Welsh Hagen is a full service Mining, Civil and Environmental firm.

Mr. Welsh has over 40 years experience in engineering and construction of major projects. He has been in charge of design and construction of a major tailings dam with a budget of $35 million (considered to be $150 million in 2014 dollars), and managed operation of three tailings dams for a molybdenum mine in Colorado. Mr. Welsh has been the lead geotechnical engineer and design manager for major tailings dams and water control facilities in the western U.S. and Central America. He has been the lead design professional on large earth dams for water treated sewage treatment plant effluent, and mine waste containment. Several of his dam designs have exceeded 500 feet in height and many of the impoundments were lined with geomembranes for minimizing seepage losses. Several of the projects included the design management of major water diversion systems, pumping plants, and civil works. He has managed field engineering and quality assurance teams during the construction of these facilities. Mr. Welsh has been an independent contractor for the construction of numerous earthwork projects – primarily building chemical containment and waste disposal facilities. His projects included over 50 million square feet of HDPE lined heap leach pads, tailings dams, access roads, flood diversion facilities, contract mining, production of aggregates, and general site work for structures. Mr. Welsh has also managed numerous reclamation projects involving multidisciplinary tasks including treatment of acid mine drainage, heap leach pad detoxification, land application of process fluids, re-contouring waste rock dumps, demolition of structures, replacing topsoil, re-vegetation, and monitoring. Mr. Welsh has designed closure plans for existing and abandoned mines and has prepared numerous cost estimates for determining reclamation bond amounts to meet state and federal requirements.

David Hagen is the principal engineering manager of the Reno operations, bringing over 12 years of civil engineering experience in the Northern Nevada and California areas. His experience includes providing record engineering services for many projects in Northern Nevada Counties requiring hydrology and hydraulic reports, incorporating local Storm Water Management Manuals and civil engineering design incorporating the Orange Book Standard Specifications for Public Works Construction. Projects were coordinated with the various Department of Public Works (DPW) staff for review and permitting. As a consultant, Mr. Hagen has been available to assist the community with presentation and assessments of the consistency of projects with local plans and planning standards. Mr. Hagen’s expertise lies in civil site development, water quality and erosion control, hydrology/hydraulics, surveying and Nevada Department of Environmental Protection (NDEP) and Tahoe Regional Planning Agency (TRPA) codes and regulations. His past project experience includes preparation of scopes of work, proposals, civil design, drainage studies, water quality analysis, erosion control/restoration technology; hydrologic and hydraulic design; design and development of site grading, drainage, erosion control, and infrastructure plans; Federal Emergency Management Agency (FEMA) Letter of Map Revisions; surveying technician, and surveying crew chief. Mr. Hagen is skilled with many hydrologic and hydraulic modeling software programs, civil design and surveying programs, sedimentation analysis, hydrologic modeling and hydraulic analysis, water quality design, monitoring, and maintenance plans.

Mr. Willis is a certified professional geologist with over 12 years experience in the mineral exploration and mining industry. After receiving his Bachelor of Science Degree in Geology from California State University, Chico in 1987, Mr. Willis began a 7-year career with the Great Basin Exploration Division of ASARCO Inc. Mr. Willis conducted reconnaissance and development mineral exploration, property evaluations, land status evaluations and drill program supervision throughout the western United States. After 13 years in the land surveying industry, Mr. Willis joined Welsh Hagen Associates in 2008. Mr. Willis’ expertise is in the preparation of NI 43-101 Technical Reports. He has contributed to and authored Technical Reports, including Preliminary Economic Assessments and Pre- feasibility Studies, on multiple exploration and development stage properties in the western United States. Mr. Willis’ forte at Welsh Hagen Associates also includes the preparation of State and Federal mining and exploration permit applications including NEPA compliance documents, water pollution control permit applications, plans of operation, reclamation plans, notice level exploration permits and land status evaluations.

Mr. Hubbard has 26 years of progressive Project Management, Group Management, Engineering Geology, and Hydrogeology experience for large projects in the Western US. Most recently, Mr. Hubbard served as Senior Engineering Geologist and Field Task Leader for the Truckee Meadows Flood Control Project in Washoe County, Nevada. This $1 billion+ US Army Corps of Engineers (USACE) effort was the project included development of a surface and subsurface geological model of the project area and vicinity. In 2011, Mr. Hubbard performed Engineering Geology for large Wind Energy projects, including foundation, seismic and landslide investigation. Mr. Hubbard’s responsibilities included project profitability, quality and performance and client management. Other recent roles include Senior Geologist and Field Task Manager for the Martis Creek Dam geotechnical investigation. This project included development of a detailed subsurface geologic model of Martis Valley in the vicinity of the dam. Martis Creek Dam is identified by the USACE as one of the top three at-risk dams in the United States. Mr. Hubbard has served in both local and national leadership roles with the Association of Engineering Geologists and continues to do so. He is also an active member of the Nevada Earthquake Safety Council.

Dr. Carl Nesbitt is a native Nevadan and graduate from the Mackay School of Mines at the University of Nevada, Reno and the University of Michigan. Immediately after completing his baccalaureate from UNR, he worked for three years as a plant metallurgist for the Anaconda Minerals Company on the start-up and operation of a mineral concentrator and leach facility. He returned to school and completed two Masters Degrees and a PhD in Chemical and Metallurgical Engineering. Upon graduation in 1990, Dr. Nesbitt worked for Michigan Technological University as a researcher and professor of Metallurgical Engineering. Over his career at MTU, he generated numerous publications and invented patented processes which have led to two start-up companies. In 2009, Dr. Nesbitt returned to UNR, but this time as a professor of metallurgical engineering. He worked with the team that rejuvenated the Metallurgical Engineering Program in the Department of Mining Engineering, recreating a program for B.S. and M.S. students. In 2012, the first M.S. graduate was conferred. Dr. Nesbitt joins Welsh Hagen as the Principal Metallurgist. He will be responsible for metallurgical assessments, testing and process development. He will also contribute expertise in water treatment and environmental remediation processing.
