Endeavour Silver Drilling Intersects New High-Grade Gold-Silver Mineralization in Melladito Vein at Bolanitos Mine, Guanajuato, Mexico
Endeavour Silver Drilling Intersects New High-Grade Gold-Silver Mineralization
in Melladito Vein at Bolanitos Mine, Guanajuato, Mexico
VANCOUVER, British Columbia , May 20, 2020 -- Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) announces that
exploration drilling in Q1, 2020 intersected new high-grade gold-silver mineralization in the Melladito vein at the Bolanitos mine
in Guanajuato, Mexico. A total of 14 holes were drilled and 8 holes intersected high grades over minable widths (view
longitudinal section here).
Drilling highlights of 8 core holes include the following intersections:
• 24.3 grams per tonne (gpt) gold and 787 gpt silver over a 1.5 meter (m) true width in hole BN27 (3,217 gpt or 93.8 oz
per ton (opT) silver equivalents (AgEq) at a 100:1 silver:gold ratio)
• 12.5 gpt gold and 50 gpt silver over a 1.1 m true width (1,300 gpt or 37.9 opT AgEq)
• 7.37 gpt gold and 170 gpt silver over a 2.7 m true width (907 gpt or 26.4 opT AgEq)
The eight drill holes outline a new mineralized zone 100 m long by 200 m deep, open in all directions. It could connect with
the historic high-grade San Ramon mine workings immediately west of and the San Pablo mine workings immediately east of
the drill holes. This part of the Melladito vein was not previously explored and represents an exciting new area for resource
estimation and mine development.
Bradford Cooke, Endeavour Director and CEO, commented, “Last year at Bolanitos, we were successful in outlining new
resources in the San Miguel vein, now under development, and we expect to commence mining at San Miguel in Q3, 2020.
This year, we are discovering new resources in the Melladito vein, which should allow us to develop and mine there next year,
as the orebody is only 300 m from the La Luz Ramp and 300 m from the San Miguel ramp.”
“Exploration activities were halted on April 1, 2020 due to the government mandated suspension of non-essential activities
during the COVID-19 pandemic. Now that the government has decreed that the mining industry can go back to work, subject
to certain conditions, the exploration team will resume drilling at Bolanitos and other projects on or after June 1, 2020.”

news release and supervised the drilling programs in Mexico. A Quality Control sampling program of reference standards,
blanks and duplicates is used 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
is determined by fire assay with an atomic absorption (AA) finish and silver by aqua regia digestion and ICP finish, over-limits
by fire assay and gravimetric finish.
