Teacher notes

Purpose. A learner-centred investigation for a mixed-ability Grade 10 class (1–2 double periods, or set as homework with the Bedrock level done in class). Learners build an evidence-based argument rather than memorise a narrative. Toggle these notes off before projecting to a class.

CAPS alignment. History FET, Grade 10 Topic 6: mining capitalism; development of mining on the Witwatersrand; foreign capital; technology; emergence of classes; migrant labour; racial division of the workforce; African responses; link to the South African War. Skills: source analysis (usefulness, perspective, limitations), cause and consequence, constructing an argument.

Level 1 · The hook

Imagine South Africa in 1866

There is no Johannesburg. No mining giants. No trains hurrying investors to the Witwatersrand. Most people live on the land, and the interior is seen by Europeans as poor farming country.

1867

A boy on a farm near Hopetown picks up a shiny pebble by the Orange River. It turns out to be a 21-carat diamond.

1886

On a farm called Langlaagte on the Witwatersrand ridge, a prospector strikes the edge of the largest goldfield ever found.

Within thirty years, everything changed — where people lived, how they worked, who had money, and who had power.

But did everyone benefit from the wealth these discoveries created? That is what you are going to investigate.

Level 2 · Your challenge

Did the Mineral Revolution make South Africa richer — or more divided?

Before you see any evidence, take a first guess. There is no wrong answer yet — historians disagree about this too. You will vote again at bedrock, and compare.

In one sentence, why do you think so?

The rule of this investigation

Don't choose an answer yet. Investigate the evidence first. A historian's opinion is only as good as the evidence behind it.

Teacher notes

Capture a quick show of hands here and record the class split. Returning to it at Level 14 makes the "did the evidence change your mind?" reflection concrete. The essential question deliberately has no single correct answer; the mark is for the quality of evidence and reasoning.

Level 3 · The map

The Mineral Revolution in one visual

The discovery of diamonds at Kimberley (1867–1871) and gold on the Witwatersrand (1886) set off a chain of changes. Tap each link to read what it means. This is your map for the whole investigation.

Diamonds are found near the Orange River and then at Kimberley. Thousands of diggers rush in. Kimberley becomes the first big industrial town in the interior.
Gold is found on the Witwatersrand. Unlike diamonds, the gold is low-grade and deep underground — getting it out is a massive engineering job.
Small diggers cannot afford deep mining. Big companies with heavy machinery take over. This is the birth of mining capitalism.
Money flows in from London and Europe to pay for shafts, pumps, stamp mills and railways. Investors expect profits in return.
Mines need enormous numbers of workers. A system of migrant labour develops: Black men travel from rural areas to work on contracts and live in compounds.
A tent camp in 1886 becomes a city of about 100 000 people by 1896. Railways, banks, shops, factories and stock exchanges follow.
Skilled white workers earn high wages; Black workers earn a fraction, live in closed compounds and must carry passes. Wealth and hardship are shared very unequally.
Britain's interest in controlling the gold leads to the Jameson Raid (1895–96), the South African War (1899–1902) and, eventually, the Union of South Africa (1910).

Think about it

Which link in this chain do you think affected ordinary people the most? Keep it in mind — you will come back to it.

Level 4 · Diamonds

The diamond rush

Diamonds were discovered near the Orange River in 1867. Within a few years the dry farm at Colesberg Kopje had become Kimberley — a chaotic town of tents, taverns and thousands of people digging for a fortune.

1867The "Eureka" diamond is found near Hopetown. Prospectors begin arriving along the Orange and Vaal rivers.
1871Diamonds are found on Colesberg Kopje. The "New Rush" becomes Kimberley. Thousands of small claims are pegged — many worked by Black diggers as well as white diggers at first.
1870sClaims are dug deeper and deeper. Walls collapse, water floods the workings, and hauling gravel to the surface becomes expensive. Individual diggers cannot cope.
1880sRicher men buy up claims and combine them. Mining becomes capital-intensive: steam engines, pumps and hauling gear replace buckets and ropes.
1885Kimberley mines introduce closed compounds: Black workers live locked inside fenced barracks for the length of their contracts, supposedly to stop diamond theft.
1888Cecil Rhodes and Barney Barnato merge their companies into De Beers Consolidated Mines, which controls almost all of the world's diamond production.

Did you know?

