Orex Minerals Inc.: Third Drilling Rig Added to the Coneto Gold-Silver Project in Durango, Mexico

Marketwired

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 25, 2013) - Orex Minerals Inc. (TSX VENTURE:REX) ("Orex") is pleased to announce that a third diamond drilling rig has been added to the Coneto Gold-Silver Project in Durango, Mexico. A technical committee, with representation of Orex and its project partner Fresnillo PLC (FRES.L) ("Fresnillo"), is managing this Phase-II program. In addition, the results of the third batch of assays from the 12,000 metres Phase-II diamond drilling program are now available.

Reconnaissance drilling to date on the Coneto Project has yielded intercepts in six mineralized structures, including Loma Verde, Impulsora, La Bufa, Santo Niño, Sauces and Descubridora, identifying them as targets for delineation drilling.

Hole BCO-17 in the Descubridora vein yielded an intercept of core length of 6.45 metres (true width 4.84 metres) grading gold 0.71 g/t and silver 153 g/t, for a gold-equivalent of 3.49 g/t, or silver-equivalent of 192 g/t.

Hole BCO-28 in the Impulsora vein yielded an intercept of core length of 7.60 metres (true width 4.56 metres) grading gold 2.04 g/t and silver 12.3 g/t, for a gold-equivalent of 2.27 g/t, or silver-equivalent of 125 g/t.

According to Orex's President, Gary Cope, "We are very encouraged by the number of structures being identified in the reconnaissance drilling for additional follow-up. Coneto is indeed a very large mining district, with multiple targets."

Silver-equivalent for the purposes of this news release is defined as silver grade plus 55 times gold grade. Gold-equivalent is defined as gold grade, plus silver divided by 55. The 55:1 ratio is based on the spot prices of silver $28.90/ounce and gold $1596/ounce. Metallurgical recoveries and net smelter returns are assumed to be 100% for the equivalent values. Base metal values are not included in the equivalent values.

Coneto Mining District - Durango, Mexico

The historic Coneto Mining District is situated in the heart of the "Mexican Silver Trend", stretching from Guanajuato in the southeast, through to the states of Zacatecas and Durango. The trend hosts some of the world's largest silver deposits, including Fresnillo, Guanajuato, La Pitarrilla, Real de Angeles, and Zacatecas mining camps.

Orex and Fresnillo hold extensive contiguous mineral concessions in the Coneto Mining District, which collectively total approximately 17,600 hectares and cover an extensive area of known mineralized epithermal quartz veins. The project is located in the Mesa Central, on the eastern flank of the Sierra Madre Occidental Mountains.

Ben Whiting, P.Geo., is a Qualified Person as defined in NI 43-101 and takes responsibility for the technical disclosure contained within this news release. The drill core sampling has been conducted with a rigorous QA/QC program, incorporating analytical standards and blanks into the sample stream. Analyses were performed in the laboratories of ALS Chemex.

The first twelve holes of the current drilling program of Coneto, were reported in news releases on November 7, 2012 and January 7, 2013, following the successful Phase-I drilling program (see news releases: July 6, 2010 and August 9, 2010).
