San Judas is at the southern end of the Caborca Orogenic Gold Belt or Sonora Mojave Mega Shear. A trend known to host several orogenic and related intrusive gold-bearing deposits within an area that extends from north-western Mexico into the southwestern United States; and measures more than 600 km long by 60-80 km wide. There are several large open pit heap leach gold operations within the Caborca Orogenic Gold Belt deposits including Magna’s newly acquired San Francisco property/mine. Others are La Herradura, Soledad-Dipolos and Nochebuena (Fresnillo PLC), Cerro Colorado (Gold Group), El Chanate (Alamos Gold Inc) and La Choya (Hecla Mining). The combined gold reserves and resources identified within the trend to date total in excess of 10 million ounces of gold (Izaguirre et al., 2017) but this figure could be double (~20 million ounces) according the current exploration results and plan of the biggest gold producer in the region.
