High-altitude occupational health: fitness, medical surveillance and medical transfer in the Salta puna
It is a small market next to the big ones in the chain and the one with the sharpest gap, because here the law neither helps nor hinders: it simply does not exist. There is no Argentine legislation setting medical fitness criteria for working above three thousand five hundred metres — no compulsory examinations, no frequencies, no thresholds. And yet every site buys the examination anyway, because it is required by the operator's corporate standard, its insurer or its international lender. That leaves a market with an odd shape: both ends are already taken —the largest operator resolves fitness with its own medical team, and air evacuation is contracted through corporate procurement that may never pass through Salta— and nobody sells the middle. And there is a difference from almost all the other niches worth understanding before investing: a medical consultation cannot be imported. The examination is done where the person is and the ambulance has to be on the road.
The number is contractable medical fees: the examination that clears you to go up, the check that repeats and the operation that brings somebody down when something happens. It does not include the medical service the operator has in-house or workers' compensation insurance. It is built from three blocks with three clients, three tickets and three different barriers — and only the middle one is genuinely open.
The feature that defines this niche is an absence: there is no altitude rule, and that is why the list below does not include the one that would create the demand. The three that do apply define who can charge for the service and how much they keep. The ones below open in the reforms panel on the home page, with their status and primary source.
enablesSalta: 70/60 local mining procurementIt defines who counts as a local supplier and opens the door to the outsider with the joint venture from 30%, which in this segment is the natural way to partner with a national medical network without moving the company. But it is worth reading it in full before building a plan on top: it sets a preference of 70% of the amount and 60% of the payroll, the section says shall preferably contract and the act has no penalty clause. The one that does have teeth is the one tying a progressive regime to the approval of the environmental and social impact study.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 a niche where an entrant's wedge is hundreds of thousands of dollars a year and not millions, twelve months with no tax rate is a large part of the start-up capital — more than in any of the other eight, precisely because it is the smallest market.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 medical demand, but it directly affects the count of exposed people, which is the driver of the number: it orders the area Salta shares with Catamarca, where a source places a site whose industrial complex is instead at 800 metres — and at 800 metres there is no altitude medicine. That ambiguity is why this block was sized with a wide band instead of picking the number that enlarges. Watch clause nine: the agreement lapses when Congress settles the boundary.see the reform →This market does not float on its own: concrete megaprojects drive it.

split
The real owner of this market is not a supplier: it is the operator that brings it in-house. The setup measured at a single camp is 4 permanent doctors prob interview with the project's medical coordinator, 2023, 2 equipped emergency rooms prob same source, 3 ambulances prob same source, 1 light vehicle with paramedics and 1 rescue vehicle with firefighting staff prob same source and a weather-limited medical airstrip prob same source. It has its own medical coordination, with a published name prob same source. The most important fact in this entry: that camp has a kitchen and canteen sized for more than 2,000 people per day verif the contractor's own project sheet opened on 2026-08-05, and from there a headcount of the same order is read prob the sheet does not declare beds, that is between 40 and 55% of all the exposed people in the province estim our own calculation, and its fitness and its surveillance are done by its own team. A caveat so as not to exaggerate: the source is single and three years old; it is used as the shape of the package, never as a provincial average.
It is the counterexample to the claim that the capacity does not exist: it exists, it is from Salta and it is in the mining suppliers' chamber under the category Occupational Medicine, Laboratory and Diagnostic Imaging verif chamber entry opened on 03-08-2026. Founded in 2008 verif same entry and it declares more than 70 specialists verif same entry. It has a specific altitude medicine area, pre-employment and periodic examinations, psychometric tests, absenteeism control, telemedicine and a 4x4 advanced life support ambulance described as ideal for emergencies in remote and hard-to-reach areas such as the Puna, plus an acclimatization programme verif its own site opened on 03-08-2026. What it does not publish, and this is what defines the gap: no prices, no named mining clients, no altitudes, and no contract with a committed response time. It sells the two ends -the examination and the ambulance-, not the integrated package in the middle.
It declares more than 10 years working in oil and remote areas unconf no primary source opened. Neither its reach in the puna nor a mining contract could be established. It is listed because it is the other local door identified and because omitting it would overstate the gap.
