JOGMEC Confirms Cu-Au Resources in Chile
Japan Oil, Gas and Metals National Corporation (JOGMEC, President Hirobumi Kawano) has confirmed
prominent copper-gold mineralization at Los Helados in Chile from the additional drilling surveys JOGMEC
has conducted jointly with NGEx Resources Inc., headquartered in Vancouver, Canada. From these favorable
results, hopes are raised that it is highly likely the area hosts economically minable copper-gold deposits. Thedrill core assays show the following positive results: 701 meters of 0.67% copper and 0.30 g/t gold (holeLH-16), 575 meters of 0.59% copper and 0.33 g/t gold (hole LH-17), and 312 meters of 0.73% copper and 0.35
g/t gold (hole LH-20). Further drilling surveys are necessary for highly accurate calculation of provable
reserves in the area but such significant

results from this year’s drilling have hightend expectations fordiscoveries of more mineralization in the extended area.
The detailed survey results from this drilling campaign will be presented in the JOGMEC’s second metal
resources briefing (conducted in Japanese) at its headquarters in Tokyo on June 3rd, 2011.
The Andean Cordilleras is considered as one of the last frontiers where large-scale copper mines could bedeveloped. However, due to its inaccessible location, it has not been sufficiently explored in spite of its highpotential for the existence of mineral deposits. JOGMEC has focused attention on its potential and has
conducted exploration since the initial phase of 2004 even when drilling had not yet begun.

Outline of the Frontera Project
The Frontera area is located in the Andean Cordillera straddling the border between Chile and Argentina, covering
part of the Region III in Chile, northwestern San Juan and southwestern La Rioja in Argentina. JOGMEC signed aJoint Exploration Agreement over Frontera with NGEx Resources Inc. (then Suramina Resources Inc.) and its
subsidiary companies in Chile and Argentina on 1 February, 2008. JOGMEC has a right to acquire its 40% equity
interest. In addition to Los Helados, it consists of promising properties like Filo del SolResults of Drilling Surveys in Los Helados
The drilling surveys, with ten drill holes completed with a total of 7,404m, were carried out in Los Helados,
located on the Chilean side of the JV property, from December, 2010 to April, 2011 as a part of the surveys in theFrontera project area which straddles the Argentina –Chile border.
