TSX:ORV

TORONTO, Dec. 13, 2017 /PRNewswire/ -- Orvana Minerals Corp. (TSX:ORV) (the "Company" or "Orvana") announced today financial and operational results for the fourth quarter ("Q4 2017") and for the fiscal year ended September 30, 2017 ("fiscal 2017). 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 in Bolivia.

The audited consolidated financial statements for fiscal 2017 ("2017 Financials") and Management's Discussion and Analysis related thereto ("2017 MD&A") are available on SEDAR and on the Company's website at www.orvana.com.

Fiscal 2017 Highlights

The Company's strategy to increase production at its operations targets productivity enhancements to allow for delivery of greater throughput, increased gold recovery and reduced unitary costs. The Company is pleased to report the following positive developments in fiscal 2017 as follows:

• El Valle – Transitioning towards increased oxide mining:
• Production from higher gold grade oxide ore at El Valle increased by 69% to 141,164 tonnes in fiscal 2017, compared with fiscal 2017. Total ore mined increased to 733,086 tonnes in fiscal 2017, a 53% year over year improvement.
• As a result of the improvement in mining productivity, allowing for sustained mill throughput rates above 2,000 tonnes per day, gold and copper production increased by 15% and 29%, respectively, compared to fiscal 2016.
• Don Mario – CIL production surpassed targets:
• The re-commissioned carbon-in-leach ("CIL") circuit allowed Don Mario to achieve annual gold production of 38,746 ounces, an 84% increase compared to fiscal 2016 and Don Mario's highest annual gold production since fiscal 2009.
• Gold recoveries from the CIL circuit averaged 87.8% over the second half of fiscal 2017, exceeding the Company's targeted average gold recovery of 80%.
• Realized reductions in unitary costs and improved financial performance:
• Driven by the productivity increases above, consolidated cash operating costs ("COC") fell to $1,015 per ounce, compared with $1,082 per ounce in fiscal 2016 and surpassing 2017 guidance targets of $1,050 to $1,150 per ounce.
• All-in sustaining costs ("AISC") fell to $1,269 per ounce, compared with $1,428 in fiscal 2016 and surpassing 2017 guidance targets of $1,300 to $1,400 per ounce.
• Revenue increased 47% to $138.0 million in fiscal 2017, compared with fiscal 2016; EBITDA improved by $12.1 million to $16.5 million in fiscal 2017.
• Operating cash flow, before working capital changes improved by 129% in fiscal 2017, compared with fiscal 2016, rising to $11.9 million for fiscal 2017.
• Consolidated cash balance increased from $18.9 million at September 30, 2016 to $23.8 million at September 30, 2017.

"We are very proud of our accomplishments in fiscal 2017 at both of our operations, which reflect the effort and commitment of our teams in Spain and Bolivia," stated Jim Gilbert, Chairman and CEO.  "We delivered on our key objectives by meeting production guidance and by lowering COC and AISC to levels that beat our stated cost guidance.  In fiscal 2018, at El Valle, the key objective is to achieve and sustain significant grade improvement by mining a larger proportion of high gold grade oxide zones.  At Don Mario, production will transition to the Cerro Felix deposit which is the first phase of the anticipated three-year mine life extension.  We anticipate that as we work towards meeting these objectives in fiscal 2018, we will realize reductions further in COC and AISC at El Valle that will support our path towards sustained free cash flow and future profitability."

Strategy and Outlook

The Company continues to pursue its initiatives at El Valle and Don Mario on an accelerated basis in order to meet its objectives of optimizing production, lowering unitary cash costs, maximizing fee cash flow, extending the life-of-mine of its operations and growing its operations to deliver shareholder value.

El Valle:

At El Valle, supported by capital infrastructure and development investments, the Company achieved its target of a sustained mill throughput rate of over 2,000 tonnes per day over the second half of fiscal 2017. Increased access to higher gold grade oxide ore fronts at the El Valle Mine and production from the Carlés Mine allowed El Valle to improve its gold production and lower its unitary cash costs progressively over 2017. Objectives in fiscal 2018 include continuing to improve access to oxide ore fronts in the El Valle Mine in order to bring the proportion of oxide ore processed in the plant up to 50%, an increase from historical levels lower than 20%, with the objective of substantially increasing ore grades delivered to the mill. Through additional geotechnical work and infill drilling, the Company also expects to significantly increase the reliability of the mine plan by minimizing the proportion of inferred material in its mine planning in fiscal 2018. Infrastructure investments to improve productivity and efficiency will continue to be made through fiscal 2018 as planned. It is anticipated that these actions will also positively impact El Valle's unitary costs in fiscal 2018.

Don Mario:

At Don Mario, the Company successfully re-commissioned the CIL circuit and completed two full quarters of commercial production of gold doré, increasing gold ounce production to its highest levels since 2009. Gold recoveries exceeded the targeted rate of 80%, reaching an average of 87.8% over the second half of fiscal 2017, up from previous average recoveries of 55% from the flotation process. Don Mario is now pursuing realization of a number of known opportunities for mine life extension. In the near term, the Company expects to commence pre-stripping activities at Cerro Felix in the first quarter of fiscal 2018, and intends to transition its mine production to this satellite deposit following the depletion of the LMZ, expected in mid-fiscal 2018. The Company has been evaluating opportunities to extend the life of Don Mario, including processing existing mineral stockpiles, potential mining of the Company's Las Tojas deposit, and reprocessing gold bearing tailings.

While maintaining its focus on optimizing current operations, the Company will also evaluate strategic alternatives that could serve to transform the profile of the Company.

Cautionary Notes to Investors – Reserve and Resource Estimates

In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates of the Company disclosed in this AIF have been prepared in accordance with NI 43-101 (as defined below), classified in accordance with Canadian Institute of Mining Metallurgy and Petroleum's "CIM Standards on Mineral Resources and Reserves Definitions and Guidelines" (the "CIM Guidelines").

Pursuant to the CIM Guidelines, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with measured or indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, inferred mineral resources may not form the basis of any economic analysis, including any feasibility study. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve, or is or will ever be economically or legally mineable or recovered.
