LITHIUM CARBONATE PURITY RESULTS ARE IN, ENERTOPIA ANNOUNCES 2ND PHASE TESTING

Enertopia Corp. has released the lithium carbonate purity results from Avomeen Analytical Services. The lithium carbonate (Li2Co3) purity rates were from 93.7 per cent to 96.9 per cent from the four samples provided.

"I am very pleased with the purity levels we were able to achieve in the first series of tests and can't wait until the second phase testing starts," stated Robert McAllister, president and chief executive officer of Enertopia.

"The GWT technical team believes that adjustments to the recovery process could result in shorter uptake times and potentially higher lithium recovery rates, and thus potentially higher purity rates of lithium carbonate going forward," stated Nick Nicholas from GWT.

The attached table shows the final lithium recovery rates and purity grade for lithium carbonate.

Note: The lithium recovery numbers reported in
the March 6, 2017, press release were found to
be in error, and the company is retracting the
March 6, 2017, lithium recovery numbers. The
correct total lithium recovery numbers are in
the attached table. The error was picked up in
the final bench test report from GWT; all other
technical data were reported correctly. 

Since late 2016, Enertopia management and consultants have been analyzing industry and peer-reviewed data on lithium brines, soft rock and soils. In conjunction with today's results from the first phase bench tests, the company is looking to determine the optimization of the chemical reagents, number of columns used in filtration and future electro-coagulation reactor size for the next larger bench test that will consist of lithium brines, soft rock and soil bench tests.

Enertopia is confident on its path toward production, processing and recovery of lithium, and upgrading to battery-grade Li2Co3.

Data from four historical samples submitted to GWT for the bench tests were from:

• Sample A, Clayton Valley, United States;
• Sample B, oil well waste water mid-continent U.S.;
• Sample C, Argentine salar;
• Sample D, Bolivian salar.

The purpose of these samples in the bench test is to determine how the technology and proposed recovery process would be impacted by differing chemical compositions and values of lithium in the brines. The focus is to find out what lithium concentration in the brine would be needed for economic recovery in the differing brines per their unique chemical compositions. The next phase of testing will focus on determining the lower concentration of lithium in brine and other lithium sources that will be necessary for economic recovery.

Enertopia's next steps

In the coming weeks, Enertopia will announce the next phase of planning and testing, which will be much larger in scale and scope, and should ultimately lead to the first test pilot plant being built.

"Modern technology is revolutionizing lithium production technology and providing a much better way to recover lithium while minimizing the environmental footprint. We are enthusiastic in becoming leaders in this evolution," stated Mr. McAllister.
