Resouro Strategic Metals Inc. (RSGOF) Selects Flowsheet for Tiros PEA

Executive Summary

• Resouro Strategic Metals announced completion of the final step toward a Preliminary Economic Assessment for its High‑Grade Titanium and Rare Earth Elements Tiros Project in Minas Gerais, Brazil.
• After 18 months of metallurgical test work, a definitive process flowsheet has been selected to define capital and operating costs, recoveries, and product specifications for the PEA.
• The flowsheet incorporates conventional processing technologies with equipment largely sourced locally in Brazil and supports two parallel streams: coarse‑particle titanium concentrate and fine‑particle titanium powder plus rare earth sulfates.

Key Details

• Metallurgical Development: 18 months of hydrometallurgical and pyrometallurgical testing resulted in a chosen flowsheet that will be used to model the PEA’s economics.
• Process Streams:
• Coarse‑particle stream – mineral dressing, calcination/leaching to produce a high‑grade titanium concentrate for traditional markets.
• Fine‑particle stream – calcination, acid baking, and leach to generate fine titanium powder and mixed rare earth sulfate (precursor to carbonate/oxide products).
• Technical Team: Developed by Resouro’s Brazil team under Dr Lino Freitas (PhD, Extractive Metallurgy) and Steve Williams of Blue Coast Research; both have extensive experience in titanium and REE processing.
• Test‑work Facilities: Completed at SGS Geosol & CIT SENAI (Belo Horizonte, Brazil) and SGS Lakefield (Canada); additional confirmation testing ongoing at SGS Lakefield with results to be reported per NI 43‑101 standards.
• Future Work: Upcoming reporting of recoveries, mass balances, and product specifications; data will feed into the forthcoming PEA.
• Strategic Context: The flowsheet leverages conventional technologies and locally sourced equipment, aligning with Resouro’s goal to minimize capital risk and support a cost‑effective path to commercial production.

Notable Quotes

“This flowsheet was chosen because it uses a combination of conventional technologies and the majority of equipment can be sourced in Brazil,” – Christopher Eager, Chairman & CEO, Resouro Strategic Metals.
“We are continuing to test alternative technologies to include in trade‑off studies—like the recently announced MOU with Rare Earth Technologies—for the upcoming preliminary feasibility study.” – Christopher Eager
