George Town, March 7, 2017 - Endeavour Mining (TSX: EDV ) (OTCQX:EDVMF) is pleased to announce its financial and operating results for the fourth quarter and full year ended December 31, 2016, with highlights provided in the table below.

Table 1: Key Operational and Financial Highlights

1. All financials exclude discontinued Youga operation, except for 2015 production and AISC/oz.
2. Includes Karma's pre-commercial production which started in April 2016. Financial numbers for the pre-commercial production period ending September 30, 2016 don't include Karma's revenue, costs, and operating cash flow is netted against its capital costs.
3. Free Cash Flow Growth Projects stated before WC, tax & financing costs, Houndé and Karma)

Sébastien de Montessus, President & CEO, stated:  "We are proud to have met all of our guidance for the year, achieving record production of 584koz with a significant increase in Q4 compared to Q3, particularly at Agbaou and Tabakoto which increased by 16% and 30% respectively. We are pleased with the continued ramp up at Karma, which has increased production by 43% over the previous quarter to 29koz, while the reserve conversion at the North Kao deposit has extended its mine life beyond 10 years. This strong group performance has allowed us to lower our All-In Sustaining Costs below $900/oz for the first time, and we are on track to continue that momentum in 2017. We have also significantly deleveraged our balance sheet this year, providing strong liquidity and financing sources to fund our organic growth.

Last year's strong performance, which continued in the first quarter, leaves us in a solid position to continue to increase production to 600-640koz and further lower the group's AISC to $860-905/oz in 2017, without the contribution of Houndé for which the construction is progressing on-budget and on-schedule for a first gold pour for Q4.

Looking ahead, we remain focused on unlocking further organic growth potential, with an upcoming investment decision at our Ity CIL development project and through our reinvigorated exploration program."

RECORD HIGH PRODUCTION & RECORD LOW AISC FOR BOTH Q4 AND FY-2016

• As expected, Q4 was Endeavour's strongest quarter with production up 20% over the previous quarter to a record 175koz, and AISC down 5% to record low of $855/oz, as a result of strong increases at Agbaou, Ity and Tabakoto which benefited from the end of the rainy season, and the continued ramp-up at Karma.
• For the full year 2016, Endeavour produced a total of 584koz at a low AISC of $884/oz, achieving both its ambitious production guidance of 575-610koz and its AISC guidance of $870-920/oz.
• Full year 2016 production increased by 13% over 2015, with Agbaou setting another record year and strong contributions from Tabakoto, Ity and Karma, which either met or exceeded their respective guidance while Nzema was impacted by lower than expected purchased ore.
• AISC continued to decrease in 2016 with strong performance at Agbaou and an improved asset portfolio, including a full year's contribution from Ity, the purchase and ramp-up of Karma and the divestment of the higher-cost Youga mine.

AGBAOU MINE

Q4 Insights

• Agbaou achieved a record performance in Q4 as the mine benefitted from the continued high ratio of oxide ore, high recovery rates and the introduction of higher grade transitional ore, which represented 8% of total ore processed during the quarter. AISC decreased mainly due to lower processing costs from the benefit of higher volumes.

Table 4 : Agbaou Performance Indicators

Full Year 2016 Insights

• Full-year 2016 production benefited from higher grades and volumes and continued mill over-performance.

Table 5 : Agbaou Performance Indicators

• The secondary crusher (commissioned in mid-2016 on-time and on budget) provides the flexibility to process higher grade transitional ore while maintaining a fairly constant ore blend and throughput over the remaining life of mine.

2017 Outlook

• After achieving an exceptional year, Agbaou is expected to return to a more normalized and sustainable production rate of 175-180koz in 2017 with fresh ore representing up to 50% of tonnes processed.
• AISC are expected to remain competitive, at $660-700/oz, as higher grade transitional ore is expected to compensate for increased unit costs and lower throughput.

