# Oroco Drills 234.6 metres of 0.52% CuEq at Santo Tom&\#xE1;s Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/oroco-drills-234-6-metres-of-0-52-cueq-at-santo-tom-xe1-s--3355f319-8408-4d73-9c19-562a3f8721b2 Original source: https://money.tmx.com/en/quote/OCO/news/7955518806752306/oroco-drills-234-6-metres-of-0-52-cueq-at-santo-tom-xe1-s Publisher: tmx Original announcement: 2026-10-08T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-10T02:22:01.012Z Atlas analysis updated: 2026-10-10T02:22:01.012Z - Company: Oroco Resource Corp. - Ticker: OCO - Exchange: TSX - Region: Sinaloa, Mexico - Primary commodity: Copper - Secondary commodities: Molybdenum, Gold, Silver, Zinc, Lead - Document categories: Drill results - Extracted: 2026-10-10 02:22:01 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Oroco Resource Corp. reported the fifth batch of assay results from its Phase 2 resource drilling program at the Santo Tomás copper project in Mexico, highlighting a 234.6-meter intercept of 0.52% CuEq in hole S045. The program, which has completed 50 holes, continues to confirm and extend mineralization, with several holes reinforcing higher-grade zones and suggesting potential pit limit extensions. These results are expected to positively influence the project's next economic assessment and support the conversion of Inferred Mineral Resources to the Indicated category. Reasoning: The announcement reports strong copper equivalent drill results from the Santo Tomás project, with a headline intercept of 234.6 m at 0.52% CuEq in S045, which is a significant width and above the project's average copper grade. The infill drilling largely confirms the existing block model and extends mineralization, supporting resource expansion and de-risking. While true widths are not yet confirmed, the overall results are positive for project viability and future economic assessments. The high-grade polymetallic intercept in S050 is notable but lacks a processing plan. - Positive factor: Broad intercept of 234.6 m at 0.52% CuEq in hole S045, which is above the project average grade for copper \(0.384%\) and a significant width. - Positive factor: Multiple other strong intercepts, including 86.1 m at 0.60% CuEq in S049 and 84.2 m at 0.58% CuEq in S053, reinforcing higher-grade zones. - Positive factor: Infill drilling largely supports the PEA Block Model and confirms grade continuity, de-risking the resource. - Positive factor: Potential for pit limit extension suggested by mineralization below the PEA pit and near-surface mineralization on the western margin. - Positive factor: Detailed QA/QC procedures are disclosed, including certified labs and QP sign-off. - Negative factor: True widths are not yet confirmed for any reported intervals, which may overstate actual thickness. - Negative factor: Carbonate-hosted mineralization in S050, while high-grade for Zn-Pb-Ag-Au-Cu, currently has no planned processing route, limiting its immediate economic impact. Low confidence — this extraction should be reviewed alongside the original source.

Why it applies: no cutoff\_grade was stated ### S044 [Link to this fact](https://atlas-staging.minestarters.com/news/oroco-drills-234-6-metres-of-0-52-cueq-at-santo-tom-xe1-s--3355f319-8408-4d73-9c19-562a3f8721b2#fact-drill-facts-102) Santo Tomás · copper Historical result Needs review: historical\_restatement #### Identity - Hole ID: S044 - Project: Santo Tomás - Commodity: copper - Region: mexico - Reported Region: mexico - Ticker: OCO #### Geometry - Grade: 0.43 - Grade Unit: % - Intercept: 234.6 m - From: 174.1 m - To: 408.7 m #### Classification - Deposit Type: porphyry - Sample Type: drill #### Location - Location: central portion of the South Pit - Loc. Source: document #### QA/QC - Laboratory: ALS Chemex - QA/QC Disclosed: Yes - QP Signed: Yes - QA/QC Methods: standards, blanks, duplicates #### Review - Needs Review: Yes - Review Reason: historical\_restatement - Interp. Status: scored - Historical: Yes #### Dates - Event date: 2026-10-08T00:00:00.000Z Reasoning: This is a very strong intercept with exceptional width and good grade for a porphyry copper deposit, exceeding the project average and confirming the resource model. - Positive factor: Exceptional intercept length of 234.6 m at a strong grade of 0.43% Cu \(0.52% CuEq\) for a porphyry deposit. - Positive factor: Grade is above the project's average copper grade \(0.384%\). - Positive factor: Infill hole supports the PEA Block Model, confirming grade continuity. - Negative factor: True width is not yet confirmed.

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.
