Endeavour Silver Produces 1,143,788 oz Silver and 13,058 oz Gold (2.1 Million oz Silver Equivalents) in the Second Quarter, 2017

VANCOUVER, BC--(Marketwired - July 12, 2017) - Endeavour Silver Corp. (TSX: EDR) (NYSE: EXK) reports its production results for the Second Quarter, 2017 from the Company's three silver-gold mines in Mexico: the Guanaceví mine in Durango State and the Bolañitos and El Cubo mines in Guanajuato State. Silver production in the Second Quarter, 2017 was 1,143,788 ounces (oz) and gold production was 13,057 oz resulting in silver equivalent production of 2.1 million oz using a 70:1 silver gold ratio.

Production was lower in Q2, 2017 compared to Q2, 2016 due to differences in the annual mine plans. Last year (2016), production was highest in Q1 and lowest in Q4 due to the decision at low metal prices in January 2016 to cut spending on exploration and development at all three mines, which reduced mine access to reserves and therefore reduced metal production.

In 2017, production was higher in Q2 compared to Q1 due to improved performance of the Bolañitos and El Cubo mines. This year, consolidated production should rise from Q1 to Q4 with increased access to reserves due to increased spending on exploration and development at all three mines.

Production Highlights for Second Quarter, 2017 (Compared to Second Quarter, 2016)

• Silver production decreased 26% to 1,143,788 oz
• Gold production decreased 17% to 13,058 oz
• Silver equivalent production was 2.1 million oz (at a 70:1 silver: gold ratio)
• Silver oz sold down 34% to 988,821 oz
• Gold oz sold down 20% to 12,294 oz
• Bullion inventory at quarter-end included 226,437 oz silver and 631 oz gold
• Concentrate inventory at quarter-end included 50,644 oz silver and 890 oz gold

Endeavour CEO Bradford Cooke commented, "Our second quarter production was an improvement over the first quarter thanks to higher tonnes and/or grades from the Bolañitos and El Cubo mines. Both mines are now performing in line with their operating plans for the year. The Guanaceví mine continues to lag behind plan and an internal review has been initiated in order to identify additional actions needed to improve tonnes and/or grades and production.

"We recently made a decision to develop El Compas as our fourth mine and work is now under way on developing the mine ramp to access the orebodies. We also received notice of approval for our mine and plant permits from SEMARNAT last week to build Terronera into our fifth mine. The SEMARNAT and CONAGUA waste dumps and tailings area permits for Terronera are expected later this year."

At Guanaceví, slower mine development due to narrower vein widths than in the resource model resulted in lower mine output than planned, while excess dilution of the ore resulted in lower than planned grades. Management has initiated an internal review of the Guanaceví mine plan and reserve estimate to better understand the variance in production compared to plan in recent months. Over the past year, management has implemented operational changes and made investments to improve the pumping, ventilation and electrical systems at Guanaceví to remediate the operational challenges encountered in the second half of 2016 and first half of 2017.

At Bolañitos, silver grades improved but remained below plan due to grade variations in the LL-Asunción vein. The lower silver grades were offset by higher throughput than planned. Gold production exceeded plan due to higher throughput and gold grades.

At El Cubo, both silver and gold grades were higher than plan, and throughput was slightly below plan. During the quarter, management made changes to both mining methods and ore control processes to reduce the dilution and provide higher-grade material to the plant. Grades are expected to stabilize and throughput should regain plan through year-end.
