## Minestarters Atlas summary

Talisman Metals PLC has announced the first drill assay results from its Tirzzit Project in Morocco, confirming copper-silver mineralisation within the Late Precambrian basal series. Highlight intercepts include 1.56% Cu and 64 g/t Ag over 2m in hole TRC01. The company is currently conducting an ongoing RC drilling program to define the extent and geometry of the strata.

Reasoning: First assay results from the Tirzzit project confirm the presence of expected copper-silver mineralisation in the basal series strata with strong initial intercepts.

- Positive factor: consistent copper mineralisation confirmed

- Positive factor: high grade copper-silver intercepts

- Positive factor: QA/QC protocols disclosed including certified lab and CRM

- Positive factor: Qualified Person sign-off provided

- Negative factor: limited number of field duplicates reported

Facts used in scoring: 15

## Classification and evidence

**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: Release includes details on blanks, field duplicates, and CRMs, and names a certified lab.

Evidence · text

> The QA/QC protocol included the systematic insertion of blank samples and field duplicates

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: The document notes that true width is expected to be 90 to 100% of downhole thickness.

Evidence · text

> True width is expected to be 90 to 100% of down hole thickness

Reasoning: Expanded from assay table. 19 % copper is exceptional against the default band \[2.5, 1, 0.5, 0.25\] %. Grade×width 1672.0 %·m is exceptional.

- Positive factor: 19 % copper is exceptional on the default band.

- Negative factor: Scored from rubric bands during table expansion, not from document context.

#### Tags used in scoring

**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: qaqc\_disclosed is 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

## 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.
