## Minestarters Atlas summary

Mako Mining has released an updated Mineral Resource Estimate for the Moss Mine in Arizona, reporting 646,000 ounces of gold and 6.8 million ounces of silver within Measured and Indicated categories. The resource is based on an optimized open pit shell with a 0.17 g/t AuEq cut-off grade.

Reasoning: Updated M&I resource for an existing open pit project with high-grade silver credits and clear technical sign-off.

- Positive factor: NI 43-101 compliant

- Positive factor: QP/CP signed

- Positive factor: Cut-off grade disclosed

- Positive factor: Open pit resource

- Negative factor: Significant Inferred component

Facts used in scoring: 14

## 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 resource estimate is reported in accordance with NI 43-101 standards.

Evidence · text

> in accordance with National Instrument 43-101

**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: Qualified Persons Chris Keech and Gary Wong are named and have verified the data.

Evidence · text

> Mr. Chris Keech, P.Geo. of CGK Consulting Services Inc., meets the requirements of a Qualified Person

**Inferred Resource**

Polarity: negative

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

Why it applies: The estimate includes an Inferred component which is speculative in nature.

Evidence · text

> There is an additional estimated Inferred open pit mineral resource

**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 cut-off grade of 0.17 g/t AuEq is clearly stated.

Evidence · text

> at a 0.17 g/t AuEq 1 cutoff

## 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.
