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 (Production): RECOVERIES HAVE BEEN ROUNDED. RECOVERIES ARE ACTUALLY 71.8% FOR TIN, 94.5% FOR TANTALUM, AND 77.9% FOR NIOBIUM. NIOBIUM.
Comment (Economic Factors): THE ORIGIN POINT LATITUDE AND LONGITUDE IS THAT OF THE ETTA MINE ITSELF.
Comment (Reserve-Resource): THERE ARE 8 ADDITIONAL DUMPS THAT HAVE NOT BEEN EVALUATED BY THE PACER CORP. RESERVES OF TANTALUM, COLUMBIUM, AND TIN ARE LIKELY TO INCREASE AFTER EVALUATION OF THESE ADDITIONAL DUMPS. SEE APPENDIX B-2 OF REPORT. THE ABOVE RESERVE DATA WAS PROVIDED BY PACER CORP. (SEE APPENDIX B-2). ALTHOUGH THE FIGURE IS BASED ON MINIMAL EXPLORATION, AND CONSEQUENTLY IN A LOWER PROBABILITY CATEGORY, THE EVALUATOR BELIEVES MOST OF THE RESERVE WILL BE CONFIRMED.
Comment (Geology): ORE IS TO BE TAKEN FROM 8 DIFFERENT DUMPS AND FROM THE EXISTING HIGHWALL OF THE OLD ETTA MINE. CONSEQUENTLY, OREBODY DIMENSIONS CANNOT BE GIVEN. ALL ORE IN THE DUMPS IS FROM PREVIOUS MINING OF PEGMATITES.
Comment (Reserve-Resource): RESOURCES IN RECOVERABLE MT PROPOSED MINING WILL REWORK EXISTING DUMPS AND OPEN PIT MINE
Comment (Production): PRODUCT A IS THE TANTALUM-COLUMBIUM CONCENTRATE; PRODUCT B IS A TIN CONCENTRATE; AND, PRODUCT C IS GRAVEL WHICH IS THE TAILS FROM MILLING. PRODUCT C, GRAVEL, COMES FROM THE COARSE TAILS (SEE APPENDIX B-4 OF BACK-UP DATA).
