# ARIS MINING EXPANDS HIGH-GRADE SEGOVIA RESERVE AND RESOURCE ESTIMATES Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/aris-mining-expands-high-grade-segovia-reserve-and-resource-estimates--59a8aaf1-24f8-449e-8ca8-7f545427d3b4 Original source: https://money.tmx.com/en/quote/ARIS/news/4852915833024889/aris-mining-expands-high-grade-segovia-reserve-and-resource-estimates Publisher: tmx Original announcement: 2026-01-08T22:18:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Aris Mining Corporation - Ticker: ARIS - Exchange: TSX - Region: Antioquia, Colombia - Primary commodity: Gold - Secondary commodities: None reported - Document categories: Resource update, Production - Extracted: 2026-08-24 23:00:15 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Aris Mining has updated its Segovia mineral reserve and resource estimates, reporting a 7% increase in Measured and Indicated resources and a 12% increase in both Inferred resources and Proven and Probable reserves. The update reflects successful exploration and resource-to-reserve conversion at the high-grade Segovia operations in Colombia. Reasoning: Significant expansion in both resource and reserve categories with high-grade continuity, supported by successful conversion and exploration success. - Positive factor: M&I resource growth of 7% - Positive factor: Inferred resource growth of 12% - Positive factor: Reserve growth of 12% - Positive factor: Exceptionally high-grade inventory - Positive factor: Successful conversion of resources to reserves Facts used in scoring: 5 ## Classification and evidence **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: Proven and probable reserves increased by 12% reflecting successful conversion of resources to reserves. Evidence · text > Proven and probable mineral reserves increased by 12% to 1.5 Moz, up from 1.3 Moz in the 2024 estimate, reflecting successful conversion of resources to reserves **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: Measured and indicated resources increased by 7% and inferred resources grew by 12%. Evidence · text > Measured and indicated mineral resources increased by 7% to 3.6 million ounces of gold \(Moz\), up from 3.4 Moz in the 2024 estimate, while inferred resources increased by 12% to 2.9 Moz **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: Pamela De Mark, P.Geo. is named as the Qualified Person for the 2025 MRE. Evidence · text > The 2025 MRE was prepared by Pamela De Mark, P.Geo., Senior Vice President of Geology and Exploration of Aris Mining, who is a Qualified Person as defined by NI 43-101. **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: Cut-off grades for both resources and reserves are disclosed. Evidence · text > The 2025 MRE utilized a gold cut-off grade of between 2.04 g/t and 2.95 g/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.
