Rich mine deposits are a type of mineral deposit that contains valuable metals or minerals in high concentrations. LODES are an example of rich mine deposits, which are veins of ore that are found in fissures or cracks in rocks. These deposits are usually formed by hydrothermal activity and can contain a variety of minerals, including gold, silver, copper, lead, and zinc. Rich mine deposits are highly sought after by miners and prospectors due to their potential for yielding large amounts of valuable minerals.
