OD6 Metals uncovers ‘outstanding high-grade’ clay REEs at Splinter Rock Project, Western Australia

OD6 Metals (ASX:OD6) reports it has uncovered ‘outstanding high-grade’ clay rare earths (REEs) mineralisation at the Splinter Rock Project, located northeast of Esperance, Western Australia.

The company says 4 prospects including Scrum, Centre, Flanker and Prop targeted in a recent drilling program all included drillholes that intersected grades and intervals greater than 20,000ppm TREO representing ‘significant’ accumulations of mineralised clay-hosted REE deposits. It also notes all zones are open orthogonal to drill lines and are anticipated to extend laterally over several kilometres.

The drilling program consisted of 179 holes and assays have been received for 65 holes, with 32 of the holes returning ‘significant’ TREO grades and thickness using a 750ppm cut-off grade with clay thickness intervals up to 33m. OD6 says MREOs make up an average of 22.5% with CREOs averaging 24.2% plus HREOs averaging 10.7%.

OD6 reports 47 of the 65 holes have also returned ‘significant’ TREO grade and thickness using a 300ppm cut-off grade with thickness intervals ranging up to 80m, with MREOs making up an average of 2.2%, CREOs averaging 24.2% and HREOs averaging 11.2%.

The company’s share price rocketed 45.652% as of 9.30am AWST.

OD6 Managing Director Brett Hazelden said these initial REE assay results are outstanding and represent some of the highest grades and thickest clay-hosted REE intersections seen in Australia.

“The extent and consistency of these shallow, high-grade clays have resulted in 4 significant prospects being identified”

“The extent and consistency of these shallow, high-grade clays have resulted in 4 significant prospects being identified that are between 4km and 7km in width which are open at length on our 2,579km-square Splinter Rock project.

Importantly, these drill results validate historic assays, plus they extend the discovery of clay-hosted REEs across a new drill line perpendicular to the original line. This bodes well for future drilling, which we anticipate will significantly grow the known mineralised area.

The project with its proximity to port and renewable energy generation potential, now has the very real potential to be a globally significant, world class group of mineral systems that could be a multigenerational asset as the world transitions to the decarbonised economy.

The scale of these clays is hard to comprehend when you start talking multiple kilometres in one direction at a thickness of between 10m to 30m. The potential is massive.”

Significant intercepts recorded by OD6 include 41m @ 1,262ppm from 15m including 29m @ 1,585ppm TREO from 27m in SRAC0151, 30m @ 1,576ppm TREO from 15m including 27m @ 1,716ppm TREO from 18m in SRAC0033, and 21m @ 2,029ppm TREO from 18m including 18m @ 2,249ppm TREO from 21m in SRAC0042.

Other ‘high-grade’ intercepts include 27m @ 1,400ppm TREO from 18m including 3m @ 1,619ppm TREO at 18m, 6m @ 4,139ppm TREO from 27m and 2m @ 1,668ppm TREO from 75m in SRAC0149, as well as 46m @ 800ppm from 6m including 7m @ 2,227m from 45m in SRAC0028, and 20m @ 1,623ppm TREO from 15m including 14m @ 2,059ppm TREO from 21m.

Scrum

According to the company, the Scrum Prospect extends for around 6km along a northwest-southeast drill line and is yet to be constrained with REEs located in thick areas of the prospect varying between 12m to 33m with TREO values up to 1,563ppm at a 300ppm cut-off grade.

The Centre Prospect extends for around 5km along a northwest-southeast drill line and is yet to be constrained, and REEs are located in thick areas of the prospect varying between 10m to 30m with TREO values up to 2,287ppm at a 300ppm cut-off grade.

OD6 reports the Flanker Prospect extends for around 4km along a northwest-southeast drill line and is also yet to be constrained, with REEs located in thick areas varying between 20m to 30m with TREO values up to 1,623ppm at a 300ppm cut-off.

Lastly, it says the Prop prospect extends 5km to the northwest-southeast and 7km to the northeast-southwest on drill lines, and REEs are located in thick areas varying between 10m to 80m with TREO values up to 1,400ppm at a 300ppm cut-off.

The Splinter Rock Project is a 2,579km-square tenement package located around 150km northeast of Esperance in Western Australia. OD6 reports the REE mineralisation is currently inferred to be a mobilised weathering product of the REE enriched Booanya granite suite, and the target area of the project covers over 40km by 60km, or around the same size as the Australian Capital Territory.

OD6 Metals is an Australian exploration and development company operating in the Goldfields-Esperance region of Western Australia, and its projects include the Splinter Rock Project and the Grass Patch Project.
