A former Cu-Au-Ag-Zn mine located 6.9 km (4.3 miles) SE of Moonlight Peak.

Mineralization is a fissure Cu-Au-Ag-Zn deposit. The ore body strikes N60E and dips very steep N at a width of 36.58 meters. Controls for ore emplacement were shear zones in andesite porphyry and diorite. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).

Local structures include a fault plane striking N30W, and dipping 60SW, with a vertical throw. The section S of the fault is oxidized.

The Engel Mine area is a part of the Diamond Mountain block, with a width of 20 miles, and a length of over 50 miles. The block has a NW-SE trend and is bounded by a prominent escarpment on the E side. The principal rocks are plutonic, varying from gabbro-diorites to true granites with associated dike rocks. Older plutonic rocks, gabbro, diorite and quartz. The diorites are part of a large batholith of which the western border appears in the Engel Mine area. Other plutonic rocks occur as two stocks. One is predominently of quartz monzonite, while the other is a true granite. Older rocks are more basic, younger rock more acidic. Two types of pre-plutonic rocks are present. The older type is predominently rhyolitic, forming a series of tuffs, the younger type is an intrusive andesite porphyry. The ages of the plutonic rocks are suggested to be late Jurassic. The rhyolite and andesite porphyry are suggested to be Carboniferous.
Comments on the workings information

Workings include underground openings. These workings achieved a vertical depth of over 1,300 feet with 10 levels. There were a numerous amount of workings at the end of 1916. 14,000 feet of development work had been done. In 1927, the following development was done: 8,161 feet of drifts, 4,667 feet of raises, a 78 foot deep shaft and 19,980 feet of diamond drilling.

Production in 1918 was about 9,100,000 pounds of Cu.

Reserves and resources in 1927 were estimated at 352,000 metric tons of ore. Cu at 2.000000 wt-pct (1927).
