Last week, Reuters reported that divorce proceedings between current Sigma Chief Executive Ana Cabral-Gardner and Calvyn Gardner, her husband and former co-CEO, had triggered several lawsuits, including a dispute over some of the mineral rights where Sigma plans to build mining pits. At the time, Sigma told Reuters the dispute would not affect its expansion plans, as it said it can develop the area via a "waste sharing agreement." Gardner left his co-CEO role in January, and Sigma announced a new chief financial officer in August.
