Umsimbithi Mining currently has one operation called Wonderfontein Colliery. Wonderfontein Colliery is the first mine owned and managed by Umsimbithi Mining which started its mining operations in 2012 as an underground mine but converted to a 100% opencast truck and shovel operation by the end of 2013.

Wonderfontein Colliery has a processing plant with the design capacity to process 300kt of coal per month and a railway siding capable of handling RBCT jumbo size wagons. Umsimbithi has 500ktpa throughput allocation at Richard’s Bay Coal Terminal. The majority of activities are outsourced and the mine currently employs, directly or through the contractors, over 800 people
