Minestarters Atlas analysis
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 factors
- Highest-grade silver-copper intersection reported to date
- Significant width (82m) at high silver equivalent grade
- Hole ended in mineralisation suggesting depth potential
- Discovery Zone expansion potential noted
Facts used in scoring: 6
Classification and evidence
Bonanza Interceptpositive
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 Extensionpositive
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.”

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: 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
Metal Equivalent Opaquenegative
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

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.
