Summary

AbraSilver Resource Corp. announced high-grade drill results from its Diablillos project in Argentina, highlighted by 109.0 metres grading 221.2 g/t silver and 0.72 g/t gold at Oculto West, including a bonanza intercept of 14.0 metres at 580 g/t silver. These results confirm mineralization continuity in a previously undrilled area and extend it beyond the current conceptual open pit, indicating strong potential for Mineral Resource growth. The company also provided an updated Mineral Resource Estimate as of April 30, 2026, detailing significant silver and gold resources across Measured, Indicated, and Inferred categories for both tank and heap leach processes.

Reasoning: AbraSilver reported exceptional drill results from its Diablillos project, including a broad, high-grade silver-gold intercept of 109.0 m at 221.2 g/t silver and 0.72 g/t gold in a previously undrilled area at Oculto West, demonstrating significant resource growth potential. The release also provides an updated Mineral Resource Estimate, reinforcing the project's scale.

Positive factors

  • High-grade silver-gold intercept in previously undrilled area
  • Extension of mineralization beyond current conceptual open pit
  • Potential for significant Mineral Resource growth
  • Comprehensive QA/QC disclosure and QP sign-off

Negative factors

  • True widths are not yet known for drill intercepts
  • Resource estimate cut-off grade is not a single explicit value but derived from economic parameters

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

Facts used in scoring: 14

Classification and evidence

Bonanza Interceptpositive

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

Why it applies: The intercept of 14.0 m at 580 g/t silver is exceptionally high-grade, well above typical thresholds for silver deposits.

Evidence · text

“14.0 m at 580 g/t silver”

Apparent Width Onlynegative

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 'Widths are reported as drilled; true widths are not yet known' for all drill results.

Evidence · text

“Widths are reported as drilled; true widths are not yet known.”

Step-Out Extensionpositive

Mineralization extended beyond the previously known limit.

Why it applies: Hole DDH 26-036 was drilled in a 'previously undrilled gap at Oculto West' and 'confirms the continuity of mineralization across this interval', extending known mineralization.

Evidence · text

“Hole DDH 26-036 intersected 109.0 metres ("m") grading 221.2 g/t silver and 0.72 g/t gold from 114.0 m downhole in a previously undrilled gap at Oculto West, confirming the continuity of mineralization across this interval.”

QA/QC Disclosedpositive

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

Why it applies: The release includes a detailed 'QA/QC and Core Sampling Protocols' section mentioning industry standard methodologies, blanks, certified reference materials, duplicate core samples, chain-of-custody, and analysis by ASA (Alex Stewart Argentina) using multi-element ICP/AES and Fire Assay.

Evidence · text

“AbraSilver applies industry standard exploration methodologies and techniques, and all drill core samples are collected under the supervision of the Company's geologists in accordance with industry best practices. ... Samples are then bagged, and quality control materials are inserted at regular intervals at site; these include blanks and certified reference materials as well as duplicate core samples ... All samples are received by the ASA (Alex Stewart Argentina) preparation laboratory in Salta ... All samples are analyzed using a multi-element technique consisting of a four-acid digestion followed by ICP/AES detection, and gold is analyzed by 50g Fire Assay with an AAS finish.”

QP/CP Signedpositive

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: David O'Connor P.Geo., Chief Geologist for AbraSilver, is the Qualified Person as defined by National Instrument 43-101 and has reviewed and approved the scientific and technical information. Luis Rodrigo Peralta, B.Sc., FAusIMM CP (Geo), is an Independent Qualified Person under NI 43-101 for the resource estimate.

Evidence · text

“David O'Connor P.Geo., Chief Geologist for AbraSilver, is the Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects, and he has reviewed and approved the scientific and technical information in this news release.”

NI 43-101 Compliantpositive

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

Why it applies: The resource estimate is stated to be in accordance with NI 43-101, and the QP for the resource estimate is an Independent Qualified Person under NI 43-101.

Evidence · text

“The Mineral Resource was estimated by Luis Rodrigo Peralta, B.Sc., FAusIMM CP (Geo), an INSA Consultora Managing Principal Geologist, and an Independent Qualified Person under NI 43-101.”

Measured Resourcepositive

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

Why it applies: The resource estimate includes 'Measured' category for both Tank Leach and Heap Leach oxides, totaling 66,512 kt.

Evidence · table

“Measured”

Context: 41,042

Indicated Resourcepositive

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

Why it applies: The resource estimate includes 'Indicated' category for both Tank Leach and Heap Leach oxides, totaling 165,469 kt.

Evidence · table

“Indicated”

Context: 60,978

Inferred Resourcenegative

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

Why it applies: The resource estimate includes 'Inferred' category for both Tank Leach and Heap Leach oxides, totaling 49,347 kt.

Evidence · table

“Inferred”

Context: 14,400

Cut-off Undisclosednegative

High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: The resource estimate footnotes describe a conceptual Whittle open pit shell and a Net Value per block (NVB) calculation to constrain the resource, but no single explicit cut-off grade (e.g., g/t or %) is stated for the resource itself.

Evidence · text

“The Mineral Resource is reported inside a conceptual Whittle open pit shell derived using US$ 34.50/oz Ag price, US $3,200/oz Au price, 86.6% process recovery for Au, and 80.9% process recovery for Ag, for the tank leaching and 74.3% process recovery for Au, and 46.8% process recovery for Ag, for the secondary heap leaching. Open pit optimization was constrained using a dual-process approach... A Net Value per block [NVB] calculation was used to constrain the Mineral Resource...”

Resource Updateneutral

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

Why it applies: The document presents 'Table 2 - Diablillos Mineral Resource Estimate - As of April 30, 2026', which is a formal update to the project's mineral resources.

Evidence · text

“Table 2 - Diablillos Mineral Resource Estimate - As of April 30, 2026”

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.
