# Ivanhoe’s giant Makoko copper find gets 30% bigger Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/ivanhoe-s-giant-makoko-copper-find-gets-30-bigger--24e893a7-6684-44bc-b422-722554cd770d Original source: https://www.mining.com/ivanhoes-giant-makoko-copper-find-gets-30-bigger/ Publisher: miningcom Original announcement: 2026-09-08T13:15:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Ivanhoe Mines - Ticker: IVN - Exchange: Unavailable - Region: Democratic Republic of Congo - Primary commodity: Copper - Secondary commodities: None reported - Document categories: Resource update - Extracted: 2026-09-12 00:53:35 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Ivanhoe Mines has expanded its Makoko copper discovery by 30%, reaching approximately 12 million tonnes of contained copper. The updated resource includes 42 million tonnes of indicated resources at 2.66% copper and 612 million tonnes of inferred resources at 1.8% copper. Reasoning: The resource estimate shows substantial growth in contained copper and maintains high grades for the indicated category. - Positive factor: Significant tonnage growth \(30%\) - Positive factor: High-grade indicated resource \(2.66% Cu\) - Positive factor: Large scale of contained metal \(12 Mt Cu\) - Positive factor: Expansion of resource footprint Facts used in scoring: 2 ## Classification and evidence **Tonnage Growth** Polarity: positive Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved. Why it applies: The discovery expanded by 30% from its 2025 estimate. Evidence · text > expanding the giant discovery by 30% from its 2025 estimate **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The report explicitly states 42 million tonnes of indicated resources. Evidence · text > holds 42 million tonnes of indicated resources **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The report explicitly states 612 million tonnes of inferred resources.

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.
