Land Status

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Workings): Current mining operations are primarily dump leaching activities, with recovery of copper from leach solutions using conventional solvent extraction-electrowinning (SX-EW) technology.

Comment (Ownership): Mines Id Also Listed As 200142 When Owned/Operated By Duval.

Comment (General): Lang et al, 1989 describe the Wallapai mining district as 6 by 20 km, the extent of large brecciated, polymetallic quartz sulfide veins. Host rocks for the porphyry copper-moly deposit are Precambrian felsic and mafic rocks, and the Laramide Ithaca Peak stocks. Lang and Eastoe, 1988 describe polymetalic quartz veins around the Mineral Park porphyry that produced gold, silver, lead, zinc, and copper from 1863 through 1940's, the most significant of which were the Tennessee-Schuylkill and Golconda mines.

Comment (Production): Other Name:Ithica Peak.Temporary Shutdown 12/14/1981. Reference "The Primary Copper Industry Of Arizona", 1984 Special Report No. 9 , Arizona Department Of Mines And Mineral Resources. Cyprus Minerals And Amax Merged In Nov 1993. Leach Circuit Converted To A Sx-Ew In 1994. Production Data And Reserves From Mining Business Digest, May 1994, P. 5 & 6. Cu Production Only From Leach Dumps. Mine & Mill Shutdown.

Reference "The Primary Copper Industry Of Arizona", 1984 Special Report No. 9 , Arizona Department Of Mines And Mineral Resources. Cyprus Minerals And Amax Merged In Nov 1993. Leach Circuit Converted To A Sx-Ew In 1994. Production Data And Reserves From Mining Business Digest, May 1994, P. 5 & 6.

Comment (Ownership): Mineral Park Purchased By Cyprus Minerals For An Undisclosed Amount On Mar 31, 1986, From Duval Corp-Pennzoil United Inc. Cyprus Minerals Merged With Amax Inc. In November 1993

Comment (Reserve-Resource): The Tonnage In Matrix 1 Includes Sulfide And Oxide Ore Oxide Ore Is Assumed To Last Through The Life Of The Property. Tonnage From Titley, 1982, P 523 Less 2 Yrs Production. M2c1=R2. 1986 (Jan 1, 1986) Reserve Given In Az Dept Of Mines & Min Res Special Report No 10, 1985, P. 20.

Comment (Geology): Turquoise Is Mined From The Pit Under Lease.
