## Minestarters Atlas summary

US Copper Corp. has engaged Libertas Metallurgy Limited to review existing metallurgical work and design a testwork program for an upcoming Pre-Feasibility Study \(PFS\) at the Moonlight-Superior project. The company is also planning a deep drilling program to expand its copper resources in California.

Reasoning: The company is de-risking its project by engaging expert consultants to design metallurgical testwork for an upcoming PFS, building on a previously released PEA.

- Positive factor: Engagement of specialized metallurgical consultant Libertas

- Positive factor: Advancement toward Pre-Feasibility Study \(PFS\)

- Positive factor: Strategic alignment with US domestic copper production goals

- Negative factor: Resource is currently categorized as Inferred in the PEA

Facts used in scoring: 1

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The company is engaging consultants to design testwork for flotation and leaching, implying a mill-based processing route.

Evidence · text

> Their area of expertise is in flotation, leaching, process design

**Inferred Resource**

Polarity: negative

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

Why it applies: The PEA mentioned in the document includes Inferred Mineral Resources that are considered too speculative for reserves.

Evidence · text

> includes Inferred Mineral Resources that are considered too speculative geologically

copper

#### Identity

- Commodity: copper
- Ticker: USCU

#### Test Work

- Program Status: scoping
- Sample: Moonlight-Superior Project resource \(PEA\)

#### Recovery

- Recovery: 75 %
- Recovery Basis: theoretical

#### Lab

- Consultant: Libertas Metallurgy Limited

#### Review

- Needs Review: No
- Historical: No

#### Dates

- Event date: 2025-09-03T00:00:00.000Z

Reasoning: The 75% recovery is a stated assumption used for the PEA cutoff grade calculation, not a result from new testwork.

- Negative factor: Recovery is an assumption for cutoff calculation, not a test result

Evidence · text

> metallurgical recovery of 75% for copper

## 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.
