Lightning Minerals enlists contractor for inaugural drilling at Dundas Project, WA

Critical minerals explorer Lightning Minerals (ASX:L1M) has enlisted drilling contractor Gyro Drilling Australia to undertake an inaugural program at the Dundas Project in Western Australia.

The company reports Gyro will undertake 2,500m of reverse circulation (RC) and 10,000m of aircore (AC) drilling in the week starting on 5 June 2023 across tenement E63/2001.

This drilling program will follow up on a combination of recent priority targets identified by the mapping of outcropping pegmatites, geophysical reinterpretations, and lithium-rubidium-in-soil anomalism identified in the southeastern corner of the tenement.

Lightning expects the RC component to be undertaken first to test the continuation of the 3 outcropping pegmatites at depth. If the outcrop is proven to continue, the company intends for the program to collect samples from depths between 50m and 100m vertically from surface.

The company says this will provide a more representative sample from beneath the interpreted base of complete oxidation. However, the continuation or orientation of the pegmatites is not yet known, and as such, Lightning says there are no guarantees of success in the maiden drilling program.

Once the RC component of the drill campaign is complete, Lightning reports it will then start the AC program in the southeastern corner of E63/2001. This program will target lithium and rubidium anomalism previously reported by the company, as well as potential extensions of pegmatites present in the south of the tenement.

The company says composite samples will be taken through areas of saprolitic cover to help vector towards any pegmatites that are not intersected within the maiden AC program.

If pegmatites are intersected, Lightning reports a follow-up RC program will be considered a priority to accelerate exploration within the tenement. Adjustments to final collar locations are also expected as the drill plan develops and evolves in the field.

Commenting on the upcoming maiden drilling campaign, Lightning Minerals Chief Executive Officer (CEO) Alex Biggs says: “It is with pleasure and excitement that we announce our inaugural drill campaign at Dundas.

The past few months have been crucial in establishing target areas for drilling, and I commend our team on a job well done in demonstrating multiple targets and opportunities as we accelerate our exploration.

Drilling on E63/2001 is just the start, with numerous other lithium targets to follow up across our Dundas tenements”

Drilling on E63/2001 is just the start, with numerous other lithium targets to follow up across our Dundas tenements. We welcome our contractors to site and look forward to working together as we begin the journey of unlocking the potential that Dundas holds. Once again, I thank our shareholders and stakeholders for their support in Lightning Minerals and our team.”

Lightning also reports additional infill sampling campaigns will now be reviewed at the Dundas North Project following ‘positive’ discoveries in the area, including lithium-in-soil anomalism up to 147 parts per million (ppm) lithium and 3 ‘large’ lithium target areas, the largest of which covers 35km-square.

The company says a ‘comprehensive’ targeting exercise using the results of the reconnaissance sampling will now be undertaken to extract maximum value from the 62-element suite of analytes provided by the ultrafine (UFF+) analytical technique.

This review will include all applicable prospective commodities for the project, including lithium, rare earth elements (REE), gold, copper, nickel, and platinum group elements (PGE).

Lightning Minerals is an ASX-listed critical minerals explorer focused on its tenements across Western Australia. Along with Dundas, the company also holds the Mt Jewell, Mt Bartle, and Mailman Hill prospects, which are considered prospective for base and critical minerals.

The flagship Dundas Project lies within the Dundas region of Western Australia and covers 8 tenements between 2 project areas that encompass 454km-square of land near Norseman.
