Additional sampling confirms continuity of lithium enrichment in brines across

the Leduc Reservoir, positions E3 Metals for further resource expansion

• Lithium concentrations from 11 new wells are as high as 76.9mg/L Li

• Sampling of oilfield injection wells confirms high concentrations of lithium in wastewater

• This successful sampling program is expected to contribute to the definition of an additional

inferred lithium mineral resource estimate at Exshaw West, in Q2 2018

VANCOUVER, April 26, 2018 /CNW/ - E3 METALS CORP. (TSXV: ETMC, FSE: OU7A, OTC: EEMMF)

(the "Company", "E3" or "E3 Metals") is pleased to announce results from the ongoing sampling of an

additional 11 new wells over its permit area. The results confirm the continuity of lithium enrichment in

brines throughout the Leduc Reef Complex. The expanded sampling program provides additional

resource definition potential across E3 Metals' permit areas. A resource (inferred) estimate for the

Exshaw West Area is anticipated in Q2 2018. The Exshaw West resource will add to the already defined

2.83Mt LCE in inferred resources previously defined over the Company's Clearwater and Rocky resource

areas.

Of the 11 wells sampled, 7 were from within the Leduc Formation (Woodbend Group) and 4 from within

the Nisku Formation (Winterburn Group). Both the Nisku and Leduc Formations are Devonian-aged, with

the Nisku occurring between 10-200 meters stratigraphically above the Leduc across the sampling area.

The lithium values from this sampling program range from 53.5 mg/L to 76.9 mg/L Li (Lithium) in the

Leduc Formation and 67.2 mg/L to 74.8 mg/L Li in the Nisku Formation.

In addition to brines from production wells, the Company also sampled oilfield wastewater (disposal

water) from injection wells in the Exshaw West area. Following the removal of hydrocarbons, the disposal

water is then re-injected back into the Leduc Formation, often providing pressure support in the near

vicinity of actively producing oil wells. Currently, an injection network of 13 wells is active in the Exshaw

West area. The Company obtained water samples from 2 wells within this network with results of 62.6

mg/L and 74.5 mg/L Li.

The Company continues to advance scale-up of lithium extraction technology in partnership with some of

Canada's leading (public and private) research facilities. In late 2018, the Company is planning to develop

scaled-up concentration testing equipment, with the potential to be coupled with already commercially

available polishing and production technology. The modular bench-scale prototype will be designed to

produce high purity LiOH and/or Li2CO3 for technology verification. E3 Metals plans to continue to

advance resource development in 2018 with additional sampling focused on high potential targets within

its 587,000 ha permit area.

"Sampling results continue to confirm the occurrence of lithium-enriched brines across the Leduc

Reservoir over our permit areas," said Chris Doornbos, CEO of E3 Metals. "With established geological

characteristics that ensure high rates of water deliverability and consistent lithium concentrations in

brines, the Leduc reservoir in Alberta continues to demonstrate high potential for commercial lithium

production."

About E3 Metals Corp.

E3 Metals is a Petro-Lithium development company in Alberta advancing unconventional lithium brines.

E3 Metals holds one of the world's largest lithium resources at 2.83Mt1 LCE. The Company offers a

compelling competitive advantage having access to significant infrastructure from oil and gas

development in Alberta. This has provided E3 Metals with low finding costs for the definition of its

resource from sampling wells. This infrastructure may also provide wells and pipelines for future

commercialization of a lithium production operation. The Company's immediate goal is to prove a

commercially viable chemical concentration process to unlock the value of its resource. More information
