VANCOUVER, September 12, 2016 - Luna Gold Corp. (TSX: LGC) ("Luna" or the "Company"), is pleased to announce the results of its pre-feasibility study (PFS) prepared in accordance with National Instrument 43-101 (NI-43-101) on its 100% owned Aurizona gold mine (Project) located in northeastern Brazil. The PFS indicates that the Project represents a robust, rapid pay-back, high margin, simple open pit mining project that demonstrates strong returns in the current gold price environment. The financial results of the study yielded an after-tax internal rate of return (IRR) of 34% and a net present value (NPV) of $201 million based on a base case gold price of $1,250 per ounce and a discount rate of 5% (at $1,350 per ounce gold price the IRR is 41% and the NPV_5% is $256 million).

With the completion of the PFS, Luna has restated its Proven and Probable Mineral Reserves for the mine at 969,000 ounces of gold contained in 18.6 million tonnes of ore at a diluted grade of 1.62 grams per tonne (g/t) of gold. This has been underpinned by the re-evaluation of the Mineral Resources at Aurizona following the comprehensive 2015 drilling program, which included 15,000 metres of oriented core drilling, 3,000 metres of RC drilling and re-logging of historic core. The extensive technical work provides a strong basis for the new project and processing flow sheet to treat all ore types. As a result, the combined Measured and Indicated Mineral Resources are now at 1.6 million ounces of gold (inclusive of reserves) contained in 29.9 million tonnes at a grade of 1.67 g/t gold.

Initial capital expenditure to fund construction and commissioning is estimated at a modest $146 million due to Aurizona's ability to leverage significant existing infrastructure in place at the brownfields mine site. Life of mine (LOM) sustaining capital is estimated to be $47 million. The all-in sustaining cost (AISC) is projected to be an attractive $708 per ounce over the life of the project and the current Mineral Reserves support a 6.5 year mine life with excellent potential to increase the Mineral Reserves and Resources and extend the mine life. Procurement and construction of the new components and equipment for the restart of the mine are expected to take 18 months.

Christian Milau, CEO, stated, "We are very pleased with the results of this pre-feasibility which provides a solid basis for continuing with the development and implementation of the Aurizona Mine restart plan. With so much of the necessary infrastructure already in place, Aurizona compares favourably to its peers given the initial capital is significantly less than many similar size projects. Further, exploration to date has outlined numerous high-priority, near-mine exploration targets that highlight the potential to significantly extend the mine life."

David Laing, COO, added, "This pre-feasibility study is a culmination of the extensive work done thus far to get the Aurizona Mine back into production in the second half of 2018. The 2015 drilling and metallurgical testwork programs have been instrumental in developing a strong technical foundation and have tremendously advanced our understanding of the geology, alteration, weathering, structure and, metallurgy, and their controls on gold mineralization, processing and recoveries."

The Aurizona Mine comprises a brownfield open pit mine, gold processing plant and property containing the Piaba and Boa Esperança gold deposits and numerous exploration targets located in Maranhão State in northeastern Brazil. This PFS provides the compilation of the engineering and geological studies that incorporated the results from the extensive drilling program conducted in 2015.

Notes: This Mineral Reserve estimate has an effective date of June 21, 2016 and is based on the Mineral Resource estimate effective on April 30, 2016. The Mineral Reserve calculation was completed under the supervision of Gordon Zurowski, P.Eng of AGP Mining Consultants Inc., who is a Qualified Person as defined under NI 43-101. Mineral Reserves are stated within the final design pit based on a $1,104 per ounce gold price pit shell with a $1,200 per ounce gold price for revenue. The cutoff grade was 0.38 g/t Au for all pit areas. The mining cost averaged $2.32 per tonne mined, processing averages $11.30 per tonne milled and G&A was $2.84 per tonne milled. The process recovery averaged 90.5%. The exchange rate assumption applied was R$3.50 equal to $1.00. The PFS scope only considers the Piaba and Boa Esperança open pit mineralized zones. The Mineral Resource and Mineral Reserve estimates contained herein may be subject to legal, political, environmental or other risks that could materially affect the potential development of such Mineral Resources.

Mineral resources that are not included within the Mineral Reserves do not have demonstrated economic viability.


Mine

The mine plan is based on the current resource model and calls for conventional truck and excavator/front end loader open pit mine operations with a stripping ratio of 6.2:1. The new mine plan continues mining in the existing Piaba open pit, deepening the pit and mining harder rock types which will be amenable to treatment in the upgraded processing plant following the installation of the new comminution circuit.

