Dreadnought Resources confirms high-grade rare earths at Sabre and Y8 targets
Dreadnought has intercepted up to 1m at 7.01% TREO from recent RC drilling across the Sabre and Y8 ironstones at Mangaroon.
Assays received from a first-pass, wide-spaced drilling campaign at Dreadnought Resources’ (ASX: DRE) wholly-owned Mangaroon project in Western Australia have confirmed the discovery of thick, high-grade rare earth elements (REE) mineralisation.
Significant intercepts were returned from 38 reverse circulation holes drilled for a total 4,246 metres at the Sabre and Y8 ironstones, which extend for 15 kilometres of strike and sit within 30km of strike along the Yin complex.
An initial inferred resource of 14.36 million tonnes grading 1.13% total rare earth oxides (TREO) was announced in December at Yin.
It was based on 117 holes for a total 11,907m drilled between June and August and is reported to cover just 10% of the structure.
Drilling results
Best results from Sabre and Y8 were 9m at 1.02% TREO from 7m, including 1m at 7.01% TREO (17% neodymium-praseodymium ) from 12m; 2m at 1.81% TREO from 15m, including 1m at 3.2% TREO (15% NdPr:TREO) from 15m; 4m at 2.01% TREO from 53m including 1m at 6.96% TREO (17% NdPr:TREO) from 53m; and 12m at 1.21% TREO from 51m including 3m at 2.00% TREO (27% NdPr:TREO) from 60m.
Other results were 3m at 2.54% TREO from 14m, including 1m at 4.85% TREO (21% NdPr:TREO) from 15m; 7m at 1.29% TREO from 17m, including 1m at 2.23% TREO (24% NdPr:TREO) from 18m; and 23m at 0.93% TREO from 141m, including 9m at 1.54% TREO (27% NdPr:TREO) from 153m; and 7m at 1.15% TREO from 9m, including 1m at 6.2% TREO (16% NdPr:TREO) from 9m.
Dreadnought said reverse circulation and diamond drilling would restart in February at Yin and at the C1 to C7 carbonatites.
The company expects to release additional resource updates during the year.
Unlocking potential
Dreadnought managing director Dean Tuck said drilling continued to unlock the potential of the Mangaroon project.
“Confirming the Sabre and Y8 discoveries over 8km east of the initial Yin resource underscores the significant potential of the wider ironstone complex to deliver additional mineralisation, discoveries and resources,” he said.
“The success of this first-pass program lays the foundation for follow-up framework drilling and ultimately the delivery of more discoveries along other ironstone trends in addition to Yin.”
