This comes from a recent Namibia mining report that you can buy for $500 US. Or you can read the summary here.
In May 2009, there were fresh media reports that Namibia is thinking of following the lead of South Africa and introducing a mining charter, designed to increase black ownership of mineral assets. South Africa's legislation, introduced in 2004, compelled mining companies to sell a 15% stake in mining assets to local black investors by 2009, rising to 26% by 2014.
