RiverRun Options Aldebaran Mining Project in Brazil

SAO PAULO, BRAZIL--(Marketwire - July 20, 2009) - RiverRun Resources Inc. (PINK SHEETS:RRRO) announces that the company has entered into a Mineral Right Option Agreement to acquire a 100% interest in the exploration and mining rights related to the Aldebaran gold property located in the North Central Amazon Region, Brazil, South America.

The Aldebaran Project is located approximately 540km south of Manaus City and located in the active Tapajos Gold Province which is generally regarded as the largest gold producing district in Brazil. The property is defined by a large gold soil anomaly (in excess of 50 ppb Au) of approximately 30 km2 (6 km x 5 km). The Aldebaran Project has some infrastructure built (camp, airstrip and roads) and is ready to be drilled.

Historical exploration records for Aldebaran show a well mineralized hydrothermal gold system with an indicated size potential of some 300 million tonnes at over 1g/t. Previous drilling has indicate that the high grade sections are predicted to be 2000m in length, 5m thick and 400m deep with grades of 5 g/t. In 2002, Ouro Brasil and Global Consultoria Mineral executed a ground magnetic survey over the soil anomaly delineating a geophysical anomaly over 4 km in length and 800 meters wide.

Under the terms of the Aldebaran option, RiverRun has the exclusive right to a Brazilian mining exploration permit (known as an "EPOA") to explore the mining property. The company may exercise the option to acquire a one hundred percent (100%) undivided interest in the mining rights by making a series of payments over a five (5) year period as follows:

(a) The company has paid US$ 50,000 after execution.

(b) On or before 1st of March, 2010, an amount of US$100,000.

(c) On or before 1st of March, 2011, an amount of US$200,000.

(d) On or before 1st of March, 2012, an amount of US$300,000.

(e) On or before 1st of March, 2013, an amount of US$400,000.

(f) On or before 1st of March, 2014, an amount of US$1,500,000.

If the option payments above and a subsequent decision to mine are made, then a further payment of US$ 2,500,000 is required before the 1st of March 2017 or within 10 business days of reaching an acceptable Banking Feasibility Study. The company must also pay to the Optionor a 1% Net Smelter Return Royalty.

RiverRun President, Mr. Jose Lenzi stated, "We are extremely optimistic about the development opportunity we now have in front of us. Brazil is a pro-mining country offering outstanding mineral resources, commitment to sustained mining development and respect for the environment. The country has well established laws for the management and exploitation of resources and the granting of licenses. The Brazilian geology is endowed with a wide spectrum of metals and minerals which are found in abundance across Brazil's vast territory".

The company has previously focused on its participation (13%) in the Gold Sands Project in Northeastern Peru. Recently, the Board of River Run met to discuss the company's optioned mineral rights in the Peru Gold Sands mining district. Due to the company's challenges with financing its commitment in Peru, RiverRun's Board of Directors has determined to let its Gold Sands Project option lapse and exclusively dedicate the company's resources to the Aldebaran gold project in Brazil.
