ENDEAVOUR MINING Q2 2015 AISC/OZ OF $898, PROFIT OF $33M AND $20M DEBT PAYMENT IN JULY

Endeavour Mining Corp. had second quarter 2015 gold production of 131,165 ounces, resulting in an all-in sustaining margin of $38.2-million. The AISC (all-in sustaining cost) of $898 per ounce during the second quarter of 2015 demonstrates that the cost-savings trend has continued. Endeavour's operations continue to perform well, and the group is positioned to deliver at the upper end of the gold production guidance of 475,000 to 500,000 ounces and at the low end of the AISC-per-ounce guidance of $930 to $980. For the six-month period, Endeavour has generated $59-million of free cash flow (before tax and financing) to deliver 59 per cent of the $100-million full-year target based on guidance range midpoints.

All amounts are in U.S. dollars unless otherwise indicated.

Second quarter 2015 financial and operating highlights

• Gold production of 131,165 ounces and sales of 129,614 ounces at a realized gold price of $1,193 per ounce;
• Cash cost per ounce sold of $694;
• Operating EBITDA (earnings before interest, taxes, depreciation and amortization) of $53-million;
• AISC per ounce sold of $898;
• AISC margin of $38.2-million;
• At the Tabakoto mine, the AISC per ounce was reduced to $990 and the mine generated a positive AISC margin of $7.7-million in the current quarter;
• Non-sustaining capital investments of $3.8-million;
• After-tax net earnings of $33-million;
• Ended the second quarter of 2015 in a strong financial position, with $52.7-million in cash;
• Based on the strong results in the second quarter of 2015, a $20-million advance principal payment was made in July to further reduce the drawn amount on the revolving credit facility to $260-million.

Neil Woodyer, chief executive officer, stated: "For 2015 we have five key objectives: (1) produce 475,000 to 500,000 ounces; (2) maintain AISC per ounce in the mid-$900s; (3) to be profitable; (4) use free cash flow to reduce debt; [and] (5) extend mine life through exploration success.

"During the second quarter of 2015, we continued to make strong progress on all five objectives. For the six months to June 30, 2015, we have produced 255,000 ounces at an AISC per ounce of $922 and generated net income of $50.5-million.

"We have made a total of $40-million in advance payments so far this year to reduce the drawn balance on the facility to $260-million. It remains our objective to continue reducing our outstanding debt from free cash flow during 2015.

"Our exploration half-year results are in line with our objectives. Most notable is the success of our phase 1 program at Agbaou, which is showing net gains in new oxide mineralization that is now the focus of our phase 2 program."
