VANCOUVER, British Columbia, Dec. 02, 2021 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (TSX: EDR, NYSE: EXK) is pleased to report continued high-grade drill results from its 2021 exploration program at the Guanacevi Mine in Durango State, Mexico and the Bolañitos Mine in Guanajuato State, Mexico. Exploration drilling is ongoing at both operations and will continue in 2022.

Highlights from Recent Drill Results

Guanacevi

  • 1.97 gpt Au and 1,254 gpt Ag for 1,412 gpt AgEq over a 3.22 m ETW, including 3.6 gpt Au and 2,690 gpt Ag for 2,978 gpt AgEq over 0.2 m (UCM-67), extending the El Curso orebody along strike

  • 4.36 gpt Au and 1,450 gpt Ag for 1,798 gpt AgEq over a 3.18 m ETW, including 7.97 gpt Au and 4,568 gpt Ag for 5,206 gpt AgEq over 0.31 m (SCSU-11), extending the Santa Cruz South (SCS) orebody to depth

Bolañitos

  • 8.08 gpt Au and 151 gpt Ag for 797 gpt AgEq over a 1.67 m ETW, including 89.6 gpt Au and 880 gpt Ag for 8,046 gpt AgEq over 0.08 m (BS-04), on a new discovery, the Tepetateras vein, located south of current workings

  • 1.26 gpt gold and 241 gpt silver for 342 gpt AgEq over a 0.96 m ETW (BS-03), on the Lulu vein, south of current workings

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.

Dan Dickson, CEO, commented, “We continue to see exceptional drilling results within the El Curso and the Santa Cruz Sur systems at our Guanacevi silver mine. We have been operating at Guanacevi for more than 15 years and these encouraging results support our view that we can continue to extend the mine life.”

Mr. Dickson continued, “Endeavour was built on the drill bit and exploration will continue to be a cornerstone of our strategy as we pursue our vision of being a premier senior silver producer.”

At Guanacevi, underground drilling continues to expand down plunge extensions of the El Curso and the Santa Cruz South (SCS) orebodies (view Guanacevi longitudinal sections). From January through October, more than 14,000 metres in 38 holes have been drilled at Guanacevi from underground.   

At Bolañitos, surface and underground drilling has intersected multiple mineralized structures near current workings (view Bolanitos longitudinal sections). Tepetateras is a new area south of Bolañitos situated 1.7 kilometres from Endeavour Silver’s historic Golondrinas Mine. Since the beginning of the year, over 11,500 metres in 59 holes have been drilled at Bolañitos identifying mineralization in structures near current workings.