Exploration Activities 

• The drill program commenced later than expected in 2016 due to delays related to land compensation and is therefore now scheduled to be completed in H2-2017.
• The exploration campaign is based on previous geophysics and soil geochemistry results, focusing on the North pit and South pit extensions, the Agbaou South target, Niafouta target, and on generating targets beyond the current resource boundaries.  
• More than 12,900 meters had been drilled by year-end 2016, representing approximately 25% of the exploration program. Results received confirmed mineralization at the Agbaou South and along the Agabou pit extensions.
• An exploration budget of $7 million has been planned for 2017, totaling approximately 45,000 meters of drilling.

Reserve & Resource Evolution 

• As the exploration campaign is still on-going, the change in reserves and resources over the previous year (both down ~175koz) corresponds to depletion and positive reconciliation.
• An update to the reserves and resources will be made following the completion of the exploration program in H2-2017. 

TABAKOTO MINE

Q4 Insights

• Tabakoto achieved a record quarter with production increasing 30% over the previous quarter and AISC falling below $1,000/oz for the first time, due primarily to cost improvement programs, anticipated higher grades from Kofi C and Segala and increased mill throughput following the end of the rainy season.

Table 6 : Tabakoto Performance Indicators

Full-Year 2016 Insights

• Full-year 2016 production benefited from increased overall grade and recovery rates.

Table 7 : Tabakoto Performance Indicators

• An overall improvement of open pit ore tonnes mined was achieved compared to 2015 with an increase of 27% mainly due to opening up and accessing the deeper benches of ore. 
• The underground operations delivered more ore tonnes in 2016 (up roughly 10%) mostly due to an improvement of the reef development and fleet availability. 
• Ongoing cost reduction and optimization programs, which include overhead reductions and a shift to a more local workforce, centralizing procurement, fleet replacement, and improving equipment availability and mining efficiency, have already started to drive costs down further.
• Significant G&A costs per tonne reduction of 18% was achieved due to on-going cost reduction program.

2017 Outlook

• Cost reduction will continue to be the main focus in 2017, with AISC expected to decrease to $950-990/oz.
• Tabakoto production is expected to decrease slightly in 2017 to 150-160koz as grades are expected to slightly decline due to open pit mining transitioning from Kofi C to Kofi B in the second half of the year, and underground mining sequencing.

Exploration Activities 

• Successful exploration grew underground M&I resources by 76koz (inclusive of depletion) and most of the depleted reserves were replaced (down 8koz inclusive of depletion). In addition, underground exploration programs confirmed the discovery of new vein sets that will be delineated in 2017.
• Exploration of the Tabakoto North Open Pit area confirmed the continuation between Tabakoto and Dar Salam, and already added circa 50koz of M&I resources in 2016 with additional drilling to start in Q1-2017 around Kofi C.
• In 2016 the Company discovered the Fougala and Kreko open-pit targets, located less than 7km away from Tabakoto facilities, where delineation is planned in early Q1 2017 with the goal of delivering a new maiden resources by mid-2017.
• As set out in Endeavour's 5-year exploration strategy published in November 2016, Tabakoto is a top exploration priority in 2017 given its relatively short mine life and significant potential. As such, a $9 million exploration program totaling approximately 72,000 meters of drilling has been planned for 2017.
• The 2017 program will focus on both surface exploration, with the aim of delineating resources within trucking distance at discoveries made in 2016 and on new targets, and underground drilling.

Reserve & Resource Evolution 

• Total reserves decreased by 110koz over the previous year, net of depletion, while several new discoveries have been made in 2016, replacing all M&I resources depleted.

ITY MINE

Q4 Insights

• As expected, production increased in Q4 following the end of the rainy season which allowed for increased throughput. In addition, pre-stripping at the Zia pit, positively contributed to Ity's quarter over quarter production increase. The AISC/oz increase over the previous quarter is mainly due to increased G&A seasonal higher spend and higher operating strip ratio.

Table 8 : Ity Performance Indicators

Full-Year 2016 Insights

• Full-year 2016 production remained relatively flat over the previous year as lower grades were offset by increased ore stacked thanks to the availability of new pit material.

