# Golden Arrow Files Technical Report for San Pietro Copper-Gold-Iron-Cobalt Project, Chile Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/golden-arrow-files-technical-report-for-san-pietro-copper-gold-iron-cobalt-proje--4d1be562-3324-45d9-9449-e90631ee277c Original source: https://money.tmx.com/en/quote/GRG/news/5470008111576612/golden-arrow-files-technical-report-for-san-pietro-copper-gold-iron-cobalt-proje Publisher: tmx Original announcement: 2025-04-03T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Golden Arrow Resources Corporation - Ticker: GRG - Exchange: TSX - Region: Atacama Region, Chile - Primary commodity: Copper - Secondary commodities: Gold, Cobalt, Iron ore - Document categories: Resource update - Extracted: 2026-09-16 03:20:16 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Golden Arrow Resources has filed a NI 43-101 Technical Report disclosing the first mineral resource estimate for the San Pietro Project in Chile. The maiden estimate comprises 492 Mt of Inferred resources at 0.41% CuEq, including significant copper, gold, cobalt, and iron components. Reasoning: The announcement of a maiden mineral resource estimate for a large-scale IOCG project is a major milestone, though the lack of Indicated/Measured resources limits immediate project valuation. - Positive factor: Maiden resource estimate established - Positive factor: Significant scale with 492 Mt total inferred resource - Positive factor: Multi-commodity potential \(Cu-Au-Co-Fe\) - Negative factor: 100% Inferred category implies high geological risk - Negative factor: No economic viability demonstrated \(not a reserve\) Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 12 ## Classification and evidence **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable. Why it applies: The announcement discloses the first mineral resource estimate for the San Pietro Project. Evidence · text > supporting disclosure of the first mineral resource estimate \("MRE"\) **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: 100% of the reported mineral resource is in the Inferred category. Evidence · table > Inferred Context: Oxide **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource estimate was prepared in accordance with NI 43-101 standards. Evidence · text > conform to NI 43-101 standards and guidelines **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: Qualified Persons Susan Lomas and Dr. Bruce Davis are named as responsible for the report. Evidence · text > Qualified Persons: Susan Lomas , P.Geo. & Dr. Bruce Davis , PhD, FAusIMM **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: The cut-off grade for reporting the mineral resources is clearly stated as 0.30% CuEq. Evidence · text > The cut-off grade for reporting the mineral resources within the pitshell is 0.30% CuEq ## Extracted facts Stored fact records: 12.

Evidence · table > 14.43 Context: 492 #### Tags used in scoring **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: category is "inferred" **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: cutoff\_grade is stated **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: qp\_signed is true **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

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.
