• Fiscal 2018 gold production guidance of 110,000 to 120,000 ounces, an increase of 25% over 2017
• COC and AISC of $950-1050 and $1150-1250 respectively a decrease of 10% compared to 2017
• El Valle Transitioning to higher grade oxide mining
• Don Mario transitioning to Cerro Felix by Q3 2018

TORONTO, Sept. 13, 2017 /CNW/ - Orvana Minerals Corp. (TSX:ORV) (the "Company" or "Orvana") is pleased to issue its production, capital expenditure, estimated cash operating costs ("COC") and all-in-sustaining costs ("AISC") guidance for fiscal 2018.

"We are pleased to issue increased production guidance with reduced COC and AISC for fiscal 2018," stated Jim Gilbert, Chairman and CEO. "In keeping with our core strategy and clear commitment to increase production and lower unit costs, our operations have delivered substantially improved results in fiscal 2017 and we expect this positive trend to continue in fiscal 2018. At El Valle, having ramped up development and plant throughput rates, the key objective is to achieve significant grade enhancements by mining a higher proportion of higher gold grade oxide zones. This is expected to result in higher gold production at a slightly lower throughput rate. At Don Mario, production will transition to the Cerro Felix deposit which is the first phase of the anticipated three year mine life extension."

The following tables set out Orvana's fiscal 2018 production, unit cost and capital expenditure guidance. The fiscal 2017 guidance is presented for comparative purposes. The Company remains on track to meet its fiscal 2017 guidance.

El Valle Mine
At El Valle, the Company's flagship asset, the primary objectives in fiscal 2018 are to (i) increase gold production by increasing the proportion of higher gold grade oxide ore processed in the plant; (ii) enhance grade control in the mine by reducing the amount of inferred resources in the mining sequence; and (iii) maintain or improve gold recovery in the plant. These actions are expected to result in increased gold production and a further reduction of COC and AISC in fiscal 2018. Planned capital expenditures at El Valle in fiscal 2018 include underground mine development, completion of infrastructure upgrades, underground fleet upgrades to support oxide mining and a six meter raise of the tailings facility.

Don Mario Mine
During fiscal 2018, the Company will be transitioning its mining activities from the lower mineralized zone ("LMZ") to the Cerro Felix open pit deposit, located approximately 500 meters from LMZ. Development of Cerro Felix is expected to begin immediately in the first quarter with pre-stripping activities, with production expected by the third quarter. The costs of the planned higher strip ratio, in addition to the anticipated lack of recoverable copper from the Cerro Felix deposit are expected to increase unit costs.

The Company is currently investigating the possibility of processing existing stockpiles at Don Mario to produce copper concentrates.  Successful results of the metallurgical and economic evaluations currently being undertaken may allow the Company to blend the resulting material with Cerro Felix feed, which would allow a continuation of concentrate production and copper revenues.

In the event that no blending of copper-bearing stockpile material is possible, concurrent with the commencement of production from Cerro Felix, the Company intends to discontinue the production of copper concentrate and will continue to produce gold doré using its carbon-in-leach circuit. Planned capital expenditures include the tailings storage facility expansion project, which is currently underway, and procurement of additional mining equipment.
