Enertopia Provides Claystone Fraction Testing Progress Update 4

Kelowna, BC—Enertopia Corporation (ENRT) on the OTCQB and (TOP) on the CSE(the “Company” or “Enertopia”) is pleased to announce the following lithium project testing update.

The Company has been and continues to run the following series of tests, grain sizing and lithium grades per grain sizing, pre-strip reagent testing on impurity levels in the Upper Oxide and Reduced drilled horizons from our Clayton Valley, Nevada project.

The Company is pleased to report the sizing and assay results have been received. The testing was broken into three main zones. Zone 1 consisted of material from the upper oxide horizon from downhole intervals between 32 feet to 118 feet in depth. Zone 2 the upper reduced zone with material taken from 105 feet to 185 feet in depth. Zone 3 the main reduced zone with material from 192 feet to 347 feet in depth. The sample size for each test was 200g. The first test was sizing the 200g of dry material and assaying. The second test was to wet the material with tap water pH 7.2 and then do a second size sorting and assaying.

The goals of the sorting and assaying tests were to determine the distribution of size fraction and Li grade per size fraction first on the dry fraction and secondly on the wet fraction. Below are the testing results conducted by Basemet Labs from Kamloops, BC, and assay results from ALS Labs from Vancouver, BC. Note sizing of 20um or larger looks and feels like fine silty sand, while the size fraction smaller than 20um looks and feels like fine clay.

Key takeaways from the dry fractions sorting and assay tests, all three zones had dry fractions of 20um or larger above 95% material content. Grades between the two fraction sizes, for the most part, were very close. From a mining perspective, presorting of dry material may not be needed under a mining scenario at this time.

Key takeaways from the wet fractions sorting and assay tests had one similarity in that the size fraction flipped in that most of the material greater than 95% fell into the small fraction size of under 20um. The wet tests resulted in a material difference in grade between the fraction size.

From a process perspective, the potential to process less material at a higher Li grade could be very significant.

These results will be followed up as we move forward as they could be material in the processing flow chart under a potential production scenario.

We look forward to our solution testing results in the coming days, the company is now focused on the next steps of our solutions to be run through the column leach resin tests that will start in early June.

It is too early in the Company’s development to specify an exact timeline or particular production equipment, but we have, at this point, every indication that our goal is achievable at a much lower capital cost than the industry has recently been accustomed to dealing with.

Our pre-pH adjustmentshave demonstrated positive outcomes as contaminant minerals are greatly reduced allowing for a cleaner synthetic lithium brine to be processed using off the shelf technologies and variants developed by others and Entertopia.

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
