# Metallic Minerals Expands La Plata Copper-Silver Inferred Resource by 23% and Adds Platinum, Palladium and Gold Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/metallic-minerals-expands-la-plata-copper-silver-inferred-resource-by-23-and-add--b7a835c8-4ca9-4918-9595-d8dad66609d3 Original source: https://money.tmx.com/en/quote/MMG/news/8206569427739113/metallic-minerals-expands-la-plata-copper-silver-inferred-resource-by-23-and-add Publisher: tmx Original announcement: 2026-01-26T12:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Metallic Minerals Corp. - Ticker: MMG - Exchange: TSX - Region: Colorado - Primary commodity: Copper - Secondary commodities: Silver, Platinum, Palladium, Gold - Document categories: Resource update - Extracted: 2026-09-16 10:58:41 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Metallic Minerals has updated its La Plata project's Allard deposit Inferred Resource, expanding tonnage by 23% to 181.4 Mt. The update includes the addition of platinum, palladium, and gold, resulting in a total copper-equivalent grade of 0.36% CuEq. Reasoning: The update significantly expands the resource tonnage and adds high-value precious metals, though it remains entirely in the Inferred category. - Positive factor: Tonnage growth of 23% vs prior estimate - Positive factor: Addition of high-value PGE and gold credits - Positive factor: Significant contained metal scale \(1,307 Mlbs Cu\) - Positive factor: Open to expansion at depth and along strike - Negative factor: 100% Inferred category limits economic confidence - Negative factor: PGE/Au component constrained by limited historic assaying Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 5 ## Classification and evidence **Tonnage Growth** Polarity: positive Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved. Why it applies: The Inferred Resource tonnage expanded by 23% compared to the previous 2023 estimate. Evidence · text > expands the Inferred Resource tonnage by 23% **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource estimate was prepared in accordance with NI 43-101 standards. Evidence · text > announce an updated NI 43-101 Mineral Resource Estimate **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed.

Why it applies: Brian Hartman, M.S., P.Geo. is named as the responsible Qualified Person. Evidence · text > The QP responsible for this Mineral Resource estimate is Brian Hartman, M.S., P.Geo. **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: The NSR cut-off of US$18/t is clearly stated. Evidence · text > The resource is estimated using an NSR cut-off of US$18/t ## Extracted facts Stored fact records: 5.

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.
