The sample was taken from the re-opened Cane Creek 32-1 well and the results show both lithium and boron concentrate grades increasing.
Shares surged 83% to 11 cents.
Anson’s managing director Bruce Richardson said: “The unexpected results of the evaporation test work using heat are very encouraging for the success of the Paradox Lithium Project.
“The rapid precipitation of the salts from the brine and the resulting increase in lithium concentration in the brine should provide improved feed for the production plant resulting in improved productivity.”
From 126ppm lithium feed to 900pm after 24 days
Richardson added: “To date the post evaporation feed is expected to be 900ppm. It should be noted that the test work is on-going and a final report from the test work, including the final feed grade of lithium and other minerals, is not expected until mid-August.
“The company will provide updates of the results when they become available.”
Assessing the use of evaporation as a pre-processing step
The objective of the test work was to assess the change in lithium concentration if evaporation was used to precipitate unwanted salts from the brine as a pre-processing step.
Results to date show that the pre-treatment evaporation for a short period would increase the feed grade of the lithium into the proposed extraction process.
The test work is not finalised and evaporation of the brine and the monitoring of the effect on the lithium concentration is continuing.
