The Saramacca gold deposit is located in the Republic of Suriname, South America, 100 kilometres southwest of the capital city of Paramaribo and 25 kilometres southwest of IAMGOLD’s Rosebel Gold Mine. The deposit occurs within the Marowijne Greenstone Belt of the Paleoproterozoic Guiana Shield, largely constrained between 2.26-2.08Ga. The Guiana Shield is regionally extensive, extending from the Amazon River in Brazil to the Orinoco River in Venezuela, covering an area of more than 900,000 km2. Fundamental to exploration, the Guiana Shield has undergone prolonged chemical weathering, reflecting a humid, tropical paleo-climate that may have started as far back as the Cretaceous period. The chemical weathering has produced a well-preserved, laterite/saprolite profile, which locally extends up to 100 metres in depth from surface.

The Marowijne Greenstone Belt is divided into the Paramaka and Armina Formations, dominated by volcanic basalts and a mixed metasedimentary, greywacke–mudstone sequence, respectively. These are in turn overlain unconformably by the Rosebel Formation, comprisingquartz-rich arenites interlayered with polymictic conglomerates. The Saramacca gold deposit is hosted by metabasalts of the Paramaka Formation. Younging from southwest to northeast, the main units of the Paramaka Formation are a lower massive basalt successively overlain by a thin, amygdular basalt unit and a thick unit of pillowed basalt.
