Orosur Mining Inc (‘OMI’ or the ‘Company’) (TSX: OMI) (AIM: OMI), the South American focused gold producer and explorer, today announces that the development of the Arenal Deeps ramp and lateral waste development to enable production from transverse stopes has been completed. Ore development is underway and stoping is planned to commence by the end of February. Completion of the ramp and lateral development will enable the Company to access higher grade transverse stope ore at Arenal Deeps for the first time in the last quarter of the financial year ending 31 May 2013.

David Fowler, CEO, commented: “I am very pleased to have achieved this important milestone which is a credit to San Gregorio management and employees who have developed the first underground mine in Uruguay over the past two years. This achievement has also importantly been achieved during this fiscal year as San Gregorio has transitioned from contractor development to owner operated development to reduce costs.”