Table 9 : Ity Performance Indicators

*For the post Acquisition Period

• Despite the rainy season AISC decreased over the previous quarter due to a lower operating strip ratio and cost reduction programs.
• During the quarter, pre-strip mining began at the Zia pit which began contributing to production in Q4-2016.

2017 Outlook

• Production and AISC are expected to remain stable in 2017 between 75,000 - 80,000 ounces produced with an AISC between $740-780 per ounce.
• The possibility of running the CIL and heap leaching operations in parallel for the first few years is also currently under analysis.  

Exploration and Resource/Reserve Evolution 

• In 2016 the exploration program was focused on drilling previously identified oxide targets to prolong the life of the heap leach operation, and the drilling of new targets with the aim of delineating additional resources for the CIL project.
• Bakatouo and Colline Sud discoveries were announced in 2016 (515koz of M&I resources) with additional infill and extension drilling initiated in Q4-2016. These resources have extended the heap leach mine life by two years (2016 depletion fully replaced + added 78koz) while the remainder is intended for the CIL Project (pending analysis to run both operations in parallel).
• In addition, mineralization was confirmed at several other targets confirmed.
• Drilling started on the Le Plaque target (100% Endeavour owned) in November 2016, with a maiden resource expected in H2-2017.
• The largest portion of Endeavour's 2017 exploration budget has been allocated to the Ity area in light of its strong prospectivity. A $10 million exploration program totaling approximately 50,000 meters is planned for 2017.
• In 2017, exploration will be primarily focused on infill drilling at the Daapleu and Mount Ity deposits, as well as infill drilling and extension drilling at the new Bakatouo and Colline Sud discoveries, on the Le Plaque target and on conducting initial drilling campaigns on strong auger anomalies such as the Yacetouo and Vavoua targets.
• In 2017, an auger drilling program will also be conducted on the 80 km underexplored portion of the Birimian corridor along the Ity trend which was consolidated in September 2016.

Reserve & Resource Evolution 

• Reserves increased by 510koz, net of depletion, due to the publication of the Ity CIL Feasibility Study and conversion of 74koz of Bakatouo and Colline Sud resources to heap leach reserves.
• Despite the addition of 515Koz from the Bakatouo and Colline Sud discoveries, M&I resources decreased by 327koz (net of depletion). This decrease is mainly due to the post-acquisition re-estimation of resources to have a more conservative and robust basis for the Feasibility Study. This re-estimation resulted in a decrease of 0.8Moz of M&I resources, mainly due to the reclassification of 0.6Moz to the Inferred category due to drill spacing confidence.  Infill drilling is underway with the goal of reclassifying a large portion of these resources to the M&I category in 2017, providing additional upside potential for the CIL project.

NZEMA MINE

Q4 Insights

• Production remained flat over the previous quarter as the higher grades mined was offset by lower purchased ore grades.
• The Adamus push-back progressed well over the quarter and is expected to be completed in the first quarter of 2017.

Table 10 : Nzema Performance Indicators

Full-Year 2016 Insights

• 2016 was a transitional year for Nzema as ore feed was constrained to low grade ore mined and stockpiles, supplemented by purchased ore feed.

Table 11 : Nzema Performance Indicators

• The 19% decrease in purchased ore grade and 7% decrease in purchased ore throughput were the key factors contributing to the 20% reduction in gold production compared to the previous year.

2017 Outlook

• Following the cutback, Nzema is expected to generate healthy cash flows for the coming years.
• As a result of the higher expected grades from the Adamus pit following the cut-back, production is expected to increase to 100-110koz in 2017 while AISC are expected to decrease to $895-940/oz.
• To complement production from the Adamus pit, pre-stripping at the Bokrobo deposit is expected to start in the second half of the year.

Exploration Activities

• No significant exploration activity is underway.

Reserve & Resource Evolution 

• Reserves and M&I resources decreased by respectively 65koz and 59koz, due to mine depletion and no exploration activity.

KARMA MINE

Full-Year 2016 Insights

• Commercial production was declared on October 1, 2016. Pre-commercial production revenue and costs have been offset against the mineral interest on the balance sheet.

