Oro Gold and Oro Silver Enter Into a Business Combination Agreement

Vancouver, British Columbia -- (Marketwire) -- 08/11/10 -- Oro Gold Resources Ltd. (\"Oro Gold\") (TSX VENTURE: OGR) and Oro Silver Resources Ltd. (\"Oro Silver\") (TSX VENTURE: OSR) today jointly announce that they have entered into a binding letter of agreement (the \"Agreement\") to combine the two companies through a plan of arrangement (the \"Transaction\"). Under the Agreement, Oro Gold and Oro Silver have agreed, based on the recommendations of their respective special committees comprised of independent directors (the \"Special Committees\") in consultation with their advisors, that the Transaction will be an all-share transaction whereby Oro Gold would acquire all of the outstanding securities of Oro Silver on the basis of four common shares of Oro Silver for each common share of Oro Gold (the \"Exchange Ratio\").

The combination aligns with Oro Gold's corporate strategy of making low-cost acquisitions of gold ounces in under-explored mining camps that have significant expansion and discovery potential. Oro Silver's flagship property, El Compas, has excellent growth potential.

\"With Oro Silver's assets becoming gold dominant, the strategy of the combined companies will simplify the corporate structure, consolidate management and reduce costs. This transaction will put us in a strong position to create value for our shareholders by having two low-cost gold assets with near term gold production and significant resource growth potential through exploration,\" stated Darren Bahrey, President and CEO of Oro Gold and Oro Silver.

Oro Silver shareholders will benefit from Oro Gold\'s strong liquidity and market position combined with participation in the exploration and development potential of Oro Gold\'s substantial Mexican property portfolio including the advanced Taunus deposit. The value of the offer provides Oro Silver shareholders with an approximate 11% premium to the preceding 20 day volume weighted average share price. Oro Silver stock options and warrants will be converted to Oro Gold stock options and warrants at the Exchange Ratio.


Key Points:

-- Combining both companies creates a better capitalized, more liquid company with a focused management team that brings an impressive track record of past successes in gold exploration and mining to the expanded asset portfolio.

-- The combined entity will have two near-term gold production properties located in Mexico with excellent infrastructure and resource growth potential through exploration.

-- Oro Silver's core asset is the El Compas gold-silver property which has a NI 43-101 compliant resource of 65,000 gold-equivalent ounces in the indicated category (grading 5.8 g/t gold and 59.1 g/t silver) and 41,200 gold-equivalent ounces in the inferred category (grading 4.9 g/t gold and 45.7 g/t silver), using a 3 g/t gold-equivalent cut-off (See press release dated November 12, 2008).

-- Oro Gold's core asset is the Taunus gold deposit which has a NI 43-101 compliant inferred resource of 200,930 ounces (4.5 million tonnes at an average gold grade of 1.4 g/t, using a 0.5 g/t gold cut-off (See press release dated July 2, 2008).

-- Post transaction, Oro Gold will have approximately 84 million common shares outstanding and cash in excess of $5 million to continue its exploration activities, and to complete resource estimation updates and necessary engineering studies to advance towards production.

Management of both companies have agreed that under current market conditions and in the interest of the shareholders the consolidation of both entities is the most advantageous strategy for advancing the companies\' gold assets towards production and thus creating value for shareholders.

Exploration activities conducted this summer has been focused on exploration drilling at Oro Gold\'s projects. Four drill rigs are operating with the goal of adding to the already identified resource and targeting new discoveries. An additional drilling program will also be commencing at El Compas shortly.
