Vicuña Corp. Applies for RIGI PEELP in Argentina

Lundin Mining said Vicuña Corp. submitted an application on Dec. 11, 2025 to Argentina’s RIGI PEELP for the Josemaria and Filo del Sol deposits, a key step to secure long-term fiscal stability and incentives for a district-scale, multi-decade copper‑gold‑silver development that Lundin (50% via Vicuña) and partner BHP are advancing. RIGI PEELP—the first mining project to apply—offers extended 40‑year benefits including lower corporate and dividend withholding taxes, export‑duty exemptions, VAT offsets and accelerated repatriation, which could materially improve project economics and support staged, shared‑infrastructure development; an integrated technical report is expected in Q1 2026. The application materially de‑risks fiscal and repatriation exposure but the company notes standard forward‑looking risks including permitting, market, political and operational uncertainties.

Analysis

Lundin Mining announced on December 11, 2025 that Vicuña Corp. has submitted the Vicuña Project (Josemaria and Filo del Sol) for Argentina’s RIGI PEELP designation; Lundin holds a 50% interest via Vicuña and is partnered with BHP, and an integrated technical report is expected in Q1 2026. The filing is the first mining project to seek RIGI PEELP status and specifically requests the regime’s longer 40-year benefit period (versus 30 years under standard RIGI) and accelerated repatriation advantages.

RIGI PEELP offers lower corporate and dividend withholding tax rates, removal of export duties, VAT offsets and faster revenue repatriation, which the company says could materially enhance project economics and support district-scale, staged development with shared infrastructure. These fiscal lifts are a de‑risking step for capital-intensive, multi-decade copper-gold-silver development but are contingent on approval and implementation details that will be disclosed in the forthcoming technical report.

Market signals show moderately positive sentiment (0.45) and limited near-term market impact (0.35), with stronger positive reaction for LUN.TO (0.5) than for BHP (0.15). Key near-term catalysts are RIGI approval, the Q1 2026 integrated technical report, permitting progress and financing; material risks cited in the release include permitting delays, political/regulatory uncertainty, commodity price exposure, cross-border operational complexities and standard development execution risks.

Key Decisions for Investors

• Adopt a constructive but cautious stance on Lundin Mining (LUN): consider selective accumulation ahead of the Q1 2026 integrated technical report and any RIGI approval, but avoid increasing position size materially until those milestones and financing clarity are achieved
• Monitor three primary triggers—RIGI approval progress, the Q1 2026 integrated technical report outcomes, and major permitting/financing milestones—and re-rate the position if the technical report quantifies materially improved project economics or RIGI benefits are formally granted
• Limit downside exposure given multi‑year execution risk by sizing positions conservatively and using hedges or position limits if copper/gold price exposure is significant
• Watch partner BHP commentary and Argentine/provincial government signals for sustained political support, as successful execution depends on intergovernmental and cross‑border cooperation
