Resouro Strategic Metals delivers PEA for Tiros titanium-rare earth project

Toronto, Canada (ABN Newswire) - Resouro Strategic Metals Inc. (ASX:RAU) (CVE:RSM) (FRA:8TX) (OTCMKTS:RSGOF) today reported the results of a Preliminary Economic Assessment ("PEA") for its Tiros Titanium and Rare Earth Project in Minas Gerais, Brazil, as outlined in the Company's PEA Webinar presentation dated June 16, 2026. The PEA evaluates a phased development strategy commencing with a 500,000 tonnes per annum ("tpa") starter operation. The base case demonstrates strong economics with low upfront capital intensity relative to project scale and significant remaining resource for future expansion.

Key PEA Base Case Highlights (500,000 tpa Starter Operation) - Post-tax NPV (8%): US$714.9 million - Post-tax IRR: 44.2% - Pre-tax NPV (8%): US$1,138.8 million;Pre-tax IRR: 62.7% - Upfront capital expenditure: US$191.1 million (gross, including contingency) - Mine life: 20 years - Post-tax life-of-mine cash flow: US$1,673.9 million - Average annual post-tax cash flow: US$70.0 million - Post-tax payback period: 1.9 years from first production - Processing rate: 500,000 tpa ROM ore - Steady-state annual TREO in product: 3,636 tonnes - Steady-state contained TiO2 in concentrate: 90,100 tonnes per year The starter operation is based on approximately 10 Mt of the high-grade domain, representing only ~0.7% of the Project's 1.4 billion tonne Measured and Indicated Mineral Resource. Mineral Resource (effective 9 April 2025) Tiros hosts a globally significant Mineral Resource of 1.4 Bt @ 12% TiO2 and 4,000 ppm TREO in the Measured and Indicated category (including a high-grade domain of 103 Mt @ 23% TiO2 and 9,100 ppm TREO). An additional 500 Mt Inferred Resource provides further upside.

The mineralisation is near-surface weathered clay, amenable to free-digging open-pit mining and conventional processing to produce coarse and fine TiO2 anatase concentrates plus a mixed rare-earth sulphate product. Project Setting and Next Steps Tiros is located in the mining-friendly state of Minas Gerais, Brazil. The Company plans to advance infill drilling, metallurgical optimisation, product specification testwork, and progression to a Pre-Feasibility Study in parallel with a structured permitting pathway led by Sete Solucoes.

The presentation highlighted six key strategic points: strong economics, low-capital starter operation, expansion potential from the large resource base, dual-product revenue opportunity (TiO2 + TREO), simple mining and responsible design,and a clear development pathway in an established jurisdiction. *To view the presentation, please visit: https://abnnewswire.net/lnk/ZCKJL8K2 About Resouro Strategic Metals Inc.: Resouro Strategic Metals Inc.
