Argentina’s copper story is often framed around future output: how much metal projects such as Vicuña and Los Azules could eventually add to global supply. For mining suppliers, however, the more immediate question is different. The commercial opportunity starts years before the first tonne of copper is produced.
Vicuña, the joint venture between BHP and Lundin Mining in San Juan province in western Argentina, illustrates the point. Its phased development plan puts initial investment for Stage 1 at about US$7 billion, with first production targeted for 2030. The project is already moving from engineering into execution. During 2Q26, work focused on detailed design, execution planning, and early earthworks. A 24-truck fleet was mobilised and 1.1 million t of material were moved during the quarter.
Procurement is developing alongside those works. In August, Vicuña held a business round with more than 90 companies from Iglesia and Jáchal, the two municipalities closest to the project area, ahead of a tender for site personnel transport. That distinction matters for international suppliers: 'local' requirements may refer not only to Argentine participation generally, but specifically to companies from communities in the project’s area of influence.
The regulatory framework is also shaping procurement. Argentina approved Vicuña under the Large Investment Incentive Regime, or RIGI, as a Long-Term Strategic Export Project. The RIGI resolution records US$9.737 billion in total investment, including US$9.025 billion in eligible assets, with US$1.129 billion allocated through the end of 2026 and US$7.896 billion for 2027 to 2031. It also approves goods and services eligible for import benefits and requires a supplier development plan. For international providers, that creates a clearer framework for large capital commitments.
Los Azules, another major copper project in San Juan province, provides a second example. McEwen Copper’s 2025 feasibility study estimated initial capital expenditure at US$3.168 billion. On 27 August 2026, the company announced a US$240 million term loan to continue engineering and early works. A final investment decision and full project financing are expected in mid-2027, with commercial copper cathode production targeted for 2030. Engineering for the key process packages – solvent extraction/electrowinning, sulfuric acid, and crushing – has been awarded to Metso. The mining fleet tender is in final evaluation, while EPCM contractor selection is expected in 4Q26.
Much of the major equipment spend still lies ahead, but supplier positioning is already taking place. Qualification, technical documentation, logistics planning, and the choice of route to market can determine who is ready when packages move into execution. International suppliers may sell directly, through an EPCM contractor or principal bidder, or together with an Argentine partner.
The opportunity extends well beyond haul trucks and processing equipment. Large copper projects require power transmission, substations, roads, camps, water systems, logistics, safety services, maintenance, construction equipment, industrial electrical materials, and specialist engineering long before commissioning.
The key distinction is between future production and present project execution. Argentina has not yet returned to large-scale copper production, and final investment decisions remain critical. But procurement and early works are already under way. Suppliers waiting for the first copper cathode or concentrate shipment would be entering several years after the first commercial opportunities have appeared.
