recent pressrelease next pressrelease

(PresseBox) - Endeavour Silver Corp. (TSX: EDR, NYSE: EXK - reports updated NI 43-101 Mineral Reserve and Resource Estimates for its operating mines and exploration and development projects in Mexico. Endeavour owns and operates three silver mines in Mexico, the Guanacevi mine in Durango state and the Bolanitos and El Cubo mines in Guanajuato state.

Last year, the Company developed and is now commissioning a fourth mine, El Compas in Zacatecas state.

2018 Mineral Reserve and Resource Highlights (Compared to December 31, 2017)

Silver Proven and Probable Mineral Reserves increased 38% to 46.3 million ounces (oz)

Gold Proven and Probable Mineral Reserves increased 35% to 426,700 oz

Silver equivalent Proven and Probable Mineral Reserves of 80.4 million oz (80:1 silver:gold ratio)

Silver Measured and Indicated Mineral Resources decreased 25% to 27.3 million oz

Gold Measured and Indicated Mineral Resources decreased 20% to 290,400 oz

Silver equivalent Measured and Indicated Mineral Resources of 50.5 million oz

Silver Inferred Mineral Resources increased 9% to 58.0 million oz

Gold Inferred Mineral Resources remained flat at 301,300 oz

Silver equivalent Inferred Mineral Resources 82.1 million oz

Bradford Cooke, CEO of Endeavour, stated, ?We continued to enjoy exploration success in 2018, primarily at Guanacevi, Terronera and Parral. the mine plan, partly offset by reduced Mineral Reserves at El Cubo.

?In 2019, we will once again focus our exploration efforts on growing Mineral Resources and replacing Mineral Reserves at each mine-site as well as expanding Mineral Resources at Parral and other greenfields projects.

Mineral Reserve and Resource Discussion

Proven and Probable silver and gold Mineral Reserves increased year on year by 38% and 35% respectively to 46.3 million oz silver and 426,700 oz gold. On a silver equivalent basis, Mineral Reserves now total 80.4 million oz (at a silver to gold ratio of 80:1). The increased Mineral Reserves are mainly due to in-fill drilling and a robust economic assessment at Terronera, which expanded the Indicated Mineral Resources and converted them to Probable Mineral Reserves, and development of the Milache orebody at Guanacevi, where Indicated Mineral Resources were converted to Probable Mineral Reserves.

Measured and Indicated silver and gold Mineral Resources declined by 25% and 23% respectively to 27.3 million oz silver and 290,400 oz gold. The decrease in Measured and Indicated Mineral Resources was mainly the result of conversion to Mineral Reserves at the existing operations.

Mineral Reserve and Resource Estimates at December 31, 2018(1-16)


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. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.

The Mineral Resources in this estimate were calculated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.

Mineral Resources are exclusive of and in addition to Mineral Reserves.

Guanacevi Mineral Resource and Mineral Reserve cut-off grades are based on a 218 g/t silver equivalent for Santa Cruz Sur of Guanacevi and 222 g/t silver equivalent for Santa Cruz, Porvenir and Milache of Guanacev


El Cubo Mineral Resource and Mineral Reserve cut-off grades are based on a 196 g/t silver equivalent for Area II (that comprises Dolores Mine) of El Cubo and 217 g/t silver equivalent for Areas I&IV (that comprise Santa Cecilia and San Nicolas Mines) of El Cubo. Metallurgical recoveries were 87.0% silver and 86.7% gold for El Cubo.

El Compas Mineral Resource and Mineral Reserve cut-off grades are based on a 3.38 g/t gold equivalent. Metallurgical recoveries were 83.0% silver and 85.0% gold for El Compas

Mineral Resource cut-off grades for Terronera was 150 g/t silver equivalent and the Mineral Reserve cut-off grades for Terronera and La Luz Deposits were 160 g/t and 216 g/t silver equivalent respectively.

Mineral Resource and Mineral Reserve cut-off grades are based on a 150 g/t silver equivalent for Guadalupe y Calvo and Parral Properties.

Mining recoveries of 93% were applied for Guanacev

Dilution factors for Mineral Reserve Estimate calculations averaged 24% for Guanacev Cubo.

Silver equivalent grades are based on a 75:1 silver:gold ratio and calculated including only silver and gold.

Probable Mineral Reserves for Terronera includes the Terronera and La Luz Deposits.

Inferred Mineral Resources for Terronera includes the Terronera, La Luz and Real Alto Area.

Indicated and Inferred Mineral Resources for "Parral (new)" includes the Colorada, Palmilla and San Patricio areas.

The La Colorada structure (Parral) does not contain gold on an economic scale.

Price assumptions for Guanacev

Price assumptions for Terronera are US$17/oz for silver, US$1,275/oz for gold.

Price assumptions for Parral are US$17/oz for silver, US$1,250/oz for gold.

Figures in tables are rounded to reflect estimate precision; small differences generated by rounding are not material to the estimates.

Godfrey Walton, M.Sc., P.Geo., President and COO of Endeavour, is the Qualified Person who reviewed and approved the technical information contained in these Mineral Reserve and Resource Estimates. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All samples are split at the local field office and shipped to ALS-Chemex Labs, where they are dried, crushed, split and 50 gram pulp samples are prepared for analysis. Gold and silver are determined by fire assay with an atomic absorption (AA) finish.

The Mineral Resource Estimates for Terronera, and Parral were undertaken by Independent Qualified Persons Eugene Puritch, P.Eng., FEC, CET, Yungang Wu, P.Geo., and David Burga, P.Geo of P&E Mining Consultants Inc. Mr. Puritch has reviewed and approved the technical content of this press release with respect to the Terronera and new Parral.
