Endeavour Silver Reports Positive Exploration Results for the Parral Project in

Chihuahua, Mexico Including 332 gpt Silver over 13.1 m True Width

VANCOUVER, British Columbia, Aug. 14, 2019 -- Endeavour Silver Corp. (NYSE: EXK; TSX: EDR ) reports positive results

from its ongoing 2019 exploration program on the Parral project in Chihuahua, Mexico.  Endeavour has completed 15 surface

and underground drill holes totaling 3,160 meters (m) and 462 underground channel samples in 3 blocks in the Sierra Plata

mine on the Veta Colorada vein system to date. 

The Veta Colorada (including the Sierra Plata and El Verde mines) was a past producing mining operation owned by Grupo

Mexico that closed in 1991 due to the low silver price. Endeavour acquired the Veta Colorada properties in 2016 along with the

past producing San Patricio and Palmilla mines and related silver veins in the Parral district. 

The Veta Colorada is a major silver vein structure that ranges from 1 to 30 m thick (average 5-10 m), was mined on 7 levels

down to 300 m depths below surface in places and has been traced for 7 kilometers.

Surface and Underground Drill Results

Endeavour has drilled 6 surface and 9 underground drill holes so far this year, about half of the planned program, to test an

area 600 m long by 500 m deep in and around the Sierra Plata mine workings. Every hole intersected strong silver

mineralization, mostly adjacent to old workings, indicating that historic mining focused on very high silver grades and left

behind significant high grade silver mineralization (view the Veta Colorada longitudinal section here).

Surface drilling highlights include 346 grams per tonne (gpt) silver over 9.6 m true width (11.1 oz per ton (opT) over 31.5 feet) in

hole VCS-02.  Underground drilling highlights include 332 gpt silver over 13.1 m true width (10.7 opT over 43.0 feet) in hole

VCU-05.  Several of the surface drill holes intersected old mine workings so the reported mineralized intervals represent only a

part of the original silver mineralized zones.

Underground Channel Sample Results

Endeavour sampled 3 blocks on level 7 to test an area 250 m long by 25 m vertically within the north part of the Sierra Plata

mine. Only minor work was needed to re-access and make safe the historic main haulage ramp into the mine.  The Company

dewatered the lowest mine levels last year, sampled old mine fill on levels 1 to 6, and recognized the opportunity to drill

unmined high grade in all mine levels and sample unmined high grade in the lower mine levels.

Channel sampling highlights include 2 samples exceeding 1,000 gpt such as 1,705 gpt silver over 0.55 m true width in channel

7+66 and 1,480 gpt silver over 0.95 m true width in channel 7+69.  The full width of the vein is not exposed in many of the mine

workings so the sampling results are only partly indicative of the silver mineralization. 

The highest grade samples in the channels are shown in the following table:

Bradford Cooke, Endeavour CEO commented, “With the success of our ongoing drilling and sampling exploration programs so

far this year, management views the Parral Project as having good potential to develop another new high grade silver mine. The

Parral Project is our largest exploration expenditure this year and represents an important part of our growth strategy.”

“We have re-conceptualized the development of the Parral Project as a potential two stage mine project due to the readily

accessible high grade mineralized blocks we have delineated underground. Given there are several toll mills operating in the

Parral district, and we have already applied for a mining permit requiring minimal new surface disturbance, we envisage a first

stage, small scale, high grade toll mine averaging around 200-250 tonnes per day to generate cash flow while we evaluate the

possibility of a second stage, larger scale, 1,000-2,000 tpd high grade mine that could become a new core asset.  We plan to

mine a bulk sample and process it at a local toll mill in Q3, 2019 so that we can prepare a preliminary economic assessment

for the stage one mine by year-end.”
