# FTSE 100 Live: FTSE 100 slides as Wall Street turns mixed Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/ftse-100-live-ftse-100-slides-as-wall-street-turns-mixed--6cc5a4ac-4c4c-4a0b-a351-fe25052b4dee Original source: https://www.proactiveinvestors.com/companies/news/1098732/ftse-100-live-ftse-100-slides-as-wall-street-turns-mixed-1098732.html Publisher: proactiveinvestors Original announcement: 2026-09-18T16:00:44.065Z 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: 2026-09-18 16:03:04 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Tertiary Minerals PLC has identified a high-grade silver-copper-zinc zone at its Mushima North project in Zambia. The drilling results indicate that the mineralisation extends beyond the current Exploration Target and remains open at depth. Reasoning: The announcement reports a significant high-grade silver-copper-zinc zone that extends beyond previous targets and remains open at depth, representing a strong exploration success. - Positive factor: high-grade zone identified - Positive factor: mineralisation extends beyond exploration target - Positive factor: remains open at depth 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 shows mineralisation extending beyond the current Exploration Target. Evidence · text > mineralisation extending beyond the current Exploration Target ## 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.
