# Chita South Porphyry \(PSU\) Drilling Results Received Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/chita-south-porphyry-psu-drilling-results-received--9a75d539-e428-4bf6-8aa3-2023d1fcf52b Original source: https://money.tmx.com/en/quote/MSR/news/6501500203303285/chita-south-porphyry-psu-drilling-results-received Publisher: tmx Original announcement: 2025-11-04T12:45:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Minsud Resources Corp. - Ticker: MSR - Exchange: TSX - Region: San Juan, Argentina - Primary commodity: Copper - Secondary commodities: Gold, Silver, Molybdenum - Document categories: Drill results - Extracted: 2026-09-18 11:09:55 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Minsud Resources Corp. announced assay results from 15 drillholes at its Chita South Porphyry \(PSU\) Cu-Mo-Au deposit in San Juan, Argentina. The infill and peripheral drilling campaign yielded several long intercepts of copper-molybdenum mineralization, with a notable high-grade polymetallic intercept in PSUDH25-162 \(3.1m at 4.66 g/t Au and 768.67 ppm Ag\). High molybdenum values in PSUDH25-167 suggest a potential new intrusion center, indicating exploration upside. The company provided detailed QA/QC disclosure, but true thicknesses and compositing cut-off grades were not stated. Reasoning: The document reports significant drill results from an infill and peripheral drilling campaign at the Chita South Porphyry project. Several holes show long intercepts of copper-molybdenum mineralization, with one hole \(PSUDH25-162\) hitting a high-grade polymetallic vein with exceptional gold and silver. The discovery of high molybdenum values in PSUDH25-167 suggests potential for a new intrusion center, adding exploration upside. The QA/QC procedures are well-documented, enhancing confidence in the results. However, the lack of true thickness disclosure and cut-off grades for compositing are notable omissions. - Positive factor: High-grade polymetallic intercept in PSUDH25-162 with significant gold and silver values - Positive factor: Long continuous intercepts of copper-molybdenum mineralization in several holes - Positive factor: Evidence of potential new intrusion center with high molybdenum values in PSUDH25-167 - Positive factor: Comprehensive QA/QC disclosure including certified labs and QP sign-off - Positive factor: Infill drilling confirms continuity and extends mineralization - Negative factor: True thicknesses are unknown for all reported intercepts - Negative factor: Cut-off grades for compositing are not disclosed - Negative factor: Some copper grades are relatively low for a porphyry deposit, though polymetallic nature adds value Facts used in scoring: 88 ## 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 includes detailed QA/QC disclosure, mentioning certified labs \(ISO 17025\), QP sign-off, and methods like field duplicates, standards, and blanks. Evidence · text > Quality Assurance/Quality Control All core samples were cut and prepared on-site at the project area. ... All core samples were submitted to the ALS Patagonia S.A. in Mendoza as the primary laboratory for sample preparation. This ISO 9001 accredited facility, with the prepared pulp samples sent to ALS Perú S.A. in Lima, Peru . The ALS Perú S.A. laboratory is accredited under ISO 9001:2008 and ISO 17025, ensuring compliance with international standards. ... MSA followed industry standard procedures for the work with a quality assurance/quality control \(QA/QC\) program. Field duplicates, standards and blanks were included with all sample shipments to the principal laboratory. ... Qualified Person \(QP\) Statement The scientific and technical information in this press release has been compiled, reviewed and approved by Dr Renato Bobis , MAusIMM CP \(Geo\), part-time VP-Exploration of the Company, and is a qualified person as defined by Canadian National Instrument 43-101. **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 the true thicknesses of the reported intervals are unknown. Evidence · text > \(1\) the true thicknesses are unknown . **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: The document reports significant assay results but does not state the cut-off grade used for compositing the intervals. Evidence · text > Table 2 : PSU In-fill Diamond Drilling Program – Significant Assay Results **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Drillhole PSUDH25-162 intersected 3.1m at 4.66 g/t Au and 768.67 ppm Ag, which are exceptionally high grades for gold and silver, especially in a porphyry setting. Evidence · table > 4.66 Context: 3.1 **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drillhole PSUDH25-167, the southwestern most drillhole, showed continuous high Mo values, suggesting another intrusion center and potential extension of mineralization. Evidence · text > Drillhole PSUDH25-167 intersected highly significant Mo values \(>100 ppm Mo\) from surface to the bottom of the drillhole, with up to 1502 ppm Mo. This is the southwestern most drillhole and progresses to the SW. The continuous high Mo values suggest another intrusion center and will be investigated further. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The drilling campaign is described as an 'in-fill and selective peripheral diamond drilling campaign'. Evidence · text > fifteen \(15\) additional drillholes completed in the recently finalized in-fill and selective peripheral diamond drilling campaign ## Extracted facts Stored fact records: 88.

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.
