First Quantum to seek Argentina RIGI tax incentives for $5.25B copper project

The RIGI application is the tell here: Argentina's incentive regime has become the gate through which large-scale copper capital decides whether to commit, and First Quantum's move signals that fiscal frameworks, not geology, are the binding constraint on undeveloped deposits. Taca Taca's scale matters beyond the company — it would be a meaningful addition to global copper supply into the next decade, a market where new mine capacity is scarce. Whether other developers follow into RIGI, and whether approval timelines hold, is the open question worth tracking.
