Press Release #201710                FOR IMMEDIATE RELEASE   April 20, 2017           

Lithium Carbonate Purity Results Are In, Enertopia Announces 2nd Phase Testing

Vancouver, BC-Enertopia Corporation (ENRT) on the OTCQB and (TOP) on the CSE (the "Company" or "Enertopia") is pleased
---> to announce the lithium carbonate purity results from Avomeen Analytical Services. The lithium carbonate (Li2Co3) pur
--->ity rates were from 93.7% to 96.9% 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 th
--->e second phase testing starts." Stated Robert McAllister, President and CEO of Enertopia.

"The GWT technical team believes that adjustments to the recovery process could result in shorter uptake times and pot
--->entially higher lithium recovery rates and thus potentially higher purity rates of Lithium Carbonate going forward." s
--->tated Nick Nicholas, from GWT.

The Table below 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 com
--->pany is retracting the March 6, 2017 Lithium recovery numbers. The correct total lithium recovery numbers are in the t
--->able above. The error was picked up in the final bench test report from GWT, all other technical data was reported cor
--->rectly. 

Since late 2016 Enertopia management and consultants have been analyzing industry and peer review data on lithium brin
--->es, soft rock and soils. In conjunction with today's results from the first phase bench tests we are looking to determ
--->ine the optimization of the chemical reagents, number of columns used in filtration, future electro-coagulation reacto
--->r 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 towards production, processing and recovery of Lithium and upgrading to battery gra
--->de Li2Co3.  

Data from four historic samples submitted to GWT for the bench tests were  A Clayton Valley, USA
Sample B, Oil well waste water mid-continent USA
Sample C, Argentina, Salar
Sample D, Bolivia 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 Lith
--->ium 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 oth
--->er Lithium sources that will be necessary for economic recovery.

ENERTOPIA 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 Pres
--->ident and CEO Robert McAllister
