# Terra Balcanica Intercepts 607 g/t Ag Eq. Over 3.0 m and 670 g/t Ag Eq. Over 3.9 m At Cumavici in Bosnia and Herzegovina Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/terra-balcanica-intercepts-607-g-t-ag-eq-over-3-0-m-and-670-g-t-ag-eq-over-3-9-m--f7836032-ec09-4282-a340-29ffa36ad7ae Original source: https://finance.yahoo.com/news/terra-balcanica-intercepts-607-g-191500252.html Publisher: yahoo\_press Original announcement: 2026-03-17T19:15:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-20T18:15:45.185Z Atlas analysis updated: 2026-09-20T18:15:45.185Z - Company: Terra Balcanica Resources Corp. - Ticker: TERA - Exchange: CSE - Region: Bosnia and Herzegovina - Primary commodity: Silver - Secondary commodities: Antimony - Document categories: Drill results - Extracted: 2026-09-20 18:15:45 UTC Narrative sentiment: 1.00 · Bullish ## Minestarters Atlas summary Terra Balcanica Resources Corp. has announced high-grade drill results from its Phase III campaign at the Cumavici Ridge target in Bosnia and Herzegovina. Drillhole CMV25005 returned an intercept of 607 g/t Ag Eq. over 3.0 m, including a high-grade 1.7 m sub-interval containing 3.05% Sb. Reasoning: The intercept reports exceptionally high silver equivalent grades \(607 g/t\) and a high-grade antimony sub-interval \(3.05%\) in an epithermal vein setting. - Positive factor: exceptional silver equivalent grades - Positive factor: high-grade antimony inclusion Facts used in scoring: 3 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 842 g/t Ag Eq. is exceptionally high for an epithermal system. Evidence · text > 842 g/t Ag Eq **Deleterious Elements Present** Polarity: negative Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release. Why it applies: The intercept contains 3.05% antimony, which can be a penalty element. Evidence · text > 3.05% Sb ## Extracted facts Stored fact records: 3.

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.
