Endeavour Silver Corp.  (NYSE: EXK) (TSX: EDR) is pleased to report third quarter 2022 production of 1,458,448 silver ounces and 9,194 gold oz, for silver equivalent¹ production of 2.2 million oz, totalling 6.3 million AgEq oz for the 9 months ended September 30, 2022. Annual production is trending towards the upper end of the guidance range for the year, forecasted at 7.6 to 8.0 million AgEq oz.

“The ore grades processed at Guanacevi continue to exceed plan, which has positioned the Company to meet the upper end of our improved production guidance. The outperformance is well timed, as we continue to face financial pressure from lower metal prices and inflationary effects on inputs,” stated Dan Dickson, Chief Executive Officer. “We announced impressive drill results from our exploration program in the quarter at Guanacevi, where we are extending and defining the vertical extents of the Porvenir Dos orebody, which is near historic working areas.”

Q3 2022 Highlights

• Steady Focus on Safety Improvement: Lost time injury frequency and severity rates continue to trend down as employees keep focus on our proactive safety orientated culture through the “Te Cuido” safety philosophy.
• Guanacevi Continued to Outperform: Silver and gold production on plan, driven by higher grades.
• Bolañitos Performance Remained Steady: Strong silver production, higher silver grades and increased throughput were offset by the impact of lower than expected gold production and gold grades.
• Metal Sales and Inventories: Sold 1,327,325 oz silver and 8,852 oz gold during the quarter. Held 1,527,548 oz silver and 3,210 oz gold of bullion inventory and 2,769 oz silver and 144 oz gold in concentrate inventory at quarter end.
• Guanacevi Delivers Positive Drill Results: Further exploration results from near mine drilling in easily accessible areas are intersecting high-grade silver-gold mineralization on the El Curso property (see News Release dated September 26, 2022).
• Positive Exploration Results at Parral: Drilling is intersecting some of the highest grades to date, with significant widths along the Veta Colorada structure (see News Release dated September 8, 2022).
• Advancing the Terronera Project: The early works program initiated last year continued, including detail engineering, critical contracts and the procurement of long lead items. Extensive due diligence work continued for project financing. The Company intends to make a formal construction decision subject to completion of a financing package and receipt of additional amended permits in the coming months.
• Completed the Acquisition of the Pitarrilla Project: The world’s largest undeveloped silver project that will form the cornerstone of the Company’s growth profile, together with Terronera and Parral.
• Divested the El Compas Property to Grupo ROSGO: Completed the sale of the property and the plant for US$5 million over five years (see News Release dated September 12, 2022).

Q3 2022 Mine Operations

Consolidated silver production increased 12% to 1,458,448 ounces in Q3 2022 compared to Q3 2021, primarily driven by increased silver production at the Guanacevi mine. The high grades at the El Curso orebody have led to improved production, allowing for production targets to be met during a period of decreased plant throughput. Local third-party ores continued to supplement mine production, amounting to 12% of quarterly processed tonnes and contributing to higher ore grades. Guanacevi throughput was 4% higher than the prior quarter but lower than plan, due to heavy rainfall in a short, concentrated period during September. Management continues to review alternatives to further increase throughput above the current 1,200 tpd capacity with changes in grinding size and leach time.

Gold production decreased by 13% to 9,194 ounces primarily due lower gold grades mined at the Bolañitos mine. The increased gold production from Guanacevi offset the gold produced from the El Compas mine, which suspended operations in Q3, 2021.

Bolañitos Q3 2022 throughput was 3% lower Q3 2021 with silver grades 5% higher and gold grades 5% lower. Silver production increased by 2% while gold production decreased by 11% at the Bolañitos mine. The change in grades were due to typical variations in the ore body.
