Utica Mine, the most important mine in the Angels District, set national records in the 1890's by producing more than 4 million dollars in gold in 30 months. It was also the site of Angels Camp's worst mine disaster, when 17 men were buried after the North Shaft collapsed in 1889, though three men escaped through the adjoining South Shaft. The bodies of those who died were recovered over a period of years, but the last two remained buried for 12 years. The Utica properties later expanded to include the Stickle, the Utica Cross-Shaft, and Gold Cliff Mines, and their combined production totaled 16.4 million dollars from 1887-1918, when Angels Camp's gold mining era ended.
