Exploration - Carlos Pecheco
Carlos Pacheco Prospect
The Carlos Pacheco is IMPACT's gold-copper discovery located 4.5 kilometers southwest of the Guadalupe Mill and 180 meters east of the 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).
Both the Noche Buena and Carlos Pacheco Veins have strike lengths in excess of eight kilometers, with numerous zones of enriched metal content as outlined by regional mapping and prospecting. To date, drilling has tested over 500 meters of strike length on these veins.
On July 11, 2012, IMPACT announced final drill results from the Carlos Pacheco Gold-Copper project. This drill program focused at depths of 120 to 250 meters, which is below an inclined shaft on the Carlos Pacheco Vein that IMPACT's mining group re-opened and sampled. This work indicated good continuity to the gold-copper grades for the Carlos Pacheco Vein and provided the impetus for this drill program.

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:

For this reason a lower economic cutoff is contemplated for the mining of these Intermediate Veins. The work of IMPACT's exploration team for this portion of the Carlos Pacheco and Intermediate Veins is now complete and the data has been passed to the mine planning group for engineering studies and potential production.
