Spark Energy Minerals (SPARF) reported surface sampling results including 1.54% total rare earth oxides at Boa Vista, Brazil.
The peak soil sample contained 35.3% magnet rare earth oxides within total rare earth oxides (TREO). Forty of 81 Boa Vista soils exceeded 500 ppm TREO. Spark interprets the results as exposure of the rare earth zone previously intersected 20 to 32 m below surface in five maiden holes.
At undrilled Encachoeirado, a rock chip returned 137.1 g/t gallium oxide and 2,428 ppm TREO. Six of 65 stream-sediment samples exceeded 500 ppm TREO; none of 13 soil samples did. The highest stream-sediment result was isolated, and selective rock chips may not be representative.
Spark plans closer-spaced sampling and reverse circulation drilling at Boa Vista, plus trenching and channel sampling at Encachoeirado, subject to financing, field conditions, permits and access permissions.
Spark Energy Minerals (SPARF) disclosed yttrium results for 914 surface samples at its wholly owned Arapaima Project in Brazil. The review also compiles previously published drilling and road-cut assays; it contains no new drilling. At Cruzeta, hole ARA-RC-003 returned 28 m at 200 ppm yttrium oxide from 62 to 90 m and ended in mineralization at 94 m. A road-cut channel returned 22 m at 188 ppm. A selected granite grab sample returned 1,614 ppm, but is not representative of the granite or comparable to drill intervals.
New surface results include 507 ppm in a Boa Vista soil sample. Across the complete 1,038-sample surface dataset, 48 samples returned at least 100 ppm. Spark plans drilling beneath the road cut, subject to financing, and mineralogical and recovery testing. Yttrium host minerals remain unidentified, no yttrium test work has been reported, and no resource estimation has begun.
Spark Energy Minerals (SPARF) reported a Cruzeta granite grab sample containing 2.00% total rare earth oxides, identifying a second exploration target style. The hand-collected sample is not representative of the target or comparable with channel or drill results. Magnet rare earth oxides accounted for at least 36.0% of its total. Praseodymium exceeded the laboratory method’s limit; Spark expects a higher final value after additional analysis.
A 22 m horizontal channel averaged 2,392 ppm total rare earth oxides, with a 28.6% magnet rare earth share; a 4 m vertical channel averaged 1,725 ppm, with a 21.2% share. Surface sampling does not establish thickness or continuity. Spark plans drilling below the road cut and infill drilling, subject to financing. Nine completed holes await reporting after quality-control review. Separately, 750,000 immediately vested director stock options were granted at $0.05, exercisable for three years.
Spark Energy Minerals (SPARF) is nearing completion of initial prospecting at its Solonópole Project in Brazil, with SGS sample results pending. The property covers 15,691.24 hectares through eight exploration permits and one application, separate from its flagship Arapaima Project.
Spark plans to test whether regional geological trends extend to rare-metal pegmatites, coarse-grained rocks, on its ground. The broader program includes mapping and sampling for tantalum, beryllium and lithium, among other metals, plus interpretation of airborne radiometric data. Where warranted, trenching would precede drill planning.
No mineralization has been identified on Spark's permits, and no resource, reserve or economic assessment has been completed. Historic workings lie outside the permits. Public samples were not collected on Spark's ground, and the underlying public evidence remains unverified by the company.
Spark Energy Minerals (SPARF) reported Boa Vista surface assays on September 24, 2026, adding results from Brazil’s Arapaima Project.
At Boa Vista, 23 highlighted soil samples define a continuous anomalous zone approximately 2 km long; the highest returned 134.4 g/t gallium oxide. One stream-sediment sample returned 1.0% total rare earth oxides (TREO) and 2,178 ppm neodymium-praseodymium oxides. A rock-chip sample returned 1,331 ppm TREO and 59.1 g/t gallium oxide. The surface results helped guide drilling at Boa Vista, where five previously reported holes returned gallium and rare earth mineralization.
Spark plans closer-spaced soil sampling and further drilling to test the extent of mineralization. Arapaima has no estimated mineral resource or completed economic analysis. No recovery of gallium, scandium or rare earth elements has been demonstrated.
Spark Energy Minerals (SPARF) reported exploration, financing and corporate progress at its Brazilian projects since October 2025, led by new CEO Dr. Fernando Tallarico.
