Spark Hits 3,712 ppm Lithium at Cruzeta, 118 ppm at Agua Branca; Advances Drill Planning in Brazil's Lithium Valley
- Highest lithium-in-rock result to date of 3,712 ppm at Cruzeta target
- Strong pathfinder elements present including tin (372 ppm), niobium (559 ppm), and tantalum (87 ppm)
- Favorable K/Rb ratios below 150, indicating highly evolved LCT pegmatites
- Advancing toward diamond drilling in Q3 2025
- Results are from early-stage exploration and may not represent true grade or mineralization extent
- Stock options grant of 500,000 shares could lead to minor dilution
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.

"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 highly evolved LCT pegmatites typically associated with lithium fertility.*
*The K/Rb ratio is a well-established geochemical indicator used to identify and prioritize fractionated pegmatites with high lithium potential. Ratios below 150 are considered particularly favourable.

Água Branca Target - Stream Sediment Sampling Results
Stream sediment results from the priority Água Branca target continue to show promise, with a peak sub-basin value of 118 ppm lithium. This result is consistent with previously reported anomalous values and reinforces the broader prospectivity of the area (see NI 43-101 technical report on SEDAR+).
Readers are cautioned that stream sediment survey results are preliminary in nature and are part of an early-stage exploration program. These results are not conclusive evidence of the likelihood of a mineral deposit and do not guarantee future discoveries.

Table 2. Tabulation of lithium and pathfinder element stream sediment analysis results for 46 samples. All samples were submitted to SGS Geosol Laboratories in Belo Horizonte, Brazil, for analysis. Samples were prepared and analyzed using ICP-MS following lithium borate fusion. The typical sample weight was 0.5 to 1.0 kg. SGS is an independent, ISO/IEC 17025-certified laboratory, with no known relationship to Spark Energy Minerals.
