Our team identified the key study milestones as being the completion of the basis of design criteria set; options analysis, non mine landform MTO production, estimate, engineering services deliverables, review and development of the Order of Magnitude study report.
The project was unique as the closure requires a progressive rehabilitation. The six mine pits will be progressively closed such that the pit floors are rehabilitated and access to rehabilitated areas is restricted to prevent inadvertent trafficking post rehabilitation.
Operations will continue producing low grade stockpile while Calibre QuadR rehabilitates the mine pits that have been exhausted.
The original project scope was a partial closure of site. After a series of reviews and the Life of Mine Ore Body Effectiveness Study, the client decided to continue operations at the site. The delivery strategy changed from partial closure to progressive rehabilitation once the pit and low-grade stockpiles are exhausted.
Calibre QuadR coordinated and managed engineering works and collated results for developing the master order of magnitude report, estimate and schedules. Our team was accountable for delivering engineering services for:
