Dreadnought (ASX:DRE) dig in at Yin
September 13, 2023Dreadnought Resources have received assays for 52 holes at Yin and returned the highest grades to date from infill drilling, with heavy levels of neodymium and praseodymium further establishing a globally significant rare earth asset in the West Australian Gascoyne.
A swathe of high-grade intercepts returned high-value NdPr to rare earth ratios over 30 per cent and one hole returned a mighty two-metre stretch of 19.76% TREO.
Dreadnought Managing Director Dean Tuck said the payable results had underscored the global significance of Yin.
“We are also seeing the effectiveness of Dreadnought’s regional geology model; the likely conversion of the large-scale Exploration Target; and the Resource intensity of Yin. The addition of high NdPr:TREO mineralisation north of the current Yin Resource remains highly encouraging as we look to include that material in our next Resource update,” Mr Tuck said.
Mr Tuck added that with resource drilling completed and exploration continuing over other commodities at multi-metal Mangaroon, the company was undertaking a geophysical review of the rare earth ironstones and carbonatites to refine its processes going forward.
Rearing rare earths
The current Inferred Resource at Yin standing at 20.06Mt @ 1.03% TREO covers just four of a 43-kilometre strike length, with the initial 5.52Mt @ 1.23% TREO Indicated resource covering just 250 metres and holding a range of critical minerals.
A resource upgrade is on rails for December, aiming to convert an Exploration Target ranging up to 100Mt at 1.3% TREO from the top 150 metres of the Yin Ironstone Complex.
Dreadnought consider its collection of carbonatites to be the regional source of rare earths and they are already host to a 10.84Mt @ 1.00% resource covering a small area at the C3 carbonatite.
Wide-spaced first pass drilling expanded the total carbonatite area to nine by one kilometres, and Dreadnought expect it will be able to significantly expand the resource there with future drilling.
Multi-commodity opportunities
The nickel-copper-PGE joint venture portion of the project with C$23.77 billion market capper First Quantum Minerals has returned an exciting early result, with the first hole at Bookathanna North along the 45-kilometre-long Money Intrusion intercepting what appeared to be massive nickel-copper sulphides.
A large portion of the completed drilling returned evidence of Ni-Cu-PGE sulphides and successfully confirmed visual, thick, nickel-copper sulphide mineralisation open in all directions over 400 metres of strike.
And an extensive review over a consolidated 5000 square kilometres of fully owned gold rights generated several gold targets, offering high-grade and camp scale gold potential across an untapped 10-kilometre-long shear zone where fractured ownership has limited previous drilling to 200 metres.
