Endeavour Silver Intersects New High-Grade Gold-Silver Mineralization on the El Curso Property at the Guanacevi Mine in Durango, Mexico

 

 

 

 

 

Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) announces that exploration drilling through Q1, 2020 intersected new high-grade gold-silver mineralization in the Santa Cruz vein on the El Curso property at the Guanacevi mine in Durango, Mexico.  A total of 18 holes were drilled, 12 of which hit high grades over minable widths (view longitudinal section here).

 

Drilling highlights of 12 core holes include the following intersections:

 

  • 1,085 gpt silver and 3.25 grams per tonne (gpt) gold over 10.0 meters (m) true width in hole UCM-27 (1,410 gpt or 41.1 oz per ton (opT) silver equivalents (AgEq) over 32.8 feet (ft) at a 100:1 silver:gold ratio)
  • 762 gpt silver and 1.87 gpt gold over 5.1 m true width in hole UCM-26 (949 gpt or 27.7 opT AgEq over 16.7 ft)
  • 986 gpt silver and 1.43 gpt gold over a 4.8 m true width in hole UCM-25 (1,129 gpt or 32.9 opT AgEq over 15.7 ft)

 

Drill holes UCM-11 to 15 continue to delineate the northwest extension of the original P4 orebody onto the El Curso property.  This P4 extension now measures 200 m long by 300 m deep, still open at depth.  Endeavour is currently mining this P4 extension as well as the Milache and SCS orebodies.

 

Drill holes UCM-19 to 28 have discovered a new mineralized zone to the west of P4 extension, half-way towards the Milache orebody.  This new mineralized zone now measures 250 m long by 150 m deep, still open along strike and at depth.  Drilling stopped at the end of March due to the COVID-19 pandemic and is expected to recommence in June.

 

Bradford Cooke, Endeavour Director and CEO, commented, “Last year at Guanacevi, we were successful in outlining new resources on the El Curso property, and we commenced mining there in late Q3, 2019.  This year, we continue to discover new resources in the Santa Cruz vein on El Curso which should add to our mine life at Guanacevi.”

 

Drilling results are summarized in the following table:
