Copper concentrate logistics and transfer node on the San Juan corridor
When Vicuña starts producing, between 80 and 90 trucks a day will come down from the cordillera, every day, each with 26 tonnes of copper concentrate in sealed containers: 800 thousand tonnes a year, bound for a port in central Chile. So says the project's own technical study, which also says what almost nobody tells: that scheme is transitional. In stage 3 the concentrate moves to a buried concentrate pipeline that shares some 290 kilometres of route with the desalinated-water pipeline —costing USD 5.36 a tonne against USD 150.45 for road freight to port— and a new high-mountain road connects the mine directly to Chile's Route 5. And the destination port, Punta Padrones, is majority-owned by Lundin Mining, one of the project's two owners. None of this bills yet: the first concentrate is scheduled for around 2030. ⚠️ And the figure circulating in the press —395 thousand tonnes— is contained copper and covers the whole mine life, not first-stage concentrate: those are not the tonnes that go onto a truck.
It is the only niche in the San Juan observatory whose market does not exist yet, and that is worth saying before anything else: Vicuña's first concentrate is scheduled for 2030.See the clocks that are running, one by one

What the market is made of
This niche's split is decided by geography and ownership, not by competition. The trunk leg and the port are in Chile — and the port is majority-owned by one of the project's owners. On this side there is a cordilleran leg, a node and a crossing, and we did not identify a single San Juan haulier with a published track record of moving concentrate in a sealed container.
The anchor fleet contract, awarded alongside the construction package and on a long term, and the whole trunk and port leg on the Chilean side, where the chain is already in place.
The relay on the cordilleran leg on this side of the pass, the transfer node with marshalling yard and weighbridge, and the border crossing services: clearance, documentary control and escort.
The transfer node with weighbridge, or the border crossing service. Both enter without buying a truck and both can be set up before the mine produces.
Why we do not put a number on it This market bills nothing today and there is no contract against which to measure an entry share: the first concentrate is scheduled for around 2030 and the fleet contract is awarded alongside the construction package, which has not been tendered yet. And the owner's own document puts a closing date on the truck scheme: it is replaced by a concentrate pipeline in stage 3. Putting an entry figure on it today would mean annualising a contract that does not exist, for a service the buyer has already planned to stop buying.
Who really pays?
Three payers, and the one most worth watching is not the mine:
The big contract is awarded alongside the construction package and goes to a firm with its own sealed-container fleet. But that winner subcontracts legs, relays and workshop — and needs to do so with provincial suppliers to meet its own local procurement targets.
It is the only part of this niche that can be built and run before there is any concentrate. And it is the object whose size changes with El Pachón's decision: if that mine chose an Atlantic route, the node on the Albardón-Jáchal axis stops being a yard and becomes a terminal.
Clearance, documentary control and escort, per shipment. ⚠️ And a route that is taken for granted and is not the project's: the technical report does not name the Agua Negra pass. The Stage 1 and 2 route is the northern access road to a port in central Chile; the Stage 3 route is a new road to Juntas del Potro. Which pass the Stage 1 trucks use to cross into Chile the document does not say: it is on a map, and the maps in that report are images.

This market does not exist yet, so what has to be watched is not a price: it is how and where the product is going to leave, and until when. Closed until around 2030, and with its closing written in the same document. First concentrate is scheduled for around 2030 and today this market does not invoice a thing. When it starts, the technical report says how: truck with a sealed container from the mine to a port in central Chile, along the northern access road, some 80 to 90 trucks a day, with shipments of 22,000 to 33,000 tonnes. And it says when it ends: that scheme «is anticipated to remain operational until the concentrate pipeline is built», which is stage 3 work — and that same stage also brings a high-mountain road connecting the mine directly with Chile's Ruta 5, bypassing the San Juan corridor. ⇒ The truck window is not the regime: it is the bridge to the pipeline.

