A former underground Au-Pb-Cu-Ag-Zn mine located in the W½NE¼ sec. 22, T4S, R29E, On the ridge between Chase Creek and Morenci Canyon, about 1 mile ESE of Morenci, on private land. The easternmost adit is located in the NE¼ sec. 22. Discovered 1875.
Mineralization is a vein that strikes NE-ward and follows a porphyry dike in Ordovician limestone, forms an outcrop of cellular quartz stained yellow by lead oxide. The ore body is tabular and is hosted in the Longfellow Limestone. Associated rock units are the Coronado Quartzite and the Morenci Granite Porphyry. Ore control was a NE-trending fissure vein following a porphyry dike that separates the Coronado Qartzite from the limestones. Alteration is minor.
Area structures include the porphyry dike that is an offshoot of the main sill of porphyry that consistently follows the contact of quartzite and limestone in this region. A major fissure plane, with NW strike, cuts the the Coronado Quartzite croppings between the Hormeyer Mine and Longfellow incline. The NE blcok is downthrown about 150 feet.
Workings include 2 tunnels or levels. Produced $30,000 of metals before 1902 (period values).
