Bulk chemical reagents and inputs for lithium and hard rock, and their last mile to the puna (Salta)
It is the largest of this province's nine markets and the one with the narrowest door relative to its size, and that is worth saying up front: the molecule is not made here. Sodium carbonate travels from Wyoming, from Turkey or from the only producer in South America; one operator's sorbent is patented and another's resin comes from its own supplier. A Salta entrant manufactures none of that. But there is one number that turns the easy conclusion around: between 34 and 45% of the price of that reagent delivered at four thousand metres is not molecule — it is freight, storage and conditioning. There you can get in, and there is a geographic feature Salta has and Catamarca does not: half the lithium plants are not in the puna but on the lowland, connected to a highway and to rail, so they do not need a high-altitude last mile but they do need storage. And on top of that the basket has one local exception, which is the slowest step on the map and the one with the longest horizon.
The number is the reagent delivered to plant, not the operator's chemical spend: it includes the molecule plus everything it costs to get it to four thousand metres. It is built from three blocks, and the distinction that matters is not about product but about who can keep it: two are molecule travelling from outside the country, and one is the service around it.
No rule creates this niche's demand —it is created by the lithium coming out of the plants— and there is one that simply does not apply in the way it is usually cited. The three below define who can charge and how much they keep. The ones below open in the reforms panel on the home page, with their status and primary source.
touchesSalta: 70/60 local mining procurementHere something has to be said that rules out an entire sales argument, and it is worth knowing before investing in the filing: the local content commitments in the resolutions are over the investment amount, and the reagent is operating expenditure — a reagent supply or freight contract does not count within that percentage. The provincial act, for its part, sets a preference of 70% of the annual amount but says shall preferably contract and has no penalty clause. Both improve the buyer's mood; neither guarantees a peso of demand in this category. The real driver of Salta local content is a different one: the reward that allows works to be offset against up to half the quarterly royalty.see the reform →enablesSalta cuts the rate 20% for retail and hospitality, and exempts newly registered taxpayers for 12 monthsIt is the one that funds year one and it has a date: a new taxpayer that registers voluntarily pays a zero rate for up to twelve months, and it lapses at the end of 2026 unless extended. In this niche it matters for a specific reason: the business can be classified under more than one line of the schedule —mining support services, transport of hazardous substances, warehousing— with very different rates and with no permanent exemption in the most expensive one. Whoever invoices everything together without separating the classification loses several points of gross billing in an intermediation business, where the margin is thin by definition.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 does not create reagent demand, but it orders the area Salta shares with Catamarca, and that is where the brine field of one of the projects in the number sits. For this niche the effect is one of perimeter: which side the operation ends up on defines which suppliers' roll the operator buys from, and in an intermediation business that is exactly the difference between being in and being out. Watch clause nine: the agreement lapses when Congress settles the boundary between the two provinces.see the reform →This market does not float on its own: concrete megaprojects drive it.

Watch out for the 1st edition of the same study: it said ALPAT 'has been forced to halt its production' and version 2 corrects that verbatim - do not cite v1 for the company's status.
Between 2016 and 2020 lithium mining alone imported 337,901 t = 34% of all Argentine imports of the compound; annual average 67,580 t = USD 20,178,409, over average output of 32,470 t LCE; average CIF USD 298/t verif primary source opened by me, pp. 23-24 — this is the vintage anchoring the whole model on this page, and it is stated because there is another one: a 2023 CIF of ~USD 485/t [inherited from the Catamarca pass, not opened here], which is not used so as not to mix vintages with the customs series. A 9% non-refundable import duty [inherited]. Not one trader is identified by name either in the official study or in the dossiers: it is the identity hole in the competitive map and it is declared.
A 600 t/day Maerz kiln ≈ 219,000 t/y estim 600 t/day × 365: it assumes 100% availability and is therefore a ceiling, not effective capacity. National lime capacity is 2.38 Mt/y CONCENTRATED IN SAN JUAN and lithium would take 43% of it in the high scenario; its regional director stated that the lithium market asked for ~250,000 t in 2023 and projects +800,000 t for 2027 prob via our survey of the sector. The sentence that defines the niche was said by the businessman who put up the money: the 'logistics costs, which are even more onerous than the product itself' verif Editorial RN - today the operations of Salta, Jujuy and Catamarca bring lime from San Juan.
