# Aston Bay Files Technical Report for Storm Copper Project Initial Mineral Resource Estimate Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/aston-bay-files-technical-report-for-storm-copper-project-initial-mineral-resour--099bd279-bf86-485c-a4fc-e66a65d0bb36 Original source: https://money.tmx.com/en/quote/BAY/news/7917089179057486/aston-bay-files-technical-report-for-storm-copper-project-initial-mineral-resour Publisher: tmx Original announcement: 2025-04-17T23:20:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Aston Bay Holdings Ltd. - Ticker: BAY - Exchange: TSX - Region: Nunavut, Canada - Primary commodity: Copper - Secondary commodities: Silver - Document categories: Resource update - Extracted: 2026-09-13 15:01:11 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Aston Bay has filed an initial NI 43-101 Technical Report for the Storm Copper Project, detailing a Mineral Resource Estimate of 8.2 Mt Indicated and 3.3 Mt Inferred at 1.47% Cu and 3.1 g/t Ag respectively. The resource is primarily near-surface and accessible via open-pit mining, with all six deposits remaining open for expansion. Reasoning: Initial Mineral Resource Estimate \(MRE\) for the Storm Copper Project establishes a substantial copper-silver resource with high-grade near-surface zones and significant expansion potential. - Positive factor: High-grade near-surface copper resource - Positive factor: All six deposits remain open - Positive factor: Excellent beneficiation potential confirmed by metallurgical testwork - Positive factor: Significant growth potential with <5% of copper belt explored - Negative factor: Large Inferred component \(approx 30% of total tonnage\) Facts used in scoring: 28 ## Classification and evidence **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The report is explicitly stated as a National Instrument 43-101 Technical Report. Evidence · text > new National Instrument 43-101 \("NI 43-101"\) Technical Report **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable. Why it applies: The document describes an 'initial Mineral Resource Estimate'. Evidence · text > details an initial Mineral Resource Estimate \("MRE"\) **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: Yungang Wu, M.Sc., P.Geo. is named as the Qualified Person responsible for the MRE. Evidence · text > Yungang Wu, M.Sc., P.Geo. of P&E Mining Consultants Inc. is the Qualified Person ## Extracted facts Stored fact records: 28.

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.
