Endeavour Silver Reports High Grade Silver-Gold Drill Intersections at the Guanacevi Mine, Durango, Mexico

VANCOUVER, British Columbia, June 05, 2019 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (NYSE: EXK; TSX: EDR) reports several high-grade silver-gold intersections in the Porvenir Centro, Porvenir Norte and Santa Cruz orebodies along the Santa Cruz vein drilled in late 2018-early 2019 at the Guanacevi mine in Durango, Mexico. 

A total of 17 underground drill holes were completed of which 7 holes intersected high grades over mineable widths to extend the three orebodies outside of the current mine plans (view longitudinal section here).

Drilling highlights in the Porvenir Norte orebody include 251 grams per tonne (gpt) silver and 0.93 gpt gold for 325 gpt silver equivalent (Ag Eq calculated at an 80:1 Au:Ag ratio) over a 3.0 metre (m) true width (9.5 oz per short ton (opT) AgEq over 9.8 feet (ft) in hole UG-61). 

Drilling highlights in the Santa Cruz orebody include two intersections in parallel veins, 2,175 gpt silver and 2.93 gpt gold for 2,409 gpt Ag Eq over a 1.0 m true width (70.2 opT AgEq over 3.3 feet (ft)); and 579 gpt silver and 0.78 gpt gold for 642 gpt AgEq over 3.9 m (18.7 opT over 12.8 ft) in hole UG-75. 

Bradford Cooke, Endeavour director and CEO, commented, “We continue to be encouraged by our positive exploration results at Guanacevi.  Recent drilling has extended high grade silver-gold mineralization to depth at all three of our original orebodies, which should help to increase resources at Guanacevi.”

“Our operations group recently adjusted the 2019 Guanacevi mine plan to halt new development and mine accessible reserves in the original orebodies and accelerate the development and production of our two new orebodies, Milache and SCS, which are higher grade than the current reserves in the original orebodies.  These actions are helping to boost metal production and reduce operating costs so the mine can return to positive free cash flow at current metal prices.”
