In the South Central portion of the State of Arizona, well within the Empire of Mexico, lies the Mogollon Mountains. During the Texas-Mexico War of 1872, Chiricahua Apache warbands with the 1st Texas Cavalry Regiment clashed with Imperial forces in the region in an effort to secure more territory for the Republic. During the raids, it was discovered that the area was rich in gold and silver but the Texians could not secure the area so far from supply lines. They blasted what they could, and left the area in hopes the Imperials would not find the seam.
March 1880, settlers from Mexico City on the way to Baja find gold in a range called the Gila Mountains, a southern section of the Mogollon Mountain range. Word is sent to Mexico City and a small gold rush is underway as Mexican prospectors swarm in for a chance to strike it rich.
