The easy story says Salta lacks local suppliers. It is false, and refuted by two independent routes: the provincial roll has 498 valid registrants and the largest operator in the copper ring already directs 86% of its spend to the province. The gap is a different one and it is better: nobody produces the proof. Five rules set five percentages on five different bases and none is comparable with another — and you do not have to take our word for it: the three national resolutions that approved projects in this very province treated the same 20% in three different ways. Diablillos declared 55% of the investment amount, Sal de Oro II declared 21.02%, and at Rincón the percentage simply does not appear in the instrument. These are acts of State on all three projects, not self-reports by the interested party. Moreover, the environmental condition is accredited every two years, project by project; and there is no third party in the province that measures the two baskets, reconciles them and signs. It is a certification market, not a supplier substitution market — and it is the only one in the province that sells equally to lithium, to gold and to copper.
The number is not a percentage of mining spend: it is the fee for certifying, documenting and auditing who supplies — the procedure, not the purchase the procedure enables. It is built in four blocks that are not the same business, and the biggest is also the most fragile.
This niche's driver is provincial and it is three rules that do not read the same way. One creates the obligation and the register, another opens a tax window with a date, and the third splits the business across two jurisdictions. The ones below open in the reforms panel on the home page, with their status and primary source.
enablesSalta: 70/60 local mining procurementIt is the door and the clock at the same time. Its section 16 defines a local supplier with four hard filters — actual or corporate and tax domicile in Salta, at least 80% of the payroll actually domiciled in the province and 51% or more of the capital in partners domiciled here — and leaves the way out written in for the outsider: a joint venture with a Salta partner from 30%. The teeth are in section 20, because it runs through the environmental licence: it requires a progressive system of between 40 and 70% of its total payroll to be set, evidenced at every biennial renewal. Careful with the 70% of section 17: the text says «preferentially», so it is a preference and not a quota — this calculation does not use it as a base in any block.see the reform →enablesSalta cuts the rate 20% for retail and hospitality, and exempts newly registered taxpayers for 12 monthsIt opens the window that finances the entrant's year one, and it puts a date on it: a new taxpayer registering voluntarily pays a zero rate for up to twelve months, and the benefit expires on 31 December 2026 unless extended by the Executive.see the reform →touchesSalta ratified first, and its Gazette publishes the annex that Catamarca’s does not: the 50/50 split is there in writingIt creates the bi-provincial block and also its off switch.

The agreement itself is declared a reference base for future projects in the border area, but it ceases to have effect once Congress settles the boundary between the two provinces.see the reform →This market does not float on its own: concrete megaprojects drive it.

It is the competitor to name first, and it is not a services company: it is the client itself resolving it in-house. First Quantum reports that it directs 86% of its total spend to suppliers in the province of Salta prob trade press on its 2025 sustainability report, May 2026, with some 40 community suppliers prob same source and more than 200 regional ones prob same source. Ganfeng reports 57% local contracting unconf company statement against a 50% minimum set in its own environmental licence unconf ibid.. Eramine reports that 87% of its 2022 investment went to local purchases and subcontracting unconf company statement, 2023 figure. And Sal de Oro II committed 21.02% verif national resolution published in the Official Gazette on 31-Jul-2026. What matters most in this entry: all five numbers are produced and published by the interested party itself, on five different bases, and none has third-party verification. That is where the business is, and that is also its fragility: whoever does it for themselves today can keep doing it for themselves.
Registration on the Provincial Registry of Local Suppliers to Mining Companies is free and public by mandate of section 15 of Act 8164 verif text of the act opened in Salta's Official Gazette, it is done online since November 2021 verif resolution 78/21 of the Secretariat of Mining and Energy and the certificate is valid for 2 years verif section 21.6 of the annex to implementing decree 534/20. Since August 2025 there is also an on-site data cross-check at the mine that validates the certificate's validity and calculates the local participation percentage on the spot prob official provincial press. And verification of compliance with the 70% is expressly the responsibility of the energy and mining resources agency verif section 22 of the same annex. WHAT THE STATE DOES NOT do, AND IT IS THE WHOLE business: it does not structure the supplier so that it qualifies, it does not issue an independent report the operator can show, and it does not reconcile the five calculation bases the rules themselves left open.
