Sal de Oro II — lithium carbonate (POSCO)
Second stage of POSCO’s Sal de Oro lithium complex in the Salar del Hombre Muerto, on the disputed Salta/Catamarca border strip: it adds a 23,000 t/year lithium carbonate plant to the hydroxide plant opened in Oct-2024 in General Güemes (Salta). Approved by RESOL-2026-1157-APN-MEC with USD 207,936,427.20 in computable assets and a RIGI accession date of 12-Jun-2026. A first-order data point for the satellite-services thesis: the committed supplier development plan is 21.02% of the amount allocated to suppliers, goods and works, and the resolution validates it against the 20% floor of section 47(l) of the annex to decreto 749/2024 — the national RIGI regime — not against the 70% of Salta’s Ley 8164 It is concrete evidence that a RIGI project vehicle is measured by the national 20% yardstick, which is less than a third of the provincial one.

- The works, milestone by milestone — We have not built this project’s timeline. Dated milestones with their source close it.
- Who already has a contract — We have not surveyed this project’s awards. A published contract with its source closes them.
How to supply itwhere to register, what they ask for and what they will buy
What it will need and has no supplier for yet
Construction and assembly of a lithium carbonate plant in the salt flat
mediumAdding a carbonate line (~23,000 t/year) to the existing operation concentrates civil-works and high-altitude electromechanical assembly capex.
Logistics and chemical inputs (soda ash, lime) for the NOA lithium corridor
mediumCarbonate chemistry demands reagents and outbound logistics towards ports; it adds to the demand of the Hombre Muerto corridor.
- How to become a supplier — We have not built this project’s entry map. It is our gap, not a prohibition: it closes by opening the provincial register and the operator’s single window.
- What it will buy, and when — We have not built this project’s phase → demand chain: its schedule still has to be crossed with the province’s catalogue of markets and trades.

What it leaves in Saltajobs, works, taxes, promises and the outlook
- The works that stay behind — We have not surveyed this project’s permanent works. A published size with its source closes them.
- What it already pays in taxes and royalties — We have not broken down this project’s local fiscal contribution: the primary source that sets each item still has to be opened, and an act of the State is not published on press backing.
- Who promised what — We have not surveyed the public promises about this project. A dated, verifiable commitment with its source closes them.
What could stall itrisks and how to track them
- What could stall it — We have not documented this project’s risks. An identifiable vector with its source closes them.
- How to tell whether it is advancing — We have not defined this project’s indicators: what observable fact marks its progress still has to be identified.
