The mainstay of the economy of North West Province is mining, which generates more than half of the province's gross domestic product and provides jobs for a quarter of its workforce. The chief minerals are gold, mined at Orkney and Klerksdorp; uranium, mined at Klerksdorp; platinum, mined at Rustenburg and Brits; and diamonds, mined at Lichtenburg, Christiana, and Bloemhof. The eastern and southe
rn parts are crop-growing regions that produce maize (corn), sunflowers, to***co, cotton, and citrus fruits. The entertainment and casino complex at Sun City and Lost City also contributes to the provincial economy.
