# Terra Balcanica Drills 636 g/t Ag Eq. Over 4.3 m At Cumavici Ridge in Bosnia and Herzegovina Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/terra-balcanica-drills-636-g-t-ag-eq-over-4-3-m-at-cumavici-ridge-in-bosnia-and--f16de739-46aa-4237-b655-1e264319f03f Original source: https://finance.yahoo.com/news/terra-balcanica-drills-636-g-130000382.html Publisher: yahoo\_press Original announcement: 2026-02-23T13:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-20T18:18:33.175Z Atlas analysis updated: 2026-09-20T18:18:33.175Z - Company: Terra Balcanica Resources Corp. - Ticker: TERA - Exchange: CSE - Region: Bosnia and Herzegovina - Primary commodity: Silver - Secondary commodities: None reported - Document categories: Drill results - Extracted: 2026-09-20 18:18:33 UTC Narrative sentiment: 1.00 · Bullish ## Minestarters Atlas summary Terra Balcanica Resources Corp. has reported high-grade silver equivalent drill results from its Phase III campaign at the Cumavici Ridge, part of the Viogor-Zanik project in Bosnia and Herzegovina. Drillhole CMV25004 returned 636 g/t Ag Eq over 4.3 m, including a very high-grade 0.8 m interval at 1,757 g/t Ag Eq. Reasoning: The intercept of 636 g/t Ag Eq over 4.3 m is exceptionally high for an epithermal system, and the sub-interval of 1,757 g/t Ag Eq is bonanza-grade. - Positive factor: Exceptional silver equivalent grade - Positive factor: High-grade sub-intervals Facts used in scoring: 2 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The sub-interval of 1,757 g/t Ag Eq is exceptionally high-grade for an epithermal system. Evidence · text > 1,757 g/t Ag Eq over 0.8 m ## Extracted facts Stored fact records: 2.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
