KELOWNA, British Columbia, March 01, 2018 (GLOBE NEWSWIRE) — via NetworkWire – Enertopia Corporation (OTCQB:ENRT) (CSE:TOP) (the “Company” or “Enertopia”) is pleased to announce the following updates for the recovery of Lithium and ultimately, upgrading the Lithium to battery grade Li2CO3 by our technology partner Genesis Water Technologies Inc., (GWT) a leader in specialized water treatment solutions.
BENCH TEST UPDATE:
GWT has informed the Company that the bench scale build will be completed during the week of March 4th 11th. Pre-testing with synthetic Li brine solutions will commence the following week. Synthetic Li brine solution testing will continue throughout the remainder of March and April. Final 3rd party lab results are currently expected by the end of May.
Enertopia is excited about supplying GWT with synthetic Li brine samples made from Li enriched surface samples from the Company’s Clayton Valley project. After months of testing by 3rd party labs and internal analysis by GWT and Enertopia consultants, it has been determined that the synthetic Li solutions will be composed of surface host rock samples from the bulk samples GWT-001 and GWT-002.
Synthetic Li brine solutions having a pH of 2.0 will be achieved using H2SO4 and synthetic Li brine solutions having a pH of 11.0 will be achieved using NaOH or Ca(OH)2.
Solution testing will take place at various temperatures from 20o C to 80o C.
The goals of these series of bench tests are to test, in a precise manner, the effect of higher solution temperature and varying pH and the response of the patent-pending GWT ENERLET Lithium recovery process.
Our 3rd party testing has revealed that by using a high pH of 11.0 or a low pH of 2.0 allows for 47.75% in the case of pH 11.0 to 50.56% in the case of pH 2.0 of the lithium in solution to be recovered. However, using solution with a pH of 11.0 results in a significant drop in the levels of contaminant minerals that need to be removed in order to obtain battery grade Li2CO3 as per the table below. Especially note the reduction in both Mg and Ca in synthetic brine produced using an alkaline leach.
|Bulk Sample #
|Li in mg/l||Mg in mg/l||B in mg/l||Ca in mg/l||K in mg/l|
|pH 2.0 using H2SO4||180||228||47||907||213|
|pH 11.0 using NaOH||160||0.006||57||33.1||241|
|pH 11.0 using Ca(OH)2||160||0.019||45||296||265|
NOTE: 1 ppm = 1 mg/l
Above pH 2.0 solution comprised of 2,000ml water, 500g Li sample rock
Above pH 11.0 solutions comprised of 800ml water 200g Li sample rock
The potential quantity and grade is conceptual in nature, and there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resource.
The Company looks forward to the synthetic lithium brine solution testing through the GWT ENERLET Lithium recovery system over the next two months. While these tests are ongoing, GWT and Enertopia are mapping out the next steps reviewing the planned pilot plant and ways to potentially lower the capex and electrical consumption based on the positive data received thus far with the just completed 3rd party lab analysis.
The Company will be at booth 3347 at the Prospectors and Developers Association of Canada (PDAC) this year from March 4-7 in Toronto, ON. Modern technology is changing the face of mining.
“Enertopia looks forward to providing updates as to the results of the bench test analysis and our ongoing project work at our 100% owned Clayton Valley, NV, Lithium project, as well as continuing due diligence in the technology and mineral sectors. Modern technology is revolutionizing ways to mine and protect our environment. We are enthusiastic about becoming leaders in this evolution,” Stated President and CEO Robert McAllister
“Genesis Water Technologies looks forward to the continued optimization of the leach process of the synthetic brine sample and our GWT Enerlet Lithium recovery process. We are enthusiastic to be on the cutting edge of advancements in lithium extraction to provide battery grade lithium to industry,” Stated Technical Manager Nick Nicholas.
Third party laboratory testing was carried out by BASE Metallurgical Laboratories Ltd. and independent rock and synthetic brine assays were carried out by ALS Geochemistry of Vancouver, BC. Head grade rock analysis was completed using ME-ICP61, with synthetic brine analysis completed by using ME-MS14b, ME-ICP14, ME-ICP15, and tail analysis was completed using ME-ICP61.
