Newlands Diamond Mine:
Newlands Diamond mine is situated 55km Northwest of the small town of Barkly West in the Northern Cape province in the Republic of South Africa
Newlands is a Group 2 kimberlite complex which was discovered in the early 1880s and mined between 1903 and 1918 and again from 1956 to 1959. A total of only about 6500 carats were produced at an average grade of 7.5cpht.
The blows have been worked sporadically since the late 1980s and Newlands’ blows were mined underground via shaft mining up until the early 2000s.
Newlands is an open-cast operation, producing an average of 500tons of ROM per day.
Newlands is one of a number of kimberlite intrusions, both small pipes and fissures in a broad belt which includes the Belisbank group. Newlands Kimberlite is dated at 114 Ma. The Kimberlite was abundant Olivine, Phlogopite, Garnets and up to 35% of Xenoliths.
Blaauwbosch Diamond Mine:
Blaauwboch Diamond mine is situated 23km East of the small town of Boshof in the Free State province - 75km east-north-east of Kimberley, Northern Cape Province in the Republic of South Africa.
Blaauwboshch is a Group 2 kimberlite comprising of a relatively large pipe and a well-developed fissure which extends both north and south of the pipe.
Historically, Blaauwbosch was the 19th largest producing kimberlite pipe and was mined to a depth of about 110m producing 967,000t of ore, yielding 338 carats of a grade of 35 cpht. After flooding in 1967, operations were ceased. The mines reopened in 2004 with the resumption of production. However, tailings were processed since 2003. In 2005 production was halted to undertake plant redesign, shaft deepening and underground development.
The shaft was sunk to a depth of 185m and it allowed the shaft to reach 220m underground. This was done to allow for development in a deeper block of kimberlite ore.
The Kimberlite is underlain by flat-lying shale, siltstones and mudstones of the Ecca Group of the lower Karoo Supergroup.
The Blaauwbosch Kimberlites comprise of a small pipe, at least one fissure and a blow or fissure. These intrude into the flat-lying shales of the Dwyka Formation. These are about 180m thick.
The Kimberlite consists of fine-grained micaceous matrix crowded with shale, lava and occasionally granite-gneiss xenoliths and a green-streaked pink rock with abundant secondary epidote.
New Elands Diamond Mine:
New Elands Diamond mine is located on the remaining extent of the farm New Elands, 90km northeast of Kimberley in the Boshof district of the Free State Province in the Republic of South Africa.
Historically, New Elands produced 1.5 million tons from dykes and blows, yielding approx 464,000 carats at 34 cpht. New Elands consist of a kimberlite dyke with two small blows and has operated intermittently since 1912. Currently, New Elands is dormant.
Nooitgedacht Alluvial Diamond Mine:
Nooitgedacht Alluvial Diamond mine is situated 15km northwest of Kimberley in the Northern Cape Province, South Africa. The farm, Nooitgedacht, extends 6km along the eastern bank of the Vaal river and covers 4,671 hectares.
Between the 1940s and the 1980s, a small portion of Nooitgedacht was minded by diggers. During this period historical records note that some 76,000 carats were discovered in total. The largest diamond found during this period was the Venter Diamond, a yellow stone that weighed 511 Carats.
The discovery of the Venter was one of the biggest alluvial diamonds found in South Africa, and the diamond rush resulted in the recovery of another two +300 carat diamonds. In total 14 diamonds, weighing more than 100 carats, have been recovered from Nooitgedacht.
Nooitgedacht is part of the diamondiferous gravel runs of the Vaal and Hartsriver valleys in the Barkly West area. They are considered to belong to the overall diamond train associated with an old geological feature known as the Kaap Valley.
