Endeavour Silver Ends the Year on a Strong Note; FY2021 Annual Production Surpasses Upper End of Guidance

VANCOUVER, British Columbia, Jan. 11, 2022 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. ("Endeavour" or the "Company") (NYSE: EXK; TSX: EDR) is pleased to report full year 2021 production of 4,870,787 silver ounces (oz) and 42,262 gold oz, for silver equivalent¹ ("AgEq") production of 8.3 million oz. Fourth quarter production was 1,443,564 silver oz and 9,446 gold oz, for silver equivalent production of 2.2 million oz AgEq.

The Company's 2021 full year production exceeded the upper range of its guidance of between 7.7 million oz and 8.0 million oz AgEq (revised upward in October) due to continuing strong performance at Guanacevi with higher grades and tonnage milled. Annual silver production exceeded guidance by 3% while gold production was in line with the upper range of guidance.

"Steady performance at Bolanitos, together with record mill throughput, grade and production at Guanacevi boosted our 2021 consolidated production beyond the upper end of our increased guidance," said Dan Dickson, Endeavour's Chief Executive Officer. "Last year was a great year due to the excellent efforts of our entire team and we are in a strong position going into 2022."

Q4 and FY2021 Highlights

• Exceeded Production Guidance: Consolidated production remained strong as silver and gold production at each mine met or exceeded revised 2021 guidance and exceeded plan.
• Guanacevi Continued to Outperform: Silver and gold grades continued to deliver well above plan and throughput approached plant capacity.
• Bolanitos Performance Remained Steady: Silver grades and plant throughput exceeded plan with gold grades slightly below plan.
• Metal Sales and Inventories: Sold 1,413,699 oz silver and 8,715 oz gold, held 1,028,340 oz silver and 1,044 oz gold of bullion inventory and 54,270 oz silver and 2,630 oz gold in concentrate inventory at year end. Management continued to be bullish on precious metal prices and withheld a portion of metal sales in the fourth quarter, consistent with the levels held as at September 30, 2021.
• Encouraging Brownfields Exploration Results from Guanacevi and Bolanitos: Drilling continued to intersect high-grade gold-silver mineralization in the Santa Cruz vein at Guanacevi and intersect multiple mineralized structures near current workings at Bolanitos.
• Positive Greenfields Exploration Results from the Parral Project: Drilled over 14,000 metres targeting several areas along the La Colorada vein with encouraging results to expand the mineral resource estimate.
• Continued to Advance the Terronera Project: The Terronera Project Technical Report, authored in accordance with National Instrument 43-101 was filed on SEDAR and EDGAR on October 25, 2021. Work continued on final detailed engineering, early earth works, critical contracts and procurement of long lead items.   The financing and final permitting processes are progressing, however, the current surge in COVID-19 cases caused by the Omicron variant has extended the anticipated timeline. 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.
• Sold El Cubo Assets: The Company sold its El Cubo assets in Guanajuato, Mexico to Guanajuato Silver Co (formerly Vangold Mining Corp) for US$15 million plus contingent payments up to US$3 million in a transaction that closed April 9, 2021.
• Suspended Operations at El Compas: Management suspended operations at El Compas in mid-August and is currently evaluating its alternatives for the asset.
• Acquired Bruner, an Advanced Stage Exploration Project: Ideally situated within Nevada's Walker Lane NW trending mineral belt, this acquisition closed on September 1, 2021.

Q4 2021 Mine Operations

Consolidated silver production increased by 29% to 1,443,564 ounces in Q4 2021 compared to the prior year quarter, primarily driven by a 31% increase in silver production at the Guanacevi mine and a 42% increase in silver production at the Bolanitos mine offset by the suspension of operations at the El Compas mine. Gold production decreased by 25% to 9,446 ounces due to a 19% decrease in gold production at Bolanitos mine and the suspension of operations at the El Compas mine offset by a 21% increase in gold production at the Guanacevi mine.  

Guanacevi throughput in Q4 2021 was consistent with Q4 2020 but silver grades and gold grades were each significantly higher. Guanacevi throughput exceeded plan and mining the new higher grade El Curso orebody has led to significantly improved grades and mine plan flexibility. Additionally, supplies of local third-party ores continued to supplement mine production, amounting to 14% of quarterly throughput and contributing to the higher ore grades.

Bolanitos Q4 2021 throughput was consistent with Q4 2020 with increased silver grades and decreased gold grades. Silver production increased by 42% while gold production decreased by 19% at the Bolanitos mine.
