Orvana Reports 2018 Record Production, Provides Fiscal Year-End Financial Results, Reports 2018 Revised Guidance Met, Provides 2019 Guidance

All Amounts in US Dollars Unless Otherwise Stated

Fiscal 2018 Achievements:

• Record gold production of 103,384 ounces, 14% increase from 90,292 ounces in previous year. Very satisfactory performance was the result of:
• Much improved mining rates for higher-grade oxides ore due to investments in fleet, crews' skills and general underground infrastructure at El Valle; and
• Improved recoveries from the CIL circuit, investment in mining fleet, and full production now underway at new Cerro Felix open pit at Don Mario complex.
• COC and AISC of $1,021 and $1,259, compared to $1,015 and $1,269 for fiscal 2017. Achieved lower range of revised guidance.
• EBITDA of $13.8 million.
• Revenue of $145.8 million.
• Cash balance of $11.6 million as of September 30, 2018.

Fiscal 2019 Outlook:

• At El Valle, continued feed of higher-grade oxides ore processed, to sustain recently achieved gold production levels.
• At Don Mario, steady ore production from Cerro Felix open pit to repeat another positive annual outcome. Also, development of new processing circuit to treat oxides stockpile to extend Don Mario's life of mine by three years.
• Production guidance for fiscal 2019 in line with fiscal 2018 results, plus a welcomed reduction in unitary costs.
• Orvana to continue improving productivity at both operations, while seeking strategic and transformative transactions to enhance profile.
• Renewed regional exploration programs in Spain and Bolivia have potential to increase reserves and resources at local operations.
• Orvana to replace current Samsung C&T Prepayment Facility with a syndicated credit facility from Spanish financial institutions, through its wholly owned subsidiary OroValle. Replacement liability will provide an extended repayment period at a reduced interest rate.

TORONTO, Dec. 21, 2018 /PRNewswire/ -- Orvana Minerals Corp. (TSX:ORV) (the "Company" or "Orvana") announced today financial and operational results for the fourth quarter ("Q4 2018") and for the fiscal year ended September 30, 2018 ("Fiscal 2018). The Company is also providing financial and operational updates for its El Valle and Carlés Mines (collectively, "El Valle") operations in northern Spain and for its Don Mario Mine operations in Bolivia.

The audited consolidated financial statements for Fiscal 2018 ("2018 Financials") and Management's Discussion and Analysis related thereto ("2018 MD&A") are available on SEDAR and on the Company's website at www.orvana.com.  

The Company is pleased to report the following positive developments in Fiscal 2018:

• El Valle – Delivers 13% higher gold production: Oxides ore mining productivity enhancements allowed for 27% higher-grade ore throughput, thus better annual gold output and reduced unitary costs. Mechanical advance rates in oxides areas continued to improve greatly, increasing by 82% to 6,861 metres, versus 3,761 metres in previous year.
• Don Mario – Delivers 16% higher gold production: Open pit mining transitioned from LMZ to Cerro Felix. Mine tonnage increased by 19% to 856K compared to 719K the year before, supported by investment in heavy equipment throughout the year. CIL circuit recovery results exceeded expectations due to better ore quality and process fine tuning by plant's personnel. Better mining tonnage and metallurgical recovery allowed gold production increase to 45K oz, compared to 39K in fiscal 2017. Throughout the year, the Company has been evaluating alternatives to treat its oxides stockpiles. Underway tests show optimal oxides stockpile metallurgy by combining a Sulphidization Acidification Thickening Recycling process ("SART"), with heap leaching, and a Carbon-in-Column (CIC) circuit.

Juan Gavidia, CEO of Orvana Minerals stated: "We have achieved a number of key operational successes that ensure the sustainability of Orvana as a 100,000 oz plus gold producer. Our Spanish and Bolivian teams, supported by prudent capital investments and renewed technical talent, have worked diligently on mining efficiencies to ensure increased production and productivities. Our AISC will continue to be a hard core target in Fiscal 2019, with improvement opportunities expected to come from continued higher-grade ore at El Valle, as well as increased recoveries and operational productivity at both sites."  Mr. Gavidia further stated: "At El Valle, we made excellent strides on mechanical advance, mastering the challenging higher-grade oxides areas. While, at Don Mario, plant recoveries continued to exceed expectations, being at 92% by Fiscal 2018 year-end.  With the transition to Cerro Felix pit now completed, Don Mario unitary costs have stabilized to former lower levels.  Both, El Valle and Don Mario are also enhancing their regional exploration drives to fulfill Orvana's strategic growth."

Strategy and Outlook for Fiscal 2019
The Company continues to pursue its objectives of optimizing production, lowering unitary costs, maximizing free cash flow, and extending life-of-mine of operations while increasing their output.  It continues to seek strategic and transformative transactions to enhance its profile and longevity, including the review of other potential exploration projects, mainly focused in South America, which could be aligned with the Company's strategy of adding to reserves and resources.

At El Valle, the primary objective is to continue increasing higher-grade oxides mining. For that purpose the Company is conducting additional geological and geotechnical work, to increase mining and mine plan reliability.  

At Don Mario, ore will continue to be sourced from Cerro Felix pit and processed at the higher recovery rate achieved the previous year. Next focus is the processing of the oxides stockpile, which will potentially provide a three-year life of mine extension. The metallurgical solution goes through the development of a SART circuit which is in the process of review for engineering and project financing purposes.

New Credit Facility
In August 2016, Orvana entered into a $12.5M copper concentrates and gold doré Prepayment Facility with Samsung C&T. Proceeds of this Facility were used for mine development and infrastructure upgrades at El Valle, both, contributors to present good operational performance. Principal outstanding was $9.118 million at the end of Fiscal 2018.

The Company has been evaluating alternatives to replace the Samsung Facility in order to extend the repayment period and reduce its interest rate. The Company has recently obtained, through its wholly-owned subsidiary OroValle, approval from three Spanish financial institutions to access a syndicated credit facility (the "New Facility") for €6 million.  The closing of the New Facility is subject to the concurrent completion of the early repayment of the Samsung Facility, the release of guarantees and collateral pledged in favour of Samsung, and the execution of applicable legal documentation. The Company has an excellent relationship with Samsung C&T, which has been very cooperative throughout the Prepayment Facility, and looks forward to maintaining this after its replacement.

The New Facility will extend the repayment period from one year (Samsung Facility), to four. The close of the New Facility is expected by early 2019. Once closed, the New Facility will provide the Company with improved financial metrics to fulfill its operational strategy.