It has 316 member companies verif institutional directory opened and counted one by one. The cross-check against the official roll gives around 100 companies present in both registers verif our own nominal cross-check and shows that 80% of the official roll is not in the chamber verif same cross-check: treating the chamber as if it were the roll, which is what the press does, is a 4-to-1 error estim our own calculation over the two rolls. It publicly denounced foreign companies posing as Salta firms and all it obtained was the right to file NON-BINDING observations in registration files prob statements by its president, August 2025. It organises the procurement rounds: more than 130 companies with Rio Tinto in April 2026 prob Salta press and more than 100 with POSCO in March 2026 prob the chamber's own communication. For an entrant it is the cheapest door to the 6 to 10 buyers of the big block prob our own count of holders with a project in construction or operation.
It declares around 70 active members prob national press, October 2024, but only 9 rows of the official roll declare it as their chamber prob our own count over the roll. That gap is the finding and it has a geography: most Puna suppliers are NOT approved under the local content regime, and they are precisely the ones living where there is no alternative demand to mining. Made up of indigenous peoples of the Puna, it has already taken in members from Jujuy and Catamarca prob same source.
On the official roll there are 107 registrants declaring themselves as Consultancies and 300 declaring themselves as Services verif count over the 500 rows of the roll. It is real competition for the tax block and none for the rest. And there is a detail that explains why the speciality is invisible: the register's own 24-category schedule has no category for regulatory compliance or for local content auditing verif roll schedule, so the regime is BLIND TO THE speciality even when the supplier is registered. The same defect was already proven with laboratories and geomembranes: they exist, they are registered, and the roll cannot find them.
The technical valuation report for works offset against royalties is legally reserved to universities or intermediate bodies verif sections 9 et seq. of the annex to implementing decree 534/20. It is the only segment of the business a private firm cannot enter head-on, and that is why it is worth having them as partners. The commission that declares works to be of public benefit has 7 seats, all unpaid, and includes a seat for the legally constituted indigenous communities verif same annex.
A negative finding declared rather than omitted: not a single firm was found offering registry approval, local content auditing and mining tax compliance packaged together in Salta unconf our own survey of local supply. There are international consultancies working in the province in engineering, geology and hydrogeology, but none with a verifiable own office dedicated to this service unconf same survey. And the parent companies' sustainability reports are assured outside Argentina: what does not travel from London or from Seoul is the fieldwork of verifying between 200 and 350 suppliers against four provincial filters, one by one estim our own calculation over the purchasing bases the operators declare.
Foreign companies posing as Salta firms to get inside the regime's preference, publicly denounced by the suppliers' chamber prob statements by its president, August 2025. It is real demand a serious entrant cannot take, and turning it down costs revenue. The risk is not only reputational: section 3 of Act 8164 excludes from every benefit anyone with enforceable debt to the Province or in breach of promotion contracts verif text of the act opened in Salta's Official Gazette, and the data on the registration form have the character of a sworn statement verif section 21.4 of the annex to implementing decree 534/20. Whoever signs, answers for it.
The registry paperwork is not a business, and it is worth knowing why: registration is free, it is done online and the State itself cross-checks the on-site payroll and computes the percentage on the spot — if the service were that paperwork, this market would be worth zero. But there is paperwork that does get paid, and it is step 1: the exemption that takes mining extraction to a zero turnover-tax rate does not apply automatically. If filing is your capability, year one starts there; from there you move up to the proof, and it is worth doing it in this order:
The paper nobody filed — small ticket, high volume and it is what finances year one. The exemption that takes mining extraction to a zero rate of turnover tax does not operate automatically: you have to apply for the certificate, have no final debt or omitted tax returns, and evidence a valid mining producer certificate, whose registration costs ARS 10,800. The difference between filing it and not filing it is three quarters of a point of gross revenue, every month and on everything you bill.
