Mr. Gilbride adds over 17 years experience in mining and civil engineering projects, with emphasis on underground geomechanical design and resource evaluation. Engineering experience includes geotechnical characterization, laboratory testing, numerical modeling, geotechnical instrumentation, ventilation surveying and design, mine economic evaluation, conventional and geostatistical ore reserve estimation, mine planning and feasibility evaluation, and certified resource reporting. Clientele include mine operators in hard-rock, soft-rock, coal, industrial minerals, and stone, and the nuclear waste industry. Geomechanical engineering experience includes ground support design, barrier and yield pillar design, stability evaluation, ground subsidence analysis, mine sequencing, shaft and decline design, entry orientation, multi-seam design, longwall shield capacity selection, underground storage bin design, ground failure investigation, in-situ stress determination, geological hazards identification, and slope stability analysis. Extensive geomechanical modeling experience using two- and three-dimensional linear and non-linear computer codes, including EXPAREA, FLAC, FLAC3D, UDEC, and PFC3D. He has conducted resource and reserve evaluations in zinc, molybdenum, uranium, vanadium, coal, trona, and potash, under the recognized international reporting standards including 43-101, JORC, SME, and the SEC. Mr. Gilbride is a registered professional engineer in Colorado, Idaho, and the Province of Saskatchewan in Canada and an active member of SME and ASCE.