9AMAS appears under the verbatim category emergency training and drill services verif chamber roll opened on 03-08-2026: it is training, not clinical provision. AIROX appears as medical, industrial and laboratory gases verif same roll. They matter because they prove that two links of the chain -training emergency responders and supplying medical oxygen- already have a Salta supplier, and that the one missing is the one in the middle. A methodological caveat: the chamber's roll runs to 16 pages verif same roll and only the first was read plus the health member's entry, so NO claim is made about how many health providers there are in total.
It does not set up its own arrangement: it has a shared-resources agreement with the large neighbouring operator for multiple-casualty incidents prob interview with the medical coordinator, single source. It is the best available proof that the every-man-for-himself model has already cracked and that the buyer has understood that this gets shared. What is missing is not the buyer: it is the supplier who sells it as a service with a committed level instead of as a favour between neighbours.
They pay the claim and channel the compulsory pre-employment examination towards the providers in their own network. They are at once the second wallet behind the retainer and the direct competitor of any entrant wanting to sell the examination on its own. None of them sets up the on-site medical cover or the ambulance in the puna.
The chamber brings together some 70 active members prob local press from Estación Salar de Pocitos, Olacapato, Tolar Grande, Santa Rosa de los Pastos Grandes and San Antonio de los Cobres, and among its named cases there are companies with health services and nutrition consulting categories prob same source. It is a declared category, not established capacity: none publishes clinical scope or a contract. They matter for another reason: they are the local partner with which an outside operator puts together the joint venture that lets it qualify as a local supplier.
A negative finding that is declared instead of omitted: NO named Salta contract was found for any national medical emergency operator or any Chilean site health provider unconf our own search with no result. They have fleets, a dispatch centre and scale; what they lack is altitude and local roots. A concrete latent threat: if an operator unifies procurement at a regional scale, the full package comes in from outside with the learning curve already paid for. If one of them is already inside, the gap is smaller than this analysis says.
It is the de facto safety net for everything the site does not resolve. Declared gap, not filled in: the installed capacity of the San Antonio de los Cobres hospital and of the health posts of the Los Andes department was not established, so no claim is made about their reach. It affects both the sizing of the transfer block and the reading of the niche's social spillover.
The ambulance is not the door: it is the highest ticket, the most closed and the one with a barrier no supplier controls. But it is not out of reach — it is step 5, and what opens it is not a fleet: it is one unit sold to several sites at once, once the monitoring retainer already pays for the structure. If you already own vehicles, the order below is not a list you are left out of: it is the road to your segment. You get in through what repeats and through what nobody has written yet, in this order:
The periodic surveillance and telemedicine retainer — low capital, recurring income and it is the only block where a small company from the province really competes. It is sold per person per month, it requires neither an airstrip nor an ambulance, and it grows on its own as new sites come on line. It is the door and it is what funds the rest.
Write the high-altitude fitness protocol — zero capital and it is the play of the niche. There is no national rule setting criteria, so today each operator applies its imported corporate standard. Turning up with a protocol of your own —what is measured, at what thresholds, how often, how re-assessment after an event is documented— defines the specification the service is later bought against, and along the way builds a track record no competitor can copy quickly.
The fitness examination performed in Salta — the highest-volume block, and its advantage is geographic: the person is here. Today part of it travels or is resolved through the provider network the insurer chooses from its head office, and that decision is not taken at the site. It is won by showing that doing it in the province is faster and cheaper than sending people away.
Emergency responder training and on-site response — the natural complement to the protocol, with the same buyer and the cost of sale already paid. It is training, not equipment, and it is billed per course and per person.
Medium and long-distance ground transfer: one ambulance, several sites — the step that does require assets, and the one before taking on the large operator over emergency. The shape that makes it viable is not a fleet: it is one advanced life support unit with crew on standby —of the order of USD 90,000 to 150,000 per unit per year— plus an evacuation agreement with a committed destination and deadline, sold to several sites at once. The asset is mobile, so you start with a single one. The natural logistics base is San Antonio de los Cobres, the department's main town and the seat of the Puna suppliers' chamber. And the buyer has already shown it buys shared: the resource-sharing agreement between two neighbouring operators that this same page documents is that contract, today handled as a favour between neighbours instead of as a service with a committed level. It is worth doing once the surveillance retainer already pays for the structure, not before.
