# Hercules Extends Copper Porphyry Discovery at Southern Flats Zone, Hercules Project, Idaho Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/hercules-extends-copper-porphyry-discovery-at-southern-flats-zone-hercules-proje--2f7eb36b-831d-44c8-8491-aa46f1ea5861 Original source: https://www.newsfilecorp.com/release/316699/Hercules-Extends-Copper-Porphyry-Discovery-at-Southern-Flats-Zone-Hercules-Project-Idaho Publisher: newsfile Original announcement: 2026-09-30T10:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-30T11:33:54.915Z Atlas analysis updated: 2026-09-30T11:33:54.915Z - Company: Hercules Metals Corp. - Ticker: BIG - Exchange: Unavailable - Region: Idaho - Primary commodity: Copper - Secondary commodities: Molybdenum, Silver, Gold - Document categories: Drill results, Other - Extracted: 2026-09-30 11:33:55 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Hercules Metals Corp. has reported significant step-out drill results from the Southern Flats zone of the Hercules Project in Idaho. Drill hole HER-26-01 intersected 287 m of 0.58% CuEq, extending the known copper porphyry mineralization and demonstrating strong vertical continuity. Reasoning: The 287m intercept of 0.58% CuEq represents a significant step-out extension of the Southern Flats zone, demonstrating the scale and continuity of the porphyry system. - Positive factor: significant step-out extension of porphyry mineralization - Positive factor: strong vertical continuity - Positive factor: presence of bornite mineralization suggesting enrichment potential - Positive factor: QA/QC disclosed with certified lab and QP sign-off - Negative factor: apparent width only \(true width not stated\) Facts used in scoring: 8 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: HER-26-01 is described as a 200 m step-out drill hole that has extended mineralization west of the Southern Flats discovery hole. Evidence · text > 200 m step-out drill hole HER-26-01 \(" 26-01 "\) has extended mineralization west of the Southern Flats discovery hole HER-25-25 **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 laboratory preparation, IMS-230 method, and the use of CRMs, blanks, and duplicates. Evidence · text > MSA Labs employs internal quality control standards, duplicates and blank samples at set frequencies. **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 insufficient data is available to state the true thickness of the mineralized intervals. Evidence · text > insufficient data are available at this time to state the true thickness of the mineralized intervals. ## Extracted facts Stored fact records: 8.
