  3. In 1999, AngloGold acquired the mine through a takeover of Acacia Resources Ltd, a move that gained it a 33% stake in the Boddington project. Navachab Gold Mine is a subsidiary of Anglogold Namibia. One of the complexes is shown in one of the earliest known maps, the miners crushed the ore and ground it to a fine powder before washing the powder for the gold dust 8.
  4. The deposit is located 6 km south of the - road. It envisaged that an increase in the milling to 840 000 tones per annum may be possible which will allow a decrease in the planned head feed grade.
  5. Dausab testified in support of his case. Originally jointly owned by the Erongo Exploration and Mining Company 70% , the Metal Mining Company of Canada 20% and Rand Mines Exploration, acquired a 70% interest in the mine in 1998, which it increased to a 100% the following year. It is this principle that the court in Rumingo endorsed, and it echoes the approach adopted by appellate courts in many different jurisdictions. Maharero and his sons, Jan Jonker Afrikaner, Hosea Kutako and it stood at just over 14,000 as measured by the 2001 Population and Housing Census, and is estimated to have surpassed 24,000 in 2012. The current open cut operation dates back to 1995, the operation became part of AngloGold in March 1999, when the company acquired the Independence Mining Company and thereby 66% of the mine. An appraisal was carried in 1986 and followed by feasibility study in 1987, after which a decision was made to proceed with the development of a mine.
  6. Slurry pumps push the boundaries of reliability - A haul road is situated at the side of the pit, forming a ramp up which trucks can drive, carrying ore.
  7. Navachab gold mine Karibib Namibia Navachab gold mine Information on the only gold mine in Namibia. The first gold-bearing quartz veins in Namibia were discovered in the Rehoboth district in Sinclair sequence volcanogenic host rock as early as 1899. During the pegging boom of 1933 and 1934 many prospects opened up and exploited, but all were later closed down, mainly due to the low and erratic grade of the mineralisation. Most recently, Namibia gold production received a new boost. The Navachab gold deposit was discovered as a result of a geochemical exploration program in October 1984, during exploration for carbonate-hosted gold deposits area. It was discovered on the farm Navachab, 6 km south of the main Okahandja-Swakopmund tar road. An appraisal was carried in 1986 and followed by feasibility study in 1987, after which a decision was made to proceed with the development of a mine. Construction work began in 1988 and the first gold bar was poured only 21 month later in December 1989, establishing Namibia as one of the gold producing countries in the world. The mine was completed at a capital cost of 85 million. The plant was commissioned in November, with full production being achieved in January 1990. The 35 metre-thick ore body is hosted in a thick marble unit. The ore body dips at 70' to the west and plunges at 14' to the north and it is mined by open-cast method to a depth of 160 metres. The ore body is estimated to contain 10. It will approximately take 13 years to mine and process these known reserves. It envisaged that an increase in the milling to 840 000 tones per annum may be possible which will allow a decrease navachab gold mine the planned head feed grade. The carbon-in-pulp process recovers 85% of gold. Pink nosib formation quartzites and arkose occur on the eastern edge of the mining area and are overlain by other formation mixtures. The marble-hosted gold skarn mineralisation is related to multistage mineralisation, from 800 metres north-east of the main ore body, greisen and pegmatite's are localised around a late stage, fluorite which is interpreted to be possible heat source for the final concentration of low grade gold deposits. This zone hosts the bulk of gold mineralisation, 2 the hanging wall banded grey marble and melted dolomites. This zone hosts navachab gold mine vein storkwork style ore body of limited tonnage. The possibility of upgrading the marginal ore reserves using dense medium separation d. Gold discoveries of 60% to 81% were achieved at a concentrate grade of 3 to 4 grams of gold per ton. The alternative of increasing plant milling capacity is now being investigated. The resultant plant throughout would lead to scale economics and lower grade material could then become profitable. An input exploration program during 1992 give a better definition of part of the ore body which lead to the redesign of the open pit. With this exercise it was found that the ore body can be economically mined to a depth of 190 metres compare to the original depth of 160 metres. Diamond drilling during the last three years indicate extensive strike extensions to the ore body and it is still open ended at 600 metres north of the planned open pit. With 14 plunge to the ore body it is not possible to mine extensions navachab gold mine open-cast methods.