~USD 2.5-3.5 M/year (45-60% of the midpoint), with four sources of capture: (a) the internal setup of the largest operator, which is the site with the most exposed people in the province and already has its own doctors, its rooms and its ambulances: its fitness and its surveillance are resolved by its own team; (b) the workers' compensation insurer channel, which refers the compulsory pre-employment examination through its own network and not by a decision taken at the site; (c) the operator's own chain -Korean suppliers, a Chinese chain, a European or Australian corporate standard-, which resolves through global procurement what it does not want to argue about locally; (d) air evacuation, contracted through corporate procurement with an international operator and which may never pass through Salta. An honest counterpoint that has to be stated because it changes the result: unlike a reagent or a piece of equipment, a medical consultation cannot be imported. The examination is done where the person is and the ambulance has to be on the road. That is why this niche's captive share is smaller than that of reagents or energy, but larger than that of drilling, because here the largest buyer already has it resolved in-house.
~USD 2-3.5 M/year, midpoint ~USD 2.6 M/year, addressable by a local or national entrant: the high-altitude fitness examination performed IN Salta for the sites that have not internalized it, the surveillance and telemedicine retainer, the advanced life support ambulance with crew on standby, medium and long-distance ground transfer, emergency responder training, and the written and audited fitness protocol. BEWARE THE 70%, THE 60% AND THE 21.02%: the local purchasing preference (70% of the annual amount contracted) and the preferential hiring of local workers (60% of the payroll) enlarge the addressable market and are an auditable sales argument because they are in the text of the act. But the section says -preferably- AND THE ACT HAS NO penalty SECTION: it is a preference, not an obligation. The one that does have teeth is the one tying a progressive system from 40% to 70% to the approval of the environmental and social impact study. And all three are commitments over the investment amount, not over this category: an operator meets them by buying earthworks and transport, which is where the volume is. They are not a quota and they are not guaranteed demand. The same applies to the 21.02% committed by the second stage of Sal de Oro.
USD 0.4-0.9 M/year for ONE entrant over 2 to 3 years, that is between 15 and 45% of the addressable market taken at its low end (0.45 x 2.0 = 0.9), which is the ceiling the SAM itself supports. CORRECTED ON 2026-08-03: the agent declared 0.4-1.2 and its own composition added up to 0.40-1.30 -it did not even tie out against itself-, and the 1.2 required a single entrant to take 46% of the SAM's midpoint. The three legs are recomposed below so that they ADD UP. Realistic, staged composition: (year 1) the protocol plus the examination - a high-altitude fitness centre with its own protocol and a digital health record, sold first to the contractors and to the mid-sized operators, USD 0.15-0.35 M/year with 3 to 6 professionals; it is the lowest-capital door in the whole niche and it does not require being at the site; (year 1-2) the surveillance and telemedicine retainer over 1,000 to 2,500 people covered, USD 0.10-0.25 M/year, which is where the provider becomes recurring and stops depending on the purchase order; (year 2-3) one to three advanced life support ambulances with crew on standby plus the transfer agreement, USD 0.15-0.30 M/year, the step that requires capital, a medical transport licence and clinical waste management. Outside the wedge: the air ambulance, which does not fit into 2 to 3 years. It is a 20 to 45 person company, replicable in Jujuy and Catamarca along the same puna corridor, and it is not a unicorn.
