Spark Delivers Shallow Magnet Rare Earths Up To 33% MREO and Gallium from Surface in All Five Maiden Drill Holes
Executive Summary
- Spark Energy Minerals released complete assay data from its first five reverse‑circulation drill holes, showing consistent rare‑earth element (REE) and gallium mineralization across the entire footprint.
- Magnet rare earth oxides (MREO) – the most strategic REE group for permanent magnets – reach up to 33 % of total REOs in several intervals, with TREO grades as high as 6,682 ppm over 2 m.
- Near‑surface gallium mineralization is present in all holes, ranging from 44 – 94 m at 46 – 63 g/t Ga₂O₃, underscoring the project’s multi‑critical‑metal potential.
Key Details
- Drill Program: 5 vertical RC holes (average spacing ≈ 380 m; closest 301 m, widest 423 m).
- Rare Earth Intercepts (selected):
- 78 m @ 2,430 ppm TREO (21 % MREO) – includes 10 m @ 4,522 ppm TREO (25 % MREO) and 2 m @ 6,682 ppm TREO (33 % MREO).
- 34 m @ 2,690 ppm TREO (22 % MREO); 28 m @ 2,031 ppm TREO (21 % MREO); 16 m @ 1,851 ppm TREO (22 % MREO).
- Gallium Intercepts (selected):
- 94 m @ 63 g/t Ga₂O₃ (surface to depth) – Hole ARA‑RC‑001.
- 54 m @ 46.45 g/t Ga₂O₃ – Hole ARA‑RC‑002.
- 58 m @ 52 g/t Ga₂O₃ – Hole ARA‑RC‑003.
- 46 m @ 49.10 g/t Ga₂O₃ – Hole ARA‑RC‑004.
-
44 m @ 47.00 g/t Ga₂O₃ – Hole ARA‑RC‑005.
-
Assay Tables: Full interval data for all five holes (Tables 1‑5) include detailed REE suite, gallium, and ancillary elements (Ce, Dy, Gd, Nb, etc.). Highlights:
- Highest TREO grade recorded: 6,682 ppm (2 m interval).
- Peak MREO percentage: 33 % of TREO.
-
Gallium concentrations consistently > 45 g/t from surface across all holes.
-
Geological Interpretation: Uniform vertical zoning—surface gallium‑rich material transitioning to thick REE‑bearing zones at depth—supports a laterally continuous, supergene‑weathered mineralized system.
