Kelowna, British Columbia--(Newsfile Corp. - June 20, 2024) - Enertopia Corporation (OTCQB: ENRT) (CSE: ENRT) ("Enertopia'' or the "Company") a company focused on building shareholder value through a combination of our Nevada lithium claims, intellectual property, & pending patents in the green technology space, is very pleased to provide the following lithium project update.

The Company is pleased to report the second phase of metallurgical testing is underway, and is expected to be completed before the end of August. Earlier this year, as per our May 29th press release, the Company initiated our first round of 3rd party metallurgical testing for the WT Lithium Project west of Tonopah, NV at Kappes, Cassiday & Associates ("KC&A") based in Reno, NV.

Goals for the second phase metallurgical test work are summarized below:

• Feed preparation/beneficiation - coarse material (+75 micron) expecting a reduction in material mass, increase in lithium grade and decrease in net acid-consumption per mg of lithium put into solution.
• Further analysis on leaching time and temperature testing for reduced acid consumption.
• Three roast tests with subsequent water leach tests of the calcined products

Below summary of the first phase of metallurgical test work press released on May 29, 2024.

Highlights of the process development and laboratory work completed to-date:

• HCL acid leaching - extraction of 97% lithium is achieved with 4 hours of retention time at 60degreeC.
• HCL acid leaching - extraction of 91% lithium is achieved with 1 hour of retention time at 60degreeC.
• Sulphuric acid leaching - extraction of 91% lithium is achieved with 4 hours of retention time at 60degreeC.
• Sulphuric acid leaching - extraction of 79% lithium is achieved with 1 hour of retention time at 60degreeC.
• Distilled water leaching for baseline test - extraction of 1% lithium is achieved with 24 hours or retention time at 23 degrees C.

Key takeaways:

• Solution leaching results show lithium is readily leachable from the hosted claystone rock at our 100% WT lithium project.
• Overall lithium recovery is a function of time in retention, temperature, and type of acid used.
• Measured HCL acid consumed was 12% less than Sulphuric acid.
• Measured lithium into solution increased by 11% using HCL acid vs Sulphuric acid in 1 hour retention tests.

"The Enertopia team of consultants looks forward to continuing to move ahead on our developing Lithium and technology assets." Stated President Robert McAllister.
