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 (Reserve-Resource): IT IS NOT SPECIFICALLY KNOWN IN WHAT FORM THE NICKEL AND COBALT OCCUR IN THE ORE, BUT RECENT RESEARCH INDICATES THAT THEY MAY BE A SIGNIFICANT PART OF THE GOETHITE LATTICIE. RESOURCE ESTIMATES DEVELOPED IN-HOUSE 1979.

Comment (Reserve-Resource): OTHER NAMES: RIDGE CLAIMS GTR NOS.1-18. THE LATTER NAME IS AN ALTERNATE ON 0060150116 (CAM LATERITE EXTENSION). IN NICKEL LATERITE INVESTIGATIONS IN NORTHERN DEL NORTE COUNTY, DEPOSIT REPORT BY RIDENOUR. METAL CONTENT: 0.40 WT.PCT.NI, 0.05 WT.PCT.CO, AND 2.1 WPT.PCT.CR. DR INCLUDES JUDY AJWNOS 1-5, FORMERLY MAS SEQ NO. 0060150249 LAT- N415545, LON-W1235834, RAW PROSPECT.

Comment (Production): THIS WORK WAS FUNDED THROUGH METALLURGY RESEARCH AS PART OF A PROGRAM TO DETERMINE THE BASIS FOR CONTINUED EXPENDITURES BY ALBANY METALLURGY RESEARCH CENTER ON THE REDUCTION ROAST- AMMONIACAL LEACH PROCESS CURRENTLY UNDERGOING PILOT PLANT TESTING. BACKHOE AND SEISMIC WORK WAS CONTRACTED WITH BASIC SAMPLING, MAPPING, AND INTEGRATION OF DATA PERFORMED BY U.S. BUREAU OF MINES WFOC PERSONNEL. THE WORK WAS ACCOMPLISHED FROM MAY TO AUGUST, 1978

Comment (Geology): ALTHOUGH THE AMOUNTS OF THE VARIOUS MINERALS ARE LISTED AS VARIABLE, RECENT RESEARCH INDICATES GOETHITE CONSTITUTES A SEGNIFICANT PERCENTAGE OF THETOTAL MINERALOGY.

Comment (Ownership): CAL NICKEL PURCHASED THESE CLAIMS FROM INTER-AMERICAN NICKEL COMPANY IN 1978
