Bradda Head Lithium reports survey results from Eureka asset
Published by Will Owen,
Global Mining Review,
Bradda Head Lithium Ltd has announced the results from Zonge Engineering’s magnetotellurics survey (MT) and from Terravision Exploration’s GPRplusTM survey, both carried out at its Eureka asset in Nevada, US.
- 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 (300 m to 2000 m) over a 12 km strike length.
- Two programmes are now planned for 2H22:
- 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 can be found at the surface near Eureka, which were previously tested in 2016.
- Bradda has now staked an additional 16 km2 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 approximately 100 m. Previous limited and shallow surface sampling returned grades of up to 550 ppm at Eureka.
Charles FitzRoy, CEO of Bradda Head, commented:
“These results support the potential of Eureka that our geological team have always believed to be the case. This will enable us to go ahead with plans for a drilling programme to test the observed brine reservoir and a shallow drill programme to test the clay to maximise the resource’s full potential whilst further exploring Eureka’s lower basin.
“Furthermore, Eureka has additional benefits in that it has demonstrated considerable geothermal potential. This is a key point as it could enable us to lower our carbon footprint and running costs for lithium extraction from Eureka – mirroring Bradda’s vision and strategy.
“2022 has already been strong for Bradda, with the exercising of the Cheto option covering portions of Basin East and West [and] the positive metallurgical testwork results from Basin East [–] demonstrating the potential to extract 99% of lithium from leach whilst the company remains very well-funded via its Royalty agreement with LRC. The additional news at Eureka is a further sign of Bradda’s fast-track approach to developing its assets, and we expect to announce more newsflow for Eureka over the course of 2022.”
