## Minestarters Atlas summary

US Copper Corp has retained Global Resource Engineering to conduct an updated Preliminary Economic Assessment \(PEA\) for the entire Moonlight-Superior Copper Project in California. The updated study aims to incorporate recent drilling results and newly defined oxide resources to evaluate the combined viability of the Moonlight, Superior, and Engels deposits.

Reasoning: The company is advancing its project by initiating an updated PEA that will consolidate multiple deposits and include new oxide resource definitions.

- Positive factor: Initiation of updated PEA covering entire project

- Positive factor: Inclusion of oxide resources in upcoming PEA

- Positive factor: Existing NI 43-101 resources at multiple deposits

- Negative factor: Reliance on historical 2018 PEA data for some components

- Negative factor: Significant portion of resources remain in inferred category

Facts used in scoring: 5

## Classification and evidence

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The document references multiple NI 43-101 resources and a technical report prepared under these standards.

Evidence · text

> three of which host National Instrument 43-101 \(" NI 43-101 "\) resources

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: A significant portion of the reported resources \(Superior and Moonlight inferred\) are in the speculative inferred category.

Evidence · text

> inferred resource of 109 million tons \(62 million tonnes\) averaging 0.24% copper

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: George Cole, a Registered Professional Geologist, is named as the Qualified Person who reviewed the release.

Evidence · text

> reviewed and approved by George Cole, M.Sc., Director of US Copper who is a "Qualified Person"

## 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.
