Vancouver, Canada – October 24, 2017 – Endeavour Silver Corp. (NYSE: EXK, TSX: EDR) announces that exploration drilling on the Parral property in Chihuahua State, Mexico has verified high grade silver mineralization within the Argentina-Remedios area of the Veta Colorada, which was drilled but never mined by a previous owner, IMMSA.

Industrial Minera Mexico, S.A. de C.V. (IMMSA) operated a high grade silver mine on the Veta Colorada until 1990 and on closing left behind a 32.1 million oz historical silver resource contained in 4.0 million tonnes (t) grading 248.5 grams per tonne (gpt).  A qualified person has not done sufficient work to classify this historical estimate as a current mineral resource, Endeavour has not verified the historical resource and is not relying on it as a current mineral resource.

Twenty-one drill holes totaling 6,928 metres (m) of core were drilled to test the portion of the historic resource located within the Argentina-Remedios area of the Veta Colorada. (View long section here). The drill holes were spaced at approximately 100 m centres over an area 400 m long by 400 m deep.

Drilling highlights include 457 gpt silver over a 9.3 m true width (13.3 opT Ag over 30.5 feet (ft)) in hole CV26.5-1.  Another high grade intercept assayed 4,641 gpt silver over a 2.3 m true width (135.3 opT Ag over 7.5 ft) in hole CV27-2.

Results for 12 high grade drill intercepts are summarized in the table below.

Luis Castro, Vice President, Exploration for Endeavour Silver, commented, “These encouraging drill results help to verify the portion of the historic resource within the Argentina-Remedios area of the Veta Colorada.  A new resource estimate will be prepared at year-end for release in the 1st quarter of 2018. 

“Drilling is ongoing at other areas of the Parral property such as Palmilla and San Patricio, where there was a history of high grade mining but very little drilling and no previous resources, to test for new silver resources.  We plan to release additional drill results during the 4th quarter of 2017.”

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.
