Brisbane-based mining company Elementos is advancing its $250 million Oropeza tin mining project in western Spain, positioning the venture as a critical development for Europe's tin supply and the broader green energy transition. The project, located near the Portuguese border, aims to establish Europe's only advanced tin mine alongside a vertically integrated supply chain—an initiative that could supply approximately 10 percent of the continent’s tin demand at its peak.

Elementos is also pursuing a 50 percent stake in the nearby Robledallano smelter, which is operational but requires further investment to expand its processing capacity. The dual approach of mining and smelting development is intended to strengthen supply security within Europe, a region that currently imports all of its tin, largely from Asia.

The Oropeza project has garnered significant regional support, particularly from the Andalusian government, which has designated tin as a priority raw material. This backing was reinforced recently when the project obtained “Override Public Interest” (Interés Público Superior) status, expediting environmental and planning approvals. In Spain, where regional authorities wield considerable influence over mining approvals, this status is seen as a critical milestone.

To mitigate risks and bolster the project’s prospects, Elementos has formed partnerships with major European resource firms, including Swedish mining company Boliden and Norwegian recycling specialist Norsirk. These co-investors contribute technical expertise and assist in securing export markets, reinforcing the project's viability amid increasing concerns about the stability of long supply chains from Asia.

Tin's industrial applications extend beyond traditional uses such as tin cans and roofing materials. More than half of global tin demand last year—approximately 52 percent—was attributed to electronic solders, which are essential for assembling circuit boards and other electronics. Emerging technologies are also driving new demand; tin is gaining attention for its potential role in sodium-ion batteries, adding to its strategic importance in clean energy technologies.

Joe David, Elementos’ managing director, described tin as a "major enabler" of green technologies, highlighting the metal’s critical role despite its relatively low profile compared to copper, nickel, and lithium. He noted that tin is often overlooked but is fundamental to the global energy transition, serving as the "glue" in electronic components and an important input for future battery innovations.

With Europe seeking to enhance its raw material self-sufficiency and reduce reliance on external suppliers amid geopolitical uncertainties, the success of Elementos’ Oropeza project could have wide-reaching economic and strategic implications. The initiative underscores a broader shift toward securing critical minerals domestically and regionally to support the growing demand for renewable energy technologies and electronic infrastructure.
