Orosur Mining Inc Announces Grant of Operation Permit for the New Tailings Storage Facility

Orosur Mining Inc

Orosur Mining Inc. (‘OMI’ or ‘the Company’) (TSX: OMI) (AIM: OMI), a South American-focused gold producer and explorer, announces that the Uruguayan National Environmental Agency (DINAMA) has granted on 4 July 2012 the operating license for disposing of tailings at the new Tailings Storage Facility at the San Gregorio mine, Uruguay. The permit has been signed by the Minister of the Environment of Uruguay and is valid for the first phase of tailings disposal.

The new facility has been designed to be built in four phases, each phase requiring continued, staged environmental approval. The granting of staged operating licenses is a result of a recent change on the Uruguayan environmental legislation. The Company does not anticipate that the change in the permitting process will cause any issues for Orosur due to the Company’s historical high standard of operating performance and compliance with environmental regulations.

The construction of phase two of the new storage facility is underway and should be finished in Q3 Fiscal year 2012-2013.

David Fowler, CEO of the Company commented: "We are very pleased that the DINAMA has granted us this new operating license. This license is an important milestone in the continuing operation of San Gregorio and reflects Orosur’s consistently good environmental performance and community engagement."
