High-power AEM Interpretation Highlights
Vancouver, BC, September, 2025, – ZEB Nickel Corp. (ZBNI:TSX-V) (OTC:ZBNIF) (“Zeb”
or the “Company”)
ZEB Nickel Corp (“ZEB” or the “Company”) is pleased to report positive results from the
independent interpretation of its high-power SpectremPlus™ airb orne electromagnetic
(“AEM”) survey over the Zeb Nickel Project, Limpopo, South Afri ca. The AEM dataset
h a s b e e n i n t e g r a t e d w i t h t h e p r o j e c t ’ s g r a v i t y a n d m a g n e t i c m o dels to refine the
g e o l o g i c a l f r a m e w o r k a n d r a n k c o n d u c t i v e a n o m a l i e s a l o n g t h e u ltramafic intrusive
trend.
Highlights
Coherent conductive responses identified: The interpretation delineates multiple
discrete, laterally persistent conductors after screening for c ultural and
stratigraphic effects, with several features coincident with ma gnetic trends and
intrusive margins which is consistent with the Company’s chonol ith/feeder-style
nickel sulphide model.
3-D integration strengthens the geological case: Combining AEM, gravity and
magnetics supports a focused corri dor where sulphide accumulati on is
considered most plausible within or adjacent to the ultramafic package.
De-risking pathway defined: The Company is advancing a follow-up programme
that will include ground-based electromagnetic methods, downhol e EM and
complementary techniques to refine geometry, depth and conducta nce prior to
selecting locations for initial drill-testing.
The interpretation of the recently completed Spectrem survey by Geofocus (Pty) Ltd
outlines several clear, late-time conductive zones that cluster along the edges of the
ultramafic body, interpreted to be a chonolith, and in close pr oximity to the magnetic
a n d g r a v i t y s h e l l s . T h i s s p a t i a l p a t t e r n i s e x a c t l y w h a t o u r c honolith/feeder model
anticipates: nickel-copper-PGE sulphides commonly accumulate in ‘trap’ sites along basal
contacts and feeder embayments, often slightly offset from the densest and most
magnetic core of the intrusion. By integrating the EM with magn etics and gravity in 3-
D, we’ve narrowed targeting to a well-defined corridor where intrusion-related sulphide
mineralisation is geologically plausible, while filtering out many responses more likely to
reflect stratigraphy or surface effects. These results do not c onfirm mineralisation, but
the alignment of independent datasets materially strengthens th e technical case and
provides a strong foundation for focused follow-up geophysics t o refine geometry and
prioritise drill-ready targets. The main conductor picks are presented in Figure 1 below.

intrusion or in feeder embayments, slightly offset from the har dest, most magnetic core. This
geometry is consistent with that setting, although it does not confirm mineralisation.
Next Steps
To increase precision ahead of any drill selection, the Company will conduct a ground-
based geophysical survey over selected targets. The work may include a combination of
moving-loop and/or fixed-loop EM and limited complementary meth ods where
appropriate.
G r o u n d - b a s e d s u r v e y s p r o v i d e o r i e n t a t i o n - c o n t r o l l e d , h i g h e r s i gnal-to-noise
measurements that enable constrained plate modelling of conduct ive bodies. This
improves confidence in position, dip and strike, and helps disc riminate compact, highly
conducting sulphide targets from look-alikes such as banded iro n formation, graphitic
horizons, conductive weathering fronts or cultural coupling. In practical terms, follow-
up geophysics reduces false positives, sharpens drill vectors a nd lowers the probability
of unnecessary metres, thereby improving capital efficiency and technical outcomes.
The completion of the AEM survey combined with the ground based geophysical work

di sc o very. The Com pany are wo rking c lo se ly wit h the Mini ng department in country
regarding the awarding of the Mining Rights and hope to be in a position to update
shareholders soon. Upon successful awarding of the Mining Rights, the Company intends
on embarking on an extensive drill programme to further prove up the deposit.

The Company is finalising the scope and sequencing of the follo w-up programme and
the Company will provide a further update once the programme se lection, scheduling
and access arrangements are complete.
Richard Montjoie, VP Exploration, commented:
"We’re encouraged that the Spectr em results further support our intrusion-hosted
chonolith/feeder model at Zeb. The conductive zones cluster alo ng intrusive margins
and align with magnetic and gravity shells, which is consistent with where our model
anticipates potential sulphide t raps. Our next step is to apply targeted ground
geophysics to refine geometry and conductance, reduce false positives, and position any
initial drill holes with greater confidence."
Highlights
Survey completed safely and on budget.
~736 line‑kilometres flown at 150 m traverse spacing using Spec trem’s
converted DC‑3 turboprop platform equipped with the proprietary
SpectremPlus™ system, capable of imaging conductive bodies to d epths
in excess of 700 m.
Final, fully processed datasets, 3‑D inversion models and an in tegrated
geophysical interpretation are expected in the near term.
Deliverables will be integrated with existing gravity‑magnetic data to
refine and prioritise drill targets focused on potential high‑g rade
nickel‑sulphide mineralisation.
Next Steps
The Spectrem Air team has begun final processing, following whi c h t h e C o m p a n y ’ s
geophysical consultant will comp l e t e a f u l l i n t e r p r e t a t i o n a n d integration with the
recently acquired gravity and ma gnetic datasets. Geofocus has b een tasked with the
integration of the geological, g ravity, magnetic, and EM datase ts into a unified 3D
geophysical block model. Management anticipates releasing the r esults, together with
an updated technical program and drill‑target inventory, shortly after receipt of the final
deliverables, which are expected near the end of Q3 2025.
Richard Montjoie, VP of Exploration, commented:
"Completion of this state‑of‑the‑art AEM survey marks another ke y milestone for the
Zeb Project. The high‑resolution data will underpin our next phase of exploration as we
advance toward testing high‑grad e nickel sulphide targets, whic h, if successful, will
significantly move the needle on the Project."
