Pure Energy Begins Next Phase of Process Test Work with BAT for Clayton Valley South CVS Lithium Project

Pure Energy Minerals Limited (the "Company" or "Pure Energy") is pleased to announce that it is rapidly advancing its Clayton Valley South ("CVS") lithium project by beginning the next phase of process test work with Bateman Advanced Technologies ("BAT" or "Bateman"), a Tenova Group Company. As part of its ongoing work towards a Preliminary Economic Assessment expected in 2016, the Company has secured access to BAT's state-of-the-art Research and Development Center in Katzrin, Israel.

During early 2016, the Pure Energy - Bateman team will commence trial processing runs in BAT's Mini Pilot Plant designed to recover high-purity, battery-grade lithium products from brine sourced from Pure Energy's CVS Project, located near Silver Peak, Nevada.

BAT has developed a novel proprietary technology for the efficient and effective recovery of lithium from brines and chemical waste streams using a proven process with a small environmental footprint. In 2014, Pure Energy engaged BAT to conduct bench-scale testing of the LiP™ and LiSX™ processes (see below) on brine from the Company's CVS Project. The bench-scale testing succeeded in producing a Lithium Chloride solution with a purity greater than 99.9%. The Li concentration in the waste stream was below the detection limit -- indicating practically 100% Li recovery (see news release dated April 20, 2015).

The proposed lithium recovery process that will be tested in the Mini Pilot Plant consists of three distinct phases:

LiP™ - Removal of alkali earth elements using membranes

LiSX™ - Recovery of lithium into concentrated high-purity lithium sulfate solution utilizing proven solvent extraction process

LiEL™ - conversion of the lithium sulfate solution into a concentrated high-purity lithium hydroxide solution, using electrolysis, and subsequent crystallization into high-purity battery grade lithium hydroxide

At the end of the Mini Pilot test work, TBT will complete a report including:

  • Description of analytical methods and laboratory procedures
  • Description of the mini-pilot tests and operating conditions
  • Results of the mini-pilot tests with analytical data on efficacy and efficiency of lithium recovery
  • Recommendations for the continuous pilot stage and additional engineering studies
  • Initial recommendations for industrial scale, including preliminary flowsheets
  • Scale-up data, including preliminary estimates of capital and operating costs at industrial scale

Pure Energy CEO Robert Mintak commented, "We are 15 years into the 21st century and the current producers of lithium materials for the green economy still rely on inefficient, environmentally challenging, capital intensive 20th century processes. Significant advancements have taken place in mineral processing and battery material production technologies, and the suite of BAT processes is designed for high rates of lithium recovery, a smaller environmental footprint and lower investment cost. Securing access to this facility at the correct stage in the development timeline for Pure Energy is a huge advantage, and will provide crucial information relating to the cost and efficiency of using these new processing techniques to produce battery-grade materials from the CVS Project. Pure Energy is focused on developing the most efficient lithium recovery technologies for the CVS Project, and is engaged in ongoing work with other world-class technology leaders in the sector."
