Endeavour Silver Corp. (TSX: EDR) (NYSE: EXK) has intersected high grade gold-silver mineralization in its 2021 exploration drill program to expand the Melladito and Belen orebodies at the Bolañitos Mine in Guanajuato State, Mexico.   The Company is currently producing from four orebodies at Bolañitos: Plateros, Lucero, San Miguel and Melladito. Exploration drilling is ongoing along the Melladito and Belen veins (view longitudinal sections here).

Highlights from the latest drill results include:

• 8.09 grams per tonne (gpt) gold and 1,044 gpt silver for 1,611 gpt silver equivalent (AgEq at an 70:1 silver:gold ratio) over a 1.0 metre true width (47.0 oz per short ton AgEq over 3.3 feet), including 14.2 gpt gold and 1,974 gpt silver for 2,966 gpt AgEq over 0.26 m (86.5 opT AgEq over 1.0 ft) in drill hole BN-64 on the Melladito HW vein
• 4.43 gpt gold and 148 gpt silver for 458 gpt AgEq over a 2.34 m true width (13.4 opT AgEq over 7.7 feet), including 13.22 gpt gold and 129 gpt silver for 1,054 gpt AgEq over 0.19 m (30.7 opT AgEq over 0.7 ft) in drill hole BL1.5S-4 on the Belen HW vein

Luis Castro, Vice President of Exploration, commented, “We continue to intersect strong drill results as we step out from the current margins of the Melladito and Belen orebodies, with a number of other targets to drill, along both the Melladito and Belen veins.”

Drill results are summarized in the following table:

• Silver equivalents are calculated at a ratio of 70:1 silver:gold. All widths are estimated true widths.
• Drill holes BN-63, BN-69, BN-70, BL1.5S-5, and BL2.5S-2 returned no significant results

Qualified Person and QA/QC – Dale Mah, P.Geo., Vice President Corporate Development of Endeavour Silver, is the Qualified Person who reviewed and approved the technical information contained in this news release. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All samples are split at the local field office and shipped to SGS Labs, where they are dried, crushed, split and 250 gram pulp samples are prepared for analysis. Gold is determined by fire assay with an atomic absorption (AAS) finish and silver by aqua regia digestion with ICP finish, over-limits by fire assay and gravimetric finish.
