More High Grade Silver and Gold Encoungtered Adjacent To Noche Buena Mine
VANCOUVER - IMPACT Silver Corp. reported second phase drill results from the San Juan Project, located 150 meters north of its producing Noche Buena Mine and four kilometers southwest of its 500-tpd (tone-per-day) Guadalupe Production Centre. The San Juan Project area encompasses a series of large old mine workings containing multiple working levels that previously exploited the gold-rich Carlos Pacheco Vein within the Valle de Oro sub-district of the Royal Mines of Zacualpan Silver-Gold District of central Mexico.
Previously, IMPACT reported drill intersections of 1,409.8 g/t silver over 2.07 meters from the Noche Buena Vein and 17.1 g/t gold over 1.89 meters from the Carlos Pacheco Vein. The Noche Buena and Carlos Pacheco Veins are parallel structures that outcrop approximately 170 meters apart, striking north-northwest and dipping to the west.
Highlights from these new San Juan Project drill results (see table below) include: Additional high grades for silver in the Noche Buena Vein encountered in hole Z13 60: 1,587.8 g/t silver over 1.72 meters true width as well as significant intersections in holes Z13-62, Z13-64, Z13-65 and Z13-67; Additional high grades for gold in the Carlos Pacheco Vein encountered in hole Z13 67: 3.439 g/t gold over 7.17 meters true width, which includes a higher grade interval of 39.20 g/t gold over 0.53 meters true width; other wide intersections of gold-silver-lead-zinc-copper mineralization for the Carlos Pacheco Vein were intersected in holes Z13-47 (3.08 m), Z13-48 (4.14 m), Z13-50 (3.81 m) and Z13-66 (5.11 m); The discovery of a number of new silver-gold-lead-zinc structures such as the Tiburùn and Delfin Breccias; the Cangrejo, La Jaiba and Langostino Veins, plus a significant extension to the Abulùn Vein, all of which were encountered in the near-surface portions of drill holes intended to explore the deeper portions of the Carlos Pacheco Vein; Significant intersections for the Tiburùn Breccia include 179.4 g/t silver over 5.10 m true width in hole Z13-59 and 160.0 g/t silver over 3.62 m true width in hole Z13-67, with the Abulon Vein returning 105.8 g/t silver over 3.27 m true width in hole Z13-64 and 214.7 g/t silver over 2.29 m true width in hole Z13-65.
Mining operations at the Noche Buena Mine have been moving progressively northward and are now integrated with the San Josa underground workings, thus providing access to the Noche Buena Vein near the area of this current drilling. A crosscut decline has also been started to access the Carlos Pacheco Vein in this area.
Drilling is ongoing on the northern extensions of the Noche Buena and Carlos Pacheco Veins and because of the parallel orientation of these veins, IMPACT is able to intersect both Noche Buena and Carlos Pacheco in most drill holes; the shallower Noche Buena Vein is being drilled at 25-meter centers and the deeper Carlos Pacheco Vein at 50-meter centers. In addition, other structures are now contributing significant intersections within the immediate area of the San Josa underground workings near where the Noche Buena Vein is currently being exploited. The Tiburùn and DelfÆn Breccias plus the Abulùn, Cangrejo, La Jaiba, and Langostino Veins are also being drilled at 25-meter centers, which is helping with the interpretation and integration of these intersections into IMPACT's mining plans. The Carlos Pacheco Vein in this area remains open for expansion at depth and to the south where an increase in both gold and copper grades has become evident (see the Carlos Pacheco Drill Hole Long Section Map, available on the Map Room page on the Company website at www.IMPACTSilver.com).
Detailed mapping by IMPACT's exploration department, along with rock sampling, prospecting and surveying, continues to the north of the San Josa underground workings where all seven of the silver-gold-lead-zinc-copper bearing structures that are currently being drilled are known to extend. This work has resulted in the discovery of several important vein outcroppings, upon which additional drilling will likely follow once this field work is complete in order to outline additional mineralization in this newly discovered area.
