runs an annual Copper Festival. The Tsumeb mine operated from 1907 to 1996, extracting copper, lead, zinc, gold, germanium and cadmium. Uis was established in 1958 as workers' settlement to exploit local tin deposits. Mining started in 1960 and grew to be the world's largest open cast tin mine. Yield was very low, and the mine was sustainable only because South Africa was economically isolated due to its apartheid politics. When sanctions were lifted in 1990, the Uis mine was no longer viable. In the 2010s investments and work started again at the old mine.

Legal framework Related to the mining industry, the main legislation is the Minerals (Prospecting and Mining) Act 33 of 1992 (Minerals Act). In the terms of this act, owners of the land don't have mining rights because natural resources belong to the state. For getting the right prospect or mine an area, a mining license or a mining claim is required, provided by the Minister of Mines and Energy of Namibia. Namibia’s mining industry is regulated by the Diamond Act, 1999; the Minerals (Prospecting and Mining) Act, 1992; and the Minerals Development Fund of Namibia Act of 1996. The petroleum sector is governed by the Petroleum (Exploration and Production) Act, 1991; the Petroleum (Taxation) Act, 1991; the Petroleum (Exploration and Production) Amendment Act, 1993; the Petroleum Laws Amendment Act, 1998; the Model Petroleum Agreement, 1998; and the Petroleum Products and Energy Amendment Act, 2000. In 2006, the Government confirmed a royalty schedule that originally had been introduced in 2004. A 3% royalty was levied on the market value of base, precious, and rare metals and nonnuclear mineral fuels. A 2% royalty was levied on industrial minerals and nuclear mineral fuels. In Namibia, mining legislation is under revision. According to the Intergovernmental Forum on Mining, Minerals, Metals, and Sustainable Development (IGF), Namibia counts with a strong regulation around the development of environmental impact assessments
