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 (https://urumetals.com/index.php/2025/06/03/zeb-nickel-project-3-d-geophysical-modelling/) and (https://urumetals.com/index.php/2025/05/21/zeb-nickel-identifies-high-priority-drill-targets/).

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.”
