A former medium output underground Cu-Pb-Zn-Au-Ag mine located in the North-central sec. 16, T.23S., R.24E. (Bisbee 7.5 minute topo map), approximately 1 mile W of Lowell, on private land. One of the early mines of the district. The Spray shaft is one of the main shafts of the Copper Queen. Owned by the Phelps Dodge Corp.

Mineralization is mostly oxidized copper with minor lead-zinc ores in both metamorphosed and relatively unaltered Cambrian Abrigo Limestone. Ore control was nearby dikes and sills, and faulting and associated brecciation. Ore concentration was bornite replacing pyrite. Alteration was gossan with Mn and Fe oxides induced by hydrothermal metamorphism. An associated rock unit is the Sacramento Hill Stock.

Local structures include common pre-mineralization faulting and tilting. Main fault directions are N10W to N40E and S30W to N50W.

Workings include a shaft(s) to a depth of 243.84 meters. The shaft has eight levels and is connected to the other main shafts of the Copper Queen Mine. The second, third, and fourth levels are the same as the corresponding Holbrook shaft levels. This is one of the early mines of the district with a production of several hundred thousand tons.
