# Spark Highlights Yttrium at Depth in Arapaima's Rare Earth System: 28 m at 200 ppm Y₂O₃ and 1,614 ppm Y₂O₃ in a Granite Grab Sample Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/spark-highlights-yttrium-at-depth-in-arapaima-s-rare-earth-system-28-m-at-200-pp--a075ce08-9923-4e4a-b81f-e66be5ae1707 Original source: https://webfiles-primary.thecse.com/news_releases/en/4797/9d23a75d-a579-4ded-9aa2-c6e057029bc3 Publisher: cse Original announcement: 2026-10-20T17:18:23.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-20T18:03:56.678Z Atlas analysis updated: 2026-10-20T18:03:56.678Z - Company: Spark Energy Minerals Inc. - Ticker: SPRK - Exchange: CSE - Region: Minas Gerais, Brazil - Primary commodity: Yttrium - Secondary commodities: Rare earth, Dysprosium, Terbium, Gallium - Document categories: Drill results - Extracted: 2026-10-20 18:03:57 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Spark Energy Minerals Inc. has released a yttrium-focused review of its Arapaima Project, highlighting significant yttrium grades from previously published drilling and newly disclosed surface samples. Key results include 28 meters at 200 ppm Y₂O₃ from drilling and a high-grade grab sample of 1,614 ppm Y₂O₃. The company interprets these results as indicating potential for deeper, rock-hosted rare earth mineralization, with yttrium being a critical mineral subject to Chinese export licensing. Reasoning: The company highlights significant yttrium grades from a review of prior drilling and new surface samples, emphasizing yttrium's critical mineral status and potential for deeper mineralization, despite the lack of new drilling and unknown true widths. - Positive factor: High-grade yttrium intercept \(1,614 ppm Y₂O₃ in grab sample\) - Positive factor: Significant yttrium grades over width \(28 m at 200 ppm Y₂O₃\) - Positive factor: Yttrium is a critical mineral with strategic importance - Positive factor: New surface sample results expand the dataset - Positive factor: Interpretation suggests potential for deeper, rock-hosted mineralization - Positive factor: QA/QC procedures are mentioned - Negative factor: Drill results are from a review of previously published drilling, not new drilling - Negative factor: True widths are not known - Negative factor: Mineral hosts for yttrium in granite are not identified - Negative factor: Grab samples are selective and not representative - Negative factor: Surface samples are geochemical indicators, not grades of mineralization - Negative factor: No economic significance should be attached to the ppm thresholds - Negative factor: No mineral resource or economic analysis has been completed Low confidence — this extraction should be reviewed alongside the original source.

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.
