VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 13, 2011) - Oro Mining Ltd. ("Oro Mining" or the "Company") (News - Market indicators) is pleased to provide the following updates:

Project Update

In addition to the ongoing sonic drilling campaign at its Taunus deposit in Sinaloa, Mexico, Oro Mining has commenced a 2,000-metre diamond drill program at its high grade gold-silver vein hosted El Compas property, located in Zacatecas, Mexico. The objective of this drill program is to increase and upgrade the gold and silver resource base through a combination of infill, expansion, and exploration drilling at the El Compas and El Orito resource areas. 

Twelve diamond drill holes are planned at the El Compas and El Orito resource areas. The expansion and exploration drilling will focus on extending known high-grade gold and silver vein structures.

The Company also reports that in addition to the completed purchase of 100% ownership of the El Compas concession, Oro Mining has completed the purchase of certain surface property rights covering 12 hectares of strategically located land sighted for mine ramp access and waste rock disposal. The Company also has a 24-month option to purchase an additional 25.5 hectares of adjacent land suitable for plant construction. "The procurement of surface rights is an important milestone on the development of the El Compas mine as it will allow unhindered mine access for the eventual exploitation of the deposit. We believe that this was a necessary requirement prior to conducting additional exploration activities on the deposit. Now that we own 100% of the concession and have acquired surface rights we will quickly evaluate the regional upside potential," said John Brownlie, CEO of Oro Mining.
