TOPIC: "Ruby Creek Copper Deposit, Alaska" Ruby Creek is a copper deposit within a dolomitic sequence which has Mississippi Valley type affinities. It occurs within the Ambler District of Northern Alaska, where other known deposits are volcanogenic in character. Recent work by Hitzman suggests a hitherto unrecognised alteration and mineral zoning which has particular significance for further exploration.
