Technical Report
I am registered as a Professional Geoscientist with Engineers and Geoscientists British Columbia. I graduated with a B.Sc. degree in geology from University of British Columbia in 2008. I completed the Applied Geostatistics Citation Program with the University of Alberta in 2014 and the specialized training cycle in mining Geostatistics with the Mines Paris and Geovariances in 2022.
I have practiced my profession for 16 years. I have been involved in exploration drilling programs involving core logging, sampling, QAQC, and database validation. I have conducted onsite grade control and management of mine operation crews for an open pit mine in eastern Canada. I have conducted audits and due diligence exercises on geological models, sampling databases, drill hole spacing studies, preparation of resource models, validation of mineral resource estimates, mineral resource estimates and conditional simulation studies on advanced mining studies, and active mine operations.
As a result of my experience and qualifications, I am a Qualified Person as defined in National Instrument 43
101 Standards of Disclosure for Mineral Projects (NI 43
101), for those sections of the Technical Report that I am responsible for preparing.
I visited the El Quevar property between September 24 and September 27, 2024.
I am responsible for Sections 1.1-1.5, 1.7-1.9, 1.11; Sections 2-12; Sections 14-24; Sections 25.1-25.4,
25.6, 25.7; Section 26 and Section 27 of the Technical Report. I am independent of Argenta Silver Corp as independence is described by Section 1.5 of NI 43-101. I have had no previous involvement with the El Quevar property. I have read NI 43-101, and the sections of the Technical Report that I am responsible for have been prepared in compliance with that Instrument. As of the effective date of the Technical Report, to the best of my knowledge, information and belief, the sections of the Technical Report for which I am responsible for preparing contain all scientific and technical information that is required to be disclosed to make those sections of the Technical Report not misleading.