Qualifying, and there are TWO distinct clients almost nobody separates — the barrier the law itself designed, and the door the law itself left open. The outsider: the 51% of capital in partners domiciled in the province is what an out-of-province supplier cannot meet without restructuring, and that is why people pay to have it resolved. The way out is written in the same text: a joint venture with at least one Salta partner holding a minimum 30% interest. Nobody is putting it together systematically, and whoever does it once replicates it across five salars. And the insider, which is measured volume and a small ticket: the Puna suppliers' chamber, based in San Antonio de los Cobres, declares around 70 active members and only 9 rows of the official roll declare it as their chamber. That gap has a geography: most of the suppliers living where there is no alternative demand to mining are not approved. They are the ones who most need the service and the ones no entry ladder names.
Bi-provincial compliance — a rule from January 2026, with no publicity, no joint implementing rules and with quantifiable damage. Invoicing to Sal de Oro or to Diablillos is not invoicing to Salta: it requires registration in both jurisdictions, attribution of income and expenses in equal parts, withholdings paid half and half and the stamp tax split in half. The text says expressly that whoever is not registered in both loses the apportionment and overpays.
The reconciliation of the five bases, sold as a subscription — the niche's best-margin product and the one with zero marginal cost, because the input is compiled once and sold many times. Nobody today has in one place the 70% of the annual amount contracted from registrants, the 60% of the payroll, the 40 to 70% progressive split into two baskets as an environmental condition, the 20% of the national regime and each operator's self-reports on its own bases. The input is entirely in public acts and nobody compiled it. And it sells on both sides of the counter: to the operator that has to report and to the supplier that needs to know whether it qualifies and what qualifying is worth to it.
The independent local content report — the highest ticket, and the one to earn last. The operator needs the number for three things in which it is judge and party: renewing its environmental licence, opening the offsetting of up to half the quarterly royalty with works, and publishing a defensible figure in its sustainability report. A third party that measures the two baskets separately, reconciles them with the five legal bases and signs, does not exist in the province today.
~USD 0.7-0.9 M/year (45-58% of the midpoint), with four capture sources and the first takes almost all of it. (a) the operator's in-house team: that is where today's published 86%, 57%, 87% and 21.02% come from. Rio Tinto, POSCO, Ganfeng, Eramet and First Quantum have procurement, sustainability and legal departments with more than enough capacity to produce the report in-house, and today they do. It is the market's hardest captive share and it has to be said head-on: the big block's demand is inferred from the regime, not observed in a contract. (b) THE STATE, free: a register at no cost, online registration and an on-site data cross-check at the mine that validates validity and calculates the percentage on the spot; the whole registration verification layer has a public substitute at no price, and that puts a low ceiling on the approval ticket. (c) universities and intermediate bodies, by a legally reserved role in the technical valuation of works that offset royalties: it is not contested, it is subcontracted. (d) the group's global auditor, which assures the sustainability report outside Argentina. Honest flip side, and it is the one that leaves the addressable market open: what does NOT travel from London or from Seoul is the local fieldwork, which is verifying between 200 and 350 suppliers against four provincial filters, one by one and with the paperwork in view.
~USD 0.45-0.80 M/year, midpoint ~USD 0.60 M/year, addressable by a local or national entrant: approval and recertification to the Registry, corporate and payroll structuring to qualify (including the joint venture with a Salta partner at 30%), verification of Salta supplier status over the operator's purchasing base, accreditation of the progressive system when filing the environmental study and at its biennial renewal, the waiver for lack of local supply, rate classification, the exemption certificate and bi-provincial compliance. It is the layer that needs to be in Salta, to know the four filters and to be able to walk to the Secretariat. BEWARE THE 70%, THE 60% AND THE 21.02%, AND HERE THE CAUTION IS twofold: the 70% of section 17 is a preference and not a quota; the 40 to 70% of the environmental condition is enforceable, but each project's specific percentage lives inside its Environmental Impact Statement and is not public; and the 21.02% of Sal de Oro II is a commitment on the investment amount, not on this line of business. All three enlarge the addressable market because they create the obligation to measure and to prove, which is exactly what is being sold, but none is guaranteed demand for fees. Confusing the audited percentage with the auditor's market is the classic and specific error of this business.
