# OROCO COMMENCES PHASE 2 DRILLING Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/oroco-commences-phase-2-drilling--4b6415e8-7fbc-4d94-b4e1-c560a4c40022 Original source: https://money.tmx.com/en/quote/OCO/news/7197072968120401/oroco-commences-phase-2-drilling Publisher: tmx Original announcement: 2026-02-24T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Oroco Resource Corp. - Ticker: OCO - Exchange: TSX - Region: northwestern Mexico - Primary commodity: Copper - Secondary commodities: None reported - Document categories: Resource update, Drill results - Extracted: 2026-09-16 15:01:51 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Oroco Resource Corp. has mobilized a diamond drill rig at its Santo Tomás copper project in Mexico to begin Phase 2 drilling. The program focuses on infill and confirmation drilling to upgrade resource classifications in the South Zone, alongside metallurgical and geotechnical work to support a Pre-Feasibility Study \(PFS\). Reasoning: The announcement marks the mobilization of a drill rig for infill and confirmation drilling to support resource upgrading and PFS-level technical studies at the Santo Tomás copper project. - Positive factor: Commencement of Phase 2 drilling - Positive factor: Focus on resource classification upgrade - Positive factor: Parallel PFS-standard metallurgical and geotechnical programs Facts used in scoring: 1 ## Classification and evidence **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The release explicitly states the program will prioritize infill and confirmation drilling to refine the geological and grade model. Evidence · text > Initial work will prioritize both infill and confirmation drilling **resource\_5** Polarity: positive Story-specific tag Definition: No canonical definition is currently available. Why it applies: The drilling is intended to support the upgrade of mineral resource classifications. Evidence · text > intended to support the upgrade of the mineral resource classifications **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The source explicitly discloses a revised resource estimate Evidence · text > revised mineral resource estimate ## Extracted facts Stored fact records: 1. Some facts used in scoring do not have a stored record. ## Resource Estimates (1) ### Fact 1 [Link to this fact](https://atlas-extractions.minestarters.com/news/oroco-commences-phase-2-drilling--4b6415e8-7fbc-4d94-b4e1-c560a4c40022#fact-resource-facts-0) Santo Tomás #### Identity - Project: Santo Tomás - Region: mexico - Reported Region: mexico - Ticker: OCO #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2026-02-24T00:00:00.000Z Reasoning: Mobilization of rig for infill/confirmation drilling to support resource upgrading. - Positive factor: Targeted at resource classification upgrade Evidence · text > mobilized a diamond drill rig to its Santo Tomás copper project... to commence drilling intended to support the upgrade of the mineral resource classifications in the project’s South Zone. #### Tags used in scoring **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: no cutoff\_grade was stated **No Contained Metal** Polarity: negative Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting. Why it applies: contained\_metal was not reported **No QP/CP Disclosure** Polarity: negative Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience. Why it applies: no Qualified or Competent Person is named anywhere in the release **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: the release compares against a previous estimate **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: the release names the study this estimate supports **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: the release names the study this estimate supports **DFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence. Why it applies: the release names the study this estimate supports ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
