Auroch Minerals confirms LCT pegmatite discovery at Kangaroo Hills Lithium Project, WA

Australian exploration company Auroch Minerals (ASX:AOU) has confirmed a lithium-caesium-tantalum (LCT) pegmatite discovery at the Kangaroo Hills Lithium Project in Western Australia.

The company says assays from 4 drillholes completed as part of phase one reverse circulation (RC) drilling all intercepted spodumene-bearing LCT pegmatites. Assays for the remaining 10 holes completed in phase one are pending.

‘Significant’ results returned include hole KHRC011 with 29m @ 1.36% Li2O from 38m; KHRC001 with 2m @ 1.68% Li2O from 1m; KHRC002 with 7m @ 1% Li2O from 198m; and KHRC004 with 5m @ 0.51% Li2O from 42m.

Auroch reports KHRC011 intercepted a 35m thick pegmatite, which was marked by the geological team for priority analysis. This hole also demonstrated the potential for a large-scale shallow lithium-rich pegmatite.

The company says hole KHRC011 was added late to the drill program after in-field observations led the geology team to believe there was potential for a shallow pegmatite present further east of the planned drillholes. The thickness of the intercept exceeded expectations and at present, Auroch says the mineralised pegmatite remains open to the east, north, and south.

Peak assay within the mineralised zone is 2.91% Li2O at 49m, with grades consistently more than 1% Li2O from 46m to 67m. While drillhole data is limited, the pegmatites are interpreted to be relatively flat lying, which aids predictive targeting. Auroch reports additional RC drilling will be required to determine the scale and depth of this discovery.

Commenting on the results, Auroch Minerals Technical Director Robin Cox says: “Following our first LCT targeted drilling program, the company is extremely pleased to announce the discovery of a shallow high-grade lithium pegmatite. The 29m thick intercept grading at 1.36% lithium oxide (Li2O) is significant for the goldfields area of Western Australia.

The number of mineralised holes also confirms the potential of the Kangaroo Hills Project. Providing further confidence is the confirmed presence of spodumene in the drillholes and surface mineralisation. Significantly, the wide and rich intercept in KHRC011 remains open and the company looks forward to getting back on the ground to commence follow-up drilling.

“The 29m thick intercept grading at 1.36% lithium oxide (Li2O) is significant for the goldfields area of Western Australia”

Also commenting, Auroch Minerals Executive Chairman Mike Edwards says this is a very significant discovery for the company.

“It is a credit to Robin and his technical team that we have managed to go from an initial discovery in November last year to a potentially company-defining discovery in such a short period of time. The capital raise we completed late last year allowed us to hit the ground running in January with drill campaigns at both KHLP (Kangaroo Hills) and in Nevada.

We are fully funded for the planned follow-up program at KHLP and we look forward to updating the market further when more results are received.”

Auroch reports the results of the remaining 10 holes drilling in the phase one program are still pending, and notes the significance of the intercept in KHRC011 warrants immediate follow-up work.

The company says it is currently planning a combined RC and diamond drill (DD) program to step-out and test the extent of the LCT pegmatite. This drilling is expected to begin in the coming 1 to 2 weeks once planning and ground preparation work is complete.

The target generative geophysical review will also run in tandem to the phase two drill program, and Auroch expects that priority targets will be tested following completion of the review.

Auroch Minerals is an ASX-listed exploration company with a portfolio of projects in Australia and abroad. The company currently holds the Nepean, Saints, and Leinster Nickel projects in Western Australia, the Arden Copper-Zinc, Bonaventura Zinc, and Torrens East Zinc and Copper projects in South Australia, as well as the Nevada Lithium Project in the US.