Table 12 : Karma Performance Indicators

Q4 2016 Insights

• Production continued to ramp up in Q4 to achieve an annualized run-rate of approximately 115koz as the higher grade Rambo pit complemented ore feed from the GG2 pit and stacking capacity continued to improve.

Table 13 : Karma Performance Indicators

• The low AISC of circa $750/oz achieved in Q4-2016, confirms Karma's potential to have low AISC, in line with Endeavour's acquisition case.

2017 Outlook

• Production in 2017 is expected to increase to 100-110koz as higher grade Rambo ore feed will complement that of the GG2 pit with contribution from the Kao pit in the later portion of the year. In addition, stacking capacity is expected to increase in the second half of the year following the completion of the plant optimization efforts.
• AISC are expected to range between $750-800/oz with higher grades and volumes offsetting higher mining cost related to the increased drilling and blasting requirements.
• Capacity at the processing facility is expected to further increase in the second half of the year following changes to the ROM layout, the replacement of the crushing circuit, and other plant optimization activities, which are expected to amount to $27 million. In addition, $8m is being spent to build a 200-Man accommodation facility.

Exploration Activities

• In 2016, the exploration program focused on Kao North infill drilling which confirmed the continuity of the previous inferred resource, and outlined 314koz of M&I resources amenable to heap leach processing (out of a total 456koz added). Subsequently, 262koz were converted to reserves.
• In 2017, a $4 million exploration program totaling approximately 30,000 meters has been planned to drill near-mill targets such as Rambo West and Yabonsgo.

Reserve & Resource Evolution 

• Reserves and M&I resources increased by 167koz and 360koz respectively, net of depletion, as the addition of North Kao extended Karma's mine life to beyond 10 years.

HOUNDE CONSTRUCTION REMAINS ON-TIME AND ON-BUDGET

Construction Achievement To-Date

• Construction is progressing as planned, and is more than 65% complete.
• In 2016, a total of approximately $102 million was spent and a $47 million mining fleet equipment financing agreement with Komatsu was signed. The remaining spend, to be incurred in 2017, is expected to be up to $180 million, as shown below.

• Over 2.7 million man-hours have been worked without a lost-time incident.
• Construction of the 38km long, 91kv overhead power line is more than 60% complete. First power from Sonabel is scheduled for August 2017.
• Open pit pre-strip mining at the Main Vindaloo open pit, adjacent the processing facility, commenced in late 2016.
• Detailed engineering of the processing facility along with the design HAZOP was complete ahead of schedule in November 2016.
• The tailings storage facility is also progressing ahead of schedule and is nearly 60% complete.
• CIL ring beam concrete pour was achieved in early August 2016, and the SAG and Ball Mill first lift on both plinths was completed by year-end.
• The construction of the water harvest dam decant tower is complete, with water already being pumped to the water storage dam two months ahead of schedule.
• Construction of the 300-person permanent accommodation village is nearing completion.
• Over 2,000 personnel including contractors are currently employed on-site, and more than 94% are Burkinabe.
• Construction of the 26Mw backup power station has been awarded. This is on schedule to be operational in Q3-2017.
• The land compensation process has been successfully completed and resettlement commenced in early 2017.

Exploration Activities

• Following a two year period of no drilling exploration, activities will resume in 2017 with a $5 million program totaling approximately 45,000 meters.
• 2017 exploration efforts will leverage the 2016 data analysis, and structural geology and ground geophysical analytical work. The focus will be on delineating high-grade targets such as Bouere and Kari Pump, in addition to preforming reconnaissance drilling.