Kimberley's Big Hole was dug largely by hand — pick, shovel and bucket. It reached about 240 metres deep before open-pit mining stopped in 1914. It is still one of the largest hand-dug excavations in the world.

Think about it

What happens when something valuable is discovered, but getting it out becomes too expensive and complicated for individuals?

The people with money win. Those who can raise capital buy out those who can't, and ownership concentrates in a few hands. That is exactly what happened at Kimberley — and it set the pattern for the goldfields.

Teacher notes

Differentiation: weaker learners can answer the think-question with one sentence; stronger learners should use the word "amalgamation" and explain why deeper digging favours large companies. Kimberley's early phase is a good moment to challenge the assumption that Black South Africans were only ever labourers — some held claims before 1870s restrictions pushed them out.

Level 5 · Source Lab A

Source A: Kimberley, 1896

Historians don't just read about the past — they interrogate evidence. Here is a real photograph. Be a source detective.

Black-and-white photograph of the Kimberley diamond mine in 1896: a vast open pit criss-crossed by hundreds of hauling ropes, with small figures of workers on the rock terraces. — Source A · *Diamond mine with workers at Kimberley, South Africa, 1896* [photograph]. Photographer unknown. Wikimedia Commons, public domain. View original ↗

Who: Unknown photographer
When: 1896 — eight years after De Beers took control of Kimberley
Type: Primary source: a photograph taken during the period

Look

What can you actually see? (Ropes, terraces, people, machines…)

Think

What can you infer about the work and the scale of mining?

Question

What would you want to ask the photographer?

Historical thinking

Whose experience does this source show — and whose is missing? How useful is this source for understanding diamond mining? (1 = barely, 5 = very)

Justify your rating. What does the photograph NOT tell us?

Useful for: scale, technology (hundreds of hauling ropes = mechanised hoisting), the physical danger of terraced digging. Silent on: wages, race, compound life, who owned the claims, workers' own views. A photograph shows what the photographer chose to frame — the workers here are tiny, almost invisible. That is itself a clue about whose story the image was made to tell.

Teacher notes

Model the LOOK → THINK → QUESTION routine aloud once before learners try it. The usefulness scale is designed so that any rating is defensible if justified; reward "it is useful for X but not for Y" answers, which is the CAPS Level 3–4 source skill.

Level 6 · Gold

Gold changes everything

In 1886 gold was discovered on the Witwatersrand, in the Boer republic of the Transvaal (ZAR). It was the richest goldfield in the world — but it was also one of the hardest to mine.

1886Gold-bearing reef is confirmed at Langlaagte. Within months, a mining camp is proclaimed. It becomes Johannesburg.
1887–1889Surface gold runs out quickly. The reef dips steeply underground. Shafts, pumps and stamp mills are needed — and money to pay for them. The Chamber of Mines is formed (1889) so that mine owners can act together, especially over wages.
1890The MacArthur–Forrest cyanide process makes it possible to extract gold from the deep, sulphur-rich ore. Deep-level mining becomes profitable.
1890sMining houses backed by European capital — Wernher, Beit & Co.; Rhodes's Gold Fields; Barnato's JCI — dominate the Rand. Their owners become known as the Randlords.
1898The Transvaal produces roughly a quarter of the world's gold. Nothing else in Africa comes close in value.

Why gold was different from diamonds

Diamonds could be sorted from gravel by hand. Rand gold was a few grams in every tonne of hard rock, sometimes hundreds of metres down. That means: huge capital, heavy technology, and thousands of cheap workers. Gold was big business from the start.

CapitalTechnologyLabourInfrastructureCompanies

Think about it

Why could a single prospector with a pan and a pick never make it as a Rand gold miner?

Level 7 · Johannesburg

From goldfield to city

In 1886 Johannesburg was a camp of tents and wagons. The 1896 census counted about 100 000 people — more than half of them Black, and most of the white population foreign-born "Uitlanders" who had rushed in from Britain, Europe and Australia.

Think

If thousands of people suddenly arrive in one place looking for work and wealth, what changes? Choose the three you think matter most, then explain one.

Explain one of your choices. What actually happened in Johannesburg?

