Bradda Head Lithium Limited announced results from industry expert Zonge Engineering's magnetotellurics survey (MT), and from Terravision Exploration's GPRplusTM survey (GPRPlus), both carried out at its Eureka asset in Nevada. Highlights: The geophysics results from both programmes demonstrate the potential presence of both brine and clay deposits at Eureka, which is located in Central Nevada, not far from Tesla's Gigafactory and Albemarle's existing Silver Peak Lithium mine, notably the only US lithium mine in operation currently. The MT survey has shown the presence of a potential brine reservoir at varying depths (300m to 2,000m) over a 12km strike length.

Two programmes are now planned for H2 2022: a deeper drilling programme to test the lower basin; a shallow drilling programme to test the clay potential. The surveys also showed geothermal potential at Eureka, which can potentially be used to lower the carbon footprint of lithium production at the asset. Geothermally heated water with anomalous lithium levels is seen at surface near Eureka, which were previously tested in 2016.

Bradda has now staked an additional 16km2 of claims at its Eureka project reflecting the positive results from both geophysical programmes. The GPRPlus survey has also shown the presence of potential clay material, like that seen at Bradda's other sedimentary assets (Basin and Wikieup Projects) down to a depth of c.100m. Previous limited and shallow surface sampling returned grades of up to 550 ppm at Eureka.
