Description Solitude can be a precious resource, but Solitario Exploration & Royalty is more interested in finding precious minerals. The company explores and develops gold, silver, platinum, and zinc properties in Brazil, Mexico, and Peru. Solitario has formed alliances to help finance its exploration work with industry giants like Newmont Mining and Anglo Platinum. None of its properties are in development. The company changed its name from Solitario Resources in 2008. The following year it agreed to buy Metallic Ventures Gold, which has properties in Nevada. Not long after, International Minerals came in with its own offer for Metallic Ventures.
