Vancouver, Canada – April 3, 2017 – Endeavour Silver Corp. (NYSE: EXK, TSX: EDR) reports updated NI43-101 Mineral Resource and Reserve Estimates and a Pre-Feasibility Study (“PFS”) for its Terronera mine project located 40 kilometres northeast of Puerto Vallarta in the state of Jalisco, Mexico. The PFS will be filed on SEDAR and EDGAR within 45 days of this news release.

The Mineral Resources and Reserves have increased significantly since the Preliminary Economic Assessment was completed in 2015, as outlined below. The main mineralized zone constitutes a shallow, steeply dipping, thick, high-grade portion of the Terronera vein, the development of which should generate reasonably robust economic returns according to the PFS.

Subject to receiving the remaining government mine permits (the MIA or environmental impact statement has already been approved), arranging an appropriate debt financing, and completing certain optimization work on the PFS, management intends to seek approval from the Company’s board of directors to commence development of the Terronera mine and related facilities.

Any decision to advance the Terronera mine into production will be based on the PFS rather than a full Feasibility Study, hence the Company cautions that historically, such projects can have a higher risk of economic or technical failure. The characteristics of the Terronera project are similar to the Company’s other operating mines in Mexico, and management is confident it has sufficient information, experience and expertise to build and operate such a mine.

Bradford Cooke, CEO of Endeavour Silver, commented, “We look forward to getting the green light to develop Terronera into our fifth mine. The main mineralized zone is relatively shallow, steeply dipping, thick and high grade, which at today’s metal prices should generate reasonably robust economic returns. The two-stage development plan starts at 1,000 tpd and expands to 2,000 tpd, which allows us to finance and build a smaller mine, then expand it once the mine is generating positive cash flow. We consider the exploration potential to make new discoveries and expand the resources at Terronera to be very good.

“In 2016, drilling on the Terronera vein expanded the main high-grade, mineralized zone to depth. Surface sampling also located high-grade, silver-gold mineralization in nine other veins on the property. Recently released, very high grade drill results from the La Luz vein confirm the potential for new discoveries. The deep Terronera and shallow La Luz drill results were not included in either the updated Mineral Resource Estimate or the PFS, and they represent one of several opportunities for extending the mine life and optimizing the PFS.”

Mineral Resource and Reserve Estimates

In 2014 and 2015, exploration included 17,500 metres of core drilling at a cost of $4.5 million designed to convert Inferred Resources to Indicated Resources. This drilling activity resulted in an increase of 9.7 million silver ounces (49% increase) and 121,000 gold ounces (78%) in the Indicated Resource category from the May 2015 Preliminary Economic Assessment (PEA). The silver and gold ounces in Inferred Resource category fell 1.4 million ounces and 20,400 ounces respectively from the May 2015 PEA due to the upgrading of Inferred Resources to Indicated Resources.

In 2016, the Company spent $4.1 million on mapping, sampling and drilling at the Terronera project. The Company drilled 18,800 metres and released the positive drill results, which were not included in the updated Resource Estimate or PFS. The updated Terronera Indicated Resource Estimate totals 29.6 million silver ounces and 277,000 gold ounces for 49.0 million silver equivalent ounces (Ag Eq), and the Inferred Resource Estimate totals 7.1 million oz Ag and 34,000 oz Au for 9.5 million oz Ag Eq, as shown in the table below.

Current Probable Mineral Reserves to be mined total 27.0 million oz silver and 255,000 oz gold for 44.9 million oz silver equivalent (Ag Eq) as shown in the table below.

Mine Plan

The mine plan calls for an initial production rate of 1,000 tpd during the first two years of operations, expanding to 2,000 tpd in the third year. The plant will process 4.1 million tonnes over the seven year mine life, grading 207 grams per tonne (gpt) silver and 1.95 gpt gold and recovering 87% of the silver and 75% of the gold. Total life of mine production is expected to be 22.6 million oz silver and 185,000 oz gold for 44.9 million oz Ag Eq, averaging 3.2 million oz silver and 26,400 oz gold or 5.1 million oz Ag Eq per year.

Economic Analysis (all amounts in US dollars)

Initial capital expenditures are estimated to be $69.2 million, comprised of $43.1 million for plant and site infrastructure, $8.7 million for mine development, mine infrastructure and equipment, $9.4 million for owner’s costs, construction camp, and engineering, procurement and construction management (EPCM), and $8.0 million for contingencies.

The capital for the Phase 2 expansion from 1,000 tpd to 2,000 tpd is estimated to be $35.5 million. The expansion consists of $12.0 million to provide sufficient power from the state power grid, $12.0 million for plant expansion, $3.5 million for mine equipment, $2.4 million for owner’s costs, construction camp, and EPCM and $5.6 million in contingencies. An estimated $27.3 million will be required for sustaining capital after commissioning primarily for mine development and tailings expansion. The total Life of Mine (LOM) capital requirements are estimated to be $132.0 million. Management will seek opportunities to optimize the capital requirements going forward.

LOM average operating costs are estimated to be $43 per tonne for mining, $18 per tonne for processing, $7 per tonne for general and administration, and $4 in royalties for a total cost of $72 per tonne. Using Base Case metal prices of $18 per oz silver and $1,260 per oz gold, total cash costs are estimated to be $3.44 per Ag oz net of the gold by-product credit, and all-in-sustaining costs at site are estimated to be $4.76 per Ag oz over the life of the mine. Management also recognizes opportunities to optimize the operating costs going forward.

The mine is expected to generate LOM revenue of $639.5 million, EBITDA of $347.3 million and total free cash flow of $125.3 million. Using a discount rate of 5%, the expected discounted net present value (NPV) is $78.2 million, the expected after tax internal rate of return (IRR) is 21% and payback of capital is 4.3 years, using the Base Case assumptions.
