La Muralla Project
•Located in Southwest Chihuahua, Mexico. Within the Sierra Madre Occidental trend of historical mines and developing projects.
•21 kms South of Batopilas Silver Mining District (1708 – 1920) which produced over 300 M ounces silver from high grade veins and structures, including native silver.
•25 kms East of El Sauzal - Gold Corp (New Mont) which produced over 1.7 million ounces of gold.
•45 kms West of Plata Verde- Fresnillo, this project was recently acquired by Fresnillo and is under exploration.

Geophysics / IP and Resistivity Tomography
Surface geophysics as deep as 350 meters shows high chargeability anomalies, meaning there is a high possibility of deeper continuity of a large ore body or larger veins.
Shallow geophysics was taken as deep as 65 meters and it shows continuity of the surface veins probing there is continuity.

Dios Padre Mine
Geological mapping on haul level.
The mineralization in the mine is located in the Dios Padre fault vein.
The average thickness of 0.2 m with a general direction NE70°SW dipping to the SE and inclination of 40° to 60°.
The lithology of the area consists of Tertiary andesites (lower volcanic group) and subvolcanic intrusive bodies in the form of small dikes intruding the andesites. These dikes are related to mineralization.
Intrusive of very compact dioritic composition with strong magnetism.
Porphyritic quartz-feldspathic intrusive encased the mineralized zone.
