Endeavour Silver Corp. provides 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. Endeavour plans to commence development of the Terronera project in Jalisco state and continue with exploration, economic assessment and permitting of the Parral Project in Chihuahua state in 2019. 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; and Silver equivalent Inferred Mineral Resources 82.1 million oz. 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. Excluding the Terronera Mineral Reserves, silver and gold Mineral Reserves at the operating mines increased by 46% and decreased by 2% respectively, notwithstanding significantly reduced Mineral Reserves at El Cubo. 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. Total Inferred silver Mineral Resources increased by 9% due to the success of the 2018 drilling at Parral, where Inferred Mineral Resource Estimates for silver and gold increased 55% and 49% respectively.
