Gold recovery and clean-up go hand in hand at Mogale sites Local mining and rawmaterial processing firm Ncamiso has joined forces with Mintails Mining SA-Mogale Gold to carry out vital services in order to ensure maximum gold recovery as well as environmental remediation. “In each of the Mogale gold projects that Ncamiso has taken on, we will be helping to increase their revenue through the recovery of gold from the areas we are working on as part of overall land rehabilitation efforts,” says Ncamiso’s MD, Fikile Mashinini.

A ccording to Mashinini, the proj- ects “fill our dedication to CSI by also providing jobs as reef pickers to those in the immedi- ate communities that we oper- ate in. Furthermore, by cleaning up and reha- bilitating the land we assist in the eradication of illegal miners in the areas.” The work being carried out by Ncamiso at various Mogale Gold sites includes the following:  DRD cluster: cleaning out of the old reduction plant and removal of contaminated surface material so that Blue Print Developments is able to build low-cost houses.  Goudrand: removal of contaminated surface material to rehabilitate the ground for Blue Print Developments.  Kimberley Reef: shallow opencast mining to remove gold-bearing conglomerates close to the surface (that would otherwise be steril- ised) so that the soft underlying layers of reef can be removed to prepare the land for use as a recreational park.  Sub-Nigel: screening out fine materials and reef from Afrisam’s waste rock, which can then be used to produce building materials.  Springs Market: rehabilitating an old reduc- tion plant on a farm belonging to Markon Realty for future use in hydroponic fish farm- ing and industrial development. At all the sites, the fine materials are sent to Mogale Gold for gold processing. On a day to day basis, Ncamiso is respon- sible for delivering material loaded and hauled from the abovementioned sites. It handles on- site sampling of delivered material, screening at -20 mm and loading of material onto the conveyor belts which make the transfer to the relevant processing plants. To date, says the company, more than 200 kg of gold has already been recovered from 200 000 tonnes of material delivered to Mogale Gold, and a total of more

than 500 kg from than 1 Mt to various mines – a very high yield for surface mining. Mintails Mining SA’s CFO, Eddie Milne, says that Ncamiso’s services have always been effi- cient. “Their employees display an open and honest persona and their work ethic is excep- tional,” he says. “Ncamiso has been open and transparent in its dealings with Mintails, acting as partners in the various projects, sharing both the benefits and the struggles. Ncamiso adds value to our business and we will continue to partner with them in the future.” The environmental remediation being car- ried out by Ncamiso and Mogale Gold reduces the state’s liability for the number of waste dumps that need to be rehabilitated and repro- cessed. “The joint projects with Mogale Gold help both parties to build and strengthen the relationships between the mine and non-mine stakeholders. Mintails Mining SA-Mogale Gold and Ncamiso are establishing their reputation as companies invested in the sustainability and upliftment of the communities they work in,” says Milne. 
