The E1 Sauzal gold-silver deposit is situated in the western Sierra Madre Occidental of Mexico, near the border between the states of Chihuahua and Sinaloa (Fig. 1). The deposit was discovered in 1995 by Francisco Gold during grass-roots exploration centered on the historic silver district of Batopilas, about 15 km to the NE (Fig. 1), (Charest et al., 2004). Colonial-era and other significant workings were completely absent at El Sauzal. Geologists travelling by mule and on foot in the deep, roadless canyon of the Rio Urique made the discovery by direct rock-chip sampling of resistant, highly altered outcrops. Between 1996 and 1999, a camp was established and a total of 188 diamond-drill holes were completed. Drilling was focused on the potential for shallow, oxidized ores and was largely guided by gold in rock-chip and channel samples.
