## Minestarters Atlas summary

AbraSilver announced an updated mineral resource estimate for Diablillos in Argentina, with total M&I resources of 232 Mt containing 248 Moz silver and 2.54 Moz gold. The update significantly expands the heap-leach component and is based on drilling through December 31, 2025. The release also compares the new estimate with the July 2025 prior estimate and says a DFS and PEA are planned for Q2 2026.

Reasoning: The document announces an updated mineral resource estimate with substantial growth in contained silver, contained gold, and heap-leach tonnage. It is materially positive for the project and moderately novel because it also compares against the July 2025 prior estimate and includes revised assumptions.

- Positive factor: M&I resources increased to 232 Mt containing 248 Moz silver and 2.54 Moz gold

- Positive factor: heap leach M&I tonnage expanded to 130 Mt from 30.774 Mt prior

- Positive factor: updated MRE is supported by additional drilling and revised economic assumptions

- Positive factor: NI 43-101 compliant estimate signed by an independent Qualified Person

- Negative factor: cut-off grade methodology changed to Net Value per Block and differs from the prior MRE

- Negative factor: heap leach component is preliminary and will be further assessed in a PEA

- Negative factor: resource estimate is still subject to feasibility and reserve conversion

- Rubric flag: resource\_update should carry a stated project and region on every fact — Project and region were added where clearly stated, but the release does not explicitly state a province/administrative region for Diablillos beyond Argentina.

Facts used in scoring: 134

## Classification and evidence

**JORC Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard.

Why it applies: The release states the MRE was categorized in accordance with the CIM Definition Standards and explicitly references NI 43-101, not JORC; JORC does not apply here.

Evidence · text

> in compliance with NI 43-101 and has been reviewed internally by AbraSilver

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The estimate is explicitly described as prepared in accordance with NI 43-101.

Evidence · text

> in accordance with NI 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: A named Qualified Person signed off on the estimate and reviewed the technical content.

Evidence · text

> The Mineral Resource was estimated by Luis Rodrigo Peralta

**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 release states the cutoff methodology and the approximate cut-off grades for tank and heap leach.

Evidence · text

> average cut-off grade equivalent to ~39 g/t AgEq

**Step-Out Extension**

Polarity: positive

Story-specific tag

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The release says drilling expanded mineralization beyond the conceptual open pit margin and increased tonnage at Oculto and JAC.

Evidence · text

> extends well beyond the conceptual open pit margin

**Infill Drilling**

Polarity: neutral

Story-specific tag

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

Why it applies: The release says the Oculto and JAC increases were driven by infill drilling to connect gaps in the MRE blocks.

Evidence · text

> driven by infill drilling to connect gaps in the MRE blocks

**Nearology Play**

Polarity: neutral

Story-specific tag

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: The release highlights multiple target areas extending from and connecting to existing deposits such as Oculto, JAC and Sombra.

Evidence · text

> extends southwest from Oculto

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

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

Why it applies: The release describes blanks, certified reference materials, duplicate core samples, chain of custody, laboratory preparation and re-analysis procedures.

Evidence · text

> include blanks and certified reference materials as well as duplicate core samples

**Apparent Width Only**

Polarity: negative

Story-specific tag

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

Why it applies: The release is a resource estimate table and does not provide drill intercept true widths or orientation for the resource rows.

Evidence · text

> Mineral Resource Estimate

**Compositing Transparent**

Polarity: positive

Story-specific tag

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The release states that drill hole intervals were composited to a length of 1 m and that grade capping was applied where appropriate.

Evidence · text

> Drill hole intervals were composited to a length of 1 m

Reasoning: Measured silver resource for Oculto within the updated April 30, 2026 Diablillos estimate. \(Expanded from multi-commodity resource table for completeness.\)

- Positive factor: measured resource disclosed for a named deposit

- Positive factor: high silver grade and large contained ounces

- Positive factor: project-level estimate is current and NI 43-101 compliant

- Negative factor: cut-off is based on Net Value per Block rather than a simple fixed grade cut-off

- Negative factor: open-pit resource estimate is still not a reserve

#### Tags used in scoring

**Measured Resource**

Polarity: positive

Definition: Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves.

Why it applies: category is "measured"

**Cut-off Disclosed**

Polarity: positive

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

Why it applies: cutoff\_grade is stated

**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: qp\_signed is true

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: reporting\_standards includes ni\_43\_101

**No Contained Metal**

Polarity: negative

Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained\_metal was not reported

## 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.
