MSR mining reserves are located in the main salt lakes of the Andes region, in the provinces of Catamarca, Salta and Jujuy in Argentina. The salt lakes with significant concentrations of borates, such as tincalonite and ulexite, are legally owned properties of the MSR Group. The main reserve and exploitation source of the company is Salar del Hombre Muerto, Catamarca, located at an altitude of 4,100masl. It is being mined at a rate of 60,000 tons per year and it has more than 2,000,000 tons of proven reserves and potential reserves of around 6,000,000 tons.
All of MSR properties in the salt lakes also have reserves of lithium and potassium salts. For this reason, MSR created a new project for the development and exploitation of these minerals. Virgen del Valle Litio is a first-class sustainable project created by Minera Santa Rita S.R.L. with a strategic location. The project consists in the extraction, production and commercialization of refined lithium products.
One of the most important operating mines is “Patito” mine in Salar Centenario, Salta. It is famous for the workers’ devotion to Salta’s patron saints: el Señor y la Virgen del Milagro.
