VANCOUVER, British Columbia, Feb. 07, 2018 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (EXK) (TSX:EDR) (NYSE:EXK) reports updated NI 43-101 Mineral Reserve and Resource Estimates for its three operating mines and two development projects and an initial Mineral Resource Estimate for its new Parral Properties, all in Mexico.
2017 Mineral Reserve and Resource Estimate Highlights (Compared to December 31, 2016)
Silver Proven and Probable Mineral Reserves increased 217% to 33.5 million ounces (oz)
Gold Proven and Probable Mineral Reserves increased 246% to 315,300 oz
Silver equivalent Proven and Probable Mineral Reserves increased 228% to 57.1 million oz (75:1 silver:gold ratio)
Silver Measured and Indicated Mineral Resources decreased 46% to 36.7 million oz
Gold Measured and Indicated Mineral Resources decreased 35% to 362,900 oz
Silver equivalent Measured and Indicated Mineral Resources decreased 42% to 63.9 million oz
Silver Inferred Mineral Resources increased 44% to 53.1 million oz
Gold Inferred Mineral Resources decreased 12% to 300,800 oz
Silver equivalent Inferred Mineral Resources increased 22% to 75.7 million oz
Bradford Cooke, CEO of Endeavour, stated, “We enjoyed solid development and exploration success in 2017, more than replacing our Mineral Reserves and growing our silver Mineral Resources. We also published a Pre-Feasibility Study (“PFS”) for Terronera, a Preliminary Economic Assessment (“PEA”) for El Compas, and an initial silver Mineral Resource Estimate for the new Parral Properties. The substantial growth of our Mineral Reserves and Mineral Resources is a testament to our exploration and acquisition teams. We now have a strong pipeline of exploration and development projects to drive our next phase of organic growth.
“Looking forward to 2018, we plan to invest US$11.1 million on exploration, the majority of which will target organic growth opportunities, including brownfields targets around our operating mines and development projects and greenfields targets such as Parral. This year, Parral will be our largest exploration expenditure, as we continue testing new silver vein targets and enhance our geological understanding of the historic Mineral Resource areas. At Terronera, we will test the southeast extension of mineralization in the high grade Terronera Vein and drill other vein targets. At El Compas, further testing of the Misie-Karla-Karla HW and Calicanto Veins and new zones will be key priorities.”
2017 Mineral Reserve and Resource Estimate Summaries
Proven and Probable silver and gold Mineral Reserves increased year over year by 217% and 246% respectively to 33.5 million ounces of silver and 315,000 ounces of gold. On a silver equivalent basis, Mineral Reserves totalled 57.1 million ounces (at a silver to gold ratio of 75:1). These significant increases in Mineral Reserves are mainly due to the reclassification of Mineral Resources into Mineral Reserves pursuant to the NI 43-101 Technical Report, Preliminary Feasibility Study for the Terronera Project, Jalisco State Mexico dated May 18, 2017. The PFS Report estimated 4.06 million tonnes of Probable Mineral Reserves grading 207 g/t silver and 1.95 g/t gold containing 27 million silver ounces and 255,000 gold ounces at Terronera. When the Terronera Mineral Reserves are excluded from the new estimate, silver and gold Mineral Reserves at the three mines decreased by 11% and 9% respectively.
Measured and Indicated silver and gold Mineral Resources declined by 46% and 35% respectively to 31.6 million ounces of silver and 312,600 ounces of gold. The decrease in Measured and Indicated Mineral Resources was mainly the result of conversion into Mineral Reserves at the Terronera project and at the existing operations. When the conversion of Terronera Indicated Mineral Resources to Mineral Reserves are excluded from the Measured and Indicated Mineral Resource Estimate, Measured and Indicated silver and gold Mineral Resources declined 20% and 14%, respectively at the three mines.
Inferred silver Mineral Resources increased by 44% due to the initial Mineral Resource Estimate for the new Parral Properties. At Parral, forty-one drill holes totalling 11,300 metres were completed, primarily to verify a part of the historic Mineral Resource in the Veta Colorada mine area and to test one of the targets within the Palmilla Mine area. The initial estimate consists of an Indicated Mineral Resource of 216,000 silver ounces and an Inferred Mineral Resource of 19.2 million silver ounces and 18,100 gold ounces. A Technical Report prepared in accordance with NI 43-101 for the Parral Properties will be completed and filed on SEDAR in March 2018.
Last year, the Company completed an NI 43-101 Technical Report for a Preliminary Economic Assessment for the El Compas Project, Zacatecas State, Mexico dated May 11, 2017. The Technical Report estimated an initial Mineral Resource of 495,000 silver ounces and 34,900 gold ounces in the Indicated category; and 465,000 silver ounces and 10,600 gold ounces in the Inferred category. The El Compas Mineral Resource is a shallow high grade epithermal vein system that is estimated to provide a robust after tax return on investment (IRR) of 42% (see Endeavour News Release dated March 27, 2017). Due to the positive economics, low initial capital requirements, and management’s experience in having successfully developed similar mines in Mexico, a decision was made to proceed with the mine development in Q3, 2017. The Company expects to reach commercial production at El Compas in July 2018 (see Endeavour News Release dated January 25, 2018).
