Gold prospecting is the act of searching for new gold deposits. Methods used vary with the type of deposit sought and the resources of the prospector. Although traditionally a commercial activity, in some developed countries placer gold prospecting has also become a popular outdoor recreation.
Gold prospecting is the act of going equipped to find gold in rocks or in stream beds with a view to exploiting that discovery. This usually means individual prospectors, as opposed to those trained and educated individuals working for mining companies.
