SAMEX Makes Multiple Copper-Gold-Silver Intercepts & Further Defines Target at El Gringo

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 30, 2013) - SAMEX Mining Corp. (TSX VENTURE:SXG)(SMXMF) continues to advance its exploration at the El Gringo copper-gold-silver prospect, located within its 100% owned Los Zorros district in Chile. The company recently received back numerous lab assays which have given the geological team a wealth of knowledge regarding the prospect. Highlighted immediately below are the notable copper-gold-silver intercepts from the latest round of drilling:

"It is our opinion that these copper-gold-silver intercepts represent fingers of a very complex porphyry system with multiple mineralized events intersecting. We are methodically evaluating and following up on all this data with the goal of locating the main source of this strong mineralization," notes Juan Carlos Toro Taylor, Chief Geologist of SAMEX Mining Corp.

Drilling at El Gringo has totaled roughly 3,000 meters to date. Copper, gold, and silver mineralization is known to occur within the leaching, mixed, and primary zones. The observed mineralization is very complex, as different types are present and not confined to any specific domain or host rock.
