HIGHLIGHTS:

Performance continues to be in line with expectations Gold production of 13,760 oz Q1 – Q3 2015 aggregate production of 40,298 oz On schedule to achieve production towards the top end of FY guidance (50,000 - 55,000 oz) Delivering significant cost reductions US$876/oz operating cash costs, compared to Q1 2015: US$945/oz & Q2 2015: US$984/oz This reduction is in line with the H2 expectations with a return to higher grade mining Company expects further operating cash cost reductions in Q4 2015 YTD operating cash costs of US$934/oz in line with guidance of US$850 - US$950/oz Work is currently underway to commence mining of the Laureles open pit in Q4 2015 with concession and easement approval granted by Uruguayan Minister of Mines during the Quarter Laureles will be the primary source of open pit ore for at least the next half year and the mineralization is open on strike and down dip Completed construction of a further phase of Orosur’ s second tailings dam in San Gregorio on time and within the initial budget and first tailings dam successfully closed. Tailings related expenditures total approximately US$3 million year to date.

During the Quarter gold production from Arenal Deeps accounted for approximately 65% of total production, representing a 20% increase from the previous quarter. The Company expects this figure to increase above 70% during Q4 2015. As per the mine plan, the Company returned to mining higher grade, larger transverse stopes in Q3 2015 and as such expects further reductions in operating cash costs in Q4 2015.

Orosur continues to focus on cost reduction initiatives, including optimizing corporate and operational teams, geological modelling, mine planning, and fleet use.

						H1 Actual			Full yearGuidance			H2 Outlook			Q3 Actual
Gold Produced			Ounces			26,538			50,000-55,000			25,000-30,000			13,760
Cash Operating Cost			US$/oz			964			850-950			850-950			876

Q4 2015 production is expected to be mined primarily from Arenal underground and the new Laureles open pit mine. The Company maintains its production forecast for FY2015 of 50,000 to 55,000 oz of gold at operating cash costs of approximately US$850 -$950/oz of gold. Orosur expects its Q4 2015 results to exceed those in the previous quarters of 2015 due to an increase in ore mined and higher grade from Arenal both driving up production and reducing costs, the commissioning of the Laureles open pit mine and the ceasing of expenditures related to commissioning the new tailings dam.

Laureles Open Pit Mine

During the Quarter, the Minister of Mines signed the Concession and Easement required for Orosur to commence construction and mining at its Laureles open pit mine. Preparatory work at Laureles has since commenced and the Company expects this to be the primary source of open pit ore for the next six months and provide a steady complement to ore from Arenal. Further exploration work is underway at Laureles, as the mineralization is open on strike and down dip.

New Tailings Dam

During the Quarter, closure of the existing tailings dam and construction of phase 2B of the second tailings damn was finalized. This work was completed on time and within the initial budget of approximately US$3 million. The new phase of the tailings dam is designed to provide tailings capacity for at least 18 months.

Ignacio Salazar, CEO of the Orosur commented:

“Orosur has achieved quarterly operating results slightly ahead of our stated guidance and has reduced cash costs by 9% over the first half of our fiscal year, as planned. We continue to demonstrate solid operational performance, and are implementing initiatives to further optimize operations. Operational achievements in this quarter include the successful permitting of the new Laureles open pit mine, closure of the old tailings dam and completion of a new phase in our second tailings dam. In a challenging gold price environment, we are pleased to continue making progress at our operations and anticipate a solid fourth quarter to come. Our intention remains to continue delivering operational improvements both in the short and long term to generate further value for our shareholders.”
