# Brunswick Exploration Announces Inferred Mineral Resource of 52.2Mt at 1.08% Li2O at Mirage with Additional Exploration Target Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/brunswick-exploration-announces-inferred-mineral-resource-of-52-2mt-at-1-08-li2o--67b48928-9326-439e-aa59-c47971875175 Original source: https://money.tmx.com/en/quote/BRW/news/8792424392807761/brunswick-exploration-announces-inferred-mineral-resource-of-52-2mt-at-1-08-li2o Publisher: tmx Original announcement: 2026-01-08T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Brunswick Exploration Inc. - Ticker: BRW - Exchange: TSX - Region: Quebec, Canada - Primary commodity: Lithium - Secondary commodities: Tantalum - Document categories: Resource update, Other - Extracted: 2026-09-15 15:13:16 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Brunswick Exploration has announced a maiden Inferred Mineral Resource Estimate of 52.2 million tonnes at 1.08% Li2O and 131 ppm Ta2O5 at the Mirage Project in Quebec. The company also identified a significant conceptual exploration target of up to 50Mt in the same area. Reasoning: The announcement of a maiden 52.2Mt lithium resource at a high grade is a major milestone for the company, though it remains entirely in the Inferred category. - Positive factor: Maiden resource establishes a significant scale \(52.2Mt\) - Positive factor: High grade \(1.08% Li2O\) for a lithium resource - Positive factor: Large contained metal \(563,000 t Li2O\) - Positive factor: Significant exploration target \(40-50Mt\) adjacent to MRE - Positive factor: Near-surface mineralization \(70% within 150m depth\) - Negative factor: 100% Inferred category \(low geological confidence\) - Negative factor: No economic evaluation or demonstrated economic viability produced Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 2 ## Classification and evidence **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: First formal MRE for the Mirage Project. Evidence · text > announce a maiden, open-pit Mineral Inferred Resource Estimate **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The entire resource is classified as Inferred. Evidence · text > Inferred Mineral Resource Estimate \(“ MRE ”\) of 52.2 million tonnes **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: MRE prepared in accordance with NI 43-101 standards. Evidence · text > prepared in accordance with the National Instrument \(“ NI”\) 43-101 standards **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: Qualified Persons Pierre Luc Richard and Patrick Frenette are named. Evidence · text > The independent qualified persons for the MRE... is Pierre Luc Richard, P.Geo., of PLR Resources Inc., with contributions from Patrick Frenette, P.Eng. ## Extracted facts Stored fact records: 2.

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.
