Expomin 2027: Confirmed Dates, EU as Guest of Honor and Everything Known So Far

Expomin 2027 already has confirmed dates: April 20-24, at Espacio Riesco, Santiago. It's Latin America's largest mining trade show, and this edition adds a notable twist — the European Union will participate as guest of honor. Here's everything confirmed so far, plus 2025 edition figures to put the scale in context.

What Expomin is and why it matters

Expomin is the international mining suppliers trade show held every two years in Santiago. It brings together the major mining companies operating in Chile — the world's largest copper producer — with their chain of technology, equipment and services suppliers, in a space built for closing deals, evaluating innovation and forming strategic partnerships.

Unlike Exponor, which focuses on the Norte Grande region and day-to-day copper mining operations, Expomin takes place in Santiago and functions as the national meeting point connecting the mining industry with investment, technology and international cooperation.

The European Union as guest of honor: what it means

The EU's participation in Expomin 2027 is part of growing cooperation between Chile and the European bloc around critical minerals and sustainable mining. The delegation will include member countries, European mining and technology companies, research centers and academic representatives, focused on applied innovation, clean technologies, digitalization, circular economy and human capital development.

For local suppliers, this opens an added visibility window: press coverage around the European delegation tends to draw interest from outlets that don't usually cover mining in depth, extending reach beyond the usual sector audience.

Central themes of the 2027 edition

• Green transition: the role of Chilean mining in the supply chain for clean technologies and electromobility.
• Critical minerals: lithium, copper and other strategic minerals for batteries and green tech, amid growing global demand.
• Circular economy: mine waste reuse, water efficiency and more sustainable production models.
• Digitalization: automation, artificial intelligence and remote monitoring applied to mining operations.
• Human capital development: the new skills the industry needs for the next decade.

Expomin and PR/visibility opportunities for suppliers

With over 83,000 visitors at the previous edition and a European delegation set to draw both mainstream and specialized media coverage, Expomin 2027 is an unusually strong visibility window for companies that supply the mining industry. Coverage in trade outlets and business media generates highly relevant backlinks during the weeks around the event — exactly the kind of editorial context that both Google and AI models weigh when evaluating a brand's authority in a technical sector.

Pairing Expomin participation with a link building and Digital PR strategy extends that visibility well beyond the event days, reaching decision-makers who weren't physically there through sustained editorial coverage and organic ranking for sector-specific searches.
