WhenWhat is bought in 2026 is construction close-out:
Fénix 1B and Sal de Vida achieved first production in the second quarter and are still in start-up. And the consultants' registry
is called once a year, in the first quarter.
thesis The main barrierGetting cleared in time. The consultants' registry is called once a year and the suppliers' registry asks for
two years of domicile. The rule allows a joint venture with at least half local suppliers: whoever arrives today gets in with a
local partner.
thesis the whole entry map → Where you get inDo not start by fighting for the basic engineering against a global firm whose reports are accepted by the banks that finance the works. You enter from the side, where the barrier is not prestige but being qualified and present when the works need it:
the 3 routes → In Catamarca four lithium projects started up in twelve months and we did not identify any that bought its engineering in the province. The names are in the primary sources: a global firm did Sal de Vida's capital estimate, one of the three signatories of the technical report works at a subsidiary of a foreign firm, and another one estimated Stage 2 verif technical report; Hombre Muerto Oeste's nanofiltration plant was assembled and tested in Sydney before being shipped prob Panorama Minero on Galan's quarterly report, Jan 19, 2026. On the other side, only the construction is Argentine, and there is a precedent that defines the path: a Catamarca construction company appears partnered with two contractors from other provinces in a joint venture listed by Catamarca's mining services chamber verif , and according to the provincial press that joint venture signed in November 2022 the engineering, procurement and construction contract for the Sal de Vida plant prob El Esquiú, Nov 17, 2022. The business is not to replace the global firm: it is to sell it hours. Detailed piping and structural engineering, as-built, document control, fabrication inspection, weld control and assisted commissioning — the layer the EPCM subcontracts and that today arrives from Rosario, from Salta or from Sydney.
A double window: two plants entered commissioning in Q2-2026 (as-built and document close-out are being bought NOW) and the construction front closes in 2029; afterwards the perpetual operating core remains, smaller and recurring.
What the market is made of
The TAM is activity, not what you will invoice. The high layer —the EPCM, the basic engineering, the technical report signed by qualified professionals, the vendor's technology package— is captive and will stay that way: it is not bought in Catamarca and it will not be. And there is a less obvious captive that is larger than it looks: the technical office the construction contractor includes in its price from Rosario, and the design the operator standardizes once and replicates. Your gap is the intermediate layer that gets subcontracted: piping and structural detail, as-built, document control, fabrication inspection, weld control and assisted commissioning.
How it splits, and against which totalMidpoint of the captive/addressable split (~60-70% captive, per the funnel) over the midpoint TAM of ~USD 9.5 M/year. Our own estimate. estim

Careful with the 95.34 % and the 60 %: they are the share of what each project pays suppliers that it declares goes to local suppliers (Hombre Muerto Oeste 95.34 %
verif; Fénix 1B 60 %, three times the 20 % legal floor
verif), not a quota for this category. The national regime's regulation counts only goods and works in that percentage, not services: an engineering hour does not go in there, and neither do transport or catering
verif. But the provincial registry requires mining companies to send at least 70 % of their annual contracting —works, services and goods— to registered suppliers, and there engineering does count
verif. That is the rule that moves demand toward this line
thesis.
Entry range for a supplierUSD 0.5-1.2 M/year for ONE entrant within 2-3 years = 11,000-25,000 h/year = a 6 to 13 person practice estim. A realistic composition: a document control + as-built contract on one site (year 1), an inspection/NDT package sold to two operators (year 1-2), a piping detailed engineering package via a joint venture with the EPC of the day (year 2-3). It is SME-sized, it is profitable and it is replicable to Salta and Jujuy — it is not a unicorn.
▸ Leverage, not a guarantee — at equal price and capability. And there is a clock specific to this line: the provincial registry requires two years of legal domicile in Catamarca, so whoever is not already inside can only enter via a joint venture while that period runs.
Who really pays?
The obvious name —«the mine»— is only one of the doors in this line. Engineering is contracted in a chain, and each link buys something different:
If you sellBasic engineering, FEED, capital estimate and the bankable technical report (NI 43-101 / JORC)
→
The operator, directly — but it buys from firms outside the province prob thesis Sal de Vida's Stage 1 capital estimate was prepared by a global engineering firm, together with Galaxy; Stage 2's, by another foreign firm; the technical report is signed by three professionals: one from a foreign hydrogeological consultancy, an independent consultant and one from the subsidiary of a foreign studies firm verif. The report must be signed by a qualified person under the Canadian mining disclosure standard verif. This door is closed and it is worth saying so thesis.

