• Description:
  The Ketchikan to Hyder areas comprise the eastern part of the Ketchikan Mining District, which is located in southern Southeast Alaska. Work accomplished in 1992 constitutes the third year of the U.S. Bureau of Mines' five-year Ketchikan Mining District study. This report summarizes the U.S. Bureau of Mines' work completed between May and September, 1992. Three two-person crews investigated 195 mineral localities and collected 1,689 samples from Federal, State, and private lands. Efforts were concentrated on the Helm Bay and Hyder areas because of their historic mineral potential. Past production of gold from the Goldstream, Gold Banner and Goo Goo Mines and production of zinc and lead from the Mahoney Mine prompts individual discussion of these locations. Results of sample analyses indicate the potential for a large tonnage, low grade gold deposit in the Helm Bay area. Numerous polymetallic-gold quartz veins in the Hyder area indicate widespread mineralization, possibly akin to the nearby gold-silver producing ore bodies in Canada. However, no specific ore bodies have been delineated to date.
