Argentina copper mine investment accelerates under Rigi incentive framework

Argentina copper mine

Argentina copper mine investment is entering a new phase under the Rigi incentive framework. The approval of McEwen Copper’s $2.7bn Los Azules project signals that Argentina copper mine investment is now central to the Milei government’s economic strategy. As a result, Argentina copper mine investment is being positioned as a key pillar for both fiscal reform and long-term export growth.

Rigi turns Los Azules into a flagship Argentina copper mine investment

The Los Azules project is the first copper mine approved under Argentina’s large-scale investment regime, Rigi. The scheme offers a 25pc tax rate instead of 35pc, 30 years of legal stability and exemption from import duties on capital goods. These incentives are designed to de-risk Argentina copper mine investment amid currency volatility and political uncertainty. Construction at Los Azules could begin as early as 2026, subject to permitting approvals. The mine is expected to produce about 175,000 t/yr of copper, placing it among the country’s most significant future producers. This scale matters for Argentina’s balance of payments, because copper exports can provide stable hard-currency revenues.

Copper anchors Argentina’s wider energy and mining investment push

The Los Azules approval is part of a broader Rigi pipeline that already totals $15.7bn in committed projects. The portfolio spans two solar plants, two lithium mines, an oil pipeline, an LNG facility and a steel mill. Together, these projects illustrate how copper, lithium and energy infrastructure are being bundled into a single strategic investment narrative. The government is targeting at least $50bn in energy investment and another $50bn in mining by 2027. That timeline aligns with president Javier Milei’s current term and his wider macroeconomic adjustment agenda. At the same time, Argentina is courting external financial support, including a potential $20bn currency swap backed by the US government. Stable capital inflows are critical to sustain Rigi and reassure foreign mining investors.

The Metalnomist Commentary

Los Azules shows how targeted tax stability and customs relief can unlock large-scale copper capex even in a risky macro environment. The challenge will be execution: permitting, infrastructure delivery and social licence will determine whether this project hits its 2026–27 window. For the global copper market, Argentina’s success or delay at Los Azules will shape future supply expectations in the second half of the decade.
