## Minestarters Atlas summary

Auro Metals Inc. announced positive assay results from the final five drill holes of its 2026 Phase I drill program at the Santa Barbara Gold-Copper Project in Ecuador. Highlights include 572.47m grading 0.60 g/t gold and 0.10% copper in hole DSB-74, extending known mineralization. The results confirm continuity and expand the known porphyry system, with a Phase II drill program already underway.

Reasoning: The announcement reports significant gold-copper intercepts from the final Phase I drill holes, including a very long intercept in DSB-74, which extends and confirms the continuity of mineralization within the Santa Barbara porphyry system.

- Positive factor: Significant gold-copper intercepts

- Positive factor: Extension of mineralization

- Positive factor: Confirmation of continuity

- Positive factor: Porphyry deposit type

- Positive factor: QA/QC and QP disclosed

- Negative factor: True width unknown

- Negative factor: Assays pending for some holes/intervals

Facts used in scoring: 24

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Hole DSB-74 intersected 572.47m grading 0.60 g/t Au, resulting in a gold grade-thickness product of 343.48 g/t·m, which exceeds the exceptional threshold of 300 g/t·m for gold.

Evidence · table

> 0.60

Context: 572.47

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drillholes DSB-73 and DSB-74 are step-out holes that extended previously drilled mineralization by almost 200m to the east, and Phase II includes a 400m step-out northeast of DSB-74.

Evidence · text

> Drillholes DSB-73 and DSB-74 are step-out holes, which have extended the previously drilled DSB-63 by almost 200m to the east.

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release details that samples were shipped to SGS, an ISO/IEC 17025 accredited laboratory, and that certified reference materials, blanks, and duplicates were inserted into sample sequences.

Evidence · text

> All samples in respect of the exploration program at the Project discussed in this news release were shipped in securely-sealed bags by a chartered commercial truck, directly from the field to the sample preparation facilities of SGS in Guayaquil, Ecuador for preparation, and to SGS in Lima, Peru for geochemical analysis. SGS is a global leader in inspection, verification, testing, and certification. It is an ISO/IEC 17025 accredited laboratory independent from Auro. All samples go through fire assay \(SGS code FAA313\) for gold and multi-acid digestion ICP-AES multi-element assay \(SGS code ICP40B\) for other elements. Certified reference materials, various types of blank samples and duplicate samples are inserted into normal drill core sample sequences prior to delivery to laboratory for preparation and analysis. The overall ratio of quality control samples in sample sequences is approximately 20%.

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The document explicitly states that the true width of mineralization is unknown for the reported drill intercepts.

Evidence · text

> True width of mineralization is unknown.

**Infill Drilling**

Polarity: neutral

Definition: Confirmatory drilling to raise resource confidence, not new discovery.

Why it applies: Drillholes DSB-71, DSB-72, and DSB-75 are described as infill/step-out holes, and DSB-75 specifically filled a 300m gap between historical holes.

Evidence · text

> Drillholes DSB-71, DSB-72 and DSB-75 are infill/step-out holes

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: The document reports Indicated resources of 29.8 million tonnes grading 0.73 g/t gold and 0.1% copper.

Evidence · text

> Indicated resources of 29.8 million tonnes grading 0.73 grams per tonne gold and 0.1% copper

**Inferred Resource**

Polarity: negative

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

Why it applies: The document reports Inferred resources of 205.7 million tonnes grading 0.52 g/t gold and 0.09% copper.

Evidence · text

> Inferred resources of 205.7 million tonnes grading 0.52 grams per tonne gold and 0.09% 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: The scientific and technical information has been reviewed and approved by Alex Zhang, P. Geo., a Qualified Person for NI 43-101.

Evidence · text

> The scientific and technical information contained in this news release has been reviewed and approved by Alex Zhang, P. Geo., a Director of the Company, who is a Qualified Person for the purposes of National Instrument 43-101 - Standards of Disclosure for Mineral Projects \( "NI 43-101"\).

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The mineral resource estimate was prepared in accordance with NI 43-101 by SRK Consulting.

Evidence · text

> mineral resource estimate prepared in accordance with NI 43-101 by SRK Consulting

## 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.
