2014 Outlook

The Company maintains its FY 2014 production forecast of 50,000 to 55,000 oz of gold at operating cash costs of approximately US$850 to US$925/oz of gold. This is equivalent to a reduction of approximately 20% from the US$1,093 per ounce operating cash costs reported for FY 2013. Should the first quarter trend continue, additional benefits may accrue from operational improvement programmes and may allow Orosur to outperform these forecasts.

Q1 Production and Cash Costs

Production for the Q1 ending 31 August 2013 was 16,851 oz of gold, significantly ahead of the Company’s previous guidance of some 13,500 to 14,500 oz of gold. These ounces were produced at an average cash operating cost of US$ 754/oz, compared to previous guidance of US$950 to US$1,000/oz of gold for the quarter. When compared against the same quarter last year, production is 9% higher and costs 31 % lower (Q1 ‘13: 15,451 oz at cash operating cost of US$1,093/oz).

The increased production and reduced cash costs have been achieved primarily thanks to operational improvements and cost reduction programmes initiated and implemented over recent months. The Company’s focus on refining our geological modelling suite and optimizing ore control processes at the Arenal Deeps underground mine and in the open pits, as well as an overall cost reduction, continued during the quarter, generating further financial and operational improvements.

The Company is optimizing fleet use, improving maintenance and availability and continues to focus on the ongoing productivity of operations. Production of higher grade ore from the tranverse stopes of Arenal Deeps, which commenced at the end of April 2013, resulted in stronger than anticipated production for the quarter, and will be necessary in order for the Company to sustain results of this calibre. Additionally, a stronger than expected US dollar exchange rate (12% appreciation in the quarter) helped mitigate Uruguayan pesos denominated expenditure.

Gold recovery for the quarter was at record highs at 95.7% (compared with 91.7% Q1 ‘13), primarily as a result of the Company’s shift in strategy to feed ore to the plant by source separately. Ore and waste development during the quarter totalled 771 metres length, which is slightly more than anticipated. Ore production from Arenal was 45,550 tonnes at an average grade of 3.66 g/t Au for development and 93,695 tonnes at an average grade of 2.99 g/t Au for stopes. During Q1, Arenal represents 85% of mined ounces and 82% of ounces fed to the mill and plant.

Q1 Financial Summary

The average gold price in the quarter was US$1,321/oz, compared to US$1,598 in Q1 ‘13 (a reduction of US$277). This reduction was offset by a higher reduction, quarter-on-quarter, of US$340 in operating cash costs ($754 vs $1,094) and 1,400 oz of higher production. As a result, the Company generated a Q1 profit before tax of US$1.9M, compared to a Q1 ’13 profit of US$2.5M, with the primary differences including higher depreciation and lower corporate costs. Net loss after tax for the quarter was US$1.0M compared with a net profit US$2.3M in Q1 ’13 due to additional tax credits this year. Cash flow from operations for the quarter was US$6.3M compared to US$5.0M for Q1 ‘13.

The Company invested US$2.5M in capital projects and US$1.5M in exploration for the quarter compared to US$4.7M and US$2.7M respectively in Q1 ’13 as a result of lower expenditures in both the Arenal mine development and the Chilean exploration projects. The company’s cash balance at August 31, 2013 was $6.5M compared with $5.6M at May 31, 2013. The debt balance was reduced in the quarter by $0.5M.

Q1 Exploration and Development

Recovery of Tranverse Stoping Pillars in Arenal Deeps – A study to recover the pillars in the Arenal Deeps transverse stopes commenced in May 2013 and is under development by AMEC Consulting. Preliminary results are anticipated during the Q2 ‘14. A positive outcome would increase the Arenal resource by approximately 10,000 - 15,000 oz Au. Any production from these pillars is additional to the Company´s current budget.

AMEC is expected to finalise the study during Q2, with any recovery from the pillars expected to commence in Q4.

Near Mine and Vaca Muerta Development – At Vaca Muerta, the geological model was re-evaluated and 1,700 metres of infill drilling and exploration have been included in the plan for Q2 ‘14, with the objective of extending the mineralization and re-categorizing resources. The Company aims to exploit Vaca Muerta in the second half of fiscal 2014.

