# Spark Expands Arapaima’s Gallium–Rare Earth Portfolio with Boa Vista Surface Results Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/spark-expands-arapaima-s-gallium-rare-earth-portfolio-with-boa-vista-surface-res--cb4a55e7-f5e8-4495-bb36-a930f432d7b7 Original source: https://webfiles-primary.thecse.com/news_releases/en/4797/827b75bb-9678-4835-a906-f1b06a9afb15 Publisher: cse Original announcement: 2026-09-24T16:50:03.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-24T17:37:29.597Z Atlas analysis updated: 2026-09-24T17:37:29.597Z - Company: Spark Energy Minerals Inc. - Ticker: SPRK - Exchange: CSE - Region: Minas Gerais, Brazil - Primary commodity: Gallium - Secondary commodities: Rare earth, Scandium, Niobium, Neodymium praseodymium - Document categories: Drill results, Other - Extracted: 2026-09-24 17:37:30 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Spark Energy Minerals Inc. reported high-grade surface sampling results from its Boa Vista target at the Arapaima Project in Brazil, identifying it as a second mineralized center for gallium and rare earth elements. Soil samples returned up to 134.4 g/t Ga₂O₃, and stream sediments showed up to 1.0% TREO, with these results correlating well with previous near-surface drilling. The findings provide a strong foundation for follow-up exploration and drilling to define the extent and sources of mineralization. Reasoning: New high-grade surface sampling results for gallium and rare earth elements at the Boa Vista target expand the company's critical minerals portfolio and provide strong vectors for follow-up drilling, although these are early-stage exploration results. - Positive factor: High-grade gallium and rare earth results from surface samples - Positive factor: Identification of a second mineralized center \(Boa Vista\) - Positive factor: Surface geochemistry correlates with previous drilling - Positive factor: Guidance for future exploration and drilling - Positive factor: QA/QC disclosed - Negative factor: Surface samples are early-stage and not definitive - Negative factor: No new drill results reported in this release - Negative factor: No mineral resource or economic analysis yet - Negative factor: Scandium metallurgical recovery not demonstrated Low confidence — this extraction should be reviewed alongside the original source.
