# New metallurgical results add to Cannindah’s Copper lustre Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/new-metallurgical-results-add-to-cannindah-s-copper-lustre--3dcf3fe6-63ac-4cf7-9fbf-45bc916cf2ae Original source: https://stockhead.com.au/resources/new-metallurgical-results-add-to-cannindahs-copper-lustre/ Publisher: stockhead Original announcement: 2026-09-22T00:34:21.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Cannindah Resources - Ticker: CAE - Exchange: Unavailable - Region: Unavailable - Primary commodity: Copper - Secondary commodities: Silver, Gold - Document categories: Metallurgy, Resource update - Extracted: 2026-09-22 01:03:24 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Cannindah Resources has reported successful coarse particle flotation results at Mt Cannindah, achieving 94% copper and 92% silver recovery at a P80 of 450µm. These results suggest potential for lower energy costs and higher throughput, which will be incorporated into an upcoming Mineral Resource Estimate update. Reasoning: The announcement reports successful coarse particle flotation results that could significantly improve project economics via lower energy and higher throughput, while also providing a baseline resource for an upcoming update. - Positive factor: High copper recovery \(94%\) achieved at a significantly coarser grind \(P80 450µm\) - Positive factor: Coarse flotation allows for reduced energy requirements and potentially higher throughput - Positive factor: Conventional flotation confirmed saleable concentrate with low penalty elements - Positive factor: Strong mass rejection \(82%\) in coarse flotation - Negative factor: Gold recovery is variable and difficult to assay due to spotty distribution Facts used in scoring: 10 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The results involve flotation \(coarse and conventional\) which is a mill-based processing route. Evidence · text > coarse flotation test returned 94% copper recovery **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Copper recovery of 94% at a coarse grind is exceptional for this stage. Evidence · text > recovered 94% of copper and 92% of silver using NovaCell coarse particle flotation **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document explicitly mentions that new recovery assumptions will feed into a planned resource update. Evidence · text > New recovery assumptions will feed a resource update planned for the end of September **Gravity Route** Polarity: neutral Definition: Gravity separation forms a material part of the flowsheet. Why it applies: the document describes a gravity route \("gravity"\) **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.
