Other Targets
In addition to the large open pit deposit at Cerro del Gallo there are a number of low sulphidation epithermal targets that have only been partially tested. Additional drilling will be needed to fully evaluate the depth potential of these narrow silver-gold systems that were the focus of earlier programs largely because of the similarity of the vein systems to the prolific Guanajuato deposits (Figure 7).
Carmen-Providencia System
- The Carmen-Providencia quartz epithermal vein system is composed of three segments: Empalizada, Dolores and Espiritu Santo segments.
- Empalizada and Dolores are located 1.7km to the west of Cerro del Gallo. The Espiritu Santo segment is approximately 2km west of Cerro del Gallo.
- 14,570m were drilled with core and RC along the Carmen-Providencia vein system. 26 drill holes were drilled in Empalizada system totaling 6158m; 18 drill holes were drilled in the Dolores system with a total of 4075m and 14 drill holes tested the Espiritu Santo segment totaling 4,337m.
- The vein systems represent more than 3km of known strike length with a NNW trend, and dipping from sub-vertical to 75° with a west dip.
- Vein textures: Crustiforms, siliceous bladed (textures typical of an upper epithermal system). Alteration consists of argilic and silicic.
Ave de Gracia System
- The Ave de Gracia quartz epithermal system extends 1.5 km from the Dolores shaft to where the system intersects the west side of Cerro del Gallo.
- To date this system has only been tested by 460m of drilling in four RC doles.
- Upper low sulphidtion vein textures are present including crustiforms and banded textures, with significant adularia and visible sulphides.
San Luis Rey System
- The San Luis Rey epithermal system is located to 3.6km south of Cerro del Gallo.
- 13 drillholes (RC and DDH) were drilled totaling 1,768m.
- The vein system is known to extend for approximately 500m with a trend NE-SW and vertical/sub vertical dipping to SE.