The EPCM or the winning EPC, by a subcontract of hours, and also the operating company on its own account thesis thesis Sal de Vida's technical report assumes the works are executed under the EPCM model, and its estimate includes the contractor's site technical staffing, third-party consultants and, on the owner's side, engineering and subconsultants verif. The entrant sells hours to that contractor or to the owner: a joint venture like the EPC one verif is exactly the kind of client-partner you invoice thesis.
If you sellThird-party inspection and document control independent of the builder
→
The operator, directly — because it needs an eye that is not its own contractor's thesis thesis It is a door where the operator contracts directly and where having a local office plays in your favor thesis: Rio Tinto runs its own supplier development program in Catamarca, with more than 50 suppliers trained, 800 hours of assistance and 60 % more requests for quotation verif, and the 2nd Mining Suppliers Meeting of May 2026 drew more than 500 suppliers, with Rio Tinto, POSCO, Galan and MARA among the buying mining companies prob.
▸The lesson: the engineering that decides the project is bought abroad and will keep being bought abroad; the one executed against the drawing, inspected in the workshop and closed out in the quality report is the one that does stay on this side — and today it arrives from Rosario or from Salta.

In this line engineering runs ahead of construction by 12 to 24 months, but the act of State does not always come first: Fénix 1B and Tres Quebradas got their resolution with construction already under way. What you watch are the dates each act sets and the procedure that lets you bid. The four Catamarca acts have already set their minimum-investment deadlines: Fénix Expansión Fase 1B until 1 December 2026, Tres Quebradas 2nd stage until 30 November 2027 (with 40 % of the minimum in the first two years), Agua Rica until 31 December 2028 and Hombre Muerto Oeste until 31 December 2029. Tres Quebradas started construction on 1 June 2026 and its operation is scheduled for 1 April 2029; Agua Rica builds from 1 November 2027 and operates from 1 October 2031. These dates are the ones that give notice.

What signals the game has changed
Lithium carbonate price (continuous exposure, effect within 1-2 quarters)
Today it plays in favor: the second quarter of 2026 averaged USD 22,043/t spot CIF Asia, 13 % more than the first verif Rio Tinto Q2-2026 filing with the SEC.

verif Rio Tinto Q2-2026 filing with the SEC. But engineering is the first line cut before an FID: a price reversal freezes Sal de Vida Stage 2, Kachi and 3Q's Phase 3 before it touches a plant in operation. It is the most cycle-sensitive line in the whole chain, because its demand is discretionary pre-investment spending.
The operator's centralized engineering (structural, 2026-2029)
The specific killer and the most likely one. Rio Tinto is said to want to define the best-in-class DLE standard and to standardize under the motto 'Design One, Build Many', which it writes in its lithium presentation verif Rio Tinto lithium presentation, 8-Dec-2025, and it owns 2 of the 4 Catamarca assets.
See the evidence
A replicable design eliminates the re-purchase of detailed engineering per project and turns the line from 'engineering' into 'verification and as-built of a design already done': smaller and less qualified. The flip side: the same presentation speaks of 'early EPC engagement' and 'supplier led solutions'

prob mining press, 24-02-2026. Vendor engineering travels with the equipment and site engineering travels with the contractor.
The large stage in the basket now has its act, with a computable amount that differs from the one announced
Tres Quebradas 2nd stage now has its act: the resolution was published on 29-Jul-2026 and computes USD 594,136,000 in computable assets verif Resolución 1153/2026, against the USD 710 M of committed investment published on the regime's official portal verif the regime's official portal.
See the evidence
Since that stage is 63% of the basket's capex still to execute
estim, the risk of the instrument not coming out —which sank the TAM midpoint from ~USD 11 M to ~USD 4.1 M/year— is closed for it; and the base is no longer open: the basket counts total investment in its four rows, and the act's USD 594 M are computable assets —the base of the tax benefit—, which is a different magnitude. Outside the basket, Sal de Oro II has its own as well: Resolución 1157/2026, published on 31-Jul-2026, computes USD 207,936,427 in computable assets

Ninth clause of the Sáenz-Jalil agreement (binary risk, indeterminate timing)
The 50/50 split of royalties, taxes and levies on the disputed strip of the Salar del Hombre Muerto becomes void once Congress settles the boundary, and the winning province becomes the sole authority (Salta claims 134 of the salar's 586 km2; the boundary has been undefined since the National Territory of Los Andes was dissolved in 1943).
See the evidence
A supplier registered only in Catamarca's Re.P.E.M. can end up on the wrong side of the jurisdiction that gives it the preference. A known mitigation: dual registration Catamarca + Salta — that is exactly what CaFeProMi exists for, which Catamarca chaired first.
Social license and conflict OVER CONTRACTS, not environmental (active, episodic)
In mid-June 2026 the Tinogasta mining suppliers' chamber (CAPROMITI) threatened to block the roads of Fiambalá over reports that Zijin-Liex had closed a deal with a trucking company from Córdoba.

End of the construction window vs. the perpetual operating core (A certainty, not a risk: 2029-2030)
Past the peak, project engineering falls and the recurring core remains: live as-built, plant document control, integrity inspection of tanks and piping, NDT, plant turnarounds, de-bottlenecking and brownfield work.
See the evidence
Smaller but perpetual — and Fénix's own resolution says the local supplier commitment runs 'during the construction AND operation stages'. A practice sized only for the window is out of business in 2030; the one that builds the operations line keeps the client.
Tax: the margin killer, not a demand killer (structural, with a 12-18 month window)
Ley Impositiva 5.927: turnover tax on 'Mining support services' (code 99000) = 3.0% / 3.9% / 4.8% by bracket, against 0.75% for extraction (code 89120) verif article 15 and Annex I of the Ley Impositiva.
See the evidence
plus 1.5% stamp tax on the mining supplier's purchase order and on works and services contracts (article 26 subsection 2
verif the same primary source; subsection 1 taxes at 2% the acts over mining rights and concessions, which are not the supplier's, and the 0.1 %/0.05 % fee for bidding (article 30)
verif Ley Impositiva 5927, article 30 applies only to purchases by the provincial State itself, not to the mining companies' tenders
verif ídem). In an hours business there is no cost of goods to dilute a tax on gross revenue: 3-4.8% turnover tax + 1.5% stamp tax eats ~20-30% of the bottom line
estim of a practice with a 20-25% net margin. And it
penalizes growth: crossing Bracket I (ARS 3,255,000,000 of 2025 revenue
verif article 15) raises the rate by 30%. A window: article 16 puts whoever starts activity from 1-Jan-2026 in Bracket I for their entire first fiscal year.
The opportunity in depth
How to get inthe gap and the routes that open it
1Document control and as-built. The document close-out, the as-built and the punch-list are end-of-construction work that cannot be deferred — with no quality report there is no plant acceptance unconf. Entry capital is practically nil; the barrier is method, not money.
2Fabrication inspection and weld control. The embryonic capability is already in the province: seven suppliers in the registry do hydraulic testing and thickness checks. What is missing is the inspector certified in non-destructive testing and the package sold as a third-party service. The demand is measured: Fénix's civil works contract alone includes 4, 6 and 8 inch above-ground and buried piping, a fire water network, earthing and a water pipeline.
3With proven execution, the detailed piping and structural engineering, and the vehicle that makes it possible: the joint venture with a local partner. The provincial registry admits it with at least 50% local suppliers verif, and the precedent already exists: a Catamarca construction company appears partnered with two contractors from other provinces in a joint venture verif, and another Catamarca firm built the Tres Quebradas ponds together with two contractors from other provinces prob. What they prove is that the vehicle works —not that there is an open package waiting for you. A Catamarca practice inside a joint venture does not compete with the global firm: it sells it hours.
What you needcapital, certification, tax regime and who pays
It is paid against progress and certified hours, with no dead gap. What you need in order to enter — the full map, in the open:
CapitalThe lowest in the whole mining chain: it is a business of hours, not of equipment — against the USD 20-40 M a production-well drilling rig demands. The real capital is working capital: 70-80% of the cost is monthly salary and there is no public data on payment terms from the miners in Catamarca. Add the bond you have to post to sign: surety insurance is not bought from a local supplier but from a national insurer, so what measures the market is not local supply — what decides is your balance sheet.
CapabilityISO 9001 as a floor; for inspection, staff certified in non-destructive testing level II and welding procedure qualification; licensed CAD/3D platforms and a document control system the client accepts. And altitude fitness: commissioning and inspection are done on site at 4,100-4,300 masl, with no national standard setting the medical criteria.
RegimeThe
Re.P.E.M. requires domicile in Catamarca with
2 years of seniority, 50% local partners and
70% of the professional and technical payroll from Catamarca, with a semi-annual sworn statement.
See the detail
That 70% professional is this line's specific bottleneck. On top runs the operator's own homologation. The legal way out: a joint venture with at least 50% local suppliers. And there is a second door, specific to this line, that the suppliers' registry does not cover: the Registro de Consultores Expertos Mineros y Ambientales, created in 2011, which calls for registration once a year, in the first quarter and since 2012 also requires an office in the province with at least half of its professionals and technicians from Catamarca. Mining companies are obliged to consult it every time they contract an independent professional.
Who paysIt is paid by the EPCM or the construction contractor, per certified hour, and also by the operating company, which buys engineering and sub-consultants in its own budget.
When you get paid, and what blocks it
It gets paid today, with no dead gap — and part of it is paid urgently. Four live sites: two in commissioning since Q2-2026 (Fénix 1B and Sal de Vida, first production ahead of plan) that are buying as-built and document close-out NOW, one under construction with an open front until Dec 31, 2029 (HMW) and one with construction started on Jun 1, 2026 according to its resolution (Tres Quebradas 2nd stage), whose second batch of 200 ha of ponds the contractor announced with no published date. Signals of stated demand: Rio Tinto's supplier development program in Catamarca reports +50 suppliers trained, 800 hours of assistance, 290 improvement actions, +60% in requests for quotation and a 90% acceptance rate (20-F 2025), and the 2nd Mining Suppliers Meeting (May 28, 2026) drew >500 suppliers with Rio Tinto, POSCO, Galan, MARA, Alumbrera, Minera Cordillera, AbraSilver, Albemarle, CAMYEN and YMAD seated as buyers.Commercial model (four doors): (1) a subcontract of hours to the EPCM or the EPC, time & material against an approved rate schedule; (2) a joint venture with >=50% local suppliers, the route the Re.P.E.M. itself designs, with the precedent of a Catamarca construction company in the joint venture with two contractors from other provinces; (3) a direct contract with the operator for third-party inspection, document control and as-built, where the operator wants independence from the builder; (4) secondment/staffing to the owner's team — the primary source itself describes a 'Catamarca city office' on a 5x2, 40-hour regime.The real bottleneck, in order: (1) the Re.P.E.M., and it bites differently in this line — legal domicile in Catamarca >=2 years, 50% of partners domiciled in the province, 70% of the professional, technical and administrative payroll of Catamarca origin or residence >=2 years, municipal license + Rentas and a semi-annual sworn statement (the silent filter that de-registers suppliers). The 70% professional payroll is the specific bottleneck: easy for a construction company, hard for an engineering practice in a province of 429,562 inhabitants. Practical consequence: an entrant from outside cannot register today, it has to enter via a joint venture. (2) Homologation in the operator's supplier registry (Rio Tinto runs its own portal): a parallel process independent of the Re.P.E.M. (3) Surety and insurance: the registry declares ONE (1) member in insurance for the whole province, and for engineering you add professional indemnity, a scarce product in Argentina. (4) Working capital against a figure that does not exist: there is NO public data on the miners' payment terms in Catamarca (a stated total gap); in a business where 70-80% of the cost is monthly salary, financing 60-120 days of collections is the real risk, not the capex. (5) Certification and capability: ISO 9001 as a minimum; for inspection, staff certified in NDT level II and welding procedure qualification; licensed CAD/3D platforms and a document control system the client accepts. (6) Altitude: commissioning and inspection are done on site at 4,100-4,300 masl and there is no Argentine legislation setting fitness criteria for working above 3,500 masl: each company sets its own standard prob; in the July 2026 storm, Rio Tinto workers isolated by the snow were evacuated with a helicopter brought from Buenos Aires prob.Time to first invoice: 3-6 months via a joint venture or a subcontract of hours with an already registered local firm (as-built, document control, one-off inspection); 9-15 months for a detailed engineering package of your own with full operator homologation; 24+ months if you intend to register on your own from scratch, because the 2-year legal domicile clock rules estim.

