The principal veins of the Mirasol area represent a shear zone in which the veins strike northwesterly and dip to the southwest. The Mirasol Central and Mirasol NW Zones remain open in all directions. Drilling is continuing to expand the zone.
Carlos Pacheco Gold-Copper Zone
The Carlos Pacheco Gold-Copper Vein is located 4.5 kilometers southwest of IMPACT'S Guadalupe Processing Plant and 180 meters due east of IMPACT's currently producing Noche Buena Mine. It is a west dipping structure running parallel to the Noche Buena veins. Stratigraphic studies indicate that the Carlos Pacheco mineralization was emplaced 560 meters deeper than the Noche Buena mineralization; however, subsequent faulting juxtaposed these two zones. Consequently it is one of many zones within the central part of the Zacualpan project area that represent a deeper part of the mineralizing system enriched in gold and copper. Fieldwork in the Carlos Pacheco area began in 2007 with a systematic mapping and rock sampling program followed by an initial drill program that cut high grade gold intersections of up to 19.6 g/t gold across 2.9 meters including 49.7 g/t gold across 1.0 meter (see IMPACT News Releases dated January 18, 2007 and December 4, 2008).
In 2012, additional drilling at depth on Carlos Pacheco returned more significant assays as follows:

Located between the Noche Buena and Carlos Pacheco Veins are ten Intermediate Veins intersected during drilling that targeted the Carlos Pacheco Vein. These Intermediate Veins represent a vein cluster located midway between the Noche Buena and Carlos Pacheco Veins that include numerous wide, lower grade intersections of silver, gold, lead and zinc.
Summarized below are some of more significant intersections from the Intermediate Veins:
