To accompany the Report entitled “NI 43-101 Technical Report Preliminary Economic Assessment Clearwater Lithium Project” (the “Technical Report”):

Effective Date: November 16, 2020 Issue Date: December 21, 2020 Amended Date: September 17, 2021

I, Gordon MacMillan , P.Geol., hereby state that:

1. I am currently engaged as a Hydrogeological Consultant;

2. I am a graduate of the University of Calgary with a Bachelor of Science in Applied and Environmental Geology (1998);

3. I am a Registered Professional Geologist through the Association of Professional Engineers and Geoscientists of Alberta, Membership Number 63537;

4. I have practiced as a professional in hydrogeology since 2000 and have 20 years of experience in mining, water supply, water injection, and the construction and calibration of numerical models of subsurface flow and solute migration. My experience includes work in the lithium industry focussed on evaluating aquifer continuity, potential pumping rates, and estimating the mass of lithium in the subsurface. I have performed three-dimensional numerical modelling of groundwater flow, solute transport and heat flow. I have been involved in multiple numerical modelling investigations of Alberta’s Keg River Formation and Leduc Formation reefs for the purposes of water production, wastewater injection, and solute migration. I have completed various investigations into the mass balance of local and regional groundwater flow systems. I have published multiple peer-reviewed papers on the design of water well networks. I have worked with multi-discipline teams to develop and model detailed models of large-scale solute migration. I have prepared resource estimations for mineral projects;

5. I have read the definition of “Qualified Persons” set out in National Instrument 43-101 Standards of Disclosure for Mineral Projects (the “Instrument” or “NI 43-101”) and certify that by reason, I fulfill the requirements to be a “Qualified Person” for the purposes of NI 43-101;

6. I am responsible for the preparation of Sections 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, and 23 of the report entitled “NI 43-101 Technical Report Preliminary Economic Assessment Clearwater Lithium Project” with effective date of November 16, 2020 and an amended date of September 17, 2021 (the “Technical Report”);

7. I have reviewed the field sampling Standard Operating Procedure (SOP) and the Laboratory Testing SOP developed by E3 Metals to ensure consistent and accurate sample collection and analysis. I have reviewed the Quality Assurance/Quality Control results provided by E3 Metals and reviewed the reports provided for each lithium sample by the laboratory on the property that is the subject of the Technical Report (the “Property”).

8. I visited the site location on August 27, 2021 and witnessed samples collected with E3 Metals’ Standard Operating Procedure (SOP). I have also witnessed E3 Metals Corporation’s collection of

field samples on March 23, 2018 site visit to the Exshaw West Resource Area, located on a contiguous portion of the Leduc reef, north of the CCRA.

1. I was responsible for Section 14 of the report entitled “NI 43-101 Technical Report LITHIUM RESOURCE ESTIMATE for the CENTRAL CLEARWATER PROPERTY SOUTH-CENTRAL ALBERTA, CANADA” with the effective date October 27, 2017.

2. At the effective date of the Technical Report, to the best of my knowledge, information, and belief, the Technical Report, or part that I am responsible for, contains all scientific and technical information that is required to be disclosed to make the Technical Report not misleading.

3. I do not hold, nor do I expect to receive, any securities or any other interest in any corporate entity, private or public, with interests in the properties that are the subject of this report or in the properties themselves, nor do I have any business relationship with any such entity apart from a professional consulting relationship with the issuer, nor to the best of my knowledge do I have any interest in any securities of any corporate entity with adjacent properties to the subject properties.

4. I am independent of E3 Metals Corporation according to the criteria stated in Section 1.5 of the Instrument;

5. I have read NI 43-101 and Form NI 43-101F1 and the Technical Report has been prepared in compliance with that instrument and form.

6. I consent to the public filing of the Technical Report titled “NI 43-101 Technical Report Preliminary Economic Assessment Clearwater Lithium Project” (the “Technical Report”) by E3 Metals Corp. I also consent to any extracts from or a summary of the Technical Report in any type of disclosure document with any stock exchanges or other regulatory authority and any publication by them, including electronic publication in the public company files on the websites accessible by the public, of the Technical Report of E3 Metals Corp.
