Spark Announces Completion of Maiden Drill Campaign in Brazil’s Lithium Valley
VANCOUVER, BC, February 10, 2026 – Spark Energy Minerals Inc. (CSE: SPRK) (OTC: SPARF) (Frankfurt: 8PC) ("Spark" or the "Company") reports the first assay results from holes ARA-RC-001 through ARA-RC-003 of its maiden five-hole reverse circulation ("RC") program at the Arapaima Project in Brazil’s Lithium Valley. The table below summarizes the NI 43-101 disclosure for each highlighted interval, including Hole ID, from/to, interval, oxide grade, and associated gallium assays. Assays for holes ARA-RC-004 and ARA-RC-005 remain pending and will be reported once received.
Highlights
Hole ARA-RC-003 intersects 78 m grading 2,430 ppm TREO from 16 m, including 10 m at 4,522 ppm TREO from 50 m and 2 m at 6,682 ppm TREO from 70 m, with a continuous 94 m zone grading 63 g/t Ga2O3 from surface.
Hole ARA-RC-001 returns 28 m grading 2,031 ppm TREO from 30 m, including higher-grade lenses such as 2 m at 4,741 ppm TREO from 46 m and 6 m at 2,663 ppm TREO from 48 m, plus a 58 m Ga zone at 52 g/t Ga2O3 from surface.
Hole ARA-RC-002 provides a 16 m interval grading 1,353 ppm TREO from 26 m, hosting 2 m at 2,244 ppm TREO from 30 m and 2 m at 2,075 ppm TREO from 38 m, alongside a 44 m Ga interval starting at surface that grades 47 g/t Ga2O3.
Geological Interpretation
The mineralization occurs within thick, clay-rich weathering profiles consistent with an ionic-adsorption clay (IAC)-style system. RC drilling encountered gallium-rich saprolite from surface with magnet rare-earth-bearing zones at depth, supporting the interpretation of a vertically developed, laterally extensive mineralized footprint. Modeling will continue as assays for ARA-RC-004 and ARA-RC-005 arrive to provide additional context on the lateral extension.
Drill Hole Disclosure Table
All samples were collected in two-metre intervals, quartered with a Jones splitter, and approximately 2 kg submitted to SGS Geosol Ltda. (ISO 9001 and ISO 14001 certified) for analysis. QA/QC protocols included one blank per batch, certified reference materials every 15 samples, and duplicates every 20 samples. Collars, azimuths, and depth details are documented in Spark’s internal assay database and will be appended to the subsequent technical disclosure release once assay results are ready.
QA/QC and Laboratory Procedures
Samples were collected in 2-metre intervals, quartered with a Jones splitter, and approximately 2 kg per sample submitted to SGS Geosol Ltda. (ISO 9001-2015, ISO 14001-2015). Each hole batch included a blank at the start, a certified reference material every 15 samples, and duplicate splits every 20 samples. SGS Geosol performed sodium peroxide fusion ICP-MS/OES analyses (code ICM90A) for 56 elements, including the full rare-earth suite, lithium, and gallium. Sample preparation included crushing 75% <3 mm and pulverizing 250 g to 95% <150# under code PRP70J_A2-PA. The QA/QC logs accompany the table attached to this release.
Regional Setting and Pipeline
The Arapaima Project sits within Brazil’s expanding Lithium Valley in northern Minas Gerais, a region recognized for lithium, gallium, and rare-earth potential. Spark controls approximately 91,900 hectares of contiguous tenure, providing optionality to expand the mineralized footprint and to follow up on four additional drill-ready lithium pegmatite targets as part of a multi-staged exploration effort.

Forward-looking information includes, but is not limited to, statements regarding the interpretation of exploration results, the potential significance, continuity, extent, and grade of mineralization encountered, the identification and potential implications of an ionic-adsorption clay (“IAC”)–style system, the potential for future exploration and drilling programs, the advancement of the Arapaima Project, the evaluation of additional targets within the Company’s land package, the availability of financing, and the Company’s future plans, objectives, and strategies.
Forward-looking information is generally identified by the use of forward-looking terminology such as “may,” “could,” “expect,” “intend,” “believe,” “will,” “projected,” “estimated,” “anticipates,” or similar expressions, or statements that certain events or conditions “may,” “could,” or “will” occur. Such statements are based on the Company’s current expectations, assumptions, and beliefs, including assumptions regarding geological interpretations, exploration results, continuity of mineralization, metallurgical characteristics, market conditions, access to capital, and regulatory approvals.
Actual results may differ materially from those expressed or implied by such forward-looking information due to a variety of risks and uncertainties, including, but not limited to, geological uncertainty, the inherently preliminary nature of exploration results, the selective nature of rock, soil, and drill samples, the possibility that future exploration results may not be consistent with expectations, changes in market conditions, availability of financing, and risks associated with mineral exploration and development.
