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 (Location): AT TERMINUS OF SULTAN BASIN ROAD

Comment (Workings): LARGE SURFACE CUT, ADITS, DRIFTS, RAISES, STOPES

Comment (Geology): MELANGE IS PART OF A SERIES OF ACCRETED TERRANES

Comment (Deposit): NATURE OF DEPOSIT IS UNCLEAR FROM DESCRIPTIONS. IT APPEARS AS IF IT MAY REPRESENT TWO DISTINCT EPISODES OF MINERALIZATION, THE FIRST A MAGMATIC SEGREGATION AND THE SECOND A HYDROTHERMAL OVERPRINT. THERE ARE 4 MAIN VEIN SYSTEMS AND LENSES OF CHROMITE TO 4 X 5 FT. ATTITUDE IS OF ONE MINERALIZED SHEAR ZONE
