The company also provided updated Mineral Resource estimates, including 5.63 million tonnes Indicated and 874,000 tonnes Inferred, all effective December 31, 2025. This milestone establishes an initial three-year production profile for the mine and reflects updated geological information and cut-off grade assumptions. Reasoning: Magna Mining announced initial Probable Mineral Reserves for its McCreedy West Mine, establishing a three-year production profile, alongside updated Indicated and Inferred Mineral Resources, all compliant with NI 43-101 and supported by detailed technical parameters. - Positive factor: Maiden Mineral Reserve declared for McCreedy West Mine, providing a clear production profile. - Positive factor: Resource estimates updated to reflect recent drilling and depletion, maintaining a strong base. - Positive factor: Comprehensive disclosure of metal prices, recoveries, and cut-off grade assumptions for both reserves and resources. - Negative factor: Inferred Mineral Resources cannot be converted to Mineral Reserves, limiting immediate economic certainty for that portion. Facts used in scoring: 63 ## 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 McCreedy West Mine Mineral Reserves and Mineral Resources estimates disclosed herein were prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. Evidence · text > The McCreedy West Mine Mineral Reserves and Mineral Resources \(“MRMR”\) estimates disclosed herein were prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. **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: The Mineral Reserve estimate was prepared under the supervision of Mr. William van Breugel, P.Eng., B.A.Sc. Geological Engineering, Associate Engineer of SGS Geological Services and Mr. Henri Gouin, P.Eng., of SGS Geological Services, both are considered a "Qualified Person" as defined by NI 43-101. The Contact Nickel Mineral Resources were estimated by Mr. Allan Armitage, Ph.D., P.Geo., of SGS Geological Services., an independent Qualified Person as defined by NI 43-101. The Footwall Zone Mineral Resources were estimated by Jonathan Cirelli, P.Geo. of Orix Geoscience Inc. an independent Qualified Person as defined by NI 43-101. The scientific or technical information in this news release has been reviewed and approved by David King, M.Sc., P.Geo.

No prior estimate exists, so every change band is not applicable. Why it applies: Magna Mining Announces Initial Mineral Reserves for the McCreedy West Mine Evidence · text > Magna Mining Announces Initial Mineral Reserves for the McCreedy West Mine in Sudbury, Ontario **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: A cut-off grade was applied to each stope based on Net Smelter Return \(“NSR”\) exceeding sustaining development, equipment and fixed plant capital costs, as well as operating costs of CAD$180.00 per short ton. The Footwall Zone cut-off grade of 2.0% CuEq considers metal prices of $7.72/lb Ni, $4.88/lb Cu, $18.12/lb Co, $1,410/oz Pt, $1,156/oz Pd, $3,815/oz Au, and $50/oz Ag. The Contact Zone cut-off grade of 1.1% NiEq considers metal prices of $8.50/lb Ni, $3.75/lb Cu, $17.00/lb Co, $950/oz Pt, $1,100/oz Pd and $1,950/oz Au.

Why it applies: no cutoff\_grade was stated **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: qp\_signed is true **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: reporting\_standards includes ni\_43\_101 **No Contained Metal** Polarity: negative Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting. Why it applies: contained\_metal was not reported **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: the release compares against a previous estimate **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: the release names the study this estimate supports ### inferred [Link to this fact](https://atlas-extractions.minestarters.com/news/magna-mining-announces-initial-mineral-reserves-for-the-mccreedy-west-mine-in-su--46603bf4-b333-435e-872f-414ce5ddbbdb#fact-resource-facts-62) McCreedy West Mine · silver #### Identity - Project: McCreedy West Mine - Commodity: silver - Region: canada\_on - Reported Region: Ontario, Canada - Ticker: NICU #### Resource scope - Estimate type: resource - Reporting standards: ni\_43\_101 - QP Signed: Yes - Qualified person names: Mr. Allan Armitage, Ph.D., P.Geo., Jonathan Cirelli, P.Geo. - Resource group id: resource:562b61c3d54815929c1a - Mining method: underground #### Resource Data - Category: inferred - Tonnes: 874000 - Grade: 4.12 - Grade Unit: g/t #### Prior Estimate - Resource Date: 2025-12-31 #### Metal Equivalent - Assumptions Disclosed: Yes #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2026-02-18T00:00:00.000Z Reasoning: Total Inferred Mineral Resource for silver, reflecting the updated estimate. - Positive factor: Total Inferred Resource for silver, contributing to the overall resource base. - Negative factor: Inferred category has lower confidence and cannot be converted to reserves.

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.
