# U3O8 Corp.'s Test Work Simplifies Proposed Uranium-Vanadium Extraction from its Laguna Salada Deposit Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/u3o8-corp-s-test-work-simplifies-proposed-uranium-vanadium-extraction-from-its-l--c3621ae8-3d7f-46ec-94e7-f0afaf65db10 Original source: https://money.tmx.com/en/quote/GCOM/news/7992705768506141/u3o8-corp-s-test-work-simplifies-proposed-uranium-vanadium-extraction-from-its-l Publisher: tmx Original announcement: 2019-03-22T11:01:50.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: U3O8 Corp. - Ticker: UWE - Exchange: TSX - Region: Argentina - Primary commodity: Uranium - Secondary commodities: Vanadium - Document categories: Metallurgy - Extracted: 2026-09-12 07:57:59 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary U3O8 Corp. reported positive metallurgical test results for its Laguna Salada deposit in Argentina, demonstrating that a simplified process can remove 78% of gypsum \(sulphate\) using a coarse 0.85mm screen. This simplification is expected to reduce both capital and operating costs by eliminating expensive dewatering circuits and improving reagent efficiency. Reasoning: The test work demonstrates that a significantly simpler flowsheet can achieve comparable gypsum rejection to the complex process modeled in the PEA, directly addressing a major OPEX driver and reducing CAPEX requirements. - Positive factor: Process simplification potential - Positive factor: Reduction in capital cost \(CAPEX\) through elimination of dewatering circuits - Positive factor: High gypsum rejection \(78%\) using a much coarser screen \(0.85mm\) compared to previous PEA \(0.075mm\) - Positive factor: Significant impact on operating costs \(OPEX\) as sulphate removal is ~40% of PEA OPEX Facts used in scoring: 3 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The process involves screening, washing, and potentially leaching/separation. Evidence · text > washed with water in a rotating barrel **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: 3.

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.
