Mining is the biggest contributor to Namibia's economy in terms of revenue. It accounts for 25% of the country's income. Its contribution to the gross domestic product (10.4% in 2009, 8.5% in 2010, 9.5% in 2011, 12.3% in 2012, 13.2% in 2013, 11.6% in 2014) is also very important and makes it one of the largest economic sectors of the country. The majority of revenue (7.2% of GDP in 2011) comes from diamond mining.
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.
Epangelo Mining is a mining company owned by the government. It was founded in 2009 with the aim to govern the rights on six mineral resources that are deemed strategic for Namibia, and for which new exploration rights must be held by government. The six resources are: diamonds, gold, coal, uranium, copper, and rare earth minerals.
In 2006, manganese, diamond, and fluorspar output increased by 158%, 24%, and 15%, respectively, compared with that of 2005, and copper, lead, wollastonite, and zinc posted significant production declines. The increase in manganese was attributable to the expansion of production at the reopened Purity Mine (formerly the Otjisondu Mine). The decline in copper output could be attributed in part to instability during the transition of ownership of Ongopolo Mining and Processing Ltd. Lead and zinc output declined in part because of a short strike by workers at the Rosh Pinah mine.
