Rock Samples At Santa Teresa Gold-Copper Area

 

VANCOUVER - IMPACT Silver Corp. reported an exploration update on continuing rock sampling in the Santa Teresa Area of the Royal Mines of Zacualpan District in central Mexico. Recent results from the El Canelo vein systems at Santa Teresa averaged 6.5g/t gold over a true width of 1.66 meters along a strike length of 50 meters. The system remains open for expansion and parallel vein systems in the area are being mapped and sampled at this time.  

The strong gold potential of the general area was first recognized by IMPACT geologists between 2008 and 2013 while drilling the Carlos Pacheco and San Juan areas 1.5km to the north. They are probably northern extensions of the Santa Teresa mineralizing system. Some of the Carlos Pacheco mineralization saw test mining in 2013-2014 but most of the zone remains in place available for future mining.

The Santa Teresa area is located approximately five kilometers to the southwest of IMPACT's Guadalupe processing plant and has been a mapping and prospecting target area over the past year.  The area was selected for a detailed exploration program to more clearly define the source of strongly anomalous gold and copper soil geochemistry. Mapping and sampling in 2012 located a series of porphyritic rhyolite intrusions that appeared to be related to gold bearing quartz veins, breccia veins and alteration zones that returned values up to 18g/t gold over a sample width of 1.3m and 34g/t gold over 0.50m. Initial results were reported earlier this year.

The Santa Teresa-Carlos Pacheco project extends over an 800 hectare area cut by gold and silver-bearing veins.  Outcrops of Eocene feldspar porphyry rocks in the Santa Teresa area are the only known magmatic intrusive rocks within the Zacualpan district and probably represent a heat engine that drove mineralizing fluids.  Rock samples from these feldspar porphyries themselves return moderate values for precious and base metals, however silicified and brecciated portions of the host rock adjacent to and above the feldspar porphyries have numerous high gold values (up to 17.95 g/t) presenting a potentially intriguing bulk tonnage exploration target in addition to the gold vein targets.  

Fred Davidson, President of IMPACT, stated "This recent work has given us a new understanding of the bulk tonnage potential of the Santa Teresa area which is located within trucking distance of our operating Guadalupe processing plant. Santa Teresa appears to be a larger zone in the core of the Zacualpan district where a deeper and hotter part of the mineralizing system indicates potential for a copper and gold bulk tonnage target. Our field crews are continuing to work diligently to advance the area including plans for drilling."
