History

The town was named after Saint Rosalia, although the mission is not located by the town, but is in original location Mulegé, about south. Santa Rosalía boasts French influence, particularly in its architecture. The French Compagnie du Boleo founded the town in 1884 and exploited

s have been identified. El Boleo was mined by Compagnie du Boleo, a French company, from 1885 until 1954. To prevent the economic collapse of Santa Rosalia and surrounding communities, a Mexican state-owned company (CMSRSA) assumed control and reopened the works using basically the same (rather archaic) equipment and process used by the French. The government funded operation was never profitable, and the mine was finally closed in the 1980s, when lower-grade ore and old technology made continued operation impractical.


Modern mining efforts

Baja Mining, a Canadian firm, began intermittent exploration of the El Boleo mine and subsequently undertook an effort to reopen El Boleo. Baja Mining estimated that the property contains a resource of 534 million tons of ore, containing 0.59% Cu, 0.051% Co, and 0.63% Zn. Baja also hoped to produce byproduct

. Baja Mining, in partnership with a Korean Consortium began developing the $1.6 Billion project in 2010. In 2012 however, construction cost overruns reported by Baja Mining threatened to halt or delay construction of the project. Majority ownership interest and control of the project was transferred to the Korean consortium, in return for funding the reported cost overruns. On January 26, 2015 Minera y Metalurgica del Boleo obtained its first copper production from the process of crushing, leaching, extracting and electrowinning in its mine-metallurgic project "El Boleo".

Climate

Due to its location in the warm Gulf waters, which are considerably warmer than Pacific waters in the winter, the town is the northernmost (and thus closest to the US border) year-round warm locale on the main peninsular highway. Nevertheless, it's not much of a tourist town and sees few snowbirds.


Demographics

The 2020 census showed a population of 14,357 persons. The population was 10,190 in 1990.
