Orosur Mining Inc. - Fiscal Q2 2016 Results & Operating Update

Orosur Mining Inc. ("Orosur” or the "Company”) (TSX/AIM:OMI), a South American-focused gold producer, developer and explorer is pleased to announce the results for the fiscal 2016’s second quarter ended November 30, 2015 ("Q2 FY16” or the "Quarter”).

As previously announced, during the Quarter the Company implemented a strategic plan to reduce costs in line with the gold price environment post July 2015. Despite Q2 FY16 being a transition quarter, cash operating costs and all-in sustaining costs ("AISC”) for the quarter show a significant improvement from last year and over Q1 FY16. The Company expects that the benefits of the progamme are yet to be fully realized, and shall be more pronounced in Q3 and Q4 FY16.

Highlights

Financial

• Production of 8,172 oz compared with 12,854 oz in Q2 FY15.
• YTD production of 20,643 oz, ahead of the Company’s 30,000 – 35,000 oz guidance for the full year.
• Operating cash costs of US$858/oz, representing a significant improvement over Q2 FY15 (US$984/oz), and also over Q1 FY16 (US$954/oz).
• AISC of US$1,095/oz, representing a significant improvement compared with Q2 FY15 (US$1,258/oz), and also with Q1 FY16 (US$1,166/oz).
• The Company reiterates its stated guidance of AISC below US$1,000/oz as an average for the Q2-Q4 period and between US$1,000-1,100/oz for the full year.
• Average gold price received of US$1,100/oz compared with US$1,212/oz in Q2 FY15.
• Total cash balance of US$2.6M (compared to US$4.8M at May 31, 2015) and debt of US$0.8 million (compared to US$1.5 million at May 31, 2015). The Company has US$3.0M of undrawn lines of credit committed by Banco Santander available at November 30, 2015 and as of the date hereof.
• On December 4, 2015, the President of Uruguay granted Orosur a one-year exemption on the royalty payment to the Government (3% of sales).

Corporate

• As previously announced, the Company has engaged in additional cost-cutting initiatives including
  • Staff levels reduced by more than 40% at the end of the Quarter.
  • Reduction in cash remuneration to the Board of Directors and senior executives as well as the reorganization and streamlining of the Management team.

Operational

• During the Quarter, permitting work continued at the San Gregorio Deeps underground mine project. The main pit was de-watered during the Quarter and the Company is now able to mine approximately 1,500 ounces from the surface of the pit.
• At Arenal Deeps, the Company is testing for the presence of a down-plunge extension/ repetition of the Arenal mineralized structure. During December the drilling started with a plan for a 1,100m diamond drilling campaign between Dec 2015 and Apr 2016.
• At Anillo, Chile, a campaign of 13 reverse circulation ("RC”) drill holes totaling 3,600 metres of drilling was completed on time and on budget on December 9, 2015, testing geologic, geophysical and geochemical indicators of Au-Ag epithermal mineralization at the central-north, northeast, south and west sectors of the project. A meeting of the Technical Committee of Anillo SPA (together with Asset Chile) is planned for February 2016 to review the results and determine the next exploration campaign.
• Following the impairment of the Pantanillo project in May 2015, the Company has decided not to fulfill the payment of advanced royalties totaling US$1.6 million due to Anglo American on December 1, 2015, which triggers a process for the properties to be returned to Anglo American. This will not have any further adverse effect on the balance sheet of the Company.

Ignacio Salazar, CEO of Orosur, said:

"During the Quarter, we implemented a number of substantive internal changes intended to position the Company as a more resilient producer in this current low gold price environment. We are pleased to see the initial reductions in cash operating costs and in AISC already being demonstrated as we remain on track to reducing AISC to below US$1,000/oz for the remainder of the year. These efforts were followed by the decision of the Government of Uruguay to grant a one-year royalty exemption and the decision of the directors and the senior executives to reduce their cash remuneration and the reorganization and streamlining of the management team as already announced. We have been working in many fronts and are encouraged with the smooth progress achieved from these drastic measures.”

Further progress was made as the Company commenced drilling to test a down-plunge extension/ repetition of the Arenal mineralized structure and have de-watered the San Gregorio pit, which is now prepared to commence initial surface mining and development for the undergound project at San Gregorio.

In Chile, drilling at Anillo during the quarter showed overlapping low and high sulphidation epithermal systems. At present, geochemical analysis underway is intended to aid in the preparation of geological models for each system, in order for the Company and Asset Chile to determine the next phase of the exploration program during Q3. The Company decided not to continue to advance the Pantanillo project, given a number of technical difficulties and the level of minimum advance royalties required.

Orosur has a solid portfolio of exploration assets and, in the current environment, our priorities are to advance our projects with near term returns in Uruguay, those of higher quality in Colombia and those which are already financed such as Anillo.”

