The Lisburne Ridge is a phosphorus-phosphates 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.

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 = Sample contained 24.8% P2O5 and 0.17% V2O5 (Patton and Matzko, 1959, p. 11).
Comment (Reference): Primary Reference = Patton and Matzko (1959)
Comment (Geology): Geologic Description = Sample from an 8 ft. zone of rubble of black chert, black paper shale, black shaly dolomite, and oolitic phosphate rocks in the Carboniferous Lisburne Group; there probably are 2 horizons (each about 6 in. thick) of phosphate rock (Patton and Matzko, 1959, p. 11-12). Stratigraphic position in Lisburne Group uncertain.
Comment (Deposit): Model Name = Lode; phosphorite
Comment (Deposit): Other Comments = See MAS/MILS Sequence # 0020200004 (USBM, 1995)
Comment (Commodity): Ore Material = Phosphorite
Comment (Geology): Age = Carboniferous
