The Ibex Saddle is a silver, lead, and zinc mine located in Alaska.
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.
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 (Workings): SAMPLES OF THE DEPOSIT COLLECTED BY THE U.S. BUREAU OF MINES IN 1992 OR 1993 (MAAS AND OTHERS, 1995, P. 245) CONTAIN UP TO 656 PPB AU, 40.7 PPM AG, 2705 PPM CU, 2.6% PB, AND 7.5% ZN.
Comment (Geology): LEAD-ISOTOPE STUDIES OF GALENA FROM THE IBEX SADDLE PROSPECT (MAAS AND OTHERS, 1995, P. 235) INDICATE THAT THE DEPOSIT IS JURASSIC IN AGE, CONTEMPORANEOUS, AT LEAST IN PART, WITH ISLAND-ARC VOLCANISM IN HAZELTON TIME (ALLDRICK, 1993).
Comment (Location): THE IBEX SADDLE PROSPECT (MAAS, 1995, P. 233, 235, 245) IS IN THE SOUTH PART OF SECTION 1 AT AN ELEVATION OF ABOUT 4500 FEET, ADJACENT TO THE WEST MARGIN OF A SMALL LOBE OF TEXAS GLACIER AT THE HEAD OF IBEX CREEK. THE LOCATION IS ACCURATE WITHIN ABOUT 0.1 MILE.
Comment (Deposit): THE COUNTRY ROCKS IN THE AREA OF THE IBEX SADDLE PROSPECT ARE PELITIC METASEDIMENTARY AND SUBORDINATE ANDESITIC VOLCANIC STRATA OF THE JURASSIC OR OLDER MESOZOIC HAZELTON GROUP, WHICH IS UNDERLAIN AND LOCALLY INTRUDED BY THE TRIASSIC TEXAS CREEK GRANODIORITE; AND THE EOCENE HYDER QUARTZ MONZONITE, WHICH INTRUDES THE HAZELTON AND TEXAS CREEK ROCKS (SMITH, 1997; KOCH, 1996). MAAS AND OTHERS (1995, P. 235, 245) DESCRIBE THE DEPOSIT AS SULFIDE-BEARING SILICIFIED[?] ANDESITE. THE SULFIDES ARE PYRITE, GALENA, AND SPHALERITE. SAMPLES OF THE DEPOSIT COLLECTED BY THE U.S. BUREAU OF MINES IN 1992 OR 1993 CONTAIN UP TO 656 PPB AU, 40.7 PPM AG, 2705 PPM CU, 2.6% PB, AND 7.5% ZN. LEAD-ISOTOPE STUDIES OF GALENA FROM THE IBEX SADDLE PROSPECT (MAAS AND OTHERS, 1995, P. 235) INDICATE THAT THE DEPOSIT IS JURASSIC IN AGE, CONTEMPORANEOUS, AT LEAST IN PART, WITH ISLAND-ARC VOLCANISM IN HAZELTON TIME (ALLDRICK, 1993).
