Throughout his long and illustrious career, Dr. Juhas has worked in virtually every facet of the mining industry. Dr. Juhas earned his Honors Bachelor of Science and Ph.D (Economic Geology) degrees from the University of Manitoba. The field seasons in the early years of his career were spent with the Manitoba Government Geological survey in mapping and exploring complexly metamorphosed Precambrian terranes, and with major companies – Inco, Union Carbide, Cominco – in searching for copper-nickel, copper-zinc, and gold deposits in the Canadian Shield, and for gold-silver and base metals in the Cordillera of British Columbia.

He then spent 17 years in international exploration with the TexasGulf organization as an exploration manager and ultimately as corporate chief geologist, during which time he also served as vice-president and director of a Latin American exploration subsidiary

Since resigning from Texasgulf, Dr. Juhas has mainly served as a consultant to numerous junior, intermediate and major mining and exploration companies, involved in the generation, evaluation, financing and marketing of exploration projects. He has written numerous reports for mining and service companies, individuals, stock exchanges and accounting firms. He has also served as an officer and director of junior exploration companies such as AVF Minerals Ltd., Mercator Minerals Ltd., and NovaGold Resources Inc.

Dr. Juhas is a member of the American Institute of Professional Geologists, the Canadian Institute of Mining and Metallurgy, the Denver Region Exploration Geologists Society (DREGS), the Society of Economic Geologists (SEG), and the Society of Mining Engineers (SME). He is a past-president of the Society of Economic Geologists Foundation, and was a founder and past president of DREGS.

Dr. Juhas also served several years behind the scenes as liaison person regarding matters of mutual concern between SEG and SME. He has been honored as a traveling “Henry Krumb Lecturer” by the Society of Mining Engineers, and he also served as the “Jack Gallagher Visiting Scientist”, a mentoring program for geologists at Canadian universities.

Dr. Juhas is also involved with volunteer work. Much of Dr. Juhas’ volunteer interests revolve around the education of young people. As such, he is a long time member of the SEG Foundation’s Student Grant Committee, which annually makes dozens of major grants to deserving economic geology students worldwide. He also serves on the SME GEM Committee, which has an interest in educating teachers and students about the importance of mining in their lives.
