2014 Outlook

The Company's forecast production for the 2014 fiscal year is 50,000 to 55,000 ounces of gold at an average forecasted operating cash cost of US$850 to US$925 per ounce. This represents a reduction of approximately 20% against the US$1,093 per ounce operating cash cost in FY2013. The Directors believe that the cost saving will be achieved by production of higher grade ore from the transverse stopes of Arenal, which commenced at the end of April 2013. Further benefits will accrue from the operational improvement program begun in March 2013. This program is continuing and is expected to generate further improvements in cost savings and overall efficiency in FY2014 and beyond.

Additionally, the Company has elected to reduce the gold price assumptions it uses to optimise its mining plans from US$1,300 to US$1,100 to safeguard the profitability of the reserves from further adverse price changes. The Company is focused on reducing unit operating cash costs while maintaining and extending a mine plan of approximately three years producing 50,000 to 55,000 ounces per year. The operations in Uruguay have maintained a rolling three to five year mine life since inception in 1996. In FY2014, the exploration program will focus on the definition of new resources and reserves near mine and extending the mine life at San Gregorio.

Variations in production and costs may occur each quarter because the mine plan draws ore from several pits at different grades and stages of stripping. The Company is accelerating stope access development for Arenal in the first quarter of FY 2014 and expects to produce some 13,500 to 14,500 ounces in the first quarter. These ounces, as they include development, will have a higher front ended operating cost in the first quarter (US$950 to US$1,000 per ounce) compared to the expected average of US$850-US$925 per ounce for the fiscal year. This is to the benefit of production in the rest of the year with advanced access to the scheduled transverse stoping zones.

Production in 2013

Full year production for the fiscal year ended 31 May 2013 was 64,994 ounces of gold, more than the Company´s guidance of 63,000 ounces for the full year announced on 29 April 2013. This was in the middle of the initial guidance range of 63,000 to 68,000 ounces for the year provided on 14 June, 2012. The production for the year compares with production of 55,458 oz and 55,817 oz in the previous two fiscal years.

The main sources of gold in the fiscal year 2013 were Arenal (33%) where stoping commenced at Arenal Deeps at the end of April, Crucera (20%) and Zapucay (15%). Mill availability reached a new record of 97.31%. Gold recovery increased from 91.8% in the first six months to 94.8% in the second half of the year as a result of optimizing processing procedures and a new strategy of blending ore from various pits.

In Arenal Deeps, ore and waste development during 2013 fiscal year totaled 5,133 metres length. The ramp development was completed in February 2013. During the year the Company made the transition from using a development contractor to performing mine development in-house using Orosur's employees. The contractor workforce was retained by Orosur and a smooth handover was achieved.

Ore production from Arenal was 327,770 tonnes with a grade of 2.19 g/t Au. 126,330 tonnes of ore (39%) was produced from the ramp and the access areas with the balance (61%) coming from the Transverse stoping and Inclined Room and Pillar stopes. The first contribution to mill feed from the Transverse Stopes started at the end of April 2013. The Transverse stopes carry the highest volumes and grade in Arenal. The gold grade in this first stope (4.55 g/t Au) was above management's expectations. The Back-fill raise (226 m long with a diameter of 2.44 m) was finished in April 2013.

The Company is keen to promote a local labour force and has a continuing training program to develop mining skills in Uruguay. Local Uruguayan employees now represent 65% of the total underground workforce.

Cost Control and operational improvement program

The Company has undertaken a significant operational improvement program during the last few months in parallel with its cost reduction efforts. During the first half of the 2013 fiscal year there were significant variances observed between the long term block model and the actual production and between the actual production and the ore control. Both were corrected during the last few months of the fiscal year with the support of expert consultants from Chile and Australia and by the establishment of a strong Mine Geology team. This resulted in improved geological models and ore control practices.

The Company purchased its own small vehicle fleet during FY2013. Over the past years contract mining of satellite pits and ore haulage had become a significant cost item for the Company. Total capital expenditure to acquire this fleet was approximately US$ 4.5m and was funded by a leasing contract with Banco Santander. The amount of material moved by contractors was slowly reduced and their use eliminated by the end of FY2013. The small vehicle fleet is being used to accelerate production in Arenal as well.

The Processing Plant has eliminated one shift of eight hours covering peak electrical power prices (peak prices are about three times standard prices). Despite the elimination of a shift, the plant is scheduled to achieve the production target of 50,000-55,000 ounces of gold for 2014 fiscal year, because of the higher feed grade.

As a consequence of the measures undertaken and the quality of the ore from Arenal, the Company is targeting to reduce its all-in-sustaining costs to approximately US$1,100 per ounce, making the Company well positioned in lower gold price scenarios. The Company continues to strive for further improvements both in the short and long term.

