SGS Laboratory in Belo Horizonte, Brazil, has released Spark's analytical results for 107 samples (63 rock chips, 35 stream sediments and 9 soil samples) from Spark's initial generative greenfield exploration undertaken across its extensive 64,359-hectare contiguous tenement package in Q4 2024. Rock chip and mineral separate samples were collected from highly weathered and oxidized pegmatitic material at surface, while stream sediment samples were collected from trap sites believed to contain representative material derived from distinct drainage basins prospective for lithium. All samples are sent for low detection multi-element ICP geochemical analysis.
Summary of Spark's analysis of the assay results:
- Anomalous analytical results for lithium and closely associated pathfinder elements in rock chips (up to 582ppm Li) confirm that a 21.5km strike of pegmatite trends delineated in Q4 2024 are lithium-bearing and prospective for potentially economic lithium mineralization at depth below the level of surface depletion.
- Targets 1 and 5 continue to remain top priority as the sample results clearly define lithium anomalism along the main pegmatite trends mapped. These two targets will now attract detailed, focused follow-up mapping and sample programs (trenching, pitting, systematic channel sampling of old mining excavations and potentially geophysics) with the aim of generating an initial drilling phase during Q2 2025.
- Positive stream sediment results for lithium (up to 191pm Li) and associated pathfinder elements Niobium (up to 35ppm Nb), Barium (peak Ba 460ppm), Cesium (up to 31ppm Cs), Magnesium (up to 3,925ppm Mg), Rubidium (up to 437ppm Rb), Tin (up to 17ppm Sn), Titanium (up to 2,492ppm Ti) and Zirconium (up to 169ppm Zr) have highlighted six (6) drainage sub-basins anomalous in lithium for follow-up exploration from results reported to date.
- The stream sediment results also confirm the highest probability drainage basins for lithium as defined by the 2016 and 2024 government reports and fully justify the company's strategy to initially focus exploration in these areas within the extensive greenfield tenements package supported by Spark's geological interpretation.
- Reconnaissance orientation soil samples from various geological domains across the portfolio reported anomalous lithium (up to 55 ppm Li) and pathfinder elements including Rare Earth Elements (up to 503 total rare earth oxides – TREO), Bismuth (up to 6.3ppm Bi) and Tin (up to 20ppm Sn) and associated enrichment in Gallium (up to 49ppm Ga) and Niobium (up to 46ppm Nb).
- The positive results presented across various sampling mediums (rock chips, stream sediments, and soils) confirm the viability of low detection multi-element geochemistry for exploring the highly weathered-oxidized tropical regolith profiles developed over Spark's extensive tenement package. The team will continue to evaluate and refine.
- The results presented here have been provided to Sahara Mining Services for independent evaluation as part of their preparation of an NI 43-101 Exploration Report following their site visit in January. The final report is anticipated to be completed by the end of February.
- Exploration continues across the portfolio with over a combined 31km strike of pegmatite trends defined to date associated with ~90 individual pegmatite bodies identified within 11 pegmatite trends. To date over 50 historical artisanal mining areas have been identified within Spark's tenements.
- Additional samples provisionally identified as weathered spodumene were collected from these old artisanal workings and will be submitted for XRD analysis this week in Belo Horizonte (Previously submitted samples are still awaiting results).

Lithium concentrations in tropical weathered systems:
There are many examples from the nearby Lithium Valley and elsewhere globally whereby relatively low tenure lithium sampling results from samples collected from oxidized and leached surface pegmatite samples (lower tenure but still above detection, and highly anomalous relative to background crustal abundances) have been found to reflect significantly higher grade, potentially economic, lithium mineralization hosted by these pegmatites at depth.
In addition to low tenure but anomalous lithium values, there are several other geochemical characteristics in the initial data to highlight. These include Potassium / Rubidium (K/Rb) ratios reflecting melt fractionation at levels consistent with the evolved melts required for lithium pegmatite formation, very high correlation between lithium and niobium, highly anomalous Tin, Tantalum, Gallium, and Niobium, a low Tantalum / Niobium ratio which is important in identifying spodumene rich pegmatites, soil samples are enriched in Gallium, Niobium, Bismuth and Tin.

Arapaima Lithium Project Highlights:
- Spark Energy's 64,359-hectare land package runs parallel to Sigma Lithium, Brazil's largest lithium company with a market cap of ~C
$2 billion and sits only 15km away at the closest point.
65% of the extensive tenement package remains to be explored, underscoring the potential as new pegmatite corridors continue to be uncovered.
- The total combined pegmatite trend inventory contains 11 pegmatite trends with 90 individual pegmatites mapped over a combined strike length of 31km.
- To date, 54 historical artisanal mining excavations have been identified and mapped by Spark's geological team. These areas are all focused on pegmatite occurrences with evidence for prior exploitation of gemstones (topaz, aquamarine – beryl), feldspar, quartz and tourmaline.
- Moving into February, the exploration program and strategy will include a detailed follow-up of anomalous analytical results in the priority areas as well as continued investigation of the remainder of the Arapaima Lithium Project.
QA/QC Protocols
Spark maintained full chain-of-custody control from sampling through to laboratory delivery, ensuring the reliability of the assay results. SGS Laboratory used QAQC protocols for blanks, standards and duplicates, the results of which are reported alongside the completed analysis.