The mine plan was developed to provide a practical mining sequence, while optimizing net present value, and incorporates the early mining of the Boa Esperança pit which on completion will provide water storage capacity as part of the overall site water management plan. Primary mining activities will take place in the Piaba pit.

Mining will be performed by a combination of Aurizona owned and operated equipment and a mining contractor. Aurizona performed mining will focus primarily on hard saprolite/transition and fresh rock and will be performed by a combination of hydraulic excavators and front end loaders and 63 tonne rigid frame trucks, and will be responsible for almost all ore mining activities as well as a base load of waste mining. The mining contractor will focus primarily on the laterite and saprolite waste mining, with the exception of the Boa Esperança pit, which will include ore. The overall approach will serve to keep the Aurizona executed mining rate relatively constant while optimizing capital expenditures on mining equipment. Drilling and blasting of all hard saprolite/transition and fresh rock will be performed by Aurizona; explosives will be purchased on a down-hole basis from a local supplier. Hard rock accounts for 57% of the Mineral Reserves, while saprolite and transition account for 14% and 29% respectively. The mine schedule delivers 18.6 Mt of ore grading 1.62 g/t Au to the mill over the Life-of-Mine (LOM). Waste tonnage totalling 115.7 Mt will be stockpiled in the north, west, south and east waste rock management areas. The LOM production schedule is presented in the following table.

Mining costs, including the mining contractor charges, are estimated to average $2.00 per tonne mined (excluding taxes) over the current LOM.

There is excellent potential to extend the mine life beyond the initial approximately seven years through exploration on the Piaba trend.


Process Plant

The PFS is based on a process plant capable of treating 8,000 tonnes per day through a combination of conventional gravity concentration and leach/CIP cyanidation processes. The design includes a new comminution circuit which will treat all ore type which comprises a primary jaw crusher, SAG (semi-autogenous grinding) mill, ball mill and pebble crusher. The plan also calls for the completion of several process items that were partially installed during the Phase 1 Expansion of 2014 as well as the repairs and improvements to the existing process plant equipment. Installations will include an intensive leach reactor, a hybrid leach/CIP circuit, pressurized elution, carbon regeneration kiln, upgraded hydro-cyclones, the addition of three leach tanks, and completion of partly-installed high rate thickeners. Improvements and refurbishments to the existing process plant include upgrades to the cyanide destruct and tailings deposition system, gravity recovery circuit, electrical distribution system, instrumentation and controls and plant infrastructure. The planned daily throughput maximizes the use of power available to the project available on the Maranhão State power grid after certain substation improvements.

Average cost to process a tonne of ore is expected to be $10.96 per tonne milled over the current LOM. The operating cost varies dependent on the blend of the three main ore types being processed. The variations are power and steel consumption, cyanide and lime. The main reasons for the variations are differences in hardness, abrasiveness, mineralogy and alkalinity.


Metallurgy

The Piaba and Boa Esperança ore bodies consist of saprolite, transition and fresh rock mineralization. The average Axb values were moderate for the transition ore and very competent for the fresh rock. The transition ore average Axb (impact breakage test result) value of 67 was the 27th percentile of the Orway Mineral Consultants (OMC) database. The fresh rock average Axb value of 28.1 was the 94th percentile of the OMC database. The Bond ball mill work indices (BWi) values ranged from very soft (saprolite) to moderate (fresh rock). The saprolite, transition and fresh rock average BWi values of 5.7, 8.1, and 13.6 places the respective ore in the 2nd, 7th and 32nd percentile for grinding amenability.

The process gold recovery design criteria are based on test work conducted from 2011 through to 2016. The test work has been consistent across the various campaigns and laboratories and showed that gold is readily recovered using conventional cyanide leaching with a retention time of 30 hours. Utilizing a P80 100 µm grind size, gold recoveries between 90% and 97% are expected over the LOM. Design recoveries by process and metallurgical domain are presented in the table below:


Aurizona Gold Recoveries

Process and Mineralization	Au Recovery
Gravity/Intensive Leach - Piaba Saprolite	21.4%
Gravity/Intensive Leach - Piaba Transition	35.6%
Gravity/Intensive Leach - Piaba Fresh Rock	36.2%
Gravity/Intensive Leach - Boa Esperança Saprolite	19.8%
Gravity/Intensive Leach - Boa Esperança Transition	65.4%
Cyanidation - Piaba Saprolite	72.8%
Cyanidation - Piaba Transition	59.4%
Cyanidation - Piaba Fresh Rock	54.7%
Cyanidation - Boa Esperança Saprolite	73.1%
Cyanidation - Boa Esperança Transition	32.2%
Elution / Carbon Handling / EW - All Ore Types	98.5%
Overall - Piaba Saprolite	93.1%
Overall - Piaba Transition	94.1%
Overall - Piaba Fresh Rock	90.0%
Overall - Boa Esperança Saprolite	91.8%
Overall - Boa Esperança Transition	97.1%

Leaching reagent consumptions ranges from 0.45 to 0.54 kg/t NaCN and 0.80 to 3.71 kg/t CaO.

