- Exploration at Yarmany in WA has identified a large lithium target at the F-camp prospect
- Main mapped pegmatite is 1km long and 140m wide
- Rock chip sampling has returned up to 1,268ppm Li2O
- Maiden drilling to start next month, targeting lithium and nickel sulphides
Exploration at Yarmany’s F-camp prospect has mapped out a 1km-long pegmatite body with grades of up to 1,268 parts per million (ppm) Li2O, making it the number one priority for a maiden drilling campaign next month.
Yarmany covers 282km2 along the Ida fault – a major regional structure between the Kalgoorlie and Youanmi Terranes which is emerging as world-class lithium province.
This same structure hosts major Goldfields lithium deposits such as Liontown Resources’ (ASX:LTR)156Mt @ 1.4% Li2O Kathleen Valley and Delta Lithium’s (ASX:DLI) 12.7Mt @ 1.2% Li2O Mt Ida.
Four months of exploration culminates in maiden drilling campaign
Exploration since acquiring the project from Horizon Minerals (ASX:HRZ) in July has indicated strong potential for pegmatite-hosted lithium-caesium-tantalum (LCT) mineralisation across a 1km-long and 140m-wide mapped pegmatite called F-camp.
Rock chip sampling from within the F-camp pegmatite target returned up to 1,268ppm Li2O and a bunch of highly elevated pathfinder elements to boot.
These include caesium (Cs), rubidium (Rb), tantalum (Ta) and beryllium (Be), with Cs and Ta elevated, confirming its potential for an LCT pegmatite drill target.
“The initial pegmatite mapping and geochemical sampling activities we have conducted at Yarmany under the expert guidance of Dr David ‘Rowdy’ Rawlings have enabled us to quickly prioritise the best pegmatite targets for drilling,” Metal Hawk MD Will Belbin says.
“The fact that the largest mapped pegmatite in the F-camp target area shows the strongest levels of lithium pathfinder geochemistry is highly encouraging, as these lithium exploration activities conducted so far are from only a very small portion of the Yarmany project.”
Nickel targets identified to date also returned highly anomalous results from rock chip samples of up to 0.64% Ni and 1,402ppm Cu at the Reptile Dam prospect – near the lithium-rich F-camp area.
What’s next at Yarmany?
A maiden drilling campaign is pegged to commence next month and reconnaissance exploration in other parts of the Yarmany project is being planned, as only 10% of the tenement areas has been assessed so far.
Metal Hawk says data from recent historical and regional augur drilling will be utilised to develop regional prospects for further exploration.
While it concentrates on its lithium discovery, nickel sulphide exploration continues and numerous targets from a recent versatile time domain electromagnetic (VTEM) survey will be tested in the upcoming drill program.
“We look forward to drill-testing this exciting prospect as well as a host of nickel sulphide targets in Metal Hawk’s upcoming maiden drilling program at Yarmany,” Belbin says.
“The pegmatite mapping and geochem results at F-camp are ticking all the boxes in the right places. We see great opportunities unfolding at Yarmany and are excited to get the rig out on site next month.”
