Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) reports positive infill drill results from its ongoing 2019 exploration program of the Veta Colorada vein on the Parral project in Chihuahua, Mexico.
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 low silver prices. Mineralization occurs in a major silver vein structure that ranges from 1 to 30 metres (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.
Endeavour has drilled an additional 10 underground holes reported herein for a total of 25 drill holes so far this year, 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 below the lowest mine level (view Veta Colorada longitudinal section here).
Recent drilling highlights include 308 grams per tonne (gpt) silver over 11.6 m true width (9.0 oz per ton (opT) over 38.1 feet) in hole VCU-16. Several drill holes intersected two mineralized zones, the Veta Colorada and the HW Veta Colorada in the hanging wall, with a total true width of mineralization up to 16.5 m in hole VCU-17.
Luis Castro, Vice President, Exploration commented, “These infill drill holes at the Sierra Plata mine on the Veta Colorada vein continue to outline two significant, parallel mineralized zones over a 400 m length by 300 m depth below mine level 7. These mineralization zones are extensions of the orebodies mined by Grupo Mexico decades ago.”
“Our surface drilling and underground sampling results reported earlier this year (see August 14, 2019 news release here) showed that substantial high-grade silver mineralization remains in the area of the old mine workings above mine level 7. Management views the Parral Project as having good potential to develop into another new high grade silver mine for Endeavour Silver.”

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 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.
