History of mining in the Chapada Diamantina
1. Gold in the Chapada
In the 18th century, gold was found in Rio de Contas and Jacobina and became the main wealth of the region. During this period, the Estrada Real was built to facilitate the transport of gold, and later diamonds, linking the mining areas with the commercial centres and the coast.
Historical origins of the Royal Road
The Royal Road is one of Brazil’s most important historical routes, dating back to the 17th century.
Its construction was driven by the need to transport gold, and later other minerals such as diamonds, from the mining regions of the interior to the coast, where they were shipped to Europe.
Initially, the trails were rudimentary, created by prospectors and travellers.
As the demand for gold increased, the colonial authorities began to formalise and improve the road, encouraging the construction of more solid infrastructure, including bridges and rest areas.
The economic importance of the Royal Road
The Royal Road was vital in transporting gold and diamonds to ports for export. This had a significant impact on the colonial economy, making Brazil one of Europe’s main sources of precious metals.
The road also facilitated cultural and commercial exchange between regions, allowing merchants and travellers to establish trade links.
Along the Estrada Real, several towns grew and developed, such as Ouro Preto, Tiradentes and Lençóis, becoming commercial and cultural centres.
Today, the Estrada Real is an important tourist corridor, attracting visitors interested in the culture and history of the region and providing a new source of income for local communities.

2. The discovery of diamonds
At the beginning of the 19th century, the first diamond deposits were discovered in Mucugê.
In 1844, a prospector found diamonds in Mucugê, leading to an expedition that yielded six arrobas of “thick diamonds”.
3. Start of a new mining cycle
The discovery of diamonds led to a new cycle of exploration, with Mucugê, Andaraí, Palmeiras and Lençóis becoming wealthy towns. Lençóis became the third most important city in Bahia.
4. Gold and diamonds in the 19th century
For most of the 19th century, Bahia was the world’s largest producer of diamonds. However, the discovery of deposits in South Africa in 1867 caused the price of diamonds to fall, affecting Brazilian production.
5. The decline of mining
In the 1850s, Lençóis had a population of about 25,000, who lived from tourism.
Production of carbonado, a variety of diamond, continued, but mining began to decline in the early 20th century.
6. The era of the colonels and the economic crisis
Around 1870, diamond mining came to an end, marking the beginning of the Era of the Colonels.
The economic crisis of the mid-20th century was caused by the exhaustion of diamond mining.
Era of the Colonels
The Era of the Coronels refers to a period in Brazilian history that lasted roughly from the end of the 19th century to the beginning of the 20th century, especially in the 1920s and 1930s.
The term “colonels” refers to local leaders, usually landowners or political leaders, who exercised great influence and power in their regions, especially in the interior of Brazil.
7. Last gasps of garimpo
A significant last gasp of garimpo occurred in the 1980s with mechanised mining, but this practice was banned in 1996 due to environmental concerns. Mining ceased in 1994.
8. The age of the synthetic diamond
In the 20th century, the advent of synthetic diamonds led to the extinction of carbonado mining. However, gold and diamonds can still be found in the Chapada, albeit by artisanal methods, since Ibama banned the use of dredges for mining in 1998.
Gold is still found in Rio de Contas, while diamonds are more common near Mucugê and Igatu.
9. Development of artisanal mining
After the ban on mechanised mining, artisanal mining reemerged as a common practice in the region.
Miners began using traditional techniques, such as beaters and hoes, to adapt to the new regulations.
This form of garimpo is more sustainable and less damaging to the environment, allowing many locals to continue to make a living from artisanal diamond and gold mining, especially in areas such as Rio de Contas and Mucugê.
Despite the difficulties, many garimpeiros continue to work in difficult conditions, but with a deep respect for nature.
10. Tourism wealth
Since the 1990s, tourism has become the main source of income in Chapada Diamantina, with the creation of the Chapada Diamantina National Park and the listing of Lençóis as a National Heritage Site in 1973.
11. The reality of Garimpo today
Recently, some artisanal mining has continued, but exploitation is limited. Many locals believe that only 12% of the diamonds in the Chapada Diamantina have been explored.
