From the 1880s to the early 1900s, it passed through the hands of a number of Tucson-based firms, but never returned much of a profit during that time. Mowry, named after Lieutenant Sylvester Mowry, was originally called the Patagonia. After Mowry purchased the mine, he changed the name and erected smelting equipment, buildings, and a smelter. Then, the civil war came and the Indians ran most white folk out of the territory, specifically reducing Mowry to ruins. After the war Mowry again sprung into life and mining continued through the early 1900's.
Today there is a small cluster of wood and adobe rubble and a small cemetery.
