Hammer (ASX:HMX) discover a new LCT field at YandalNovember 22, 2023
Hammer Metals has marked the discovery of a large LCT pegmatite field after hitting the surface extent of a 1.4 kilometre by 600 metre area host to over 100 mapped occurrences at its Yandal Project in Western Australia’s Northeastern Goldfields.
The field is coincident with an anomalous lithium-in-soil response, and sampling has confirmed prospective targets horizons and indicated a zonation bath typical of LCT pegmatites is in operation with increased geochemical levels of lithium.
Hammer Managing Director Daniel Thomas said its recent exploration field work had confirmed the outstanding lithium prospectivity of the Target 1 prospect.
“Detailed mapping has outlined a far more extensive pegmatite swarm than was initially envisaged and soil sampling has confirmed the previously noted bottom-of-hole lithium anomalism,” Mr Thomas said.
“The source of this anomalism is yet to be explained and, with a nearby LCT-type pegmatite field identified at surface, the Company believes that the widespread lithium anomalism may be the halo of a lithium-bearing pegmatite system.
“A targeted Reverse Circulation drilling program is being formulated with drilling likely to commence in early 2024.”
Yandal and Mt Isa copper
The Yandal Project sits in the centre of its namesake belt, a highly prospective stretch home to more than 24 million ounces of gold deposits which has largely been the exploration focus to date.
But its location is also just 40 kilometres from a world-class lithium project at Kathleen Valley, and an extensive soil geochemistry survey early last year returned multiple anomalous responses begging for further investigation, and Hammer now has an extensive field to explore on top of a freshly discovered Tapenade prospect.
And the real prize for Hammer looks to be at Mt Isa, where the explorer holds five copper-gold JORC resources for over 500kt of copper equivalent and a range of prospects with high IOCG potential.
Three of its Mt Isa targets have delivered strikes thicker than 50 metres and exceeding 1 per cent copper, and Hammer is one of the players looking to potentially take the now-vacant throne of Mt Isa production.
