# Oroco Intersects 228 m of 0.49% CuEq and 212 m of 0.44% CuEq at Santo Tom&\#xE1;s Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/oroco-intersects-228-m-of-0-49-cueq-and-212-m-of-0-44-cueq-at-santo-tom-xe1-s--0b863c63-1d56-4b7b-a7df-730d3279c192 Original source: https://money.tmx.com/en/quote/OCO/news/5775925365794368/oroco-intersects-228-m-of-0-49-cueq-and-212-m-of-0-44-cueq-at-santo-tom-xe1-s Publisher: tmx Original announcement: 2026-05-21T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Oroco Resource Corp. - Ticker: OCO - Exchange: TSX - Region: Sinaloa, Mexico - Primary commodity: Copper - Secondary commodities: Molybdenum, Gold, Silver - Document categories: Drill results, Resource update - Extracted: 2026-09-16 14:54:31 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Oroco Resource Corp. reported significant Phase 2 drill results from the South Zone of the Santo Tomás copper project in Mexico. Key intercepts include 228.55 m at 0.38% Cu \(0.49% CuEq\) in hole S022 and 212.33 m at 0.34% Cu \(0.44% CuEq\) in hole S023, with elevated molybdenum grades noted at depth. Reasoning: Strong Phase 2 drill results from the South Zone confirm higher-grade mineralization and molybdenum enrichment, supporting the objective of resource conversion. - Positive factor: Significant width and grade intercepts in S022 and S023 - Positive factor: Elevated molybdenum grades increasing CuEq at depth - Positive factor: Confirmation of higher-grade South Zone mineralization - Positive factor: QA/QC protocols and QP sign-off disclosed - Negative factor: S024 intercepts do not reflect true width due to drill orientation Facts used in scoring: 54 ## 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 details on standards, blanks, duplicates, and laboratory protocols. Evidence · text > QA/QC protocols that include the insertion of certified reference standards, blanks, and duplicates. **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: S024 was not drilled perpendicular to mineralization and reported intervals do not reflect true width. Evidence · text > Reported mineralized intervals do not reflect true widths of the reported mineralization. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: Phase 2 is designed to convert Inferred resources to Indicated classification. Evidence · text > Phase 2 is designed primarily to convert Inferred resources to Indicated classification in the South Zone ## Extracted facts Stored fact records: 54.

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.
