First Quarter 2016 Highlights:

• Gold production of 132koz, on-track to meet full-year guidance with higher production expected in the upcoming quarters

• All-in Sustaining Cost further decreased to $900/oz ($889/oz excluding Youga which was divested end of February), in line with full-year guidance of $870 to $920/oz

• All-in sustaining margin up 54% over the previous quarter to $37m, lifted by lower AISC/oz and higher gold prices

• Free Cash Flow (before tax, WC & financing costs) of $28m, slightly above guidance

• Net debt reduced to $136m at quarter-end from $259m as of March 31, 2015; and further reduced to $71m following the La Mancha $65m anti-dilution cash injection under the True Gold acquisition‌

George Town, May 2, 2016 - Endeavour Mining (TSX:EDV) (OTCQX:EDVMF) is pleased to announce its financial and operating results for the quarter ended March 31, 2016, with highlights provided in the table below.

Table 1: Key Operational and Financial Highlights

Neil Woodyer, CEO of Endeavour, stated: "Our first quarter results have met our expectations and we are on track to achieve our objectives for 2016. The Agbaou and Ity mines are delivering excellent performance and the underground Tabakoto mines should gain momentum in the coming quarters.

Our group AISC has continued to decrease, achieving $889/oz from our current operations, which provides a solid cash generation foundation. We have also strengthened our financial position with the cash received from La Mancha following the close of the True Gold transaction.

The second quarter will be important for Endeavour with the integration of True Gold's Karma Mine and its ramp-up to commercial production, and the start of construction at our Houndé project which will ultimately become our flagship low-cost mine.

Updated guidance for 2016, which will include these recent developments, will be provided with the release of our second quarter results at the end of July."

 Gold production and AISC on-track to meet full-year guidance

• Endeavour produced a total of 131,567 ounces of gold in the first quarter of 2016 and is on- track to meet its full-year guidance as production is expected to increase in the upcoming quarters with stronger performance expected from the Tabakoto and Nzema mines.

• In line with guidance, All-in Sustaining Costs ("AISC") decreased to $900/oz, down from

  $946/oz during the corresponding quarter of 2015, notably due to the addition of the low-cost Ity mine, and cost reductions at Agbaou and Tabakoto.

• Endeavour's AISC for its continuing operations, which excludes the divested Youga mine, averaged $889/oz during the first quarter of 2016.

Notes: Ity's production and AISC is included for the post-acquisition period beginning November 28, 2015. Youga's production and AISC is included for the pre-sale period ended February 29, 2016. Guidance for 2016 does not include production and costs associated to the Karma mine.

Agbaou Mine

• Agbaou continued its strong performance in Q1-2016, returning to a normal production level after its record production in Q4-2015. Agbaou continues to benefit from mining soft oxide ore leading to robust throughput and recoveries that are expected to continue towards the end of the year.

• The secondary crusher build remains on budget and on time with completion expected in Q3- 2016, which will provide increased flexibility once commissioned.

• Agbaou achieved record low AISC in Q1-2016, mainly due to the renegotiation of mining contract rates following an optimization of the mine plan, and decreased processing costs.

  Tabakoto Mine

• Tabakoto's production remained fairly stable compared to previous quarters despite lower underground grades and volumes achieved as underground extraction was constrained by stope availability.

• Tabakoto's production is expected to improve in the upcoming quarters, lifted by higher grades and volumes as a result of increased stope availability following the underground development completed during the first quarter.

  Ity Mine

• The Ity mine integration progressed well during the first quarter.

• Ity had a strong first quarter performance, with production slightly above guidance and AISC below guidance due to improved cost controls. Ore sourced during the quarter was amenable to high recovery rates and stacking on the leach pads.

  Nzema Mine

• Nzema's production and AISC were negatively impacted by lower volumes of purchased ore, as ore suppliers are ramping-up operations following the halt they experienced in late 2015 due to new permitting requirements imposed on them. As a result, lower grade stockpiles were utilized during the quarter to maintain mill throughput.

• Nzema's performance is expected to improve in the upcoming quarters, as purchased ore tonnage is expected to continue to increase and Endeavour's own grades are expected to improve following completion of the pit cutback during Q4-2016.

  Youga Mine

• On February 29, 2016, Endeavour announced that it had sold its end of life non-core Youga Gold Mine in Burkina Faso for $20 million.

   Increased Cash Flow generation

• All-in sustaining margin increased 54% over the previous quarter to $37 million, lifted by lower AISC/oz and higher gold prices.

• Free Cash Flow (before working capital, tax & financing costs) increased by 133% over the previous quarter to $28 million.

• Notable non-sustaining capital expenditures during the first quarter of 2016 were Agbaou's secondary crusher build and Nzema's push-back, for $3.7 million and $1.7 million, respectively.

• While Endeavour's All-in Sustaining Margin and Free Cash Flow (before working capital, tax & financing costs) improved significantly over the previous quarter, its Q1-2016 free cash flow was impacted by a negative change in working capital, which is expected to return to positive in the upcoming quarters. This working capital movement was mainly due to phasing on accounts payables between Q4-2015 and Q1-2016.

• There were no interest payments made during Q1-2016, as it is payable on a semi-annual basis with the next payments due in June and December.

Table 4: Summarized Cash Flow Statement
