# Algo Grande Identifies Additional Skarn Mineralization 3km South of Cerro Grande, With Samples Above 3% Copper and Confirms Copper in Multiple Targets on the Property Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/algo-grande-identifies-additional-skarn-mineralization-3km-south-of-cerro-grande--fb9c5db3-7338-4fc2-980c-e3c235e9df73 Original source: https://money.tmx.com/en/quote/ALGR/news/4890298309080976/algo-grande-identifies-additional-skarn-mineralization-3km-south-of-cerro-grande Publisher: tmx Original announcement: 2026-03-11T11:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Algo Grande Copper Corp. - Ticker: ALGR - Exchange: TSX - Region: Sonora, Mexico - Primary commodity: Copper - Secondary commodities: Gold, Silver - Document categories: Drill results, Other - Extracted: 2026-08-21 01:19:15 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Algo Grande has identified a new skarn zone at the Potrero South target, 3km south of Cerro Grande, with surface samples exceeding 3% Cu. The company also confirmed mineralization at several other targets, including the La Molina target identified via machine learning, and reported high-grade surface samples at Las Trancas. Reasoning: The announcement reports significant new skarn mineralization at Potrero South with high-grade surface samples and confirms multiple targets across the Adelita project, including machine-learning identified zones. - Positive factor: discovery of new skarn zone at Potrero South - Positive factor: high-grade surface samples exceeding 3% Cu - Positive factor: confirmation of mineralization at machine learning targets - Positive factor: expansion of Cerro Grande strike length - Negative factor: surface grab samples are selective and may not be representative Facts used in scoring: 8 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Discovery of a new skarn zone at Potrero South, 3km south of Cerro Grande. Evidence · text > led to the discovery of a new skarn zone at Potrero South target, located approximately 3 km south of the Cerro Grande central discovery **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 Hermosillo, ISO/IEC 17025 accreditation, and specific QA/QC protocols \(blanks, standards, duplicates\). Evidence · text > The Company maintains a QA/QC program that includes the insertion of certified reference materials, blanks, and duplicates at regular intervals. ## Extracted facts Stored fact records: 8.

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.
