Work began in 1995 on Admiralty Island, then progressed south with an airborne magnetic and ElectroMagnetic (EM) survey (flown in 1996) to the Duncan-Zarembo area, and is now focused on following up a 1999 airborne mag/EM survey on Prince of Wales Island.
The driving forces behind all this work are the forced cutbacks in logging permits, and the search for a new Greens Creek-type deposit as a local economic alternative to logging.
Areas with potential for volcanogenic massive sulfide (VMS) deposits are the targets of the airborne geophysics.