The 'Silvana Daisy' quarry at cerro Rincón (Pastos Grandes area) with an approved environmental impact study + a calcination plant at Olacapato / San Antonio de los Cobres (Los Andes department; sources differ on the exact locality). First stage 6,000 t/month of calcium oxide = 72,000 t/year. Investment ~USD 10 M, mixed prob two sector sources via our survey. It is not a thesis: it is a Salta businessman putting up money against 1,500 km of freight. And it brings the technical fact almost nobody has: the local Yacoraite deposit is UNSUITABLE because of its high magnesium content (it works for construction, not for processing lithium), which is why specific limestone had to be sought at cerro Rincón.
The logistics fact that opens the niche: on 3-Jul-2026 Transclor dispatched the first rail convoy of HCl to the north, from the Grupo Bueras station (Pilar, Buenos Aires) to the GENERAL GÜEMES logistics hub via Belgrano Cargas, with Grupo Euroamérica, Trenes Argentinos (Operations, Freight and Infrastructure), Hazmat Argentina and Simalo. It was presented as the start of a recurring logistics model, not a one-off operation. Volume and mining client NOT disclosed prob via our survey.
Each one buys through a channel of its own and none decides in Salta —the detail operator by operator is in the global procurement killer—; Eramet does not even buy its separation medium: it uses its own patented aluminate sorbent at Centenario. The reagent can reach the Salta salt flat without a single Argentine purchasing decision existing. It is the structural killer, not a future threat.
Covered shed, silo, big bag yard, weighbridge and forklifts: the same infrastructure four times over across 300 km of puna. The operator does not buy conditioning, it buys reagent delivered to its shed. It is the specific captive to break, and it breaks on price at the next scale-up (Sal de Oro II, expanded Rincón), not through regulation.
A Salta bonded warehouse where Eramine consolidated 100 big bags into MSC containers [inherited from the Catamarca twin, which labels it 'the hub model Catamarca does not have']. For inbound reagent it is the natural dispatch and storage platform: in Salta the gap is not creating the bonded warehouse but selling the integrated BACKHAUL - the truck that takes reagent up and brings product down -, which today nobody declares offering.
Cooperativa De La Puna is the best documented player: Salta's first mining transport and integrated logistics cooperative, 17 members, a fleet of 180 vehicles (freight trucks, specialized machinery, buses, minibuses and 4x4s), based in San Antonio de los Cobres, launched on 8-Sep-2025 verif official note from the Province. It is the only layer with real competition. A negative finding that counts as a gap: none of these carriers declares a dangerous goods transport license in the public sources opened, and HCl, caustic soda and cyanide require one.
It is the infrastructure Transclor has just opened up for bulk chemicals, and together with RN 51 the only real outlet for activity in Rosario de Lerma and Los Andes; it crosses into Chile at Socompa towards Mejillones/Antofagasta. No rail tariff in USD/t is published - a declared gap.
The molecule segment is closed today: it is not made in the country, the operator buys it in bloc from head office and in-plant conditioning is already built. With one exception that is made here, and it is step 6: lime. If producing chemicals is your capability, that is your segment, together with step 4 — bagging and quality control, paid by specification and not by molecule. The rest is the 34 to 45% of the price that is not chemistry, and it is worth entering in this order:
Subcontracted handling and last mile for a carrier already homologated — two to four months to the first invoice and with no homologation of your own. It is the fastest door in the niche and the one that teaches you the real circuit of the cargo: who unloads, where it is stored, how moisture is controlled and what happens when the truck arrives and the silo is full.
Be the first Salta carrier with a dangerous goods license — the niche's only first-mover gap, and the one with the least capital. Hydrochloric acid arrives by rail at General Güemes —the 3 July 2026 convoy proved it— and goes up from there by truck; hydrochloric acid, caustic soda and cyanide all require a hazmat license, and we did not identify a single Salta carrier that declares one in public sources. It is a barrier of paperwork and fleet, not of capital: whoever has it first quotes alone, and the negative finding is precisely what makes it a window and not a race.
