# San Lorenzo Reports Final Assay Results from Hole SAL 10-25 with Drilling Ending in Porphyry Style Mineralization at the Arco de Oro Target Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/san-lorenzo-reports-final-assay-results-from-hole-sal-10-25-with-drilling-ending--b306f6ed-14f4-4c2a-8824-2886fc950eb2 Original source: https://money.tmx.com/en/quote/SLG/news/6938381992030060/san-lorenzo-reports-final-assay-results-from-hole-sal-10-25-with-drilling-ending Publisher: tmx Original announcement: 2026-06-04T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: San Lorenzo Gold Corp. - Ticker: SLG - Exchange: TSX - Region: Unavailable - Primary commodity: Gold - Secondary commodities: Silver, Copper - Document categories: Drill results - Extracted: 2026-09-16 22:44:16 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary San Lorenzo Gold Corp. reports final assay results from hole SAL 10-25 at the Arco de Oro target, part of its Salvadora property. The drilling, a 3.9 km step-out, intersected significant gold mineralization, including 102.3 metres at 1.33 g/t gold and 52.6 metres at 1.67 g/t gold, with mineralization continuing to the bottom of the 574-metre hole in porphyry style. The company notes that results below 348 metres are newly received, while shallower intercepts were previously reported. Reasoning: The document reports significant gold and copper intercepts from step-out drilling at the Arco de Oro target, with mineralization continuing to the bottom of the hole in porphyry style. This indicates potential for a large system, although true widths are not yet known and some results are historical. - Positive factor: Significant gold intercepts, particularly the 102.3m at 1.33 g/t Au and 52.6m at 1.67 g/t Au, with several high-grade sub-intervals. - Positive factor: Drilling ended in porphyry-style mineralization, suggesting potential for a larger, deeper system. - Positive factor: Step-out drilling successfully extended mineralization and confirmed a significant IP anomaly. - Positive factor: QP sign-off and certified lab disclosure provide confidence in assay results. - Negative factor: True width of intercepts is unknown, which may overstate actual thickness. - Negative factor: Some results are re-reported historical data, reducing novelty for those specific intervals. - Negative factor: Assay turnaround times are frustrating, delaying full program results. Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 120 ## Classification and evidence **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 company states that the correlation between sample intervals and true widths are unknown. Evidence · text > San Lorenzo notes that the correlation between sample intervals and true widths are unknown as the systems are still being modeled. **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 details sample preparation, assay methods by ALS Laboratories, and QP review. Evidence · text > The scientific and technical information contained in this news release has been reviewed and approved by Terence Walker, M.Sc., P. Geo., the VP of Exploration of San Lorenzo who is a "qualified person" within the meaning of National Instrument 43-101. Testing Procedures Samples consisting of 50% of the HQ core are delivered to the ALS Laboratories in Copiapó by San Lorenzo staff for preparation which consists of drying and crushing to a 2 mm mesh and then pulverized. The sample material is then delivered to ALS’s facilities in Lima, Peru for gold analysis using the fire assay method. Samples were also analyzed by aqua-regia digestion to analyze for other elements including Ag and Cu. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Hole SAL 10-25 was a 3.9 km step-out from previous core-zone drilling, extending the known mineralization. Evidence · text > Hole SAL 10-25 \(and Hole SAL 09-25\) were 3.9 km step-outs from San Lorenzo’s previous “core-zone” drilling at Arco de Oro. ## Extracted facts Stored fact records: 120.

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.
