Continued drilling by Anson Resources Ltd (ASX:ASN, OTCQB:ANSNF) at the Green River Lithium Project in the Paradox Basin of south-eastern Utah, USA, has confirmed the claustic zones to be geologically similar to those at the Paradox Lithium Project which is 50-kilometres to the south-east.
The company reports that the clastics at Green River consist of the same lithological units but these are deeper and thicker.
This drilling comes after the casing and cementing of the 'intermediate' drilling section to a depth of 7,500ft at the Bosydaba#1 well, which is on the recently purchased private property at the Green River Project.
Drilling began to intersect the salt layers and the clastic zones of the Pennsylvanian Formation at a depth of 6,188ft, with the speed of drilling having increased since drilling through this softer salt and clastic zone commenced.
The 'production' phase is expected to intersect the targeted clastic zone horizons at around 8,800ft.

This drilling program is the first phase in Anson's JORC mineral resource definition plan.
Advantageous structures
The Green River project has many large geological structures — such as the Ten Mile Graben, Little Grand Wash Fault, Green River Anticline and the Salt Wash Anticline — that have resulted in advantageous attributes for the extraction of brines.
These geological structures do not extend to the Paradox Lithium Project area but the lithological units within the clastic zones are similar, providing beneficial factors for extraction.
These include high pressure, increased porosity and increased permeability — factors that strongly indicate low extraction costs and beneficial ESG outcomes.