The operator's own chain: Rio Tinto, Zijin (Chinese chain) and POSCOthe entrant's real competitor, not a firm
In its lithium presentation Rio Tinto writes the motto 'Design One, Build Many', together with 'early EPC engagement' and 'supplier led solutions' verif; it owns 2 of the 4 assets (Fénix and Sal de Vida), and a replicable design is paid for ONCE and copied thesis. Zijin executes with its own chain: the Chinese-made geomembrane for Tres Quebradas came in on 16 trucks through the Paso San Francisco prob. Regarding POSCO, some attendees at a plenary session of the Catamarca mining suppliers' chamber, in Belén in February 2026, said that POSCO brought its own suppliers from Korea for the construction of its plant and that, once it was finished, it turned them into service companies prob.
The technical offices of construction contractors from other provinces40-55% of the subcontractable middle layer (our estimate)
They bring their own site engineering, planning, surveying and QA-QC INSIDE the construction price. This is the incumbent the entrant actually displaces, not the global firm.
Catamarca builder that entered through a joint ventureone of the two documented local precedents in a large package, along with another Catamarca construction firm in the Tres Quebradas ponds
It appears as the local partner of the joint venture with two contractors from other provinces in the provincial chamber's member listing verif; in November 2022 that joint venture signed with Galaxy Lithium (Sal de Vida) the engineering, procurement and construction contract for Sal de Vida's lithium carbonate plant, a USD 130 million job whose clauses give priority to hiring residents of Antofagasta de la Sierra prob. It is the template of the entry vehicle, not an engineering competitor, and it proves the door opens, not that there is a live contract today.

