A former summit. As of the early 2020s, this mountain has been destroyed by Freeport-McMoRan due to their expansion of mining in the area. A $60 million, 4-mile-long and 125-foot-wide haul road connects this mountain to their Chino Mine operations.

Structure: Barringer Fault. Deposit Localized Near Intersection Of Ne-Trending Fault Zones With N- And S-Trending Fractures.

Alteration: Granodiorite To Quartz Monzonite Dikes Extensively Altered To Sericite And Quartz. Sandstone And Hornfels Silicified.

Commodity: Supergene Minerals - Chalcocite. Primary Minerals - Cupriferous Pyrite Base Metal Sulfides Are Gold And Silver Bearing. Some Of The Older Mines That Are Now A Part Of The Pit Like The Continental And The Anson S Were Mined For Magnetite.

Deposit: Deposit Consists Of A Zone Of Supergene-Enriched Copper Minerals In The Cretaceous Colorado Formation In The Hanging Wall Of The Barringer Fault At The Extreme North End Of The Fierro-Hanover Stock And Is Associated With Complex Vein, Disseminated, And Replacement Mineralization. Deposit Consists Of A Leached Cap, 20 To 200 (Average 80) Ft Thick With 100 To >400 (Averaging 290) Ft Thick With 0.38% Acid Leachable Cu. Primary Mineralization Below Chalcocite Blanket Contains 4 To 7 Vol. % Pyrite And 0.2 To 0.5 Wt % Cu. Replacement Of Pennsylvanian Magdalena Group Limestone In The Footwall Of The Ne-Trending Barringer Fault Along The Northwest Side Of Fierro-Hanover Stock. Also Includes Vein And Supergene Deposits In Cretaceous Colorado Formation In Hanging Wall Of Fault Zone. This Record Contains Data From Record D011690 By Ron Worl Which Has Been Deleted From Mrds. ; Info.Src : 1 Pub Lit; 2 Unpub Rept Nine Patented Claims Mineral Survey Number 936 Covering 169.53 Acres.

Deposit type: Porphyry Cu

Development: Old Hanover Mine Opened 1841 By Hinckel For A Mexican Concern. Ore Smelted In An Adobe Furnace Destroyed Within A Year By Apaches. First Recorded Production Came From High Grade Vein And Replacement Deposits Between 1858 And 1910 From Hanover Shaft And Other Small Workings. Drilled 1993-1994 By Cobre Mining Co. Delineating Present Reserves. Supergene Enriched Ores Recognized As Early As 1899 When Explored By Copper Queen Consol. Mining Co. (Phelps Dodge). Mined For Iron From Extensive Underground Workings Prior To 1931. Between 1954 And 1968 Considerable Copper Ore Mined From Continental Mine And Leaching Operations In Zuniga Mine. In 1968 Open-Pit Mining Started.

Geology: Associated Rocks: andesite dike, basalt dike, breccia, gabbro, granodiorite porphyry, quartz diorite porphyry, quartz monzonite porphyry, skarn, syenodiorite porphyry;n.d.;andesite breccia, conglomerate, dolomite, felsic volcanic rocks, granodiorite, hornfels, limestone, marble, quartz monzonite, quartzite, sandstone, shale, siltstone, skarn Zinc Ore Bodies Are Replacement-Type In The Pyrometasomatic Zones. The Ore And Gangue Minerals Have Completely Replaced The Limestones (Lower Blue Limestone - A Member Of The Lake Valley Limestone And Oswaldo (Middle Blue) A Member Of The Pennsylvanian Magdelena Group). All Of The Remaining Ore Is In The Lake Valley Limestone. The Ore Is Adjacent To The Granodiorite Dikes And Seems To Con- Centrate Immediately Beneath The Parting Shale. The Dimensions Given Are For The Individual Ore Bodies (Or Pods) And Their Average Size.
