Terra Balcanica Drills 636 g/t Ag Eq. Over 4.3 m At Cumavici Ridge in Bosnia and Herzegovina

TERA · Price
Executive Summary
- Terra Balcanica announced high‑grade assay results from Phase III drilling at the Cumavici Ridge vein system, including a standout intercept of 1,757 g/t Ag Eq over 0.8 m and additional intervals of 1,319 g/t and 636 g/t Ag Eq.
- The drill holes confirm continuity of mineralisation, open strike‑wise and down‑dip, and demonstrate the presence of significant base‑metal (Sb, Zn, Pb) and precious‑metal (Au, Ag) grades.
- Results support Terra’s view that Cumavici Ridge is a flagship shallow epithermal system with strong investment potential given proximity to existing infrastructure and European markets.
Key Details
- Hole CM 25004: 4.30 m interval – 636 g/t Ag Eq (including 0.8 m @ 1,757 g/t Ag Eq; 0.4 m @ 1,319 g/t Ag Eq).
- Hole CM 25003: 4.10 m interval – 108 g/t Ag Eq (including 0.2 m @ 1,606 g/t Ag Eq).
- Individual sample grades within the intercepts: up to 7.23 % Sb, 23.4 % Zn, 3.69 g/t Au, 420 g/t Ag, and 12.5 % Pb.
- Drill collars located 54 m SE of CMVDD003 (previously 465.5 g/t Ag Eq over 8.7 m) and 27 m SW of CMV23004 (1,168 g/t Ag Eq over 1.35 m).
- Mineralisation remains open along strike and down‑dip to the southwest; further Phase III drilling is ongoing.
- Geological context: Vein system hosted in volcanic tuffs/pyroclastic breccias with NW–SE trending structures; mineralisation comprises silver‑antimony rich sulphosalts and a zinc‑lead interval of massive sphalerite‑galena.
- QA/QC: Samples analysed by ALS Bor (Serbia) and ALS Loughrea (Ireland) under ISO/IEC 17025:2017; 17 % control sample insertion rate.
- Qualified Person: Dr. Aleksandar Mišković, President & CEO, NI 43‑101 Qualified Person.
