# Regulus Reports Positive Nuton\(TM\) Technologies Extraction Rates on AntaKori Mineralization From Phase One Program Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/regulus-reports-positive-nuton-tm-technologies-extraction-rates-on-antakori-mine--43741e39-10f9-411a-9d10-cda88d0e0bb5 Original source: https://money.tmx.com/en/quote/REG/news/5017213556026050/regulus-reports-positive-nuton-tm-technologies-extraction-rates-on-antakori-mine Publisher: tmx Original announcement: 2023-07-06T12:50:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Regulus Resources Inc. - Ticker: REG - Exchange: TSX - Region: Peru - Primary commodity: Copper - Secondary commodities: Gold, Silver - Document categories: Metallurgy - Extracted: 2026-09-16 19:21:14 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Regulus Resources Inc. has reported positive copper extraction rates of up to 95% using Nuton's proprietary sulphide leach technology on AntaKori mineralization. The phase one shaker flask testing covered high sulphidation, skarn, and breccia/porphyry styles, prompting the definition of a phase two column testing program. Reasoning: The announcement reports successful preliminary copper extraction rates using proprietary technology, providing a technical de-risking signal for the AntaKori project, though results are currently limited to small-scale laboratory tests. - Positive factor: High copper extraction rates \(up to 95%\) - Positive factor: Successful phase one shaker flask testing - Positive factor: Clear pathway to phase two column testing - Positive factor: Strategic partnership with Nuton \(Rio Tinto venture\) - Negative factor: Small scale shaker flask tests may not predict commercial scale results - Negative factor: Testing limited to specific mineralization styles 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 flowsheet is described as a bio-heap leach flowsheet involving crushed and agglomerated feed. Evidence · text > The Nuton flowsheet is a conventional crushed and agglomerated feed, bio-heap leach flow sheet **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Phase one results were obtained using small scale shaker flask tests. Evidence · text > This round of test work utilized relatively small samples and was completed in shaker flasks. **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release names a Qualified Person \(Dr. Kevin B. Heather\) who reviewed and approved the technical data. Evidence · text > The scientific and technical data contained in this news release pertaining to the AntaKori project has been reviewed and approved by Dr. Kevin B. Heather **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: the document describes a heap\_leach route \("heap leach"\) **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 3 distinct composites were 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.