Housing: mining companies housed Black workers in compounds; white workers in boarding houses and suburbs; freed slaves' descendants, Indians and Chinese were pushed into segregated "locations". Transport: the railway from the Cape reached Johannesburg in 1892 and from Delagoa Bay (Maputo) in 1895. Businesses: banks, a stock exchange (1887), breweries, brickworks. Conflict: tension between Uitlanders and Kruger's government over votes, taxes and the dynamite monopoly — which Britain used as a reason to intervene.

Level 8 · Mining capitalism

Follow the money

Mining on the Witwatersrand needed enormous amounts of money. Follow where it came from — and where it went.

Investors mostly in London, Paris and Berlin, buying mining shares

Mining companies the "mining houses" of the Randlords

Technology + infrastructure shafts, stamp mills, cyanide plants, railways, electricity

Labour skilled white miners on high wages; tens of thousands of Black migrant workers on low wages

Gold production a quarter of the world's supply by 1898

Profits paid out as dividends — mostly to shareholders overseas

Mining capitalism

A system in which large companies, financed by investors' capital, own the mines and the machinery, and employ wage workers to produce minerals for profit. Power sits with those who own the capital, not with those who do the digging.

Think critically

Who had the money to control the mining industry?

Who provided the labour?

Were these two groups in the same position of power? Why or why not?

Teacher notes

The third question is the pivot of the whole resource: it links "richer" (profits, growth) with "divided" (who kept the profits). Use it for a paired discussion before writing. Stretch: ask where the dividends went — this opens the "South Africa joined the global economy" idea at Level 11.

Level 9 · Migrant labour

Follow the labour

Gold needs workers — and the mines wanted them cheap. The answer was a system called migrant labour (Afrikaans: trekarbeid).

Rural homefamily, land, cattle

Recruitmentcontract for 6–12 months

Mine + compoundunderground work; live in barracks

Return homewages spent on tax, cattle, goods — then leave again

Mines expand and need tens of thousands of workers

Pressure on rural communities hut taxes and labour taxes must be paid in cash; land is lost to white settlement; rinderpest kills cattle (1896–97)

Men leave to earn wages while women, children and elders keep the homestead going

Compounds and passes workers live in closed compounds; from 1895 must carry a pass in the Transvaal

A racially divided workforce skilled, well-paid jobs reserved for white miners; unskilled, low-paid work for Black migrants

The wage gap

By the late 1890s a white miner on the Rand could earn around eight to ten times what a Black underground worker earned. The Chamber of Mines worked to keep Black wages down — and cut them in 1897. Workers responded by deserting contracts, staying away, and choosing better-paying mines when they could.

Think about it

Why might someone choose — or feel compelled — to leave home and work far away? Notice the difference between "choose" and "feel compelled".

Teacher notes

"African responses to labour demands" is a CAPS requirement that textbooks often skip. Desertion, choosing mines, negotiating through chiefs, and later organised strikes (1913, 1920) all show agency. The choose/compel wording deliberately resists a "victims only" narrative. Source: Vosloo (2020) on the compound-to-hostel trajectory; SAHO on the migrant system.

Level 10 · Perspectives

One revolution, different experiences

Same Mineral Revolution — but it did not feel the same to everyone. Sort each consequence onto the person it mainly affected. Drag a card onto a profile, or tap the card and then tap a profile.

Mining investor

Owns shares in a mining house. Lives in Johannesburg — or London.

Black mine worker

On a 9-month contract, 400 km from home.

Urban business owner

Runs a shop, bar or brickworks in the boomtown.

Rural family

On a homestead in the eastern Cape or Basutoland. The men are away.

Now decide

Which of these four people would say "richer"? Which would say "divided"? Could the same person say both?

Teacher notes

Some cards have a defensible second home (e.g. "rising prices" hurts workers too). The checker accepts the primary match; use disagreements as discussion, not error. Extension: have learners write a 60-word diary entry as one profile.

Level 11 · Source Lab B

Source B: Inside the Kimberley mine

A second photograph, from the collection of the Rijksmuseum in Amsterdam. Compare it with Source A.

Sepia photograph mounted in an album: a view across the Kimberley diamond mine, with dozens of hauling wires stretching diagonally from the rim down into the terraced pit. — Source B · *Gezicht op de diamantmijn bij Kimberley in Zuid-Afrika* [View of the diamond mine at Kimberley in South Africa], late 19th century [photograph]. Rijksmuseum, Amsterdam (RP-F-2001-7-497-5), via Wikimedia Commons. Public domain / CC0. View original ↗

What do you see, and what can you infer?
This photograph was kept in a Dutch album. Why might a European collector have wanted a picture of a South African mine?
Whose perspective is represented? What information is missing?
Compare A and B. Which is more useful for answering our essential question — or are both limited in the same way?