Add PPE (7 members, which includes 'hydraulic testing of pressure equipment, thickness checks' = embryonic NDT). The registry has NO category of its own for EPCM engineering or construction management: the gap is one of scale, certification and capability, not of existence.

How we
calculate it
The number is our own estimate. The calculation, step by step, is below.
The full calculation, step by step
Concentration Two layers with opposite concentrations. High layer (EPCM, basic engineering, FEED, NI 43-101/JORC, hydrogeology, technology packages): total concentration and 100% foreign — an effective HHI tending to 1 per package, because each project has ONE EPCM and ONE technical report author, and there is not a single Catamarca or Argentine firm documented signing basic engineering in the province.Middle layer (what the EPCM subcontracts: piping and structural detail, as-built, document control, fabrication inspection, weld control and NDT, assisted commissioning): fragmented and hollow — the Re.P.E.M. went from 31 (2022) to 229 active suppliers (May-2026) with 75 of 194 in the capital and only 12 in Antofagasta de la Sierra, and the professional services category declares 7 members against four simultaneous construction sites. The definitive share is NOT divided among the incumbents: it is decided by whether the operator internalizes the engineering and replicates it across its projects, and whether the construction contractor keeps bringing its technical office from Rosario.
The rule that moves it
The driver of this niche is twofold and pulls both ways. In favor: the Re.P.E.M. —the provincial registry of mining suppliers— reserves the market for whoever has real roots in Catamarca and admits entry via a joint venture with at least 50% local partners, while the local-content commitments in the RIGI case files (95.34% at Hombre Muerto Oeste, the highest among the Catamarca projects that disclose it estim; 60% at Fénix; 54% at Agua Rica) count only goods and works, not services: for this line, the door is opened by the provincial 70%, which does include services. Against: Ley Impositiva 5.927 charges 3.0% to 4.8% turnover tax on mining support services against 0.75% on extraction, and adds 1.5% stamp tax on the supplier's purchase order (article 26 subsection 2; the 2% of subsection 1 taxes acts over mining rights, which are not the supplier's) — in an hours business, that eats a fifth of the bottom line.

