Terra Balcanica drills 72.3 m of 0.27 g/t Au at Brezani

Dr. Aleksandar Miskovic reports TERRA BALCANICA INTERSECTS GOLD MINERALIZATION OVER 72 M AND STARTS DRILL PROGRAM AT BREZANI TARGET IN BOSNIA Terra Balcanica Resources Corp. has expanded the surface gold skarn system at Brezani and started the phase III drill program at its Viogor-Zanik project, Bosnia and Herzegovina. Highlights: The Brezani drill hole BRE23001, located 125 metres (m) south-southwest of the maiden Brezani drill hole, intercepted 0.27 gram per tonne (g/t) gold (Au) over 72.3 m, including 0.62 g/t Au over 7.5 m. Additionally, two antimony veined zones, 1.5 and 0.5 m wide, were intersected, respectively. The drill hole BRE23002, located 145 m northwest of BRE23001, intercepted 1.51 per cent zinc (Zn) over six m, including 0.54 per cent antimony (Sb) over 1.65 m, as well as 0.6 g/t Au over 2.85 m. The drill hole BRE23003, located 77 m southeast of the maiden Brezani drill hole, encountered 0.19 per cent Sb over 2.0 m, as well as 0.6 g/t Au over 2.85 m. The drill hole BRE23004, located 92 m north-northwest of the maiden Brezani drill hole, intercepted 0.62 g/t Au over 11.8 m, including 1.03 g/t Au over 6.65 m. Exploration upside: Gold-bearing, retrograde, chlorite overprinted skarn at Brezani has been now confirmed over 200 m in the north-south direction as it overlies the southeastern extent of the 1.2-kilometre (km), northeast-shallowing conductor interpreted to be Sb-Ag-Zn (antimony-silver-zinc) mineralized. The maiden Brezani drill hole BREDD002 intercepted 0.61 g/t gold equivalent (AuEq) over 88.0 m from surface (see the company's news release from Jan. 24, 2023). Terra Balcanica's chief executive officer, Dr. Aleksandar (Alex) Miskovic, commented: "We are pleased to have expanded the gold footprint at Brezani. The gold-bearing metasomatized hornfels intercepted from surface at BREDD002 three years ago were not just a one-off as the follow-up drilling clearly suggests a skarn with the gold mineralization over 200 m laterally. Being close to the surface, this is a considerable value add at Brezani given the northeast-shallowing, 20 m wide, fault-hosted silver antimony horizon, which is the real focus of the current phase III drill program." Brezani is located 8.4 km south of the Mineco Ltd. Sase mine, which produces approximately 330,000 tonnes (t) of lead-zinc-silver-gold concentrate per year. The target hosts components of a large magmatic-hydrothermal system discovered by airborne TEM-magnetic and geochemical surveys. The BRE23001 through 23004 diamond drill holes are located within the gold-in-soil anomaly, and were intended to assess lithological variability and grade of the gold skarn along strike. Additionally, the drill holes tested the resistive volume above an abrupt change into a central magnetic-low shell within the general more-than-95th-percentile magnetic-high anomaly to verify the lateral extent of 0.61 g/t AuEq. The BRE23001 drill hole was initially characterized by mudstone with patchy calc-silicate alteration and disseminated and vein-hosted pyrite-pyrrhotite followed by calc-silicate hornfels with pyroxene veining and disseminated and quartz veinlet hosted chalcopyrite, pyrite and pyrrhotite. Medium-grained garnet dominant exoskarn mineralogy is noted adjacent to chlorite-sericite altered diorite intrusives that have been altered to endoskarn with garnet and pyroxene. A gradient from garnet to pyroxene skarn can be observed in BRE23001 with movement away from the intrusive contact. Epithermal quartz-carbonate veining with arsenopyrite and stibnite was observed as well. There was notably more intrusive within the shallow part of BRE23001 than BREDD002. Quartz veins are crosscut by later pyrite and then carbonate-sulphide veins, which create a strong chlorite vein selvage, commonly with pyrrhotite. The BRE23004 intersected eight m of exo-skarn/calc-silicate (9.5 m to 19.5 m) with small intervals of intrusive adding up to around two m. The altered rock may not strictly be a skarn as the grain size is not coarse. The mineral banding is very well developed and is larger grained on the whole that our classic calc-silicate. The banding appears to follow relict bedding and tectonic folding. The skarn mineralogy contains pyroxene-garnet-wollastonite-calcite-actinolite-chlorite-epidote. There appears to be zonation with the upper part containing more light brown garnet bands and the lower part more dominant in blue pyroxene. An example of a similarly altered, blue pyroxene skarn interval returned up to 2.7 g/t gold in BREDD002 from 37 m to 38 m. The intrusive appears to be sillicified possibly overprinting potassic with some sections altered to endoskarn. From 19.5 m to 29 m is exoskarn/calc-silicate dominant with small intervals of porphyry with some intervals altered to exoskarn. Banding within the skarn is nicely well developed and similar to previous intervals. Phase III drilling The 2025 drill program is a follow-up onto the discovery made by the drill hole BREDD002, which intercepted circa 20 m of intermediate sulphidation, base-metal-rich, fault-breccia hosted Ag-Sb-Zn mineralization grading upward of 436 g/t silver equivalent (AgEq), which was previously detected via the 2021 heliborne TEM survey. The EM study revealed a 1.2 km long conductor shallowing toward northeast and eventually surfacing at the topographic high of the Brezani locality. 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 updip during the current drill program. 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 as observed in BREDD002 offering a massive potential for a large-tonnage orebody, which is the goal of this year's campaign. The company's field team expressly built six drill pads on a challenging and steep terrane, and the drilling has commenced in earnest last Friday. Terra expects to complete the first diamond drill hole by the end of August, 2025, with the laboratory assays in hand by mid- to late September, 2025. A total of 2,100 m of drilling is planned with a possibility of increasing the program should intercepts justify further testing. QA/QC (quality assurance/quality control) Half-core (PQ3 and HQ3) samples were delivered to ALS Bor, Serbia, for sample preparation and subsequent wet chemical analysis at the Loughrea laboratory in Ireland, an ISO/IEC 17025:2017-certified test facility. Sample preparation PREP-31BY method involved crushing the core to 70 per cent less than two millimetres (mm), rotary split 1.0 kilogram (kg) and pulverizing the split to greater than 85 per cent passing 75 microns. Silver and base metals were analyzed by ICP-MS (inductively coupled plasma mass spectrometry) after a four-acid digest (ME-MS61). Gold was assayed by 30-gram (g) fire assay with ICP-AES (inductively coupled plasma atomic emission spectroscopy) finish (Au-ICP21). Overlimit samples for base metals were reanalyzed by the four-acid digest ICP-AES analyses termed ME-OG62. Control samples comprising the certified reference material CDN-ME-1501 (Canadian Resource Labs Ltd.), quarter-core field duplicates and blanks were inserted at a rate of 5 per cent and investigated as part of the company's quality assurance and quality control program.
