# 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-staging.minestarters.com/news/abrasilver-expands-diablillos-mineral-resource-estimate-to-248-million-ounces-co--fa1eaa64-4409-4663-94c4-dfb289e56823 Original source: https://orestocks.com/company/ABRA.V/press-releases/6359969025077010 Publisher: orestocks Original announcement: 2026-05-07T01:15:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-01T03:56:37.868Z Atlas analysis updated: 2026-10-01T03:56:37.868Z - Company: AbraSilver - Ticker: ABRA - Exchange: TSX - Region: Argentina - Primary commodity: Silver - Secondary commodities: Gold - Document categories: Resource update - Extracted: 2026-10-01 03:56:38 UTC Narrative sentiment: 0.90 · Bullish ## Minestarters Atlas summary AbraSilver has announced an updated Mineral Resource Estimate for its Diablillos property in Argentina, significantly expanding the Measured & Indicated \(M&I\) categories. The M&I resource now totals 232 million tonnes, containing 248 million ounces of silver and 2.54 million ounces of gold \(454 Moz AgEq\). This represents a substantial increase of 25% for contained silver and 48% for contained gold in M&I categories since the prior July 2025 estimate, driven by new drilling and improved geological understanding. The updated MRE will underpin a Definitive Feasibility Study for the tank leach operation and a Preliminary Economic Assessment for an additional heap leach option, both expected by Q2 2026. Reasoning: AbraSilver's updated MRE for Diablillos shows significant growth in Measured & Indicated resources, with contained silver increasing by 25% and gold by 48%, supporting upcoming DFS and PEA studies. The estimate is NI 43-101 compliant and signed by a Qualified Person. - Positive factor: Tonnage Growth - Positive factor: Contained Metal Growth - Positive factor: Category Upgrade - Positive factor: QP/CP Signed - Positive factor: NI 43-101 Compliant - Positive factor: DFS-Supporting - Positive factor: PEA-Supporting - Positive factor: Cut-off Disclosed Low confidence — this extraction should be reviewed alongside the original source.

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.
