Endeavour Silver Intersects High-Grade Silver-Gold Mineralization at the Guanacevi Mine in Durango, Mexico

Rhea-AI Summary

Endeavour Silver has announced promising results from its 2021 exploration drill program at the Guanacevi Mine in Mexico, targeting the El Curso orebody. Significant findings include up to 3,764 gpt silver equivalent over a 2.6 m width. The ongoing exploration seeks to connect El Curso with nearby orebodies, potentially forming a continuous orebody spanning 1,500 m by 400 m. This could enhance production capabilities, given its historical performance with the Porvenir Norte orebody. The future prospects for the Guanacevi Mine appear highly positive.

Positive

• High-grade silver-gold mineralization discovered at El Curso.
• Results include 3,764 gpt AgEq over a 2.6 m width, indicating strong mineralization.
• Plans to connect El Curso with Milache and Porvenir Cuatro could expand the orebody significantly.

Negative

• None.

VANCOUVER, British Columbia, May 04, 2021 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (TSX: EDR, NYSE: EXK) has intersected high grade silver-gold mineralization in its 2021 exploration drill program to expand the El Curso orebody at the Guanacevi Mine in Durango State, Mexico.   The Company is currently producing from three orebodies at Guanacevi: Milache, El Curso and SCS. Exploration drilling is ongoing at El Curso and SCS (view longitudinal section here).

Highlights from the latest drill results include:

• 3.27 grams per tonne (gpt) gold and 2,753 gpt silver for 2,982 gpt silver equivalent (AgEq at an 70:1 silver:gold ratio) over a 4.1 metre (m) true width (87.0 oz per short ton (opT) AgEq over 13.5 feet (ft)), including 0.6 gpt gold and 18,752 gpt silver for 18,794 gpt AgEq over 0.3 m (548.2 opT AgEq over 1.0 ft) in drill hole UCM-48
• 4.29 gpt gold and 3,464 gpt silver for 3,764 gpt AgEq over a 2.6 m true width (109.8 opT AgEq over 8.5 feet (ft)), including 25.7 gpt gold and 19,390 gpt silver for 21,189 gpt AgEq over 0.3 m (618.0 opT AgEq over 1.0 ft) in drill hole UCM-50

Luis Castro, Vice President of Exploration, commented, “We continue to intersect excellent drill results as we step out from the current margins of the El Curso orebody. There remains an additional 100 m to drill until we connect El Curso with the Milache orebody to the west, and there is a similar gap to fill to connect El Curso with the Porvenir Cuatro orebody (previously mined) to the east.”

“Ultimately, we anticipate that Porvenir Cuatro, El Curso and Milache will all connect to form one continuous orebody over a 1,500 m length by 400 m vertical extent. This would make it comparable to the original Porvenir Norte orebody which supported production at Guanacevi for over 14 years. The future is looking bright for Guanacevi.”

Drill results are summarized in the following table:
