How to Identify a Gold Bearing Area | Sciencing

Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and funds. In other words, those who study geological surveys, land formations, rock structures and gold prospecting history prior to prospecting may have a better chance of finding desired amounts of gold.

Placer deposit | geology | Britannica

Stream placers, by far the most important, have yielded the most placer gold, cassiterite, platinum, and gemstones. Primitive mining probably began with such deposits, and their ease of mining and sometime great richness have made them the cause of some of the world's greatest gold and diamond "rushes." Stream placers depend on swiftly flowing water for their concentration. Because the
