JOHN WELSH
Sr. Prinipal, Mining.
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
P.E., P.L.S. (Ca) – Sr. Principal, Civil
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.

Douglas Willis
C.P.G. – Sr. Geologist
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.

Ed Phariss
P.E, C.E.M.- Sr. Civil/Geotechnical Engineer
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
PhD- Principal Metalurgist
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.
