VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 31, 2013) - SAMEX Mining Corp. (TSX VENTURE:SXG)(OTCQB:SMXMF) is ready to advance exploration efforts at its 100%-owned Los Zorros project in Chile. The Company is hereby outlining parameters for an upcoming drill program at El Gringo, a copper and gold prospect located within the approximately 80 square kilometer land holdings of Los Zorros. Numerous surface mine workings are found throughout this prospect where copper and gold are believed to have been extracted by artisanal workers in the late 1900's. El Gringo has not been systematically explored or drilled by any prior geological team to date.
SAMEX proposes drilling an initial 5 boreholes (570 meters) to evaluate primarily copper and gold potential throughout El Gringo, as shown on the accompanying graphic plates at www.samex.com. The central coordinates of El Gringo are N 6907000 and E 359716, with heights ranging between 900 and 1000 meters above sea level (Figure N° 1).
This drilling campaign will explore this area which is highly structurally controlled, where at least two episodes of alteration and mineralization have been identified. One is defined by manto-type mineralization containing copper and gold, while the other is comprised of feeders associated with copper and gold breccias (Figure N° 2). The entire area is underlain by a thick sequence of volcanoclastics associated with lava flows, limestone, siltstones, quartzite and calcareous rocks. Below this mentioned sequence, dioritic granodiorite intrusives of the Upper Cretaceous age are found. Feeders are abundant in an average direction of 320° azimuth.
The El Gringo mineralized area is part of a hydrothermal system, differing from copper porphyries but of close association. The target model is a combination of manto-type mineralization associated with exoskarns and abundant epithermal feeders. This mineralization appears to extend for over 400 meters in width and at least 800 meters in length, while the bulky mineralization is approximately of 360-330° azimuth dipping slightly 15°SE. Abundant copper oxides, specularite, gold, garnets, chlorite, high silicification, carbonates, Fe oxides, wollastonite and manganese have all been found throughout fractures disseminated along wall rocks of the feeder.
This drill program involves a preliminary 5 diamond drill holes with an average depth of 114 meters for a total of 570 meters (Figure N° 3 & Table 1). In the event that meaningful visible mineralization is encountered, drilling will continue to greater depths in order to assist in quantifying tonnage potential.
Bulldozer work is currently in progress to construct access roads and drill pads in preparation for drilling at El Gringo, which is expected to commence shortly. SAMEX anticipates further updates on this program in the near future.