When you get paid, and what blocks it
effect
It is the niche with the shortest ladder of trades in the whole Salta mining wave -because almost everything is certified rather than degreed- and at the same time the one that leaves the least employment per dollar billed. Both things are true and both have to be said together.Employment, counted. The contractable market this calculation measures -fitness, surveillance and transfer- supports of the order of 35 to 70 direct jobs in the province estim: 2 to 3 people per ambulance on standby over 8 to 20 ambulances, plus 6 to 15 professionals and technicians in the fitness centres and the telemedicine control room, plus health record administration. Counting in addition the on-site medical cover -which today is the operator's payroll and therefore goes declared and not added- that is another 60 to 110 jobs estim. And what sets them apart from the rest of the wave: they are operating jobs, not window jobs. They do not switch off when construction ends in 2029.Concrete trades, with a route and no university degree: emergency medical technician -the segment's real entry door-, nurse with a critical care orientation, altitude ambulance driver (professional licence plus driving on gravel, snow and at 4,000 metres), altitude and confined space rescue technician, dispatch and telemedicine control room operator, medical equipment maintenance and calibration technician -a certifiable trade that does not exist in the province today-, occupational health records administrator, and altitude first aid responder: every site needs its own, and that is recurring sales over thousands of people. And from the degree band, which is exactly where the scarcity is greater: occupational physician with training in altitude medicine and hypoxia, respiratory physiotherapist, nursing graduate and health and safety graduate.Training: the gap is named by an international body and still unexecuted. The sector study documents that Salta is the only province in the lithium triangle with an oversupply of professionals, scientists and managers -because its two universities lead on students and graduates- and that its deficit is in health: university nursing, a nursing degree and, in technical diplomas, health again. Translated without euphemism: Salta trains geologists and does not train the nurse for the camp at 3,700 metres. The provincial technical training system has more than 2,300 enrolments and no site in the Puna; the national university runs a technical diploma in San Antonio de los Cobres and its own campus in the department is still awaiting enactment. And the recommendation to create a Puna training centre was written down and left unexecuted.Local linkage, real and bounded. The service buys medical oxygen -and there is already a Salta supplier in that category in the mining suppliers' chamber-, pharmacy and drug supply, medical equipment maintenance and calibration, clinical waste management, medical laundry, a mechanical workshop for the ambulances and fuel. It does NOT buy the diagnostic equipment, which is imported and has no national substitute in sight. The real linkage is in the service and the maintenance, not in manufacturing, and it is better to say it that way than to promise an industry that is not going to exist.The civilian spillover, and here it is one of the clearest in the whole chain. An advanced life support ambulance and a rescue team BASED in the Puna cannot fail to spill over: the same resource that covers the salt flat covers the accident on the national highway, the obstetric emergency in San Antonio de los Cobres and the tourist at Tolar Grande. It is mining infrastructure that reads as a public service with no need for a story around it.What is not resolved, said head-on:(1) the price is not measured, and it is the parameter that governs the number. The calculation's three prices -examination, per person retainer and ambulance-year- are declared assumptions. There is no public tariff for high-altitude occupational health in Salta and the only established provider in the segment does not publish prices. The market can be sized; the business still can NOT be sized, and that is the difference between this document and an investment plan.(2) The transfer rate is a pure assumption: there is no public data on accident rates or turnover in Salta mining, and three search routes were attempted and all three failed. It is the weakest of the three blocks and it is declared as such.(3) The observed standard is from a single camp, a single source and 2023: it was reopened and confirmed verbatim, but it is still a single issuer and three years old. It is used as the shape of the package, never as a provincial average.(4) Qualified medical employment is the least localizable of the whole wave: there is no 80% of Salta altitude health staff, and the local content act requires it to qualify as a local supplier. At the start the doctors will come from the city of Salta, Tucumán or Buenos Aires; what is quickly localizable is emergency technicians, nursing, drivers and rescue technicians. And today nobody is training altitude physicians in the province.(5) The elevation of the second Sal de Oro plant's construction is not resolved and it moves the roll: if all that construction were at altitude, the fitness block would grow by around 25%. It was resolved with a wide band, not by picking the number that enlarges.(6) The regulatory framework is not empty, and selling it that way is selling a finding that can be refuted in the first meeting: the national mining health and safety regulation applies, it is mandatory, it corrects for altitude and it sets a hard oxygen threshold. What is missing is the rule on medical fitness and hypoxia surveillance.(7) The capacity of the puna's public health system was not measured: the San Antonio de los Cobres hospital and the department's health posts are today the de facto provider of last resort, and their installed capacity was not established. It is a gap that affects both the sizing of the transfer block and the reading of the social spillover.
