"Ondiamondswebuild." The slogan is impressive in Namdeb's brochure. Although the first thing that comes to mind when it comes to diamonds is South Africa, and several famous diamonds in the world come from South Africa, Namibia, the world's largest diamond mine, is the real diamond kingdom. There is a "Diamond Coast" with proven reserves of over 50 million tons of onshore diamond ore, the purest diamonds of which 95% are gemstones and the best diamonds in the world, The world's largest producer of diamond jewelry, diamond output ranks fifth in the world. Namdeb is Namibia's largest diamond producer, known as Namdeb Diamond Corporation (Pty) Limited, which owns half of the stake in Namibian government and the other half is owned by De Beers Centenary AG, the world's largest diamond company, Former Consolidated Diamond Mines (CDM) was a wholly owned subsidiary of De Beers until 1994. The existing diamond mines in Namibia are mainly located in the southern and southern seasides and offshore areas. Land mines are mainly: "1 Mining Area", "Orange River", "Elizabeth Bay Mine"; the main sea areas are: "Atlantic 1 Permit Zone", located in Luderitzi Bay "Koichab offshore mining area" The Marshall Fork offshore mine and the Diaz offshore mine. In addition to the three smaller offshore mines Koichab, Marshall Fork and Diaz above, all other diamond mines are owned by Namdeb. 70% of the Atlantic Permit Zone is owned by Beers and 30% is owned by Namdeb. In 2001, total national diamond production was 1.49 million carats, of which 93% were diamonds produced by mines owned by Namdeb. According to the company's report, as of the end of 2000, its owned (onshore and offshore) mines retained resources and reserves as follows: a rough reserve of 59.4 million tonnes at a grade of 1.5 cpht and an estimated 73.6 million tonnes of resources 2.3 cpht, presumably 301.7 million tons of resources, grade 1.5 cpht. In terms of contribution to GDP, the mining industry contributes about 10-12% of GDP annually. In 2003, the sagezinc mine has commenced operation and its smelter will be operating at full capacity to increase the percentage by another 4%. The amount of diamond mining will also continue to increase, and mining contribution to the national economy will remain at this level for a future period; minerals are the dominant exporters of Namibian exports while diamonds and other minerals are at The proportion of exports is also constantly changing. In 1990, diamonds accounted for only 40% of all mineral exports, up from 91% in 1999. In all export exchange, mineral exports increased to 40%; in the tax revenue of the central government, the tax revenue directly from the mining occupies an important position. Since independence, taxes from mining companies have accounted for 30-50% of all taxes. If other taxes on export diamonds are taken into account, an additional 10% will be added; in employment, employment in the mining industry dropped from 8% in the 1980s to 1997 due to new equipment and technology 2%, the industry is still a larger employment industry. "Namibia's diamonds generate 40% of foreign exchange earnings, 7% of government revenue and more than 10% of GDP." Namdeb's marketing materials also include such a figure. Now, in Namibia, diamonds have become part of so many Namibian lives. Diamonds play a major role not only in Namibian economy, but also in their society. Namdeb has been investing in education for many years, not only in company-wide training programs, but also in building training institutes and secondary schools across the country. Many of Namibia's professionals have been trained in the diamond industry and brought their expertise to other fields, thus benefiting the overall economy.
