Cerro Blanco

JDS completed NI 43-101 compliant Preliminary Economic Assessment (2017) and Feasibility Study (2019) for Bluestone Resources' Cerro Blanco Project in Guatemala. The studies demonstrated a rapid payback, high-margin underground gold-silver mining project with robust economics and $196M pre-production capex. JDS managed four engineering sub-consultants and three lab test programs, completed mine/process design, project economics, and delivered the FS report within 7 months of receiving the final resource block model. Both projects were delivered on schedule and on budget.
