David A. Johnson, PhD
Senior Geologist, President

Dr. Johnson has more than 16 years of industry experience in generative exploration and consulting for major mining companies. David Johnson 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. Dr. Johnson specializes in developing new exploration ideas and opportunities utilizing innovative geologic approaches. Dr. Johnson 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. Dr. Johnson 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
Senior Geologist, Vice President

Dr. Jensen has 11 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. He has extensive experience in the planning and implementation of regional-scale sampling programs and geologic evaluations of properties and prospective terranes. Current activities include managing day-to-day business affairs of Bronco Creek Exploration, including oversight of target generation, business development, land acquisition, project advancement and drill programs. Dr. Jensen is a co-founder of Bronco Creek Exploration, and 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.

Dr. Jensen 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 & 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

Senior Geologist, Vice President Target Generation

Dr. Maher has 15 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. He 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. He defended his dissertation and joined the BCE team in December 2007.

Erik Flesch
Geologist, Project Advancement Manager

Mr. Flesch brings extensive experience as a project and team leader in sales, publishing, journalism, the arts, and the minerals industry in the United States and the Russian Federation, and has a passion for organizations that think outside the box. He began his geological career in 2005 after earning a Bachelor of Science degree with a concentration in economic geology from the University of Arizona. His undergraduate research focused on mapping deep-distal styles (sodic-calcic) of alteration in the Sierrita mining district, and he contributed to Center for Mineral Resources age-dating efforts on Laramide porphyry systems. Subsequently, he worked for two years as an ore-control and mine geologist at Morenci, Arizona, where his experience modeling and routing ore in a world-class supergene-enriched Laramide porphyry copper-molybdenum district was enhanced by the operational and business-organizational opportunities at what was Phelps Dodge's flagship and the largest open-pit operation in North America. During his tenure with Bronco Creek Exploration Inc., Mr. Flesch has managed the permitting, contracting, regulatory compliance, and other project advancement responsibilities for exploration projects, and serves as a project geologist. In a business development capacity, he assists in handling company legal and business affairs and has been instrumental in establishing relationships with international exploration companies that has led to the formation of several business partnerships.