Your own storage terminal at General Güemes — the move that defines the business, and it is where Salta's geographic split sits. Two of the four plants are in that industrial park, on a national highway and with rail, and the rail node has just been opened: bulk can come down by train that far. It is what turns freight into an availability contract, which is charged even when the truck does not leave.
Bagging, conditioning and quality control — the margin step, and the one that needs least capital relative to what it leaves. The plants' reagent stores are sized for seven days of cover, so whoever holds conditioned stock nearby sells availability, not product.
Clearance and bonded warehousing on the imported goods — a regulatory barrier and not a capital one. Almost the whole basket enters the country from abroad, and the nationalization fee is a line that today has no Salta player.
Lime, which is the only molecule in the basket that can be manufactured here — the underlying bet and the one with the longest horizon. There is a lime plant being built in the corridor with an approved environmental study and a modest declared investment, sized explicitly to supply three provinces: that proves the return works. And the demand is written into an act of State, not inferred: the resolution approving the second stage of the lithium project says it processes «with calcium oxide or quicklime (CaO)», verbatim. Now the question that matters, because that lime plant is already being built: what is left for whoever comes next. The answer is not to copy it — it is what today each plant does for itself and nobody sells them: on-site slaking and hydration, granulation to specification and the availability contract. It has no public price delivered to the puna, so it could not be quantified; it is the only line where someone from Salta stops being an intermediary.
~USD 60-63 M/year (~85-90% of the TAM #1 midpoint, which is ~USD 70 M/year), in three layers that do not fight each other: (a) THE molecule - it travels from Wyoming, from Turkey or from San Antonio Oeste; ALPAT is the only producer in South America and the US holds the bulk of the world's trona reserves. A Salta entrant does NOT manufacture soda ash, or Eramet's patented aluminate sorbent, or Sunresin's resin. (b) the operator's global procurement, which is the niche's killer number one: when the framework contract is signed by head office, the reagent can reach the Salta puna without an Argentine purchasing decision existing. (c) in-plant conditioning, already built - shed, silo, big bag yard and forklifts, the same infrastructure four times over. The operator does not buy conditioning: it buys reagent delivered to its shed.
USD 3.5-13 M/year addressable by a local or national entrant, and the number is rebuilt in full from its two components: the whole of TAM #2 (storage, conditioning, bagging, quality control and last mile: USD 3-11 M/year) + the clearance and bonded warehouse fee on the imported goods once nationalized, of the order of USD 0.5-2 M/year [assumed]. That gives 3+0.5=3.5 as a floor and 11+2=13 as a ceiling, with no remainder.Regional lime is left out of the number, and it is deliberate. It is the only capturable molecule in the basket -physically 20,000-36,000 t/y in Salta [assumed], and the Nioi lime plant (72,000 t/y for USD 10 M) proves the return works-, but there is NO public price for lime delivered to the Salta puna, so it has no dollar figure. Adding it without a price would be enlarging the market with an invented number, which is exactly what this method does not do. Lime is unquantified upside, not part of the floor — and that is why the addressable bar may sit below what the province could actually manufacture.BEWARE THE 70% AND THE 21.02%, and it has to be said twice: Act 8164 sets a preference -section 17, 'shall preferably contract', WITH no penalty clause- of 70% of the annual amount, and section 20 lowers it to a 40-70% range depending on stage and size, negotiated when the environmental impact study is approved. The 21.02% of Sal de Oro II is a commitment over the investment amount (capex) and the reagent is OPEX: a reagent supply or freight contract does NOT count within that percentage. Both improve the mood and the buyer's disposition; neither guarantees a peso of demand in this category. The real driver of Salta local content is a different one: the reward in section 19 + Chapter II, which allows infrastructure works to be offset against up to 50% of the quarterly royalty.
USD 1.5-4 M/year for ONE entrant over 2-3 years, equivalent to 12-30 jobs estim. Honest arithmetic: you do not win all four operators (Rio Tinto contracts in bloc, POSCO and Ganfeng bring their own chain, Eramet manufactures its sorbent), so the wedge is 1-2 clients over 30-50% of the SAM. Realistic sequence, in this order: (1) subcontracted handling and last mile for a Salta carrier already homologated - 2-4 months to first invoice; (2) your own storage terminal at General Güemes with a contract from one operator - 6-12 months; (3) scaling up to supply delivered to the plant gate by buying the molecule from an importer - 12-18 months.
When you get paid, and what blocks it
effect
It is the niche that creates the least employment per dollar billed and the one that creates the MOST STABLE employment in the whole chain. Both things are true and both have to be said. 70-80% of TAM #1 is imported molecule, not work. But it is opex of operations with 25-40 year mine lives: a reagent driver or a terminal operator does not lose their job when construction ends; the camp erector does. And in 2026 that matters especially, because Salta mining employment fell 5.7% y/y as of March 2026 — the only one of the seven large mining provinces that fell, while the country added 1.2% and the lithium segment 6.5%; the report itself warns that segments were reclassified, so the year-on-year comparison does not run against an identical series verif monthly report of the Secretariat of Mining— while the province sustains 5,730 direct mining jobs (Apr-2025, 14.8% of the country, 2nd nationally behind Santa Cruz).Trades and professions with a concrete route, both bands: dangerous goods driver (hazmat/ADR) - the niche's technical bottleneck, a short certification, no degree, and today almost nobody in Salta declares it: it is the best training-to-income ratio in the segment; forklift and telehandler operator, yard and big bag bagging operative, weighbridge operator and tool-crib storekeeper - the staffing of a storage terminal, with weeks of training; reagent quality technician (moisture, insolubles, batch traceability), the trade born of the purity requirement and which pays a premium; lime calcination, milling and granulation operative - and this is the most important one, because it is industrial employment in the salt flat's own town and not in the capital: the Nioi plant is at Olacapato / San Antonio de los Cobres, Los Andes department. It is the only link in this niche that can become Salta industry and not just a service; fleet mechanic and technical wash bay associated with the hazmat certification; and customs broker or foreign trade assistant, the degree band, along the Güemes-Socompa corridor and the bonded warehouse.The fabric that receives it already exists and is identified: CAPROSEMITP, the Puna chamber based in San Antonio de los Cobres with ~70 active members from Estación Salar de Pocitos, Olacapato, Tolar Grande, Santa Rosa de los Pastos Grandes and San Antonio de los Cobres; Cooperativa De La Puna (17 members, 180 vehicles, launched on 8-Sep-2025 as Salta's first mining transport and integrated logistics cooperative); CAPEMISA in the capital; and the RPPLEM roll with 498 approved suppliers.LINKAGE: regional quarry lime is the only link that turns into industry with stable rather than rotating employment; the bonded warehouse and consolidation turn freight into a foreign trade service, more skilled and better paid; and the storage terminal is infrastructure that does NOT get dismantled when a construction project ends - it serves the next plant.What is not resolved, said head-on: the big part of the money leaves the province and the country and there is no way to dress that up - of the USD 55-118 M/year, between 70% and 80% is molecule bought in Wyoming, Turkey or Río Negro; the honest B-side is the freight, the storage, the customs paperwork and the lime, of the order of USD 3-11 M/year of services plus the substitutable lime, and they are dozens of jobs, not hundreds. Four more things remain open: (1) 55% of the headline rests on an intensity assumption not verified for the LiOH and LiCl routes - the number anchored without assumptions is USD 24-49 M/year, not 90; (2) DLE, which is Salta's technological pride, is the structural killer of this niche's volume: the better the province does on technology, the less reagent it buys; (3) the fiscal asymmetry punishes precisely this link, 3.60% turnover tax on the service against 0.75% -or 0%- on extraction, that is, the provincial State taxes whoever adds local value more than whoever takes the resource out, and that is not interpretation: it is in the schedule; (4) it is employment with real physical risk and no rule - acid and cyanide are transported over gravel at 4,000 m above sea level in a country where there is no legislation setting fitness criteria for working above 3,500 m, so whoever enters this niche is hiring people for a place where the State has not yet set the safety rule.