At the 100%-owned, 91,900-hectare Arapaima Project in Brazil’s Lithium Valley, 42 reverse circulation holes have been drilled, with 33 reported to date from the Cruzeta and Boa Vista targets. Every reported hole returned gallium and rare earth mineralization, including intervals up to 85 g/t Ga₂O₃ and 1.20% TREO at Cruzeta and 114.3 g/t Ga₂O₃ over 2 m and 28 m at 1,557 ppm TREO at Boa Vista. Assays from nine holes remain pending.
The company raised approximately $2.9 million between December 2025 and March 2026 to fund Arapaima drilling and working capital, strengthened its board and audit leadership, and initiated lithium work at Arapaima and Solonópole and tungsten reconnaissance at Seridó. Engagements with USTDA and the EU Critical Raw Materials Act are in process, with no funding, resource estimate, project recognition or feasibility study yet completed.
Spark Energy Minerals (SPARF) has begun reconnaissance tungsten exploration at its Seridó Project in Rio Grande do Norte, Brazil, across twelve permits totaling 21,492.74 hectares in five regional target areas beside producing and past-producing mines.
The work, started in September 2026, includes mapping marble and calc-silicate horizons, stream-sediment sampling, and rock-chip sampling with full QA/QC, targeting scheelite, the district’s tungsten ore mineral. Public geochemical data show the highest of 1,888 regional stream-sediment samples (122.3 ppm tungsten) located 1.6 km from permit 848.204/2023, with scheelite reported in the panned concentrate at that station. Tungsten prices rose about sixfold between January 2025 and April 2026 as China mined roughly 79% of global supply and introduced export licensing, while Spark positions Seridó as a tungsten addition to its gallium and rare earth focus at Arapaima.
Spark Energy Minerals (SPARF) has signed a five‑month digital marketing and investor awareness agreement with X Media Inc. SEZC, following two previously reported gallium–rare earth discoveries at its 91,900‑hectare Arapaima Project in Brazil. The campaign will run from September 10, 2026 to February 10, 2027 and will cover article distribution, email and SMS outreach, landing‑page development and paid digital advertising to broaden investor exposure to the Cruzeta and Boa Vista prospects.
Spark will pay X Media US$300,000 in cash, with no securities issued as compensation. Gallium and rare earth mineralization has been reported in all 33 RC holes disclosed to date at Cruzeta and Boa Vista, including an individual assay of 114.3 g/t gallium oxide over 2 metres at Boa Vista. Arapaima remains an exploration‑stage property with no mineral resources or reserves, and metallurgical recovery and economic viability have not been established.
Spark Energy Minerals (SPARF) appointed Marina Fagundes de Freitas as a non-executive director effective September 2, 2026, and named her Chair of the Audit Committee. The Board has determined that she is independent under National Instrument 52-110 Audit Committees.
Freitas is a finance executive with over twenty years of mining-sector experience in Brazil, including fifteen years at Jaguar Mining, where she ultimately served as Chief Financial Officer and previously held several senior finance, project and governance roles. She has also been Senior Advisor to Magna Mining. Her credentials include degrees in accounting, business administration and financial management, plus Certified Fraud Examiner, Certified Internal Auditor and Certification in Risk Management Assurance designations. Spark describes her appointment as strengthening the Board as the company advances its Arapaima critical minerals project in Minas Gerais, Brazil.
Spark Energy Minerals (CSE: SPRK, OTC: SPARF) reported a second gallium–rare earth discovery at the Boa Vista target within its 91,900-hectare Arapaima Project in Brazil’s Lithium Valley. Maiden drilling returned a project-record 114.3 g/t Ga₂O₃ over 2 m from surface in hole ARA-RC-007.
All five Boa Vista reverse-circulation holes intersected near-surface gallium and deeper rare earth mineralization, with mineralization remaining open in all directions. Highlights include 28 m at 1,557 ppm TREO, including 2 m at 3,459 ppm, in ARA-RC-031, plus surface scandium intervals up to 22 m at 17.7 g/t Sc₂O₃. According to Spark, Arapaima remains an exploration-stage property with no mineral resource, economic study or demonstrated metal recovery.
