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.

Comment (Commodity): Ore Materials: gold

Comment (Commodity): Gangue Materials: quartz

Comment (Deposit): Most ore mined at Illipah was from teh upper 50 feet of the Devils Gate Limestone.

Comment (Economic Factors): The orebody was defined by drilling in 1985 and geologic reserves stood at 1.9 million tons of ore grading 0.048 opt gold. Reserves of 57,000 ounces of gold were reported in 1987. Production from the Illipah Mine from 1987 through 1989 was 54,198 ounces of gold, including gold recovered from the heap leach after miing ceased.

Comment (Identification): This record includes data from from MRDS record M242967, which has been deleted. This record is an updated version that incorporates all information in earlier MRDS record W700448 for the Illipah Mine plus additional updated material.

Comment (Location): The Illipah Mine was an open pit heap leaching operation consisting of approx. 514 unpatented mining claims covering approx. 9770 acres of federally-administered land.

Comment (Workings): Illipah was developed by three small open pits.

Comment (Development): Tenneco acquired the Illipah property from Earth Resources in 1980 and in 1981 intersected the southern end of the Illipah orebody. Tenneco drilled nearly 400 holes during the period 1980-1986. The property was included in the purchase of Tenneco's mineral holdings by Echo Bay Mines Ltd. On June 1, 1988, Echo Bay entered into the Alta Bay Venture with Alta Gold Co. Alta Gold gained a 60% interest in the venture and became operator of the Illipah Mine. Production commenced in October, 1987. The Illipah mine employed a total of about 60 workers in 1987. Gold recovery was estimated at 90% using heap leach technology. Gold-bearing solutions from the heap leach were treated in carbon adsorption tanks. The loaded carbon was sent to the McCoy mine plant for recovery of contained gold. Reserves at the Illipah mine had been mined out by the end of 1988, but heap- leaching continued through the summer of 1989 and the mine closed late in the year.
