E3 Lithium Announces 16.0 million tonnes Measured and Indicated Resource Upgrade

Resource Estimates

E3 Lithium Announces 16.0 million tonnes

Measured and Indicated Resource Upgrade

CALGARY, AB

,

March 21, 2023

/CNW/ - E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX:

EEMMF), "E3" or the "Company,"

Alberta's

leading lithium developer and extraction technology

innovator, today announced the upgrade of its mineral resource to Measured and Indicated (M&I).

The mineral resource upgrade includes 6.6 million tonnes (Mt) of Lithium Carbonate Equivalent (LCE)

Measured and 9.4 Mt of LCE Indicated for a total of 16.0 Mt M&I within its Bashaw District, outlined

in Table 1.

Ltd.)

"This resource upgrade is the largest of its kind in

Canada

and is significant on a global scale," said

Chris Doornbos

, President and CEO of E3 Lithium. "The amount of data and geological work

required to upgrade resources of this magnitude is significant and further increases our

understanding of the Leduc Aquifer and as a result, our technical confidence in our commercialization

plans."

Measured & Indicated Upgrade Description

The upgraded 16.0 Mt of LCE is

Canada's

largest and one of the largest Direct Lithium Extraction

brine projects and M&I mineral resources globally. According to Natural Resources Canada,

Canada

currently has an estimated 3.2 Mt of M&I lithium resources located in hard rock deposits[1].

To complete this upgrade, E3 used data gathered through its 2022 drill program, ongoing reviews

and analyses of core samples and the development of a comprehensive geological model of the

Bashaw District. This model allows for a more detailed representation of reservoir properties and

leads to a more accurate resource calculation.

The

Clearwater Area

has been modified and expanded from previous releases to include a more

representative aerial extent of the likely production zone, outlined in Figure 1. The resource outlined

within this new area represents the volume contained within the new boundary.

In addition to its M&I resources, E3 has 0.9 Mt of Inferred LCE in its

Rocky Area

. Due to the work

required and higher geological confidence provided by upgrading to M&I, it is common for the

resource to decrease in size as it increases in quality.

Consistent with E3 Lithium's prior resource estimates, the NI 43-101 Technical Report for the

Bashaw District is being prepared and will be filed on SEDAR and the Company's website within 45

days.

Mineral Resource Estimate

The resource estimate was completed by E3's multi-disciplinary team and overseen by

Daron

Abbey

, P.

Geo and Alex Haluszka

, P. Geo of Matrix Solutions Inc. acting as the Qualified Person

(QP) required by National Instrument 43-101 (NI 43-101) standards[2]. A 3-dimensional geological

model was developed using Petrel™, a resource estimation software used to estimate volumetrics

and grade distribution, to generate an improved understanding of the Leduc Reservoir in the

Company's Bashaw District. The geological model included the following reservoir characteristics:

porosity, permeability, pressure and lithium concentrations. The 3D geological model was then

utilized to evaluate scenarios of connected porosity that comprise the resource volume in the model

domain. The mineral resource estimate benefited from a considerable amount of data collected by

E3 over the past six years and compiled from the oil and gas industry, which is made public as a

matter of normal practice by the Government of

Alberta

.

Key data sets used to determine aquifer brine parameters in the resource area, and their

contribution to the resource estimate, are summarized below.

Data Source

Contribution to Resource Estimate

E3's 2022 Production Test

Pressure validation; brine analysis; permeability estimation; flow system continuity

E3's 2022 Evaluation Well Program

Core analysis porosity (total & effective), total porosity & permeability measurements; facies descriptions; downhole wireline logs

(lithology, total & effective porosity); lithium concentrations

Public Well Data (logs, core, drill stem tests)

Formation tops, depths, and thicknesses; facies interpretations; lithology, porosity (total & effective); permeability measurements

Historical Production and Injection Volumes

(hydrocarbons and brine)

Regional pressure measurements supporting continuity, rate data supporting producibility and injectivity

E3's 2017-2022 Sampling Programs

Lithium concentrations

The concentration of lithium within the consolidated Bashaw District is relatively consistent laterally

and vertically across the aquifer. E3 has collected sufficient data to demonstrate this statistically and

this information was used to assign lithium grade in the geological model. The P50 lithium grade

value is 74.5 mg/L, statistically derived from 85 brine samples from the Leduc Aquifer in the Bashaw

District and was applied for both the Measured and Indicated resources described below. All lithium

brine analyses were completed by an ISO certified 3rd party laboratory and followed a strict chain

of custody process.

The methodology used to estimate the resource volumes using the 3D geological model is as

follows:

1.

Total Original Lithium in Place:

a.

Reported brine-filled, connected pore volume, above a 2% effective porosity cut-off, with a lithium measurement from 50 equiprobable realizations

b.

Calculated P50 volume from the above, less the original hydrocarbon pore volumes

2.

Measured Lithium in Place:

a.

Reported brine-filled, connected pore volume, above a 6% effective porosity cut-off, with a lithium measurement, from 50 equiprobable realizations

b.

Calculated P50 volume from the above, less the original hydrocarbon pore volumes

3.

Indicated Lithium in Place:

a.

The total original lithium in place, less the measured lithium in place

Using the methodology described above, the total Indicated and Measured resource estimate for the

Bashaw District is 3,006,000 tonnes of lithium, which equates to 16,003,000 tonnes of lithium

carbonate equivalent (LCE)[3].

The Indicated portion of the resource is 9,404,000 tonnes LCE and is classified as indicated due to

the evidence being sufficient to assume geological, grade, and quality continuity between points of

observation. This confidence is sufficient to allow the application of modifying factors in sufficient

detail to support mine planning and final evaluation of the economic viability of the resource.

The Measured portion of the resource is 6,598,000 tonnes LCE and is classified as measured due

to the geological evidence being sufficient to confirm geological, grade and quality continuity

between points of observation. This confidence is sufficient to allow the application of modifying

factors in sufficient detail to support mine planning and final evaluation of economic viability of a

resource.
