# Muntanga East Extends Heap Leach Case With Up to 86% Uranium Recovery Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/muntanga-east-extends-heap-leach-case-with-up-to-86-uranium-recovery--0fce4579-ac0e-4323-ae84-1ac6dd95e67e Original source: https://www.cruxinvestor.com/posts/muntanga-east-extends-heap-leach-case-with-up-to-86-uranium-recovery Publisher: cruxinvestor Original announcement: 2026-10-06T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-06T16:49:21.099Z Atlas analysis updated: 2026-10-06T16:49:21.099Z - Company: Atomic Eagle Limited - Ticker: AEU - Exchange: Unavailable - Region: Zambia - Primary commodity: Uranium - Secondary commodities: None reported - Document categories: Metallurgy - Extracted: 2026-10-06 16:49:21 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Atomic Eagle has completed metallurgical test work on the Muntanga East uranium deposit in Zambia, reporting uranium recoveries between 81% and 86% via bottle roll and column leach tests. The tests demonstrated low acid consumption and favorable physical characteristics for heap leach processing, supporting the economic viability of lower-grade material. Reasoning: Strong metallurgical results for a heap leach route on a new deposit \(Muntanga East\) which supports project scale and economics. - Positive factor: High uranium recoveries \(up to 86%\) - Positive factor: Low acid consumption \(approx 3 kg/t\) - Positive factor: Favorable heap leach characteristics \(low fines, high hydraulic conductivity\) - Positive factor: Enables economic recovery of lower-grade material Facts used in scoring: 4 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Uranium recoveries of up to 86% are achieved via heap leach route. Evidence · text > returned uranium recoveries of up to 86% at low acid use **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: The test work specifically targets heap leach processing. Evidence · text > extends the Muntanga heap leach case in Zambia. **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 2 distinct composites were tested ## 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.
