# Minto's First Mine Plan Takes 40% to 45% of the Indicated Resource Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/minto-s-first-mine-plan-takes-40-to-45-of-the-indicated-resource--4d02e41d-8f77-4138-bc3e-5b1c7d669d2c Original source: https://www.cruxinvestor.com/posts/mintos-first-mine-plan-takes-40-to-45-of-the-indicated-resource Publisher: cruxinvestor Original announcement: 2026-09-17T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Selkirk Copper Mines - Ticker: SCMI - Exchange: Unavailable - Region: Canada - Primary commodity: Copper - Secondary commodities: Gold, Silver - Document categories: Drill results, Resource update, Economic study - Extracted: 2026-09-17 19:39:52 UTC Narrative sentiment: 0.20 · Bullish ## Minestarters Atlas summary Selkirk Copper Mines is progressing its Phase 2 drilling at the Minto project, with 90% of the 50,000m program completed. Recent results are primarily infill, confirming geological models at Minto North and Area 118, though Copper Keel showed lower-than-expected grades. The company is using these results to inform a mine plan that currently incorporates 40-45% of the indicated resource, ahead of a PEA due in Q3 2026. Reasoning: The document reports a mix of confirmatory infill drilling and successful step-out hits, though some zones \(Copper Keel\) underperformed expectations. The core news is the progress of the Phase 2 program and its role in informing the upcoming mine plan and PEA. - Positive factor: Infill drilling confirms modeled geometry and grade estimation - Positive factor: Successful step-out drilling at Area 118 and 117 Lens - Positive factor: Large M&I resource base of 47.8 Mt - Negative factor: Copper Keel results were variable and lower than expected - Negative factor: Expansion potential limited at Copper Keel - Negative factor: Mine plan currently only captures 40-45% of indicated resource Facts used in scoring: 7 ## Classification and evidence **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: Most reported holes are classified as infill that confirms modeled geometry. Evidence · text > Most of the reported holes are classified as infill that confirms modeled geometry **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Successful step-out drilling reported at Area 118 and 117 Lens. Evidence · text > We've got new methods to expand existing zones, where we're doing step-out drilling, almost all of which has been successful **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions ALS laboratory and 15% QC material insertion. Evidence · text > operated by ALS, with quality-control material inserted at approximately 15% of all samples **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document discusses the current state of the MRE and its inclusion in the mine plan. Evidence · text > Management puts the share of the indicated resource currently reaching the mine plan at 40% to 45%. ## Extracted facts Stored fact records: 7.

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.
