Enertopia Provides Final Solution Testing Progress Report

Enertopia Provides Final Testing Summary

KELOWNA, BC / ACCESSWIRE / September 24, 2019 / Enertopia Corporation (OTCQB:ENRT)(CSE:TOP) (the "Company" or "Enertopia") is pleased to announce the following lithium project testing update.

The Company has completed the final phase of solution testing, running pre-strip reagent testing to control impurity levels in the Upper Oxide and Reduced drilled horizons from our Clayton Valley, Nevada project.

The goal of these latest tests is to determine how various pH levels with different reagents impact the impurities in each claystone zone. We want to see if pre-stripping the impurities prior to making our synthetic brine is a viable option. This appears to be the case as the potential loss of lithium was below detection limits in all pre-stripping tests.

The latest solution testing was focused on the upper oxide zone, as under any potential mining scenario it would most likely be the first zone mined. The sample size for each test was 20g solids with the ratio being 10% solids in the solution. Due to the success in lowering impurities, we believe we should be able to increase the solids ratio, thus increasing the lithium in the solution going forward using standard off the shelf technology.

Table 1 below showcases the low levels of impurities achieved in one of our completed pre stripping process tests compared to one currently producing Li brine project and one Li brine project currently being evaluated. Reduction of impurities in synthetic brine produced for processing is an essential element of process cost reduction.

Table 1

NOTE: Upper oxide material of 1,158 ppm Li was used as the feedstock. Material was put into solution and agitated for 2hrs at 50c. NA* data not publicly available.

KEY TAKEAWAYS:

• Pre stripping results show high levels of Li being put into solution while maintaining industry-low impurity levels.

• Based on current industry off the shelf technology, we should be able to process a concentration of 40% solids with off the shelf technology bringing our Li concentration in our synthetic brine solution to match the currently producing Li brine project above. This assumes we will be using material from the upper oxide horizon as feedstock and all the while maintaining industry-low impurity levels.

NEXT STEPS:

With the success in impurity removals and after discussions with current industry-leading third parties the next phase of future testing will involve adsorption testing. This process will involve reducing contaminants while concentrating the amount of Li in the final solution.

We continue to believe that the Lithium hosted claystone deposits in Nevada could become major sources of Lithium production in the 2020s and offer the USA a secure domestic supply of battery-grade Lithium products.

Our pre-processing adjustments have demonstrated positive outcomes as contaminant minerals are greatly reduced allowing for a synthetic lithium brine that contains the fewest contaminants to be processed, as compared to any other Lithium project today.

The company's technical advisors believe the positive testing to date may warrant patent protection and thus the Company is keeping all internal data strictly confidential at this time. The Company has signed several NDA's with industry partners as it works to reach its goal of a low capex solution to battery-grade lithium production.

"Our ongoing solution testing of the drilled lithium horizons continues to provide great insights and novel ways to strive for a low-cost mining and processing solution to unlock the potential value of the Lithium enriched claystone." Stated CEO Robert McAllister

Due to the constrained availability for risk capital in the Lithium sector the Company is exploring strategic alternatives which may include without limitation the sale, lease or financing of certain assets of the Company. Additionally, the Company is also looking at a sale or merger or other business combinations such as joint ventures or other strategic alliances in the precious metals sector.

There can be no assurance that this process will result in the successful conclusion of any specific transaction. In accordance with its current and periodic reporting requirements, the Company will disclose further developments with respect to this process pursuant to such obligations.
