# Pinnacle Confirms High-Grade Mineralization in Underground Drilling at El Potrero with up to 58.2 g/t Au and 631 g/t Ag Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/pinnacle-confirms-high-grade-mineralization-in-underground-drilling-at-el-potrer--6af4ca63-2da1-4ff3-9445-6828c02404e6 Original source: https://orestocks.com/company/PINN.V/press-releases/6620011301482683 Publisher: orestocks Original announcement: 2026-09-09T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Pinnacle Silver and Gold Corp. - Ticker: PINN.V - Exchange: Unavailable - Region: Durango, Mexico - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Drill results - Extracted: 2026-09-09 11:58:33 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Pinnacle Silver and Gold Corp. has confirmed high-grade gold and silver mineralization at the El Potrero property in Mexico through underground drilling. Notable intercepts include up to 58.2 g/t Au and 631 g/t Ag, demonstrating continuity along the Dos de Mayo vein. Reasoning: The release reports high-grade gold and silver intercepts that confirm and extend previously known mineralization, supported by robust QA/QC disclosure. - Positive factor: high-grade intercepts - Positive factor: continuity of mineralization - Positive factor: QA/QC disclosed - Positive factor: epithermal deposit type - Negative factor: assays pending for several holes Facts used in scoring: 6 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Hole EPUG26068 returned 58.2 g/t Au and 631 g/t Ag over 0.41m, which is exceptionally high grade. Evidence · text > returned 58.2 g/t Au and 631 g/t Ag over 0.41 metres **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 QA/QC procedures including certified reference materials, blanks, and SGS laboratory accreditation. Evidence · text > including inserting certified reference material samples and blank samples into sample batches **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: The release mentions that chip channel samples are reasonably close to representing true widths, but does not provide a specific true width for the drill intercepts. Evidence · text > these samples are reasonably close to representing the true widths of the structures **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a mill\_cil route \("CIL"\) ## Extracted facts Stored fact records: 6.

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.
