## Minestarters Atlas summary

Prospect Resources Limited announced high-grade copper intercepts from infill drilling at Nyungu Central, including 10m at 1.10% Cu and 5.68m at 1.51% Cu, confirming continuity and strengthening confidence in the deposit. Regional exploration identified two significant copper anomalies at Shikezi, with the larger extending over 1km. Metallurgical testwork on Nyungu Central and Kabikupa composites returned excellent copper recoveries, supporting the Mumbezhi Copper Project's advancement towards a Scoping Study in Q1 2027.

Reasoning: The announcement reports strong copper grades from infill drilling at Nyungu Central, confirming continuity and enhancing confidence in the deposit. New copper anomalies identified at Shikezi highlight regional exploration potential, and metallurgical testwork shows excellent copper recoveries. However, some assays are pending, and true widths are not reported.

- Positive factor: High-grade copper intercepts from infill drilling

- Positive factor: Confirmation of continuity and quality of mineralization at Nyungu Central

- Positive factor: Identification of new significant copper anomalies at Shikezi

- Positive factor: Multiple drill rigs active across the project for resource growth and exploration

- Positive factor: Scoping Study on track for Q1 2027

- Positive factor: Excellent copper recoveries from metallurgical testwork

- Negative factor: Partial assays pending for some high-priority infill holes

- Negative factor: Aircore results are pXRF determinations, not lab assays, and are below resource cut-off

- Negative factor: True width not reported for drill intercepts

- Negative factor: Cobalt and gold grades in new intercepts are generally lower than project average

Low confidence — this extraction should be reviewed alongside the original source.

- Positive factor: New significant copper anomaly identified

- Positive factor: Good intercept width \(25m\)

- Positive factor: Open at end of hole, indicating potential for further mineralization

- Negative factor: Grade \(309 ppm Cu or 0.03% Cu\) is well below resource cut-off \(0.2% Cu\)

- Negative factor: Results are from pXRF, not certified lab assays

- Negative factor: True width not reported

#### 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

#### Rejected tags

**Apparent Width Only** — Rejected; excluded from scoring

Polarity: negative

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

Reason: The document explicitly states that downhole length is reported, not true width.

Evidence · text

> Down hole length is being reported, not the true width.

Reasoning: Expanded from assay table. 0.11 g/t gold is below against the open\_pit mining band \[5, 2, 1, 0.3\] g/t. Grade×width 1.1 g/t·m is below.

- Negative factor: 0.11 g/t gold is below the weak threshold \(0.3 g/t\) on the open\_pit mining band.

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

- Ticker: PSC

#### Test Work

- Program Status: detailed
- Test Type: flotation
- Processing Route: flotation
- Sample: Kabikupa lower grade fresh sulphide composite

#### Recovery

- Recovery: 94.3 %
- Recovery Basis: actual\_test
- Conc. Grade: 25
- Conc. Grade Unit: % Cu

#### Reagents

- Reagent Notes: Relatively high graphitic carbon levels \(up to 4.8% TGC\) presented no barrier to achieving good quality copper concentrates, with the use of carboxymethylcellulose \(CMC\), as an effective depressant for graphitic carbon.

#### Review

- Needs Review: No
- Historical: No

#### Dates

- Event date: 2026-10-14T00:00:00.000Z

Reasoning: Excellent copper recovery and high concentrate grade from Kabikupa lower grade fresh sulphide composite flotation testwork.

- Positive factor: Exceptional copper recovery \(94.3%\) for flotation

- Positive factor: High concentrate grade \(25.0% Cu\)

#### Tags used in scoring

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

## 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.
