## Minestarters Atlas summary

Bell Copper has completed drilling on hole K-23 at the Perseverance porphyry copper project in Arizona, intersecting Laramide-age porphyry units and a potential leached cap. While specific assay results for K-23 are pending, the geological observations support the existence of a porphyry copper system.

Reasoning: The announcement reports the completion of drilling \(K-23\) which intersected geological indicators of a porphyry copper system \(leached cap and Laramide porphyry\), though actual grades are pending assay.

- Positive factor: identification of leached cap

- Positive factor: intersection of Laramide porphyry units

- Positive factor: presence of alteration indicative of porphyry system

- Negative factor: no assay results reported for K-23 yet

Facts used in scoring: 2

## 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: The release mentions review and approval by a Qualified Person \(Timothy Marsh, PhD, PEng\).

Evidence · text

> The technical content of this release has been reviewed and approved by Timothy Marsh, PhD, PEng., the Company's CEO and President and a 'Qualified Person'

**Nearology Play**

Polarity: neutral

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

Why it applies: The value is driven by the proximity to a known porphyry system indicated by previous holes K-22 and K-20.

Evidence · text

> Previous drilling shows evidence of a nearby porphyry system

## 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.
