High-mountain road works and earthmoving (San Juan)
There is more road than there are contractors. In April 2026 Vicuña terminated segments E-F of the Northern Corridor —50 km at +3,500 masl, a package competitors valued at USD 70-80 M— because the winning joint venture bid 30-35% below market and could not execute; the maintenance tender reserved for San Juan firms drew barely 6 bidders. Vicuña's permanent access is a 220 km road —the largest mining road project under way in the country— and the Los Azules Feasibility budgets USD 93.6 M for accesses alone. The filter is no longer price: it is proven high-altitude capability, exactly what the termination proved is scarce.
The TAM is activity, not capturable spoils. Pre-stripping is done by the operator with its own fleet and the EPCM bundles part of the earthworks toward its global panel: that is captive. Your real gap is the access road works, the platforms and the gold leach phases, where the San Juan precedent is unanimous —no global player ever won a road—: the addressable segment.
This niche's driver is provincial: San Juan's Local Mining Development Law reserves part of mining procurement for the local supplier and turns provincial qualification into a competitive advantage. Each rule opens in the reforms panel on the home page, with its status and primary source.
enablesSan Juan: 80/60 local mining procurementRequires directing 60% of mining procurement to registered San Juan suppliers —provided they offer competitive terms—: it enlarges the local contractor's addressable market and makes the RE.PRO.MIN seal the key to enter the copper majors' quota.see the reform →This market does not float on its own: concrete megaprojects drive it.

split
The most established in mining earthworks: Veladero's Phase 8A valley leach (earthworks + geosynthetics + HDPE) active today, works at Gualcamayo
Full maintenance Angualasto-La Majadita (170 km, 13 months, ~100 jobs); won the tender reserved for San Juan firms
Terminated Apr-2026 on segments E-F for non-performance after bidding 30-35% below market; its fall IS the market vacancy
Veladero track record (Phase 6, lime plant); no known new road contract
Techint appears in the Los Azules FS as a contributor (a threat of entry from above); the A-D awardees are the map's key information gap. PowerChina: 0% in roads but proved in camps that global pricing competes
Don't fight for the pre-stripping or the EPCM package —that belongs to the operator and its global panel—. Enter from the side, where the filter is not price but proven high-altitude capability:
Target the re-tender of segments E-F (Aug-Sep 2026): it is the nearest check and at market price, and the vacancy is already on the table. Demand won't wait — Los Azules awards its 140 km road this very year.
As a work-front subcontractor to a national awardee (Milicic, Contreras, Techint) or in a joint venture: rock blasting, culverts, minor bridges. It is the door for the entrant with no Andean track record.
Recurring road maintenance (Zlato is billing 170 km today, 13 months, ~100 jobs) as an anchor that annualizes the SME — and survives the end of the construction wave.
~25-35% (USD 80-150 M/year at peak): pre-stripping and mine movement with the operator's own fleet (part of the USD 1.0 B 'Mine' line in the ITS), packages that Fluor/EPCM bundles with the plant toward its global panel, and the residual risk of an integrated Chinese EPC (less likely in roads than in camps: the work demands people and equipment acclimatized on site)
~65-75% (USD 200-300 M/year at peak), addressable by a local/national contractor: all access road works (unanimous precedents: Zlato, Semisa-Terusi, Milicic, Contreras — no global player ever won a road), platforms/camps, gold leach phases and recurring maintenance. The 60%-procurement Law + RE.PRO.MIN enlarge the local SAM, BUT with the 'competitive market terms' escape valve: the legal SAM is not real SAM without capability
USD 20-50 M/year capturable by ONE new entrant in 2-3 years: a typical package (E-F re-tender or 1-2 A-D segments, USD 30-80 M over 16-24 months) + a recurring maintenance contract that annualizes it; scalable to 50-100 M/year toward Pachón (2029+) with proven execution
effect
Jobs: ~100 direct per contract (Zlato 100, E-F ~100, Pachón bridges 120 with 90% from Calingasta), Los Azules road peak ~400; the full niche sustains ~1,000-2,000 construction jobs at the 2027-2029 peak estim, concentrated in Iglesia, Jáchal and Calingasta. Premium trades the work trains and operations retains: high-altitude road-machine operator, rock driller-blaster, winter snow-clearing operator, work-front heavy-fleet mechanic. Training gap: San Juan has no school for mountain heavy-equipment operators (today imported from Mendoza/Chile) — exactly what the 80%-local-employment Law will require to be measured. Linkage: heavy-fleet workshops/tire shops, aggregates, fuel, on-front catering, valley lodging (Iglesia has no formal hotel), personnel transport; and the asset stays: the mining road is also the communities' road (Angualasto-La Majadita is impassable in winter today). Symmetric risk: wave employment (not perpetual) with a post-2030 hangover and no reallocation to maintenance, and an SME over-leveraged on a single contract can repeat Semisa-Terusi.
