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 (Geology): LATERITE SHOULD BE A MINERAL ENTRY; IT IS PROCESSED FOR COMMODITY CONTENT. SAPROLITE SHOULD BE A MINERAL ENTRY; IT IS PROCESSED FOR COMMODITY CONTENT. MAGHEMITE IS NOT IN MINERAL TABLE. RECENT RESEARCH INDICATES MOST OF THE NICKEL (AND PRESUMABLY THE COBALT) IS INCLUDED IN THE GOETHITE LATTICE. NICKEL AND COBALT ARE RELEASED FROM THE PARENT MINERALS AND RECOMBINED IN THE IRON OXIDES. OLIVINE IS THE PROBABLE SOURCE OF NICKEL. SOURCE OF COBALT IS UNKNOWN.

Comment (Ownership): CALIFORNIA NICKEL CORP. IS A SUBSIDIARY OF NI-CAL DEVELOPMENTS LTD. (A CANADIAN FIRM).

Comment (Geology): THE SHAPE OF THE LATERITE AREAS IS GENERALLY TABULAR, BOTTON IS HIGHLY IRREGULAR.

Comment (Production): PROPERTY HAS NOT PRODUCED (1979).

Comment (Reserve-Resource): FIELD OP. FIRST QUARTER F.Y.1980 INCLUDES THIS IN ILLINOIS VALLE NICKEL LATERITE DEPOSITS, /EXTENSIVE DATA BASE REVISION AND REVI MINE COSTING DUE. OWNERS: CALIFORNIA NICKEL CORP., HANNA MINING CO., MERIDIAN RESOURCES LTD., AND PAN ARCTIC. OTHER NAMES: EIGHT DOLLAR NICKEL DEPOSIT, EIGHT DOLLAR MTN GROUP, AND HORSTMAN GROUP. NOTHING IN RANDOL 93-94.

Comment (Deposit): LOCATION IS POINT OF ENTRY TO PROPERTY AT TURNOFF FROM EIGHT DOLLAR ROAD. NICKEL AND COBALT ARE ENTERED AS COPRODUCTS RECOVERY OF COBALT AND NICKEL IS NECESSARY FOR PRODUCTION AT CURRENT PRICES, (1979).

Comment (Reserve-Resource): QUANTITY ESTIMATES TAKEN FROM B-BIB Q800-Q805 ASSAY FE- 1977

Comment (Geology): UNSPEC SEDIMENTARY FOR LACK OF AN APPROPRIATE ENTRY FOR LATERITE. LATERITIC SOIL COMPOSED OF HYDROUS FE-OXIDES, CLAY MINERALS, AND POSSIBLE GARNIERITE WITH RESIDUAL SILICA AND CHROMITE. SAPROLITE, THE CLAY-RICH WEATHERED HOST ROCK, IS A SIGNIFICANT, BUT VARIABLE, PERCENTAGE OF THE RESOURCE.
