004 have intercepted multiple zones of shallow, massive sulphide and quartz-sulphide, vein-hosted mineralization in the hanging and footwall of the SW dipping Chumavichi structure, all above 80 m depth; Epithermal mineralization encountered at both targets is polymetallic (Ag-Sb-Zn-Pb-Au) as confirmed by sulphide observations and pXRF. Key mineralized intervals have been sequentially sampled and are pending assay completion; The complete lithogeochemical assays will be reported after the laboratory data is received in its entirety. The 2025 drilling program follows up on high grade, polymetallic mineralizations which Terra has previously discovered, namely at Brezani and ChUMavichi targets, Viogor-ZanIK Project, Eastern Bosnia.

Phase III aims to increase geological knowledge at both localities which have provided outstanding drilling results to date. The Brezani discovery, is a two-part story. Initial drilling revealed 88m from surface of 0.61g/t AgEq (0.60 g/t Au) within a retrograde altered skarn and hornfels package, which remains completely open along strike within an 850m long gold in soil anomaly.

De deeper drilling in BREDD002 discovered an epithermal system, returning 19.6 m at 436g/t AgEq over 10 m (CMVDD001), providing shallow follow up targets. The Chumavichi target represents a district scale corridor of epithermal mineralization, with at least 3 separate vein systems confirmed by Terra's drilling to date. Previous drilling at Chumavichi returned grades of 824.2g/t AgEq Over 4 m (CMVDD001, 505.3g/t AgEq and 284g/t AgEqover 10 m (CMVDD004) and 284g/t Ag Eq over 10 m (CMVD004) and 284g and 10 m (CMVDD002), as well as several structural zones hosted intermediate sulphidation epithermal Mineralization; Drillholes CMV 25001 through 25004 have intercepted several zones of shallow, massive sulphides and quartz-sulphides, vein-hosted mineralized intervals, have both intercepted a ca., 50-60 m interval of Retrograde altered skarn, the hosts of the previously reported 0. 61g/t AuEq Over 10 m (CMVDD003) and 284g/t AuEq across 10 m (CMVDD005), as well as several structural zone hosting intermediate sulphidation epither mal mineralization; Drillholes CM V25001 through 25004 have intercept multiple zones of shallow, massive sulfide and quartz-sulPHide, vein-hosted Mineralization in the hanging and foot wall of the SW dipping ChumAVichi structure, all above 80m depth; Epithermal mineralized intervals have been intersecting similar styles of mineralization indicating the epithermal structures are numerous and trend towards surface where an epithermal structures are numerous.

The Chumavichi targets. The Chumavichichi target represents a district scale zone of epithermal structures are numerous, with at least 3 separate veins and at Chumavichi target. Previous drilling at ChumAVichi returned grades of epithermal structures are numerous and trend towards surface.

Previous drilling at Chumvichi returned grades of epither malmal structures are also intercepted a ca.
