Resouro Strategic Metals files PEA on Tiros project

Toronto, Canada (ABN Newswire) - Resouro Strategic Metals Inc. (ASX:RAU) (CVE:RSM) (FRA:8TX) (OTCMKTS:RSGOF) has released supplementary information in relation to its Tiros Titanium and Rare Earth Project Preliminary Economic Assessment (PEA) announced on 14 June 2026 (Canada) and 15 June 2026 (Australia). The supplementary information, issued under ASX Listing Rules 5.16 and 5.16.3, provides further detail on the mining, metallurgical, infrastructure and economic modifying factors supporting the 500,000 tonnes per annum (tpa) run-of-mine (ROM) production target and approximate 20-year mine life. It also sets out the proportions of Mineral Resource categories underpinning the production target.

Key Points from the Supplementary Information - The PEA productiontarget is based on high-grade ROM material, of which approximately 99.2% is underpinned by Measured and Indicated Mineral Resources and 0.8% by Inferred Mineral Resources. - Scheduled ROM processed over the 20-year mine life totals approximately9.534 Mt. - Initial capital cost is estimated at US$191.2 million (gross basis, including contingency). - Steady-state annual operating cost is estimated at US$109.5 million (gross basis), or US$219.0 per tonne of ROM. - Metallurgical recovery assumptions used in the PEA are 68.7% for TiO2 and 67.0% for rare earth elements (REE), based on bench-scale testwork. - The mining method is conventional open-pit strip mining using truck-and-excavator, with conservative PEA-stage assumptions for recovery, dilution and pit design parameters. The Company confirms that this supplementary information does not replace or amend the original PEA announcement. The PEA remains preliminary in nature and is equivalent to a Scoping Study under the JORC Code (2012).

There is no certainty that the outcomes described in the PEA will be realised. Full details, including tables on capital and operating costs, pit design parameters, metallurgical testwork summaries and annual ROM schedules by resource category, are set out in the supplementary information released today.
