Zeb Nickel Project to Commission a SpectremPlus(TM) EM Survey to Build on 2025 High-Resolution Gravity-Magnetic Dataset
Zeb Nickel Corp. (OTCQB: ZBNIF) has engaged Spectrem Air to conduct a 736 line-kilometre SpectremPlus™ airborne electromagnetic (AEM) survey at its flagship Zeb Nickel Project in South Africa's Limpopo Province. The survey follows the company's early 2025 high-resolution gravity-magnetic data reinterpretation, which confirmed an ultramafic feeder between Uitloop I and II bodies.
The SpectremPlus™ system, featuring a 756 kA·m² RMS dipole moment, can detect conductive bodies at depths exceeding 700 meters. The survey will be completed in July 2025, with final processed data expected within 30 days. The integrated data will help identify potential nickel-sulphide mineralization sites and optimize future drill targeting.

Vancouver, British Columbia--(Newsfile Corp. - July 17, 2025) - ZEB Nickel Corp. (TSXV: ZBNI) (OTCQB: ZBNIF) ("Zeb" or the "Company") is pleased to announce that the project 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 the project 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
| Existing dataset | New SpectremPlus™ EM | Integrated benefit |
| Gravity pinpoints dense ultramafic bodies and feeder conduits | EM discriminates highly conductive massive‐ to semi- massive sulphides from resistive country rock | Joint gravity-EM inversions isolate dense and conductive targets characteristic of Ni-Cu-PGE sulphides |
| Magnetics highlights magnetite-rich critical-zone horizons and fault offsets | EM traces the sulphide-rich horizons along strike and down-dip | Structural-lithological framework tied directly to sulphide conductivity, 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.
