CERTIFICATE OF QUALIFIED PERSON
I, Scott Swinden, do hereby certify that:
1. I am a Principal Geoscience Consultant of: Swinden Geoscience Consultants Ltd 224 Main St
Wolfville, Nova Scotia
B4P 1C4
Canada
- This certificate applies to the technical report titled "Namibia Critical Metals Inc., Lofdal Heavy Rare Earths Project, Namibia, NI 43-101 Technical Report - 05 April 2024 Mineral Resource Estimate", that has an effective date of 05 April 2024 and a report date of 21 May 2024 (the Technical Report).
- I graduated with a BSc (Hons) degree in Geology from Dalhousie University in 1970. In addition, I obtained a Master of Science degree in Geology from Memorial University of Newfoundland and Labrador in 1975 and Ph.D. in Earth Sciences from Memorial University of Newfoundland and Labrador in 1988.
- I am a registered Professional Geologist (P. Geo.) with the Association of Professional Engineers and Geoscientists of Nova Scotia.
- I have worked as a geologist for a total of 45 years, including exploration for base and precious metals and rare metals (including the rare earth elements), as a research scientist for provincial and federal geological surveys, and as manager and executive for provincial geological surveys. In the latter role, I was responsible for mineral resource programs (including programs focussed on Rare Earth Elements) throughout Newfoundland and Labrador from 1988 to 1996. From 2010 to the present, I have specialized in the study and exploration of Rare Earth Deposits. I explored for REE in various parts of Namibia. I was part of the discovery team at the Lofdal deposit and led the geological mapping and geological modelling of the deposit. I have worked at a number of other REE prospects including Swarboisdrift (Kunene aea), Epembe (Ta-Nb-REE in carbonatite), Marinkas Quellen). I have taught mineral deposits including the geology of Rare Earth Deposits to 4th year undergraduates at Dalhousie and Acadia Universities. I have recently served as a member of the Expert Council for the HiTech AlkCarb project, a European Union project investigating geomodels for REE deposits. I believe my experience in operating and managing REE exploration projects, studying REE deposits and teaching about REE deposits, make me a Qualified Person for a REE project.
- I have read the definition of "Qualified Person" set out in National Instrument 43-101 (NI 43-101) and certify that by reason of my education, affiliation with a professional association (as defined in NI 43-101) and past relevant work experience, I fulfil the requirements to be a "Qualified Person" for the purposes of NI 43-101.
- I visited the Lofdal Property for 14 days from 29 May to 11 June 2014, for 1 days on July 31, 2017, and for 1 day on April 25, 2018.
- I am responsible for the preparation of items 4 to 9 and co-responsible for, the preparation of item 1, 2 and 24 to 27 of the Technical Report.
- I have been involved with the property that is the subject of the Technical Report as a paid, independent geoscience consultant since July 2010. All prior involvement is with the current issuer at various stages of the project for which remuneration has been received as an independent consultant that is not contingent on the outcome of the study work and did not involve management of the project.
- I am not aware of any material fact or material change with respect to the subject matter of the Technical Report that is not reflected in the Technical Report, the omission to disclose which makes the Technical Report misleading.
- I am independent of the issuer according to the definition of independence described in section 1.5 of National Instrument 43-101.
- I have read National Instrument 43-101 and Form 43-101F1 and, as of the date of this certificate, to the best of my knowledge, information and belief, those portions of the Technical Report for which I am responsible have been prepared in compliance with that instrument and form.
- I consent to the filing of the Technical Report with any stock exchange and other regulatory authority and any publication by them for regulatory purposes, including electronic publication in the public company files on their websites accessible by the public, of the Technical Report.
