SENIOR RESOURCE GEOLOGIST JULY 2005 – SEPTEMBER 2023 Stantec Consulting Ltd. - Mining Group. Chandler, Arizona Senior Resource Geologist working for a consulting firm specializing in all aspects of underground and surface mining operations and design with both domestic and international clients. Primary responsibilities included the review of geological and mineral resource data with the client in the field and in the office, then constructing or validating associated mineral resource estimates. Projects have involved data review, validation, and resource modeling as a QP or CP to ensure 43-101, S-K 1300, and JORC compliance. This work involved review of data collection, analytical methods, and sample security measures used to check for compliance with industry acceptable standards. Additional tasks include the review and design of infrastructure and access drifts to developing mines. Recent clients and project involvement includes,

• McEwen Mining – QP for geology and resource sections of S-K 1300 Technical Report for the PEA of the Los Azules Deposit in Argentina.

• Arizona Sonoran Copper Company – QP for geology and resource sections of original maiden resource, then multiple PEAs, and most recently a PFS level NI-43101 Technical Report for the Cactus and Parks/Salyer deposits near Casa Grande, Arizona.

• Euro Lithium + Borates – Site visit and generation of a NI 43-101 compliant maiden resource for the Valjevo deposit in Serbia.

• American West Metals Ltd. – Site visit, data review, and preliminary resource estimation for the West Desert Zinc, Copper, and Indium deposit near Delta, Utah.
