The company also held a number of the major properties in the El Triunfo-San Antonio gold district south of La Paz in South Baja. The mines were opened by the company in 1863. It included the Carmen, Santa Fe, Valenceina, Mendocena, and Esperanza. A tunnel was driven to cut the Carmen vein which was described in a correspondent letter to the Mining and Scientific Press: t the spot where the vein was cut, I measured seven feet of metal, and if I am any judge, it would be difficult to find anything to surpass it in average richness. A stockpile of ore at the mill was reported to average of twelve hundred dollars per ton (equivalent to 60 ounces gold per ton!). The correspondent further stated that; and without a doubt, it (the El Triunfo valley) will become a place of much importance, as there are numerous mines, as rich probably as any on the Pacific coast, within a view from the site of the Triunfo Companyworks. The El Triunfo mining district has probably produced more than 500,000 ounces of gold from discovery to the present.
