Zeb Nickel Project to commission a SpectremPlus\u2122 EM Survey to Build on 2025 High-Resolution Gravity-Magnetic Dataset<\/strong><\/p>\n\n\n\n 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\u2122 airborne time domain electromagnetic (“AEM”) survey over the Company’s flagship Zeb Nickel Project, located in Limpopo Province, South Africa.<\/p>\n\n\n\n Background<\/strong><\/p>\n\n\n\n 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.<\/p>\n\n\n\n The SpectremPlus\u2122 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.<\/p>\n\n\n\n A summary of the expected benefit of the SpectremPlus<\/p>\n\n\n\n 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.<\/p>\n\n\n\n Richard Montjoie, VP Exploration<\/strong>, commented:<\/p>\n\n\n\n “Previous gravity and magnetic surveys defined the geological architecture and identified dense ultramafic targets across the project area. The SpectremPlus\u2122 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.”<\/em><\/p>\n\n\n\n Survey specifications<\/strong><\/p>\n\n\n\n The airborne survey will cover approximately 736 line-kilometres, flown using 150 m spaced traverse lines (azimuth 120\u00b0) and 1,500 m tie-lines (azimuth 30\u00b0). The programme will utilise Spectrem’s converted DC-3 turboprop aircraft, equipped with the proprietary SpectremPlus\u2122 AEM system, which delivers an exceptional RMS dipole moment of 756 kA\u00b7m\u00b2 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.<\/p>\n\n\n Figure 1: The specialised Spectrem aircraft that will carry out the SpectremPlus\u2122 airborne electromagnetic (AEM) survey over the Zeb Nickel Project area.<\/p>\n\n\n Figure 2: The map shows the Geophysical Airborne Survey Area.

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.<\/p>\n\n\n\n About the Company<\/strong><\/p>\n\n\n\n URU Metals is a mineral exploration and development company focused on advancing its high-potential critical metals projects in South Africa.
