Luis A. Vega, P.Geo

Technical Consultant & Geologist, Arizona Exploration Program

Luis Vega is a senior geologist with over 40 years of experience in working for publicly traded mining companies involved in exploration for precious and base metals His work has focused on investigation of polymetallic and porphyry copper deposits, as well as porphyry gold and sedimented hosted gold deposits throughout North America and South America. Mr. Vega is bilingual speaker in Spanish and English, and has extensive experience in business negotiations in Latin America with both private and governmental entities. He has directed exploration programs in the US, Mexico, Costa Rica, Honduras and Argentina and conducted submittal evaluations in Panama, El Salvador, Nicaragua, Colombia, Ecuador, Peru, Venezuela, Brazil, Uruguay and Chile.

He has worked for or contracted with companies such as Utah International, Duval Corporation, and Battle Mountain Gold Company, (BMGC),. While at BMGC, he established an exploration office in Chile and discovered the Angelina Porphyry copper/gold occurrence, which was sold to Gold Fields Corporation. He also participated in the discovery and definition of El Higo epithermal gold deposit in the Dominican Republic and, the Casposo Epithermal gold deposit, Argentina. In Bolivia, he supervised and conducted the early geologic work at the Kori Kollo Mine resulting in the definition of over 8 million ounces of gold resource.

While with Utah International he assisted with the definition drilling of several poly-metallic exploration projects in Utah.

During his time with Duval Corporation as head of exploration at the Mineral Park Mine near Kingman, Arizona, Mr. Vega directed the exploration programs that resulted in identification of additional copper and molybdenum reserves. He also co-established and managed the exploration operation for Duval in Argentina. Duval is a division of Pennzoil Corporation.

Mr. Vega is a co-author of several technical papers including:

Geology and Ore Deposits at Mineral Park: Mohave County, Arizona by William H. Wilkinson, Jr., Luis Alfonso Vega and Spencer R. Titley, in Advances in Geology of the Porphvrv Copper Deposits. Southwestern North America, 1980.

Exploration in Lessor Explored Countries: A Geologist's Perspective by Kirk P. Kinart and Luis Alfonso Vega; in Mining Engineering, February 1993, Vol. 45 No. 2, pp 145147.

Cuerpo Subvolcanico en la Quebrada del Chorrillo, Nueva evidencia de mineralizacion en Cordillera Frontal; San Juan, Argentina by Gustavo Sotarello, Irma Belvideri, Ivan Grassi and Luis Vega, in XVI Geological Conference Abstracts, 1997.

Mr. Vega is a member/fellow of the Society of Economic Geologists (SEG) and the American Institute of Professional Geologists (AIPG) (Ret) He holds a Bachelor of Science degree in Geology and a Master of Science in Economic Geology from the University of Arizona, Tucson.

Mr. Barr's experience includes target generation, land work, permitting and reclamation, surface and underground mapping, grid soil, mobile metallic ion (MMI) and biogeochemical sampling, and supervision/logging of rotary, RC and core drilling. He has remained active brokering and evaluating mineral properties in western U.S. and managing crews for all phases of mineral exploration.

He has a strong personal interest in gold-silver exploration and small, high-grade mine development. As a private contractor, Nick has owned and operated a Simco 4000 track mount drill and, authored/co-authored NI 43-101 compliant reports. Early work experience included three years of Federal Agency geotechnical investigation work, including extensive slope stability studies.

Mr. Barr holds a Bachelor of Science degree in Geology from Southern Oregon State University, Ashland, Oregon.
