Foundation and beginnings of activity

Minera Santa Rita was founded in 1970. Our activity started in the town of Sierras Bayas, Province of Buenos Aires, Argentina, with a small hydrated lime plant meant to supply the construction industry. The factory was in operation for 17 years, until the company took a significant turn.


Mining Promotion Law

The company took a significant turn encouraged by the new Mining Promotion Law enacted in Argentina in the 1990s, when it began to work with heavy machinery and mining equipment for exploration and exploitation.

The vision of our founder, Mr. Nassib Haddad, placed the company in a competitively advantageous position to provide mining services to the most important projects in Argentina.

MSR was a leader in reverse air drilling during a period of high demand for exploration and mining in Argentina during this time.


Production plant

In 1998, Minera Santa Rita acquired a production plant for Bórico Acid in the town of Campo Quijano, Salta, Argentina and began a continuous process of growth in terms of mining, production and sales. Currently, MSR is one of the world leaders in the production of Boron derivatives.

Mission and Quality
