Escobal Mine On-Site Services

Project Overview

The Escobal project is a high-grade silver deposit, located in Guatemala, approximately 70 km southeast of Guatemala City by paved road. The Escobal resource includes an Indicated silver of 368M ounces at 422 g/t average grade, and an Inferred silver resource of 36.7 million ounces at 254 g/t average grade. Capital cost for the 4,500tpd underground mine and milling operation amounts to $400M. Commercial production was announced in 1Q 2014 on schedule. Exploration drill programs are ongoing which continue to expand known mineralization.


Project Scope

Upon startup of the plant in 2014, JDS provided operational support to three tailings 3,500tpd filter presses which supply dry material for dry stack tailings and to the underground past plant; as well as operational oversight on the operation of the dry stack tailings placement and paste plant operation.

JDS was also retained to undertake two critical sustaining capital expansion projects to support the operating business plan. JDS provided EPCM services for a new 1,500tpd tailings filter press and past plant installation, for the installation of a 210m3/hr capacity paste plant.

JDS was responsible for ensuring that these critical sustaining capital projects were on schedule and on budget.
