28-Hole Cruzeta Highlights

Results Across the 28
Reported Cruzeta Holes

Across 28 reported RC holes at Cruzeta, drilling has consistently encountered gallium mineralization from surface followed by broad rare earth mineralization below. A review of the complete dataset has also identified scandium, including seven holes with scandium intervals from surface.

Key Observations

Reported Mineralization and Interpreted Footprint

28 holes

Dataset

Cruzeta has progressed from a five-hole maiden program to a reported target-scale dataset.

Sc + Ga

Surface Horizon

Seven holes returned scandium intervals from surface, associated with the iron and titanium oxide fraction that carries gallium.

Ga → REE

Zonation

In reported drilling, near-surface gallium mineralization transitions at depth into a broader rare earth-bearing pattern.

Technical disclosure: grades are in-situ analytical assay results only; no metallurgical recovery is implied. No mineral resource estimate has been established at Arapaima. Reported intervals are downhole widths; true widths are unknown and may differ materially. References to footprint, trend and zonation reflect the Company’s current geological interpretation and do not imply continuous mineralization.

Brazil projects

Arapaima Anchors Spark’s Brazil Portfolio.

Arapaima spans approximately 91,900 hectares and hosts multiple targets for gallium, scandium, rare earth and lithium mineralization. The earlier-stage Solonópole and Currais Novos projects provide additional Brazilian critical-minerals exposure.
