## Minestarters Atlas summary

CopAur Minerals Inc. has released a Preliminary Economic Assessment \(PEA\) for its Kinsley Mountain Gold Project, highlighting robust economics with a post-tax NPV\(5%\) of US$147 million and an IRR of 66% at spot gold prices. The PEA is supported by a 52% increase in the project's mineral resource estimate, now totaling 742,000 Indicated ounces and 69,000 Inferred ounces of gold. The project is envisioned as an open-pit, heap-leach operation with a nominal mine life of four years, producing an average of 30,514 ounces of gold annually.

Reasoning: The PEA demonstrates compelling economics for the Kinsley Mountain Gold Project with a post-tax NPV\(5%\) of US$147 million and IRR of 66% at spot gold prices, supported by a 52% growth in the mineral resource estimate to 742,000 Indicated ounces and 69,000 Inferred ounces of gold, including high-grade zones. However, the project has a short mine life and some sulphide material requires complex processing.

Facts used in scoring: 33

## Classification and evidence

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The document announces an updated Mineral Resource Estimate \(MRE\) with a 52% growth over the previous MRE.

Evidence · text

> A 52% growth over the previous Mineral Resource Estimate \(" MRE "\)

**Tonnage Growth**

Polarity: positive

Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved.

Why it applies: The MRE shows a 52% growth in contained ounces compared to the previous estimate.

Evidence · text

> A 52% growth over the previous Mineral Resource Estimate \(" MRE "\) to 742,000 Indicated ounces at 1.11 grams-per-tonne \(" g/t "\) gold \(" Au "\) and 69,000 Inferred ounces at 1.98 g/t Au

**Contained Metal Growth**

Polarity: positive

Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.

Why it applies: The updated MRE reports 742,000 Indicated ounces and 69,000 Inferred ounces, representing a 52% growth in contained gold ounces.

Evidence · text

> A 52% growth over the previous Mineral Resource Estimate \(" MRE "\) to 742,000 Indicated ounces at 1.11 grams-per-tonne \(" g/t "\) gold \(" Au "\) and 69,000 Inferred ounces at 1.98 g/t Au

**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: The news release explicitly states that the engineering and financial information, as well as the scientific and technical information, have been reviewed and approved by Qualified Persons under NI 43-101.

Evidence · text

> The engineering and financial information as it relates to the PEA results contained in this news release has been reviewed and approved by Dr. Todd Harvey, PhD... and "Qualified Person" as defined in National Instrument 43-101... The scientific and technical information as it relates to geology & mineralization contained in this news release has been reviewed and approved by Kristopher J. Raffle, P.Geo... and "Qualified Person" as defined in National Instrument 43-101

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The company states that the technical report was prepared in compliance with NI 43-101 guidelines.

Evidence · text

> prepare a technical report in compliance with the guidelines of National Instrument 43-101 Standards of Disclosure for Mineral Projects \(" NI 43-101 "\)

**Inferred Resource**

Polarity: negative

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

Why it applies: The MRE includes 69,000 Inferred ounces of gold, which is a lower confidence category.

Evidence · text

> 69,000 Inferred ounces at 1.98 g/t Au

**PEA-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.

Why it applies: The resource estimate is presented as part of a Preliminary Economic Assessment \(PEA\).

Evidence · text

> results of the Preliminary Economic Assessment \(the " PEA "\)

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The MRE table clearly lists the cutoff grades for different material types and classifications.

Evidence · table

> 0.2

Context: Oxide

**Heap Leach Route**

Polarity: neutral

Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.

Why it applies: The PEA is based on an open-pit mining and heap leach stacking processing route.

Evidence · text

> open-pit, heap-leach project

**Refractory Ore**

Polarity: negative

Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.

Why it applies: The document mentions custom oxidation by roaster or autoclave for sulphide material, indicating complex metallurgy.

Evidence · text

> custom oxidation of the flotation concentrates by roaster or autoclave for the Secret Canyon sulphide and Dunderberg Shale and Hamburg Formation sulphide material

## 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.
