# Hannan Provides Update on First-Ever Drilling of Back-Arc Porphyry and Epithermal Targets in Peru Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/hannan-provides-update-on-first-ever-drilling-of-back-arc-porphyry-and-epitherma--1d95b596-43e6-4f76-98d9-ffc45c4848ed Original source: https://money.tmx.com/en/quote/HAN/news/7765923505499023/hannan-provides-update-on-first-ever-drilling-of-back-arc-porphyry-and-epitherma Publisher: tmx Original announcement: 2025-08-25T10:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Hannan Metals Limited - Ticker: HAN - Exchange: TSX - Region: Peru - Primary commodity: Gold - Secondary commodities: Copper, Molybdenum, Arsenic - Document categories: Drill results, Other - Extracted: 2026-08-25 14:51:55 UTC Narrative sentiment: 0.10 · Bullish ## Minestarters Atlas summary Hannan Metals has reported results from its first drilling at the Belen project in Peru, targeting both epithermal gold and porphyry Cu-Mo systems. While Vista Alegre holes intercepted only peripheral structures with surficial gold, the Ricardo Herrera hole \(HDDRH001\) has successfully intersected a porphyry system with visible chalcopyrite and molybdenite. Reasoning: The release reports pioneering first-pass drilling. While the epithermal target \(Vista Alegre\) missed the main structure, the porphyry target \(Ricardo Herrera\) shows encouraging visual mineralization and depth penetration, and the presence of high-grade boulders nearby provides significant exploration upside. - Positive factor: First-ever drilling of back-arc porphyry and epithermal systems - Positive factor: Visual mineralization \(chalcopyrite/molybdenite\) in HDDRH001 - Positive factor: High-grade gold boulders \(up to 2.72 g/t Au\) near Vista Alegre - Positive factor: Evidence of increasing fluid temperature at depth via SWIR - Negative factor: Vista Alegre holes failed to intersect main mineralized structure - Negative factor: Gold at Vista Alegre appears restricted to surficial regolith - Negative factor: High arsenic \(850 ppm\) noted in peripheral zones Facts used in scoring: 5 ## 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: Release mentions ALS Lima, standard sample preparation, and use of CRM and field duplicates. Evidence · text > Soil samples were analyzed by a portable XRF \(VANTA-VMR\) using an in-house protocol which includes routine use of CRM and field duplicates **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The drilling is described as the first-ever testing of these back-arc systems in this virgin territory. Evidence · text > representing the first-ever drill testing of these back-arc porphyry and epithermal systems ## Extracted facts Stored fact records: 5.
