Comments
Comment (Workings): Workings / Exploration = A 3,000 foot (915 m)-long soil anomaly contains up to 1.05 percent zinc and 450 ppm lead (Andrews and Rishel, 1982).
Comment (Geology): Age = the host rock is inferred to be Silurian based on fossil control (Dutro and Patton, 1982). The age of the mineralization is unknown.
Comment (Reference): Primary Reference = Andrews and Rishel, 1982
Comment (Commodity): Gangue = Carbonate solution breccia
Comment (Deposit): Other Comments = See Reef Ridge deposit (MD055), and Cache Creek South (MD038) Prospect. The Cache Creek - North occurrence is on lands selected or owned by Doyon Ltd. For further infomation, contact Doyon Ltd at 210 1st Ave., Fairbanks, Alaska, 99701.
Comment (Geology): Geologic Description = Mineralization only occurs as rubble-crop of the Silurian Paradise Fork Formation of Dutro and Patton (1982), which is also unit 'Sic' of Andrews and Rishel (1982). Cache Creek North is northern end of North 55 degrees East striking unit of micritic limestone and white dolomite. The host rock is inferred to be Silurian based on fossil control (Dutro and Patton, 1982). A 3,000 foot (915 m)-long soil anomaly contains up to 1.05 percent zinc and 450 ppm lead (Andrews and Rishel, 1982).
Comment (Deposit): Model Name = Southeast Missouri Pb-Zn (Cox and Singer, 1986; model no. 32a) or Mississippi Valley Type
Comment (Exploration): Status = Inactive