USD 0.12-0.29 M/year for ONE entrant within 2 to 3 years. CORRECTED ON 2026-08-03 FOR TWO INDEPENDENT DEFECTS, AND neither moves THE TAM. First, the ratio was not what it said: the draft declared «between 25 and 40% of the addressable market» but 0.15-0.45 against an addressable market of 0.45-0.80 (midpoint 0.60) actually gives 25-56%, and the ceiling required a single entrant to take more than half the market. Second, and this weighs most: the wedge included operator engagements that this niche's own funnel had already declared captive — the operator's in-house team is capture source (a) and takes almost all of it — meaning the wedge was eating market it had itself declared unreachable. A wedge cannot be larger than the addressable market it comes from, nor contain what the funnel subtracted. The corrected wedge is the real 25-40% of the addressable market, now net of the captive share. The percentage is high because the market is small and has no specialised incumbent: the first to arrive with the product built takes a large share of something modest. Realistic, staged composition: (year 1) the tax and registry layer, with no investment at all - 40 to 80 approvals and recertifications, 40 to 80 classifications and certificates, and the bi-provincial compliance handbook, USD 60,000-140,000 a year with 2 to 4 professionals; it is one of the CHEAPEST ways into all of Salta mining — alongside hydrogeological consulting and the well measurement file — because there is no equipment, no altitude, no heavy approval process and the client is a twenty-minute drive away. (year 1-2) the first operator - one or two annual measurement and reporting contracts, USD 80,000-250,000 a year; you get in through the chamber or through a small engagement, typically a waiver for lack of local supply, which is what an operator tests a new supplier with. (year 2-3) THE PACKAGED PRODUCT - the reconciliation of the five bases sold as a subscription, the structuring of mixed joint ventures between operator and community entity, and the local content chapter of the environmental study and its biennial renewal, USD 60,000-150,000 a year. It is a 6 to 15 person firm, mostly degree holders, based in the city of Salta. It is not a unicorn and does not pretend to be: its real advantage is that regulatory knowledge, once built, replicates to every biennial renewal at zero marginal cost.
It is the market with the lowest employment per dollar billed and the highest formal qualification in the whole chain, and both things have to be said together. Over the addressable market it is on the order of 10 to 25 direct jobs in the province estim - a fraction of what catering leaves for the same dollar billed. In exchange they are urban, office jobs, in the city of Salta, WITHOUT ALTITUDE, without fourteen-by-fourteen shifts and without seasonality: it is the only market in this ecosystem where someone with school-age children can build a mining career without going up to 4,000 metres or living in a camp.Concrete trades and professions. From the degree band: certified public accountant registered in Salta - and the provincial registration is not a detail, it is a requirement of the law itself to count as local payroll -, corporate and employment lawyer, because the joint venture with a Salta partner at 30% and the 51% of capital are company law and not form-filling, local content auditor, a role that today does NOT exist under that name in the province, and business administration graduate for the analysis of the purchasing base. And from the trades band, which is the one nobody names in a business like this: file and documentation analyst, because the approval file is eleven documents with different expiry dates; social security contributions clerk, because the contributions form is the proof of the 80% Salta payroll; data analyst, because the roll is a 500-row database with tax IDs that has to be cross-checked; and procedures and registration agent. None requires a degree; all require precision.Training: there is public funding with a legally earmarked purpose and nobody is using it for this. 5% of the mining royalty is legally assigned to promotion and training, extendable by the budget act. On budgeted 2026 royalties of ARS 8,842 million that is on the order of ARS 442 million a year legally earmarked for training estim. A short, certifiable course in provincial mining compliance - the five bases, the four filters, the schedule - is exactly the kind of training that fund can pay for, and today it does not exist in the province.Local linkage: this is where the market stops being small. The second-order effect is far greater than its own employment, because this service is the machine that turns an SME from existing into countable. The numbers are measured: the nominal cross-check between the chamber's directory and the roll leaves 215 members outside the register verif our own nominal cross-check between the chamber's directory and the roll, and in the certificate numbering 420 of the 920 issued are missing, 46% verif count over the official roll: these are certificates that were issued at some point and are not valid today. That is not the same as saying 46% of companies dropped off the register, because each biennial renewal consumes a new number and the roll does not separate new registrations from renewals. Every approval is an SME that counts again inside the 40 to 70% an operator has to