Ivanhoe Mines Announces Completion of Three Major Project Milestones at the Platreef Platinum-Palladium-Nickel-Rhodium-Gold-Copper Mine

Executive Summary of April 23, 2026 Release

• Ivanhoe Mines announced completion of three major development milestones at the Platreef Mine in South Africa.
• Shaft #3 Completion: Construction finished on schedule in late March 2026; increases total hoisting capacity five-fold to ~5.0 million tonnes per annum (Mtpa).
• Phase 2 Concentrator: Groundbreaking occurred April 9, 2026; targeted for completion by end of 2027 with expected production >450,000 oz 3PE+Au.
• Shaft #2 Widening: Construction commenced to widen shaft from 3.1m to 10m diameter; ready for labor/materials by end-2028 and ore hoisting by end-2029.
• Economic Projections: Phase 2 life-of-mine total cash cost estimated at $599 per ounce of 3PE+Au (net of nickel/copper credits). Phase 3 projected to reduce costs further to $511/oz.

Evaluation of Surprise Factor

• The completion of Shaft #3 was explicitly anticipated in January and February 2026 guidance ("On schedule for ready-to-hoist status in April"). Confirming this milestone does not introduce new information that alters the fundamental valuation thesis.
• Phase 2 expansion details (groundbreaking, cost estimates) were largely consistent with the Integrated Development Plan referenced in November 2025 and January 2026 updates.
• The news serves as a validation of execution rather than a catalyst for re-rating.
