The program will drill an area ten times the size of the current JORC resource and will evaluate the potential for a globally significant high-grade NdPr deposit.
Longonjo contains a large new discovery of neodymium praseodymium (NdPr) mineralisation that’s part of the 11.6 million tonnes at 4.30% rare earth oxide (REO) JORC maiden resource.
Scheduled to commence in late August
The two-phase program is scheduled to commence in late August 2018 with first results expected six weeks later.
Drilling will test an area of 2.4 square kilometres which is about ten times the extent of the JORC resource.
Drilling aims to update the JORC resource
The high-grade resource covers an area of 670x350 metres to a depth of less than 30 metres and has mineralisation open in all directions.
The drill program will test the whole of the highly mineralised carbonatite and will enable an updated JORC resource estimate to be reported.
Rift Valley’s chairman Paul Atherley said: “China controls well over of 90% of the world’s production of NdPr which is the core metal used in electric motors for EVs, wind turbines and more generally in the electrification of modern society.
“Currently there is only one listed NdPr producer in the world today (ASX:LYC), which sells most of its production to China.
“Dave Hammond and his team have designed this program with the clear objective of delineating a globally significant NdPr resource at Longonjo.”
