Endeavour Silver Reports Financial Results for Second Quarter, 2017; Updates on Development Projects and 2017 Guidance

VANCOUVER, BC --(Marketwired - August 03, 2017) - Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) released today its financial results for the second quarter ended June 30, 2017. Endeavour owns and operates three underground silver-gold mines in Mexico: the Guanaceví mine in Durango state, and the Bolañitos and El Cubo mines in Guanajuato state.

The Company's financial performance in the Second Quarter, 2017 was impacted by lower production and increased exploration and development activities compared to the Second Quarter, 2016. Production was lower in Q2, 2017 compared to Q2, 2016 due to differences in the annual mine plans. In 2016, production was higher in H1 and declined in H2 whereas in 2017, production should rise incrementally from H1 to H2 with increased access to reserves at all three mines.

Production in the Second Quarter, 2017 was higher than the First Quarter, 2017 due primarily to improved performance of the Bolañitos and El Cubo mines. Both mines are now performing in line with their operating plans for the year whereas Guanacevi continues to lag behind plan. (Click here for an audio review of Q2 highlights).

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. The Guanaceví mine continued to lag behind plan and another internal review was initiated in order to better understand the new issues and possible resolutions.

"At Guanaceví, power outages in the first quarter caused pump failures and some flooding underground. Slower than planned mine development due to narrower vein widths than in the resource model also contributed to lower mine output than planned, while excess dilution of the ore resulted in lower than planned grades. In July, a lightning strike caused a repeat in the electrical issues just as electrical repairs were nearing completion, resulting in another pump failure and renewed flooding in the deeper workings. Recent completion of electrical and ventilation repairs and construction of a new underground pump station should help smooth production in H2, 2017. However, given these setbacks, we have concluded that Guanacevi will not meet its planned production this year and accordingly, we are reducing our consolidated production guidance and raising our consolidated cost guidance.

"We will continue to closely monitor the operating performance at Guanacevi. Returning Guanacevi to long-term profitability relies in part on developing two new orebodies, Milache and Santa Cruz Sur. Underground ramp access is already underway towards Milache and initial production is expected in the second half of 2018. Mine development at Santa Cruz Sur is scheduled to coincide with the development of Milache."

Mine Operations Update

In January, management guided Guanacevi 2017 production to range between 2.4 to 2.6 million silver ounces and 5,300 to 6,300 gold ounces. Due to the narrower vein widths, management now estimates production will range from 800 to 900 tonnes per day, generating 1.0 to 1.1 million silver ounces and 2,100 to 2,200 gold ounces in the second half of 2017. As a result, the revised Guanacevi 2017 full year forecast production is 2.0 to 2.1 million ounces silver and 4,400 to 4,500 ounces gold.

At Bolañitos, silver grades improved during the Second Quarter but were 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. Management expects production on a silver equivalent basis to meet 2017 production guidance.

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 with the completion of a secondary ramp to access better grades. Management expects production on a silver equivalent basis to meet 2017 production guidance.

Development Projects Update

At El Compas, work has begun on installing project infrastructure, collaring the mine access ramp and refurbishing the plant. Project engineering is being refined and optimization studies are underway on mining methods and crushing and grinding alternatives. The Company is waiting for clarification from the state government of Zacatecas regarding an exemption from the new environmental taxes. The explosives permit may take until year-end due to a substantial slowdown in the government permitting process. In the interim, mine development will proceed using a form of low impact gunpowder. Management therefore anticipates an increase in the timeline to production compared to the PEA with mine and plant commissioning now expected to commence in the first quarter, 2018.

At Terronera, work is currently focused on refinement of the project engineering and optimization studies on mining methods, crushing and grinding alternatives and power options. Similar to El Compas, permitting delays have affected the explosives, mine dumps and plant tailings permits so management does not expect to break ground on mine development until the first quarter, 2018, with mine and plant commissioning now anticipated to commence in mid-2019.

Revised 2017 Guidance

Silver production is now expected to be in the range of 4.8-5.2 million oz and gold production is expected be in the 49,100-51,200 oz range. Silver equivalent production is forecast to be 8.5-9.0 million oz using a 75:1 silver:gold ratio, as shown in the table below.

Using the 2017 annual guidance assumptions of $17 per oz silver price, $1,190 per oz gold price, and 20:1 Mexican peso per U.S. dollar exchange rate, cash costs, net of gold by-product credits, are now expected to be $7.00 to $8.00 per oz of silver produced in 2017. Consolidated cash costs on a co-product basis are anticipated to be $10.75 to $11.75 per oz silver and $825 to $900 per oz gold.

All-in sustaining costs of production, net of gold by-product credits in accordance with the World Gold Council standard, are estimated to be $15.25 to $16.25 per oz of silver produced in 2017. When non-cash items such as stock-based compensation are excluded, all-in sustaining costs are estimated to be in the $14.75 to $15.75 range. Direct operating costs are estimated to be in the range of $75 to $80 per tonne. Guanacevi has incurred $10.1 million to date of the annual budgeted $16.7 million in sustaining capital.

Financial Results

For the second quarter ended June 30, 2017, the Company generated revenue totaling $32.7 million (2016 - $44.5 million). During the quarter, the Company sold 988,821 silver oz and 13,058 gold oz at realized prices of $17.16 and $1,270 per oz respectively, compared to sales of 1,493,790 silver oz and 15,364 gold oz at realized prices of $16.54 and $1,289 per oz respectively in Q2, 2016.

After cost of sales of $27.2 million (2016 - $31.6 million), mine operating earnings amounted to $5.4 million (2016 - $12.9 million). Excluding depreciation and depletion of $3.3 million (2016 - $4.1 million), and share-based compensation of $0.1 million (2016- $0.2 million), mine operating cash flow before taxes was $8.8 million (2016 - $17.3 million) in Q2, 2017. Net loss was $16 thousand (2016 - net earnings of $1.7 million) after exploration expense of $3.8 million (2016 - $1.9 million) and corporate general and administrative costs of $2.4 million (2016 - $3.2 million).

Direct production costs per tonne per ounce in Q2, 2017 increased 15% compared with Q2, 2016. Reduced mining activity was offset by cost reductions and the benefits of a lower Mexican peso. Cash costs per ounce rose 56% due to the higher costs per tonne and lower silver grades. All-in sustaining costs rose as a result of management significantly increasing capital investments for the long-term benefit of Guanaceví and El Cubo operations after a two-year period of reduced capital investment to maximize cash flow and ensure the viability of its operations during times of low silver and gold prices.

Working capital dipped to $75.2 million, down 8% from December 31, 2016, more than sufficient for the Company to meet its short and medium term goals.
