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
AbraSilver Delivers Expected Resource Growth Ahead of Feasibility Study, But Valuation Stretched

Executive Summary
- Headline: 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.
- Date: May 6, 2026.
- Core Update: The company reported an updated Mineral Resource Estimate (MRE) for the Diablillos project in Argentina.
- Resource Growth: Measured & Indicated (M&I) resources increased to 232 million tonnes containing 248 Moz Ag and 2.54 Moz Au (454 Moz AgEq). This represents a 25% increase in silver, 48% increase in gold, and 30% increase in silver-equivalent compared to the July 2025 estimate.
- Processing Strategy: The resource is split into two components: Tank Leach (102 Mt @ 65 g/t Ag) and Heap Leach (130 Mt @ 8 g/t Ag).
- Timeline: A Definitive Feasibility Study (DFS) for the tank leach operation and a Preliminary Economic Assessment (PEA) for heap leach are expected by the end of Q2 2026.
- Context: This update incorporates ~13,270 metres of additional drilling since July 2025, bringing the total database to over 170,000 metres.
Material Impact
- Expectation vs. Reality: The news aligns with previous guidance provided in October 2025 and July 2025 releases, which explicitly stated an updated MRE was expected in H1 2026. Therefore, the timing is not unexpected.
- Magnitude of Growth: A 30% increase in silver-equivalent resources (from 350 Moz AgEq to 454 Moz AgEq) is significant for project economics and supports a larger mine life or throughput potential. However, this growth was foreshadowed by consistent positive drilling results released monthly from late 2025 through April 2026 (e.g., Oculto East intercepts).
- Market Reaction Risk: The stock price has appreciated significantly from $3.15 in May 2025 to a high of $17.61 in February 2026, currently consolidating near $15.27. Much of the resource growth expectation appears priced into the current valuation.
- Strategic Value: The confirmation of dual-processing (Tank + Heap) enhances flexibility but does not fundamentally alter the project status from "development" to "production-ready" until the DFS is finalized and financing secured for construction.
- Conclusion: While the numbers are strong, the news is largely a confirmation of previously communicated milestones and drilling trends. It reduces execution risk slightly but does not offer a surprise catalyst that would justify a re-rating beyond current levels without further de-risking (e.g., final DFS economics or FID).
