Gem Prospecting & Hunting: Find Precious Stones in Riverbeds

While rivers are excellent locations for prospecting, dense minerals like gemstones are rarely scattered uniformly. They concentrate in specific, smaller volumes of alluvial gravel, often referred to as "pay-dirt." In this lecture, you will learn how to identify these high-potential zones, how to sample them effectively, and how to begin the crucial process of sorting your finds to uncover the best specimens.

To become a successful alluvial gemstone prospector, you must be prepared to tackle various field challenges. In this lecture, we will work through 7 practical, hands-on exercises together. By solving these real-world scenarios, you will develop the critical problem-solving skills needed to confidently face any future prospecting challenges you encounter in the field.

High-quality gemstones are often dispersed within river gravel, requiring careful extraction. In this lecture, I will demonstrate how to dig and excavate alluvial sediments efficiently, helping you save energy while maximizing your results.