The orebody is known to contain carbonaceous material which has been tested. The impact on gold recovery is negligible and not considered material. Similarly, the orebody contains small amounts of arsenopyrite, which are considered to have a minor impact on gold recoveries, reducing the LOM recoveries by approximately 2%. Further work is planned to confirm this value.


Tailings Storage Facility

The project will expand the capacity of the existing Vené tailings storage facility (TSF) in three lifts. The first will be carried out before the restart of the process plant, followed by the two additional lifts approximately every two years thereafter. Construction of a new tailings facility, Zé Bolacha, will start in year four. Both facilities are designed as unlined, compacted earth fill structures with sand chimneys and blanket drains. Following cyanide neutralization, tailings slurries (approximately 40% solids) will be pumped via pipeline to the TSF and spigoted from the dam crest to maintain the water pool towards the rear of the reservoir area and away from the main dam embankment. Water will be recovered and pumped back to the process plant or the Boa Esperança pit reservoir.


Infrastructure

Given the brownfields nature of the Aurizona Mine, the project is endowed with considerable infrastructure, which includes the back end of the plant, offices, warehouses, laboratories, communications and camp. It also benefits from the existing road access from Belem (440 km) and São Luis (320 km), as well as the electrical grid via the Maranhão power utility, CEMAR.

The site-wide water balance work has indicated that the operation has access to sufficient fresh water for un-interrupted operations in a variety of conditions, ranging from extreme drought to extreme flooding.


Environmental

The Project has three environmental conditions of note.

Small-scale artisanal operations (garimpos) exist in the region and have impacted the vegetation, the soil and the hydrologic system in areas near the Project. To date, it does not appear that these projects utilize mercury to extract gold as these operations typically utilize hand-held metal detectors.

The mine has excess water during the wet season, and must provide proper sedimentation to all mine runoff and process water prior to discharge in the surrounding estuaries.

In January 2016, mild Acid Rock Drainage (ARD) conditions developed on site, which appear to be related to the oxidation of the exposed transition material. The transition material comprises 16% of the mine waste and is potentially acid generating (PAG). In contrast, fresh waste rock is 22% of waste tonnage and appears to be acid consuming. In order to better mitigate ARD risk, an enhanced static and kinetic geochemical testing program was started, and an ARD management program has been implemented to manage current conditions, along with a LOM mitigation plan.


Labour

There is abundant labour in the region, and as a prior operator, the project has access to previously trained local and regional staff.


Permitting

The Aurizona Mine was placed on care and maintenance in the third quarter of 2015. The Company has worked diligently to maintain its licenses and permits in compliance with regulatory requirements. The Company's team in Brazil is in constant and direct contact with all required regulatory authorities to monitor our licenses and permits. The Company has requested that the existing License to Operate (LO), be amended to cover changes to the operating parameters, including the increased plant throughput to 8,000tpd and raises to the Vené TSF. Receipt of this amendment is anticipated in mid-2017 and is not expected to impact the construction schedule.


Technical Report Preparation

The PFS has been prepared by several independent Qualified Persons (QPs) and was consolidated by Lycopodium Minerals Canada Limited. The Mineral Resources and the new geological block model were prepared by Phoenix Geoscience LLC. The Mineral Reserves, mine plan and mining sections of the study were prepared by AGP Mining Consultants Inc., and the geotechnical and environmental matters were led by Global Resource Engineering Ltd. The financial model and tax analysis was prepared by L&M Assessoria. The Company expects to file a technical report prepared in accordance with NI 43-101 on SEDAR at www.sedar.com within 45 days of the date of this release.


Taxes and Tax Credits

The financial model incorporates recovery of $27 million of certain Brazilian value-added type taxes, primarily ICMS and PIS/COFINS. The financial model also incorporates assumptions about the expansion and extension of income tax deductions made available under a government economic stimulus program (the "SUDENE") to companies for industrial projects developed in northeastern Brazil. The SUDENE deductions total $64 million. The assumed income tax rate is 15.25%


Management Information Systems

The project will benefit from the fully functional mine accounting and management information systems, including warehousing, purchasing and payroll.


