VANCOUVER, British Columbia, Jan. 10, 2020 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (TSX: EDR, NYSE: EXK) reports production of 4.0 million silver ounces (oz) and 38,907 gold oz in 2019, for silver equivalent production of 7.1 million oz at an 80:1 silver:gold ratio. Silver production in the Fourth Quarter, 2019 was 939,511 oz and gold production was 9,578 oz, for silver equivalent production of 1.7 million oz.

Silver and gold production was lower in Q4, 2019 compared to Q4, 2018 due to the suspension of mining operations at the El Cubo mine during the quarter and lower throughput and grades at Bolanitos, partly offset by higher production at Guanacevi and new production at El Compas.  The Company withdrew its revised guidance in Q4, 2019, silver production missed the low range of revised guidance by 4% and gold production missed the low range of revised 2019 production guidance by 2%.

Silver equivalent production was slightly lower in Q4, 2019 compared to Q3, 2019 due to the suspension of mining operations at the El Cubo mine on November 30th, 2019.  Management initiated multiple measures at Guanacevi in Q2 and Bolanitos in Q3, 2019 to return the two operations to profitability. Continued improvement of tonnes mined, ore grades and oz produced are anticipated in 2020. 

Bradford Cooke, Endeavour CEO, commented, “The Company’s performance last year was negatively impacted by operating issues at all four mines.  We made sweeping changes to the mining operations in Q2 and Q3 and as a result, we are finally seeing production turning around, led by Guanacevi.  Endeavour expects higher production at each of its three mines in 2020.”

“We continued to advance our Terronera and Parral projects, with additional engineering trade off studies completed for Terronera and continued exploration drilling at Parral during the Fourth Quarter.  A final updated Pre-Feasibility Study for Terronera is being completed this month and an initial Preliminary Economic Assessment at Parral is expected in Q1, 2020.”

Production increased compared to Q4, 2018 primarily due to higher throughput and higher ore grades.  Throughput and ore grades increased year-on-year as a result of the operational changes made to improve mine output, while increased access to the higher grade ores in the Milache and Porvenir Cuatro Extension (P4E) orebodies replaced production from the lower grade Porvenir Norte and Santa Cruz orebodies, which are now closed. Fourth quarter throughput and grades were the highest for the year as the operating improvements implemented in Q2 started to deliver results. Mine development of the Milache and P4E orebodies were on plan but development of the SCS orebody lagged behind plan.  Silver production attained the low range of revised 2019 guidance and gold production exceeded the high range of the revised guidance by 1%.


Production decreased compared to Q4, 2018 primarily due to lower throughput and lower silver and gold grades. Mine output declined year-on-year because the mine plan had to be re-sequenced to allow for blending of high and low arsenic ores, equipment availability issues and mine development fell behind plan which resulted in lack of access to ore.  The Company initiated operational measures in Q3, 2019 to improve mine output which should benefit production in 2020.  Silver and gold production did not meet revised 2019 guidance, missing by 11% and 1%, respectively.

El Compas

Production has no prior year for comparison but decreased compared to Q3, 2019 primarily due to lower grades, partly offset by slightly higher throughput. The grade variation reflects different parts of the Orito orebody.  In Q4, 2019, throughput was on plan, however silver and gold production were below plan. During the first three quarters of commercial production, throughput was 95% of plan, while gold grades exceeded plan by 7% and silver grades were below plan by 10%. Silver recoveries over this period exceeded plan by 8%, while gold recoveries fell short of plan by 3%. Final refining settlements on Q3 concentrate production resulted in lower gold contained than estimated. These adjustments are recognized in Q4 production results and impact reported recoveries. Going forward recoveries are expected to be higher than 80%.  Silver and gold production met revised 2019 guidance.

El Cubo

The Company suspended mining operations at the El Cubo underground mine on November 30, 2019 as reserves were exhausted.  The mine, plant and tailings facilities are on short term care and maintenance, while management conducts an evaluation of the alternatives including final closure.  During October and November, the mine processed 39,206 tonnes grading 106 Ag g/t and 1.16 Au g/t producing 122,780 silver oz and 1,161 gold oz, a significant decrease from both prior year and the previous quarter.  Silver and gold production did not meet revised 2019 guidance, missing by 9% and 13%, respectively.

Suspension costs are estimated to be approximately $3.5-4.0 million, primarily expensed in Q4, 2019, the bulk of which is final severance payments for most of the employees. Company management and contract personnel continue to maintain the security of the mine, plant and tailings facilities. Management is evaluating alternatives for the plant and related facilities including moving certain components to other mines or development projects such as Terronera and Parral to reduce their future capital costs. The mining equipment will be relocated to Endeavour’s other operating mines, particularly Bolanitos, to help facilitate increasing the mine output to fill the plants to their capacities.
