# A8G: Near-surface tantalum mineralisation at Spodumene Hill Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/a8g-near-surface-tantalum-mineralisation-at-spodumene-hill--e5ab7922-f8fb-4137-901c-61e2079b3b7c Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03142089 Publisher: asx Original announcement: 2026-09-21T23:41:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-22T00:24:33.757Z Atlas analysis updated: 2026-09-22T00:24:33.757Z - Company: Australasian Metals Limited - Ticker: A8G - Exchange: ASX - Region: Côte d’Ivoire - Primary commodity: Tantalum - Secondary commodities: Lithium, Niobium, Tin - Document categories: Drill results, Other - Extracted: 2026-09-22 00:24:34 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Australasian Metals has reviewed historical data from the Atex Lithium-Tantalum Project in Côte d’Ivoire, confirming near-surface tantalum mineralisation. The review includes high-grade historical concentrate results and 2022 metallurgical studies indicating good liberation and beneficiation potential via gravity and magnetic separation. Reasoning: The release highlights significant historical tantalum potential at the Atex project, but the data is non-compliant, historical, and requires modern verification drilling. - Positive factor: historical high-grade concentrate grades - Positive factor: strong tantalum market prices - Positive factor: evidence of high liberation and physical beneficiation potential - Negative factor: data is historical and not JORC compliant - Negative factor: no modern QA/QC available for 1966 data - Negative factor: sample size for 2022 metallurgical work was noted as too small Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 6 ## Classification and evidence **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The announcement relies on historical 1966 data that has not been re-assayed or updated with modern JORC compliant results. Evidence · text > The 40-tonne figure is a historical estimate and is not JORC compliant **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: The release explicitly states that original 1966 laboratory sheets have not been located and no modern QA/QC applies to the historical data. Evidence · text > Original 1966 laboratory sheets have not been located or independently re-assayed. **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The company is positioning the project based on its proximity to and historical presence of tantalum mineralisation in the area. Evidence · text > historical data review confirms near-surface tantalum \(coltan\) mineralisation across Spodumene Hill area ## Extracted facts Stored fact records: 6.

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.
