The Lucky Top 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): Other Comments = This vein is the probable source area for the placer gold and large nuggets in Lucky Gulch (HE207) below it.

Comment (Geology): Age = The vein cuts phyllite containing 64.1 Ma actinolitic hornblende.

Comment (Exploration): Status = Inactive

Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)

Comment (Workings): Workings / Exploration = There has been surface sampling and test pitting with occasional spectacular gold values. An adit was started in 1936 to test down-dip extension below outcrop.

Comment (Reference): Primary Reference = Smith, 1981

Comment (Geology): Geologic Description = The country rocks at the Lucky Top prospect is pelitic phyllite containing biotite porphyroblasts, and minor garnet and actinolitic hornblende. The hornblende at a nearby locality has been dated by K-Ar methods at 64.1 Ma (Smith, 1981).? the deposit consists of an auriferous, banded, comb-quartz vein in well-defined slate walls. It is accompanied by gouge and slickenslides and contains arsenopyrite and galena. Some small specimens of the quartz run very high in gold (Tuck, 1938). The placer on Lucky Gulch (HE207), located directly downslope from this prospect, is well known for its nuggets and coarse placer gold.
