# Gold Hart Copper Latest Diamond Drill Hole Returns Long Gold & Copper Porphyry-Style Mineralization Directly From Surface Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/gold-hart-copper-latest-diamond-drill-hole-returns-long-gold-copper-porphyry-sty--4a25ee99-b081-4057-a958-c60ea022317c Original source: https://www.newsfilecorp.com/release/316825/Gold-Hart-Copper-Latest-Diamond-Drill-Hole-Returns-Long-Gold-Copper-PorphyryStyle-Mineralization-Directly-From-Surface Publisher: newsfile Original announcement: 2026-10-01T11:36:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-01T12:17:59.515Z Atlas analysis updated: 2026-10-01T12:17:59.515Z - Company: Gold Hart Copper Corp. - Ticker: HART - Exchange: Unavailable - Region: Vicuna District, Chile - Primary commodity: Gold - Secondary commodities: Copper, Silver, Molybdenum - Document categories: Drill results, Other - Extracted: 2026-10-01 12:18:00 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Gold Hart Copper reported results from diamond drill hole DDHTOL04 at the Tolita project in Chile, featuring over 340m of gold-copper mineralization starting from surface. The company also provided updates on its application for the Copioso asset and reported high-grade trenching results from RC drilling. Reasoning: The drill hole DDHTOL04 returned significant continuous mineralization from surface, which is a key structural indicator for porphyry systems, although the grades are relatively low. - Positive factor: continuous mineralization from surface - Positive factor: long porphyry-style intercepts - Positive factor: high percentage of hole mineralized - Negative factor: low grades for porphyry style Facts used in scoring: 4 ## 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 certified lab \(AAA Labs\) and specific QA/QC protocols. Evidence · text > Certified lab conducting assays. Gold Hart utilized AAA Labs in Chile **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: Company positions assets adjacent to major miners like Escondida. Evidence · text > Gold Hart Copper is one of the largest independent land owners surrounding major miners ## Extracted facts Stored fact records: 4.

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.
