Lithium Milestones and Phases

Phases I & II Lithium Concentrate

Monetization of substantial lithium mineral deposits currently residing in AMG Mineração’s tailings ponds and tailing stockpiles; AMG will construct two lithium concentrate (spodumene) production facilities, co-located with AMG Mineração’s tantalum mine and upgrading plant in Brazil

Initial production of 90,000 MT of lithium concentrate per annum, with a target to expand to 180,000 MT by end of 2019


Lithium concentrate (spodumene) plant studies completed by Outotec (Q4 2015)

  • Conceptual study
  • Pre-feasibility study

The pilot plant received basic maintenance and wet magnetic separators were rented, placing the pilot plant back into operational condition.
