“Having started trial mining at Silverstreams in July last year, our progress on the project has been excellent despite the fact that Eskom failed to hook us up to the power grid until January this year. We faced the challenge of having to operate on diesel at a cost of around R1 million a month, whereas operating cost on Eskom power amounts to only R200,000 a month."


The company’s pipeline of advanced alluvial and kimberlite exploration projects in the DRC includes its key Kwango River and Tshikapa initiatives.
