Resouro Announces Filing its Year End Reports and Publishing its Inaugural Sustainability Report

Resouro Strategic Metals Inc. ("Resouro" or the "Company") is pleased to announce that it has released the Financial Statements and Management’s Discussion and Analysis for the year ended March 31, 2025. The reports are available under the Company’s profile on SEDARplus (www.sedarplus.com) and the Company’s website (https://resouro.com).

Resouro is pleased to announce that it has published its first Sustainability report, which can be found on the Company’s website (https://resouro.com/about-us). We have begun our journey to formalize our strategy to support the wellbeing of people and the environment as we develop our mining projects. We are convinced that effectively integrating our Sustainability Governance strategy into the fabric of our corporate culture will not only drive long-term value for stakeholders but will also strengthen our resilience to position us as a sustainable leader in the titanium and rare earth mining sector.

Fiscal Year Summary

FY25 marked a pivotal year for Resouro, as we transitioned from a single-market explorer to a dual- listed strategic metals developer with growing global recognition. The year began with a successful ASX listing, which enabled us to aggressively advance exploration at our flagship Tiros Titanium and Rare Earths (REE) project in Brazil (Tiros or Project), a project the Board believes has the potential to emerge as one of the world’s most significant sources of titanium and critical minerals.

The capital raised through our ASX IPO allowed us to accelerate drilling and development activities, with early success validating the geological potential of Tiros and positioning Resouro as a serious emerging player in the global critical minerals landscape.

Achievements

Resouro achieved several key milestones throughout the Financial Year, with a selection of the most notable in order of occurrence across FY25 being:

Subsequent to the end of FY25, the run of achievements continued with the following key milestones:

Maiden JORC MRE and Updated JORC MRE

Our Maiden JORC Mineral Resource Estimate (MRE), for the Tiros REE project announced on 18 July, 2024 delineated a 1.7 billion (bn) tonne resource. This placed the Tiros Project as one of the largest undeveloped titanium and rare earth resources not only in Brazil, but globally.

The MRE was surpassed in April 2025 with an updated MRE. The updated MRE (Measured and Indicated), applying a 1,000 pm Total Rare Earth Oxide (TREO) cut-off, presents 1.4 billion tonnes at 12% TiO2 and 4,000 ppm TREO containing 1,100 ppm Magnet Rare Earths Oxide (MREO) with a highgrade zone identified as summarised in the table below. Drilling data to support the high-grade (HG) and medium grade (MG) is detailed in the JORC Table 1 in Appendix 2 of the Company’s announcement to ASX on 9 April, 2025 along with all relevant data to support the Updated MRE.

Ø Measured and Indicated Resources increased by almost 37% to 1.4 billion tonnes:

• Measured Resources 367 Mt at 12% TiO₂ and 4,100 ppm TREO,
• Indicated Resources 1,000 Mt at 12% TiO₂ and 4,000 ppm TREO,
• Total Resources 1,400 Mt at 12% TiO₂ and 4,000 ppm TREO

Ø High-grade mineralisation within the MRE:

• Measured Resources 30 Mt at 24% TiO₂ and 9,300 ppm TREO,
• Indicated Resources 74 Mt at 23% TiO₂ and 8,900 ppm TREO,
• Total Resources 104 Mt at 23% TiO₂ and 9,100 ppm TREO

This positions Resouro among the most advanced and early-stage titanium and REE developers globally, with a unique combination of scale, grade, and access to infrastructure.

CEO appointment

On the management front, we were pleased to announce the appointment of Alistair Stephens as CEO in November 2024.

Alistair brings over 35 years of global mining expertise to the Company. In the initial 15 years of his career, he worked in mining operations in Western Australia for Newmont, KCGM, WMC Resources Ltd and Orica. He has successfully defined a significant global inventory of major rare earths resource deposits and been a leader in successful metallurgical test work programs, metallurgical flowsheet development and engineering designs that will be crucial in the development of Resouro’s globally significant Tiros Titanium-Rare Earths Project in Brazil.

Alistair brings a wealth of leadership experience across team building, strategic planning, corporate governance, stakeholder engagement, corporate finance, talent management, commodity marketing, and end-to-end mining and processing operations.

This positions Resouro among the most advanced and early-stage titanium and REE developers globally, with a unique combination of scale, grade, and access to infrastructure.

Novo Mundo

In addition to Tiros, Resouro has a 100% ownership and title in the Novo Mundo Gold Project (Novo Mundo) located in the Alta Floresta Gold Province, in the Mato Grass state, also in Brazil. Resouro is continuing to assess its strategic options to crystallise value from this project.

Once again, I would like to take this opportunity to thank our loyal shareholders and key stakeholders for their ongoing support, which is instrumental to Resouro on its path to success.

I would also like to thank my fellow directors, CEO, Alistair Stephens, CFO and Corporate Secretary, Sandra Evans and the technical and operations teams on the ground for their continued efforts across the year.

We look forward to another year of even greater success and achievement at Resouro.

Yours faithfully,

Chris Eager

Chairman of the Board
