San Juan Drill Intersections
VANCOUVER, BC - IMPACT Silver Corp. reported results from the next seven drill holes at its San Juan Project, located adjacent to the producing Noche Buena Mine. The Company is also pleased to announce initial field results from the new La Soledad and Pregones silver subdistricts located in the southeastern portion of its 623-square-kilometer concession holdings in the Royal Mines of Zacualpan area.
San Juan Project Drilling Highlights: This area of current drilling is testing the sub-parallel Noche Buena and Carlos Pacheco structures, which outcrop 170 meters apart and dip to the west. IMPACT is currently mining silver mineralization at its Noche Buena Mine, which is trucked east to the Guadalupe Production Centre, and has begun mining and stockpiling gold and copper mineralization from the nearby Carlos Pacheco Vein in preparation for processing in the Capire Production Centre to the south. The drill intersections in this News Release will be added to expand the mining plans for both gold and silver zones. A number of other recently discovered structures, such as the Tiburùn and Angel Veins, also occur in close proximity to the Noche Buena Vein.
Highlights from previous San Juan Project drill results include intersections of 17.1 g/t gold over 1.89 meters from the Carlos Pacheco Vein and 1,409.8 g/t silver over 2.07 meters from the Noche Buena Vein as well as 3.44 g/t gold over 7.17 meters from the Carlos Pacheco Vein and 1,587.8 g/t silver over 1.72 meters from the Noche Buena Vein (see IMPACT news release dated January 7, 2014).
Highlights from these new San Juan Project drill results include: Additional high gold grades for the Carlos Pacheco Vein of 10.343 g/t gold and 276.9 g/t silver over 3.19 meters, which includes a higher grade interval of 19.757 g/t gold and 502.6 g/t silver over 1.50 meters encountered in hole Z13-71, and 2.963 g/t gold over 3.38 meters in hole Z13-74. Wide intersections of silver mineralization for the Noche Buena Vein such as 14.40 meters grading 104.0 g/t silver in hole Z13-73 including a higher grade interval of 314.5g/t silver over 1.47 meters. significant intersections for the Tiburùn Breccia, which include 232.9 g/t, silver over 2.11 meters in hole Z13-69.
Additional assays are pending at the San Juan Project and additional drilling is planned. Because of the sub-parallel orientation of the Noche Buena and Carlos Pacheco Veins, IMPACT is able to intersect both veins in most drill holes, with the shallower Noche Buena and Tiburùn structures being drilled at 25-meter centers and the deeper Carlos Pacheco Vein on 50-meter centers. 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, where applicable, the integration of these intersections into the Company's mining plans. The Carlos Pacheco Vein remains open for expansion at depth and to the south where an increase in both the gold and copper grades has become evident.
Emergence of the La Soledad and Pregones Subdistricts: Since 2012, Impact’s exploration team has been conducting preliminary investigations in the southeastern portion of its large concession holdings at Zacualpan. La Soledad and Pregones areas, located nine and fourteen kilometers southeast of the Guadalupe Production Centre, respectively, were selected for detailed geological mapping and rock sampling.
La Soledad Subdistrict: Work on La Soledad Area is more advanced, with the collection of over 1,800 rock samples from outcrops, trenches and some 350 old mine workings. Over 1,200 of these samples contain assays greater than 100 g/t silver with 21 having more than 1,000 g/t silver. La Soledad Vein, a prominent northeasterly dipping structure, has received the most work, having been delineated for a strike length 1.5 kilometers through the collection of some 800 rock samples. Defining the central core to this vein are seven rock samples containing values between 1,060 and 2,700 g/t silver. Several other structures occur in close proximity to La Soledad Vein, such as Doûa Estela, El Diablo, El Tejùn and El Comal, all of which contain significant silver grades as well.
Pregones Subdistrict: At the Pregones Area, where fieldwork began in September 2013, IMPACT has located 43 old mine workings, as well as five ancient processing plants. From nine of these old mine workings, 267 rock samples have been collected, 125 of which contain grades greater than 100 g/t silver and 21 are greater than 500 g/ silver. Many more old mine workings occur in the Pregones area as evidenced in a mining report dated 1908 indicating locations for 89 old mine workings and eight old processing plants. Historically, the Pregones or Precones District as it was called in the 18th century was an important center of past production, having the highest density of old processing plants for this portion of Mexico. For that reason, the Pregones District was historically considered to be on a par with Zacualpan and Taxco in terms of economic importance and was, coincidently, situated midway between them. The important veins of the Pregones District, such as the Poniente, La Negrilla and τguila dip primarily to the northeast, although some southwesterly dipping veins are known. At the historic La Negrilla Mine, rock samples containing significant silver values have been collected along the entire 162-meter length of this old mine drift.
