Exhibit 99.6
CERTIFICATE OF STEPHEN WEST
I, Stephen West, P. Eng., of Flin Flon, Manitoba, do hereby certify that:
1. I am currently employed as Superintendent, Environmental Control with HudBay Minerals Inc. (the “Issuer”), P.O. Box 1500, Flin Flon, Manitoba, Canada, R8A 1N9.
2. I graduated from University of Guelph with a Bachelor of Science in Water Resource Engineering in 1978.
3. I am a member in good standing of the Association of Professional Engineers & Geoscientists of the Province of Manitoba, Registration #5945.
4. I have practiced my profession continuously for almost 34 years and have been involved with environmental programs related to all aspects of mine and mill tailing impoundment operations.
5. 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 fulfill the requirements to be a “qualified person” for the purpose of NI 43-101.
6. I have prepared, with the assistance of other contributing colleagues, and am responsible for section 20 of the technical report titled “Technical Report 777 Mine, Flin Flon, Manitoba, Canada”, dated October 15, 2012 (the “Technical Report”). I visited the mill tailings impoundment area and monitored the waste water from the 777 Mine on May 8, 2012.
7. As of the date of this certificate, to the best of my knowledge, information and belief, the parts of the Technical Report that I am responsible for contain all scientific and technical information that is required to be disclosed to make the Technical Report not misleading.
8. I have been involved with the Flin Flon tailings impoundment area and waste water monitoring since 1981.
9. I am not independent of the Issuer. Since I am an employee of the Issuer, a producing issuer, I fall under subsection 5.3 (3) of NI 43-101 where “A technical report required to be filed by a producing issuer is not required to be prepared by or under the supervision of an independent qualified person.”
10. I have read National Instrument 43-101 and Form 43-101F1, and the Technical Report has been prepared in compliance with the instrument and form.
11. I consent to the filing of the Technical Report with any stock exchange, securities commission or other regulatory authority and any publication by them, including
electronic publication in the public company files on their websites accessible by the public, of the Technical Report.
