Preliminary metallurgical testing showed strong copper recoveries of 92.6% and favorable mineral liberation. Reasoning: The announcement reports the completion of a drilling campaign and provides encouraging preliminary metallurgical results, though the full assay data for the new holes is not yet available. - Positive factor: Successful completion of 2025 drilling campaign - Positive factor: Favorable geometallurgical results \(high Cu liberation, low pyrite\) - Positive factor: Strong copper recovery \(92.6%\) in rougher flotation - Positive factor: Progress towards 2025 PEA - Negative factor: Full assay results for the campaign are still pending \(only 20% received\) Facts used in scoring: 2 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release includes a Qualified Person \(QP\) sign-off by Mr. José Luis Bello Soto. Evidence · text > The scientific and technical content of this news release has been reviewed and approved by Mr. José Luis Soto **Free Milling** Polarity: positive Definition: Simple, clean ore amenable to standard processing without oxidation. Why it applies: Mineralogical results indicate high chalcopyrite liberation and low pyrite association. Evidence · text > high liberation and low association with pyrite \(Py\) **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: Tests support the design of a conventional grinding circuit. Evidence · text > supporting the design of a conventional grinding circuit **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: 2. Some facts used in scoring do not have a stored record. ## Metallurgical Results (2) ### rougher flotation [Link to this fact](https://atlas-extractions.minestarters.com/news/tintina-mines-completes-drilling-campaign-and-reports-key-geometallurgical-advan--674b26a0-013a-4eed-8473-5e8e85b17df4#fact-metallurgical-facts-0) Domeyko Sulfuros Project · copper #### Identity - Project: Domeyko Sulfuros Project - Commodity: copper - Region: chile - Reported Region: Atacama Region, Chile - Ticker: TTS #### Test Work - Program Status: preliminary - Test Type: rougher flotation - Processing Route: rougher flotation - Sample: five-stage kinetic tests #### Recovery - Recovery: 92.6 % - Recovery Basis: actual\_test #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2025-08-18T00:00:00.000Z Reasoning: 92.6% Cu recovery in flotation is a strong technical result. - Positive factor: Recovery is in the exceptional band for copper flotation Evidence · text > five-stage kinetic tests yielded average recoveries of 92.6% Cu #### Tags used in scoring **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: processing\_route matches the flotation signal **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: 92.6% is at or above the exceptional band \(92%\) ### rougher flotation [Link to this fact](https://atlas-extractions.minestarters.com/news/tintina-mines-completes-drilling-campaign-and-reports-key-geometallurgical-advan--674b26a0-013a-4eed-8473-5e8e85b17df4#fact-metallurgical-facts-1) Domeyko Sulfuros Project · gold #### Identity - Project: Domeyko Sulfuros Project - Commodity: gold - Region: chile - Reported Region: Atacama Region, Chile - Ticker: TTS #### Test Work - Program Status: preliminary - Test Type: rougher flotation - Processing Route: rougher flotation - Sample: five-stage kinetic tests #### Recovery - Recovery: 74.9 % - Recovery Basis: actual\_test #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2025-08-18T00:00:00.000Z Reasoning: 74.9% Au recovery is a reasonable result for a flotation-based circuit. - Positive factor: Solid gold recovery for a flotation circuit Evidence · text > 74.9% Au at P80 = 150 µm #### Tags used in scoring **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: processing\_route matches the flotation signal **Low Recovery** Polarity: negative Definition: Recovery below the weak band for the commodity and processing route. Why it applies: 74.9% is below the weak band \(80%\) ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
