CLIENT: Pueblo Viejo Dominicana Corporation (PVDC)
LOCATION: Central Dominican Republic
The Pueblo Viejo Mine located in the central Dominican Republic recommenced gold production in 2013. Although modern-day mining efforts were initiated in 1975, mine reconstruction was undertaken in 2009 with capital expenditures totaling $3.7 billion.
BGC has provided engineering services to the Pueblo Viejo Project since 2001 with work spanning from due diligence review through prefeasibility, feasibility, construction, and operations. We have been an integral team member, working with Placer Dome, Barrick and various stakeholders to ensure the work is carried out safely and responsibly.
The site is in a high seismic and high rainfall area in a geologic setting comprised of saprolite, complex metavolcanics, and karstic limestone. Work fronts have included tailings dam design and hydrogeology, foundation design for the plant site, landslide investigation and remediation, transmission line routing and reclamation of historical mining facilities.
A major focus of BGC’s involvement on the project has been as the Engineer of Record for the newly commissioned tailings and waste storage facility. The tailings facility comprises several zoned earthfill tailings dams, one of which will reach an ultimate height of 140 m. BGC conducted a number of studies related to the tailings facility, including:
