Herencia Resources plc announced that it has commenced a significant drill program on its highly prospective Pastizal/Picachos copper field in central Chile. The drilling program will test the newly acquired Pastizal tenement abutting the Picachos lease and consist of 3,000 metres of Reverse Circulation (RC) drilling. Following the recent geological review of Herencia's copper properties Herencia has planned the drilling program to test under the current mine workings at Pastizal, Montenegro and Pastizal Norte as in green outline. Previous drilling during 2015 in the adjoining Picachos tenements, which hosts the same mantos mineralisation as Pastizal, intercepted mineralisation in 28 of the 29 drillholes with broad zones of medium grade copper interspersed with high grade copper intercepts within the mantos zones. The full details of the 2015 drill program are set out in the announcement dated 26 August 2015. One of the most interesting results of this style was drilled at the '40m Shaft' prospect where significant copper was intersected with; PP 14019 returning; 91 metres @ 1.42% copper and 13.5 g/t silver Including 20 metres @ 3.10% copper and 25.4 g/t silver. Another significant success in the field was at Picachos in 2014 where Diamond Drill Hole (DDH) 14003 targetting the southern end of the Picachos deposit successfully drilled down the dipping manto for approximately 250m intersecting good copper grade mineralisation as follows; 27m grading 1.18% Copper (Cu) from 182m, 30m grading 0.94% Cu from 213m, and 51m grading 1.44% Cu from 248m and opening up deep exploration potential in that area. DDH 14003 demonstrates that the main manto horizon has good potential for consistent grade and regular-shaped mineralisation and supports the geological review indicating these structures as the main target zones for Herencia's future drilling campaigns. Significantly, little drilling has been focused on the chert sequence in the Pastizal/Picachos field where XRF surface samples grading 7.54% and 3.77% copper have been measured.