First concentrate is scheduled for 2030. What exists today is the act of state requiring investment —Resolución 1154/2026, with a minimum-amount deadline of 31 December 2028— and a construction decision executed in stages. Any slippage in the schedule moves this whole figure.
Vicuña's own design places a concentrate pipeline only in stage 3, alongside the desalination plant and the aqueduct.
See the evidence
The specialist press writes that El Pachón's «salida natural» «no está definida» prob . If it chooses a pipeline or truck to a Chilean terminal, the transfer node on the Albardón-Jáchal axis does not get built and the largest block of the alternative scenario disappears before it is born.
Rosario, San Nicolás and Bahía Blanca are the candidates under evaluation and none has the infrastructure today. That is not a terminal detail: it is what makes the Atlantic branch unviable without a port investment nobody has committed. While that investment does not exist, the Pacific wins by default.

The northern access road climbs above 3,500 metres prob provincial press and is cut by snow: that forces intermediate stock and a stockpiling yard, which raises the operator's working capital.
See the evidence
The oxide stage produces cathodes by electrowinning, and a cathode generates no concentrate freight. The technical report publishes the split over the whole mine life: 21,261 thousand tonnes of copper in concentrate, 860 thousand in cathode and 158 thousand from the circuit that recovers copper from the cyanide solution.

The opportunity in depth
The opportunity in depth
We did not identify a single haulier in the province with a published track record of moving copper concentrate. There are San Juan firms with work awarded on the corridor, but moving concentrate is not moving gravel: it requires a tipping sealed container, shipment traceability and a spill protocol. That jump is prepared before the tender — and it is tendered alongside the construction package.
The transfer node, the yard and the weighbridge, which do not exist. It is the niche's cheapest door because it does not require buying a truck, and it is the only thing that can be set up before the mine produces. If El Pachón were to choose the Atlantic, this same object becomes far bigger, on the Albardón-Jáchal axis.
Border crossing services. Clearance, documentary control and escort over a cordilleran pass that closes with snow, and whose route the technical report does not name. It is the layer with the least capital and the most local knowledge in the whole chain.
And the gap on the other side, worth seeing: we did not identify an Argentine port that handles copper concentrate. Rosario, San Nicolás and Bahía Blanca were the candidates evaluated and none has the infrastructure. ⚠️ But here the discussion is settled from another angle: one of the project's owners owns the destination port in Chile, so the Pacific does not win by default — it wins because it is in-house.
When you get paid, and what blocks it
already in
split
The concentrate haulage contract is awarded alongside the construction package and on a long term, because it requires an owned sealed-container fleet and an availability guarantee. It is not a spot market: it is won once and held for years.
The port of Coquimbo moved in January 2026 more than 21,600 tonnes of copper concentrate and mining-project cargo prob. That side of the chain is settled and is not contested from San Juan: which is why this figure counts only the leg on this side.
They exist and already win work: a San Juan firm won the 2025 maintenance of the existing Angualasto-La Majadita road, and another is part of the joint venture that won Segment A of the Corredor Norte. But moving concentrate is not moving gravel — it requires a sealed container, traceability and a spill protocol. Making that jump is the real way in, and it is prepared before it is tendered.
The A7 Albardón-Jáchal branch line would be converted to broad gauge within the Belgrano Cargas concession. ⚠️ Pinned down on 19 Sep 2026 by reading the San Martín Line's particular conditions (PLIEG-2026-79596056, 371 pages): it appears there as OPTIONAL works —items SM 47, SM 48 and SM 49, «Track renewal with change to Broad Gauge», 167 km in three stretches between the junction (km 926) and Jáchal (km 1093)—.

