Production in 2018 was underpinned by the El Cubo mine, which saw higher mine output, silver and gold grades and recoveries.
The shortfall on 2018 production guidance was pinned on lower mine output and silver grades at Guanaceví, lower gold grades at Bolañitos and delays in achieving commercial production at El Compas.
Endeavour reported full-year production of 5.5 million ounces silver and 52,967oz gold, or 9.5Moz silver-equivalent at a 75:1 silver-gold ratio.
Silver output in the December quarter was 1.39Moz and gold production totaled 13,117oz, resulting in 2.4Moz silver-equivalent.
"All in all, 2018 was quite a transition year for Endeavour Silver. We saw improved performance from El Cubo, but declining performance at Bolañitos, where new mineralised zones were discovered and at Guanaceví, where two new orebodies are being developed," said CEO Bradford Cooke.
Endeavour, capitalised at C$387.75 million, closed 1.33% or 4c lower in Toronto Thursday at $2.97. The stock has eked out a 1.37% gain over the past 12 months, and last peaked at $4.40 early in July.
