# Tertiary Minerals MD: High-grade zone at Mushima North "holding together very nicely" Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/tertiary-minerals-md-high-grade-zone-at-mushima-north-holding-together-very-nice--e631ebfe-f260-44e3-bb04-dd71aa6e8e0b Original source: https://www.proactiveinvestors.com/companies/news/1098754/tertiary-minerals-md-high-grade-zone-at-mushima-north-holding-together-very-nicely-1098754.html Publisher: proactiveinvestors Original announcement: 2026-09-18T11:46:55.781Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Tertiary Minerals PLC - Ticker: TYM - Exchange: Unavailable - Region: Zambia - Primary commodity: Silver - Secondary commodities: Copper - Document categories: Drill results, Resource update - Extracted: 2026-09-18 11:50:13 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Tertiary Minerals has reported encouraging drill results at the Mushima North project in Zambia, including a significant 82m intercept at 107 g/t silver equivalent. The drilling has extended the mineralised zone beyond previous boundaries and demonstrated grade consistency, supporting the company's goal of a maiden Mineral Resource by year-end. Reasoning: The announcement reports significant high-grade silver equivalent drill intercepts and successful zone extension, which are key catalysts for the upcoming maiden Mineral Resource. - Positive factor: High-grade silver equivalent intercept reported - Positive factor: Mineralisation extended beyond existing Exploration Target boundary - Positive factor: Grade consistency noted across wider zone - Positive factor: Presence of copper and critical minerals \(bismuth, antimony\) Facts used in scoring: 2 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling successfully extended the zone beyond the existing Exploration Target boundary. Evidence · text > Several drill holes have also ended in mineralisation beyond the existing Exploration Target boundary. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 191 g/t silver equivalent is exceptionally high for the context. Evidence · text > 37 metres at 191 grams per tonne **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 document mentions the results are from a drilling programme, though specific lab/QP details are in the interview context.

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.
