Orosur Mining Inc : Orosur Mining Inc. Receives Water Exploration Permit for Pantanillo Project in Chile

Orosur Mining Inc. (AIM/TSXV: OMI) ("OMI" or "the Company") announces that it has received a water exploration permit from the Chilean Water authority DGA for its Pantanillo Project in Chile. The latest advancement represents a significant development in the overall permitting process for the project.

David Fowler, Chief Executive Officer commented: "We are pleased to announce the granting of a water exploration permit close to the Pantanillo property and the commencement of exploration activities at Pantanillo for 2012. The granting of this water exploration permit represents another vital step towards de-risking the Pantanillo Project."

Pantanillo Water Exploration Permit

In October 2011, OMI signed a contract (the "Contract") with LUMAX S.A. and other two partners to form a consortium (the "Consortium") to explore for water in the Cienaga Redonda basin close to OMI's Pantanillo project. LUMAX S.A. and the partners, companies that are in the lithium mining business had requested water exploration rights over the same area as OMI. According to the Contract, both companies will share water rights equally up to a rate of 120 litres per second. If available water exceeds that number, OMI will retain 60 litres per second. Exploration costs will be split proportional to the amount of water retained by each company. The 60 litres per second flow rate is expected to support a heap leach project of approximately 15 million tonnes per annum.

Following execution of the Contract, the Chilean Government Water Administration granted the Consortium authorization for water exploration on a 4.98 hectare land package in the Cienaga Redonda basin. The authorization is valid for a period of 24 months provided that exploration activities are commenced within the next seven months. Should water exploration yield positive results, the Consortium will have priority to be granted water exploitation rights in the area.

The Consortium has already begun preparing an exploration plan which will be launched in the upcoming months.

Pantanillo 2012 Summer Exploration Campaign

The focus of exploration over the past two years at Pantanillo has been to define a measured and indicated oxide and mixed resource of 45.9 million tonnes of 0.69g/t gold for 1.0 million ounces at Pantanillo Norte.

The primary objective of this summer's exploration campaign commencing in November 2011 will be to test prospective new porphyry target areas aimed at increasing our existing oxide and mixed ore resource. Field work will focus on the Pantanillo Central, Quebrada Pantanillo, Oro 52 and areas surrounding the Pantanillo Norte discovery area. Drilling is expected to commence in January 2012.
