Golden Ridge – Akyem (Ghana)

The successful completion of the 157Ha Tailing Storage Facility, including the bulk and detailed earthworks, was achieved at the end of May 2013, after 25 months of construction in the warm African sun.

The completed scope of work included 1,511,000m² of HDPE liner, 1,531,000m² of soil liner, over 1,000,000m³ of topsoil stripped and a design cut and fill volume of over 6,000,000m³. We also constructed an 8km access road and HDPE pipeline. All of these activities were successfully achieved with more than 2.5 million LTIF hours.

We are currently busy with the construction of the Pit diversion channel which involves 450,000m³ of excavation mainly in hard rock, over a length of 780 lineal meters. At it's deepest, the channel invert level is deeper than 33 meters below natural ground level.
