# Algo Grande Reports Results from Completed Phase I Drill Program at Cerro Grande Skarn Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/algo-grande-reports-results-from-completed-phase-i-drill-program-at-cerro-grande--340b9530-89e7-410d-98de-ec868f9a2231 Original source: https://money.tmx.com/en/quote/ALGR/news/7250163686926337/algo-grande-reports-results-from-completed-phase-i-drill-program-at-cerro-grande Publisher: tmx Original announcement: 2026-04-02T07:00:00.000Z 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: Silver, Gold, Molybdenum - Document categories: Drill results - Extracted: 2026-08-21 00:30:30 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Algo Grande's Phase I drilling at the Cerro Grande Skarn confirmed a vertically extensive, multi-horizon copper-silver-gold skarn system. The results include strong intercepts such as 18.2 m @ 1.8% CuEq and identify molybdenum zonation that vectors toward a potential porphyry source at depth. Reasoning: Phase I drilling confirmed a high-grade, multi-horizon skarn system with significant expansion potential and geochemical vectors for a deeper porphyry system. - Positive factor: strong copper-gold-silver mineralization - Positive factor: multiple stacked skarn horizons identified - Positive factor: molybdenum vectoring towards porphyry source - Positive factor: mineralization extends beyond historical limits - Negative factor: true widths unknown - Negative factor: drilling deviation noted in AG\_GC\_003 Facts used in scoring: 7 ## Classification and evidence **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 includes detailed QA/QC procedures, including blanks, standards, and duplicates, and mentions a certified laboratory \(ALS\). Evidence · text > Quality assurance and quality control procedures included the insertion of blanks, standards, and duplicates at regular intervals. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Results confirm mineralization extends beyond the limits of earlier drilling. Evidence · text > results from this program confirm that mineralization extends beyond the limits of earlier drilling **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The document explicitly states that true widths are unknown for the reported intervals. Evidence · text > Intervals reported are downhole lengths; true widths are unknown. ## Extracted facts Stored fact records: 7.

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.