GROUP RESERVES AND RESOURCES

• Proven and Probable Reserves at year-end 2016 were 7.1Moz on a 100% basis, which increased by 1.2Moz (+19%) compared to 5.9Moz at the end of 2015 mainly due the purchase of Karma and the reserve conversion at its north Kao deposit, the additional reserves at the Ity following the publication of the CIL Feasibility Study and extension of its heap leach operation.
• On a Pro-Forma basis, taking into account for sale of Youga mine and purchase of Karma in 2016, reserves increased by approximately 6% from 6.7Moz to 7.1Moz. Total additions of approximately 0.9Moz offset depletion from mining of approximately 0.6Moz.
• While new discoveries made in 2016 added 1.2Moz of Measured and Indicated Resources ("M&I"), year-end M&I Resources slightly decreased on a Pro-Forma basis from 12.8Moz to 12.6Moz, mainly due to mine depletion and the post-acquisition re-estimation and reclassification of Ity resources (done to have a more conservative basis for the CIL Feasibility Study - infill drilling is currently in progress to reconvert a portion of the resources declassified to inferred status).

INCREASED CASH FLOW GENERATION

• Endeavour generated Free Cash Flow Before Growth Projects (and before working capital, tax and financing costs) of $142 million in 2016, an increase of 55%, which exceeded 2016 guidance.
• Contributing to the increase in free cash flow were higher sales in 2016. This was due to the contribution from Karma effective October 1, 2016, a full year of production from Ity and production improvements at Agbaou and Tabakoto. Stronger production at lower all-in sustaining costs and higher average gold prices in 2016 also had a positive impact on free cash flow.
• Net Free Cash Flow From Operations remained fairly stable over the previous year, at $70 million, as the increase in Free Cash Flow Before Growth Projects was mainly offset by a negative change in working capital, and increased cash settlement and set-up costs of hedging programs.
• Working Capital movements in 2016 was negative $27 million mainly due to inventory, gold-in-circuit and VAT build-up at Karma related to its commissioning phase.
• Cash settlements on hedge programs (related to the legacy gold hedging program for Nzema which was closed out in 2016) amounted to $10 million in 2016 while $5 million cash expense was incurred for the gold collar premium. The remaining gold collar program covers ~187,000 ounces.
• Growth capital of $110 million incurred in 2016 comprised of Houndé construction capital and Ity CIL studies.  
• Restructuring and acquisition costs totaling $24 million was incurred in 2016, comprised of $6 million of acquisition and restructuring costs related to the True Gold transaction, and $18 million of restructuring costs related to ex-CEO and other executive severance packages, and office consolidation.

Table 16: Simplified Cash Flow Statement

SOUND BALANCE SHEET AND STRONG FINANCING & LIQUIDITY SOURCES

• Endeavour significantly improved its balance sheet in 2016, with net debt reduced to $26 million as of December 31, 2016 compared to $144 million at the same date last year, despite roughly $100 million spent on the Houndé project construction. This was due to:
• $185 million of net equity proceeds received since the beginning of the year, which include the La Mancha anti-dilution proceeds related to the True Gold acquisition and the bought deal proceeds.
• $100 million voluntary repayment made under the $350 million revolving corporate facility, resulting in a net drawn amount of $140 million. In addition, the $6 million Auramet loan, previously drawn by True Gold, was also repaid in 2016.
• Endeavour has strong financing and liquidity sources of $334 million which include its $124 million cash position and $210 million undrawn on the revolving credit facility, in addition to its strong cash flow generation.

Table 17: Net Debt Reduction, in US$m

ADJUSTED NET EARNINGS PER SHARE INCREASED BY 143%

• Adjusted earnings attributable to shareholders were $93 million, or $1.15 per share, a 145% increase compared to $0.47 per share in 2015, further illustrating Endeavour's improvement in portfolio quality.
• In 2016, total adjustments of $166 million were made, mainly related to Nzema, as detailed below:

o   $71 million adjustment for an Nzema impairment charge due to the removal of sulfide material from the valuation model as the Company has no plans to invest in its related sulfide mill expansion, in line with management's strategy of focusing efforts on long-life low AISC assets.

o   $45 million add-back of non-cash deferred tax expense, mainly comprised of the de-recognition of historical carry-forward losses at Nzema (shorter life due to removal of sulfide material), the Tabakoto new tax structure decided between Segala and Kofi subsidiaries with the Government, and Accelerated depreciation at Karma utilized in 2016 resulting in a reduced tax base.

o   $24 million of acquisition and restructuring costs, as detailed above.

o   $12 million loss on financial instruments relates primarily to realized and unrealized losses in 2016 on FCFA denominated currency due to the Euro devaluation against the US dollar, while in 2015 the Company realized a gain due to the Euro appreciation.

o   Adjustment for the removal of discontinued Youga operation, as it was sold in 2016.

