AMG Lithium Processing Strategy Targets a Fully Western Supply Chain

AMG Critical Materials (lithium)

AMG lithium processing strategy is moving toward a more fully Western supply chain. The company is exploring new lithium processing investments in both Brazil and Portugal. Its goal is to reduce dependence on China in the spodumene midstream. As a result, AMG lithium processing strategy now centers on regional integration and logistics control.

This matters because AMG already operates one of the few Western lithium refining platforms. The company runs a lithium hydroxide refinery in Germany using spodumene from Brazil. However, the concentrate still needs processing in China before final refining in Europe. Therefore, AMG lithium processing strategy is aimed at removing one of the biggest inefficiencies in its current chain.

The commercial logic is straightforward. Processing closer to extraction sites would cut transport complexity and reduce costs. It would also improve supply visibility for European refining operations. Consequently, the company is trying to build a more resilient and politically aligned lithium system.

Lithium Processing in Brazil Could Deepen Upstream Integration

Lithium processing in Brazil could become the first major pillar of this strategy. AMG is already the second-largest spodumene producer in the country. That gives it a strong upstream position from which to expand into midstream conversion. Therefore, Brazil offers both feedstock security and industrial logic.

Brazil’s policy environment also supports that direction. Authorities have repeatedly encouraged more value-added critical minerals processing inside the country. That policy push aligns with AMG’s stated aim of building an integrated upstream chain in phases. As a result, lithium processing in Brazil could fit both national strategy and company economics.

The country also offers broader structural advantages. Brazil combines legal stability, resource strength, and growing industrial interest in critical minerals. Those conditions make it an attractive location for longer-term investment. Meanwhile, local processing would reduce the need for back-and-forth shipments through China.

Lithium Processing in Portugal Could Strengthen Europe’s Refining Base

Lithium processing in Portugal offers a different but equally strategic advantage. Portugal sits much closer to AMG’s German refinery, which could simplify logistics and shorten transport routes. That would help reduce cost and improve coordination across the European chain. Consequently, lithium processing in Portugal could become a natural extension of AMG’s existing refining base.

The Barroso project adds further importance to that option. AMG is the top shareholder in Savannah Resources, which is developing what is expected to be Europe’s largest lithium mine. Barroso is scheduled to come online in 2028. Therefore, Portugal could eventually provide both local mine supply and closer midstream support for Europe.

AMG has not yet decided the timing, sequencing, or capacity of any new plants. A midstream project could emerge first in Europe or in Brazil. That uncertainty keeps the strategy flexible, but it also shows the company is still in evaluation mode. Meanwhile, its German refinery is expected to complete ramp-up to 20,000 t/yr by the end of this year.

The Metalnomist Commentary

AMG is addressing one of the biggest weaknesses in the Western lithium chain: the missing midstream. Mining and refining alone do not create supply security if China still dominates the upgrade step. If AMG executes well in Brazil or Portugal, it could become one of the more credible builders of a truly Western lithium supply route.