calculate it
Concentration It is not a concentrated market: it is a half-formed market, with demand concentrated and supply split into two ends that do not meet. The entrant who does not see that shape picks the wrong product.On the demand side - high and physical concentration, and largely already resolved in-house. Nine altitude sites spread over two departments, and a single one accounts for between 40 and 55% of all the exposed people in the province. That is what would make a shared retainer viable... and it is exactly what makes the largest client no longer need it, because it built its own setup. The niche's paradox is right there: the ideal buyer is the one least likely to buy.On the supply side - it is not concentration, it is the absence of a middle layer. The two ends are taken: at the bottom, the fitness examination and the ambulance are already sold, and there is an established Salta provider that sells them and that has been in the mining suppliers' chamber for years; at the top, corporate medical direction and the standard that comes down from head office are never outsourced. What nobody sells in Salta is the package in the middle, which is precisely the one that decides whether somebody lives: continuous surveillance with a committed and auditable response time, a written high-altitude fitness protocol, and guaranteed transfer with a destination and a deadline.There is no public register of awards, so any concentration index would be invented. What can be stated with our own numbers is the shape of the market and the order of magnitude of the split.What should not be sold as a gap, said head-on: -there are no altitude health providers in Salta- is FALSE, and it is the same failure mode as saying the province has no laboratories. There is a Salta provider with an altitude medicine area, telemedicine and a 4x4 advanced life support ambulance, a member of the mining suppliers' chamber, with more than seventy specialists and fifteen years of track record. This niche's gap is not one of existence: it is one of integration and of standard.
Here whoever decides is almost never at the mine, and that is the fact that most orders the sale: of the five doors, only one is knocked on at the site.
The only door knocked on at the mine and the best one to start with: recurring income, low capital and no competing against the largest operator's internal medical team. The universe is measurable — 5,730 registered mining jobs as of April 2025, of which only a part work at altitude, because the rest are in the industrial park on the lowland where ordinary occupational medicine is sold. And it is not «the site» in the abstract: the ones that qualify best are those already in operation —not at peak construction— and for which no medical setup of their own appears in any public source: Borax, at Tincalayu (4,100 m) and Sijes (3,870 m), Lindero, Centenario-Ratones and Mariana. Borax, moreover, is not lithium: its cycle does not move with the carbonate price.
The highest-volume door and the one most often lost by not understanding who decides: the compulsory pre-employment examination is referred by the insurer to its own provider network, and that decision is taken outside the site and outside the province. It is not won by convincing the mine manager. The argument that does work is about cost and lead time: the person is already here, and sending them away costs a fare, a lost day and a delayed start.
The highest-margin door and the zero-capital one, and it exists because of a vacuum: there is no Argentine legislation setting medical fitness criteria at high altitude. Today each operator applies the corporate standard it brings from abroad. Whoever writes the local protocol is not selling hours: they are setting the requirement everything else is later tendered against. It is a reading of the context and not an established obligation — which is why it is declared that way.
The highest ticket and the most closed of the four. The site with the most exposed people in the province resolves it with its own resources, and air evacuation is contracted through corporate procurement with an international operator that may never pass through Salta. On top of that there is a barrier no supplier controls: the airstrip the weather closes. You get in through long-distance ground transfer, which is the piece that is outsourced.
The lowest-friction door, and it was not on this map: two of the seven most active employers on Salta's official mining job board are temporary staffing agencies, Randstad and Adecco, and they are the ones employing exactly the exposed roll this market measures. The pre-employment and periodic examinations are owed by the employer, so the agency is the buyer even though the work happens at somebody else's site — and there the client is the supplier, not the mine, so it requires neither qualifying as a local supplier nor passing corporate homologation. Neither of the two is covered by a mining company collective agreement.
It is not 'what breaks it': it is the dashboard for knowing whether the market you are looking at is altitude or lowland. In this niche the expensive mistake is sizing against the province's total mining employment, when a large part of those people work where altitude medicine does not apply.
It is the niche's only hard anchor, because this market is sized by people and not by dollars. But two corrections have to be applied to it that almost nobody makes, and they run in opposite directions. Upwards: the two-crew rosters mean the roll of people is close to double the number up there at any one time, and the examination is billed per person. Downwards: not all Salta mining works at altitude — the part in the industrial park, at 800 metres, buys ordinary occupational medicine, which is a different service at a different tariff. Applying only one of the two corrections gives a badly wrong number in either direction. And the sign has to be stated: that figure comes from a 5.7% year-on-year fall, and Salta was the only one of the seven provinces with the highest mining employment to fall in March 2026 — while Catamarca rose 21.9% and San Juan 8.4%. It is still third in the country behind Santa Cruz and San Juan, but whoever sizes against this market has to reckon with a roll that has shrunk, not expanded.
