In Africa, settlers and colonists often called something a “discovery” when local people had known it for centuries. Johannesburg was no different.
We know now that Tswana speaking people had inhabited this ridge for centuries before the first prospector set foot on it. Old diggings and smelters have since been discovered. Missionaries passing through in the 1860s wrote of indigenous tales of gold as if it were legend. The riches beneath their feet were hidden only from those who would lay claim to everything as their own find.
The Struben brothers had been prospecting the ridge since September 1884. They assembled a stamp battery at Wilgespruit, twelve kilometres from where the Main Reef would be found. They were processing rock from the wrong formation. Nothing followed.
George Harrison came to Langlaagte looking for work and found it as a builder. Then he broke open a piece of banket conglomerate. In his affidavit of 24 July 1886, he wrote: “I have long experience as an Australian gold digger and I think it a payable goldfield.” That was his authority.
The Transvaal Government proclaimed the goldfields on 8 September 1886. Within weeks, 3,000 people were on the site.
Johannesburg was proclaimed in October 1886 and grew to 102,000 within six years. The basin has yielded more than 50,000 tonnes of gold — somewhere between a quarter and 40% of all the gold the world has ever mined, from a single ridge. More than that still sits underground. After 140 years, the Witwatersrand is not yet half empty.
One man who did stay: Col. Ignatius Ferreira, who had chased diamonds at Kimberley and gold at Barberton without finding either, viewed Harrison’s outcrop, and built the first organised camp on the ridge. That camp became Ferreirasdorp. The oldest suburb of Johannesburg.
Harrison sold his Discoverer’s Claim on 16 November 1886 for £10. He was not seen on the Witwatersrand again. He was not heard of anywhere else either. He told someone he was heading to Barberton. After that, nothing.
The cyanide process arrived in 1890 and saved the field. Capital organised. The city was built.
In March 2026, South Africa poured first gold from its first new underground gold mine in 15 years. The mine is called Qala Shallows, owned by West Wits Mining, on the same goldfield Harrison found. Qala is a Zulu word. It means to begin. Nobody knows the exact date Harrison made his find. The 140th year is 2026. Qala Shallows opened in it.
Harrison’s name is on a park in Johannesburg. Most people drive past it without stopping.
George Harrison disappears from the record after November of 1886. 140 years later, in 2026, his field opened a new mine.