calculate it
Concentration Extreme in the molecule, thin in the freight, and with local substitution already under way in a single line. It is not a market with a contested share: it is a chain split into three layers that barely compete with one another. Molecule layer: total and mostly foreign concentration - a single national soda ash producer (ALPAT, 225,000 t/y installed, the only one in South America) at ~1,700 km, a dominant lime producer (Calidra) at 1,500 km concentrated in San Juan, and 34% of all Argentine imports of the compound absorbed by lithium mining. The UIA+CAEM+BID report of May 2026 closes it: local supply in 73 of 91 mining categories and SODA ASH among the 18 WITH no local supply. Purchasing layer: the four operators integrate their own global chain (Rio Tinto in bloc, POSCO with Koreans, Ganfeng with Chinese suppliers, Eramet manufacturing its patented sorbent), so the reagent can reach the puna without an Argentine purchasing decision. Service layer: here there is competition and entry - fragmented freight from Salta SMEs (Cooperativa De La Puna with 180 vehicles is the largest player identified) and conditioning redundantly self-provided by the four operators. The operational conclusion: the competition is not where the money is. And there is a structural difference from the Catamarca twin worth not losing: Salta has the downhaul node built (General Güemes Industrial Park with +50 companies and 140 ha being added, with the POSCO and Ganfeng plants inside), it has a bulk chemicals railway opened in July 2026 and it has a bonded warehouse (COCEL). Catamarca has none of the three.
There are four doors, and the first thing to accept is that the biggest one is untouchable: the molecule is bought outside the province and often outside Argentina.
The first invoice, in two to four months, and without passing the mine's register. It is also where the niche's geographic split sits: two of the province's four lithium plants are in the General Güemes Industrial Park, on a national highway and with rail, and those need storage but not a high-altitude last mile. The provincial mining suppliers' roll has 498 registrants with an approved filing, so the intermediate buyer is identified.
The contract that changes the business, because it is charged even when the truck does not leave. The sales argument is operational and it is measured: the plants' reagent and consumable stores are sized for seven days of cover, and at four thousand metres with a gravel road seven days is not much. You are not selling product: you are selling the plant not stopping.
Almost the whole basket enters from outside the country, so there is a nationalization fee on every tonne that today has no Salta player. The barrier is regulatory and not capital. It is worth knowing that the provincial tax bites differently depending on how the activity is classified: mining support services is the expensive line and has no exemption available, while transport of hazardous substances has its own, cheaper code.
The only door where someone from Salta stops being an intermediary and becomes a producer, and that is why it has the longest horizon and the most risk. There is a lime plant being built in the corridor with an approved environmental study, sized explicitly to supply Salta and the two neighbouring provinces: that proves the return works. And the demand is not an inference of ours: it is written into an act of State. The resolution approving the second stage of the General Güemes lithium project under the large investment regime says, verbatim, that it processes «with calcium oxide or quicklime (CaO)» verif Res. 1157/2026, in this page's source list. What still cannot be measured is the size: there is no public price for lime delivered to the Salta puna, so the door goes in as a reading and not as a sized market.
It is not 'what breaks it': it is the dashboard for knowing how much reagent will be needed before it is bought. In this niche the volume is not decided by a construction project or a tender — it is decided by how much lithium each plant produces, which is published quarter by quarter.
It is the only real driver of the niche: every tonne of lithium drags its reagent ratio behind it, and that ratio is verified in an official study —1.4 theoretical and 2.081 real tonnes of sodium carbonate per tonne—. Whoever reads the quarterly production guidance knows the input tonnage before the buyer issues the order. And there is a rule that has to be applied before adding anything: hydroxide, chloride and carbonate capacities are not added together — they have to be converted to a common unit first, or the market comes out inflated without anyone noticing the error.
Quarterly production reports from the operators and the national Secretariat of Mining study on sodium carbonate, plus the annual guidance the issuers publish ↗Three companion signals. The lime plant in the corridor: when it starts up, lime stops being imported from another province and a freight run of almost two thousand kilometres shrinks to forty — it is at once this niche's biggest opportunity and the heaviest blow to the logistics one, so it is worth watching from both sides. The start-up of the plants that are not yet producing: there is approved capacity that is not in the number because there is no public evidence that it is operating, and every one that fires up adds its whole basket. And the exchange rate and the import duty, which in a business where 55 to 66% of the price is imported molecule move the intermediary's margin more than any negotiation with the client.
