Endeavour Silver Drill Programs Discover New High-Grade, Silver-Gold Mineralized Zones at the El Compas and Terronera Properties in Mexico

Share article on

Vancouver, Canada – December 13, 2016 - Endeavour Silver Corp. (NYSE: EXK, TSX: EDR - https://www.youtube.com/watch?v=fUuV1LadgGI&t=2s ) announces that exploration drill programs on the El Compas property in Zacatecas State and the Terronera property in Jalisco State, Mexico have discovered new high-grade, silver-gold mineralized zones within recently identified epithermal quartz veins on each property. 

These two drill programs are being conducted as part of two ongoing economic studies, a preliminary economic assessment (PEA) for El Compas and a pre-feasibility study (PFS) for Terronera, to evaluate the potential for advancing each of these two development projects to production. 

El Compas

At El Compas, two previously explored veins, El Compas and El Orito, contain small but high-grade, historic resources estimated in January 2016 by the previous owner. Endeavour has not yet completed sufficient work to verify the historic resource, and is not relying on it. Recent drilling in the Ana Camila vein, a splay of the El Orito vein located about 550 metres (m) southeast of El Orito, has outlined a new high-grade, south plunging mineralized zone over 250 m long by 100 m deep, starting approximately 100 m below surface and still open to surface and at depth (view long section here).

Recent drilling highlights are summarized in the table below and include 72 grams per tonne (gpt) silver and 26.5 gpt gold (1,928 gpt silver equivalent (AgEq)) over 1.81 m true width, or 56.2 ounces per ton (opT) AgEq over 5.9 feet (ft), including 283 gpt silver and 132.5 gpt gold (9,558 gpt AgEq) over 0.24 m true width, or 278.7 opT AgEq over 0.8 ft in hole COM108.

Terronera

At Terronera, recent drilling in the La Luz vein, located about 2,200 m northeast of the Terronera vein, has outlined a new high-grade, west plunging mineralized zone over 300 m long by 250 m deep starting approximately 100 m below surface and still open to surface and to depth (view long section here).

Recent drilling highlights are summarized in the table below and include 408 gpt silver and 58.6 gpt gold (4,512 gpt AgEq) over 1.14 m true width, or 131.5 opT AgEq over 3.7 ft, including 1,365 gpt silver and 238.0 gpt gold (18,025 gpt AgEq) over 0.9 m true width, or 525.5 opT AgEq over 2.8 ft in hole LL-02.

Silver equivalents are calculated at a ratio of 70:1 silver:gold.

Additional drilling of the Terronera vein continues to deepen the area of high-grade mineralization below the previously estimated resource. The main mineralized zone now measures over 1,400 m long by 400 m deep starting near surface, and remains open along strike to the southeast and down dip (view long section here).

Recent drilling highlights are summarized in the table below and include 226 gpt silver and 5.0 gpt gold (576 gpt AgEq) over 6.74 m true width, or 16.8 opT AgEq over 22.1 ft, including 527 gpt silver and 16.9 gpt gold (1,710 gpt AgEq) over 0.7 m true width, or 525.5 opT AgEq over 2.3 ft in hole TR09-6.

Luis Castro, Vice President of Exploration, commented, “These positive drill results confirm our view that both the El Compas and Terronera properties hold excellent exploration potential for the discovery of new veins and new mineralized zones. Our drill programs will break in mid-December for Christmas and we expect to receive final 2016 assays before we start drilling again in January. 

In order to include all significant drill results to year-end, management now expects to complete the updated resource estimates and new economic studies for El Compas and Terronera in March, at which time the Company will provide further guidance on its development plans for these two projects. Notwithstanding, exploration and pre-development work will resume at each site in January so as to avoid any potential timeline bottlenecks in the pending development schedules.

Godfrey Walton, M.Sc., P.Geo., Endeavour’s President and COO, is the Qualified Person who reviewed and approved this news release and supervised the drilling programs in Mexico. 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. 

About Endeavour – Endeavour Silver Corp. is a mid-tier precious metals mining company with three high-grade, underground, silver‑gold mines in Mexico. Since start‑up in 2004, Endeavour has grown its mining operations organically to produce 11.4 million ounces of silver equivalents in 2015. Development of Endeavour’s high-grade discovery on the Terronera property in Jalisco state, the permitted El Compas mine and plant in Zacatecas state, and the prospective Parral properties in Chihuahua state should facilitate the Company’s goal to become a premier senior producer in the silver mining sector.