evidence, and therefore one it can sell to again. And there is a door the data shows and almost nobody uses: the roll admits individuals - in the catering category 9 of 22 surveyed are - so an individual entrepreneur from the Puna can register without incorporating a company. The Puna chamber declares some 70 members and only 9 rows of the roll mention it: there is an approval gap there with a name, a surname and a geography.What is not resolved, said head-on:(1) the big block's demand is inferred, not observed. Not a single contract was found of a Salta operator paying for an independent local content audit. We know the obligation exists, because it is written in the act, the decree and the resolution, all three read; and we know that the numbers circulating today are produced by the interested party itself. What we do NOT know is whether anyone is willing to pay to prove them. It is the central weakness of this calculation and it is not disguised.(2) The price is not measured in any block: there is no public contract or bid document with a fee for this service, and although the professional council publishes and updates quarterly the value of the minimum fee unit — ARS 17,500 since July 2026 — verif resolutions of the council itself, it does not publish how many units a local content audit is worth; the nine unit prices are declared assumptions. The market can be sized; the business cannot yet be sized, and that is the difference between this document and an investment plan.(3) THE 70% is not an obligation, and that shrinks the market relative to the headline; it is said here and repeated in the risks because it is the refutation that already knocked down an earlier version of this thesis.(4) The tax block's universe could not be settled: it was not possible to find how many mining producers are registered on the provincial register, which is the denominator of the exemption certificate; that block was calculated on an assumption and is the weakest of the nine.(5) The roll used as the universe has measured quality problems: the activity field is free text and 36 of 500 rows, 7.2%, declare a category the schedule cannot read, and the schedule itself has no categories for laboratory or for geomembranes, so there are registered companies the regime cannot see by speciality. Any measurement built on that roll inherits that blindness, including this one.(6) The registration flow could not be separated between new registrations and renewals, because the roll does not publish the distinction; everything was treated as an approval event, which is defensible, but the real mix is unknown.(7) A single client can wipe out 15% OF THE MARKET by hiring one person.(8) Part of the real demand is illegitimate: some seek to manufacture Salta status rather than evidence it. This calculation does not count it, but it exists, it competes from below, and saying otherwise would be selling smoke.
Concentration It is the only market in the set with the structure inverted: demand is concentrated and supply is atomised. In drilling or in catering there are many buyers and few capable suppliers; here there are 8 to 10 buyers who know each other and hundreds of undifferentiated consultancies. The price is set by the buyer, and the seller has nothing to differentiate itself with except regulatory knowledge.Three segments with opposite structures, and the entrant who does not separate them picks the wrong business.Segment 1 - the operator's audit: hyper-concentrated demand, zero specialised supply. There are 6 to 10 holders with a project in construction or operation, all members of the same chambers and all with the same environmental consultancy on hand. There is no tender, no bid document and no public register of awards, so any concentration index would be invented. What can be stated: losing one client is losing between 10 and 15% of the business. It is a market of reputation and access, not of price.Segment 2 - the supplier's approval: demand atomised across some 245 registration events per year over a roll of 498 valid registrants, with an unbeatable competitor on price, which is the State itself and is free. Here the margin is NOT in the paperwork but in the structuring: 51% of the capital in Salta hands, the joint venture with a local partner at 30%, 80% of the payroll actually domiciled in the province and the registration of technicians with the provincial professional association. That is company and employment law, not form-filling.Segment 3 - tax compliance: saturated, generic supply (107 consultancies and 300 services companies registered on the roll), diffuse demand, and the only differentiator is knowing things that are written down and nobody has compiled: that the turnover tax exemption is not automatic, that lithium is taxed under the code for minerals for chemical products and not under a metal ore one, that repairing a network pays 5.00% and building it 2.50%, and that invoicing to the area shared with Catamarca requires registration in two jurisdictions or the apportionment is lost.What should not be sold as a gap, said head-on: that Salta lacks local suppliers is FALSE and already refuted by two independent routes. The largest operator in the copper ring directs 86% of its spend to the province, and the official roll has 498 valid registrants plus some 215 active companies that are not even on it. The gap is not one of existence or of volume: it is one of proof.
