# 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--a84bd6dd-b05c-43cf-8ecd-c2bb23030cf7 Original source: https://www.newsfilecorp.com/release/319891/Spark-Highlights-Yttrium-at-Depth-in-Arapaimas-Rare-Earth-System-28-m-at-200-ppm-Y2O3-and-1614-ppm-Y2O3-in-a-Granite-Grab-Sample Publisher: newsfile Original announcement: 2026-10-20T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-20T12:20:42.822Z Atlas analysis updated: 2026-10-20T12:20:42.822Z - Company: Spark Energy Minerals Inc. - Ticker: SPRK - Exchange: Unavailable - Region: Minas Gerais, Brazil - Primary commodity: Yttrium - Secondary commodities: Rare earth elements, Dysprosium, Terbium - Document categories: Drill results - Extracted: 2026-10-20 12:20:43 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Spark Energy Minerals Inc. announced new yttrium results from its Arapaima Project in Brazil, highlighting significant grades in both drill intercepts and surface samples. The results include 28 meters at 200 ppm Y2O3 from 62 meters depth in drill hole ARA-RC-003 and a high-grade granite grab sample of 1,614 ppm Y2O3. This data suggests a deeper, rock-hosted style of yttrium mineralization, a critical mineral with strategic importance, though true widths are unknown and the project remains at an early exploration stage. Reasoning: The release highlights significant yttrium grades in both drill intercepts and surface samples, including a very high-grade grab sample, and suggests a deeper, rock-hosted mineralization style for a critical mineral, despite the early exploration stage and unknown true widths. The strategic importance of yttrium as a critical mineral adds to the positive outlook. - Positive factor: High-grade yttrium in grab sample \(1,614 ppm Y2O3\) - Positive factor: Significant yttrium intercepts at depth in drill holes \(e.g., 28 m at 200 ppm Y2O3\) - Positive factor: Yttrium identified in weathered granite, suggesting a deeper, rock-hosted style of mineralization - Positive factor: First-time reporting of yttrium results for a large number of surface samples - Positive factor: Yttrium is a critical mineral with strategic importance - Positive factor: Correlation of yttrium with heavy rare earths \(dysprosium, terbium\) - Negative factor: True widths are not known for drill intercepts - Negative factor: No mineral resource estimate or economic analysis has been completed - Negative factor: Yttrium host minerals in granite not yet identified - Negative factor: Grab samples are selective and not representative - Negative factor: Surface samples are geochemical indicators, not grades of mineralization - Negative factor: QA/QC for surface samples relies on lab's internal program, not company's full QA/QC - Negative factor: The 50 and 100 ppm thresholds are geochemical criteria, not economic cut-off grades Facts used in scoring: 106 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 106.

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.