Salta's General Directorate of Statistics and the national registered employment record by sector, published quarterly ↗Four companion signals, and the first is the only one already signed. The multilateral financier: the province's largest project closed, in March 2026, financing of USD 1,175 M with four international credit institutions, and the performance standards of one of them already operate as a reference on the project's social front. A lender of that kind audits occupational health and safety and asks for documented evidence — and there is the asymmetry that orders the niche: an Argentine rule can take years; a loan condition applies from signing. Then, any national or provincial rule setting fitness criteria for work at high altitude: today there is none, and the day one appears this market stops depending on the corporate standard and becomes compulsory — it is the trigger that would turn a small niche into a mid-sized one overnight. The final investment decision on the silver project, expected in 2027, which adds its peak of exposed people to the roll. And whether the largest operator opens its medical service to third parties: while it keeps it in-house, half the market is not contested.
There is no Argentine rule on medical fitness and hypoxia surveillance for high altitude equivalent to the Chilean one prob it is a statement of absence and not a text. With no legal floor, surveillance is among the first lines cut when costs bite, and the very fact that creates the gap makes the price impossible to fix. A NUANCE THAT HAS TO BE stated so as NOT TO EXAGGERATE: what is discretionary is the scope, not the existence of the service. The national health and safety regulation for mining, with 191 sections verif text of the rule opened, requires an internal or external health and safety service directed by a specialist, mandates correcting contaminant measurements for altitude above sea level, and declares unfit for human presence any site with less than 19% oxygen or its equivalent value by altitude verif same sections. Our own check, done for this entry: the 2026 regulatory output of the national workers' compensation body was swept verif official gazette consulted on 03-08-2026 and the only candidate resolution, of 24-07-2026, turned out to be a clean-up of repealed rules, without a single mention of altitude or mining verif text of the official notice. The vacuum is still live.
This market bills per exposed person, so a roster that shrinks is revenue that disappears with no cushion. Three data points, and all three point the same way: Salta's mining employment fell 5.7% year on year through March 2026, to 5,569 jobs verif monthly report of the Secretaría de Minería —the only one of the seven large mining provinces that fell, while the country added 1.2%; a 2,000 tonne-per-year lithium project was listed as suspended as of the Aug-2026 cutoff prob our own survey of plants in the province; there is no statement from the operator nor an administrative act backing it, against the backdrop of a roughly 80% fall in the price; and the mining suppliers chamber said its members were operating at around 40% of capacity in May 2025, after going from more than 10,000 employees to between 5,000 and 6,000 in a year and a half prob statement by the chamber's president. REAL COUNTERWEIGHT: the hard provincial anchor is still high -5,730 mining jobs in April 2025, 14.8% of the country and second place nationally verif official provincial report-, so the market contracts, it does not disappear.
Taca Taca, with USD 5,250 M announced verif technical report from the title holder, has no public evidence of having 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 projects under evaluation, so non-filing cannot be verified there unconf status of the filing. Diablillos only decides its investment in the second quarter of 2027 prob feasibility study. Pozuelos-Pastos Grandes, at around USD 3,000 M, has been filed since 28-Feb-2026 and still had no published resolution as of the Aug-2026 cutoff prob sector press. None of that is added into this calculation, and anyone who sizes health infrastructure against those projects funds on-call shifts nobody pays for.
The province's largest buyer has already built its own setup: 4 permanent doctors, 2 emergency rooms and 3 ambulances at a single camp prob interview with the medical coordinator, single 2023 source, and it has its own medical coordination prob same source. A life-or-death service is approved through a corporate health and safety audit, not at a business roundtable, and once it is built it does not get dismantled. It is the structural difference from almost every other service market in the province: here the leader is not a client, it is the competitor.
The occupational medical service pays 3.60% turnover tax with no permanent exemption verif activity schedule of the provincial revenue office, whether it is classified as professional, scientific and technical activity or under the generic mining support heading verif same schedule. Meanwhile mining extraction pays 0.75% and as little as 0% with an exemption certificate verif same schedule: 4.8 times the mine's rate. A live uncertainty that has to be declared: medical transfer might be classified as transport at 2.00% verif that the rate exists, not established that it applies here. Annex I does carry the full family of PASSENGER transport at that 2.00% — including the generic 492190 for passengers n.e.c. — verif Annex I p. 35, but none of those entries names medical transfer, which may still fall under human health: what is missing is not the rate, it is the Revenue Office's classification criterion. Everything was quoted at 3.60%, which is the conservative classification; if the transfer were classified at 2.00% that gains 1.6 points of gross revenue on that component estim own calculation: the subtraction between the two rates.