The obvious name — «the mining company» — is not a single door. Here there are three different clients, with three pockets and three sales cycles:
The 6 to 10 holders with a project in construction or operation in the province. It is the highest ticket and the slowest sale — 12 to 24 months to the first annual contract — and you get in through a small engagement: typically the waiver for lack of local supply, which is what an operator tests a new supplier with. The obligation that generates it is written in the law; the contract that pays for it has not yet been observed.
Some 245 registrations a year over a roll of 498 valid registrants, plus some 215 companies active in the sector that do not even appear on it. The register is free and online: what is charged for is assembling the file — eleven documents with different expiry dates, with the character of a sworn statement — and above all restructuring the company to meet the 51%.
Here the rate is demand and not only cost: extracting pays 0.75% and as little as 0% with a certificate, providing mining support services pays 3.60% with no permanent exemption, building 2.50%, transporting hazardous goods 2.00% — and repairing an electricity, gas, water or telecommunications network pays 5.00%, twice as much as building it and the most expensive line in the chain.
This is not «what breaks it»: it is the dashboard for getting in at the right moment. In this niche the warning does not come through the Gazette but through the roll itself, which is public and can be counted without anyone's permission.
Every registration is an SME that counts again inside the 40 to 70% an operator has to evidence, so the registration flow measures demand for the service before any contract appears. And the same roll shows where the gap is with a name and a geography: some 215 member companies of the suppliers' chamber do not appear on it, and the Puna chamber declares some 70 members against 9 rows of the roll that mention it.
Provincial Registry of Local Suppliers to Mining Companies — public roll of the Secretariat of Mining, continuously updated ↗Two companion signals, and both have dates. The biennial renewal of each project's environmental impact study, which is the business's structural clock and does not depend on any price cycle. And the tax window that is closing: a new taxpayer registering voluntarily pays a zero rate for up to twelve months, and that benefit expires on 31 December 2026 unless extended.
It is killer number one and it is the one that already knocked down an earlier version of this thesis. Everything rests on an adverb verif text of the act opened in Salta's Official Gazette: section 17 says mining companies shall preferentially contract local suppliers listed on the register in a share of no less than 70% of the total annual amount contracted verif same text. The adverb downgrades the obligation to a preference. Only two sections have teeth: section 20, because it runs through the environmental licence verif same text, and section 19, which opens the offsetting of up to 50% of the quarterly royalty only to whoever complies with and maintains sections 17 and 18 verif same text. PRACTICAL CONSEQUENCE: an operator with an environmental licence already approved and no intention of offsetting royalty has no enforceable obligation to buy locally. Whoever sizes this market as a fraction of the province's mining spend is quantifying a preference as if it were a mandate.
First Quantum reports 86% of total spend to Salta suppliers prob trade press on its 2025 sustainability report, May 2026; Eramine reports 87% of its 2022 investment unconf company statement; Ganfeng reports 57% local contracting unconf company statement. If those numbers are correct, the help-me-comply market is small. What remains is prove-it-to-me, which is smaller still, and today not a single contract was found of a Salta operator paying for an independent local content audit unconf our own search with no result. The big block's demand is inferred from the regime, not observed.
Registration on the register is free and public by law verif section 15 of Act 8164 opened in Salta's Official Gazette and is done online since November 2021 verif resolution 78/21 of the Secretariat of Mining and Energy. Since August 2025 there is an on-site data cross-check at the mine that validates the certificate's validity and calculates the local participation percentage on the spot prob official provincial press. A free public substitute puts a low ceiling on the approval ticket, and that is why that block is worth barely USD 0.04 M a year at its midpoint estim our own calculation. The margin is in structuring, not in filing.
