The Waterfall Creek is a zinc mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Alterations
Alteration Type: L
Alteration Text: Alteration at the Waterfall Creek prospect consists of chloritization of the basalt, iron oxide in breccia clasts in silicified limestone or quartzite, and quartz veins and vug fillings (DiMarchi and others, 1993).

Comments
Comment (Exploration): Status = Active
Comment (Deposit): Model Name = Fault-controlled Zn?
Comment (Deposit): Other Comments = This prospect is located on Doyon, Limited selected or conveyed land. For more information, contact Doyon, Limited. This site is within the Yukon-Charley Rivers National Preserve.
Comment (Geology): Geologic Description = The Waterfall Creek prospect is underlain by northwest-dipping, Upper Proterozoic to Lower Cambrian Tindir Group rocks (redbeds, basalt, limestone, and conglomerate), which transition northwestward into black chert, green siltstone, and quartzite (DiMarchi and others, 1993). The Waterfall Creek thrust separates the Tindir Group from a Cambrian through Permian sedimentary sequence which lies to the west. Bedding in this area generally strikes north-northeast and dips from 80SE to 55NW (DiMarchi and others, 1993). Minor fine-grained disseminated pyrite is present in altered basalt and siltstone units. Alteration consists mostly of chloritization of basalt and oxidation of cherts and siltstones. Iron oxides are found locally, most of them in clasts of breccia which is hosted by silicified limestone or quartzite. White quartz veins and drusy quartz veinlets and vuggy fillings are also common in brecciated rocks (DiMarchi and others, 1993). Soil and stream sediment samples taken by WGM Inc. and by ASA Inc. are anomalous in zinc in the prospect area. Weak anomalies of molybdenum and lead were also found (DiMarchi and others, 1993).
Comment (Geology): Age = Permian or younger.
Comment (Reference): Primary Reference = DiMarchi and others, 1993
Comment (Workings): Workings / Exploration = WGM Inc. conducted a soil and rock sampling program on the property in the mid-1970s, and in 1993 ASA Inc. conducted a soil and rock sampling program and geologic mapping. The property is located on Doyon, Limited selected or conveyed land.
