# Transatlantic Mining: Drilling Results at the Golden Jubilee Mine Include an Intersection of 6.1 m at 13.1 g/t Au Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/transatlantic-mining-drilling-results-at-the-golden-jubilee-mine-include-an-inte--61365101-7194-4420-b103-7807957d9764 Original source: https://money.tmx.com/en/quote/TCO/news/8804583968758829/transatlantic-mining-drilling-results-at-the-golden-jubilee-mine-include-an-inte Publisher: tmx Original announcement: 2023-04-13T21:22:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Transatlantic Mining Corp. - Ticker: TCO - Exchange: TSX - Region: Montana, USA - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Drill results, Metallurgy - Extracted: 2026-09-13 03:09:29 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Transatlantic Mining has announced inaugural reverse circulation drilling results from the Golden Jubilee Mine in Montana, highlighting high-grade gold intercepts including 6.1 m at 13.1 g/t Au. The results confirm the continuity of the mineralized structure and suggest potential for further expansion along strike and into parallel zones. Reasoning: Inaugural drilling campaign returned strong gold grades \(up to 17.3 g/t\) and demonstrated continuity of the mineralized structure, supporting potential for further expansion. - Positive factor: High-grade gold intercepts - Positive factor: True width disclosed - Positive factor: Step-out extension - Positive factor: QA/QC Disclosed Facts used in scoring: 8 ## Classification and evidence **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: The release explicitly states true widths for the reported intercepts \(e.g., 8.0 m true width\). Evidence · text > 8.0 m true width **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release mentions the use of blanks and standards in the assay process. Evidence · text > blanks and standards inserted on batches of 25 **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Mineralization was intersected down dip and along strike of existing drill holes and underground workings. Evidence · text > mineralized structure continues down dip and along strike **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The 3.0 m at 17.3 g/t Au intercept is exceptionally high grade. Evidence · text > 3.0 metres at 17.3 g/t Au **Gravity Route** Polarity: neutral Definition: Gravity separation forms a material part of the flowsheet. Why it applies: the document describes a gravity route \("gravity"\) **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 3 distinct composites were tested ## Extracted facts Stored fact records: 8.

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.
