Endeavour Silver Reports Financial Results for Second Quarter, 2015; LOC Debt Reduced by $4 Million, Cash Holdings Increased by $5.5 Million; Conference Call at 10am PDT (1pm EDT) on August 6, 2015

VANCOUVER, BC--(Marketwired - August 06, 2015) - Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) released today its financial results for the second quarter ended June 30, 2015. 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, 2015 was lower compared to both the First Quarter, 2015 and the Second Quarter, 2014 as a result of lower precious metal prices and lower gold production. Operating costs were slightly higher quarter-on-quarter compared to the First Quarter, 2015 but substantially lower year-on-year compared to the Second Quarter, 2014.

Endeavour CEO Bradford Cooke commented, "Our strong operational and financial performance in the Second Quarter, notwithstanding lower metal prices, allowed us to add $9.5 million in net cash to the balance sheet. We are also on track to meet our production guidance and beat cash cost and AIS cost guidance for 2015.

"Congratulations once again to our El Cubo management and workforce for delivering the 50% El Cubo mine expansion to 2,200 tpd in Q2, 2015 on time and budget! Q3, 2015 should see a decline in operating costs now that the mine expansion is complete. I would also like to recognize the stellar performances of all three of our mine rescue teams in the recent regional competitions in Mexico.

"We released a robust preliminary economic assessment in May for our new, high-grade Terronera mine project in Jalisco state. But with the metal prices still falling in July, management felt it prudent to slow our growth spending at Terronera so the pre-feasibility study has been postponed until January 2016."

Operating Results

Subsequent to Endeavour's news release on July 8, 2015 reporting second quarter production, it was determined that certain work-in-process ounces met the Company's definition of produced ounces, resulting in an additional 35,828 silver ounces and 383 gold ounces produced from the El Cubo mine in the Second Quarter, 2015.

At Guanaceví, quarterly production was higher than planned due to higher than estimated ore grades. In particular, an underground development heading at the Santa Cruz mine extended mineralization into a new, very high-grade area to the southeast and outside of the current resource. Guanaceví production was also above plan at mid-year and is expected to beat annual guidance. Guanaceví placed high in its regional mine rescue competitions and will participate in the Mexican national mine rescue competition. Drill results are expected shortly from the Porvenir Central and Santa Cruz Sur areas.

At Bolañitos, lower quarterly production was planned in the context of the scheduled production ramp-down to 1,000 tpd, only slightly impacted by the previously announced ball mill motor repair in June. Bolañitos production was on plan at mid-year and is expected to meet guidance. Development of and production from the new LL-Asunción vein continues to expand as it replaces ore from the Lucero veins. Bolañitos won second place in first aid and benchman regional mine rescue competitions out of 14 teams. Drill results are expected shortly from the La Joya, San Miguel and Gabriela veins.

At El Cubo, higher quarterly production was planned in the context of the scheduled production ramp-up to 2,200 tpd, which was completed on time and budget by the end of Q2, 2015. El Cubo production was below plan at mid-year but is expected to meet guidance by year-end. El Cubo processed 9,106 tonnes through the Bolañitos plant in June for total plant throughput of 59,667 tonnes in June. Management has initiated a small plant expansion, adding flotation cells and twinning the tailings line at El Cubo to take the plant capacity up to 2,000 tpd by Q4, 2015 for a $400,000 capital investment. El Cubo won first place in the first aid and benchman regional mine rescue competitions, out of 14 teams. El Cubo now moves on to participate in the Mexican national mine rescue competition.

At Terronera, a positive preliminary economic assessment was released in May. The study supports expectations that Terronera can be a profitable silver-gold mine with ample potential for growth of resources, expansion of operations and improvement of the economics. Results were as follows:

• Total pre-production capital expenditures of $65.4 million
• Construction period of approximately 12 months
• Total operating revenue of $542 million from estimated sales of 20.4 million oz of silver and 138,500 oz of gold at $18 per oz silver and $1,260 per oz gold
• Mine-life of 10.3 years
• Total operating costs of $287 million at estimated mine-site cash operating costs of $3.93 per oz silver net of gold credits (silver: gold ratio 70: 1) based on $83 per tonne total operating costs
• Total sustaining capital costs of $75 million, including dry stack tailings and life of mine capital, exploration and G&A expenditures at estimated mine-site AIS costs of $7.60 per oz silver net of gold credits
• Total pre-tax undiscounted cash flow of $115 million
• Pre-tax base-case net present value (NPV) discounted 5% of $74.5 million
• After-tax base-case NPV (5%) of $48.6 million
• After-tax base-case internal rate of return (IRR) of 20.0%
• After-tax base-case pay-back period of 3.7 years

A pre-feasibility study was initiated in January 2015 and advanced as planned to mid-year, including some infill drilling of the inferred resource and additional metallurgical testing to prepare concentrate samples for final flotation results. However, due to the recent drop in precious metal prices, management elected to slow down the pace of PFS expenditures and project permitting at Terronera. Assuming metal prices do not fall further, the PFS is now expected to be completed by January 2016.

Falling precious metal prices have required all three mines to continue focusing on cost reductions and operational efficiencies. This focus and the depreciation of the Mexican peso resulted in operations being ahead of cost guidance for the year. For the six months ended June 30, 2015, cash costs were $8.19 per oz and AIS costs were $15.09 per oz compared to already revised guidance of $9-10 per oz and $16.00-17.50 per oz respectively. Management expects the second half cost metrics to be similar to the first half, putting Endeavour on track to beat its revised cash cost and AIS cost guidance for 2015.

Financial Results

For the second quarter ended June 30, 2015, the Company generated revenue totaling $47.7 million (2014 - $54.8 million). During the quarter, the Company sold 1,912,595 silver oz and 13,797 gold oz at realized prices of $16.34 and $1,191 per oz respectively, compared to sales of 1,774,302 silver oz and 14,612 gold oz at realized prices of $20.10 and $1,308 per oz respectively in Q2, 2014.

After cost of sales of $40.9 million (2014 - $50.4 million), mine operating earnings amounted to $6.8 million (2014 -$4.4 million) from mining and milling operations in Mexico. Excluding depreciation and depletion of $9.4 million (2014 - $14.7 million), and share-based compensation of $0.2 million (2014- $0.2 million), mine operating cash flow before taxes was $16.4 million (2014 - $19.6 million) in Q2, 2015. Net losses were $1.0 million (2014 -$0.3 million) after exploration expense of $2.5 million (2014 - $2.8 million) and corporate general and administrative costs of $2.6 million (2014 - $3.5 million).

The falling Mexican peso and continued focus on cost reductions resulted in lower consolidated operating costs, which fell 20% to $82.80 per tonne in Q2, 2015. This resulted in lower cash costs per oz, net of by-product credits (a non-IFRS measure and a standard of the Silver Institute), which decreased 13% to $8.60 per oz of payable silver compared to $9.87 per oz in Q2, 2014. Similarly the lower operating costs and lower exploration and development expenditures resulted in AIS costs (also a non-IFRS measure) decreasing 18% to $16.86 per oz compared to Q2, 2014. As a result, Endeavour is on track to beat its cash cost and AIS cost guidance for 2015.

Working capital at the end of Q2, 2015 was $26.7 million after using free cash flow to reduce LOC debt by $4 million to $25 million and increase cash holdings by $5.5 million to $31.8 million.
