For centuries, various regions in Argentina utilized a technique known as panning to extract gold from rivers, a practice that had largely fallen out of use. However, recent revelations show that it is still possible to obtain nuggets of this precious metal in certain Argentine rivers. One particular river has caught the attention of experts due to the presence of gold particles in its tributaries, prompting interest in the revival of this traditional method of gold extraction through filtration techniques.

Located in San Luis is a village called La Carolina, situated at the base of the Tomolasta hill. This area is recognized as one of the world's best tourist destinations according to the World Tourism Organization. La Carolina, founded in the 18th century, is characterized by its mountains, picturesque landscapes, and a preserved mining tradition. The village offers experiences in gold panning at its "yellow river," appealing to tourists who want to participate in this historic practice and enjoy the natural beauty of the region.

The method of extracting precious metals from water involves careful technique in filtering and separating gold from water using traditional means. This rediscovery not only enriches the historical tapestry of Argentina's mining heritage but also poses a potential boost to local tourism by attracting visitors eager to engage with its gold mining history, thereby supporting the economy of La Carolina and similar areas.
