6. Alluvial Gold: Alluvial gold is gold that has been eroded from its original source and transported by water, often ending up in riverbeds or sediment deposits. Alluvial gold can come in various forms, including nuggets, flakes, and dust. The value is determined by factors such as the size and purity of the gold particles.
7. Placer Deposits: Placer deposits are concentrations of gold that have accumulated in streambeds, riverbeds, or other sedimentary environments. Gold in placer deposits can be found as nuggets, flakes, or dust, and the size can vary widely depending on factors like water flow and local geology with their value, depending on the richness of the deposit and the ease of extraction.
8. Microscopic Gold: Sometimes, gold can be present in extremely small quantities and may not be visible to the naked eye. This “microscopic gold” can be dispersed within rock or sediment and might require advanced techniques like chemical extraction or microscopy to detect and recover.
It’s important to note that the value of gold is not solely determined by its shape and size. Factors like purity (measured in karats or fineness), current market prices, and the costs of extraction and refining also play a significant role in determining the overall value of the gold found by prospectors. Additionally, collector demand can impact the value of unique specimens and larger nuggets.
