Jujuy, Salta and Catamarca: Three Provincial Frameworks for the Same Lithium
Provincial ownership of mineral resources means the same mineral is governed by different rules depending on where it is extracted. We compare regimes, royalties and state strategies across Argentina's three producing provinces.
Mining federalism as a starting point
Argentina's 1994 Constitution established that natural resources belong to the provinces where they are located. For lithium, this means the country has no single regime: the same lithium carbonate extracted from Puna brines is governed by different rules depending on whether it is produced in Jujuy, Salta or Catamarca—the three jurisdictions that concentrate activity and made the country the world's fifth-largest producer.
This regulatory mosaic coexists with a common national framework—the Mining Code, the Mining Investment Law and, since 2024, the Large Investment Incentive Regime (RIGI). The overlapping of levels forces investors to read federal and provincial rules simultaneously before deciding where to base a project.
Jujuy: strategic resource and an active state company
Jujuy was a pioneer when it declared lithium a strategic resource by decree in 2011, a step that allowed it to intervene directly in the value chain. Its state company, Jujuy Energía y Minería Sociedad del Estado (JEMSE), routinely takes minority stakes—around 8.5%—in projects operating in its territory, adding an equity presence on top of royalty collection.
The Jujuy model combines public control with openness to foreign investment and has been among the most dynamic in bringing projects into production. The flip side is that strong state involvement requires clear shareholder agreements and predictability in the public-private relationship, something operators value especially in long-maturing projects.
Salta: predictability and a pro-investment profile
Salta has positioned itself as the province with the most decidedly investment-friendly stance. It does not have a state company holding equity stakes on the scale of JEMSE, and its strategy relies more on facilitating project development, streamlining permits and firmly adhering to national incentives, including the RIGI, which offers thirty years of fiscal and exchange-rate stability to large investments.
The result is a diverse project portfolio, with operators of various origins in basins such as Salar de Rincón and Centenario-Ratones. For investors, Salta is often read as the framework with the least direct provincial state intervention, in exchange for more open competition for the best assets.
Catamarca: mining tradition and YMAD
Catamarca brings the deepest mining tradition of the three, with the Salar del Hombre Muerto as one of the historic sites of Argentine lithium production. The province manages its policy through a robust mining secretariat and has Yacimientos Mineros de Agua de Dionisio (YMAD), an inter-state entity with provincial, national and university participation, though its role is more visible in other minerals than in lithium.
Catamarca has sought to incorporate value-added clauses and local supplier commitments into its agreements with operators. Its challenge is to balance attracting new investment—amid an expansion of installed capacity—with demands for territorial development and the socio-environmental tensions surrounding water use in the Puna.
Royalties: the same ceiling, different applications
On royalties, all three provinces operate within the limit set by national legislation, which establishes a 3% cap on the pit-mouth value. In practice, none departs significantly from that ceiling, but differences appear in the calculation base, the allowable deductions and the complementary contributions each jurisdiction negotiates: infrastructure funds, social trusts or equity stakes like JEMSE's in Jujuy.
When analyzing a project, the effective burden is not captured by the nominal rate alone, but by the sum of royalties, provincial contributions, municipal fees and RIGI conditions. Two projects with the same formal royalty may face notably different cost structures depending on the province.
The Puna as a system: coordinating without uniformity
Beyond their differences, Jujuy, Salta and Catamarca share the same geography: the Puna, with relatively low-cost brines, extreme altitudes and a scarce, sensitive water resource. All three provincial frameworks ultimately face common challenges in water management, social license and supplier development, opening space for coordination bodies such as the Lithium Roundtable.
Understanding these three regulations is not an academic exercise: it is the key to deciding where and how to invest in Argentine lithium. The country's competitive advantage will depend, to a large extent, on whether the diversity of provincial rules translates into complementarity and predictability rather than fragmentation. That is the real test of mining federalism applied to the strategic resource of the century.
