Bahia Graphite Projects

  • Project Size: 6,344 ha over 8 Mineral Rights
  • Project Location: Araçuaí Orogen, in the central-eastern region of Brazil
  • Commodities: Graphite

PROJECT SUMMARY:

The Bahia Graphite portfolio is divided into two main projects, the Limeira and Jordania and two secondary projects, Cabeças, and Bonfim. The Limeira and Jordania projects are in the Araçuaí Orogen, along the southern margin of the São Francisco Craton. This area presents a complex tectonic history involving multiple subduction events with over 80 years of continued graphite production (6 active mines).

Libra’s tenements are located near established graphite producers such as Nacional de Grafite, Grafite do Brasil and South Star Battery Metals, within the highly active Eastern Brazilian Graphite Belt.

Libra benefits from exceptional proximity to key infrastructure, enabling future scalability and cost efficiency:

  • Railways connecting directly to major industrial hubs and export terminals
  • Atlantic ports like Salvador and Ilhéus, offering viable export routes
  • Hydropower plants, supporting a low-carbon development approach
  • Public airports facilitating efficient logistics and field operations

Libra’s assets are in mining-friendly jurisdictions with mature governance and are surrounded by both national and international players in graphite and lithium, reinforcing the region’s strategic importance.

Libra’s positioning combines strong geological potential with critical infrastructure access, aligning Libra with the growing global demand for sustainable, high-purity graphite.

Geology and Mineralization

The geological origin of these projects is sedimentary. During the Late Precambrian, pelitic sediments and carbon were deposited, which were subsequently transformed into high-grade metamorphic rocks and graphite during orogenic activity in the Early Cambrian.

The Barreira Formation (unconsolidated sandstone of Cretaceous age) covers most of the area, while the Jequitinhonha Formation is exposed in zones where the Barreira Formation has been eroded. Graphite has been identified in the Kinzigite gneiss. This unit is overlain by approximately 3 to 5 meters of Barreira Formation.

The mineralization is structurally controlled by regional faults and shear zones, concentrated in soft zones associated with folding. The overall mineral trend in both projects follow a SE–NW orientation.

Confirmed Mineralization

  • Jordania: Exploration at this project was primarily conducted in the northern sector, where the Barreira Formation and outcrops of Kinzigite (graphitic gneiss and granulite) were identified. Samples within the Jordania Mineral Rights returned up to 0.9% Graphitic C while samples collected on the adjacent property returned grades of up to 19.82% Graphitic C, confirming the continuity of the mineralization trending SE-NW.
  • Limeira: Saprolite and gneiss outcrops containing graphite flake of small, medium and jumbo sizes are observed on this project. Local grab samples returned up to 7.2% TGC.
