Iamgold Sao Sebastiao gold deposit Staff reporter
The update puts the São Sebastião deposit at an indicated 3.3 million tonnes grading 4.39g/t gold for 0.47 million ounces and an inferred 3.56Mt at 3.78g/t for 0.43Moz, with a cut-off grade of 2.5g/t.

Iamgold had identified and acquired the greenfields project, 110km northwest of Belo Horizonte in Minas Gerais state, in 2007 and discovered São Sebastião with first pass drilling in 2011-2012.
The company has said several active mines in Brazil’s iron quadrangle exploited gold deposits of a comparable age, host rock type and mineralisation, such as AngloGold Ashanti’s Cuiabá and Lamego deposits.
Iamgold senior vice president exploration Craig MacDougall described São Sebastião as "an outstanding grass roots discovery made by our Brazilian exploration team who have continued to advance and improve the definition of resources since its discovery".
He said ongoing exploration would continue to target potential extensions and new discoveries.
He also acknowledged the exploration team’s safety record, saying they had recently surpassed 10 years without a recordable DART (days away, restricted, transferred) incident.
Iamgold has operations in Suriname, Burkina Faso, Canada and Mali, majority stakes in the Boto and Côté development projects in Senegal and Canada respectively, and other exploration projects in Mali, Canada and Nicaragua.
CEO Stephen Letwin is retiring within weeks after 10 years with Iamgold and COO Gordon Stothart will take the helm on March 1.
