Endeavour Silver Continues to Intersect High-Grade Silver-Gold Mineralization and Extend the El Curso Orebody Along Strike and at Depth at its Guanacevi Mine

The Company recently amended its lease agreement relating to the El Curso property with Ocampo Mining SA de CV, a subsidiary of Grupo Frisco, to include rights to an additional 145 hectares of adjacent concessions covering the area between Porvenir Cuatro and Milache that connects the currently defined resources and workings. The drill results announced today are inclusive of these adjacent areas.

From early December 2021 through to mid-March 2022, 2,842 metres in 16 holes were drilled at Guanacevi from underground.

Highlights from Recent Drill Results

• 5.83 gpt Au and 1,278 gpt Ag for 2,534 gpt AgEq over a 7.5 m ETW, including 56.50 gpt Au and 22,562gpt Ag for 27,082 gpt AgEq over 0.47 m (UCM-93), extending the SCV orebody along strike
• 1.89 gpt Au and 975 gpt Ag for 1,126 gpt AgEq over a 7.6 m ETW, including 3.93 gpt Au and 3,690 gpt Ag for 4,004 gpt AgEq over 0.53 m (UCM-94), extending the SCV orebody along strike

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, "Guanacevi delivered exceptional exploration results in each of the past two years, and we expect this track record to continue. The drill results announced today are amongst some of the highest-grade intercepts we have seen at Guanacevi to date."
