Campo Morado Mine
JDS led design and construction of the Naranjo Alto tailings facility for Nyrstar with a $32M budget, one-year timeline, and 900,000 m³ earthworks including HDPE liner installation. JDS procured and mentored local contractors to achieve budget and schedule targets. Following a project design review, JDS managed staging optimization that reduced initial capital costs to $6.2M by lowering initial elevation and limiting liner to the downstream face only. JDS also managed an expansion raise lift to the existing tailings pond. All work was completed under budget and on schedule.