If the reagent comes in under the operator's trader's global contract, the last mile stays inside that contract and the Salta entrant never sees it. It is not a future threat: Rio Tinto buys in bloc for its brine portfolio, POSCO brings in Korean suppliers, Ganfeng executes with a Chinese chain and Eramet outright manufactures its separation medium (a patented aluminate sorbent). Permanent exposure; it is decided at every renewal of the supply contract.
The Salta precedent is harsh and it is measured: the Rincón Lithium plant (Argosy/Puna Mining, 2,000 t/y) was listed as suspended as of the Aug-2026 cutoff, against the backdrop of a roughly 80% fall in the price prob own survey of the province's plants; there is no operator statement or administrative act backing it, and the chairman of CAPEMISA stated in May-2025 that its member companies had gone from +10,000 employees to 5,000-6,000 in a year and a half prob statement by the chairman of CAPEMISA, operating at ~40% of capacity, with lithium at ~USD 9,000/t prob ídem. Salta mining employment fell 5.7% y/y as of March 2026, to 5,569 jobs verif monthly report of the Secretariat of Mining — the only one of the seven large mining provinces that fell, while the country added 1.2% and the lithium segment 6.5%. But the reagent of a plant that is ALREADY operating is consumed all the same: a price reversal freezes Sal de Oro II, the expanded Rincón and Pozuelos-Pastos Grandes -that is, the growth-, not the 2026 base.
For TACA TACA there is no public evidence that it has filed its application to the large-investment incentive regime —the title holder stated in Feb-2026 that it was preparing to file, and the official portal does not publish the detail of the projects under review, so non-filing cannot be verified there unconf status of the filing—, and its environmental impact assessment was still unapproved as of Q2-2026 (FQM statement): it is the ceiling of the hard rock niche and today it is worth zero. DIABLILLOS has its Environmental Impact Statement (Res. 048/2026) and RIGI (Res. 562/2026) but lacks financing -target Q4-2026- and FID -Q2-2027-: its USD 15-19 M/year of reagent depend on a capital markets decision, not on the State. POZUELOS-PASTOS grandes is a step further down in firmness: application filed on 28-Feb-2026 and unresolved, ~USD 3,000 M. None of the three is in the TAM.
The Salta perimeter is mostly DLE (Rincón, Centenario -the first plant to take Eramet's DLE to industrial scale-, Pozuelos-Pastos Grandes and Arizaro), and that plays AGAINST this niche: less evaporation and less softening push consumption from the 2.081 t/t actually observed towards the 1.4 stoichiometric figure, that is up to 33% less soda ash for the same output. Both ratios are verified in the same official primary source that anchors the TAM. It is the silent killer of volume: the better the province does on technology, the smaller the cubic metre of reagent it buys.
It is what sets this niche apart from camps, geomembranes or earthworks within the same batch. The reagent is PERPETUAL OPEX, not construction capex: Rincón declares a 40-year mine life and Diablillos 25 years at 9,000 tpd verif. There is no post-2029 cliff; there is an operating core that grows with every ramp-up (Sal de Oro II 23,000 t/y, expanded Rincón 53,000 t/y). This niche's risk is not that construction ends: it is technological substitution and the integration of the operator's chain.
Mining support services (code 99000) pay 3.60% turnover tax with no permanent exemption, against 0.75% for extraction and 0% with an exemption certificate verif the activity schedule of Salta's Revenue Office. It is 4.8 times the mine's rate. In a freight and handling business with a 12-20% net margin there is no cost of goods to dilute a tax on gross billing: 3.60% eats of the order of a fifth of the result estim. And there is a structuring decision almost nobody sees: selling the reagent (wholesale trade) and PROVIDING the service (code 99000) are taxed differently, and the service pays LESS. Wholesale trade in chemicals pays 5.00% verif the activity schedule of Salta's Revenue Office, code 466932 'wholesale of intermediate products, waste and scrap of rubber, gum and chemicals n.e.c.' and 466931 'fertilisers and pesticides', both on p. 31 of Annex I; the same rate applies to 466200 'metals and metal ores' (p. 30) and 469090 'goods n.e.c.' (p. 31). That is 1.4 points in favour of billing the service rather than the resale - the same direction the business already pushes: here the margin is in storage and the last mile, not in the molecule.
