Lanthanein Resources has identified intrusive carbonatite centres from 3D modelling of airborne magnetic geophysics surveys at its Gascoyne rare earth project in WA.
At least three intrusive targets have been modelled as vertical cylindrical bodies of 2-4km in diameter and extending more than 2km in depth within the company’s Lyons block and along the Bald Hill lineament.
The company says the intrusive carbonatite centres represent a new high-tonnage rare earths target within the area.
Independent consultant and carbonatite expert Franco Pirajno has reviewed the geophysical modelling and will evaluate results from the upcoming maiden drilling program.
Franco has also approved the drill sites which are designed to test the outer magnetic aureoles of the identified targets.
Upcoming drilling will investigate high priority targets within the Gifford Creek carbonatite complex that hosts Hastings Technology Metals’ world-class Yangibana mineral resource of 27.42Mt at 0.97 per cent total rare earth oxides and Dreadnought Resources’ multiple discoveries.
Lanthanein has previously said drilling is critical to understanding the resource potential of the rare earths within the mineralised ironstones.
After coming across high-grade rock chips up to 8.01 per cent TREO and 2.8 per cent combined neodymium-praseodymium, drilling will determine width, grade, strike and depth continuity of outcropping and interpreted ironstone trends.
The company’s wholly owned Lyons block is host to the Hastings and Lanthanein rare earths anomalous ironstone dykes.
Heritage avoidance surveys have been postponed because of positive cases of COVID-19 onsite.
In line with Lanthanein’s health and safety protocols, the survey was temporarily postponed, with all personnel leaving the site but expected to return this month.
Drilling will commence after heritage surveys are complete.
