NEWS RELEASE

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

i s a k e y s t e p f o r t h e C o m p a n y i n i d e n t i f y i n g t h e s e m i m a s s i v e - massive sulphide

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."