Salta acceded to the national regime with an act of exactly 2 sections: it accedes and it notifies verif text of the act opened in Salta's Official Gazette. It has no local content clause, it does not stabilise provincial taxes and it makes no reference to the provincial mining act verif same text. If it is settled that provincial local content is not enforceable against a holder with the 30-year regulatory stability the national regime grants verif Title VII of Act 27,742, the operator audit block shrinks abruptly. HONEST COUNTERWEIGHT: while the uncertainty lasts, it is itself demand for advice, and the chambers have already raised the point publicly.
The agreements creating the obligation to register in both jurisdictions cease to have effect once the National Congress settles the boundary dispute verif text of the agreement published in Salta's Official Gazette on 09-01-2026. That switches off the bi-provincial block, which is worth USD 0.10 M a year at its midpoint estim our own calculation. COUNTERWEIGHT, and it is also textual: the protocols are declared a reference base for future mining projects located in the border area verif same text, so the regime survives the project that gave rise to it.
This service is a professional activity and has no escape: it pays 3.60% turnover tax with no permanent exemption verif schedule of activities of Salta's Directorate General of Revenue, and it makes no difference whether it is classified as a professional, scientific and technical activity or as a mining support service: both rows say 3.60% verif same schedule. It has neither the 2.00% escape door of transporting goods and hazardous substances nor the 2.50% of construction verif same schedule. Meanwhile mining extraction pays 0.75% and as little as 0% with an exemption certificate verif ibid.: that is 4.8 times the mine's rate. Add the services contract stamp tax at 12 per thousand, that is 1.2% on the amount prob our own reading of the consolidated provincial tax act. On a business whose cost is almost entirely payroll, that rate on gross revenue is structure, not nuance.
The suppliers' chamber declared its members operating at 40% of capacity, with a cumulative fall of 60% in 18 months prob statements by its president, August 2025. Salta mining employment fell 5.7% year on year as of March 2026, to 5,569 jobs verif monthly report of the Secretariat of Mining: it is the only one of the seven large mining provinces that fell, while the country added 1.2% and the lithium segment 6.5% verif ibid.. A supplier working at that fraction of capacity does not buy consulting: it cuts first whatever it does not bill to the client. The approval and tax compliance blocks are pro-cyclical and the operator is counter-cyclical, so the portfolio has to be built with both.
There are 6 to 10 buyers in the whole operator audit block prob our own count of holders with a project in construction or operation. Any of them can internalise the complete service by hiring ONE person, and the contract disappears. It is not a theoretical risk: it is exactly the current state of the world, and this calculation assumes it begins to reverse. It may not reverse. Losing one client is losing between 10 and 15% of the business estim our own calculation over the universe itself.
The chamber publicly denounced foreign companies posing as Salta firms to get inside the regime's preference prob statements by its president, August 2025, and all it obtained was the right to file non-binding observations prob same source. Part of those seeking this service do not want to evidence local content: they want to manufacture it. A serious entrant has to turn that demand down, and turning it down costs revenue. This calculation does NOT count it, but it exists and competes from below.
The framework agreement with Rincón Mining that the official press reported in August 2025 was approved by a resolution 97/25 that does NOT exist in the province's Boletín Oficial verif as an absence, searched in the Boletín's four search engines. A business that sells itself on documentary traceability has to say that the regime's flagship act is not traceable, and that therefore the progressive local-participation plan of the province's largest project cannot be read anywhere. The same goes for each project's local-content percentages: the implementing decree orders them to be recorded in the Environmental Impact Statement verif article 26 of the annex to decree 534/20 and as of the Aug-2026 cutoff we did not find a single statement publishing its own unconf own search with no results.
The legal investment deadlines expire in 2029, on 30 June and 31 July depending on the project verif resolutions published in the Official Gazette. It is among the markets with the least cliff edge in the whole set: the supplier certificate is renewed every 2 years forever verif section 21.6 of the annex to implementing decree 534/20, the environmental study is accredited at every biennial renewal verif resolution 96/20 of the Secretariat of Mining and Energy, the exemption certificate expires with a five-year cap and is renewed verif section 174 bis of the Fiscal Code, and the Multilateral Agreement is filed every month. What does switch off when that window closes is the structuring peak associated with construction.
