The Midway 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.

Comments

Comment (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = The Midway prospect was found by WGM Inc. and Patino Ltd. during exploration for base metals in the late 1970s on lands selected by Doyon Ltd. A soil grid established a 500 feet by 800 feet (152m by 244 m) anomalous zone which averages 250 ppm zinc and 100 ppm lead. Nearby stream sediment sampling yielded up to 176 ppm lead and 500 ppm zinc (Andrews and Rishel, 1982).

Comment (Deposit): Other Comments = the Midway prospect is on land selected or coveyed to Doyon Ltd. For further information, contact Doyon Ltd. at 210 1st Ave., Fairbanks, Alaska, 99701.

Comment (Geology): Geologic Description = The Midway smithsonite prospect is located along a break in slope in limestone and dolomite of the Telsitna Formation of Dutro and Patton (1982). The Midway occurrence is mainly manifested in anomalous lead and zinc in springs and seeps that occur along a break in slope. Smithsonite was identified in solution breccias exposed in rubble. Most of the prospect area is covered by vegetation. A soil grid established a 500 feet by 800 feet (152m by 244 m) anomalous zone which averages 250 ppm zinc and 100 ppm lead. Nearby stream sediment sampling yielded up to 176 ppm lead and 500 ppm zinc (Andrews and Rishel, 1982).
