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 (Deposit): A LARGE DIKELIKE VEIN OF JASPEROID OCCUPIES THE EAST CAMP FAULT ZONE, WHICH STRIKES N 60 W AND DIPS NEAR VERTICAL. FLUORSPAR VEINS PARALLEL THE OUTSIDE WALLS AND ALSO WIND THROUGH THE JASPEROID. FLUORSPAR CROPS OUT IRREGULARLY IN A PERSISTENT VEIN PARALLEL TO THE JASPEROID DIKE FOR A DISTANCE OF 2500 FT. THE WIDTH OF THE VEIN RANGES FROM 12 TO 15 FT. THE VEIN MATERIAL IS COMPOSED OF FINE TO MEDIUM GRAINED QUARTZ, JASPEROID BRECCIA, FINE-GRAINED TO COARSE-GRAINED FLUORITE, AND MINOR AMOUNTS OF ARGENTITE, GOLD, HEMATITE, LIMONITE, AND MN-OXIDES. THE FLUORITE IS CLEAR, WHITE AND GREEN, AND HAS SOME HEMATITE STAINING.
Comment (Workings): WORKINGS INCLUDE A 50 FT VERTICAL SHAFT AND SEVERAL TEST PITS ALONG THE VEIN.
