TSXV Release ASX Release
13 August 2025 14 August 2025
Tiros Northern Block Assays Results up to
22.4% TiO2 and 13,074 ppm TREO
Resouro Strategic Metals Inc. (ASX: RAU; TSX-V: RSM; OTCQB: RSGOF; FSE: 8TX) ("Resouro" or
the "Company") is pleased to announce the remaining assay results from the auger drill hole
program undertaken at the Northern Block of the Tiros Titanium and Rare Earth Elements (“REE”)
Project in Minas Gerais, Brazil (“Tiros Project” or “Tiros” or “Project”).
Highlights
• 5 m at 22.4% titanium dioxide (“TiO2”) and 7,146 ppm Total Rare Earth Oxides (“TREO”)
from 2 m in FT-48;
• 3 m at 12.3% TiO2 and 13,074 ppm TREO from surface in FT-53; and
• 4 m at 23,9% TiO2 and 7,427 ppm TREO from 8 m in FT-63.
The eighteen auger drill holes in this release complement results from previous auger drill holes
FT-26 to FT-47, announced in April 2025 1, which confirmed the presence of a high-grade, near-
surface zone within the Tiros Northern Block.
• 16 of the 18 auger holes intercepted significant mineralization.
• Assays identified mineralization down to a maximum auger depth of 15 meters.
• Despite the excellent results at the Tiros Northern Block, the current focus remains on the
Tiros Central Block, where metallurgical test work and engineering studies are underway
to support the development of a d emonstration plant (refer ASX announcement of 12
August, 2025 / TSXV 11 Augus t, 2025). The Company’s focus reflects the logistical and
infrastructure advantages of the Tiros Central Block.

of 22 April, 2025 / TSXV 21 April, 2025.

NEXT STEPS
With auger drilling now complete at the Tiros Northern Block, the Company remains focused on
advancing metallurgical programs currently in progress at CIT-Senai and SGS Laboratories in
Brazil and Canada.
ASSAY RESULTS
All assay intervals (Refer Table 1) are determined using cut-off grades of 1,000 ppm for TREO and
6% for TiO2 while the high -grade zone is defined using a cut -off grade of 6,000 ppm for TREO
and/or 16% for TiO2.
These results from the Northern Permit area of the Tiros Northern Block confirm the continuity of
high-grade mineralisation, which is either exposed at surface or covered by a thin layer of
overburden.
All intervals are interpreted as representing the true thickness of the mineralization. The orebody
is horizontal and all holes are vertical.

The Tiros Northen Block, Figure 1, is a plateau, where the Capacete Formation is preserved. Auger
holes were located along the rim of the plateau, in zones where there is no or little overburden.

The geological map of the Capacete formation, Figure 2, demonstrates the relationship between
mineralization and overburden.

The photo below shows the region where the high -grade zone crops out. The top of the plateau,
visible in the background, is covered by overburden over the Capacete Formation, with a thickness
of approximately 20 to 25 meters. In contrast, the valleys in th e foreground expose the
mineralization without any overburden, making them a favourable location to initiate a mining
operation.

Christopher Eager, Executive Chairman and CEO commented:
“Resouro is pleased to report additional high -grade drill intercepts near surface at the Tiros
Northern Block. The Northern Block is over 18 km to the north of the Tiros Central Block that hosts
the 1.4 billion tonnes NI 43 -101 Measured and Indicated Resource at a grade of 12% TiO2 and
4,000 ppm TREO as reported by Resouro in April 20252. These results provide further evidence of
the remarkable continuity and size potential of the global exploration target at Tiros.”
This announcement has been authorized for release by the Board of Directors.