Historian's tip

Both photographs were made by and for people outside the workforce. To hear the workers' side, historians turn to other evidence: songs, court records, missionary reports, letters and later oral histories. What a source cannot show is as important as what it can.

Level 12 · The bigger picture

Money, power and politics

The Mineral Revolution did not only transform South Africa from the inside. It plugged the region into the global economy — and made it a prize worth fighting for.

South Africagold, diamonds, cheap labour

⇄

Britaininvestors, machinery, banks, empire

⇄

Global capitalLondon stock market; the gold standard

Britain's industrial economy ran on raw materials, markets and investment. Gold mattered even more: the world's money system was based on gold, and London was its banking centre. Whoever controlled the Rand controlled a large share of the world's new gold.

Minerals

Money

Power

Politics

1895–96The Jameson Raid: a failed plot backed by Rhodes to overthrow Kruger's Transvaal government.
1899–1902The South African War between Britain and the Boer republics. Control of the goldfields was a central cause.
1910The Union of South Africa is formed — a single state, built around the mining economy, with political power reserved for white citizens.

Common misconception

"The Mineral Revolution caused apartheid."

Not quite — and the difference matters. Apartheid was a formal policy introduced after 1948, sixty years later. But the mines pioneered many of its tools: closed compounds, pass laws, a colour bar in skilled jobs, and a migrant labour system that kept Black families in rural "reserves" while men worked in towns.

A better sentence: The Mineral Revolution did not cause apartheid, but it laid economic foundations — cheap migrant labour, racial job reservation and pass controls — that later governments built segregation and then apartheid upon.

Think

Why would investors in London care about who governed the Transvaal?

Teacher notes

Keep the war to context only — CAPS covers it in the rest of Topic 6. The misconception box addresses the "everything before 1948 was apartheid" tendency; the distinction between segregation (pre-1948) and apartheid is examinable.

Level 13 · Cause and consequence

Put the story together

These ten developments are shuffled. Arrange them into a chain of cause and consequence. Drag to reorder, or use the arrows. There is more than one defensible order — the checker looks at the key links.

Choose ONE link in your chain and explain why the first development led to the second.

Level 14 · Can you dig deep?

Quick check

Five quick questions, then two you write yourself. Instant feedback — this is practice, not a test.

Your score

— / 5

6. Explain migrant labour in your own words (2–3 sentences).

Migrant labour was a system in which Black men left their rural homes to work on the mines for fixed contracts, living in compounds, and then returned home. Families stayed in the countryside. Mine owners liked it because it kept wages low; rural communities lost labour and were separated for long periods.

7. Give ONE way the Mineral Revolution benefited South Africa and ONE negative consequence.

Benefit: rapid economic growth — railways, cities, industries and a modern economy built around mining. Cost: a racially divided labour system (low wages, compounds, passes, colour bar) that concentrated wealth in few hands and laid foundations for later segregation.

Bedrock · The final challenge

Make your case

You have examined the evidence. Now answer the question — and prove it.

Essential question

Did the Mineral Revolution make South Africa richer — or more divided?

Evidence bank

Tap a piece of evidence to add it to your argument. Colour shows which side it tends to support: richer divided both. Strong arguments use a counter-argument too.

Build your argument

Use the scaffold. Each box becomes one part of your paragraph.

My claim — I argue that the Mineral Revolution… Evidence — One piece of evidence is… Explanation — This shows that… Counter-argument — However, another perspective is… Conclusion — Therefore, I believe…

Your paragraph

Teacher notes · assessing the argument

Suggested rubric (10): claim answers the question (2); evidence is specific and accurate (3); explanation links evidence to claim (2); counter-argument considered (2); conclusion follows (1). "Both" is not a cop-out if the learner explains for whom it was richer and for whom divided.

Level 16 · Resurface

Dig deeper

Did your opinion change after investigating the evidence? Why or why not? What is one thing you understand about the Mineral Revolution now that you did not understand before? Which source did you find most useful — and what was its biggest limitation?

History isn't remembering what happened. It's interpreting the evidence.
