Located off the Masonic Road between Bridgeport, CA and the Masonic town site, are the remains of the Chemung gold mine. The Chemung gold mine operated from from 1909 to 1938 and produced over one million dollars in gold. In the 1920s, the Chemung mine was producing low grade and high grade ore. The ore was processed onsite, and then shipped to near by Bodie for smelting.
In around 1900, Stephen “Steve” Kavanaugh was hired to dig a gold vein that ran along what would later be named Kavanaugh ridge. He established the Chemung Mine, which he named after his hometown in Illinois, but did not receive a share in the mine’s profits.
