## Minestarters Atlas summary

Tertiary Minerals has delineated a higher-grade silver-copper-zinc zone at the Mushima North Project in Zambia, with intercepts extending beyond the previous Exploration Target boundary. The results also include a new shallow copper discovery in the Western Zone and the detection of critical minerals like cobalt and bismuth.

Reasoning: Strong drill results delineating a higher-grade silver-copper-zinc zone that extends beyond previous targets, plus a new copper discovery in the Western Zone.

- Positive factor: Delineation of a higher-grade zone

- Positive factor: Mineralisation extends beyond previous Exploration Target boundary

- Positive factor: Discovery of new copper mineralisation in Western Zone

- Positive factor: Presence of critical minerals \(Co, Bi, Sb\)

- Negative factor: True widths unknown

- Negative factor: No metallurgical testwork completed yet

Facts used in scoring: 20

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drill results show continuation of mineralisation beyond the Exploration Target boundary.

Evidence · text

> Drill results show continuation of mineralisation beyond the Exploration Target boundary

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The release explicitly states that true widths are unknown for the reported intercepts.

Evidence · text

> downhole widths, true widths unknown

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release mentions certified laboratory analytical results.

Evidence · text

> following the recent reporting of laboratory analytical results

#### Tags used in scoring

**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: qaqc\_disclosed is not true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: proximity is offered as the value premise: "Add this to multiple drill-ready targets within 15km of Target A1 yet to be evaluated fully, the Mushima North Project i"

## 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.
