High-Grade Assay Results up to 26% TiO2 and
18,887ppm TREO at Tiros North Block Support
Next Steps Toward Scoping Study
Resouro Strategic Metals Inc. (ASX: RAU; TSX-V: RSM; FSE: 8TX; OTCQB: RSGOF) ("Resouro" or
the "Company") is pleased to announce the assay results from 21 auger drill hole for 206 m of
drilling, undertaken at the North block of the Tiros Titanium and Rare Earth Elements (“REE”)
Project in Minas Gerais, Brazil (“Tiros Project” or “Tiros” or “Project”).
Highlights
1m at 22% TiO2 and 18,827ppm TREO from 8m in auger hole FT-32
1m at 25.6% TiO2 and 12,138ppm TREO from 19m in auger hole FT-28
High-grade results close to surface include:
• 7m at 23.4 TiO2% and 8,149ppm TREO from 5m depth in auger hole FT29
• 4m at 20.8 TiO2% and 14,229ppm TREO from 6m depth in auger hole FT32
• 4m at 18.9 TiO2% and 11,059ppm TREO from 5m depth in auger hole FT42
The recent update of the MRE for the C entral Block MRE of 1.4 Billion tonnes of Measured
and Indicated Resource contains 165 Mt of titanium dioxide (TiO₂), and 5.5 Mt of Total Rare
Earths Oxide (TREO) at a Magnet Rare Earths Oxide (“MREO”) ratio of 27% and is one of
the largest mineral deposits globally. An additional resource of 500 million tonne of Inferred
Resource contains 60 million tonnes of TiO2 and 1.85 million tonnes of TREO.
The current assay results add to the massive resource potential of the Tiros Project area.

NORTH BLOCK ASSAY RESULTS
Results are related to the current auger drilling campaign, designed to evaluate the areas outside
the Tiros Central block. The North block was initially chosen because earlier results from auger
drilling showed a high-grade zone close to the surface. Assay results exclude additional 18 auger
holes for 180m of drilling, from the same North block, with results pending at ALS laboratory, at
Vespasiano, Minas Gerais.
All assay intervals (Table 1) are determined using cut -off grades of 1,000ppm for TREO and 6%
for TiO2 while the high-grade zone is defined using a cut-off grade of 6,000ppm for TREO and/or
16% for TiO2. These results from the Northern Permit of the Tiros North Block confirm high-grade
mineralisation is continuous and is either exposed at surface or covered by a thin layer of
overburden.

seen in the background, has overburden covering the Capacete formation, with a thickness in the
order of 20 to 25 m. The valleys, as depicted at the front part of this p hotograph, shows the
mineralization without overburden that is a favourable location to start a mining operation.

NEXT STEPS
Resouro will produce a Resource Statement and develop a mine plan to complete a Scoping Study
in support of a Trial Mining License application. Work has begun on the Environmental Impact
Study required as part of the licensing process. The objective of the Scoping Study is to generate
bulk samples of raw, unprocessed material from the North Block , targeting very high-grade, near
surface, friable material, for distribution to potential offtake partners. This will help test market
interest in direct shipping and guide future development decisions.
In parallel, Resouro will continue evaluating the targets outside its Central block, where drilling is
currently concentrated. Exploratory drilling has confirmed the presence of mineralization in both
the São Gotardo and North blocks. The Campos Altos block will be mapped with the support of
the auger rig, to assess its exploration potential.
This announcement has been authorized for release by the Board of Directors.
