Anson Resources Ltd (ASX:ASN) has received further encouraging results from the extended evaporation test work on a sample from its Paradox Lithium Project in Utah, US.
The sample was taken from the re-opened Cane Creek 32-1 well and the results continue to show both lithium and boron concentrate grades increasing.
Grades are higher than the last update earlier this month, with lithium increasing to 986 ppm on day 28 and boron increasing to 12,400 ppm.

The goal of the test work was to study the behaviour of the brine during evaporation and to observe whether the lithium concentration could be increased.
Lithium concentration needed to be increased to be able to recover it from the brine by a conventional lithium carbonate recovery technique by the addition of sodium carbonate.
The successful increase in concentration to 986 ppm is considered a suitable lithium brine concentration as a feed for the proposed processing plant.

Anson’s managing director Bruce Richardson said: “The significant increase in lithium and other minerals in this work completed by Outotec using a simple evaporation process provides the company with a better understanding of the nature of the brines at the Paradox Lithium Project.
“The precipitation of salts during the evaporation is also a positive and indicates that these high concentrated salts can be easily extracted.
“Both of these significant results assist in the development of the design of production process which is currently underway.”
