The U.S. Bureau of Mines is currently conducting a 4-yr study to assess the mineral resources and the mineral development potential of the 5.7-million-acre Valdez Creek Mining District (VCMD) in south- central Alaska. The VCMD study is part of the Bureau's ongoing statewide mining district evaluation program. This report is a summary of the 1988 fieldwork, which involved collection of reconnaissance placer and rock samples and also sampling and examination of the mines, prospects, and mineral occurrences that were identified by literature research of the geology, exploration history, and mining history of the district. During the 1988 field season, Bureau personnel spent 11 weeks in the field, collected 1,006 rock and placer samples, and located, mapped, and sampled 106 of the known mineral occurrences. The Bureau visited 243 of the 250 known mineral occurrences during the project. Reconnaissance sampling for placer occurrences resulted in the identification of four previously unreported gold placer occurrences and five occurrences that contain detectable levels of platinum or palladium. Reconnaissance sampling for lode sources of base and precious metals resulted in the identification of five new lode gold-silver occurrences, two occurrences that contain elevated quantities of chromium, cobalt, nickel, palladium, and platinum, and one occurrence that contains elevated quantities of copper, molybdenum, and zinc.
