SPARK FAST-TRACKS DRILL PLANNING AS FIELDWORK UNCOVERS LITHIUM-RICH PEGMATITES AT CRUZETA AND CORREGO DO MAQUEM

Spark Energy Minerals Inc. is accelerating exploration at its flagship Arapaima project in Brazil's Lithium Valley, where lithium-rich pegmatites and rapidly evolving drill targets are driving momentum toward the company's inaugural diamond drill program.

Following the June 20, 2025, release of positive lithium assay results from Cruzeta (3,712 parts per million lithium in rock) and Agua Branca (118 parts per million lithium in stream sediments), Spark's geological team has accelerated its on-the-ground efforts across the Cruzeta, Corrego do Maquem and Agua Branca targets. The work is part of the company's broader drill-planning program, with initial diamond drilling expected to begin in Q3 2025.

"Each step we take in the field is strengthening our confidence in these highly prospective targets," commented Spark chief executive officer Eugene Hodgson. "With clear lithium pathfinders and multiple pegmatite bodies already mapped, the refinement of drill collars is progressing exceptionally well. Our team is energized by what we're seeing on the ground and from the air."

Advancing Corrego do Maquem and Cruzeta drill readiness

The Corrego do Maquem target has emerged as a compelling focus for Spark's exploration team. Recent drone reconnaissance and field mapping have revealed several openings from abandoned mining galleries, which are being reinvestigated to assess pegmatite continuity at depth, as well as a structurally controlled corridor with extensive pegmatite outcrops and historical workings.

Meanwhile at Cruzeta, work is under way to characterize the mineralized pegmatite bodies exposed in both historical underground galleries and open-pit faces. These pegmatites are often located just below a shallow weathered cap, making them accessible and highly favourable for drill testing.

Sediment sampling validates broader target footprint

In parallel, sediment sampling efforts are continuing to complement the pegmatite mapping. Stream sediment collection near the Cruzeta corridor confirms persistent lithium pathfinders across key subbasins. These efforts are critical in refining the drill target matrix and to provide data on grade levels of interest, leading to the selection of targets for the drilling campaign.

In one notable site at Cruzeta, an aerial view of a deep vertical gallery illustrates the extent of historical workings, which are now being studied as part of Spark's geological reinterpretation and 3-D modelling for coming drilling.

"Drilling is the ultimate validation tool in exploration," added Mr. Hodgson. "But what we're building now is the framework for success: boots-on-the-ground geology, multilayered sampling and a meticulous, science-first approach."

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.

Looking ahead

Spark remains on track to initiate its first phase of diamond drilling in Q3 2025, with a primary focus on the Cruzeta, Corrego do Maquem and Agua Branca targets. This drill program represents the next major milestone in unlocking the lithium and rare earth potential of the company's expansive 91,900-hectare land package.
