Theodore (Ted) DeMatties
CPG, PG., of Cambridge, Minnesota
Theodore (Ted) DeMatties, CPG, PG., of Cambridge, Minnesota, is a U.S.-based consulting geologist with experience in exploring the geology and mineral deposits of the Stillwater Range in Nevada. His recent work in the Stillwater Range has led to the better understanding of the potential for iron oxide-copper-gold (“IOCG”) deposits in the area. Mr. DeMatties is the author of a technical report for the Treasure Box-Boyer Mine area entitled “An Evaluation of the 2BAR Copper-Oxide Property, Churchill County, Nevada, U.S.A.” dated March 1, 2016.
During his 40-year career as a geologist, Mr. DeMatties has been responsible for planning, management, and execution of mineral exploration programs, and detailed mining and mineral property evaluations for numerous clients. Deposit-type experience includes volcanogenic and sediment-hosted massive sulfide deposits in Precambrian and younger terranes, shear zone and iron formation-hosted gold deposits, as well as copper-nickel-PGM deposits associated with mafic-ultramafic rocks. He acted as field manager for a major, long-term, multimillion-dollar joint-venture volcanogenic massive sulfide (VMS) exploration program in Wisconsin, which led to the discovery of the Bend copper-gold deposit.
In 2017, Mr. DeMatties published a paper in Ore Geology Reviews entitled: “The Jurassic – Tertiary unconformity: A new exploration target for supergene-enriched iron oxide copper-gold –style mineralization in the Humboldt mafic complex, Nevada, USA”, which specifically discusses the copper, nickel and cobalt deposits of the eastern Stillwater Range where Nevada Sunrise holds interests in exploration properties.
Dr. John Oldow
La Conner, Washington
Dr. John Oldow, of La Conner, Washington, is a geological technical advisor to the Company. Dr. Oldow has over 40 years of experience in the field of geology, and is currently Director of the Ellison Miles Center for Geological Field Studies at the University of Texas, Dallas. His work is largely field based and includes geologic mapping and the application of structural and stratigraphic analysis, potential-field geophysics, GPS geodesy and Terrestrial Laser Scanning to better understand regional tectonics. He attained a Bachelor of Science, Geology from the University of Washington in 1972 and his Ph.D. in Geology from Northwestern University in 1978. Among the many tributes he has received in his long academic and professional career, Dr. Oldow has served by invitation on numerous committees for the National Science Foundation, and is a Fellow of the Geological Society of America (1992).
The results of Dr. Oldow’s field work in western Nevada on regional tectonics in the Walker Lane trend, specifically in Esmeralda County, led to the application of his work by Nevada Sunrise in its lithium exploration. His co-authored 2015 paper on the results of detailed gravity surveys in the Lida Valley prompted the acquisition of the Gemini Project, staked by Nevada Sunrise over two, deep sub-basins.
Carson City, Nevada
Dan Zampirro, of Carson City, Nevada, is a technical advisor specializing in the field of lithium brines exploration. Mr. Zampirro is a Certified Professional Geologist with the American Institute of Professional Geologists and a California licensed Professional Geologist through the Association of State Boards of Geology. He is a graduate of the Mackay School of Mines, University of Nevada, and started his career in mineral exploration for Homestake Mining Company in 1984. In 1986, Mr. Zampirro began working at the Round Mountain Gold Mine in Nevada where he eventually acted in project management and supervision of well drilling, dewatering processes and interpretation of the local hydrogeology. In 2000, Dan joined Chemetall-Foote Corporation at its Silver Peak, Nevada lithium mine (now owned by Albemarle Corporation), where he was responsible for the lithium brine well-field system, selection of drill sites for well production, delineating the aquifers in the Clayton Valley, and supervision of exploration drilling to define the reserve potential of lithium-bearing brine. His 2003 paper, “Hydrogeology of Clayton Valley Brine Deposits, Esmeralda County, Nevada” is widely regarded as a landmark description of the Clayton Valley aquifer system and its lithium brine deposits.
