Salta, Argentina

Life-of-Mine of 40 years4

Resources estimated at c. 10 Mt LCE

(providing further upside potential)

Eramine Sudamerica (50.1% Eramet) owns 100% of the entire salar with perpetual

mining rights

Construction in partnership with Tsingshan

1. Electric cars = Battery Electric Vehicles + Plug-in Hybrid Electric Vehicles + Hybrid Electric Vehicles
2. Battery-gradeLithium demand for all applications
3. LCE (Lithium Carbonate Equivalent)
4. Based on proven and probable reserves at the Ratones deposit (1.1Mt LCE),

and on a project designed for 24ktpa LCE

Developed in-house, Eramet's Direct Lithium Extraction technology combines strong competitiveness…

Direct Lithium Extraction (DLE)

Proven industrial process over the past 20-years(aluminum-based lithium sorbent)

Proprietary lithium sorbent working

at native temperature of the brine

(20°C)

90%1 lithium recovery yield of the

DLE unit

> Industry leading yield much

higher than traditional evaporation process (c. 40-50%)

> Almost twice less brine pumped2

> Thus, optimized management of the deposit's hydric balance

4 BofA Lithium (DLE) / Battery Materials (virtual) Fieldtrip

1. 87% process yield overall
2. Vs conventional process, based on the same brine characteristics (notably Li concentration)

… as well as high sustainability standards

Water recycling

Regeneration of the lithium sorbent only by water (DLE based on titanium or manganese sorbents use acid) and at 20°C

Water recycling by reverse osmosis & forced evaporation

60% process water recycling rate

Efficient purification

High selectivity of the DLE unit

Nanofiltration and ion exchange for solid waste minimization

Swift production

1 week lead time vs. 12-18 months on evaporation process
