Motsepe had raised the funds through the Broad-based Economic Empowerment Trust for education, health, welfare and other community upliftment projects.
"One of my objectives is to give back, particularly to communities on whose land I make money," Motsepe told The Sowetan.
"While it is not possible to feed all starving communities in the country, I am glad that I make changes where I can. That is one of my objectives."
Some notable beneficiaries include Cosatu, Sadtu, Nehawu and the Zion Christian Church.