Table 18:  Net Earnings and adjusted earnings

2017 OUTLOOK: FURTHER PRODUCTION GROWTH AND AISC REDUCTION

• Production is expected to increase to 600,000 - 640,000 ounces (excluding Houndé) in 2017 as improvements at Karma and Nzema are expected to more than compensate for Agbaou returning to a normalized production level after a record-breaking year. As was the case in 2016, production is expected to fluctuate throughout the year due to mine plan sequences, with a peak towards the middle of the year.

Table 19: Production Guidance, koz

• Group AISC is expected to continue to decrease to $860-905/oz due to the full year benefit of Karma, optimizations at Nzema and Tabakoto, and cost reduction programs.  As with production, AISC are expected to fluctuate throughout the year with lower costs expected in the second half.

Table 20: AISC Guidance, $/oz

• Exploration will continue to be an increased focus in 2017 with a company-wide exploration program of roughly $40 million (up approximately 20% over 2016 and more than double that of 2015), totaling 285,000 meters of drilling. Mine related exploration is expected to total $35 million and in addition approximately $5 million has been allocated for grassroots exploration programs.

Table 21: Exploration Guidance, $m

• As detailed in the above mine sections, sustaining and non-sustaining capital allocations for 2017 amount to $65 million and $35 million respectively, in total up approximately $25 million over 2016 due to the addition of Karma. Growth projects amount to $225 million for the Houndé construction, Karma optimization and Ity CIL project.

Table 22: Capital Expenditure Guidance, $m

• Due to the expected increased production and lower AISC, the Free Cash Flow before growth projects (and before working capital movement, tax and financing costs) is projected to increase to circa $150 million, based on the 2016 realized gold price of circa $1,240/oz, and using the mid-point of 2017 production and AISC/oz guidance ranges.
• Based on a more conservative gold price of $1,200/oz, the Free Cash Flow before growth projects (and before working capital movement, tax and financing costs) is projected to be $125 million, with the gold price sensitivity as shown in Table 10 below.

Table 23: Free Cash Flow Guidance based on Production and AISC Guidance Mid-points, $m

• The short-term Gold Revenue Protection Strategy put in place when the Houndé construction was launched in April 2016 will end in June 2017. The remaining gold collar program covers a total of approximately 187,000 ounces, representing approximately 60% of Endeavour's total estimated gold production for the period, with a floor price of $1,200/oz and ceiling price of $1,400/oz.
• As shown in Table 10, within our collar gold price boundaries of $1,200/oz to $1,400/oz, the Free Cash Flow variation to each $100/oz fluctuation is roughly $60 million. Thanks to the Gold Revenue Protection program, if the gold price were to drop below $1,200/oz in 2017, this fluctuation is reduced to roughly $40 million per $100/oz change.

MINERAL RESERVES

1. The following notes apply to all the Resource and Reserve Tables in this AIF the mineral resources and reserves have been estimated and reported in accordance with Canadian National Instrument 43-101, 'Standards of Disclosure for Mineral Projects' and the Definition Standards adopted by CIM Council in May 2014.
2. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
3. All Mineral Resources are reported inclusive of Mineral Reserves
4. Tonnages are rounded to the nearest 1,000 tonnes; gold grades are rounded to two decimal place; ounces are rounded to the nearest 1,000oz. Rounding may result in apparent summation differences between tonnes, grade and contained metal.
5. Tonnes and grade measurements are in metric units; contained gold is in troy ounces.
6. The reporting of Mineral Reserves and Resources are based on a gold price as detailed below:

¹ Cut off grades for all resources open pits are 0,5g/tAu, except at Karma where the cutoff grade is defined by material type: Oxide=0.2, Transition=0.22 and Sulfide=0,5 ² North Kao resources has a gold price of $1,500/oz