The jobs it createsThe biggest effect of this niche is not the freight: it is that it forces a corridor to stay open all year round. Between 80 and 90 trucks a day —each with its empty return leg— cannot be sustained on a road that closes: they demand permanent maintenance, a marshalling yard, a workshop, a tyre shop, fuel and mechanical recovery along the route, and all of that stays in the cordillera departments.the detail on jobs and trades
calculate it
The number is our own estimate. The calculation, step by step, is below.
The full calculation, step by step
| Project | What it produces | Counts |
|---|---|---|
| Vicuña (Josemaría + Filo del Sol) | copper concentrate with gold and silver in the sulphide stages | YES |
| Los Azules (McEwen) | cathodes by leaching and electrowinning | NO — a cathode has no concentrate logistics problem |
| El Pachón (Glencore) | concentrate, but its route out is undefined | declared and NOT added |
Concentration Concentration is high, and now we know why: one of the project's two owners owns the destination port. Punta Padrones, in Atacama, is majority-owned by one of the project's two owners and already exports the concentrate of another of its mines; it is 280 kilometres from the high-mountain road and the study itself says it will be the main port once that road exists. That splits the business into two uneven halves: the Chilean one is in-house, and the Argentine one does not exist yet — there are San Juan hauliers with work awarded on the corridor, but we did not identify a single one with a published track record of moving concentrate. The window to get in is the fleet tender, which goes out alongside the construction package. ⭐ And there is a market fact published nowhere: the purchase option over 40 % of Josemaría's concentrate —held by a Japanese agency— was recently transferred to Mitsui.
The rule that moves it
Here the rule does not create the demand —the concentrate has to leave regardless— but it decides who can invoice it from San Juan:

Where the number comes from
USD 20-42 M/yr, midpoint ~USD 31 M, at steady state. And the two limits that govern: this market bills nothing today —it starts around 2030— and the document itself puts a closing date on it, because the truck is replaced by a concentrate pipeline in stage 3
See the calculation, the variables and how it was validated
The figure is built from two variables, and the first stopped being a conversion of ours: the project's technical study publishes the concentrate tonnage directly.
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
The entire size of this market hangs on one tonnage, and that tonnage is published and does not have to be derived. The press confuses contained copper with concentrate —they are different things and the difference is more than threefold—, but there is no need to convert one into the other with an assumed grade, because the project's own technical report carries the physical figure.What it publishes, verbatim, for stage 1: an average annual concentrate production of 800 thousand wet tonnes, containers of 26 tonnes and, consequently, approximately 80 to 90 trucks leaving the site per day, with shipments of 22 to 33 thousand tonnes. The rate band is applied to that tonnage, and that is where the size of the market comes from. And stage 1 is exactly the one that moves by truck, so it is the correct figure and not a part of a larger one.And the same document carries two things that change the framing more than the figure:- The destination port belongs to one of the project's owners. Punta Padrones, in Atacama, is majority-owned by Lundin Mining —one of the project's two owners— and already exports the concentrate of its Candelaria mine.- The truck is transitional. Verbatim: that route «is anticipated to remain operational until the concentrate pipeline is built». The pipeline costs USD 5.36 a tonne against USD 150.45 for road freight.✅ And we did the arithmetic ourselves, to find out whether the 800 thousand were everything or a part. The report says that in stage 1 the plant treats 64 million tonnes a year and that in year 3 it yields 195 thousand tonnes of copper in concentrate; at the concentrate grade the same document declares for that stage —27 %— and with 10.9 % moisture, that gives 804 thousand wet tonnes, against the 800 thousand it publishes. Half a point of difference. The 395 thousand tonnes quoted everywhere are a different thing: total copper —concentrate plus cathode— averaged over the first 25 years, when stage 3 has already taken the plant from 64 to 107 million tonnes a year. Over that same window the report gives 382 thousand, and over the 71 years of mine life, 314 thousand. ⇒ both figures are correct and they measure different windows, and the one that is useful to a haulier is stage 1's.What we deliberately leave out: Los Azules produces cathodes and not concentrate, so it stays entirely out; El Pachón has no defined route out and is declared and not added; and the Chilean leg does not enter either, because it is a service provided on the far side of the pass.
