Twenty Seven Co Ltd (ASX:TSC) has revealed the highly prospective, multi-element nature of its Trident Project near Broken Hill in New South Wales through an extensive surface rock chip sampling program.
The northern portion of the project was sampled with 152 rock chips from within areas historically reported to be high in anomalous copper, gold, tin and other critical elements.
Best results included up to 17.60% copper, 1.275 g/t gold and 2.44% tin in addition to rare earth elements niobium, tantalum and rubidium grading up to 1080ppm, 676ppm and 3080ppm respectively. The positive gold and copper assays confirm the potential for an iron oxide copper-gold mineral system.
Numerous high-grade copper and gold areas will be sampled in the next program as a matter of priority, while selective samples of the rare earth element pegmatites will be tested to better identify their makeup.
“Significantly underexplored”
“We are pleased with these early results from our sampling at Trident which confirm the highly prospective multi element nature of the project,” Twenty Seven Co CEO Simon Phillips said.
“We are very encouraged by the strong copper, gold and tin mineralisation identified. The Trident Project remains significantly underexplored and we believe we are only scratching the surface in terms of the mineralised potential of this region.
“We look forward to the TSC geological team following up these results with further work early in the new calendar year.”
Initial exploration of the rare earth element pegmatites indicate they likely do not contain lithium group elements (lithium-caesium-tantalum) but rather appear to host NYF mineralisation (niobium-yttrium-fluorine).
Due to the nature of rare earth pegmatites, various other rare earth elements at a range of concentrations were found within the mineralisation, including scandium, zirconium, uranium and thorium.
Due to the crystallisation of the pegmatites, they also contain yttrium, carbon, beryllium, gallium, niobium, tantalum and fluorine in producible levels.
Next steps
Twenty Seven Co is an Australian explorer focused on creating shareholder value through discovering mineral resources.
TSC's intended next steps over the coming months include:
- Plan further infill geochemical sampling around the high-grade copper, gold and tin rock sample results;
- Submit selective samples for REE analysis;
- Visit the Perseus tenement once mustering allows access;
- Commence drilling key anomalies at the Rover Project in WA;
- Receive assay results from Rover; and
- Drilling scheduled for NSW Midas project February 2022.
