Vancouver, British Columbia--(Newsfile Corp. - September 10, 2026) - Spark Energy Minerals Inc. (CSE: SPRK) (OTC Pink: SPARF) (FSE: 8PC) ("Spark" or the "Company") is expanding its investor outreach following two previously announced gallium-rare earth discoveries 7-8 kilometres apart at its approximately 91,900-hectare Arapaima Project in Brazil's Lithium Valley. To bring the exploration progress at Cruzeta and Boa Vista to a broader audience, the Company has signed a five-month digital marketing services agreement with X Media Inc. SEZC ("X Media").

Gallium and Rare Earth Mineralization in Every Drill Hole Reported to Date

Spark has reported gallium and rare earth mineralization in all 33 RC drill holes disclosed to date across Cruzeta and Boa Vista, underscoring the consistency of results at the two separate discoveries. The Company has completed 42 RC holes across Arapaima, with results from the remaining nine holes yet to be reported.

In its August 27, 2026 news release, Spark reported a project-record individual gallium assay of 114.3 g/t gallium oxide (Ga₂O₃) over 2 metres from surface in hole ARA-RC-007 at Boa Vista. All five maiden Boa Vista holes returned gallium mineralization from surface and rare earth mineralization below.

"We believe now is the time to put Spark in front of a much larger investor audience, given the compelling exploration results to date," said Dr. Fernando Tallarico, Chief Executive Officer of Spark. "We are bringing X Media on board to expand our reach and tell the Arapaima discovery story with greater impact. Our exploration progress deserves broader attention, and we are taking a deliberate step to get that story heard."

Previously Reported Technical Information

The exploration information summarized above was previously reported in Spark's news releases, including its August 27, 2026 release, available at www.sparkminerals.co. Readers should refer to the original releases for complete results, sampling and analytical procedures, QA/QC and data verification. The 114.3 g/t Ga₂O₃ result is an individual 2-metre in-situ assay, not a composite or a measure of recoverable gallium. Reported intervals are down-hole widths; true widths are unknown. Individual high-grade values are not necessarily representative, and the results do not establish continuity between Cruzeta and Boa Vista.

Arapaima is an exploration-stage property with no estimated mineral resource or reserve. Metallurgical recovery and economic viability have not been established.
