Bronco Creek Exploration Team



David A. Johnson, PhD
Position: President

David Johnson has more than 17 years of industry experience in generative exploration and consulting for major mining companies. David is a co-founder of Bronco Creek Exploration, where his current responsibilities include business development, managing day-to-day company affairs, target generation, land acquisition, and overseeing project activities. David specializes in developing new exploration ideas and opportunities utilizing innovative geologic approaches. He excels in designing, implementing, and managing broad-based mineral exploration programs, ranging from region-selection to property evaluation. Past research activities focused on the application of ore genesis and mass-transfer to mineral exploration where he co-developed a new deposit model for Fe-oxide-Cu-Au (IOCG) deposits and co-authored review papers on porphyry and IOCG deposits for the Economic Geology 100th Anniversary Volume. David graduated from The Colorado College in 1988 with a B.A. in geology, and later earned his PhD from the University of Arizona in 2000. Current exploration activities are focused on broad-based mineral exploration programs in North America.

Eric Jensen, PhD
Position: Co-Founder

Eric Jensen has 15 years of industry experience including positions as mine geologist, mine-site exploration geologist, grassroots exploration geologist, and as a consultant to several major mining companies. Eric is a co-founder of Bronco Creek Exploration, and currently serves as Chief Geologist of Eurasian Minerals. He has extensive experience in the planning and implementation of regional-scale sampling programs and geologic evaluations of properties and prospective terranes. He has relevant exploration, research and academic experience in mineral deposits related to alkaline magmatism, “high- and low-sulfidation” epithermal gold deposits, porphyry-style deposits, mesothermal lode gold systems, and Fe-oxide-Cu-Au systems. Eric graduated from Carleton College in Northfield, Minnesota in 1993 with a B.A. in Geology, and received his PhD in Economic Geology from the Center for Mineral Resources at the University of Arizona in 2003.

Location of selected past exploration projects and programs:
  • Porphyry-style Cu-Mo (-Au) mineralization, Southwestern United States
  • Gold deposits related to alkaline intrusive systems Rocky Mountains/North American Cordillera
  • Gold deposits in the Black Hills uplift, Wyoming/South Dakota
  • Mineral deposits associated with alkaline intrusive centers, Northeastern Mexico
  • High- and low-sulfidation gold deposits and magmatic-hydrothermal mineral deposits, Peruvian Andes
  • Mesothermal lode gold systems and Fe-oxide-Cu-Au-REE deposits, Bolivian Altiplano
  • Fe-oxide-Cu-Au-REE deposits, central Chile

David Maher, PhD
Position: Vice President Target Generation

David Maher has 16 years of mineral exploration and mine geology experience in Arizona and Nevada. He graduated with a B.S. in geology from the University of Wisconsin-Oshkosh in 1991. He commenced his M.S. studies with John Dilles in 1991 and began working with Eric Seedorff in the Robinson  District in Ely, Nevada, in 1992. Robinson is a highly extended porphyry copper system with an excellent geologic data set: more than 125 years of geologic mapping and well over 4 million feet of drilling. The well-constrained geology and structural relationships at Robinson strongly influenced his subsequent geologic interests in the structural dismemberment of porphyry copper deposits, including research and application to mine modeling and mineral exploration. David graduated with an M.S. in economic geology from Oregon State University in 1995 and moved to Tucson to work in copper exploration and mine modeling with Magma Copper Co, BHP, and other companies in Arizona, Nevada, and northern Sonora, Mexico. In 2001, he enrolled in the PhD program at the University of Arizona to further study middle Tertiary extension of Laramide porphyry copper systems in southeast Arizona with professors Mark Barton and Eric Seedorff. David defended his dissertation and joined the BCE team in December 2007.

 


Directors

David M. Cole

Position: Director
David Cole has 24 years of industry experience, and currently serves as President, CEO, and Director of Eurasian Minerals Inc. David is a founding shareholder and Director of Standard Uranium Corp. which was acquired by Energy Metals Corp. in 2006; and he served as a Director on the Energy Metals board until it was sold to Uranium One. Previously, at Newmont Mining Corporation, he held a number of management and senior geologic positions, gaining extensive global experience as a project, mine, and generative exploration geologist in Nevada, Southeast Asia, South America, Europe, and Central Asia. David’s success as part of Newmont's exploration team includes contributions at the world class Carlin Trend, Yanacocha, and Minihasa mines. Subsequently, he established and managed Newmont's exploration programs in Turkey while also identifying early stage acquisition targets in Eastern Europe. David specializes in developing new exploration ideas and opportunities, based upon solid technical expertise coupled with a keen business sense. David is also a successful private investor with an avid interest in the markets. He studied under Dr. Tommy Thompson at Colorado State University, earning an M.S. in Geology.

 


Advisors and Affiliates

Mark D. Barton, PhD 
Position: Advisor

Mark Barton has been instrumental in driving innovative research applied to ore deposits in North and South America for nearly 30 years. Currently a professor of Economic Geology at the University of Arizona, he is also the director of the Center for Mineral Resources and a cofounder of the Institute for Mineral Resources. Dr. Barton is a renowned economic geologist and petrologist, a Society of Economic Geology Lindgren award winner, and author of numerous papers including landmark reviews on ore deposits and metallogeny. Mark’s current research focuses on magmatic evolution and its links with hydrothermal deposits, the role of surficial conditions in mass transfer systems, and the regional and global patterns of mineralization through time. His studies have centered on southwestern North America and Pacific Rim porphyry, skarn, Fe-oxide(-REE-Cu-Au), and other igneous-related systems. Collaborative research in progress where he has a leading role includes: porphyry Cu Lifecycles in southwestern North America and its broader crustal context; regional geologic framework and origin of Carlin-type gold deposits; characteristics and origin of Fe-oxide(REE-Cu-Au) mineralization; granite petrogenesis and lithophile element mineralization in the Great Basin; and metallogenic synthesis of Mexico and adjoining regions. Mark earned B.S. and M.S. degrees in Geology from Virginia Tech, and a PhD degree in Geology from the University of Chicago. 

Eric Seedorff, PhD
Position: Advisor
Eric Seedorff has contributed his expertise in porphyry-related deposits, extensional tectonics, and hydrothermal alteration-mineralization to the mineral exploration and development industries for nearly 30 years. Eric currently is a professor and holder of the Lowell Chair in Economic Geology in the Department of Geosciences, University of Arizona, where he leads a post-graduate education and training program for geologists in the minerals industry. Immediately prior to becoming a faculty member, Eric was an entrepreneur for two years.
