TRANSFORMATION
The goal of this rehabilitation work was to transform a 4.4-hectare piece of land on CBM’s 6.13-hectare Olalondo pit site into an agricultural area, as well as blend the site with its surrounding environment. Work began in November 2018 with the preparation of the site floor to allow for better drainage and infiltration. In total, 50,000 cubic metres of overburden material was distributed, 12,500 cubic metres of which was applied to the west side slope, 15,000 cubic metres for the north side slope, and 22,500 cubic metres for the pit floor.
Agriculture Objectives
After the overburden was shaped and contoured to plan, 50,000 cubic metres of topsoil was applied to a minimum average thickness of 250 mm. Finally, a 490kg seed mix of alfalfa, red clover, perennial ryegrass, tall fescue, and timothy was applied to boost soil quality and facilitate the site’s agricultural objectives. Rehabilitation work concluded in April 2019 with row crop production scheduled for 2020.
