# Pinnacle Provides First Results from Underground Drilling Program at El Potrero; Samples up to 59.2 g/t Au and 424 g/t Ag with Visible Gold Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/pinnacle-provides-first-results-from-underground-drilling-program-at-el-potrero--bfe3688d-37a4-495c-b7cd-ca8df8905139 Original source: https://money.tmx.com/en/quote/PINN/news/7447741004111632/pinnacle-provides-first-results-from-underground-drilling-program-at-el-potrero- Publisher: tmx Original announcement: 2026-08-18T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Pinnacle Silver and Gold Corp. - Ticker: PINN - Exchange: TSX - Region: Durango, Mexico - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Drill results - Extracted: 2026-09-12 18:31:57 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Pinnacle Silver and Gold Corp. announced initial results from its underground drilling program at the El Potrero gold-silver property in Durango, Mexico, revealing high-grade intercepts up to 59.2 g/t Au and 424 g/t Ag over 1.07 meters, with visible gold observed. The program successfully extended the known strike length of the Pinos Cuates mineralized zone to at least 70 meters. While the results are encouraging and supported by disclosed QA/QC, the company noted challenges with poor core recovery in some holes and difficulty in calculating true widths for certain along-strike intercepts. Reasoning: The first results from the underground drilling program at El Potrero delivered exceptional gold and strong silver grades, including a bonanza intercept with visible gold, significantly extending the known mineralization. However, concerns regarding core recovery and true width determination for some intercepts temper the overall confidence. - Positive factor: Bonanza gold intercept \(59.2 g/t Au\) with visible gold - Positive factor: Significant silver grades \(up to 424 g/t Ag\) - Positive factor: Extension of known strike length by 20 meters to the northwest and 21 meters to the southeast - Positive factor: Detailed QA/QC procedures disclosed, including accredited lab and QP sign-off - Negative factor: Poor core recovery in some holes \(locally averaging as low as 20%\) - Negative factor: True width difficult to calculate for several key intercepts due to drilling angle along strike - Negative factor: Cut-off grade for compositing of reported intervals is not disclosed Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 48 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The intercept of 59.2 g/t Au over 1.07 meters is exceptionally high-grade, well above the underground gold threshold of 15 g/t. Evidence · text > 59.2 grams per tonne gold \(g/t Au\) and 424 grams per tonne silver \(g/t Ag\) over 1.07 metres, where fine grained visible gold was observed **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 a detailed QA/QC section mentioning NI 43-101 compliance, certified reference materials, blank samples, an ISO/IEC 17025:2017 accredited SGS laboratory, and QP sign-off. Evidence · text > The technical results contained in this news release have been reported in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects \(“NI 43-101”\). Pinnacle has implemented industry standard practices for sample preparation, security and analysis given the stage of the Project. This has included common industry QA/QC procedures to monitor the quality of the assay database, including inserting certified reference material samples and blank samples into sample batches on a predetermined frequency basis. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling extended the known strike length of mineralization to the northwest by approximately 20 meters and to the southeast by up to 21 meters. Evidence · text > extended the known strike length of the mineralization to the northwest by approximately 20 metres... while the southeast strike extent was extended with assays returning up to 9.54 g/t Au and 134 g/t Ag over 1.5 metres **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: Several intercepts are reported with 'Along strike' for estimated true width, and the company notes difficulty in calculating actual width for a key horizontal hole drilled at a shallow angle to the vein. Evidence · text > While this makes it difficult to calculate the actual width of the mineralized zone in this hole, it was confirmed that there is good mineralization for at least the next 20 metres along strike in that direction. **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: The release does not state the cut-off grade used for compositing the reported drill intervals. Evidence · text > Sample intervals vary from 0.2 to 1.5 metres in length for HQ core, and from 0.35 to 1.5 metres for NQ cores, with samples being selected to honour geological contacts. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The program comprises more than 100 short, closely spaced holes from within historic mine workings to better understand the size, shape and average grade of the mineralized zones, indicating a resource definition objective. Evidence · text > the program comprises more than 100 short, closely spaced holes from with the historic mine workings to better understand the size, shape and average grade of the mineralized zones. **Poor Core Recovery** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The document explicitly states that oxidation and fracturing resulted in very poor core recoveries in some holes, locally averaging as low as 20%. Evidence · text > oxidation and fracturing of the rock resulted in very poor core recoveries in some holes, locally averaging as low as 20%. ## Extracted facts Stored fact records: 48.

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.
