## Minestarters Atlas summary

Axo Copper Corp. announced the acquisition of the San Antonio Gold Project in Sonora State, Mexico, from Osisko Development Corp. This transformational acquisition includes a past-producing asset with existing infrastructure and a significant NI 43-101 compliant mineral resource estimate for gold and silver. The project features an open-pit constrained resource with high-grade oxide material, offering potential for accelerated production.

Reasoning: Axo Copper is making a transformational acquisition of the San Antonio Gold Project, a past-producing asset with existing infrastructure and a significant NI 43-101 compliant gold and silver resource, which includes high-grade oxide material suitable for accelerated production.

- Positive factor: Acquisition of a past-producing asset

- Positive factor: Existing infrastructure \(heap leach pads, crushing facilities, carbon-in-column plant\)

- Positive factor: Significant NI 43-101 compliant resource estimate

- Positive factor: High-grade oxide resource amenable to heap leaching

- Positive factor: Supportive new shareholders \(Osisko Development and OR International\)

- Positive factor: QP/CP signed off on the resource estimate

- Negative factor: Resource estimate effective date is over 2 years old \(June 2022\)

- Negative factor: Permit application was withdrawn in 2022

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 82

## 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 presents a mineral resource estimate for the San Antonio Gold Project, which is being acquired by Axo Copper.

Evidence · text

> generating an initial open-pit mineral resource estimate totaling 576koz at 1.20g/t Au in the indicated category and 544koz at 1.02g/t Au in the inferred category.

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The mineral resource estimate is explicitly stated to be NI 43-101 compliant.

Evidence · text

> NI 43-101 Technical Report For The 2022 Mineral Resource Estimate On The San Antonio Project Sonora, Mexico

**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: Multiple Qualified Persons \(P.Geo., MAusIMM \(CP\)\) are named as having reviewed and validated the mineral resource estimate.

Evidence · text

> William J. Lewis P.Geo., et al \(the " San Antonio Report "\)is available for download from Osisko Development's SEDAR+ profile at www.sedarplus.ca . Charles Spath, P. Geo., has reviewed the San Antonio Report on behalf of the Company.

**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 grades for oxide, transition, and fresh rock zones are clearly stated.

Evidence · text

> The calculated economic cut-off grade for the resource in Oxides \(70% recovery\) is 0.27 g/t Au, Transition \(90% recovery\) is 0.44 g/t Au, and Fresh Rock \(90% recovery\) is 0.44 g/t Au.

**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 resource is in the Inferred category \(16.6 Mt at 1.02 g/t Au\).

Evidence · table

> 16.6

Context: Total Inferred

**Stale Estimate**

Polarity: negative

Definition: Effective date is &gt;2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: The effective date of the mineral resource estimate is June 24, 2022, which is over two years old relative to the announcement date of November 24, 2025.

Evidence · text

> effective June 24, 2022

## 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.
