# 98.2% Copper Recovery Settles B26's Flowsheet Question, Not Its Cost Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/98-2-copper-recovery-settles-b26-s-flowsheet-question-not-its-cost--58dc8315-f45a-4f15-af2c-ffc495269c45 Original source: https://www.cruxinvestor.com/posts/98-2-copper-recovery-settles-b26s-flowsheet-question-not-its-cost Publisher: cruxinvestor Original announcement: 2026-09-10T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Abitibi Metals - Ticker: AMQ - Exchange: Unavailable - Region: Quebec - Primary commodity: Copper - Secondary commodities: Gold, Silver, Zinc - Document categories: Metallurgy, Resource update - Extracted: 2026-09-10 15:03:52 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Abitibi Metals reported 98.2% copper recovery from flotation testwork on a representative composite from the B26 deposit in Quebec. While the results suggest a simple flotation circuit due to rapid kinetics and a coarse grind, the company cautions that final recoveries and capital costs are not yet determined. Reasoning: Strong initial copper flotation results from a more representative composite, though full flowsheet de-risking \(zinc and cleaning stages\) is incomplete. - Positive factor: High copper recovery \(98.2%\) - Positive factor: Rapid flotation kinetics suggesting simple circuit design - Positive factor: Coarse primary grind requirement - Positive factor: Larger/more representative composite than previous studies - Negative factor: Laboratory-scale results may not replicate at commercial scale - Negative factor: Rougher stage results may not represent final recoveries - Negative factor: Zinc, cleaner, and locked-cycle testing still outstanding - Negative factor: Cost/CapEx implications remain unquantified Facts used in scoring: 5 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: 98.2% copper recovery is exceptional for flotation Evidence · text > 98.2% copper recovery **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Results obtained using laboratory-scale equipment Evidence · text > Both came off laboratory-scale equipment rather than a plant. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a mill\_cil route \("CIL"\) **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 5.