Financial Summary for 2013

Cash operating cost for the year was US$1,093 per ounce of gold compared to US$1,016 for FY2012. This is slightly above the upper limit of the forecast cash costs per ounce, which were increased from US$1,000 to $1,065 on January, 2013. Year on year unit costs have been affected by two opposing factors: whilst total nominal costs increased as a result of cost inflation in Uruguay, which was not offset by an Uruguayan peso depreciation against the US dollar, this loss was mitigated by an improved gold recovery rate from the Arenal Deeps and Crucera, which provided a higher grade of ore.

Cash flow generated by operations before working capital was US$21.2m, for the fiscal year (FY2012: US$22.6m). The average gold price received by the Company was US$1,605 per ounce for the year (FY2012: 1,656 US$/oz).

The Company completed an assessment of the carrying value of its cash generating units (CGUs) as at May 31, 2013, and as a result, recorded a non-cash impairment charge of US$14.1m for property, plant and equipment and development costs. The impairment was driven by a number of factors, including a decline in gold prices and a decline in industry-wide valuations. Additionally, the Company wrote off US$4.2m for exploration properties (Chile: US$0.6m, Uruguay US$3.6m), compared to US$1.2m in FY2012.

The profit before tax and before impairment for the fiscal year was US$2.6m, compared to a profit of US$13.2m in FY2012. The loss after tax and after impairment for the year was US$14.8m compared to a profit of US$1.2m in the prior year.

The Company invested US$22.0m in capital and US$9.2m in exploration for the year compared to US$32.8m and US$17.6m respectively in FY2012.

Orosur's cash position at the end of the year was US$5.6m (FY2012: US$11.5m) with net working capital (current assets less current liabilities including cash) of US$4.3m (FY2012:US$11.0m). The Company has US$ 4.0m of committed but unutilized lines of credit available at 31 May 2013 and it is not planning to use them within the current plans of developments and gold price assumptions.

Capital Expenditure in 2013

Capital expenditure for the year was US$ 22.0m compared to US$ 32.8m in the previous year. Expenditure on Arenal Deeps (US$ 11.4m) was slightly above expectations due to higher than anticipated contractor costs.

Other capital expenditure includes US$ 4.5m relating to the new mining fleet and US$ 2.5m for the second expansion of the tailings storage facilities and the closure of the old tailings dam. The tailings dam construction project was completed on time and within budget.

Exploration and Development in 2013

Chile Anillo - The Company's exploration activities have been focused on the discovery of high grade epithermal (El Peñon-type) gold-silver mineralization in the western part of the property. New data obtained after recent detailed surface mapping suggest the additional possibility of high sulfidation mineralization at Anillo Central area. Surface exploration completed during 2013 showed anomalous gold and silver values. A Controlled Source Audio-Frequency Magneto Tellurics ("CSAMT") survey suggested the presence of silica-bearing structures, which may host economic gold-silver mineralization. Subsequently, a 3,000 metresReverse Circulationdrill program, comprising 10 holes, was carried out, during May and June, 2013.

Results from drilling confirm the existence of gold and silver mineralized quartz structures at Anillo Central. This can be observed at hole AN-13-04RC with a 1.0 m intercept (*) with 490 g/t Ag (≈8.1 g/t Au gold equivalent), at hole AN-13-10RC with a 5 m intercept (*) with 0.46 g/t Au, which includes 1.0 m (*) at 1.1 g/t Au and 11.4 g/t Ag and at hole AN-13-04RC with 1.0 m at 0.34 g/t Au. These results show that the area hosts silica-bearing mineralized structures with encouraging values of Au and Ag. Future work will focus on finding intercepts, grades and continuity of mineralization that may constitute an economic resource for the Company (* apparent width).

A map showing the results from initial drilling at Anillo are accessable at: http://www.orosur.ca/anillo_project

Chile Pantanillo - Orosur's activities have recently been focused on the evaluation of new, potentially higher grade, exploration targets, that lie outside of the existing mineral resource at Pantanillo Norte. The Company has defined at Pantanillo Norte a maiden National Instrument 43-101 measured and indicated mineral resource of 47m tonnes at 0.69 grams of gold per tonne for 1.05 Million ounces of gold.

Recent evidence of a high sulfidation gold system under a steam- heated zone at Quebrada Pantanillo, located approximately 4 kilometres East-Southeast of Pantanillo Norte, and previous interesting Au intercepts at the Oro 52 area, has encouraged the Company to evaluate a further exploration campaign. During FY2013, the Company generated good results from Oro 52 drill campaign: 59 m at 0.48 g/t Au, including 4 m at 1.42 g/t Au and 2 m at 2.94 g/t Au, and 33 m at 0.66 g/t Au, incl 10 m at 1.20 g/t Au (*), (**), (* apparent width) (**intercepts use a cut-off grade of 0.2 g/t and may include up-to 2 meters of waste).

