# Blue Jay Gold Reports 67% Antimony Concentrate at 94% Recovery from Becker-Cochran: Concentrates Submitted for Metal Refining Tests Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/blue-jay-gold-reports-67-antimony-concentrate-at-94-recovery-from-becker-cochran--061838b4-44bf-41b0-9cb5-d428ad794e75 Original source: https://www.globenewswire.com/news-release/2026/09/21/3365421/0/en/blue-jay-gold-reports-67-antimony-concentrate-at-94-recovery-from-becker-cochran-concentrates-submitted-for-metal-refining-tests.html Publisher: globenewswire Original announcement: 2026-09-21T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-21T12:35:04.758Z Atlas analysis updated: 2026-09-21T12:35:04.758Z - Company: Blue Jay Gold Corp - Ticker: JAY - Exchange: Unavailable - Region: Yukon - Primary commodity: Antimony - Secondary commodities: Iron ore, Sulfur - Document categories: Metallurgy - Extracted: 2026-09-21 12:35:05 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Blue Jay Gold reported maiden metallurgical test results from the Becker-Cochran antimony occurrence at the Steller Project, producing a 66.9% Sb concentrate at 93.9% recovery. The concentrate has been submitted to three North American processing groups for refining tests to produce finished antimony products. Reasoning: Successful maiden flotation testwork producing high-grade antimony concentrate with strong recovery, though results are preliminary and lack variability testing. - Positive factor: High concentrate grade \(66.9% Sb\) exceeding premium thresholds - Positive factor: Strong recovery \(93.9%\) - Positive factor: Maiden test work successful - Positive factor: QA/QC disclosed with ALS lab and QP sign-off - Negative factor: Bench scale only \(preliminary\) - Negative factor: No variability studies completed - Negative factor: Mercury \(Hg\) noted in concentrate aliquot Facts used in scoring: 3 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: 93.9% Sb recovery is exceptional for a flotation process. Evidence · text > 94% Sb recovery **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Results are from laboratory-scale rougher-cleaner testing. Evidence · text > These results are based on laboratory-scale rougher-cleaner testing and are preliminary in nature **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: Release mentions ALS laboratory, internal QA/QC, and QP sign-off. Evidence · text > under documented chain of custody and modern quality assurance and quality controls **Deleterious Elements Present** Polarity: negative Story-specific tag Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release. Why it applies: Mercury \(Hg\) was noted in concentrate aliquot. Evidence · text > Hg in concentrate aliquot up 1,100 ppm **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a flotation route \("flotation"\) **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.
