  • Mississippian Units estimated to be 650ft to 660ft thick
  • Assay results and data sent to third party for JORC resource upgrade
Full Summary

Anson Resources Ltd (ASX: ASN) is pleased to announce that it has received a lithium assay of 148ppm from the drilling fluid that circulated the Mississippian horizon at 9,189ft in the re-entry drilling program of the Mt Fuel-Skyline Geyser 1-25 well. The aim of the program was to confirm lithium-rich brines in the target horizons, which will be used to increase the overall Project JORC Mineral Resource. The drilling program was not able to continue beyond 9,239ft due to technical difficulties, preventing the collection of brine samples from the Paradox Formation, Clastic 31. However, the drilling fluids recovered from the Mississippian Unit were sufficient to allow for assays to be conducted, which determined a lithium grade of 148ppm, higher than that recorded at the Boysdaba #1 well. Anson's 3D models have estimated the interpreted thickness of the Mississippian Units at the Mt Fuel-Skyline Geyser 1-25 well to be 650 to 660ft. All data from the Mt Fuel-Skyline well, including fluid assays results and 3D modelling thickness estimates, have been sent to an independent company for consideration in the revised JORC resource estimate review, which has already commenced.

Outlook

Anson is focused on developing its Green River and Paradox Lithium Project in Utah into a significant lithium producing operation. The company is working on increasing the JORC Resource estimate through various efforts, including engineering studies, government approvals, and financing options for a full-scale production plant.
