The term 'Rich Deposit' refers to a large concentration of valuable minerals, such as ORE or LODE, that can be mined for profit. A LODE is an ORE deposit that is found in fissures or veins in rock, while ORE is a naturally occurring mineral from which a metal or valuable mineral can be extracted. These deposits are often found in areas with a long history of mining, and can be a great source of wealth for those who are able to access them.