The TAM is built by counting obliged clients times fee, never a percentage of the spend being audited: counting the audited spend would mean counting the province's other services markets again in full. There are three variables that can be monitored, and one of them anyone can count, because the roll is public.
A robustness check along three paths, and the honest result is that only one bites, and only over 15% of the total. (a) Descending from the registry, which is the strong path because the universe is public. The Law 8164 registry has 498 current registrants. The price has a datable floor from inside the province: the minimum-fee module of the Consejo Profesional de Ciencias Económicas de Salta is worth ARS 17,500 as of July 2026 —the year's series runs 14,800 in January, 16,100 in April and 17,500 from July, with quarterly revision— which at the exchange rate the calculation declares (1,450-1,500) comes to about USD 12 per module. A modest annual engagement to keep the file current —20 to 60 modules— gives USD 235-725 per registrant per year; across the 498, USD 0.12-0.36 M/yr. The published block A (the supplier that has to qualify) is 0.06-0.63, centre ~0.24: the descending path brackets it. But that block is 0.24 of 1.56, that is 15% of the headline: the other four are left with no second path. (b) The counterpart in another province, and it is weak for a concrete reason. The certification niche in Neuquén publishes ~USD 1.5-3.5 M/yr (midpoint ~2.5) for some 49 obligated companies, but it has no formula and no declared result —it is a prose estimate with no auditable arithmetic— so leaning on it imports its weakness. Taken anyway, the two normalisations point in opposite directions: per obligated company, Neuquén implies ~USD 51,000 a year and what is published here is ~USD 200,000 across ~8 operators, almost 4× more; by registry size —498 registrants here against 417 firms in the Neuquén registry as of April 2026— this one gives USD 3,200 per registrant against USD 6,000 there, that is half. When two normalisations of the same counterpart contradict each other, the counterpart does not discriminate, and the reason is that the two niches count different universes: here the obligated operator is counted and the registry and the tax portfolio and the royalty works; there, only the obligated company. It is declared and not used to move the figure. (c) The weight within the province: not available. This is the path that did work for metrology, because it had a sibling pair in Catamarca with a measured control. Here the only peer that exists is Neuquén's, already used in (b), and it does not work as a control because it publishes neither a formula nor a result: so along this path too there is nothing to contrast the 0.7% this market weighs against the USD 229.3 M/yr of Salta's nine niches. What stands: the registry block is corroborated by an independent path priced from a public source; the remaining 85% of the headline rests on the method and on the fee assumption, not on a second path. It is the largest verification gap this market has left, and the shortest route to closing it is a single invoice or tender for a local-content accreditation service in the province.
The number rests on a few variables. The formula shows how it moves when each one changes; and each variable carries its freshness seal — how often it is worth revisiting. estim
Every figure is checked against its source before we publish it. Here we show what backs it — and where the verified data ends and our estimate begins.
The hard anchor is the rule, and it was read in full in the Official Gazette: section 20 of Act 8164 requires a progressive system of between 40 and 70% to be set, and the clause closing the sentence — «of its total payroll» — is the one that declares the calculation base. The resolution implementing it splits that obligation into two separate baskets, employment on one side and services, works, goods and inputs on the other, and requires them to be evidenced when the environmental impact study is filed and at its biennial renewal: that is the business's clock. The roll is also measured, countable data: 498 valid registrants, with 160 registrations in 2024 and 197 in 2025, and 143 already counted in the first seven months of 2026 — meaning the flow is not easing off. What is estimated is declared and can be subtracted: there is no published fee for this service — the professional council publishes the unit value, ARS 17,500 since July 2026, but not how many units measuring local content is worth — and the largest block, the independent report to the operator, has its demand inferred from the regime and not observed in a contract. That is why the number is published with the cut already made: without that block the market is worth ~USD 1.0 M/year instead of 1.6.
