In 2001, an archaeologist named Zoe Henderson was reworking old mine dumps at Koffiefontein when she uncovered three skeletons. As excavation continued, three became thirty-six, and thirty-six proved to be only the edge of a graveyard. The bodies belonged to miners, most of them young men between twenty-five and thirty-three, buried in hessian wrappings with copper bangles and traditional beads still around their necks. They had died in 1896, during a typhoid epidemic that killed roughly seven people a week for months, and the mining company had buried them in its own waste rock because there were too many dead to dig proper graves. Koffiefontein produced some of the finest diamonds in South Africa. It also produced one of the starkest records of what that brilliance cost the people who extracted it.
The Koffiefontein pipe was discovered in 1870, one of many kimberlite deposits clustered around what would become the diamond capital of the world. Located about eighty kilometers from Kimberley in the Free State province, it was never the most productive mine. Its yield ran four to five carats per hundred loads, modest by the standards of the Big Hole. But what Koffiefontein lacked in volume, it compensated in quality. Edwin Streeter, the Victorian-era gem authority, singled out Koffiefontein and neighboring Jagersfontein as producing diamonds of "the first water," the highest grade of clarity.
Over its full lifetime, the mine yielded 7.3 million carats, its largest stone a 139-carat gem. Twelve hundred and forty-three claims were staked in 1878. By 1893, Alfred Mosely had consolidated many of them into The Koffyfontein Mines Ltd, headquartered in London. De Beers acquired the operation in 1911 and held it until 2006, when Petra Diamonds took over.
The miners at Koffiefontein came mostly from the Transvaal and the Eastern Cape, recruited by agents in rural areas and housed in compounds with strict regulations. Wages were low. The men fed themselves, and most sent whatever money they could spare back to families in their homelands, leaving little for their own nutrition. Sanitation in the compounds was poor. These conditions created a perfect incubator for disease.
In February 1896, an enteric fever broke out. By May, more than two hundred miners were sick and forty were hospitalized. The epidemic ground on through the winter, killing approximately seven people every week. On one particularly devastating day, according to the weekly letters that mine manager Walter Stanley Whitworth sent to London, roughly thirty workers died. The overwhelmed mine buried bodies in shallow graves and then covered them with tailings from the washing operations. A letter from the Secretary of the London and Orange Free State Exploration Company to the Free State government, dated 20 May 1896, asked the government to stop the practice. The miners were eventually diagnosed with typhoid, traced to a contaminated water reservoir in the town.
When Henderson's archaeological team began excavating in 2001, they found five poorly aligned rows of graves in the oldest mine dump, the Whitworth Dump on the eastern side of the open pit. The dump was composed entirely of "yellow ground," the decayed kimberlite from the top twenty-one meters of the pipe, mined until 1902 to reach the harder blue ground beneath.
The burials did not follow the traditional African practice of wrapping the deceased in a mat or skin in a seated position with knees drawn to the chest. Instead, the bodies lay in varying orientations, some wrapped in plain hessian, some in red-stained hessian, a few in blankets. Cultural materials survived with them: buttons, metal arm bangles, iron leg bangles, coiled copper-wire bands, and strings of traditional beads. Of thirty-six excavated skeletons, thirty-three were male and two female. The average age at death fell between twenty-five and thirty-three. After the thirty-sixth skeleton, the mine halted operations and left the rest of the graveyard undisturbed. The unexcavated portion extends eastward toward the dump's edge, its full extent unknown.
The typhoid epidemic and the conditions that produced it bred more than illness. Dissatisfaction grew among the surviving miners, eventually erupting in an attempt to escape the living compounds. During the resulting unrest, one mineworker was shot and later died from his wounds. The violence at Koffiefontein was part of a broader pattern: between 1913 and 1914, miners' strikes swept through Koffiefontein, Jagersfontein, Kimberley, and other diamond operations, driven by grievances over pass laws, compound conditions, and the devastating drought that was starving families in Basotholand.
Whitworth himself presents a complicated legacy. He arrived as a civil engineer in 1896, intending to stay two years to build the railway. He remained for over sixty years, becoming a central figure in Koffiefontein's development. His weekly letters to London, maintained for four decades, provide the most detailed record of life at the mine, including the grim accounting of the epidemic. The dump where the dead were buried still bears his name.
Behind the mine manager's house, a rocky outcrop called a koppie holds four rock engravings. Two at the base depict a black wildebeest and a warthog. Two near the summit show eland. These are the work of San people, created during religious trance states as expressions of spiritual experience. The engravings likely predate the mine by centuries, perhaps millennia, placing them in the same artistic tradition found at Nooitgedacht and Driekops Eiland elsewhere in the region.
The mine's guard house, over a century old, is protected under South Africa's National Heritage Resources Act. It served as a military structure during the Second World War, when the area functioned as an internment site. From diamonds to disease to war to ancient art, Koffiefontein layers its histories on top of one another. The koppie's eland watch over the mine dumps from their perch on the rock, silent witnesses to everything that followed their creation.
Located at 29.40S, 25.02E in the Free State province, approximately 80 km southeast of Kimberley, South Africa. The mine appears from the air as a large open pit surrounded by tailings dumps and scattered infrastructure. The town of Koffiefontein sits adjacent to the mine. Nearest major airport is Kimberley Airport (FAKM), about 80 km to the northwest. Bloemfontein Airport (FABL) is approximately 150 km to the east. The terrain is flat Free State grassland, dry and brown for much of the year. The mine pit and pale tailings dumps contrast sharply with the surrounding landscape. Recommended viewing altitude: 3,000-5,000 feet AGL for detail of the mine workings and town layout.
