• Researcher Carina Schoonraad has discovered that the mine dumps around Johannesburg, South Africa, contain billions of dollars' worth of invisible gold. Her research has revealed that these mine dumps, which were previously considered waste, actually contain significant amounts of gold that can be extracted and processed. This finding has the potential to transform the mining industry in the region and provide economic opportunities for local communities.

• Schoonraad's research involved using advanced analytical techniques to identify the presence of gold in the mine dumps. She found that the dumps contain a substantial amount of gold that was not recovered during the initial mining process. This "invisible gold" is present in the form of microscopic particles that are embedded in the rock and soil. Schoonraad's work has demonstrated the potential for these mine dumps to be a valuable resource that can be tapped into.

• The discovery of this invisible gold has generated significant interest from the mining industry and government authorities. Schoonraad's findings have the potential to create new economic opportunities and jobs in the region, as well as to reduce the environmental impact of mining by repurposing the existing mine dumps. However, the process of extracting and processing this invisible gold will require significant investment and technological advancements, and there are still challenges to overcome in terms of the economic and environmental feasibility of this endeavor.
