Recent PRGCI Mining Project Case Histories

Management of Alaskan Field Operations for North Star Exploration, Inc. From 1999-2002, PRGCI managed programs and the Alaskan field office of the Denver-Based junior company North Star Exploration, Inc. (NSEI), which leased 7 million acres of interior Alaska lands owned by Doyon Limited, a native regional corporation based in Fairbanks. The work plan carried out programs ranging in size from $1.5 to $3.2 million USD in exploration using up to 15 geologists, logistical personnel and geophysics experts annually. First-phase drill programs were carried out on five properties. Exploration Confidentiality agreements were signed with 13 companies.

Projects under PRGCI management resulted in the discovery of PGE-Ni prospects near Farewell, a high grade silver-gold-copper prospects near Northway Junction, a copper-gold prospect at Divide in the Goodpaster district, a high sulfidation gold-silver prospect at Kaiyah on the Yukon River, and promising gold prospects in the Innoko district near McGrath.
