# AbraSilver Expands Diablillos Mineral Resource Estimate to 248 Million Ounces Contained Silver and 2.5 Million Ounces Contained Gold \(454 Moz AgEq\) in M&I Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/abrasilver-expands-diablillos-mineral-resource-estimate-to-248-million-ounces-co--0e11d3fd-83aa-45d9-8506-37016ebe7e7f Original source: https://money.tmx.com/en/quote/ABRA/news/6359969025077010/abrasilver-expands-diablillos-mineral-resource-estimate-to-248-million-ounces-co Publisher: tmx Original announcement: 2026-05-06T21:15:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: AbraSilver Resource Corp. - Ticker: ABRA - Exchange: TSX - Region: Argentina - Primary commodity: Silver - Secondary commodities: Gold - Document categories: Resource update, Economic study - Extracted: 2026-09-19 07:25:19 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary AbraSilver Resource Corp. announced an updated Mineral Resource Estimate for its Diablillos project in Argentina, reporting a significant increase in Measured & Indicated \(M&I\) resources to 232 Mt, containing 248 Moz silver and 2.54 Moz gold \(454 Moz AgEq\). This represents a substantial growth of 25% for silver, 48% for gold, and 30% for silver-equivalent contained metal since the prior July 2025 estimate. The updated MRE, which includes both tank and heap leach components, will underpin an upcoming Definitive Feasibility Study and Preliminary Economic Assessment, with further resource updates anticipated in Q1 2027. Reasoning: The updated MRE shows substantial growth in contained metal for both silver and gold in the Measured & Indicated categories, significantly expanding the project's scale and advancing it towards a DFS. The inclusion of a large heap leach component also adds value by converting lower-grade material. While some grades have decreased, the overall increase in contained metal and project advancement are strong positives. - Positive factor: Significant increase in contained silver \(25%\) and gold \(48%\) in M&I categories compared to prior estimate, indicating substantial growth. - Positive factor: Total M&I resource now exceeds 450 Moz AgEq, demonstrating a large-scale project. - Positive factor: Expansion of the heap leach component, converting lower-grade material into potentially economic mineralization, improving overall project economics. - Positive factor: Updated MRE will underpin a DFS for tank leach and a PEA for heap leach, indicating project advancement towards development. - Positive factor: QP signed off on the estimate, and NI 43-101 compliance is stated, ensuring high reporting standards. - Negative factor: Some deposits show a decrease in average grade for silver and gold in the M&I categories compared to the prior estimate, despite tonnage increases. - Negative factor: The heap leach M&I resource shows a significant decrease in average silver and gold grades compared to the prior estimate, indicating dilution. Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 201 ## 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 reports an updated Mineral Resource estimate for the Diablillos property. Evidence · text > AbraSilver Expands Diablillos Mineral Resource Estimate to 248 Million Ounces Contained Silver and 2.5 Million Ounces Contained Gold \(454 Moz AgEq\) in M&I **Contained Metal Growth** Polarity: positive Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes. Why it applies: Contained silver in M&I increased by 25%, gold by 48%, and silver-equivalent by 30% since the prior estimate. Evidence · text > The contained metal in M&I has increased by a substantial 25% for silver, 48% for gold and 30% for silver-equivalent since the prior mineral resource estimate \(the "Prior MRE"\) from July 2025. **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The MRE was prepared in accordance with NI 43-101 and CIM Definition Standards. Evidence · text > The updated MRE was prepared by Luis Rodrigo Peralta, B.Sc., FAusIMM CP \(Geo\), an INSA Consultora Managing Principal Geologist, and an independent Qualified Person under National Instrument NI 43-101 - Standards of Disclosure for Mineral Projects \("NI 43-101"\), and in accordance with Canadian Institute of Mining, Metallurgy and Petroleum \("CIM"\) Definition Standards incorporated, by reference, and in compliance with NI 43-101 and has been reviewed internally by AbraSilver. **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: Luis Rodrigo Peralta, an independent Qualified Person, estimated and approved the MRE. 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. **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: The updated MRE will underpin an accompanying Preliminary Economic Assessment \(PEA\) of the additional heap leach option. Evidence · text > The updated MRE will underpin the upcoming Definitive Feasibility Study \("DFS"\) on the proposed tank leach operation and an accompanying Preliminary Economic Assessment \("PEA"\) of the additional heap leach option, expected by the end of Q2 2026. **DFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence. Why it applies: The updated MRE will underpin the upcoming Definitive Feasibility Study \(DFS\) on the proposed tank leach operation. Evidence · text > The updated MRE will underpin the upcoming Definitive Feasibility Study \("DFS"\) on the proposed tank leach operation and an accompanying Preliminary Economic Assessment \("PEA"\) of the additional heap leach option, expected by the end of Q2 2026. **Metal Equivalent Opaque** Polarity: negative Story-specific tag Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent. Why it applies: The AgEq formula is provided, but the specific gold and silver prices and recoveries used for the AgEq calculation in the tables are not explicitly stated alongside the AgEq grades, only for the pit shell optimization. Evidence · text > The formula for calculating AgEq is as follows: Silver Eq Oz = Silver Oz + Gold Oz x \(Gold Price/Silver Price\) x \(Gold Recovery/Silver Recovery\). **Grade Decline** Polarity: negative Definition: Average grade fell below the red-flag bound vs prior estimate — deposit economics worsening.

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.
