04:52 PM EST, 12/11/2025 (MT Newswires) -- Lundin Mining ( LUNMF ) on Thursday said its Vicuna Corp joint venture submitted an application for the inclusion of the Josemaria and Filo del Sol deposits, collectively, the Vicuna Project, to the Incentive Regime for Large Investments (RIGI) under the Long-Term Strategic Export Projects designation (PEELP) in Argentina.

Argentina's RIGI is designed to attract and accelerate large-scale investment through long-term fiscal stability and transparent regulatory conditions.

"Submitting the Vicuna RIGI PEELP application is an important step in positioning the project for long-term success," said Lundin chief executive Jack Lundin.

"The RIGI framework offers a stable investment environment that aligns well with the scale, capital intensity, and multi-decade potential of the Vicuna Project. The combination of RIGI benefits, provincial support, and the quality of the Vicuna Project resource base lays the foundation for transformative value creation. Together with our valued partner BHP we look forward to continuing to build on the solid relationship with the Argentinian and San Juan governments."

Lundin Mining ( LUNMF ) indirectly holds a 50% interest in Vicuna, an independently managed joint operation which owns the Josemaria deposit in Argentina and the Filo del Sol deposit in Argentina and Chile. BHP Group ( BHP ) owns the remaining interest.

Lundin Mining ( LUNMF ) shares closed up $0.40 to $27.14 on the Toronto Stock Exchange.
