The Property is in the Sierra Madre Occidental (SMO) mountain range of the North American Cordillera that extends for hundreds of kilometers from central to northern México in the Basin and Range province (Rossotti, Ferrari, Lopez-Martinez, & Rosas-Elguere, 2002). The SMO is a large continuous sequence of volcanicsthat spans in age from late Cretaceousto middle Tertiary (McDowell & McIntosh, 2012).

The mineralized zone is characterized by a low sulphide epithermal system containing silica stockwork veins. These zones are generally formed in felsic subaerial complexes in extensional strike slip structural settings. Low sulphidation gold deposits are associated with magmas where ore deposition occurs several kms above the intrusion, and display certain alteration assemblages (Cooke & Simmons, 2000). The intrusions are likely the result of tectonic activity, such as plate subduction and extension. Deep hydrothermal fluid flow systems comprised of meteoric water, as well as near surface systems such as hot springs, are the sites of mineralization. Mineral deposition takes place as the fluids undergo cooling by fluid mixing, boiling and decompression.

Mariposa-El Zapote-Tahonitas Trend
The Mariposa-El Zapote-Tahonitas structure strikes to the south-southeast and dips at approximately 50° to the southwest. Mariposa is the northernmost deposit along the mineralized trend and has a length of approximately 750 m. The structure at Mariposa is at the contact ........

The Guadalupe de los Reyes Project has been divided into East and West areas. The West area open pits are El Zapote North, El Zapote South, San Miguel North, San Miguel South, and Noche Buena. The proposed mining methods for the Guadalupe de los Reyes deposit is conventional open pit methods utilizing off-highway trucks and loaders. Mining is proposed to occur sequentially in five open pits.

The West area pit designs incorporate a 50 degree inter-ramp pit slope depending on rock type. Bench configuration is based on triple benching 5-meter benches with a dig-face angle of 70 degrees. The majority of benches were designed with five-meter-wide benches with 7- meter catch benches. Catch benches were designed at every third bench.

Haul roads were designed for a total width of 15 meters, which accommodates the main haul surface, berms, and ditches. All haul roads were designed not to exceed 10 percent gradients. This haul road width and grade will support the selected truck size.
