# Tertiary Minerals reveals latest "incredibly compelling" silver results from Mushima North project Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/tertiary-minerals-reveals-latest-incredibly-compelling-silver-results-from-mushi--a7ffc128-fe9f-4f67-9ec0-e0c416fef682 Original source: https://www.proactiveinvestors.com/companies/news/1098686/tertiary-minerals-reveals-latest-incredibly-compelling-silver-results-from-mushima-north-project-1098686.html Publisher: proactiveinvestors Original announcement: 2026-09-17T10:41:48.478Z 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, Zinc - Document categories: Drill results - Extracted: 2026-09-17 11:37:36 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Tertiary Minerals reported high-grade silver-copper drilling results at the Mushima North project in Zambia. A key intercept of 82m at 107 g/t silver equivalent was highlighted, including a 37m high-grade section, with results suggesting the Discovery Zone remains open at depth. Reasoning: The announcement reports a high-grade, wide silver-equivalent intercept \(82m at 107 g/t AgEq\) that exceeds previous results and suggests the deposit remains open at depth. - Positive factor: Highest-grade silver-copper intersection reported to date - Positive factor: Significant width \(82m\) at high silver equivalent grade - Positive factor: Hole ended in mineralisation suggesting depth potential - Positive factor: Discovery Zone expansion potential noted Facts used in scoring: 6 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 659 g/t silver assay is exceptionally high for silver Evidence · text > highest individual silver assay to date at 659 g/t **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Holes ended in mineralisation beyond current Exploration Target boundary Evidence · text > Two of the four newly reported holes ended in mineralisation beyond the current Exploration Target boundary. ## Extracted facts Stored fact records: 6.

Why it applies: qaqc\_disclosed is not true **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: no cutoff\_grade was stated **Metal Equivalent Opaque** Polarity: negative Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent. Why it applies: an equivalent grade is reported without its assumptions ### 26TMNRC-066 [Link to this fact](https://atlas-extractions.minestarters.com/news/tertiary-minerals-reveals-latest-incredibly-compelling-silver-results-from-mushi--a7ffc128-fe9f-4f67-9ec0-e0c416fef682#fact-drill-facts-1) Mushima North · copper #### Identity - Hole ID: 26TMNRC-066 - Project: Mushima North - Commodity: copper - Region: zambia - Reported Region: zambia - Ticker: TYM #### Geometry - Grade: 0.2 - Grade Unit: % - Intercept: 82 m - From: 8 m - To: 90 m - Intercept Depth: 8 m #### Classification - Sample Type: drill - Group ID: 26TMNRC-066:8-90 #### QA/QC - QA/QC Methods: standards #### Review - Needs Review: No - Interp.

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.
