Newmont’s Merian operation in Suriname is an open pit gold mine approximately 66 km south of the town of Moengo and 30 km north of the Nassau Mountains near the French Guiana. Newmont owns a 75 percent interest in the limited partnership, and Staatsolie Maatschappij Suriname N.V., Suriname’s state-owned oil company, owns the remaining 25 percent interest.