enablesRe.P.E.M.: Catamarca's mining local-content rule is a resolution, not a law
See the rule → The Re.P.E.M. (Resolution 498/2014) is the door and the filter at once. It enables: it reserves the market for whoever has provincial roots and expressly admits the joint venture with at least 50% local suppliers — the vehicle with which a Catamarca construction company partnered with two contractors from other provinces.See the full legal grounds
It filters differently in this line than in any other: it requires legal domicile with 2 years of seniority, 50% of partners domiciled in the province and 70% of the professional, technical and administrative payroll of Catamarca origin or residence, with a semi-annual sworn statement. A construction company has that 70% to spare; an engineering practice is short of the Catamarca engineer with two years of residence, in a province of 429,562 inhabitants. Practical consequence: whoever comes from outside cannot register today — they enter via a joint venture while the clock runs. And a fragility worth knowing: it is the only local-content mining regime in the country with sub-statutory rank (a secretariat resolution, not a law), and CAPPROMIN has been asking for a provincial law since 2019.
Where the number comes from
~USD 9.5 M/year at the midpoint; the band is USD 8-11 M/year, equivalent to some 200,000 man-hours a year — on the order of 100 professionals and technicians across the four sites, and that count is a ceiling. And there is an option that changes the scale: MARA / Agua Rica —USD 6,393.6 M of total investment according to its resolution, published on 27-Oct-2026; the USD 4,000 M is what Glencore announced when it filed the application— is not counted here: it is copper, it calls for a different specialty and its construction starts on 1-Nov-2027, a date the company estimates, without Glencore having published its final construction decision thesis. Its engineering is worth on the order of USD 179 M, i.e. 36-45 M/year over 4-5 years: between 4 and 5× this niche. It is not the same client —but it is the ceiling worth looking at before sizing a practice
See the calculation, the variables and how it was validated
The TAM is built from three variables you can watch: how much capex has live construction in the province, what percentage of that capex goes to engineering and control, and over how many years it is executed. Change one and the number is recalculated.
~USD 959 M of capex still to execute × 2.8-4.0% of engineering and control content ÷ ~3.5 years of construction=~USD 9.5 M/year at the midpoint; the band is USD 8-11 M/year
Capex with live construction still to execute~USD 959 M (out of USD 2,192 M nominal)annual review
Four projects, each with its declared base: Fénix Phase 1B (USD 531 M, in commissioning), Sal de Vida Stage 1 (USD 660 M, in commissioning), Hombre Muerto Oeste (USD 292 M, under construction to 2029) and Tres Quebradas stage 2 (announcement of USD 709 M of total investment; its resolution, published on 29 July 2026, counts USD 594 million of computable assets). ⚠️ The two numbers do not contradict each other: they measure different things. «Computable assets» is a RIGI term —the base the benefits run on— and it is narrower than the project's investment: in this same basket, Fénix 1B declares USD 531 M of investment and USD 251 M of computable assets, that is, half. The other three rows are in total investment, so this one is too: counting it with the computable figure would mix two bases in the same sum. It moves with every Official Gazette resolution and every stage that gets approved.
Engineering and control content of the capex2.8% (core) to 4.0% (full scope)structural
The 2.8% is a hard figure, read in the cost table of Sal de Vida's technical report: USD 25 M of engineering and studies on USD 902 M of capex. The 4.0% is our assumption for the niche's full scope, because fabrication inspection and weld control do not live in the engineering line: they live in the indirect construction costs.
Years of execution~3.5 years (mid-2026 to end-2029)structural
The date is set by an act of State: Hombre Muerto Oeste's resolution puts the minimum investment deadline at December 31, 2029. Past the peak, project engineering falls and the perpetual operating core remains: live as-built, piping and tank integrity, plant turnarounds.
Hourly rate (to translate into employment)USD 35-60/h — a stated assumptionlive data
There is no public price for an engineering hour in Argentina and we say so: we checked the professional councils and none publishes it. The band comes from two cross-checks of our own: the loaded labor cost implied by the technical report and the density of hours per dollar of capex. It does not move the TAM in dollars — it moves the hours, and therefore the jobs.
A check on robustness and on fragility. Robustness: the 2.8% ratio is far more reliable than the absolute amounts, because numerator and denominator come from the same table and share a price base. Fragility, stated head-on: Tres Quebradas stage 2 is 63% of the capex still to execute, and since 29 July 2026 it has its resolution published: the risk hanging over this figure is closed. What remains is the base, and it is chosen: the act computes USD 594 million in computable assets and the announcement said 709 of total investment. They are different magnitudes —the computable one is the base of the tax benefit, not the spend on the works— and the basket uses total investment in its four rows.
How solid the number is estim
We opened the anchor for the number ourselves: we downloaded Sal de Vida's technical report —289 pages— and read its capital cost table. Line by line, it says that the engineering and studies cost USD 25 million on a capex of USD 902 million: 2.8% of the works. We applied that real percentage to the Catamarca projects with live construction today, one by one and with the source of each amount —an Official Gazette resolution, the RIGI portal or the Mining Secretariat's official portfolio— and we state which base each figure uses so as not to add apples to oranges. The annual total is our own estimate and we say so. And we also say what we did not find: there is no public price for an engineering hour in Argentina —we looked, including at the professional councils— so the rate we use to translate dollars into jobs is an explicit assumption, not a figure. And on the act that weighs most in the number: the Tres Quebradas stage 2 resolution was published on 29 July 2026 and computes USD 594 million in computable assets verif , a different base from the total investment the basket uses.
