May 18, 2015· This precious metal has been found in streams, in the sides of rock outcroppings, and of course, under the earth. At different times in the earth's history, hot fluids circulated through gold-bearing rocks and because of the weight and chemical properties of the gold, the gold may have been carried off to form a vein or a lode.
We have over 50 different gold books and gold maps that show where gold has been found in the past and provide instruction on gold prospecting methods. Also available are gold pans in a variety of sizes and gold panning kits which include everything that you will need. Lode Gold. Lode gold occurs within the solid rock in which it was deposited.

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 ...

Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold. This is referred to as 'native gold'.
Gold is mostly liberated from rocks and the particles of gold gets concentrated at some places in rivers. These deposits are considered as placer deposits. Gold can be recovered from placer deposits with the panning process. This type of gold is spread widely across the rivers and therefore, found .
