Mining in Gauteng
No piece of ground has shaped South African mining like the gold arc beneath this province. Johannesburg rose on it, and an entire industry followed. A century and a half later the reef is far from finished: AMIQ counts 26 live projects here, taking in Witwatersrand gold worked far underground, coal where the province meets the Highveld, and the Cullinan diamond operation outside Pretoria. In the cradle of the trade, the supplier who knows the operators by name keeps winning the contract before anyone else hears of it.
26 live Gauteng projects on the AMIQ map of South Africa
The commodities still worked across Gauteng
Gold sits at the centre of it all, drawn out of the deep Witwatersrand basin that made this the richest mining province in the country, with coal worked where Gauteng touches the Highveld and the Cullinan diamond operation just beyond Pretoria. No two of these minerals call on the same trades, and AMIQ keeps the live projects behind each of them within reach.
Everything here still turns on the Witwatersrand basin. Operations like the Mponeng depth extension, Blyvoor and Qala Shallows chase the ore thousands of metres beneath the surface, working the most valuable gold-bearing ground ever discovered.
Explore → COut east, along the seam where the province runs into the Highveld coalfields, a handful of coal mines supply electricity generation and heavy industry. They give bulk-handling, earthmoving and haulage firms a reliable run of work.
Explore →Just outside Pretoria, Petra Diamonds works the Cullinan kimberlite pipe, perhaps the best known in the world and the place the largest gem diamond ever recovered came from. Its block-cave mine below ground sustains years of steady engineering demand.
Explore →The dumps left behind by a hundred years of gold mining now hold value of their own, and recovering it has become a business in its own right. Ergo and DRDGold pull fresh gold from those old residues, with steady demand for pumping, plant and processing kit.
Harmony Gold, Sibanye-Stillwater, DRDGold and Petra Diamonds hold the marquee operations on the province's gold, retreatment and diamond ground. Whatever these operators choose to build and order sets the rhythm for every supplier chasing Gauteng work.

Sign up to AMIQ and all 26 live Gauteng projects open up, each one listing the checked mine-owner, engineer and EPC contacts, putting you in touch with the buyers before any shortlist closes.
How Gauteng's 26 projects divide by mineral
Gold takes the largest share of the pipeline, lifted from the deep Witwatersrand reef, followed by coal in the east, a cluster of industrial mineral and aggregate sites, the single Cullinan diamond operation and a modest fluorspar holding. The split below sets it out, and behind each entry a supplier finds the site location, the phase it has reached, the owner and the checked contacts that turn a lead into a quote.
How AMIQ gets suppliers to Gauteng mines first
Deep gold shafts, retreatment plants and the Cullinan pipe each sit on top of a long line of suppliers, and it is usually the service providers who reach a project early that end up dictating the terms. Drill, engineer, test, process, hire out equipment or move freight: it all starts with seeing which sites are live and knowing who controls the budget.
Find a project before the spec is locked. Filter by scope, stage and location to bring up Gauteng sites while the requirements are still being settled, long before any of it reaches a public tender.
Go straight past the gatekeepers. Names come attached to every entry, the owner of the mine, whoever engineers it, the EPC house and the firms already supplying it, all confirmed and refreshed by our researchers rather than scraped from the open web.
Hear of every move the day it happens. The moment a new Gauteng site is logged, or one you already follow shifts phase, a text or an email lands with you, so nothing quietly slides past while you are looking elsewhere.
Coverage that follows the gold. Deep Witwatersrand shafts, the retreatment dumps, the eastern coal seam and the Cullinan pipe past Pretoria all sit on the map, so anywhere Gauteng ground is being worked, the record has it covered.
Made for the firms mines bring in. Drillers and shaft-sinkers, engineering practices, sample labs, processing-plant builders, capital-equipment dealers and freight movers all rely on AMIQ to secure their next piece of Gauteng work.
The whole province at a glance. All 26 Gauteng projects collect into one searchable place, set among 560-plus projects nationwide and more than 2,200 right across the continent.
