Geologic Advisory Team

John DeDecker

John became interested in geology by way of landscape painting on the Colorado Plateau as a high school drop-out, and research telescope operator and lecturer at Lowell Observatory in Flagstaff, AZ. While in Flagstaff he developed the hypothesis for remote detection of extraterrestrial caves using thermal infrared imagery with Jut Wynne of Northern Arizona University, and Tim Titus of the USGS Astrogeology Science Center. John’s field work on the Earth-Mars Cave Detection Project’s Atacama and Mojave Desert expeditions convinced him to get a formal education in Geology.

John received his B.S. in Geology, with an emphasis on mineralogy, igneous petrology, and mathematics from North Carolina State University. He did his M.S. at UNC Chapel Hill under the advisement of Allen Glazner studying the morphology and formation mechanisms of lava tubes. John completed his Ph.D. at Colorado School of Mines under the advisement of Thomas Monecke. His doctoral research addressed several outstanding problems with current genetic models for world-class unconformity-related uranium deposits. John developed a genetic model for and proposed a new type of hydrothermally enriched carbonaceous shale-hosted vanadium deposit at Iron Point in northern Nevada, and is expanding this research into the genesis of Carlin-type gold deposits. He is a Post-doctoral Fellow at Colorado School of Mines where he is researching Au-rich VMS deposits near the Eskay Creek Mine in British Columbia.

John was the Society of Economic Geology Student Chapter President in 2015-2016, and along with his fellow SEG officers spearheaded the development of a two-week hydrothermal geochemistry and volcanology field course in the Taupo Volcanic Zone, New Zealand. He is currently flouting all dogma in economic geology while doing geological consulting as a founding partner of BOA exploration.

Dr. Quinton Hennigh, Ph.D, M.Sc

Dr. Quinton Hennigh is an internationally-renown economic geologist, with over 25 years of exploration experience and expertise with major gold mining companies such as Homestake Mining Company, Newcrest Mining Limited, and Newmont Mining Corporation where he last served as senior research geologist in 2007. He has since made a number of significant gold discoveries for Canadian exploration companies such as the 5 million oz. Springpole alkaline gold deposit near Red Lake, Ontario, for Gold Canyon Resources, and the Rattlesnake Hills gold project for Evolving Gold. He is currently Chairman and President of Novo Resources Corporation, which he helped start in 2010.

Dr. Hennigh holds a Bachelor of Science from the University of Missouri, and M.Sc. and a Ph.D. in geology and geochemistry from the Colorado School of Mines. He is a member of the Society of Economic Geologists, and the Mining and Metallurgical Society of America.

Tom Weis

Chief Geophysicist

Tom Weis has 37 years of geophysical experience in the exploration, engineering and environmental industries worldwide. He is experienced in airborne, ground and borehole geophysical techniques. Tom was formerly the Chief Geophysicist for Newmont Mining (worldwide) and Normandy Mining (Australia and worldwide)

Thomas Monecke

Thomas Monecke is an economic geologist who specializes in the formation of base and precious metal deposits in modern and ancient volcanic arcs. He has more than 25 years of experience in geological research and mineral exploration and has authored or co-authored over 100 journal papers, book chapters, government publications, and field guides during that period. Thomas graduated from the University of Freiberg, Germany, with a M.Sc. in 1996. He obtained his Ph.D. from the same university with his doctoral thesis focusing on the anatomy of a volcanogenic massive sulfide deposit in northern Australia. Between 2002 and 2008, Thomas conducted postdoctoral research at the Institute of Marine Sciences in Kiel, Germany, the University of Ottawa, and the Geological Survey of Canada on modern and ancient gold-rich volcanic-hydrothermal systems. As part of his postdoctoral research, Thomas worked on the Eskay Creek deposit in British Columbia, identifying the volcanic setting of this unusual massive sulfide deposit and studying the mineralogy of the hydrothermal alteration halo. In 2006, Thomas received the Waldemar Lindgren Award of the Society of Economic Geologists. He joined the Colorado School of Mines in 2008 where he currently teaches economic geology. Thomas runs a large research group and supervises postdoctoral fellows and graduate student working on volcanogenic massive sulfide deposits as well as epithermal and porphyry deposits around the world.
