Bradda Head announces results from gravity survey

Bradda Head Lithium Ltd, the North America-focused lithium development group, has announced results from a gravity survey conducted at its Basin clay project in Arizona.

The gravity survey was completed in late 2023 and post-processing has revealed a significant gravity low over the Basin North area, interpreted as a deep, depositional centre for sedimentary rocks and a deep basement rock geological setting.

Summary:

  • Results and location of gravity low have been interpreted to represent thicker clay beds, in both the Upper and Lower Clay sequences – potentially substantially thicker than the previous reported lithium-in-clay intersections from the current 43-101 compliant Resource.
  • Gravity results also led to the reconnaissance on ground 1.6 km to the north but contiguous to the existing Basin licences where new clay and distinct marker bed silica nodules were discovered, indicating the entire clay sequence sits in a shallow setting below post-mineral tuffs and basalt layers.
  • The results of the gravity survey and field reconnaissance prompted the staking of 2.8 km2 of new lode and placer claims to the north on open BLM land, expanding the clay potential significantly.
  • Excellent opportunity to grow the clay deposit to the north and especially to the west where Bradda has over 11 km2 of property to explore, and adds confidence to their intent to reach a new resource of 2.5 million t of Lithium Carbonate Equivalent (LCE) at the end of the upcoming drilling campaign.

Ian Stalker, Executive Chairman, commented:

“The results from this first-ever gravity based geophysical survey in our Basin district in Arizona add to our confidence to reach our new target resource no. of 2.5 million t of LCE with a limited amount of further drilling. This cost-effective campaign is designed to allow us to unlock a further US$3 million payment from LRC, the royalty company that has an existing royalty agreement with us.

“The potential existence of thicker clay beds in both Upper and Lower Clay sequences is hugely encouraging and reaffirms our understanding of our Basin Project as an important resource for lithium-in-clay. The additional discovery of the new clay and silica nodule beds to the north is indicative of favourable opencast based mining conditions, further promoting the value of this project.

“We look forward to commencing our new Basin focussed drilling campaign in the very near future.”
