Future Battery Minerals gears up for phase three drilling at Kangaroo Hills Lithium Project, WA

Future Battery Minerals (ASX:FBM) is preparing to start a phase three drilling program this week at its Kangaroo Hills Lithium Project in Western Australia.

The company reports the drilling program will see an initial 4,000m of reverse circulation (RC) completed to infill the Big Red prospect and test the ‘high-priority’ Rocky and Eastern Grey prospects, as well as the Wallaroo and Pademelon regional prospects.

As Future Battery Minerals receives program of work (PoW) and permit approvals, it will expand this phase three program to include between 7,000m and 10,000m of both RC and diamond drilling

Speaking to Mining.com.au, Future Battery Minerals Technical Director Robin Cox says the phase three drilling is an ‘expansive’ next step for the company and is important as it seeks to grow its ‘significant’ discovery.

“We know we’re already onto a highly fertile fractionated LCT pegmatite with some outstanding results. What we’re aiming to find is another thick mineralised pegmatite or spodumene-bearing pegmatite from this drilling, just to continue growing this project.”

Future Battery Minerals reports newly returned assay results further support the significance of the initial March 2023 discovery at Big Red. A series of vertical holes has confirmed the thick ‘high-grade’ mineralisation that remains open to the north and northwest.

Additionally, a resistivity anomaly was identified within Big Red through a recent geophysical review, further indicating a potential strike up to 1km in a north-northwest direction and extending from the current drilling area. The company says this finding further highlights the potential scale of Big Red.

New assays returned from Big Red include hole KHRC031 with 23m @ 1.03% Li2O from 53m; KHRC029 with 15m @ 1.03% Li2O from 39m; and KHRC030 with 13m @ 1.23% Li2O from 41m.

At the Rocky prospect, hole KHRC037 intercepted a spodumene-bearing pegmatite and returned 5m @ 1.12% Li2O from 104m. Hole KHRC028, which was drilled directly east of KHRC037, intercepted a weathered pegmatite from surface with anomalous lithium, tantalum, and tin.

Future Battery Minerals reports these occurrences validate Rocky, which remains open to the south and east and is potentially connected to the nearby Big Red prospect.

Cox tells Mining.com.au the company is ‘really happy’ with the results recorded in phase two drilling.

“When we commenced the phase two drilling, we had a single hole, our discovery hole KHRC011, and that was 29m @ 1.36% Li2O. We really didn’t know much about the area where we had hit that intercept.

We’ve now stepped out around that and found that the pegmatite is continuous, has very good thickness to it, and we’ve seen from our geophysical work that there’s the potential for the Big Red prospect to continue on a strike length of up to 1km.”

The company says assay results for 5 remaining diamond drillholes completed in phase two drilling are still pending. Core samples from these holes will be used in early-stage metallurgical testwork, with results expected in the September 2023 quarter. 

Cox tells this news service that Kangaroo Hills remains a large focus for the company throughout the remainder of 2023.

“We have a lot of ongoing geophysical work that we’re doing, so really happy with the results of resistivity so far, so we’re looking at expanding that survey. Metallurgical mineralogy is very important to us, so we’re expecting the early stage of metallurgical results coming in the coming months, and that’s just going to be an ongoing program for us.

As we diamond drill, we’ll be also looking at the metallurgical liberation and recovery of the spodumene-bearing pegmatite”

As we diamond drill, we’ll be also looking at the metallurgical liberation and recovery of the spodumene-bearing pegmatite. On top of that, we’re currently drilling over at the Nevada Lithium Project. We’ll be looking to wrap that up in July.”

Future Battery Minerals is an Australian explorer focused on ‘key’ battery minerals including lithium, nickel, and copper across its portfolio of assets in Australia and the US.

Kangaroo Hills is a joint venture (JV) between Future Battery Minerals and Lodestar Minerals (ASX:LSR), with the companies holding an 80% and 20% interest, respectively.
