Dennis Ladue

The Dennis Ladue is a gold 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.

Comments

Comment (Deposit): Model Name = Epithermal Au/Ag/W, distal to porphyry? (Doyon Ltd., 1998)

Comment (Deposit): Other Comments = This property lies within Doyon Ltd. selected lands. For more information, contact Doyon Ltd.

Comment (Geology): Geologic Description = The Dennis Ladue prospect is underlain by granite, syenite, aplite and porphyritic rhyolite phases of a composite felsic stock. This stock intrudes chlorite schists, biotite schists, and quartzite. The alteration at the property is structurally controlled, and shows evidence of intense silicification within the granite and the rhyolite (DiMarchi and others, 1989). Quartz veins and vein breccia follow north-trending shoots; the veins have traces of pyrite and tourmaline (DiMarchi and others, 1989). The prospect lies within the eastern portion of the Y1 subterrane of the Yukon-Tanana terrane (Foster and others, 1994). In 1995, a re-analysis of WGM Inc. soil and silt samples by Doyon Ltd. revealed anomalous values of tungsten, silver, gold, antimony, arsenic, barium, molybdenum, and zinc.

Comment (Reference): Primary Reference = Doyon Ltd., 1998

Comment (Workings): Workings / Exploration = In 1975, WGM Inc. conducted a stream silt reconnaissance program on the property, and in 1981 Arctic Resources Inc. analyzed ridgeline soils. In 1985, Doyon Ltd. reanalyzed the silt and soils that contained greater than 20 ppb gold. In 1989 Central Alaska Exploration Corp. did mapping as well as rock, soil, and stream sediment sampling. In 1991, Central Alaska Gold Company conducted rock and soil sampling for gold mineralization.

Comment (Exploration): Status = Active
