Chile produces more copper than any other country on earth — roughly a quarter of global mine supply comes from its operations, spread across the Atacama and the Andes from the far north down through the central regions. It is also the world's largest lithium producer. Add the significant gold, silver, molybdenum, and iron output, and you have a country whose mining sector is not one industry among many but the structural foundation of the national economy. Understanding that context makes it easy to see why Expomin exists, why it draws 83,000-plus visitors, and why a serious mining equipment supplier from anywhere in the world has reason to be in Santiago every two years.

Expomin 2027 runs April 20 to 24 at Espacio Riesco in Huechuraba, Santiago. Organised by Fisa S.A., it's the 17th edition of a show that first ran in the early 1990s and has grown into the most consequential mining exhibition in Latin America, drawing participants from well beyond the region's borders.

What the 2025 Edition Said About 2027

The 2025 Expomin attracted 83,498 visitors — professionals from mining companies, equipment manufacturers, engineering firms, government bodies, and financial institutions. The show described it as placing copper investment and the industry's future at the centre of a critical moment. That framing was precise: Chile's copper sector was navigating a complicated period of rising production costs, grade decline at established operations, and the political pressure of expanding lithium nationalisation policy alongside the commercial opportunity of exploding battery supply chain demand.

For 2027, those tensions haven't resolved. If anything they've sharpened. The companies that exhibit and the buyers that attend will be working through capital allocation decisions for a copper and lithium sector that is simultaneously essential to the energy transition and under significant operational pressure. Expomin is where those conversations happen at scale, with equipment demonstrations, business matchmaking, and a full congress programme running in parallel.

The Show Format

Espacio Riesco is a purpose-built exhibition and convention centre in the Huechuraba commune, north of Santiago's central business district. Its combination of large indoor halls and substantial outdoor exhibition areas makes it well-suited to the kind of heavy equipment display that a mining show requires. Surface mining trucks, drill rigs, loaders, and processing plant components all occupy outdoor space; the indoor halls concentrate on technology, components, services, and the Expomin Congress.

The Congress runs across all five days, with over 90 speakers at past editions covering operations, technology, sustainability, finance, and regulatory developments. The format integrates conference and exhibition rather than separating them — delegates with a congress pass move between sessions and the exhibition floor throughout the week, which keeps technical conversations anchored in commercial reality and vice versa.

Quick Reference

Why Latin America Looks Different

Expomin's visitor and exhibitor mix reflects the particular character of Latin American mining. Chilean and Peruvian mine operators bring procurement authority and deep technical knowledge of high-altitude, arid-environment operations that are quite different from Australian or European conditions. Brazilian mining companies, active across iron ore, gold, and bauxite, represent another significant segment. Colombian coal and gold operations, Mexican silver and copper, and Argentine lithium exploration all contribute to a diverse regional buyer profile that no single market-focused show can replicate.

International equipment suppliers — from North America, Europe, Australia, and increasingly China — use Expomin as their primary Latin American market interface. The show's official status as the leading platform in the region means that missing it creates a visible gap in regional strategy. Companies that exhibit consistently tell the same story: Expomin is where their Chilean distributor relationships get reinforced, where their Peruvian project pipeline conversations move forward, and where their brand registers with buyers who might otherwise only know them by specification sheet.

Copper, Lithium and What It Means for Equipment

Chile's copper mines are among the most technically demanding operations in the world — high altitude, extreme aridity, hard porphyry rock, and long haul distances from pit to port. Hydraulic rock breakers are standard tools at virtually every major Chilean copper operation for secondary boulder reduction in the pit, liner scaling in processing plant, and infrastructure demolition during expansion phases. The concentration of major copper mine owners, engineering contractors, and procurement officers at Expomin makes it the single highest-density access point in the world for the Chilean hard-rock mining buyer segment. For attachment and breaking equipment manufacturers with Latin American ambitions, the biennial window in Santiago is not optional.
