Jindalee Resources Limited (ASX:JRL) has obtained further positive metallurgical test results from the McDermitt Lithium Project in the US with more than 90% of lithium reporting to the leach solution within two hours.
The results from conventional sulphuric acid leaching under a range of temperature, slurry density and time conditions demonstrated results similar to those obtained in previous tests.
Metallurgical testing will continue with the goal of further optimising leach conditions and leachate composition, as well as testing for any beneficiation opportunities.

Drill program to start soon
With relevant approvals and contractors in place, the company’s 2019 drill program is set to begin in the second week of July.
An initial program comprising six core holes has been planned with the aim of locating higher-grade zones, supporting resource estimation work, extending existing mineralised zones at depth and testing for further mineralised zones below the limit of current drilling.
Assays from the program are expected in late August.
Back in April the company also received lithium extraction metallurgy indicating that more than 90% of available lithium reported to the leach solution in four hours.
Jindalee managing director Pip Darvall said at the time: “The testing we’ve been doing has all been about how amenable the material is for the lithium to be leached out of the rock.
“We’ve very pleased with the results … the testing has shown that yes, it is relatively easy to extract lithium and testing is continuing.”
