 Anson Upgrades Green River JORC Resource Estimate by 650%
Key Points
  • Green River Lithium Project JORC Resource estimate increased by 650%
  • Indicated Resource - 183,000 t of lithium carbonate (863% increase)
  • Inferred Resource - 590,000 t of lithium carbonate (602% increase)
Full Summary

Anson Resources Limited (ASX: ASN) through its 100% owned subsidiary Blackstone Minerals NV LLC has completed an upgrade to the maiden JORC Mineral Resource interpretation by 650% on the Mississippian Leadville Limestone at its Green River Lithium Project in south-eastern Utah, USA. The Indicated Resource was upgraded to 183,00 metric tonnes of lithium carbonate equivalent (LCE) an increase of 863%, and the Inferred Resource by 602% to 590,000 metric tonnes of LCE. The resource estimate is expected to further increase from the granting of additional claims that are already under application. The JORC Resource estimate upgrade was conducted by a third-party geological consulting company based in North America which took into consideration the recovery of the drilling fluids in the Mississippian Units when the drilling program at the Mt Fuel-Skyline well was suspended. The brine that had entered the heavy drilling fluids during the drilling of the Boysdaba#1 Well proved to be similar to that of raw brine later collected, and it was considered that a similar result would be achieved if a brine sample could have been collected from the drilling program at the Mt Fuel Skyline Geyser 1-25 well. The Company is lodging applications for the mineral rights within the expanded Area of Interest (AOI), and if successful it is expected that the JORC Resource estimate will be further increased.

Guidance

The Company's objective is to achieve an Indicated and Inferred JORC Resource estimate of over 1 million tons of LCE at Green River.

Outlook

The Company expects to achieve its JORC Resource goal of over 1 million tons of LCE without further exploration drilling if the additional mineral rights within the new Area of Interest are granted.
