VANCOUVER, British Columbia, Sept. 26, 2022 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (TSX: EDR, NYSE: EXK) (“Endeavour” or the “Company”) is pleased to report positive drill results from its ongoing drill program at the Guanacevi Mine in Durango state, Mexico. Drilling continues along the prolific Santa Cruz vein in two areas (view Santa Cruz Vein longitudinal section), with the objective to convert, expand, and discover new resources.

The 2022 drill program has continued to focus on the El Curso property, establishing lateral and vertical extents of the mineralized zone between the Porvenir Cuatro and Milache mines. The exploration and exploitation rights to the El Curso property were obtained in 2019 from Ocampo Mining S.A. de CV., and have become an integral contributor to the operation. Recently, under the same agreement terms, the Company has tested the northwest extension of the Porvenir Dos orebody with encouraging results from initial drilling.

Highlights from Recent El Curso Drill Results

• 3.50 gpt Au and 1,150 gpt Ag for 1,430 gpt AgEq over a 1.16 m ETW, including 12.80 gpt Au and 4,240 gpt Ag for 5,264 gpt AgEq over 0.24 m (UCM-102)

• 3.54 gpt Au and 1,129 gpt Ag for 1,412 gpt AgEq over a 7.28 m ETW, including 25.40 gpt Au and 7,080 gpt Ag for 9,112 gpt AgEq over 0.43 m (UCM-106)
  

Highlights from Recent Porvenir Dos Drill Results

• 1.43 gpt Au and 967 gpt Ag for 1,081 gpt AgEq over a 2.43 m ETW, including 3.64 gpt Au and 5,120 gpt Ag for 5,411 gpt AgEq over 0.23 m (APD-03)
  

• 1.60 gpt Au and 1,460 gpt Ag for 1,589 gpt AgEq over a 1.17 m ETW, including 2.91 gpt Au and 3,340 gpt Ag for 3,573 gpt AgEq over 0.25 m (APD-04)

Abbreviations include: gpt: grams per tonne; Au: gold; Ag: silver; ETW: estimated true width; m: metre; HW: hanging wall. Silver equivalents are calculated at a ratio of 80:1 silver:gold.

“We are encouraged by the drill results at Guanacevi, as we continue to delineate high grades in areas which are proximal to the mill and historic working areas. The results announced today demonstrate both growth and steady improvement of the deposit and mine plan,” stated Dan Dickson, Chief Executive Officer. “Our focus remains on delineating mineralized extensions to mining horizons and resource growth.”
