Endeavour Silver Updates Reserves and Resources for Operating Mines
(firmenpresse) - Endeavour Silver Updates Reserves and Resources for Operating Mines
Vancouver, Canada - January 19, 2017 - 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 of December 31, 2016, and restates the 2015 silver and gold resource estimates for its exploration projects. Updated mineral reserve and resource estimates for Endeavours Terronera and El Compas properties will be published in conjunction with their respective economic studies in March, 2017.
Proven and probable silver reserves decreased 12% in 2016 compared to 2015, reflecting mining depletion and reduction in mine development capital investments at the three mines last year due to low metal prices early in the year. Measured and indicated silver resources decreased 2% and inferred silver resources declined 18% due to reduced exploration spending at the operations and dropping the Arroyo Seco project. Exploration programs and budgets were focused on the advancement of the Terronera project, where mineral resources are expected to increase compared to 2015. An initial mineral resource estimate is also being prepared for El Compas in an upcoming preliminary economic assessment.
Bradford Cooke, CEO of Endeavour, stated, The dip in reserves and resources at our three operating mines was a result of our reduced capital and exploration spending last year. Now that metal prices are recovering, we have resumed our investments to find and develop new reserves and resources. Our exploration efforts at the development projects last year were successful in identifying new mineralization, so we anticipate Terronera and El Compas should add to our total resources to be released in March.

1. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that any or all part of the mineral resources will be converted into mineral reserves.
2. Mineral resources are exclusive of and in addition to mineral reserves.
3. Mineral resource and reserve cut-off grades are based on a 198 g/t silver equivalent for Guanaceví, 162 g/t silver equivalent for Bolañitos, 177 g/t silver equivalent for El Cubo, and 100 g/t for Terronera.
4. Metallurgical recoveries were 82.5% silver and 85.4% gold for Guanaceví, 79.6% silver and 84.5% gold for Bolañitos, and 87.8% silver and 84.7% gold for El Cubo.
5. Mining recoveries of 95% were applied for mineral reserve estimate calculations.
6. Minimum mining widths were 0.8 metres for mineral reserve estimate calculations.
7. Dilution factors for mineral reserve estimate calculations averaged 29% for Guanaceví, 21% for Bolañitos, and 30% for El Cubo. Dilution factors are calculated based on internal stope dilution calculations and external dilution factors of 15% for cut and fill mining and 30% for long hole mining.
8. Silver equivalent grades are based on a 75:1 silver:gold ratio.
9. Price assumptions are US$16.29/oz for silver, US$1,195/oz for gold, US$0.82/lb for lead and US$0.90/lb for zinc.
10. Figures in the tables are rounded to reflect estimate precision; small differences generated by rounding are not material to the estimates.
