# Chita South Porphyry \(PSU\) Drilling Results Received Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/chita-south-porphyry-psu-drilling-results-received--05098c20-f95a-4159-9221-b173c9079c03 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: 2026-08-25 23:07:13 UTC Narrative sentiment: 0.70 · 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 program, comprising infill and peripheral drilling, returned several long intercepts, notably including 270m at 0.20% Cu and 212 ppm Mo in PSUDH25-169, and a high-grade polymetallic vein in PSUDH25-162 with 3.1m at 4.66 g/t Au and 768.67 g/t Ag. The results confirm continuous mineralization and suggest potential extensions to the southwest. Reasoning: The drilling campaign at Chita South Porphyry delivered several long intercepts with strong molybdenum and moderate copper grades, including a bonanza-grade polymetallic vein. While some intercepts are lower grade, the overall results confirm and extend mineralization, with specific holes suggesting potential for new intrusion centers to the southwest. The company provided robust QA/QC and QP sign-off, enhancing confidence, though the lack of true width disclosure is a minor drawback. - Positive factor: High-grade polymetallic intercept - Positive factor: Long intercepts with strong molybdenum and moderate copper grades - Positive factor: Indication of potential extension and new intrusion centers - Positive factor: Comprehensive QA/QC disclosure and QP sign-off - Negative factor: True widths are unknown for all reported intercepts Facts used in scoring: 102 ## 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 explicitly mentions 'Quality Assurance/Quality Control' and details industry standard procedures, including the use of field duplicates, standards, and blanks. Evidence · text > Quality Assurance/Quality Control All core samples were cut and prepared on-site at the project area. The sample lengths were usually 2 m , except in areas with low recovery \(loss areas, faults, etc.\) and breaks from discrete principal geological features \(e.g., vein, vein breccia\). Drill core sizes of the drillholes included in this report are all HQ. Cutting was carried out by trained Miner Sud Argentina \(MSA\) personnel. Cores were split using the industry-standard Corewise automatic circular diamond blade rotary saw in the middle of the core, around 1 cm away from the core orientation mark. Half-core and duplicate samples, including all fragments, were placed in labelled plastic bags. Each had the sample number and was sealed using plastic security straps. 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. The analytical protocols are outlined as follows: ME-MS61 and ME-MS61m: Multitrace analyses of 48 elements with a 4-acid digestion. A prepared sample \(0.25 g\) is digested with perchloric, nitric, and hydrofluoric acids to dryness. The residue is taken up in a volume of 12.5 mL of 10 % hydrochloric acid. The resulting solution is analyzed by ICP-AES. Results are corrected for spectral interelement interference. ME-OG62: For samples over-limit, analysis is with four acid digestion using conventional ICPAES analysis for Ag, As, Cu, Mo, S, Pb, and Zn. Fire Assay Procedure Au-AA24 \(50g\): Gold is analyzed using a conventional fire assay fusion method with Atomic Absorption Spectroscopy \(AAS\). 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. MSA detected no significant QA/QC issues during review of the data. **QP/CP Signed** Polarity: positive Story-specific tag Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: The press release states that Dr Renato Bobis, MAusIMM CP \(Geo\) and VP-Exploration, is a qualified person as defined by Canadian National Instrument 43-101 and has approved the scientific and technical information. Evidence · text > 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 are unknown' for the reported intervals. Evidence · text > \(1\) the true thicknesses are unknown . **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', indicating a focus on increasing resource confidence. Evidence · text > in-fill and selective peripheral diamond drilling campaign **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drillholes PSUDH25-166 and PSUDH25-167 are described as suggesting the system is not closed off to the southwest and indicating another intrusion center, implying extension beyond known limits. Evidence · text > Drillhole PSUDH25-166 intersected increased Ag and Mo affecting the Aqua Negra sediments along the brecciated contact to a dacite porphyry intrusion, suggesting the system is not closed off to the southwest. 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. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Hole PSUDH25-162 intersected 3.1m at 4.66 g/t Au and 768.67 g/t Ag, which are exceptionally high grades for gold and silver, well above the typical thresholds for a porphyry deposit.

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.