calculate it
Concentration Low-to-medium and transitory: no player exceeds ~20% and 40-50% of the market is unawarded (E-F re-tender Aug-Sep 2026 + segments A-D in tender since Jan-2026 + Los Azules road + Pachón 2029). The structure will settle in 12-18 months; the hard fact on supply scarcity: the road tender reserved for San Juan firms drew only 6 bidders and the most critical package was won by a joint venture that bid 30-35% below market and was terminated.
The obvious name —“the mine”— is not a single door. In high-altitude mine construction the money comes in through different channels, and knowing which one is yours is the first step:
Vicuña tenders the road works directly, not via EPCM: the operator contracted the Semisa-Terusi joint venture and the operator terminated it. Los Azules awards its 140 km road in 2026.
Part of the earthworks goes inside the package Fluor/EPCM assembles with the plant works and assigns to its global panel; the rest is tendered by the operator. The Los Azules Feasibility budgets USD 331.6 M for the heap leach.
It's not “what breaks it”: it's the dashboard to enter at the right moment. In this niche, the work signals before anyone else — in the projects' tender flow.
Each segment is tendered before it is awarded and long before it is executed: whoever follows the process —E-F re-tender (Aug-Sep 2026), segments A-D, then the 140 km Los Azules road and El Pachón's accesses— sees the work demand months before it becomes a contract. Vicuña's FID, expected for end-2026, is the trigger for the on-site peak (~60% of TAM).
Lundin Mining — Vicuña project news (Northern Corridor, by event) ↗For the cycle's macro tempo: the copper price (LME, daily) rules over El Pachón and Los Azules —copper below USD 3.5/lb re-sequences the wave—, while Vicuña Stage 1 is robust to the study's prices. A cycle gauge, not the real-time San Juan figure.
Final decision expected end-2026; without an FID, segments A-D and the on-site peak (~60% of TAM) slip. RIGI approved Jun 16, 2026 and a USD 4,500 M credit reduce the risk but do not remove it. It is the nearest killer
2027-2029: copper <USD 3.5/lb re-sequences Los Azules (IRR 19.8%) and above all Pachón (FID 2029, the most uncertain leg); Vicuña Stage 1 is robust. Shrinks the TAM ~30-40%
Recurring throughout the window. Real precedent: a Chilecito injunction cut off the Guandacol access for a month (Apr-2026). Josemaría's environmental permit (DIA) approved (Mar-2026) but INA-CRAS questions the pumping and 'Jáchal No Se Toca' remains active: an amparo can halt the work front, not just the mine
2026-2028: a Chinese EPC with its own road-building arm would capture whole packages; the camp (USD 52 M vs 70 M) proved that a 25-35% difference moves the needle. Mitigated by acclimatization/logistics and scorable local procurement
Work executable ~Oct-May: a delayed award loses the year (already happened with E-F, winter 2026). And the bulk of the TAM is 2026-2030 with a Pachón tail 2029-2034; afterward a perpetual maintenance core of only ~USD 20-40 M/year estim remains — it is a wave, not an annuity
The figure holds up along two converging paths. The simplest to watch is top-down: how much is built per year in San Juan, times the share that is road works and earthmoving.
The by-package calculation —Vicuña's Northern Corridor + Los Azules accesses and heap + Veladero phases + El Pachón's start + recurring maintenance— adds up to ~USD 1,100-1,500 M over the 2026-2030 window, with the 2027-2029 annual peak at ~USD 300-400 M. The two paths, bottom-up and top-down, give the same result.
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 floor of the figure comes from hard data we opened at the official source: the Los Azules Feasibility budgets USD 93.6 M for accesses and USD 331.6 M for the heap leach —earthmoving-intensive work—, and Vicuña's technical study describes a 220 km road with USD 7,100 M of Stage 1 capex. On those anchors we build the market from the bottom up, package by package, with a real reference price: the USD 70-80 M competitors bid for the 50 km of segments E-F. The annual total is our own estimate —we say so plainly— and we cross-check it against the province's simultaneous mining capex: the two paths converge at ~USD 250-400 M/year at the peak.
