The Santa Rosa mine is located in the gemstone rich area of Minas Gerais about 150km from Governador Valadares, and is the nucleus of Interprospekt’s Brazilian mining activities. In the 60’s and 70’s, hundreds of miners worked and lived at the historic mine, with the pro-duction eventually coming to a stop when the miners hit hard rock. In the following years, two partners took up mining again, working the hard rock with modern methods and equipment. During this time many world famous mineral specimens were discovered at the Santa Rosa mine. During the last 15 years mining activities focused mainly on the Mutuca pegmatite lo-cated on the same mining claim only about 1 kilometer away. Mutuca has produced fantastic tourmaline in vivid green and blue color hues. For the past 10 years Interprospekt has been actively involved in the excavation and build out of the operation.
