Vancouver, British Columbia--(Newsfile Corp. - June 3, 2025) - Spark Energy Minerals Inc. (CSE: SPRK) (OTC Pink: SPARF) (FSE: 8PC) ("Spark" or the "Company") , is pleased to announce its participation as an Executive Dinner Sponsor and speaker in the 2^nd Annual Lithium and Critical Mineral Summit in Belo Horizonte, Minas Gerais, Brazil.

The Brazil Lithium & Critical Minerals Summit is a groundbreaking pioneer event taking place in Belo Horizonte on June 3rd - 5th 2025. Officially endorsed by Invest Minas, it stands as the exclusive platform in Brazil where the focus is on the burgeoning Lithium Valley. Gathering the most important industry players and international companies eyeing Brazil's lithium and critical mineral reserves, it'll be the sole platform offering direct engagement with the region's decision-makers.

Following the overwhelming success of the inaugural summit which gathered over 350 industry leaders from 25+ countries, featured more than 50 distinguished speakers, 40+ sponsors and partners, and facilitated over 180 private business meetings between C-Level executives, the 2025 summit will feature an expanded agenda, bringing together key government officials, investors, mining executives, and industry leaders from around the world.

Some notable attendees of this year's conference include Sigma Lithium, Pilbara Minerals, Lithium Ionic, European Investment Bank and Vale.

Spark Energy Minerals' CEO and Chair, Eugene Hodgson, together with Vice President of Exploration and Director, Jon Hill, will attend the Summit to engage with industry participants and discuss the Company's flagship Arapaima Lithium and Rare Earth Elements (REE) Project. Mr. Hill is also scheduled to present on the morning of June 4, 2025, providing a valuable opportunity to showcase Spark's project to an industry wide audience.

The Arapaima Lithium & REE project covers a combined land package of 919 km² and is a highly prospective early-stage exploration project with compelling lithium and REE potential.

Highlights

• Identification of 123 individual pegmatite occurrences across 13 trends with a combined strike length of 31 km.

• Discovery of anomalous lithium values in rock chip samples (up to 1,397 ppm Li) and stream sediments (up to 191 ppm Li), as well as evolved pegmatites with K/Rb ratios as low as 23.84, potentially indicative of spodumene-rich LCT pegmatites.
