Minestarters Atlas analysis
Summary
Tertiary Minerals has reported high-grade silver, copper, and zinc drill results from its Phase 4 programme at the Mushima North Project in Zambia. The results delineate a substantial high-grade zone at Target A1 that remains open at depth and along strike.
Reasoning: High-grade silver-copper-zinc intercepts reported at Target A1, extending the known mineralised footprint.
Positive factors
- high-grade silver intercepts
- continuation beyond target boundary
- Discovery Zone remains open at depth and strike
Negative factors
- true widths unknown
- assays for 8 holes still pending
Facts used in scoring: 10
Classification and evidence
Apparent Width Onlynegative
Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.
Why it applies: The document explicitly states that true widths for the reported intervals remain unknown.
Evidence · text
“true widths for these intervals remain unknown”
No QA/QC Disclosurenegative
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 does not disclose QA/QC procedures, lab certification, or QP sign-off.
Evidence · text
“Results have been released for 29 of the 39 RC drill-holes”

Why it applies: qaqc_disclosed is not true
Cut-off Undisclosednegative
High-grade interval reported without stating the cut-off grade used for compositing.
Why it applies: no cutoff_grade was stated
Nearology Playneutral
Value premise rests on proximity to a known deposit rather than own results.
Why it applies: proximity is offered as the value premise: "A separate, new shallow copper zone was intersected approximately 900m from the Discovery Zone in the Western Zone, with"

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
