Spark completed a five-hole reverse circulation (RC) drill program at Arapaima, in Brazil's Lithium Valley.
The maiden five‑hole RC program returned broad intervals of rare earth and gallium mineralization across each collar; see Table 1 in the February 13 NI 43‑101 compliant release for the detailed TREO, MREO and Ga₂O₃ intervals.
Mineralization remains open, and additional drilling is required to determine the full extent, continuity, and economic significance of the system. Assays were completed by SGS Geosol Laboratories with standard QA/QC protocols.
Spark controls a 91,900-hectare contiguous land position in Brazil’s Lithium Valley, providing district-scale exposure within one of the country’s most active hard-rock regions.
The Company’s maiden five-hole drill program confirmed broad, near-surface rare earth and gallium mineralization across multiple holes, demonstrating the scale potential of the system.
With mineralization open in multiple directions, Spark is advancing follow-up drilling to evaluate continuity and expansion potential.
Expanding Beyond Minas Gerais
These assets broaden Spark’s exposure to emerging hard‑rock lithium districts, providing additional drill targets while we continue to test grade and continuity through future campaigns.
Emerging Hard-Rock Lithium District:
The region is gaining recognition for its high-grade spodumene deposits, crucial for producing high-quality Lithium Carbonate Equivalent (LCE)
Lithium Valley Initiative:
In May 2023, the state and municipal governments launched the "Lithium Valley Brazil" initiative, aimed at streamlining lithium development and positioning Minas Gerais as a key global player in the lithium supply chain
With a strong mining legacy and government support, Minas Gerais is emerging as a key hub for lithium and critical minerals development, supported by strong infrastructure and streamlined permitting initiatives.
