- Dreadnought Resources (DRE) lifts its TREO recovery rate to 85.9 per cent through the latest test work on drill samples at its Yin rare earth element ironstone complex
- Independent test work produced a concentrate containing an NdPr:TREO ratio of 35 per cent at an 85.9 per cent TREO recovery
- Two rounds of metallurgical test work have now been completed on Yin ironstones, both producing exceptional TREO concentrates
- Dreadnought aims to optimise its metallurgical work throughout 2023, increasing intensity at all Yin ironstone targets that are expected to yield high resource head grades
- DRE shares closed 1.79 per cent lower at 5.5 cents at market close
Dreadnought Resources (DRE) has lifted its total rare earth oxide (TREO) recovery rate to 85.9 per cent following independent test work carried out on multiple drill samples at Yin, part of DRE’s Mangaroon project in Western Australia.
The latest test work produced a concentrate containing an NdPr:TREO ratio of 35 per cent at an 85.9 per cent TREO recovery.
The company reported that the results represented a 12 times increase from previous head grades of 2.36 per cent TREO and 0.87 per cent neodymium and praseodymium.
Two rounds of metallurgical test work have now been completed on Yin ironstones, both producing exceptional TREO concentrates.
“As the level of metallurgical work becomes more detailed, the ability to produce a high-value concentrate is maintained,” DRE Managing Director Dean Tuck said.
“Our metallurgical studies will continue, as too will the level of engagement with parties interested in potential concentrates.”
Dreadnought also announced interest has been received from Australian and overseas midstream processors for its Yin concentrate.
The company aims to optimise its metallurgical work throughout 2023, increasing intensity at all Yin ironstone targets that are expected to yield high resource head grades.
Additionally, the testing includes acid bake performance analysis by ANSTO of bulk concentrates to optimise midstream processing options for producing a mixed rare earth carbonate.
Dreadnought reported it would continue to utilise flowsheets owned and used by Hastings Technology Metals (HAS) for its advanced Yangibana ironstones project, which has seen extensive testing and development across similar ironstones.
DRE shares closed 1.79 per cent lower at 5.5 cents at market close.
