Orosur Mining Inc: Q2 Operations Update

Orosur Mining Inc. (“Orosur” or “the Company”) (TSX/AIM:OMI) a South American-focused gold producer, developer and explorer announces a second quarter (“Q2”) operations update on production from its San Gregorio mine complex in Uruguay.

The Company expects a deferral of approximately 2,000 ounces from Q2 production at the San Gregorio mine complex due to the extended downtime of two long hole drill rigs used in stope production at the San Gregorio Underground West mine (“SGW UG”). Work is well underway to repair the machinery and it is anticipated that the affected drill rigs will return to full productivity by the end of November and the Company has already resumed underground production. During Q2, development continued as planned at SGW UG and mill feed is being partially supplemented by open pit ore and low grade stockpiles causing lower head grades than planned.

Orosur will provide a detailed update on Q2 production in the Quarterly Results Report.
