Our mining division operates in Kenya and Zimbabwe, with production set to rise sharply.


The success of any mining project depends on a mutually-beneficial relationship with our local communities and our strategy is guided by the highest international regulations, including the IFC Performance Standards on measuring, mitigating and reporting environmental and social impact.


Maris mines have hubs for technical training and have brought roads, water, power, clinics and schools to their local areas.


We specialise in turning around high-grade, stranded gold assets, which have high-profit potential but are too small for larger mining companies.

Commoner Mine

80% ownership

In 2013, in partnership with managing director David May, Maris invested in a group of 32 mining blocks covering 5 mines, which had laid dormant since the 1980’s: Bee Mine, Bee Eater Mine, Pamela Mine, Commoner Mine and Welcome Back Mine. The largest mine, Commoner, produced over 4 tonnes of gold during its working lifetime. We have rehabilitated the infrastructure and an open pit mining operation has re-commenced.
