Anson Resources Ltd (ASX:ASN has received further encouraging results from the third and final evaporation technique trial by Outotec on the bulk sample extracted from the Cane Creek 32-1 well.
This work, which is being run in parallel with the lithium extraction process by Lilac Solutions, forms part of Anson’s plan to fast-track the Paradox Lithium Project in Utah, into production.
The goal of the Outotec test work was to study the behaviour of the brine during evaporation and to observe whether the lithium concentration could be increased.

Outotec tested three evaporation processes; heat, vacuum and reactor.
The successful increase in lithium concentration using a reactor to 891 ppm, completed within two hours, resulted in a suitable lithium brine concentration as a feed for the proposed processing plant.
All three evaporation processes tested by Outotec are considered to be successful.
The reactor process was carried out after the extraction of magnesium and calcium, using precipitation, to levels below detection.
The removal of the magnesium and calcium are considered important steps as high concentration of these minerals are considered inhibitors to a successful lithium extraction process.
Anson managing director Bruce Richardson said: “A total of four different processes are being tested for the evaporation and initial processing of the brine to achieve the best economic outcome for the company and add to shareholder value.
“It is very pleasing that similar results have been achieved using the reactor evaporation process on Cane Creek artesian super saturated brines to those achieved using a synthetic brine based upon assay results of brine taken from the Long Canyon.
“While this test work is not complete, the successful removal of calcium and magnesium are important steps.
“The company is continuing with its objective of fast tracking the Paradox Lithium Project into production while at the same time ensuring that the best economic result is achieved for its shareholders.”
