Mexico-focused miner Endeavour Silver warned on Thursday that it would fall short of its 2018 production guidance and that its costs would also be affected, citing delayed commercial production at its El Compas mine, lower grades at Bolañitos and lower mine output at Guanaceví. In the third quarter, TSX- and NYSE-listed Endeavour produced 1.43-million ounces of silver and 12 968 oz of gold, resulting in silver equivalent production of 2.4-million ounces. Compared with the third quarter of 2017, silver production was up 13% and gold production fell by 5%. Silver-equivalent output improved by 5%. The silver-equivalent production increased on the back of significantly improved silver and gold grades at El Cubo being mined from the centre of the Villalpando-Asuncion orebody.
