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): THIS ESTIMATION IS BASED ON THICKNESS MEASURED ON OUTCROPS, PROSPECT PITS, AND DRILL HOLE DATA, AND THE TONNAGE IS COMPUTED ON THE BASIS OF A MINIMUM THICKNESS OF 0.8 M, SPECIFIC GRAVITY OF 1.25 AND 1.25 MET TONS/CUBIC METER.

Comment (Location): LONGITUDE AND LATITUDE ARE FOR THE CENTER OF THE QUADRANGLE. MAXIMUM ALTITUDE LISTED

Comment (Reserve-Resource): SEE RESERVES AND POTENTIAL RESOURCES COMMENTS

Comment (Development): ECON.COM: THE CHARACTER OF THE OVERBURDEN IMPOSES NO STRIPPING PROBLEM ABOVE THE SHADEHILL FACIES. IF THE HILLEN BED IS EXPLOITED, THE SCOTCH CAP SANDSTONE WOULD PRESENT A MINING PROBLEM AS IT IS MODERATELY THICK AND EXCEPTIONALLY HARD IN PLACES. THERE IS A POTENTIAL STRIPPING AREA IN SECS. 8, 9, 16, 17, T. 18 N., R. 12 E.