Q2 FY16 Financial Summary

Gross profit in the Quarter was US$0.04 million compared to a loss of US$1.5 million for Q2 FY15 and a loss of US$0.6 million for Q1 FY16. Lower revenue was offset by lower cost of sales due to the implementation of the strategic cost reduction plan during the quarter.

Cash flow from operations before working capital was US$0.9 million compared to US$0.8 million for Q2 FY15. Net loss after tax was US$0.9 million compared to US$1.2 million in Q2 FY15.

The Company invested US$0.9 million in capital expenditures and US$0.7 million in exploration expenditures compared to US$2.3 million and US$1.1 million respectively in Q2 FY15.

The cash balance at the end of the Quarter was US$2.6 million compared to US$4.6 million at August 31, 2015 and US$4.8 million at May 31, 2015. The Company’s debt balance was US$0.8 million compared to US$1.1 million at August 31, 2015 and US$1.5 million at May 31, 2015. The Company has US$3.0 million of committed but undrawn lines of credit available at November 30, 2015 and as of the date hereof.

Development and Exploration

Uruguay Development Projects

The San Gregorio Deeps underground mine project continued to advance through permitting. A Preliminary Permit was issued by the environmental authority in Q1 FY16 and the Mining Permit is currently in process with the mining authority. The main pit of San Gregorio has been de-watered during the last three months and is now ready for approximately 1,500 ounces to be mined from the pit. Some initial development work is expected to commence shortly to connect the main ramp of open pit mine with the designed portal for San Gregorio Deeps. Based on limited sampling, a portion of the material in this section carries grades between 2 and 5 g/t (Au), mixed with waste material.

A short infill RC drilling campaign of 500 m is underway from the main ramp of the open pit mine with the intention of further defining resources at level 17 of the San Gregorio Deeps project. This work also gives the Company the opportunity to potentially advance mining of a chamber (before developing the ramp from level 32) as well as gaining geological and geotechnical information to optimize the mining design.

At Arenal Deeps, the Company is testing a down-plunge extension/ repetition of the Arenal mineralized structure. By way of background, the Arenal Deeps deposit was initially mined as an open pit, progressing to underground mining more recently. These sorts of deposits are structurally controlled and tend to pinch and swell. A 90 m tunnel has been completed to access and make room for more cost efficient drilling with the aim of testing for a new structure within a distance of 300m from the current underground workings. During December 2015 a 1,100m drilling campaign commenced and is expected to continue through April 2016.

Uruguay Brownfields exploration

Possible extensions of known mineralization have been identified in a number of locations including adjacent to the open pits at Veta Rey, Laureles and Zapucay mines as well as at Rieles which represents the east extension of the San Gregorio Main Pit extending to the East Extension Pit.

The Company is currently focusing its brownfield exploration effort for the remainder of the year in Veta Rey and in the Sobresaliente area. In the Sobresaliente area, the main focus will be on advancing known target zones using NSAMT (Natural Source Audio-frequency Magnetotelluric Imaging) geophysics methods and developing a program of approximately 5,000 meters of Pantera drilling.

Chile

Anillo Project

At Anillo, a campaign of 13 RC holes totaling 3,600 m of drilling was completed on time and on budget on December 9, 2015. Drilling tested geologic, geophysical and geochemical indicators of Au-Ag epithermal mineralization at the central-north, northeast, south and west sectors of the project.

Testing of all drilling intercepts is currently underway to validate assay results and obtain further information on pathfinder geochemical behavior. The results to date demonstrate a non-obvious mixture of low and high sulphidation epithermal, thought to be a result of at least four different magmatic events recognized by geoscientists in the region. Additional geochemistry is expected to aid in the preparation a geological model that interprets the levels of exposure of the dominant mineralization systems in place.

A meeting of the Technical Committee of Anillo SPA (together with Asset Chile) is planned for February 2016 to review the results and determine the next phase of the exploration campaign.

Pantanillo Project

The PEA results of Pantanillo (published June 1, 2012) reached an NPV of US$49.7M at a gold price of US$1,250/oz. At prices below US$1,095/oz, the project has a negative NPV. As a result, and as already announced on August 20^th, 2015, the Company wrote off US$25.5M for exploration properties in the quarter ended May 31, 2015. Consequently, the Company decided not to fulfill the payment of advanced royalties totaling US$1.6 million due to Anglo American on December 1^st 2015, which triggers a process for the properties to be returned to Anglo American. This process will take place over the coming months and it will not have any additional adverse effect on the balance sheet of the Company.

Colombia

As part of the Company’s cost reduction plan, a portion of the Anzá exploration camp has been rented until August 2016 to a major mining company exploring a neighboring district.