Why Gauteng remains the birthplace of the industry
This province was not simply a place where mining occurred. Mining is the reason it exists at all. The 1886 strike on the Witwatersrand drew a camp that had become Johannesburg inside a single generation, and the richest, deepest reef of gold anyone had ever found turned a band of Highveld into the country's economic motor. The smallest of the provinces by surface area grew into the birthplace of an industry that still leaves its mark on South Africa.
The reef has not gone quiet. Mines today drive Witwatersrand gold extraction deeper into the earth than almost anywhere else on the planet, while a second industry alongside them recovers gold from the dumps a century of mining piled across the surface. Out east, where the province borders the Highveld coalfields, coal mines supply power and heavy industry, mixing the old gold ground with the bulk minerals the economy depends on, and the same reef carries westward into bordering North West.
Beyond Pretoria, Petra Diamonds keeps the Cullinan mine going on one of the most renowned kimberlite pipes anywhere, the origin of the largest gem diamond on record. That mix of deep gold, retreatment, coal and diamonds is precisely where the work lies. A subscription to AMIQ brings the per-project spend figures and the confirmed names tied to each site, the mining companies running them among them.
The districts driving Gauteng mining
Activity tracks the sweeping curve of the Witwatersrand reef and the country around it, running from Johannesburg out to the East and West Rand and on to the Cullinan pipe past Pretoria. Each district mines a separate slice of the deposit and holds a pipeline of live projects of its own.
Johannesburg / Witwatersrand
This is the central Rand, the spot where the reef was first cut and the city then rose directly above it. Deep gold workings and surface retreatment here keep calling on shaft, plant and processing contractors.
Explore →East Rand
Out past Johannesburg toward Springs and Brakpan lies the East Rand, holding deep gold reefs and a few of the biggest retreatment plants in South Africa, which keeps pumping and reclamation crews in constant demand.
Explore →Cullinan / Pretoria
Outside Pretoria sits the Cullinan mine, where Petra Diamonds works a celebrated kimberlite pipe. The block cave running below ground sustains a long line of engineering, processing and maintenance contracts.
Explore →West Rand
To the west of Johannesburg, the West Rand carries some of the deepest gold mines anywhere on earth, the Mponeng depth extension among them. Operations at that depth call for specialist shaft-sinking and rock-engineering firms.

Mining in Gauteng: the questions suppliers ask
How many active mining projects does Gauteng have?
Africa Mining IQ lists 26 live mining projects in Gauteng, drawn from a national total north of 560. They cover every phase, early-stage ventures through to producing mines and retreatment plants, and reach across gold, coal, diamonds and industrial minerals throughout the province.
What does Gauteng mine?
Gold leads, lifted from the deep Witwatersrand reef and won a second time from old retreatment dumps. It accounts for 14 of the live projects. Behind it sit coal at 7 along the eastern edge, three industrial mineral sites, the lone Cullinan diamond operation and a small fluorspar holding.
Does Gauteng still produce gold?
It does. Mines on the Witwatersrand basin such as the Mponeng depth extension, Blyvoor and Qala Shallows keep working the reef thousands of metres down. At the same time, Ergo and DRDGold recover gold from the retreatment dumps that a hundred years of mining left behind.
What makes the Cullinan mine notable?
Cullinan is Petra Diamonds' operation just outside Pretoria, set on one of the most renowned kimberlite pipes in the world. The largest gem-quality diamond ever recovered, the Cullinan Diamond, came from here, and its block cave below ground sustains a long run of engineering and processing contracts.
What is the Witwatersrand?
It is the gold-bearing reef that curves across Gauteng, stretching from the West Rand through Johannesburg and on to the East Rand. The 1886 strike happened along it, Johannesburg was built directly above it, and it stands as the richest gold deposit ever found.
How do suppliers get onto Gauteng projects early?
Getting in before requirements harden is the whole game. Africa Mining IQ flags which Gauteng sites are live and the phase each has reached, hands over the checked owner, engineer and EPC details, and fires an email or text whenever a Gauteng project joins the list or advances.
