Endeavour Silver Updates Reserve and Resource Estimates, Provides Production and Cost Guidance for 2015; Conference Call at 10:00am PST Today
VANCOUVER, BC--(Marketwired - January 29, 2015) - Endeavour Silver Corp. (TSX: EDR) (NYSE: EXK) reports updated NI 43-101 silver and gold reserve and resource estimates for its three producing mines in Mexico: the Guanaceví Mine in Durango State and the Bolañitos and El Cubo Mines in Guanajuato State; as well as one exploration project, the San Sebastián Project in Jalisco State, as of October 31, 2014.
Endeavour replaced its proven and probable silver reserves in 2014, notwithstanding the shorter estimation period (10 months vs 12 months) and lower metal price assumptions ($18 per ounce (oz) silver vs $22 per oz) compared to 2013. Measured and indicated resources increased in 2014 due to the Company's brownfields exploration programs which upgraded inferred resources primarily at El Cubo and San Sebastián. Inferred resources remained constant for silver and lower for gold year-on-year.
Bradford Cooke, CEO, commented, "Our operations and exploration teams are to be commended for replacing silver reserves and growing our resources in 2014, especially given the lower metal prices and shorter estimation period. This year, we will continue to focus on reserve replacement and as well as mine permitting of the emerging new high-grade Terronera silver-gold vein discovery at San Sebastián."
In past years Endeavour has used the accepted industry practice of three-year trailing averages of silver and gold prices for estimating reserves and resources. At the end of 2014, the trailing price averages were approximately $1,450 per oz gold and $24.72 per oz silver, which management views as too high for use in the estimation of reserves and resources. Instead, management decided to use US$1,260 per oz gold and US$18 per oz silver prices to more reasonably reflect the near-term outlook. The reserves and resources were stress-tested down to $15 per oz silver which resulted in only minor losses, confirming the robustness of our reserves and resources.
2014 Reserve/Resource Highlights (Compared to December 31, 2013)
- Silver Proven and Probable Reserves increased 3% to 12.0 million ounces (oz)
- Gold Proven and Probable Reserves decreased 19% to 113,300 oz
- Silver Equivalent Proven and Probable Reserves totalled 19.9 million oz (70:1 silver:gold ratio)
- Silver Measured and Indicated Resources increased 8% to 65.0 million oz
- Gold Measured and Indicated Resources increased 20% to 665,700 oz
- Silver Equivalent Measured and Indicated Resources totalled 111.6 million oz
- Silver Inferred Resources decreased 1% to 50.7 million oz
- Gold Inferred Resources decreased 23% to 336,900 oz
- Silver Equivalent Inferred Resources totalled 74.2 million oz
- Mineral resources are estimated exclusive of and in addition to mineral reserves
- Proven Reserves are defined within 10 metres of underground development while Probable Reserves extend a further 15 metres from underground development
- 2014 silver equivalents based on 70:1 silver:gold ratio, base metals not included
- All assumptions are listed at the bottom of the reserve and resource summary table
Work on Endeavour's other exploration projects in Mexico (the Guadalupe y Calvo and Parral projects in Chihuahua and the Arroyo Seco project in Michoacán) did not change the resources, and previous estimates remain unchanged. The Guadalupe y Calvo resources were estimated in 2012 and the Parral and Arroyo Seco resources were estimated at the end of 2010.

2015 Production Guidance
As a result of the anticipated decrease in production at the Bolañitos mine in 2015 and the sharp increase in production and reduced unit operating costs at the El Cubo mine in the Q4, 2014, management is currently developing alternative production scenarios for the El Cubo mine, including a possible significant mine expansion to fill available Bolañitos plant capacity in 2015. The Company is seeking the cooperation of the miners' union to accomplish the alternative mine plans in order to ensure the short and long term viability of the El Cubo mining operation. The union recently helped to identify and develop higher grade historic mineralization that facilitated the improved the grades and tonnages in Q4, 2014.
