R450 bln gold Master’s research elevated to PhD
In what potentially is the world’s largest invisible gold resource Dr Steve Chingwaru’s findings could help unlock gold valued at R450 billion within the unsightly mine dumps around Johannesburg
THE grandson of George Nolan, a renowned prospector who discovered lithium in Zimbabwe then southern Rhodesia has also made history after his Master’s degree research that is aimed to calculate and characterise gold reserves, was upgraded to a PhD.
In what potentially is the world’s largest invisible gold resource Dr Steve Chingwaru’s findings could help unlock gold valued at R450 billion within the unsightly mine dumps around Johannesburg.
The 26-year old PhD recipient’s trailblazing research in geomatallurgy is has drawn interest globally.
According to a report by The Zimbabwe Mail, the Stellenbosch University student is the first scholar to calculate that the six billion tons of tailings around Johannesburg’s mines contain up to 460 tonnes of gold.
He has also discovered ways to extract the gold efficiently while addressing environmental concerns related to the tailings, such as the release of acid mine drainage due to pyrite oxidation.
“Historically, the low concentration of gold inside tailings was considered too low grade to be of value. But now that extensive mining has depleted most of the high-grade concentration of gold, it’s becoming unfeasible to mine – some shafts are already reaching 4 km underground. Looking for gold in low-concentration sources is becoming more viable,” Chingwaru notes.
Some big mining companies have started to process the tailings to extract the leftover gold, but the traditional way of extraction through cyanide is not very effective and also damaging to the environment, Chingwaru points out.
“Typically, they manage to extract just 30% of the gold through this process. So, in my PhD research, I asked where the remaining 70% is and how it can be safely removed from the pyrite.”

Govt, Zanu PF issues Icarus-fate warning to motormouth Wicknell Chivayo
ASPIRING billionaire Wicknell Chivayo appears to have dug his own grave, less than a month after his company was awarded a lucrative Starlink deal to be the sole provider of in Zimbabwe
Reacting to a viral audio leaked recently were Chivayo bragged that the President was under his wings, government and Zanu PF spokespersons have issued a veiled warning to Chivayo against flying too close to the sun, by abusing his proximity to President Emmerson Mnangagwa.
In separate posts on X Nick Mangwana and Farai Marapira said Chivayo was forgetting that he was a nonentity in the political matrix of this country.
Mangwana said like Icarus Chivayo was flying too close to the sun, had quickly forgotten that his wings were made from wax which would easily melt.
“Icarus was warned by his father not to fly too close to the sun, as the wax that his wings were made from would melt. But fueled by the adrenaline rush of flying , Icarus failed to rein in his excitement and felt he was the man of the moment. He did not heed the warnings, Icarus was so intoxicated by the experience of flying and never thought he could tumble from this loft height, so he flew higher and higher getting closer and closer to the sun. The closer he came to the sun, the more the wax in his wings melted. He tumbled into the sea and drowned,” said Mangwana.
Zanu PF spokesperson Farai Muroiwa Marapira weighed in saying pride comes before a fall.
