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.

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.

Erik Flesch

Position: Project Advancement Manager, Geologist
A passion for organizations that think outside the box brought Erik Flesch to Bronco Creek Exploration, where he advances exploration projects from concept to realization through management of lands, permitting, contracting, budgeting and regulatory compliance, as well as serving as a project geologist. In a business development capacity, he promotes investor and public relations, and develops new exploration partnerships with international mining, exploration and capital corporations.

After gaining a breadth of experience as a project and team leader in the United States and the Russian Federation in the fields of business, including sales, marketing and advertising; communications, including journalism and publishing; and the arts, including architectural interpretation and preservation, Erik earned a B.S. in geosciences with a concentration in economic geology from the University of Arizona in 2005. His undergraduate research focused on Laramide porphyry copper systems, mapping deep-distal styles (sodic-calcic) of hydrothermal alteration in the Sierrita mining district, and contributing to Center for Mineral Resources U-Pb age-dating efforts on southern Arizona porphyry deposits. Subsequently, he worked as an ore-control geologist at Morenci, Arizona, where his experience included logging, mapping, modeling, and routing ore in a world-class supergene-enriched porphyry copper-molybdenum district at Phelps Dodge's (now Freeport-McMoRan Copper & Gold) flagship operation. Erik joined the Bronco Creek Exploration team in May 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.
