Higher-Grade Nickel Sulphides Confirmed at Zeb across multiple zones -
Mineralisation Remains Open

URU Metals Limited ("URU" or the "Company") is pleased to report assay results
and geological interpretations from a two-hole drilling programme at the Zeb
Nickel Project in Limpopo, South Africa. Drilled vertically, the holes
validate the Zeb geological model, and confirms the presence of thicker,
higher-grade nickel-copper-PGE ("Ni-Cu-PGE") horizons beneath the historic
open-pit resource and demonstrates that mineralisation remains open both along
strike and at depth.

Key Value Highlights

·      Two drillholes plus two deflections completed intersected
mineralised material in both Zone 1 and Zone 2.

·      Zone 2 Ni-Cu-PGE mineralisation confirmed to be present in a
previously untested area beneath Zone 1, confirming the geological model.

·      Thicker, higher-grade intervals beneath the historical resource

o  Zone 2: up to 2.27 m @ 0.27 % Ni, 0.17 % Cu, 2.27 g/t 3PGE+Au and 4.06 m @
0.23 % Ni, 0.14 % Cu, 1.36 g/t 3PGE+Au

o  Zone 3: up to 0.70 m @ 0.65 % Ni, 0.40 % Cu within a broader 2.73 m @ 0.39
% Ni

·      Multiple semi-massive sulphide hits confirm the geological model
and strengthen the analogy with world-class feeder conduit systems.

·      Mineralisation remains open along strike and at depth,
highlighting meaningful scale-up potential for both tonnage and grade.

The Zeb mineral system is divided into four stacked horizons: Zone 1 forms the
near-surface, bulk-tonnage nickel-bearing unit of the Lower Uitloop body that
underpins the historical Ni resource.

Zone 2, immediately beneath and adjacent to Zone 1, contains Ni-Cu-PGE
mineralisation similar to that found at Ivanhoe Mines's Platreef Mine and
Valterra Platinum's (formally known as Anglo American) Mogalakwena Mining
Complex.

Zone 3 is a feeder-style ultramafic chonolith, the geometry of which was
recently confirmed in an airborne gravity and magnetic survey.

Zone 4 broadly encompasses areas of gold mineralisation intersected in
drillholes.

Two holes (Z031 and Z033) where drilled, both at a vertical angle, and were
designed to test the true vertical depth of the mineralised sequences and test
for down-dip continuity of Zone 2 beneath Zone 1. Two deflections, Z031D1 and
Z031D2, were drilled off Z031. No deflections were drilled off Z033. Boreholes
and deflections were drilled using a NQ core diameter size. The locations of
these holes are shown in Figure 1 below.

Boreholes Z031 and Z033 successfully intersected Ni and Ni-Cu-PGE
mineralisation in Zones 1 and 2 respectively, while Z031 and its deflections
also intersected what is interpreted as Zone 3 mineralisation. The assay
results confirm the presence of thick, higher-grade Ni-Cu-PGE mineralised
intervals of varying grade beneath the historical resource envelope and
confirm the continuity of mineralisation in line with previous intersections
along strike.

Importantly, the data provides strong evidence that the Ni-Cu-PGE
mineralisation in Zone 2 continues below Zone 1 and may fully extend beneath
Zone 1, meaning that the area holds increased potential to host a significant
Ni-Cu-PGE resource. This is shown in the cross sections in Figure 2 and Figure
3.

The boreholes also intersected Zone 3 semi-massive Ni-PGE sulphide
mineralisation, further validating the presence of semi massive to massive
sulphides associated with the chonolith and supporting the potential for a
large, continuous magmatic system that hosts massive nickel sulphide, targets
of which were identified in the recent airborne magnetic and gravity survey.

Highlights of results

Zone 2

·      2.27 m @ 0.27 % Ni, 0.17 % Cu, 2.27 g/t 3PGE+Au

*including 0.77 m @ 0.31 % Ni, 0.18 % Cu, 2.19 g/t 3PGE+Au (346.23 - 348.50 m;
Z031D1).

·      4.06 m @ 0.23 % Ni, 0.14 % Cu, 1.36 g/t 3PGE+Au (342.44 - 346.50
m; Z031D0)

*including 1.56 m @ 0.30 % Ni, 0.18 % Cu, 1.72 g/t 3PGE+Au.

Zone 3

·      1.03 m @ 0.60 % Ni, 0.14 % Cu, 0.57 g/t 3PGE+Au (330.97 - 332.00
m; Z031D0).

·      0.70 m @ 0.65 % Ni, 0.40 % Cu, 0.36 g/t 3PGE+Au within 2.73 m @
0.39 % Ni (338.53 - 341.26 m; Z031D0).

The mineralised zones remain open both along strike and at depth, and the
geological model proposes that further down-dip drilling may intersect
significantly higher-grade Ni-Cu-PGE mineralisation. This interpretation is
supported by analogous mineralisation styles and grades observed at
neighbouring world-class deposits, including Ivanhoe Mines' Platreef Project
and Valterra Platinum's Mogalakwena Mining Complex.

Of particular significance is the consistent intersection of semi-massive
sulphide mineralisation associated with Zone 3 in the central part of the
Uitloop body, where a potential chonolith structure may link the Uitloop I and
II bodies. This is an exciting development, as such a chonolith could host a
larger, more continuous sulphide accumulation due to its structural setting
and potential to channel enriched magmatic pulses during emplacement and
develop a Ni-PGE rich massive sulphide, as discussed in RNS dated 21 May 2025
and 3 June 2025

Ni-Cu-PGE mineralisation within Zone 2 beneath the Lower Uitloop body. The
central portion of the section highlights consistent intersections of
semi-massive Ni-PGE mineralisation. Notably, historical boreholes Z03 and Z017
were terminated prematurely, before intersecting the full extent of the
Ni-Cu-PGE mineralised package.

Photographs of the sulphide mineralisation are shown in Figure 4, which
demonstrates that the mineralising systems are working in line with the
geological model and that the area holds significant potential for further
Ni-Cu-PGE mineralisation.

John Zorbas, CEO, commented:

"These results validate our geological model and confirm that Zeb Nickel has
the scale and grade to become a significant critical-metal asset. With
mineralisation open in multiple directions, and several exciting targets
identified from the recent airborne magnetic and gravity survey, we are as
excited as ever about the growth runway ahead and look forward to updating the
market on further exploration plans."
