Dreadnought Resources intersects high-grade REE at Yin
- Dreadnought Resources intersects shallow, thick and high-grade rare earths at the Yin rare earth element (REE) ironstone in Western Australia
- Drilling is currently underway at Yin, which is part of Dreadnought’s Mangaroon project, with 66 reverse circulation holes being drilled for 5600 metres
- Dreadnought has so far received results for the first six holes, with all striking high-grade REE mineralisation and up to 6.3 per cent total rare earth oxides intersected
- The drilling program is expected to take three months to complete, and the company says it will make regular updates as work progresses
Dreadnought Resources has intersected shallow, thick and high-grade rare earths at its Yin rare earth element (REE) ironstone in Western Australia.
Drilling is currently underway at Yin, which lies within Dreadnought’s Mangaroon project in WA’s Gascoyne region, with 66 reverse circulation (RC) holes being drilled for 5600 metres.
Dreadnought has received results for the first six holes, with all intersecting high-grade REE mineralisation that remains open at depth and along strike.
The samples were analysed in the field by a handheld portable x-ray fluorescence (pXRF) unit and have now been sent off for rush analysis.
Significant pXRF results include 33 metres at 2.5 per cent total rare earth oxides (TREO) from one metre including 10 metres at 6.3 per cent TREO from 11 metres, and 34 metres at 2.9 per cent TREO from 95 metres including 20 metres at 4.2 per cent TREO from 104 metres.
Drilling so far shows two ironstone trends — a 20- to 30-metre-wide high-grade western dyke that dips to the east and an eastern 10-metre-wide dyke.
Dreadnought Managing Director Dean Tuck said the drilling of the rare earth ironstones at Managroon was off to a “fantastic” start, with every hole of the first drill line striking significant thicknesses of mineralised ironstone.
“The intercepts have exceeded expectations and put Yin on the path to be a significant REE discovery,” Mr Tuck said.
“To achieve this result nearly one year to the day of our first rock chips results at Yin is a significant accomplishment and a testament to the hardworking Dreadnought team and our positive working relationships with all stakeholders involved.”
All up, the drilling program is expected to take three months to complete.
Further to the Yin drilling, Dreadnought’s recent airborne magnetic and radiometric survey at Mangaroon identified five ovoid features interpreted as igneous carbonatite intrusions.
Rock chip sampling from the intrusions confirmed REE and phosphate, with up to 2.52 per cent TREO and 15.5 per cent phosphorous pentoxide intersected.
Dreadnought said as the carbonatites remained obscured under calcrete cover, the company would take on RC drilling between June and August to identify areas of mineralisation and improve its understanding of the system.
