Kingfisher (LON:KGF) Mining Ltd (ASX:KFM) has identified significant additional carbonatites and rare earth element (REE) mineralisation, confirming a substantial REE system at the Mick Well carbonatite complex within WA's highly prospective Gascoyne Province.
Significant new strike lengths of REE mineralisation were discovered from reconnaissance mapping close to the recently identified gravity targets, leading to the discovery of a further 4,100 metres strike of outcropping monazite-dominant REE mineralisation at the Mick Well project.
A substantial REE system has been confirmed with more than 13.5 kilometres of mineralisation mapped so far within a very large 7-kilometre by 4-kilometre carbonatite complex.
The mineralisation is part of a very large intrusion centre of 7 kilometres by 4 kilometres, where carbonatites and mineralisation that have pushed up into the earth’s crust are now exposed at surface.
The newly discovered lodes and carbonatite intrusions increase the cumulative strike length of mineralisation mapped by Kingfisher to more than 13.5 kilometres.
The assays from carbonatites and additional REE mineralisation are expected this month.
Meanwhile, fieldwork continues with REE mineralisation mapping around carbonatite plug targets a high priority.
"A very large and exciting REE system"
Kingfisher executive director and CEO James Farrell said: “The latest discoveries confirm Mick Well is a very large and exciting REE system that extends over an area of more than 7 kilometres by 4 kilometres.
“Our ongoing fieldwork has also identified outcropping ferrocarbonatites together with monazite veining proximal to the recently identified carbonatite plug targets. These are the main ingredients for the world’s largest REE resources.”
The results from the ongoing mapping and rock chip sampling of the high-grade REE system at Mick Well are due later this month, while results from surface geochemistry survey at the large-scale LK1 carbonatite target are expected in December.
