What changed and who it applies to
What changed
It created the Register of Suppliers to Mining Companies (Re.P.E.M.), under the Provincial Directorate of Mining Social Promotion, described as "public and mandatory for all relevant companies". It has TWO halves worth keeping apart. (A) the obligation on the miners, article 4, verbatim: "the total number of annual contracts for works, services, purchases of goods and/or inputs from suppliers registered in the Re.P.E.M. shall not be lower than seventy per cent (70%) of total contracting with suppliers". It is the only instrument that reserves a provincial quota: unlike the RIGI, where "local supplier" means Argentine, here the supplier must be domiciled in Catamarca. (B) the requirements to register, article 5:(1) actual and legal domicile in Catamarca for no less than 2 years and the main seat of business within the province;(2) in a company, 50% of the legal entities, partners or shareholders domiciled or registered in Catamarca;(3) a joint venture "shall be composed at least fifty per cent (50%) of local suppliers";(4) municipal licence and registration as a taxpayer with the provincial revenue agency;(5) proof of existence and domiciles with the registered constitutional instruments;(6) that 70% of professional, technical and/or administrative employees be natives or residents of Catamarca for no less than 2 years;(7) a sworn statement on the Annex I form;(8) updating the data every six months. Article 9 adds annual renewal before 30 March. The resolution expressly excludes "mere intermediaries", and Annex I requires proof of membership in the corresponding Chamber of Suppliers: chamber membership is a requirement of the register. A declared limit of the published rule: article 4 says "total number of contracts", which read literally is a count of contracts and not an amount, and the resolution does not settle it. verif · Jun 23, 2014 ↗
In force
23 June 2014. Catamarca's official Mining Legislation portal lists the rule as "In force" as of 28 July 2026, and the register is still open for registration. verif · Jun 23, 2014 ↗
Who it affects
SMEs and suppliers based in Catamarca that want to sell to the lithium miners (Rio Tinto/Minera del Altiplano, Zijin-Liex, POSCO, Galan, Albemarle) and the copper miners (MARA), and to companies from other provinces, which stay out of the register unless they establish themselves locally or come in through a joint venture with a local firm. As of July 2026 the register has 229 active suppliers, with a series running from 31 (2022) to 112 (2023), 194 (May-2025) and 229 (May-2026); the 2025 distribution concentrates 75 of 194 in the provincial capital and only 12 in Antofagasta de la Sierra, the department where the producing lithium sits. prob · May 2026 ↗
The norm
Resolución N° 498/2014 of the Secretaría de Estado de Minería de Catamarca (the provincial mining secretariat). A SUB-STATUTORY instrument: unlike San Juan (Ley 8.421/2013), Salta (Ley 8.164/2019) and Santa Cruz (Ley 3.616/2018), Catamarca's mining local-purchase regime does not carry the rank of a provincial law and can be amended or repealed by another resolution of the same secretariat. Jujuy has no such instrument. Issued and enacted on June 23, 2014 (case file S-13331/2014), signed by the Secretary of State for Mining under the powers of Decretos Acuerdo 1544/07 and 1193/02. verif · Sep 2023 ↗
Our reading
For the satellite supplier, Catamarca has the cheapest door and the flimsiest lock in the NOA. Cheap: the Re.P.E.M. requires no technical certification and no minimum capital — it asks for a 2-year domicile, 50% local partners, 70% local payroll and a sworn statement every six months. An SME from another province gets in through a joint venture with a local partner (50%) without relocating. Flimsy: the whole regime is a secretariat resolution, not a law — it can be changed by another resolution, which is why suppliers went public saying "the Re.P.E.M. is not to be touched". The practical consequence is that the commitment with the most force TODAY is not the provincial one but the one in the RIGI filing: Fénix's Resolution 431/2026 estimates 60% of the investment going to suppliers and Hombre Muerto Oeste's 1271/2025 estimates 95.34% verif, both under national enforcement authority. With small print that matters: under the RIGI "local suppliers" means Argentine, not from Catamarca. The strictly provincial quota is the one the Re.P.E.M. gives, and that is why its sub-legal rank is the real weak point of the package. thesis
Where it lands, province by province2
Catamarca It is the lever that turns 'being from Catamarca' into a selling advantage: registering in the Re.P.E.M. is the entry procedure to a market that opens the lithium portfolio. The cost of entry is administrative (domicile, partners, payroll), not technical or capital — the real barrier is in the lines of business the province does not have (metalworking, process chemistry, instrumentation, certified laboratory, geomembranes, EPC), not in the register. favorable thesis
