Vale Base Metals executive director Eduardo Bartolomeo has been named the company’s interim CEO, after chief executive Fabio Schvartsman and several other high-level executives resigned over the weekend. 

Schvartsman, along with company Ferrous and Coal directors Peter Poppinga and Lucio Flavio Gallon Cavalli, and Silmar Magalhães Silva, the head of Southeast Corridor operations, offered their temporary resignations during a Vale board meeting.

Federal and state prosecutors and police asked for the resignations in the wake of the Córrego de Feijão tailings dam collapse, which to date has killed more than 180, and left another 120 missing.

Vale’s head of its Pellets and Manganese group, Claudio de Oliviera Alves, will step into Poppinga’s role, and Mark Travers, the company’s head of legal, institutional relations and sustainability for Base Metals, will take over for Bartolomeo.
