Endeavour Silver Produces 1,048,100 oz Silver and 11,109 oz Gold for 1.9 Million oz Silver Equivalents in Q1, 2021

Endeavour Silver Corp. (TSX: EDR, NYSE: EXK) reports production of 1,048,100 silver ounces (oz) and 11,109 gold oz in Q1, 2021, for silver equivalent (AgEq) production of 1.9 million oz at an 80:1 silver:gold ratio. Silver production increased 22% and gold production increased 31% compared to Q1, 2020, due primarily to higher ore grades mined and processed.

2021 First Quarter Highlights

• Consolidated Production on Plan: Silver equivalent production at each mine is on track to meet or exceed 2021 production plans.
  
  
• Guanacevi Production on Plan: Higher silver and gold grades were partly offset by slightly lower throughput than planned during the quarter.
  
  
• Bolanitos Ahead of Plan: Processed tonnes, gold grade and gold recoveries are ahead of plan, partly offset by slightly lower silver grades and recoveries compared to plan.
  
  
• El Compas Ahead of Plan: Processed tonnes, and gold grade are ahead of plan, partly offset by slightly lower silver grade and lower gold recoveries compared to plan.
  
  
• Metal Sales and Inventories: Sold 623,379 oz silver and 10,663 oz gold, held 523,235 oz silver and 1,123 oz gold of bullion inventory and 6,582 oz silver and 566 oz gold in concentrate inventory. Management withheld metal from sale during the price correction over last two weeks of March and plans to sell the withheld metal inventory in anticipation of a precious metal prices rebound in Q2, 2021.
  
  
• Signed Definitive Agreement to Sell the El Cubo Assets: Advanced sale of the El Cubo mine in Guanajuato, Mexico to VanGold Mining Corp for $15 million in cash and share payments, with up to $3 million in contingent payments. The transaction is anticipated to close in April 2021.
  
  
• Shares Included in Two Major Indices: The Company's common shares were added to the S&P/TSX Composite Index and the NYSE Arca Gold Miners Index (GDX ETF) in March.
  
  
• Announced Management Succession Plan: Bradford Cooke plans to step down as CEO and assume the role of Executive Chair of the Company following the AGM on May 12, 2021. Dan Dickson has been nominated to the role of CEO and Christine West has been nominated to become the CFO. Both Mr. Dickson and Ms. West have been key members of management for over 13 years and will lead the Company into its next phase of growth.
  

Bradford Cooke, Endeavour CEO, commented, "It is gratifying to see the Company firing on all cylinders, with the mining operations meeting or exceeding expectations and the development team advancing the Terronera project to drive the next phase of growth. I will look forward to supporting Dan and Christine in their new roles as they build a bigger and better Company."

Mine Operations

Consolidated silver and gold production were both higher in Q1, 2021 compared to Q1, 2020 due to a significant increase in ore grades at Guanacevi and improved throughput and ore grades at Bolanitos.

Guanacevi silver and gold grades were higher compared to Q1, 2020 and well above plan. In February, unusually cold weather in northern Mexico resulted in power curtailments effecting mine and process plant production over a three-day period. In March, throughput was lower than initially planned as the refurbishment of the tailings filter presses impacted daily throughput. The plant throughput is expected to return to its 1200 tonnes per day capacity in April. Stockpiled ore inventory increased during the quarter as the mine output was on plan. With the higher metal prices, supplies of local third-party ores continued to supplement mine production, amounting to 10% of quarterly throughput, and contributed to the higher ore grades. Ore grades are expected to revert to plan in Q2, 2021 and for the remainder of the year.

Bolanitos and El Compas processed tonnes, and gold grade were all higher compared to Q1, 2020, partly offset by lower silver grades and both mines are slightly ahead of planned production. Settlement of El Compas concentrates resulted in lower recoveries during the quarter.

COVID-19 pandemic remains prevalent in Mexico, and at the Company's business locations, process and protocols remain in place to ensure staff and workers as well as our communities remain as safe as possible.
