URU Metals Limited

("URU" or the "Company")

 

Zeb Nickel Project to commission a SpectremPlus™ EM Survey to Build on 2025
High-Resolution Gravity-Magnetic Dataset

URU Metals Limited ("URU" or the "Company") is pleased to announce that it has
engaged Spectrem Air Proprietary Ltd. ("Spectrem") to conduct an approximately
736 line-kilometre SpectremPlus™ airborne time domain electromagnetic
("AEM") survey over the Company's flagship Zeb Nickel Project, located in
Limpopo Province, South Africa.

Background

In early 2025 URU completed a re-interpretation of high-resolution fixed-wing
gravity and magnetic data. The new inversion models confirmed an ultramafic
feeder between the Uitloop I and Uitloop II ultramafic bodies and delineated
several NE-SW structural corridors interpreted as magma conduits. Coincident
gravity-magnetic highs flanking these structures are considered potential
sulphide trap sites. The AEM survey will induce a current in any conductive
bodies in the ground and measures their response, thus locating any buried
massive nickel sulphide ore bodies.

The SpectremPlus™ system delivers one of the highest transmitter moments in
commercial AEM, enabling imaging of conductive bodies to depths of exceeding
700 m, however the depth of investigation is model-dependent and may vary
according to local geology, conductivity and noise conditions. By
discriminating between highly conductive massive or semi-massive sulphides and
resistive host rocks, the survey will complement the existing gravity-magnetic
model and sharpen drill-target definition.

A summary of the expected benefit of the SpectremPlus

                                                                                                                                                             sharpening 3-D drill targeting

 

By integrating the EM conductivity voxels with the existing gravity and
magnetic models, the technical team expects to generate a prioritised pipeline
of drill-ready targets for potential semi-massive to massive nickel-sulphide
mineralisation associated with Zones 2 and 3.

 

Richard Montjoie, VP Exploration, commented:

"Previous gravity and magnetic surveys defined the geological architecture and
identified dense ultramafic targets across the project area. The
SpectremPlus™ system will now allow us to pinpoint which of these targets
are conductive, an important indicator of potential sulphide mineralisation.
By integrating these datasets, we're significantly improving our ability to
target high-priority drill locations, thereby increasing the likelihood of a
semi-massive to massive Ni-Cu-PGE sulphide discovery."

 

Survey specifications

The airborne survey will cover approximately 736 line-kilometres, flown using
150 m spaced traverse lines (azimuth 120°) and 1,500 m tie-lines (azimuth
30°). The programme will utilise Spectrem's converted DC-3 turboprop
aircraft, equipped with the proprietary SpectremPlus™ AEM system, which
delivers an exceptional RMS dipole moment of 756 kA·m² enabling imaging of
conductive bodies at depths exceeding 700 metres. Data acquisition is
scheduled for July 2025, with flying expected to be completed within three
days, weather permitting. Final processed data and interpretations are
expected within 30 days of survey completion.

Spectrem will provide a comprehensive dataset to support advanced targeting,
including:

·    Levelled X-, Y-, and Z-component EM data with conductivity depth
images ("CDIs")

·    1D inversion profiles and a 3D conductivity voxel model

·    Late-time EM anomaly picks with prioritised target recommendations

·    Total Magnetic Intensity ("TMI") grid and a high-resolution digital
elevation model ("DEM")

These deliverables will be critical in refining drill targeting and de-risking
future exploration campaigns.

Next Steps Toward Drilling

Once the EM data has been delivered, Zeb's technical team will:

• Integrate geological, gravity, magnetic, and EM datasets into a unified 3D
geophysical block model.

• Identify and rank high-priority target zones where conductivity, density,
and magnetic susceptibility signatures align, which are hallmarks of potential
massive sulphide accumulations.

• Design drill programs to optimally test these targets, including modelling
drill hole orientation and depth.

 

Safety & Environmental Assurance

The SpectremPlus™ survey will be flown under the International Airborne
Geophysics Safety Association (IAGSA) framework and audited to BARS aviation
standards, with a job-specific risk assessment completed before mobilisation.
Flights will maintain ~90 m ground clearance within conservative speed and
bank-angle limits and are continuously satellite-tracked for real-time
oversight. Spectrem's field protocols minimise disturbance and the
non-ionising EM field is proven harmless to wildlife and groundwater.
