# Orosur Mining Announces Discovery at El Cedro Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/orosur-mining-announces-discovery-at-el-cedro--9d089f90-3f2f-4d0d-9e49-bca0f4e5dba4 Original source: https://orestocks.com/company/OMI.V/press-releases/7335137524940453 Publisher: orestocks Original announcement: 2026-09-15T06:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Orosur Mining Inc. - Ticker: OMI - Exchange: Unavailable - Region: Colombia - Primary commodity: Gold - Secondary commodities: Copper - Document categories: Drill results, Other - Extracted: 2026-09-15 06:48:01 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Orosur Mining has announced its first drill results from the El Cedro prospect at the Anzá Project in Colombia. The hole CED001 intersected a 61.35m zone of gold mineralization grading 0.93 g/t Au from surface, confirming a broad intrusive-hydrothermal system. Reasoning: First drill results from the El Cedro prospect show a broad, continuous gold interval from surface, confirming the presence of a mineralised system as anticipated. - Positive factor: First hole at new prospect - Positive factor: Broad mineralised zone from surface - Positive factor: Discovery of porphyry/hydrothermal system - Negative factor: Copper grades below economic significance - Negative factor: True width not disclosed Facts used in scoring: 2 ## 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 mentions industry standard QAQC protocols including blanks, repeats, and CRMs. Evidence · text > Industry standard QAQC protocols are put in place with approximately 10% of total submitted samples being blanks, repeats or Certified Reference Materials \(CRMs\). **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 intercept is reported as downhole thickness with no true width provided. Evidence · text > Intersections are quoted as downhole thicknesses. True geological thicknesses are unknown. ## Extracted facts Stored fact records: 2.

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.
