# Monarca Minerals Reports Completion of Phase 1 Exploration Drilling at San Jose Project and Preliminary Results Including 4.07 G/t Au over 3.0m Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/monarca-minerals-reports-completion-of-phase-1-exploration-drilling-at-san-jose--e16776fa-164e-4fa8-91a1-0506ecdf7078 Original source: https://money.tmx.com/en/quote/MMN/news/5047341353918527/monarca-minerals-reports-completion-of-phase-1-exploration-drilling-at-san-jose- Publisher: tmx Original announcement: 2021-11-09T13:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Monarca Minerals, Inc. - Ticker: MMN - Exchange: TSX - Region: Mexico - Primary commodity: Gold - Secondary commodities: Silver, Copper, Lead, Zinc - Document categories: Drill results, Other - Extracted: 2026-08-23 22:55:35 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Monarca Minerals has completed its Phase 1 RC drilling program at the San Jose project in Mexico, reporting several significant gold and base metal intercepts. The results demonstrate widespread mineralization within skarn and altered intrusive rocks, targeting IP anomalies. Reasoning: The release reports promising initial assay results from a Phase 1 RC drilling program, intersecting significant gold and base metal mineralization in skarn-style targets. - Positive factor: significant precious and base metal mineralization - Positive factor: skarn mineralization potential - Positive factor: widespread mineralization - Negative factor: true widths unknown - Negative factor: assay results still pending for some holes Facts used in scoring: 23 ## 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: The release mentions procedures including blanks, standards, and duplicates, and a QP review. Evidence · text > A sterile blank sample \(un-mineralized basalt\) and a mineralized reference standard \(used by Monarca since 2009\) are alternately placed in the sample sequence every 20th sample. **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 due to insufficient drilling. Evidence · text > True widths are unknown at this time due to insufficient drilling ## Extracted facts Stored fact records: 23. Some facts used in scoring do not have a stored record. ## Drill Results (23) ### SJ01 [Link to this fact](https://atlas-staging.minestarters.com/news/monarca-minerals-reports-completion-of-phase-1-exploration-drilling-at-san-jose--e16776fa-164e-4fa8-91a1-0506ecdf7078#fact-drill-facts-0) San Jose · gold #### Identity - Hole ID: SJ01 - Project: San Jose - Commodity: gold - Ticker: MMN #### Geometry - Grade: 4.07 - Grade Unit: g/t - Intercept: 3 m #### Classification - Sample Type: drill - Group ID: SJ01:0-3.0 #### Review - Needs Review: No - Interp.

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.
