SAMEX Mining Corp. Expands El Gringo Drill Program and Provides Chimberos Update

VANCOUVER, 02/27/13 - During the course of its initial drill program at the El Gringo copper and gold prospect at Los Zorros, SAMEX (TSX VENTURE: SXG) (OTCQB: SMXMF) has decided to expand total drilling activity from the previously announced 570 meters to a new total of 1200 meters. Drilling presently continues while numerous core samples have already been sent to the lab for rush-assaying. Detailed images of the entire core completed so far from holes EG-13-001 and EG-13-002 are now available for viewing at www.samex.com within the Coreshack section.

"In order to improve transparency at SAMEX, I strongly believe in making photos of newly-drilled core available for viewing as soon as it is practical to do so. The goal is for shareholders to be able to better follow our exploration progress as updates are regularly announced," said Sasan Sadeghpour, Chairman and Chief Executive Officer. "The geological team and our Board of Directors consider this to be important for shareholder awareness. However it is imperative that investors not make any assumptions regarding possible mineralization types or grades until certified lab results are announced."

SAMEX is also in the process of updating exploration plans at the Chimberos Property to follow up its prior geological team's recent drilling campaign. A detailed review of the drill core and partial assays received back so far indicate preliminary evidence of a series of events relating to a hydrothermal system, near what could be productive porphyries and breccias. Results will be announced in due course once all logging and assaying has been completed.