In September 2013, the Uruguayan environmental agency (Dinama) granted the environmental permit for Vaca Muerta. The infill drilling campaign has just started in October 2013 to support metallurgical and geotechnical analysis, and to improve the categorization of resources and reserves. The first drilling of this campaign has thus far verified mineralization, and supported a potential increase in reserves and resources. In parallel with this, the Company is working on improving 20 km of roads, as well as additional logistics and camp facilities.

Uruguay Brownfield and Remnants: Near mine exploration focused during Q1 on the Sobresaliente area and around the San Gregorio operation, where a total of 4,090 metres of RC drilling was conducted in 64 holes at a cost below US$0.3M. As a result, an overall geological resource of approximately 5,500 oz was identified on a preliminary basis (at a cost of approximately ~US$50/oz).

The project portfolio initially included eleven targets, of which five were discarded due to insufficient results and six continue under review. Preliminary geological resources are distributed at Sobresaliente central (67%), Sobresaliente Norte (15%) and Veta Rey (18%). Veta Rey represents an entirely new mineralized structure that was discovered during this period. Initial drilling includes short conventional drill holes and three RC (Reverse Circulation) holes. The mineralization starts from surface and shows good grade consistency along a relatively smooth dipping structure and continues at depth.

Uruguay Satellite Projects

Currently our advanced satellite projects in Uruguay include Laureles and Mina Peru. The Company plans to advance these projects to development in the next six months. During this quarter, the drilling was concentrated on this group of satellite projects completing 2,763.2 out of a total of 3,548.9 metres in 56 holes at a cost of ~ US$ 80 per meter.

Uruguay Greenfield Exploration - Greenfield exploration focused on projects previously ranked as high priority on the basis of resource potential and permit status as the main criteria. In the past eighteen months, the Uruguayan Government has been granting prospecting and exploration permits at a much slower pace than previously; as a result, this has forced Orosur to concentrate on existing permits. At this moment, twelve projects comprise the Company’s exploration portfolio as regards to greenfield and district exploration in Uruguay. Geological mapping, sampling, geophysics, and shallow drilling were carried out in areas with potencial for economic gold mineralization, both in quartz veins within granitic rock as in shear zones in basement rocks.

The Company’s high priority targets are currently Manto Verde, Rincón de los Castillos and Arroyo Laureles. A new drilling rig is being purchased and is expected to arrive during Q3 fiscal 2014 and the bulk of the planned drilling for Uruguay greenfield has therefore been concentrated on the 2^nd half of the fiscal year.

Chile - El Anillo Project – In Chile, the Company concentrated exploration work in this quarter in Anillo, whilst the Pantanillo Project remained closed during the winter season.

Orosur targeted in Anillo high grade epithermal gold-silver mineralization. Activities were concentrated on the central - western part of the property and detailed surface mapping as well as a Controlled Source Audio-Frequency Magneto Tellurics ("CSAMT”) survey suggested the presence of silica-bearing structures which could host economic gold-silver mineralization. On this basis, a 3,000 m RC drill program, comprising 10 holes, was carried out during May and June, 2013. Results confirmed the existence of gold and silver mineralized quartz structures. Mineralized intercepts were obtained at hole AN-13-04RC with a 1.0 metre @ 490 g/t Ag (˜8.1 g/t Au gold equivalent), at hole AN-13-10RC with a 5m intercept (*) @ 0.46 g/t, which includes 1.0 m (*) @ 1.1 g/t Au and 11.4 g/t Ag and at hole AN-13-04RC with 1.0m @ 0.34 g/t Au. Future work will likely focus on finding intercepts, grades and continuity of mineralization that may constitute an economic resource for the Company.

Environment

The President of the Republic of Uruguay recognized the significant contribution of Orosur to the environment and the community in the area around Minas de Corrales in a recent radio programme on 29 August 2013. He used the Company as an example for the development of the incipient Uruguayan mining and exploration industry.

In June 2013, the National Environmental Office conducted the annual general audit. It was concluded that environmental management of mining operation is adequate.

In August 2013, the National Environmental Office granted the Environmental Operation Authorization for Phase 2 of the new Tailings Dam Facility. Monitoring thus far indicates that the new Tailings Dam Facility has operated as planned and no cyanide leaks have occured.

The old Tailings Dam Facility closure activities were planned and executed according to mining equipment availability. It has achieved 85%, 50% and 30% progress in rock, transition material and soil, respectively to date. No unexpected events have occurred and closure is estimated to conclude by December 2013.
