Kairos Minerals (ASX:KAI) has its sights set on cost-effective resource estimation drilling at its Roe Hills North Rare Earth Element (REE) and Lithium Project in Western Australia.
The proposed drilling follows the completion of a 2,368-station ground gravity survey.
The gravity survey was designed to test the extent of buried REE-bearing syenite intrusions responsible for clay-hosted REE mineralisation recently uncovered by drilling at the Black Cat deposit.
Atlas Geophysics completed the survey and gathered gravity readings from Black Cat, as well as the Crystal Palace and Blue Jay prospects.
Results from the survey map-out a coherent 2.2km-by-1.2km gravity low at Black Cat, which is supported by limited previous drilling at Roe Hills.
According to Kairos, the prior drilling provides evidence that the gravity lows are syenites.
With this in mind, Kairos believes gravity lows are believed to be a proxy for buried syenites and rare earths. To date, only 10% of the potential syenite area has been tested at Black Cat and Blue Jay.
Preliminary metallurgical testwork of drilling composites is now underway to test characterisation and beneficiation of clay-hosted REE mineralisation.
Managing Director Peter Turner says all indications from previous drilling lead the company to believe it has a high-grade clay-hosted REE project on its hands.
“We will now undertake low-cost aircore drilling to test for rare earths in these areas,” he says.
Meanwhile, the company will continue field mapping and sampling on the southern part of Roe Hills, while simultaneously completing auger soil sampling to extend southwards on the tenement package.
Kairos Minerals is an ASX-listed exploration company targeting lithium and gold discoveries in Western Australia.
The Roe Hills project is wholly owned by Kairos and is located 120km east of Kalgoorlie in Western Australia’s Eastern Goldfields.
The project comprises an extensive tenement portfolio where Kairos’ exploration work has confirmed the potential for discoveries of gold, nickel, and cobalt mineralisation.
