# Pacific Ridge Announces Filing of NI 43-101 Technical Report for Kliyul Copper-Gold Project Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/pacific-ridge-announces-filing-of-ni-43-101-technical-report-for-kliyul-copper-g--1e08faf1-a71b-4210-90ab-7b59ef7a57c4 Original source: https://money.tmx.com/en/quote/PEX/news/5644457001254367/pacific-ridge-announces-filing-of-ni-43-101-technical-report-for-kliyul-copper-g Publisher: tmx Original announcement: 2025-09-18T20:31:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Pacific Ridge Exploration Ltd. - Ticker: PEX - Exchange: TSX - Region: British Columbia - Primary commodity: Copper - Secondary commodities: Gold, Silver - Document categories: Resource update - Extracted: 2026-08-21 06:53:02 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Pacific Ridge Exploration Ltd. has filed an NI 43-101 technical report for the Kliyul copper-gold project, announcing a maiden Inferred Mineral Resource for the Kliyul Main Zone. The resource comprises 334.1 million tonnes at 0.33% CuEq, containing significant copper, gold, and silver metal content. Reasoning: The company filed its initial NI 43-101 technical report establishing a maiden Inferred resource of 334.1 Mt at 0.33% CuEq. While the scale is significant, the lack of measured/indicated resources and metallurgical validation limits immediate economic confidence. - Positive factor: Maiden resource establishment - Positive factor: Large scale tonnage - Positive factor: Porphyry target continuity - Negative factor: 100% Inferred category - Negative factor: No metallurgical testing performed Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 4 ## Classification and evidence **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: The report supports the initial mineral resource estimate for the Kliyul Main Zone. Evidence · text > in support of the initial mineral resource estimate \("MRE"\) for the Kliyul Main Zone \("KMZ"\) **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The entire resource reported for KMZ is in the Inferred category. Evidence · text > in the Inferred Mineral Resource category **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The technical report was prepared in accordance with NI 43-101 standards. Evidence · text > prepared in accordance with National Instrument 43-101 **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: Independent Qualified Persons Susan Lomas, P.Geo. and Bruce Davis, PhD, FAusIMM are named. Evidence · text > completed by Susan Lomas, P.Geo. of Lions Gate Geological Consulting Inc. with assistance from Bruce Davis, PhD, FAusIMM ## 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.
