[{"type":"text","content":" Vancouver, British Columbia--(Newsfile Corp. - June 20, 2025) - Spark Energy Minerals Inc. (CSE: SPRK) (OTC Pink: SPARF) (FSE: 8PC) (\"Spark\" or the \"Company\"), is pleased to provide an update on ongoing exploration at its flagship Arapaima Project in Brazil's Lithium Valley. Positive assay results from 16 rock-chip and 46 stream-sediment samples, recently received from SGS Laboratories in Belo Horizonte, reinforce Spark Energy's focus on advancing its three priority lithium targets-Cruzeta, Água Branca, and Grota do Maquém-toward diamond drilling in Q3 2025. The Company is also progressing its emerging REE target at Caladão. Figure 1. Location of Spark Energy Minerals Arapaima Project Tenements in Brazil's Lithium Valley relative to competitor areas (left) and the location of the Company's priority lithium and REE targets (right image). \"These results further validate the strong lithium potential of our Arapaima Project,\" commented Spark's CEO, Eugene Hodgson. \"The 3,712 ppm lithium-in-rock result at Cruzeta is our highest to date, supported by key pathfinder elements indicative of evolved LCT pegmatites. The 118 ppm lithium in stream sediments at Água Branca further underscores the district-scale opportunity. \"With diamond drilling planned for Q3 2025, we are accelerating target refinement. Brazil's Lithium Valley is quickly emerging as a globally significant jurisdiction for critical minerals, and Spark is well-positioned at the forefront of this discovery phase.\" Cruzeta Target Rock-Chip Results Spark Energy reports encouraging reconnaissance rock-chip sample results for 16 samples collected from pegmatite exposures at its newly identified Cruzeta Target with highly anomalous Lithium values (peak value of 3,712 ppm lithium). This is the highest individual lithium rock-chip result reported since the field program began in November 2024. Readers are cautioned that rock-chip samples are selective by nature and may not represent the true grade or extent of mineralization on the property. The Cruzeta pegmatites are also highly anomalous in tin (peak 372 ppm Sn), niobium (peak 559 ppm Nb), tantalum (peak 87 ppm Ta), gallium (peak 158 ppm Ga), scandium (peak 83ppm Sc), cesium (peak 267 ppm Cs) and beryllium (peak 8 ppm Be). Importantly, samples report potassium/rubidium (K/Rb) ratios as low as 13, indicating high...
