Royal Gold Inc
↗RGLD
Royal Gold Inc enquires and manages precious metal royalties and streams with a focus on gold. The company purchases a percentage of the metal produced from a mineral property for an initial payment without assuming responsibility for mining operations. Similarly, precious metal streams are purchase agreements with mine operators providing the right to purchase all or a portion of one or more metals produced from a mine in exchange for an upfront deposit payment. Generally, Royal Gold does not work on the properties in which it holds royalty and streaming assets. The company owns a portfolio of producing, development, evaluation, and exploration royalties and streams, and the majority of group revenue is generated from Canada, Mexico, Chile, and the United States.
