Meridian secures trial production license for Rio Madeira manganese prospects

Meridian Mining S.E. said Sept. 10 that it secured a Guia de Utilização permit, or a trial production license, from the National Department of Mineral Production for the extraction of 6,000 tonnes of manganese oxide concentrate per annum from the exploration license that covers the Califórnia, Eduardo Mendes, and Calça Frouxa prospects, all part of the Rio Madeira property in Brazil.

These prospects have been partially mined for colluvial material, with the remaining colluvial and vein material now able to be extracted through the granted license.