Since the alternative mine plans will not be completed until early March 2015, the Bolañitos and El Cubo mines will continue to produce at close to their respective plant capacities until that time. Based on our review of the alternative mine plans, the following 2015 production guidance may be subject to revision.
Silver production for 2015 is expected to be in the range of 5.8-6.4 million oz, gold production is anticipated to be in the 47,000-52,000 oz range, and silver equivalent production is forecast to be 9.0-10.1 million oz using a 70:1 silver:gold ratio, as shown in the table below.
Mine Ag (M oz) Au (K oz) Ag Eq. (M oz) Tonnes/Day (tpd) Guanaceví 3.1-3.3 6.0-7.0 3.5-3.8 1,200-1,300 Bolañitos 1.2-1.4 22.0-24.0 2.7-3.1 1,100-1,200 El Cubo 1.5-1.7 19.0-21.0 2.8-3.2 1,350-1,450 Total 5.8-6.4 47.0-52.0 9.0-10.1 3,650-3,950 Mr. Cooke added, "We will run the three mines at close to capacity in Q1, 2015 until we complete the alternative mine plans for El Cubo in March. The primary consideration of the alternative mine plans is to reduce unit operating costs at El Cubo. Considering the current low precious metal prices and anticipated lower output from Bolañitos, we plan to produce at a lower rate in 2015 but capital and exploration budgets are significantly reduced this year which should help to boost free cash-flow."
At El Cubo, production will continue primarily from the new V-Asunción, Dolores, Villalpando, San Nicolas and Santa Cecilia veins. At Guanaceví, production will continue primarily from the Porvenir Cuatro, Porvenir Norte, and Santa Cruz deposits. Underground development of the new Santa Cruz Sur and Milache discoveries are awaiting permitting for development in 2015 and production to start in 2016. At Bolañitos, production will continue primarily from the Daniela, Karina, Lana and Bolañitos veins and the new LL-Asunción deposit.
Operating Costs
Consolidated cash costs of production, net of gold by-product credits, are expected to be in the range of $10-11 per oz of silver in 2015. The increase is largely due to the rising contribution of the higher cost El Cubo mine and reduced gold production at the Bolanitos mine. Consolidated cash costs for silver and gold on a co-product basis are anticipated to be around $13-$14 and $900-$950 per oz respectively.
All-in sustaining costs (AISC), net of gold by-product credits, in accordance with the World Gold Council standard, are estimated to be $18-19 per oz of silver in 2015. When non-cash items such as stock based compensation are excluded, AISC, net of gold by-product credits, is forecast in the $17.50-$18.50 range.
On a co-product basis, AISC are predicted to be $18.50-19.50 per oz silver and $1,200-1,250 per oz gold. Direct operating costs are estimated to be in the $90-94 per tonne range.
Capital Budget
Endeavour plans to invest $32.7 million on capital projects in 2015, including $18.3 million on mine development, $11.0 million on plant and equipment, and $3.1 million on tailings upgrades. The mine development capital is for accessing reserves for mining and replacing reserves by converting measured and indicated resources. Endeavour does not estimate reserves based on drill holes, only on underground workings.
The Company has budgeted US$15.0 million at El Cubo, $4.9 million at Bolañitos, $12.5 million at Guanaceví and $0.3 million for corporate items, all of which will be covered by the Company's anticipated 2015 cash flow.
Exploration Expenditures
In 2015, Endeavour plans to spend $6.9 million on exploration, including $0.9 million required for property payments. A total of 26,000 metres of drilling in approximately 150 holes are budgeted to test multiple exploration targets in addition to the underground mine exploration drilling.
The Company will focus on brownfields exploration around the three operating mines in order to replenish resources as well as infill and condemnation drilling needed for engineering the emerging new high grade silver-gold discovery in the Terronera vein on the San Sebastián property in Jalisco State.
