The following is an excerpt translation from: Soriano, H. R., 2011, EL DISTRITO MINERO DE EL TRIUNFO-SAN ANTONIO, B.C.S., MÉXICO. CARACTERÍSTICAS Y PROBLEMÁTICA:
"The mining district is located on a batholith called "Plutonic Complex of La Paz" (Ortega Gutierrez, et al. 1992), which is largely [comprised of] intrusive igneous rocks granites and granodiorites dominate the Upper Cretaceous, but are also tonalites, diorites and [quartz-diorites of] different age. [Less common] are metamorphic rocks, including shales predominate[ly] and biotite gneiss, whose general [foliation] orientation is NE with slopes of 45° to 75° to the SE. [T]hese rocks are considered the oldest, although its age is not considered fully defined Jurassic or earlier. [This igneous and metamorphic material] is intruded by various types of Cenozoic subvolcanic rocks, which
were predominantly [emplaced as andesite, dacite, and aplite] dikes. Surface rocks are covered by alluvial deposits [and] conglomerates [of] Quaternary [age], covering partially mineralized structures especially in the plains and streambeds.
[T]wo regional [fault] systems define the block where the district is located, one represented by the faults with a predominant N-SW direction and one in the Santiago failure whose orientation is NE-S.
In metamorphic rocks, the mineralization is predominantly [in] shale in vein type structures, [and] in the contacts between granodiorite and tonalite intrusions and [in] quartz-forming deposits in shear zones (type stockwork and porphyry gold), where first and subsequently fractured quartz-mineralized sulphide-rich solutions [have] generated supergene oxidation zones and surface enrichment. [M]ineralization primarily is being made by hydrothermal minerals arsenopyrite, sphalerite, galena, and secondary mineralization consists of oxides and hydroxides of Fe, among others.
Initially the mineralized zones were exploited by the Spaniards, who were focused on oxidation zones and enrichment Supergene, then from 1892 [by] American and British [comapnies]. [T]hey focused on the exploitation of sulfides with a series of underground mining works on the main veins. [Early operations used simple fireplaces] to reduce the minerals. This operating period ending in 1910, due to the start of the Mexican Revolution.
After the revolution, there were several attempts by the federal government and private companies to revive the district, which did not have the expected success and the area was [only semi-active for]
several years."
