Phase 1 production commencing Q4 this year, with Phase 2 expansion accelerated to 2027

4.1 Mtpa Feasibility Study (Phase 1 & 2) yields after-tax NPV8% of $1.4 billion and IRR of 20%, producing over 450,000 ounces platinum, palladium, rhodium and gold per annum

10.7 Mtpa PEA (Phase 1, 2 & 3) yields an after-tax NPV8% of $3.2 billion and 25% IRR, scaling up annualized production to over 1.0 million ounces of platinum, palladium, rhodium, and gold, plus approx. 25,000 tonnes of nickel and 15,000 tonnes of copper

Platreef's vast, open-ended deposit contains 42 million ounces of precious metals in Indicated Resources and 53 million ounces in Inferred Mineral Resources at 2 g/t cut-off

Ivanhoe Mines to issue Q4 and Full Year 2024 Financial Results after market close on February 19 and host a conference call for investors on February 20, 2025

Mokopane, South Africa--(Newsfile Corp. - February 18, 2025) - Ivanhoe Mines (TSX: IVN) (OTCQX: IVPAF) Executive Co-Chairman Robert Friedland and President Marna Cloete announced today that the company's subsidiary, Ivanplats, and its partners, welcome the positive and significant results from two independent technical studies completed on the Phase 2 and Phase 3 expansions of the tier-one Platreef platinum, palladium, rhodium, nickel, gold, and copper mine in South Africa.

The two completed independent studies cover the three-phase development of the Platreef mine, as shown in Figure 1. This includes an updated Feasibility Study on the Phase 2 expansion to 4.1 Mtpa of processing capacity (4.1 Mtpa FS), followed by a Preliminary Economic Assessment covering a new Phase 3 expansion to 10.7 Mtpa of processing capacity (10.7 Mtpa PEA).

The excellent results from both studies reinforce the industry-leading margins of the multi-generational Platreef mine. The estimated life of mine (LOM) total cash cost for the 4.1 Mtpa FS is $599 per ounce (oz.) of platinum, palladium, rhodium, and gold (3PE+Au), net of nickel and copper by-product credits. LOM total cash costs fall to $511 per oz. of 3PE+Au in the 10.7 Mtpa PEA. This compares with a near-multi-year low basket spot price of $1,205 per oz. of 3PE+Au, as at February 17, 2025. This ranks Platreef as the lowest-cost primary platinum-group-metals producer globally, as shown in Figure 2.

Compared with other Southern African and North American primary platinum-group metal (PGM) producers, Platreef's low cash costs are predominantly due to its unique, thick orebody. The Platreef orebody will be mined using safe, mechanized, and highly productive bulk mining methods, achieving superior economies of scale. In addition, the Platreef orebody has high grades of nickel and copper as payable by-products.
