Highlights:
- Consistent rare earth oxide mineralization observed from recent drilling
- Extended intervals of magnet rare earth oxides encountered in the eastern Kary Zone
- Additional drilling and leach test work planned to improve resource classification
The Sybella project, operated by Red Metal (ASX:RDM), is situated in Queensland near the renowned mining center of Mt Isa. This project falls within the rare earth elements sector and is centered on a unique granite body enriched with rare earth oxides. The exploration work has focused on a zone where both weathered and unweathered rock contribute to a continuous system of mineralization that includes key magnet rare earth elements such as neodymium, praseodymium, dysprosium, and terbium.
Drilling Campaign Details
A recent infill drilling campaign in the eastern section of the project area has consistently encountered extended intervals of magnet rare earth oxides. Multiple drill holes have returned substantial widths of mineralized material from near-surface levels. These intersections have reinforced the geological continuity across several traverses within the eastern Kary Zone. The drilling approach has emphasized the collection of data from a series of holes that collectively underscore the uniformity of the mineralized system.
Geological Characteristics
The Sybella site is characterized by a blend of partially weathered and fresh rare earth oxide-enriched granite that stretches over a broad area. The geological setting extends over a considerable distance in length and spans several kilometers in width. Such characteristics underscore the extensive nature of the system and provide a sound framework for ongoing exploration. The rock formations present a continuous body where magnet rare earth oxides are consistently hosted.
Processing Studies
Early metallurgical and comminution investigations have examined a low-cost heap leach processing option suitable for the weathered granite. Laboratory work has achieved the production of a mixed rare earth concentrate that contains nearly half total rare earth oxides, with a substantial fraction attributed to magnet rare earth oxides. The processing tests have focused on maximizing recovery while utilizing methods that require minimal capital expenditure. These studies have laid the groundwork for further examination of direct leaching techniques applied to the weathered material.
Upcoming Field Work
Plans are underway for additional field campaigns that will include drilling larger-diameter diamond core holes to obtain coarse, unpulverised samples. This upcoming work is designed to refine the current resource classification through extended drilling and column leach test work. The forthcoming phase will seek to replicate earlier positive metallurgical results, providing additional confidence in the resource definition. Further on-site testing will also contribute to a more comprehensive understanding of the Sybella project’s geological framework.
