Continuous High-Grade Titanium and Rare Earths Mineralisation
Results from Tiros Central Drilling Campaign
Resouro Strategic Metals Inc. (ASX: RAU; TSX-V: RSM; FSE: 8TX; OTCQB: RSGOF) ("Resouro"
or the "Company") is pleased to announce the remaining results from the infill drilling campaign
undertaken at its Tiros Titanium and Rare Earth Elements Project in Minas Gerais, Brazil (“Tiros
Project” or “Tiros” or “Project”).
Highlights
• Results for the remaining 32 infill and step -out diamond drill holes from the Tiros Central
Project demonstrate s ignificant mineralization of titanium and rare earth elements in all
holes.
• 72% of holes contain high-grade mineralisation defined using a cut-off grade of 6,000ppm
Total Rare Earth Oxide (“TREO”) and/or 16% for Titanium Dioxide (“TiO2”).
• A total of 1,891m drilled with the following selective significant intervals:
• 54m at 13.04% TiO2 and 3,593ppm TREO from surface down hole in FDTIR-49:
o Including 3m at 26.05% TiO2 and 7,936ppm TREO from 5m.
• 50m at 12.80% TiO2 and 4,491ppm TREO from 17m down hole in FDTIR-50:
o Including 6m at 25.34% TiO2 and 10,036ppm TREO from 23m.
• The region selected for this campaign is confirmed as highly prospective, due to the
elevated grades and the thin cover of overburden.
• The Company is now in the process of finalising the mineral resource estimate update for
the Tiros Central Block based on the new drill assay information.

The infill and step -out campaign, developed after the publication of the Mineral Resource
Estimation (“MRE”) in July 2024 (refer ASX announcement 18 July 2024/T SXV 17 July 2024 ),
consisted of 46 drill holes for 2,922m at the Central Block at Tiros. The results for 14 holes have
been previously published while this announcement refers to a batch of 32 holes, for 1,891m drilled.
The selection of notable intervals is made 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.
Table 1 below lists the intervals with the above cut-off grade criteria with significant titanium and
rare earths mineralization in all drill holes. The high-grade zone is identified in 23 drill holes, or
72% of the holes being reported. This proportion is higher than the anticipated ratio of occurrence
indicating that the region selected for the infill and step-out drilling is a highly prospective region.

Commenting on the results of the latest assays from the infill and step-out drilling, Resouro’s CEO,
Alistair Stephens, said:
“We continue to see world-class assay results from near-surface at the Tiros Central Project. These
results will be used for a review of the mineral resource estimate that we anticipate will be
published in the near term . O utcomes of metallurgical test works that are also very close to
finalisation.”
Figure 1, below, is a map of the Tiros Central block, indicating the holes used in the current MRE,
in red, and the infill and step-out drilling campaign, in blue. Two valleys in the northern part of this
block were selected for t his campaign, due to the ir thin overburden and high grades of TiO 2 and
TREO. Much of this area was not included in the MRE reported in July 2024.

with assay intervals for TiO2 and TREO grades. The vertical axis of this figure is exaggerated by a
factor of three. This clearly demonstrates that the horizon of high-grade mineralisation (red lines)
occurs in the upper part of the mineralized layer.

The drilling reported is located in a valley primarily used for cattle grazing, with a high-capacity
350 kV power line visible in the foreground of Figure 3. The location is well served by roads and
water.