The Salta precedent is recent and it comes with a figure: in Jul-2026 Salta's Civil and Commercial Court No. 2 ordered the attachment and freezing of POSCO Argentina's accounts over claims by Salta contractors tied to project works —a pumping station and the aqueduct—, for an amount sources put at between USD 357,763.20 and «in the millions» prob sector press; there is no published court ruling. POSCO acknowledged the dispute, maintains that there is no final ruling, and contested the claim publicly. And the chairman of CAPEMISA stated that 'the local content percentages are not met in full'. Added to the fact that there is NO public data on the mining companies' payment terms in Salta, working capital risk is the real one, not capex.
The San Antonio de los Cobres -> Paso de Sico stretch is still gravel; paving it would cut transport cost by ~40% according to CAPEMISA unconf it is an interested party lobbying for paving. Salta took a FONPLATA loan of USD 100 M over 20 years, with 5.5 of grace and SOFR + 233 bp, whose use the act earmarks BY CATEGORY —road infrastructure, water and sanitation, and technology for border-control posts along the Capricorn Bioceanic Corridor— and not by works: it does not name this stretch verif full text of Act 8506 opened in Official Gazette 22047. WATCH THE AMBIVALENCE, which almost nobody points out: the gravel surcharge is ~40% of the freight price, so paving enlarges the lithium market and shrinks the last mile freight margin. A supplier in this niche should not assume public works play in its favour.
If it executes the expansion it declared to the State (300,000 t/y and then 500,000 t/y verif prose on p. 13 of the official study), the national price falls and the trading margin compresses. Take care not to confuse that expansion with the nameplate capacity series in the table on that same page — 250,000 → 330,000 → 550,000 verif ídem —: they are two different objects in the same document. If import pressure beats it, 100% is imported with a 9% duty. Neither scenario touches the last mile: the ~1,700 km to the salt flat are still there, and the official study itself wrote that over that distance 'the installation of a complementary plant in the area of the lithium projects should be considered'. It is the indicator that says WHICH business to build, not whether to build it.
Tonnes of lithium produced times reagent intensity times the price delivered to plant, with a cross-check by the physical route that shares with the main calculation the lithium tonnage both start from: it serves as order of magnitude, not as independent verification. One discipline orders the whole exercise: lithium capacities are not added together — carbonate, hydroxide and chloride are different products and they have to be converted before being summed.
A robustness check along three paths, and the honest result is that one confirms the direction but not the level, another bites and exposes an assumption inside the method itself, and the third does not discriminate and is declared as such. (a) The twin on the other side of the salt flat, normalised per tonne of lithium. Catamarca publishes the same business —lithium reagents delivered at plant gate— at USD 55-95 M/year, midpoint ~70, over 40 to 50 thousand tonnes of effective carbonate. Here the midpoint is the same figure, ~USD 70 M/year, over 42,215-53,544 t LCE-eq. Two provinces publishing 70 proves nothing on its own; what can be measured is the implied figure per tonne of lithium, and there they do separate: once the ~USD 6 M of stockpiling and last mile that this TAM contains and the other one counts separately are removed, Salta implies USD 1,337 per tonne LCE against USD 1,556 in Catamarca, that is 14% cheaper. That is exactly the direction the process route anticipates: Catamarca is carbonate by evaporation, where measured real soda ash consumption is 2.081 t/t; Salta is mostly direct extraction and hydroxide, where that consumption falls towards the theoretical 1.4. But it is not an independent verification and that has to be said: both calculations use the same price band —the USD 1,314/t floor from the Sal de Vida NI 43-101 and the official USD 1,918/t midpoint— and hang from the same primary source. What it does prove is that the two halves of the triangle rank the way the chemistry dictates; what it cannot prove is the level, because the level is the same input in both. (b) Top-down from foreign trade, which is the only OBSERVED value in the whole chain. Everything else on this page is capacity, ratio or reference price; imports are a series measured at customs. The official study publishes the three figures needed: lithium mining imported 67,580 t/year of sodium carbonate for USD 20,178,409 while the country produced 32,470 t LCE (2016-2020 average). That those three reproduce exactly that same ratio and the USD 298/t CIF stated in the same table is the proof they have been read correctly. Divided