Highlights

Financial & Operational Results

• FY17 production of 35,371 oz (within stated guidance of 35-40 koz) following a significant increase in production in Q4 (10,748 oz).
• FY17 Operating cash cost guidance of US$829 (confirmed within stated guidance of US$800 - 900/oz) and representing an improvement on FY16: US$877.
• Average gold price received of US$1,258/oz (FY15: US$1,154/oz).
• Cash flow generated by operations was US$9.7M (FY16: US$7.6M) due to better operating performance and gold price in FY17.
• Profit before tax was US$2.0M (FY16: loss of US$3.2M) due to higher gold price at $1,258/oz (FY16: $1,154/oz) and lower overall costs of sales.
• Successfully built and developed the San Gregorio West underground mine in Uruguay ("SGW UG”) from internally generated funds (total investment in SGW UG during FY17 was US$5.9M).
• The Company invested US$10.8M in capital and US$2.6M in exploration (FY16: US$3.9M and US$2.8M, respectively). In addition to the construction of the SGW UG mine, the Company invested in the completion of the construction of phase 4A of the new tailings dam during FY17.
• All-In-Sustaining Costs ("AISC”) of US$1,228/oz (FY16: US$1,069/oz). The increase was due mainly to the additional development capex associated with building the SGW UG mine.

Exploration and Corporate

• Following completion of the equity raise announced on August 11^th, 2017, the company is in the process of ramping up drilling in Colombia and plans to update the market on recent Exploration progress in both Colombia and Uruguay in short order.

Ignacio Salazar, CEO of Orosur, commented:

"We are very pleased to report a successful FY17 having achieved a number of important corporate milestones whilst simultaneously delivering in line with production and cost targets for the fourth consecutive year.

Cost management and technical excellence remain central to our strategy, demonstrated by successfully building and opening of the second UG mine in Uruguay during the year. The completion of the recent financing announced on August 11^th 2017, which was oversubscribed and at a premium to the prevailing market when negotiated, is an important step to support our growth strategy.

The quality of our assets, our track record on delivery and the recent financing position the Company well for FY18 to make significant progress towards its growth potential and we look forward to reporting results from the resource definition in Colombia, tapping the potential of the highly prospective 100km greenstone belt we control in Uruguay and advancing Anillo in Chile,”

FY18 Outlook & Guidance

The Company expects production from the San Gregorio mine in Uruguay for FY18 to be between 30,000 - 35,000 ounces of gold, with operating costs of US$800 - US$900 per ounce.

At current gold prices this will allow the Company to continue to focus on expanding its resource base in Uruguay both from underground and surface operations, with the aim of increasing its mine life and/or increasing production by utilising the spare capacity in the San Gregorio plant.

As in the past, variations in production and unit costs will occur quarter on quarter as the mine plan draws ore from several sources at varying grades and stages of development or stripping. The Company plans to achieve its production and cost targets over the course of the year.

The Company is preparing to commence a 15,000m drilling campaign in its highly prospective Anzá project in the mid-cauca belt of Colombia. The Company will update the market with drilling results during the year as the program advances.

FY17 Financial Summary

Cash operating costs for the year were $829/oz (FY16: $877/oz), a reduction of 6%, due primarily to lower operating costs related to lower tonnes transported, processed at higher grades during the year and continuous technical improvements and cost management efforts. The Company successfully reached its cash operating cost guidance of US$800 - 900/oz for the year.

All-in-sustaining costs ("AISC”) were $1,228/oz (FY16: $1,069/oz). The increase was due mainly to the additional development capex associated with the SGW UG mine, including ramp, access and ventilation work while at the same time in FY17 the company did not have the benefit of the exemption of the royalty granted for FY16. AISC peaked at $1,345/oz in Q2 17 and since then, the Company started to reduce capital investment during the remainder of FY17.

Cash flow generated by operations before working capital investment was US$9.7M (FY16: US$7.6M) due to better operating performance in FY17 as explained above.

Contribution margin FY17 was US$11.1 (FY16: US$6.8M) and Profit before tax was US$2.0M (FY16: loss of US$3.2M) due to higher gold price at $1,258/oz (FY16: $1,154/oz) and lower costs of sales overall. Net profit after tax for the year was US$2.6M (FY16: loss of US$1.2M).

The Company invested US$10.8M in capital and US$2.6M in exploration (FY16: US$3.9M and US$2.8M, respectively). In addition to the construction of the SGW UG mine, the Company invested during FY17 in completing the construction of the phase 4A of the new tailings dam.

Cash balance at the end of the year was US$3.4M compared to US$4.3M at May 31, 2016. The decrease in cash was mainly due to the development of the SGW UG mine (total investment in SGW UG during the year 2017 was US$5.9M). The SGW UG mine was financed fully from cash from operations. Total debt as at May 31, 2017 was US$0.4M compared to US$0.4M at May 31, 2016. This debt relates to leases on small vehicles and equipment.

The Company has a US$1.5M committed and undrawn line of credit with Banco Santander available as at May 31, 2017, and as of the date hereof.

Exploration Update

Following the equity raise announced on August 11^th, 2017, the company is in the process of ramping up drilling in Colombia and plans to update the market on recent Exploration progress in both Colombia and Uruguay in short order.
