About Us

Minera San Cristobal (MSC) is a world-class Bolivian mining company, and one of the South American country’s largest and most innovative employers.

MSC focuses on mining for silver, lead and zinc in the remote province of Nor Lipez in the Bolivian department of Potosi.  MSC is a wholly owned subsidiary of the Sumitomo Corporation, one of Japan’s leading industrial groups with more than 400 years of operating experience.

The San Cristobal mine is located approximately 500 kilometers (≈310 miles) south of the city of La Paz, and 90 kilometers (≈55 miles) southwest of the town of Uyuni.  The average elevation of the area is approximately 3,900 meters (≈12,800 feet, or 2.4 miles) above sea level. As the nation’s largest mining company, the work can only be accomplished through an ongoing commitment to safety, professionalism, teamwork and transparency.

MSC is dedicated to continuous improvement, engagement and dialogue with all the key stakeholders, and is committed to Bolivia and to assuring that the San Cristobal mine benefits the Bolivian state and people as broadly as possible.

MSC is proud to be recognized for having achieved the requirements for ISO 9001 certification, the international process establishing the standards for quality management systems.

MSC also complies with all Bolivian environmental regulations, as well as those set forth by the ISO 14001 environmental management standards and OHSAS 18001 parameters for health and safety.*  MSC also works diligently to meet all local labor legislation guidelines and the highest global standards for the health and safety of all its employees.
