E3 Metals Achieves Major Milestone with

Breakthrough Performance of its Proprietary

Lithium Extraction Technology

Additional testing demonstrates increased concentration of up to 100 times, resulting in

lithium grades of up to 5367 mg/L

Increased concentrations continue to yield high recoveries and low impurities

Results confirm continued advancement of our proprietary ion-exchange extraction

technology and provide continued confidence in developing towards the commercial

viability of the project

CALGARY

March 4, 2019

/CNW/ - E3 METALS CORP. (TSXV: ETMC) (FSE: OU7A) (OTC:

EEMMF) (the "Company" or "E3" or "E3 Metals") is pleased to announce it has achieved a major

milestone in the development of its proprietary Ion Exchange Lithium Extraction Technology

("Extraction Technology"). A series of tests were conducted on the sorbent incorporating the most

recent enhancements as outlined in our

December 4, 2018

news release. These enhancements have

enabled E3 to create a more robust sorbent, resulting in higher lithium concentrations of up to 5367

mg/L lithium, compared to our previous level of 1498 mg/L. Tests were conducted to demonstrate

the performance of the enhanced sorbent by concentrating 50 times and 100 times, with resulting

lithium concentrations of 3142 mg/L and 5367 mg/L, respectively. This was accomplished without

sacrificing lithium recovery and maintaining very low impurities in the concentrate feedstock.

Lithium recovery was 98% with 50 times concentration and 84% with 100 times, confirming very high

efficiency. Greater than 99% impurity removal was observed in both cases (Table 1). E3 Metals'

Extraction Technology optimization has so far demonstrated an increase in lithium concentration from

60 mg/L to over 5000 mg/L in the latest tests. Increasing the concentration through our Extraction

Technology and producing a high purity lithium concentrate feedstock, combined with the high flow

rates from the Leduc Reservoir, are key factors behind demonstrating the feasibility of the project

and moving towards a commercial lithium production flow sheet.

"This increase in concentration using our proprietary Extraction Technology is the key to unlocking

the value of our vast, yet lower grade, resource. These results move us a significant step toward

supporting E3's goal of becoming an industry leading, low-cost producer of battery grade lithium

products," commented

Chris Doornbos

, President and CEO of E3 Metals Corp. "We have

demonstrated the ability to significantly increase our lithium concentration without using additional

energy. The higher upfront concentration means less volume to handle downstream from our lithium

Extraction Technology and should reduce the energy, inputs and potentially the capital and operating

costs required to generate lithium hydroxide. These results continually demonstrate an innovative and

robust process developed by the

University of Alberta

and supported by Green Centre Canada, with

funding from Alberta Innovates."

Optimizing the performance of our proprietary Extraction Technology is a key part of E3 Metals'

larger development plan as outlined in the

September 28, 2018

news release. The ultimate goal is to

maximize the performance of the sorbent and to demonstrate it works on a commercial production

scale. This is likely to have a significant impact on the efficiencies of the overall production flow

sheet when E3's Extraction Technology is combined with other available industry technology to

produce lithium hydroxide.

To reach the target for battery grade lithium hydroxide (LiOH•H2O), lithium is refined, and impurities

removed, to reach a 99.5% or greater purity of LiOH•H2O. Removing impurities and concentrating

the lithium in a single step is critical to the overall production flow sheet. If these concentration levels

can be consistently achieved under full cycle process flow conditions and in larger field-based pilot

plant testing, the Company believes the most significant development hurdle will have been achieved.

About E3 Metals Corp.

E3 Metals is a lithium development company moving towards commercialization of lithium production

Alberta

through continued development of its proprietary Ion Exchange Lithium Extraction

Technology. E3 plans to quickly move towards the production of high purity, battery grade, lithium

hydroxide.

The Company combines a significant resource with the right technology solutions that have the

potential to deliver lithium to market from one of the best development jurisdictions in the world. Our

prolific Leduc Reservoir hosts lithium enriched brine with 6.7 million tonnes LCE inferred mineral

resource

delineated to date. The development of this resource through brine production is a well

understood venture in

Alberta

, where this brine is currently being produced to surface through

extensive oil and gas development.

While the lithium brine and hydrocarbons are mutually exclusive, the Leduc Reservoir can support the

production of brine few others can boast, with one well having the ability to bring 10,000 m3/day

(115 L/s) to surface. With an average and consistent grade of 77.4 mg/L in the Clearwater

Resource Area

, E3 Metals' proprietary Ion Exchange Lithium Extraction Technology can quickly

produce a concentrate with a grade over 5000 mg/L. With 99% of the impurities removed at the

same time and recoveries averaging 90%

, this concentrate feedstock is likely to be processed

directly utilizing conventional lithium production methods to produce high purity lithium hydroxide

(LiOH∙H2O). The Company's plans are to deliver a process facility of 10,000 tonnes/year LiOH by

2022 and continue expansion to an eventual 50,000 tonnes/year.
