Origin

The Origin 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 site is located on land patented by, or interim-conveyed to, the Aleut Corporation.

Comment (Geology): Geologic Description = The Origin prospect consists of a knob of silicified and propylitized andesite on the trace of the Aquila linear (Peterson and others, 1982, figure 11). The andesite, which contains as much as 5 percent disseminated pyrite, is part of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). Trenches exposed a 70-foot-wide quartz-clay vein comprising 80 percent quartz and 20 percent clay. No trench sample of the vein contained more than 0.138 ppm gold, and most contained no detectable gold. Combined copper, lead, and zinc values ranged from 80 to 100 ppm. The samples contained as much as 500 ppm arsenic and 0.45 ppm mercury. One drill hole intersected a 25-foot zone averaging 0.171 ppm gold.

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Peterson and others, 1982

Comment (Workings): Workings / Exploration = During the period 1979 to 1982 Resource Associates of Alaska and UNC Teton Exploration Drilling Company mapped and sampled the prospect, drilled one 577-foot core hole, and cut four trenches for a total of 805 feet (Peterson and others, 1982). The 145 trench samples were essentially barren of base and precious metals. The drill hole intersected a 25-foot zone averaging 0.171 ppm gold.

Comment (Geology): Age = Eocene or younger.
