Obregon

Obregon was a historic gold mining community near the Cargo Muchacho Mountains and a frontier town that marked several attempts to extract ore from the 1890s through the 1930s. During its existence, several milling technologies were used, including a 20 stamp mill, Cornish Rolls, and a Hardinge Mill, all successively employed prior to 1913. In 1936, a floatation plant tried to extract gold from the meager ore before all mining ceased in 1939. Modern heap leach and conventional milling operations later continued the quest for gold, and in early 1989, American Girl Mining Joint Venture received the necessary governmental approvals to resume open pit and underground mining operations in American Girl Canyon. Before those operations began, the remains of the original Obregon townsite were thoroughly documented, and 5 graves circa 1892 were relocated to the Holtville Cemetery.