The legal investment deadlines expire on 30-06-2029 and 31-07-2029 depending on the project verif resolutions published in the official gazette. But this niche has a real perpetual core: as long as there are people on a 7 days on, 7 days off roster verif the sector collective agreement above 3,500 metres prob minimum operating altitude declared by the camp's medical coordinator there is a fitness examination, surveillance and transfer, and the fitness market grows with every plant that enters operation. The fall when the window closes is from around USD 6 M to around USD 3 M a year estim our own calculation over our own model, not to zero. It is one of the few markets in the province with no cliff when the construction window closes.
A fatal event within a contracted service transfers the legal exposure to the provider, and at high altitude the probability is not theoretical. For a small company, the civil liability premium and the backing capital can be the filter that leaves it out even with the equipment and the staff in place. No public reference was found for premiums in this segment in the province unconf our own search with no result: it is a cost that has to be quoted before promising a response time.
A civil and commercial court in Salta ordered in July 2026 an attachment and account freeze against a lithium operator over claims by Salta contractors prob trade press. The mining companies' payment terms in the province are not public data unconf unpublished figure. For a health provider, which pays medical cover and ambulance crews every month against monthly certifications, that is the real economic risk and not the clinical one.
The medical airstrip at the province's largest camp is weather-limited prob interview with the medical coordinator. From the salt flat to the city of Salta is between 300 and 400 kilometres over a road with gravel stretches prob secondary source, that is between 6 and 8 hours of ground transfer estim our own calculation. An air service that cannot fly on the days it is needed does not get paid for, and a ground transfer of that duration changes the whole clinical protocol: it forces stabilization on site instead of evacuation, which is exactly what makes the on-site cover expensive.
The Supreme Court took original jurisdiction on 17-10-2025 prob in the amparo brought by the communities of the Salinas Grandes and Laguna de Guayatayoc basin, with an injunction suspending permits that was still awaiting resolution as of the Aug-2026 cutoff prob national press and a communication from the co-plaintiff organization. The community protocol for that basin states in its own text that it covers the departments of La Poma and Los Andes in Salta verif text of the community protocol. It does not touch the salt flats of the firm ring today, which are in other basins, but it is the only front with the capacity to halt permits in the province, and fewer permits means fewer people up there.
To qualify as a local supplier you need an actual, registered and tax address in the province, at least 80% of the payroll with an actual address in Salta, professionals licensed with the provincial association and at least 51% Salta share capital verif text of the provincial mining promotion act opened in the official gazette. And an international body documented that Salta's training deficit is precisely in health: university nursing, a nursing degree and health technical diplomas verif sector study read. There is no 80% of Salta altitude health staff waiting around. The legal release valve exists -the joint venture with a Salta partner from 30% verif same legal text- but it is a vehicle, not a solution to the underlying problem.
People exposed times the frequency of the check times the tariff, in three separate blocks because they are three different markets. Here capex is not the driver: the anchor is how many people are up there, not how many dollars are invested, and that is why this number moves with headcounts and not with investment decisions.
