Sidorov Introduced to Alaska Mining Community by AMA

Tom Bundtzen, Donald Grybeck, and Warren Nokleberg. The group examined several platinum-bearing Ural- Alaska type, zoned mafic ultramafic igneous complexes. AMA invited Sidorov and 11 other Soviet scientists to attend and present papers at the 1990 Annual Convention in Anchorage, which hosted the symposium “The Geology and Metallogeny of the Soviet Far East, Alaska, and Canada”. Papers generated by Russian colleagues were later published in a Special Symposium Volume released by the AMA in 1995. In 1996, Sidorov and members of the Koryak Geology Mining Company (KGD), which mined placer platinum in Kamchatka at a large scale, were invited by Alaskan geologists and the Calista Native Corporation, which included Jeff Foley, June McAtee, Tom Bundtzen, and Toni Hinderman, to tour the Goodnews Bay platinum district and several other platinum-bearing districts in Alaska and Yukon Territory. The newly recognized platinum district in Kamchatka exhibits remarkable geomorphological similarities to Alaska’s Goodnews Bay district. In 1997, Sidorov helped organize a reciprocal visit for Calista Corporation to inspect the platinum mining activities in the Galmeonan district of Kamchatka.

During 2000 and 2001, Sidorov again returned to Alaska to prospect for platinum as consultant for Denver- based North Star Exploration, Inc (NSEI). Later in 2001, Eugene organized a grassroots examination for NSEI of newly discovered PGE-Ni-Co-Cu deposits related to Tertiary mafic-ultramafic intrusions in southwest Kamchatka. Samples of mineralization were collected and subsequently dated at the University of Alaska geochronology laboratory in Fairbanks. One of the PGE-Ni-Co-Cu deposits, Shanuch, has since become a producing mine. In 2005, Sidorov and Larissa Karpova helped organize an AMA trip to Kamchatka where platinum and gold mining projects, geothermal power developments, and other resource industries were viewed. Of note was a demonstration by KGD of the successful use of acoustical technology to remove clay-sized particles in mine process water, which holds promise for mitigating water quality issues elsewhere. It should be noted that in 2006, the Kamchatka Miners Association was formed, in part recognizing AMA as a highly successful organization that effectively represented regional mining interests in Alaska.

BO NU IEL DO IUNNGC AE LAATS AK AT I M E CONAM’s track record of succesful projects has proven that resource development can be done responsibly while protecting Alaska’s fragile environment. Our firm understanding of Alaska’s unique challenges and commitment to HSSE and planning have translated into satisfied mining clients across the state. We get dirty so you get the pay dirt.
