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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Reserve-Resource): MATRIX 1 COLUMN 1 CONTAINS THE INDICATED AND INFERRED TONNAGES FROM THE CAROL J MINE MATRIX 2 COLUMN 1 CONTAINS THE INDICATED TONNAGE FOR THE HOPE MINE. MATRIX 2 COLUMN 2 CONTAINS THE INFERRED TONNAGE FOR THE HOPE MINE, BUT NOT THE INDICATED TONNAGE.
Comment (Reserve-Resource): ABOUT 19,000 TONNES OF INDICATED AND 9000 TONNES OF INFERRED SUBECONOMIC RESOURCES WITH AN AVERAGE GRADE OF 2.4 G/T GOLD AND 123 G/T SILVER ARE IN THE MAIN QUARTZ VEIN. THIS VEIN WITH AN AVERAGE THICKNESS OF 0.9 METERS IS SPORADICALLY EXPOSED ON THE SURFACE FOR 91 METERS AND WAS PRESUMED TO EXTEND AN ADDITIONAL 91 METERS ALONG STRIKE AND 45 METERS DOWNDIP. ONE INFERRED BLOCK IS 91 METERS ALONG STRIKE AND 45 METERS DOWNDIP BELOW THE INDICATED BLOCK. AN ADDITIONAL 2100 TONNES OF INDICATED AND 1000 TONNES OF INFERRED SUBECONOMIC RESOURCES OF 30 G/T SILVER IS IN THE SHEAR ZONE EXPOSED IN THE ADIT. ITS EXPOSED STRIKE LENGTH IS 40 METERS AND THICKNESS IS 0.5 METER. THE ZONE WAS PROJECTED DOWNDIP AND UPDIP FOR ONE-HALF OF THE STRIKE LENGTH. THE INFERRED BLOCK WAS CALCULATED BY EXTENDING THE INDICATED BLOCK 20 METERS ALONG STRIKE. ABOUT 76,000 TONNES OF SUBECONOMIC RESOURCES OF SILVER, ZINC AND LEAD ARE ESTIMATED IN A ZONE OF FISSURE VEINS THAT STRIKE NORTHEAST AND DIP 45 DEG. NW FROM LEVEL 2 TO THE SURFACE. THE ZONE IS EXPOSED FOR 23 METERS ALONG STRIKE, 21 METERS DOWNDIP AND IS 11 METERS THICK. FROM THIS BLOCK, 9,000 TONNES WAS SUBTRACTED FOR PREVIOUSLY MINED ORE, GIVING A 13,000 TONNES OF INDICATED SUBECONOMIC RESOURCES OF 140 G/T SILVER, 4.4 PERCENT ZINC, AND 2.1 PERCENT LEAD. BY EXTENDING THE VEIN DOWNDIP 30 METERS TO LEVEL, 38,000 TONNES OF INDICATED SUBECONOMIC RESOURCES WITH AN AVERAGE GRADE OF 110 G/T SILVER, 3.5 PERCENT ZINC, AND 1.6 PERCENT LEAD WOULD BE IN A TRAPEZOID 20 METERS ACROSS THE BASE AND 11 METERS ACROSS THE TOP. EXTENDING THE VEIN DOWNDIP ONE-HALF ITS 58-METER DIP LENGTH, MAINTAINING THE 20-METER THICKNESS AND 23-METER STRIKE LENGTH, AN ADDITIONAL 35,000 TONNES OF INFERRED RESOURCES CONTAIN AN AVERAGE 6.9 G/T SILVER, 0.38 PERCENT ZINC, AND 0.07 PERCENT LEAD.
