Defiance's Phase 1 Drilling Significantly Expands High Grade Mineralized Envelope at San Acacio
Vancouver, British Columbia--(Newsfile Corp. - October 25, 2017) - Defiance Silver Corp. (TSXV: DEF) (OTC: DNCVF) ("Defiance") is pleased to announce results from the final holes of its Phase 1 drilling program including a 3 meter intersection grading 404 g/t AgEq within a longer 10 meter intersection grading 204.65 g/t AgEq.Defiance commenced its 5000m drill program to test the extension of the San Acacio Deposit at depth.Including the final holes, Phase 1 has extended mineralization up to 230 meters below the current resource.
"We are very pleased with our continued exploration success at San Acacio.The Phase 1 results significantly expanded the mineralized envelope of the San Acacio silver deposit. Mapping and mineralogical studies indicate that the mineralized system hosting the San Acacio deposit is tilted to the southeast. This suggests that drilling along strike could result in the discovery of new mineralized zones containing the full vertical extent of the mineralizing system. Our next step is to prepare for the commencement of an aggressive Phase II drill program targeting new high grade shoots within the 900 meter extension of the Veta Grande vein system to the southeast of the San Acacio deposit," stated Roy Bonnell, President and CEO of Defiance Silver Corp.
Along the entire Veta Grande vein, which pinches and swells along strike, approximately 200 million ounces of silver was historically produced from high grade shoots in the swells. Defiance's portion of the Veta Grande vein has produced an estimated 100M ounces from high-grade shoots such as those that host the San Acacio deposit.Over 4.4 km of Defiance's 5.6 km holdings along the Veta Grande vein have not seen historical production nor been systematically explored.Mapping, sampling and drilling has indicated that pinching and swelling continues along strike, presenting significant potential for the discovery of multiple, new, intact silver shoots.
Drill holes SAD17-13 and SAD17-14 targeted the Esperanza Zone, extending the mineralization to depth below drill hole SAD17-12 which intersected high grade silver over a core length of 27.03 meters of hydrothermal breccia and veins assaying 202.99 g/t AgEq (see News Release dated June 8, 2017). Drill hole SAD17-13 extended the wide zone of mineralization returned in drill hole SAD17-12 with a 10 meter intersection grading 204.65 g/t AgEq. Drill hole SAD17-14 intersected three narrower zones of mineralization before intersecting a fault that displaced the main vein.Drill hole SAD17-15 drilled 100 meters to the southeast on the vein intersected high grade mineralization grading 296.30 g/t AgEq over 3.18 meters. Drill hole SAD17-17, drilled 100 meters farther to the southeast, extended the wide vein intersection of 11.95 meters returned by drill hole SAD15-10 although mineralization was primarily base metals suggesting that it may be in the low grade zone between the silver and the silver-base-metal zones.
With the completion of its Phase 1 drill program, Defiance presents highlights from its recent drilling as part of a complete table of all Phase 1 results (including those previously reported)