the only way that matters here: USD 621 of CIF soda ash per tonne LCE, or USD 1,021-1,240 delivered at plant using the same 1.6-2.0× CIF→plant step this calculation builds link by link. Both figures come from the same CIF vintage —the 2016-2020 one— and that is why they can be divided: it is the series this path measures at customs and the one anchoring Step 3. Against the official midpoint for total reagents —USD 1,918/t LCE, measured at those same evaporation plants—, soda ash accounts for 53-65% of reagent spend, not the 85-90% the physical cross-check assumes. The headline does not depend on that assumption —it is built as base × price— but the physical cross-check does: if soda ash accounts for two thirds of reagent spend rather than 85-90%, the same tonnage implies around 50% more —a factor of 1.5— the carbonate-route reagent that cross-check states, and pushes it above the band it publishes itself. This is deliberately left in percentage terms and not in dollars: the floor of that leg is one of the figures the TAM's own audit flagged for recalculation. The reading is that if the figure is off, it is off downwards. (c) Weight within the province: here it does not discriminate, and the reason is arithmetic. This is the path that worked for metrology. Added together, Salta's nine investor markets come to USD 229.3 M/year and this one weighs 30.5%; in Catamarca its twin weighs 41.7% of 167.9. The gap looks large and tells us nothing, because both numerators are the same figure: the eleven points of difference are entirely the Salta denominator, which is 37% larger. The control confirms the method does discriminate when numerators differ —the brine laboratory weighs 1.7% in both provinces and high-altitude health 2.5% against 3.5%— but here they do not differ, so it is declared and not used to move the figure. What still stands: the level rests on the method —physical base converted with an explicit factor, times a three-anchor price band— and not on these paths. Path (a) proves that Salta and Catamarca rank the way the chemistry dictates; path (b) is the only one that bites, and what it bites is not the headline but an assumption in the cross-check, in the direction that the published midpoint is conservative; path (c) does not apply. The gap remains the one the TAM itself declares: without a reagent consumption ratio for direct extraction, 100% of this market rests on a process-route assumption.
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 number was built by two paths that share the physical base and part company only on price, and their agreement is published for what it is worth: an order-of-magnitude check, not an independent validation. The first starts from the price per unit of lithium: reagents are 40.9% of production cost for the country's brine projects according to an official study by the national Secretariat of Mining, opened with our own eyes. The second starts from the physical route: how many tonnes of sodium carbonate each tonne of lithium consumes —1.4 theoretical and 2.081 as the real average between 2016 and 2020, both read in that same study's table— times the price built link by link, which is what separates the value at port from the value delivered to plant: import cost, duty, trunk freight, last mile and storage. Both paths give the same band, and it is worth saying why that proves less than it appears: they start from the same lithium tonnage —the only thing independent between them is the price—, they value at different vintages, and the weight that turns tonnes into dollars —what fraction of the carbonate route's reagent is soda ash— is our own assumption: moved downwards, the agreement disappears. From there comes the finding that orders the niche: the reagent delivered at four thousand metres costs between 1.4 and 1.6 times its value at port. The physical base respects a rule almost nobody applies: lithium capacities are not added together. Hydroxide, chloride and carbonate are different products, so each plant was converted to a common unit with its stated stoichiometric factor before anything was added. Three things are declared and bound it. The utilization of one of the plants has no public figure and goes in as our own assumption. The block covering the hydroxide and chloride routes assumes the same reagent intensity per unit of lithium as the carbonate route, and that is not verified for those two routes — with 30% less, the midpoint falls appreciably. And there is a tension left in plain sight: the declared national consumption of sodium carbonate by Argentine lithium is lower than what Salta alone would consume at this scale, because the national figure is from a period before the Salta start-up. The conflict is declared instead of picking the comfortable number. And what was left out: the silver project is not operating yet, so its reagents go declared and not added; and milling consumables are steel, not chemistry.
