Confidence Reef is a historical gold-bearing quartz vein situated within the Kloofendal Nature Reserve, in close proximity to Roodepoort, South Africa.

The techniques and infrastructure introduced during this early phase, such as stamp mills for ore processing, formed the foundation for modern mining practices and facilitated Johannesburg's rise as a major global player in the gold industry.

[3][4] The Struben brothers were engaged in active mining operations at Confidence Reef until 1888, extracting gold from a quartz vein that they had discovered.

With the passage of time, the importance of the Confidence Reef grew, not only in terms of its role in mining activities but also in relation to its status as a site of South African heritage.

The Confidence Reef is located within the Walter Sisulu National Botanical Garden in Roodepoort, South Africa, making it accessible for educational visits and a reminder of the country's rich mining heritage.

This monument, located at the Confidence Reef site, honors their role in the birth of Johannesburg and South Africa's gold industry.