Uruguay Brownfield - The highest priority for exploration and development for the Company is near mine exploration and a study of remnants to add short term production and to extend the life of the San Gregorio mine.

Remnant Sobresaliente - At Sobresaliente, 6 kilometers from the mine, the North zone is in production with good reconciliation given the recent infill campaign which comprised 48 holes for4.477 meters of drilling. Drilling is continuing in the Sobresaliente Central extension and has resulted in good intercepts that are expected to develop a geological model to support the feasibility to proceed to its exploitation during FY2014. This is additional production to the current mine plan. A table of drill results (mineralized intercepts @ 0.5 g/t cut off) at Sobresaliente is accessable at: http://www.orosur.ca/isla_cristalina_belt

Near mine Argentinita - At Argentinita, 29 kilometres from the mine, 75 holes (4,789 metres) were drilled to investigate the potential to increase its resources. The results are very encouraging and show the potential for extensions of the mineralization. More drilling will be required to define additional resources in this zone. The Company is evaluating the underground potential in Argentinita on the basis of these initial results. A table of drill (mineralized intercepts @ 0.5 g/t cut off) at Argentinita is accessable at: http://www.orosur.ca/isla_cristalina_belt

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

Mahoma - 44 drill holes equal to 4,530 meters were completed at the Mahoma project during the first half of 2012/13, approximately 400 kilometres from the San Gregorio mine. This included 1,560 metres of diamond drilling and 2,970 metres of reverse circulation drilling. A Scoping Study was finalized by South American Management S.A. (SAMSA) to update the resource for the Mahoma Project. This considered only the east and west zones of the project, as those are the main mineralized bodies. The South and Central zones were not evaluated. At a 1g/t Au cut-off, the results were a total indicated mineral resource of 162.3 kt @ 1.58 g/t for 8,222 oz Au; with a further 132.9 kt @ 1.61 g/t gold, for 6,861 oz Au in the inferred category. The results obtained did not reflect the expectations raised by the historical data taken on shallower zones. In the lower gold price scenario, Mahoma, located more than 400 km away from the Plant, ranks below the near mine projects in terms of priority, so no additional drilling has been included in the FY2014 and the Resource definition NI 43-101 report has been postponed.

Arenal Deeps - A project for the recovery of pillars in the Arenal Deeps transverse stopes started in May 2013 and is under development by AMEC Consulting. Preliminary results will be available during the second quarter of FY2014. A positive outcome would increase the Arenal resource by about 10,000 to 15,000 oz Au. Any production from these pillars is additional to the Company´s current budget.

Uruguay Greenfield Exploration - Nine projects are under review as part of the Company´s greenfield exploration program in Uruguay. Geological mapping, geophysics, sampling and shallow RAB drilling was carried out in areas with gold mineralization in quartz veins within granitic rock and shear zones in basement rocks. 592 rock and 1098 soil samples were taken and evaluation of these projects is continuing.

Board Changes

As announced on July 12, 2013, the Company appointed three new Directors to the Board of Orosur. John Walmsley (Non-Executive Chairman), Max Oemick and Sergey Kuznetsov (both Non-Executive Directors) joined the Board of the Company. Gustavo Licandro was appointed as interim Chief Financial Officer.

Ignacio Salazar has been confirmed by the Board as Chief Executive Officer with immediate effect.

In the last few months, additional changes to the operations and technical team has further strengthened performance and delivery.

John Walmsley, Non-Executive Chairman, commented: "It has been an eventful yearfor Orosur with major changes in the directorate and management of the Company and a significant reduction in both the current gold price and the price outlook.

Under the circumstances, I am very pleased to be able to report that the programme of vigorous cost cutting and replanning of mining operations, initiated in response to the deteriorating environment, is already beginning to bear fruit. This should bring cash costs down in FY2014 to approximately US$850 - US$925 per ounce and reduce all-in sustaining costs to approximately US$ 1,100 per ounce. Operationally, Orosur will benefit substantially from the recent developments in Arenal , where from the end of April 2013 the mine started to produce from the Transverse stopes where the highest volumes and grades of ore are to be found. This high grade mine is the major asset of the Company and looks set to provide a very attractive source of cash flow into the medium term, particularly in view of the major improvements to extraction techniques.

Ignacio Salazar has been confirmed as CEO of the Company, and the Board would like to commend him for negotiations with the authorities that enabled the Company to make major cost reductions while maintaining good industrial relations and for his leadership in building a first class management team and introducing rigorous planning techniques and controls.

Low and uncertain gold prices remain a concern for all gold miners and Orosur is no exception. However, the Company looks forward to meeting the challenge with a new CEO who has a highly capable and reorganised technical team, supported by a committed and focussed Board of Directors."
