# Tertiary Minerals MD: 'Really very impressive' grades as Mushima North deepens Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/tertiary-minerals-md-really-very-impressive-grades-as-mushima-north-deepens--54ed0532-8749-4a6f-9da3-9172da56a8fb Original source: https://www.proactiveinvestors.com/companies/news/1098174/tertiary-minerals-md-really-very-impressive-grades-as-mushima-north-deepens-1098174.html Publisher: proactiveinvestors Original announcement: 2026-09-07T11:31:45.899Z 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: 2026-09-07 11:33:36 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Tertiary Minerals has reported encouraging drilling results at the Mushima North project in Zambia, extending mineralisation at depth with silver-equivalent grades exceeding 100g/t. The company is currently advancing towards a maiden mineral resource estimate expected by year-end and is conducting metallurgical test work. Reasoning: The announcement reports high-grade silver-equivalent intercepts \(>100g/t\) and successful depth extension at the Mushima North project, which is a significant exploration milestone. - Positive factor: extension of mineralisation at depth - Positive factor: high-grade silver-equivalent intercepts \(>100g/t\) - Positive factor: potential for oxide-to-sulphide transition - Positive factor: near-term open-pit potential - Negative factor: sulphide transition remains untested - Negative factor: maiden resource estimate still pending Facts used in scoring: 3 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling has extended mineralisation beyond the depth of the existing exploration target at Target A1. Evidence · text > drilling has extended mineralisation beyond the depth of the existing exploration target at Target A1 **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Silver equivalent grades over 100g/t are noted as 'really very impressive'. Evidence · text > Silver equivalent grades over 100g a tonne. Really very impressive ## 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.
