Endeavour Silver Reports Positive Drill Results for the Parral Project

 

(All amounts are in US dollars, unless otherwise stated)

VANCOUVER, British Columbia, Dec. 16, 2021 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (TSX: EDR, NYSE: EXK) is pleased to report positive drill results from its ongoing exploration program at the 3,432-hectare Parral project situated in the State of Chihuahua, Mexico. 

During the last 11 months, until the end of November, the Company has drilled over 14,000 metres in 59 holes targeting several areas along the La Colorada vein.

Highlights from Recent Drill Results

• 2,846 gpt Ag, 0.65% Cu over a 0.89 m ETW, including 3,380 gpt Ag, 0.77% Cu over 0.75 m (VCS-10)
  

• 840 gpt Ag, 0.11 gpt Au, 0.25% Cu, 9.09% Pb and 4.74% Zn for 1,288 gpt AgEq over a 2.77 m ETW, including 1,585 gpt Ag, 0.26 gpt Au, 0.55% Cu, 34.88% Pb and 4.38% Zn for 2,755 gpt AgEq over 0.36 m (VCU-38)
  

• 708 gpt Ag, 0.55 gpt Au, 0.16% Cu, 10.95% Pb and 12.38% Zn for 1,504 gpt AgEq over a 1.23 m ETW, including 1,130 gpt Ag, 0.91 gpt Au, 18.95% Pb and 18.70% Zn for 2,406 gpt AgEq over 0.69 m (VCU-50)
  

Abbreviations include: gpt: grams per tonne; Au: gold; Ag: silver; Cu: copper; Pb: lead; Zn: zinc; ETW: estimated true width; m: metre; HW: hanging wall. Silver equivalents are calculated at a ratio of 80:1 silver:gold, silver price of $23 per troy ounce, copper price of $3.45 per pound, lead price of $0.90 per pound and zinc price of $1.20 per pound.

“The Parral project continues to deliver great results,” commented Dan Dickson, Chief Executive Officer. “Following limited drilling in 2020 due to the pandemic, it was a priority for our exploration team to re-start the exploration program at Parral this year to expand on the mineral resource estimate we published on the project in early 2020. Our goal is to continue the drill program at Parral in 2022 as we get closer to achieving the scale required to support a positive economic assessment.”

The Parral project, which was acquired by Endeavour Silver in 2016, is in Hidalgo de Parral, a large historic silver mining district adjacent to the city of Parral, in the State of Chihuahua, Mexico. The project district comprises classic, high-grade silver, epithermal vein deposits, characterized by low-sulphidation mineralization. The property is accessible by paved and gravel roads and has access to the local power grid.

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, which occurs in a major silver vein structure that ranges from 1 to 30 metres thick, was mined seven levels down to 300-metre depths below surface in places and was traced for seven kilometres.

The Company filed a NI 43-101 technical report on the Parral project, State of Chihuahua, Mexico on March 14, 2020. As of December 31, 2019, Parral had estimated indicated mineral resources of 613,000 tonnes, containing 4.0 million ounces of silver grading 207 g/t, 6,800 ounces of gold grading 0.35 g/t, 17.5 million pounds of lead grading 0.63%, and 16.5 million pounds of zinc grading 0.61%. Inferred mineral resources are estimated to total 4.04 million tonnes containing 35.0 million ounces of silver grading 269 g/t, 62,800 ounces of gold grading 0.48 g/t, 65.0 million pounds of lead grading 0.35%, and 64.3 million pounds of zinc grading 0.35%.

Due to the COVID-19 pandemic, the Company suspended the Parral drill programs in early 2020 and resumed drilling in 2021.

The Parral drill results are summarized in the following tables:
