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

Executive Summary

• Terra Balcanica Resources Corp. reports results from the initial phase of its Phase III drill program at the Brezani target within the Viogor-Zanik project in Bosnia and Herzegovina, confirming an expanded gold skarn system.
• Four new drill holes (BRE23001–BRE23004) were completed, intersecting significant gold mineralization and associated base metals (zinc, antimony), with Hole BRE23001 returning 72.3 meters at 0.27 g/t Au.
• The company has commenced a 2,100-meter Phase III drilling campaign aimed at testing the lateral extent and depth of a 1.2-kilometer-long, northeast-shallowing conductor interpreted to host Sb-Ag-Zn mineralization, with first assay results expected in mid-to-late September 2025.

Key Details

• Drill Hole BRE23001: Located 125m south-southwest of the maiden hole; intercepted 0.27 g/t Au over 72.3m, including 0.62 g/t Au over 7.5m. Also intersected two antimony veined zones (1.5m and 0.5m wide).
• Drill Hole BRE23002: Located 145m northwest of BRE23001; intercepted 1.51% Zn over 6m (including 0.54% Sb over 1.65m) and 0.6 g/t Au over 2.85m.
• Drill Hole BRE23003: Located 77m southeast of the maiden hole; encountered 0.19% Sb over 2.0m and 0.6 g/t Au over 2.85m.
• Drill Hole BRE23004: Located 92m north-northwest of the maiden hole; intercepted 0.62 g/t Au over 11.8m, including 1.03 g/t Au over 6.65m.
• Geological Context: Gold-bearing, retrograde, chlorite-overprinted skarn confirmed over 200m in the north-south direction. The target overlies a 1.2km northeast-shallowing conductor interpreted as Sb-Ag-Zn mineralized.
• Historical Context: The maiden hole (BREDD002) previously intercepted 0.61 g/t AuEq over 88.0m from surface.
• Phase III Program Scope:
  • Total planned drilling: 2,100 meters.
  • Goal: Test the lateral extent (1.2km length, up to 600m width, 20m thick) of the conductor and assess potential for a large-tonnage orebody.
  • Timeline: First diamond drill hole expected complete by end of August 2025; assays expected mid-to-late September 2025.
  • Potential for program expansion if intercepts justify further testing.
• QA/QC: Samples analyzed at ALS Bor, Serbia, and Loughrea laboratory, Ireland (ISO/IEC 17025:2017 certified). Gold assayed by 30g fire assay with ICP-AES finish; base metals by ICP-MS after four-acid digest. Control samples inserted at 5% rate.

Notable Quotes

• "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." — Dr. Aleksandar (Alex) Miskovic, CEO
