Other/historical names associated with this locality:
Stephenson-Bennett Mine; Empire Zinc Mine


A Pb-Ag mine located NE of Las Cruces. Opened in 1849 and reopened in 1887.


Structure:Torpedo-Bennett Fault Zone Strikes North-South.

Deposit: The three major orebodies are the Stephenson, the Bennett and the Page. The Bennett is the largest and has been mined down dip for about 600 ft, has a width of 500 ft along strike and averages 10 ft in thickness. Three patented claims and one unpatented claim.

Rock formation(s):Organ Batholith
Fusselman Dolomite; Montoya Group


Ore(s):Mineralized solutions rose along fault zones and replaced favorable host rocks.



The locality was closed to underground collected following the death of a teenager from a fall down a shaft in the mine in 1991 (Albuquerque Journal 1991).