This calculation already carries four checks of its own and states which ones have an external anchor, so what is useful here is not to repeat them but to go at the piece none of them covers: all four look at fitness testing and surveillance, and the emergency and medical transport block —which is 40% of the headline— was left without a second route. It is also the worst anchored: its accident rate is a pure assumption because no public figure exists for the province, and three searches came up empty. (a) The emergency block against the shared package at the salt flat next door, and this is the path that bites. Here emergency and transport are worth USD 2.3 M/year over 3,500 concurrent people, that is USD 657 per person per year. Catamarca prices its shared package —helicopter on standby plus rescue brigade— at USD 1.7-6.9 M/year over some 3,000, that is USD 1,433: this page counts 54% less. The gap is not a disagreement but a difference in content that both pages declare: Catamarca counts a helicopter and this page does not — the block here is advanced life support ambulances on standby plus per-event transfers, with barely 15% by air. What is interesting is what happens when that gap is closed: the USD 776 per person of difference, applied to the Salta roster, come to USD 2.7 M/year, and added to the midpoint give USD 8.4 M — practically the ceiling of the published band, which is 8.5. In other words, this TAM's ceiling is not a loose assumption: it measures, almost to the dollar, the air asset the province does not yet have. And that reframes how to read the niche: the ceiling is not reached by selling more medical exams, it is reached the day someone puts a helicopter in place. (b) Total per capita across provinces, using the scale law the twin itself declares — plus a warning about the result. Here contractable spend per concurrent person is USD 1,629. Catamarca states ~USD 1,900 net of the helicopter, over 3,000 people. And it also states the mechanism that makes them comparable: cost per person falls as headcount rises, because clinic, brigade and standby crew are fixed costs. Scaled by that rule to the headcount here, the Catamarca figure gives USD 1,629. It is the same number, and that is precisely why it should be distrusted: these are two midpoints chosen by judgement inside bands running 3.5 to 8.5 and 3 to 9, and two rounded figures. Agreement to the dollar is fortunate, not significant, and presenting it as precision would be exactly the vice this work avoids. What does count, and it is not nothing: the two calculations were built by different methods —roster times tariff here, sites times package there— and land in the same order of magnitude with the scale effect pointing the right way. (c) Weight within the province: it does not discriminate, and here it can be demonstrated why. This market weighs 2.49% of the USD 229.3 M/year of Salta's nine investor markets and its twin weighs 3.45% of Catamarca's 167.9. The gap looks like 39% and is entirely the denominator: corrected for the size of each basket, the Catamarca share is equivalent to 2.53% here, against the actual 2.49%. What is informative is not the share but the absolutes: USD 5.7 M against 5.8 M, differing by 1.7% — two neighbouring provinces, with similar headcounts and different methods, sizing the same market at the same number. What still stands: the fitness and surveillance blocks were already backed by check (4) of the method itself; what this pass adds is that the emergency block —40% of the headline and the worst anchored— is now framed by the twin, and that the band's ceiling has identifiable content rather than being slack. What remains unresolved is what the calculation already declared and no twin can fix: no published mining accident rate exists for Salta, and without it block C rests on an assumption, however well framed.
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.
This market is not sized by dollars invested but by people, so the whole calculation hangs off a single question: how many people are exposed to high altitude. People concurrently on site were counted —direct plus contractors at the site— and never *jobs supported*: the same source that declares three thousand direct and indirect jobs for a project also declares more than eleven thousand six hundred jobs supported, because it counts up to four per position. Site by site, and everything on the lowland is excluded by definition: the industrial park is at 800 metres and another point of the corridor at 1,350, and there you have ordinary occupational medicine, not altitude medicine. The midpoint adopted is deliberately below the arithmetic mid-point, because the ceiling assumes a simultaneity of peaks between sites that no source establishes. Then comes the conversion from concurrent people to a roll of unique persons, which is where this calculation parts company with the camps one. The two documented rosters of the Salta puna require two crews —seven days by seven with twelve-hour shifts, and fifteen by fifteen with ten effective hours in construction—, both read in their own instrument. The factor that converts them is a declared assumption: the sector's real turnover in the province is not public data. And a clarification that has to be made because the confusion would be expensive: that total is for the whole province and not for one site — the model's table opens it site by site, by name. The external check, which is the one that counts most because we did not produce it: the spend per person implied by this calculation's two recurring blocks —fitness plus surveillance— is USD 470 per person per year estim our own calculation: it is what our own price and frequency assumptions imply, not an observed price. Catamarca anchors exactly the same block at USD 250 to 600 per worker per year estim explicit assumption of that body of work, and it got there by a different route: calibrating it as 0.7 to 1.9% of a miner's annual labour cost, over the official registered employment series. Our number falls inside that band without having been built to fall there — another province, another method, another source. It is the firmest support the two blocks that carry most of the total currently have. What is declared unresolved: the headcount of the two borate mines is not published, and that of one of the salt flat plants has a deliberately wide band because its source places the site in the area common to both provinces while the company's industrial complex is down below, where there is no altitude medicine.