Planned Feasibility Study

The PFS recommends that the project continue to the next phase with the preparation of a feasibility study, and contains a number of recommendations including, but not limited to, work programs which address the following areas and continue to de-risk the project:

• Further infill drilling on the Boa Esperança deposit
• Condemnation drilling west and north of the Boa Esperança
• Additional geotechnical field work to support the recommended pit slopes, waste storage facilities, and tailings dam raises
• Additional metallurgical testwork to confirm preliminary indications that the presence of Arsenic does not materially impact gold recovery in the process plant
• Additional geochemical characterization to mitigate ARD risk.
• Other programs associated with site drainage and surface water management.

A $2.4 million program has been outlined by Luna to address these items with the objective of issuing a feasibility study by end of Q1 2017 and targeting first gold pour in the second half of 2018.


Value Enhancement

As the Project continues toward the production phase, all efforts will be expended to identify and quantify ways to enhance project value and reduce costs. These activities will be on-going at all levels of the operation including exploration to determine the optionality of following trends over the brownfields areas contiguous to the Piaba Pit and elsewhere over the Project areas.


Share Consolidation

Luna Gold also announces today a proposed consolidation of its share capital on the basis of up to ten (10) existing common shares for one (1) new common share. Currently, a total of 326,793,355 common shares in the capital of the Company are issued and outstanding. Accordingly, if put into effect on the basis of ten (10) existing common shares for one (1) new common share, a total of 32,679,335 common shares in the capital of the Company would be issued and outstanding following the Share Consolidation, assuming no other change in the issued capital.

The Share Consolidation will affect all of the Company's stock options and warrants issued and outstanding at the effective date. At the time of the Share Consolidation, the number, exchange basis or exercise price of all stock options and warrants issued and outstanding will be adjusted to reflect the ten-for-one Share Consolidation. The actual adjustment will be made by the Company in consultation with its advisors.

These factors include, without limitation, the risks and uncertainties inherent to an economic study such as the PFS, which by nature are subject to numerous uncertainties, the inherent risks involved in the exploration and development of mineral properties, the uncertainties involved in interpreting drill results and other exploration data, the potential for delays in exploration or development activities, the geology, grade and continuity of mineral deposits, the possibility that future exploration, development or mining results will not be consistent with the Company's expectations, accidents, equipment breakdowns, title matters, labor disputes or other unanticipated difficulties with or interruptions in production and operations, fluctuating metal prices, unanticipated costs and expenses, uncertainties relating to the availability and costs of financing needed in the future, the inherent uncertainty of production and cost estimates and the potential for unexpected costs and expenses, commodity price fluctuations, currency fluctuations, regulatory restrictions, including environmental regulatory restrictions and liability, competition, loss of key employees, the risks of operating in a foreign country such as Brazil, the risks inherent to the restart of mining operations, the recovery of value-added type taxes, the expansion and extension of income tax deductions, and other related risks and uncertainties. The Company undertakes no obligation to update forward-looking information except as required by applicable law. Such forward-looking information represents management's and/or its Qualified Persons best judgment based on information currently available. No forward-looking statement can be guaranteed and actual future results may vary materially.

Cautionary Note to U.S. Readers Concerning Estimates of Measured, Indicated and Inferred Mineral Resources

Information concerning the properties and operations discussed in this news release has been prepared in accordance with Canadian standards under applicable Canadian securities laws, and may not be comparable to similar information for United States companies. The terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" used in this news release are Canadian mining terms as defined in accordance with NI 43-101 under guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council on May 10, 2014. While the terms

"Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" are recognized and required by Canadian regulations, they are not defined terms under standards of the United States Securities and Exchange Commission. Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve calculation is made. As such, certain information contained in this news release concerning descriptions of mineralization and resources under Canadian standards is not comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the United States Securities and Exchange Commission. An "Inferred Mineral Resource" has a great amount of uncertainty as to its existence and as to its economic and legal feasibility. It cannot be assumed that all or any part of an "Inferred Mineral Resource" will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. Readers are cautioned not to assume that all or any part of Measured or Indicated Resources will ever be converted into Mineral Reserves. Readers are also cautioned not to assume that all or any part of an "Inferred Mineral Resource" exists, or is economically or legally mineable. In addition, the definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" under CIM standards differ in certain respects from the standards of the United States Securities and Exchange Commission.


Non-GAAP Measures

This release refers to expected EBITDA, cash cost per ounce, AISC per ounce, cost per tonne mined, cost per tonne milled, and certain other non-GAAP measures. These measurements have no standardized meaning under IFRS and may not be comparable to similar measures presented by other companies. These measurements are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

(All amounts in US dollars, unless otherwise indicated)
