Terra Balcanica Drills 636 g/t Ag Eq. Over 4.3 m At Cumavici Ridge in Bosnia and Herzegovina
Rhea-AI Summary
Terra Balcanica (OTC:TEBAF) reported high‑grade Phase III drill results at Cumavici Ridge, Bosnia, including 636 g/t Ag Eq over 4.3 m in hole CMV25004 with higher included intervals of 1,757 g/t Ag Eq over 0.8 m and 1,319 g/t Ag Eq over 0.4 m.
The company says mineralization remains open along strike and down dip; assays used stated metal prices and assumed recoveries; further drilling is underway to test westward and down‑dip extensions.
Positive
- High‑grade intercept: 636 g/t Ag Eq over 4.3 m in CMV25004
- Very high included samples: 1,757 g/t Ag Eq over 0.8 m and 1,319 g/t Ag Eq over 0.4 m
- Drill collars show 100% core recovery for CMV25003/CMV25004
- Mineralization remains open along strike and down dip, enabling resource upside
Negative
- Reported intervals are drilled lengths, not true widths; true geometry is undetermined
- AgEq calculations rely on assumed metal prices and recoveries, introducing valuation sensitivity
- Results are limited to one vein system within a larger license; other targets remain untested

Vancouver, British Columbia, Feb. 23, 2026 (GLOBE NEWSWIRE) -- Terra Balcanica Resources Corp. (“Terra” or the “Company”) (CSE:TERA; FRA:UB1; OTC:TEBAF) is pleased to announce further high-grade assay results from the Phase III drill campaign at the Cumavici Ridge polymetallic, epithermal vein zone within its principal Viogor-Zanik project in eastern Bosnia and Herzegovina.
Highlights
- Drillhole CMV25004 intersected 636 g/t Ag Eq. over 4.3 m including:
-
- 1,757 g/t Ag Eq over 0.8 m
- 1,319 g/t Ag Eq over 0.4 m
- CMV25004 has tested new ground with the collar located 54 m southeast of CMVDD003 which reported 465.5 g/t Ag Eq. over 8.7 m and 27 m SW of CMV23004 which reported 1,168 g/t Ag Eq. over 1.35 m;
- Results confirm the high-grade nature and continuity of mineralisation at Cumavici Ridge, which marks just one vein system within the wider Cumavici license area;
- Mineralization at Cumavici remains open along strike and down dip to southwest;
- Additional Phase III drill testing of the Cumavici Ridge system continues.
Terra Balcanica CEO, Dr. Aleksandar Mišković, commented: “Terra continues proving up our flagship shallow, fault hosted, epithermal system. The drill intercepts with individual samples up to

Drillcore Observations
The mineralisation encountered in drillholes CMV25003 and CMV25004 are examples of the typical high grade, massive sulphides of polymetallic nature present within the Cumavici target. The Cumavici Ridge mineralization, which includes the reported drillholes is just one example of a series of underexplored polymetallic veins that form part of a regional NW/SE trending epithermal system. Mineralization is typified by massive sulphides which can be broadly grouped into a silver-antimony rich, sulphosalts-dominant interval and a colloform banded orange-purple zinc-lead interval of massive sphalerite-galena.

Geology of Cumavici Ridge
The Cumavici license is dominated by volcanic rocks (tuffs and pyroclastic breccias) which have been crosscut by generally NW-SE trending structures and are part of a large epithermal mineral system. Mineralization is silver and antimony dominant with further gold-lead-zinc (Figure 2).
Terra’s drilling has confirmed three polymetallic systems so far: Joseva, Cumavici Crest, and the flagship vein system at Cumavici Ridge. The Cumurnica and Kazani targets remain to be drilled. Mineralisation is characterised by sphalerite-stibnite-galena and further sulphosalts minerals which are associated with quartz and calcite veining and breccia cement. The mineralisation occupies faults which crop out at surface as distinctive topographic lows, coinciding with magnetic lows and often with mineralisation visible within fault gouge.
