Argentina Overhauls Mining Rules for First Time Since '93

Decree 482/2026 slashes customs delays and speeds VAT refunds, giving Argentina's copper and lithium sector its biggest shakeup since 1993.

Argentina has issued its first overhaul of the Mining Investment Regime in more than three decades. Decree 482/2026, which took effect on June 24, targets the administrative delays that have long slowed copper and lithium projects, even as fiscal incentives stayed in place.

President Javier Milei signed the measure using delegated executive authority, bypassing a congressional vote.

Customs is the main focus. Under the new rules, companies can clear imported equipment through sworn declarations instead of the slower verification process that preceded them. That change cuts lead times at the border, a frequent complaint among operators working in remote parts of the Andes.

Two other measures matter for smaller firms. Junior miners will see faster VAT refunds during exploration, easing cash-flow pressure at an early and often precarious stage. Applications for 30-year tax-stability certificates will also move more quickly, removing a source of uncertainty that had discouraged long-term investment.

Argentina's mining ministry described the decree as a complement to the existing RIGI regime, which already reduces royalties and import duties. Officials there argue that paperwork, not headline tax rates, had been the quieter deterrent. Some of the world's highest-grade lithium and copper deposits sit in Argentina; slow bureaucracy, rather than resource quality, had been holding back capital.

For companies weighing exposure to Latin America, the decree changes the calculation around Argentine assets. Shorter permitting timelines and clearer tax-stability windows lower the effective cost of capital. Mid-tier developers may find the country more attractive as a result, and larger diversified miners could follow.

Whether the reform delivers depends on execution rather than the text itself. Customs offices and provincial authorities will need to apply the new procedures consistently for the promised time savings to materialise. Demand for battery metals continues to rise globally, and Argentina is positioning itself to capture more of that investment. The extent to which it succeeds will become clearer as the first projects move through the revised process.
