An exploration story that has changed method

ZEB Nickel Corp. (TSXV:ZBNI) is drawing attention because its work has moved from drilling and airborne surveying towards detailed ground-based geophysics, a sequence that usually precedes a new round of drilling. The company's shares trade on the TSX Venture Exchange as ZBNI, with a secondary Quotation on the OTCQB as ZBNIF.

The most recent development found is a release dated 15 April 2026, which said line preparation was complete at both priority survey areas and that a ground gravity survey had begun that day.

The Zeb Nickel Project

ZEB is based in Vancouver and holds the Zeb Nickel Project in Limpopo Province, South Africa, within the Bushveld Complex. It describes the asset as a developing Class 1 nickel sulphide project. It also states an interest in battery-related metals including graphite, lithium, cobalt, manganese, copper and aluminium.

The company's stated aim is a higher-grade maiden mineral resource compliant with National Instrument 43-101. That is an objective, not an existing estimate.

What the 2025 drilling showed

On 11 July 2025 the company reported assays from two vertical holes, Z031 and Z033, drilled with NQ core. It uses a model of four stacked zones: a near-surface bulk-tonnage nickel unit, a deeper zone containing nickel, copper and platinum-group elements, a feeder-style ultramafic body, and a gold-bearing zone.

Reported intervals were downhole lengths, not true widths. In the deeper Zone 2, one intersection returned 2.27 metres at 0.27% nickel, 0.17% copper and 2.27 grams per tonne of platinum, palladium, rhodium and gold combined. In Zone 3, 1.03 metres graded 0.60% nickel. A semi-massive sulphide sample assayed 1.00% nickel over 0.56 metres.

The company said mineralisation remains open along strike and at depth, and that further down-dip drilling may intersect higher-grade material. Additional drilling is needed to establish true thickness.

Airborne electromagnetic survey and the 2026 follow-up

In July 2025 ZEB completed an airborne electromagnetic survey using Spectrem's SpectremPlus system, flying about 736 line-kilometres at 150-metre spacing. The system can image conductive bodies at depths beyond 700 metres, which matters because sulphide mineralisation tends to conduct electricity.

The release promised processed data, three-dimensional inversion models and an integrated interpretation, with a drill-target inventory expected near the end of the third quarter of 2025. The April 2026 ground surveys are intended to refine anomalies from that airborne work and help rank targets for the next drilling campaign. An electromagnetic survey of the frequency-domain type was due shortly after the gravity work began.

Analysis and risks

The logic is conventional: broad airborne data narrows the search, ground surveys sharpen it, and drilling tests it. The sequence reduces wasted metres, but it does not guarantee that anomalies will prove to be economic mineralisation.

The drill grades reported so far are modest, and intersections of one to four metres do not yet define a deposit. Investors should note that the company, like most explorers, relies on Equity markets for funding. Its interim financial statements for the period to 31 December 2024 were filed on 3 March 2025, but the release itself contained no figures.

Other risks include South African regulatory and operating conditions, Commodity price swings in nickel, and the usual uncertainty around technical interpretation.

What to watch next

The milestones to follow are results from the gravity and electromagnetic surveys, a published drill-target list, the start of the planned drilling campaign, and any move towards the maiden resource estimate. Updated financial statements and the company's cash position will show how far current funding stretches.

Investors should treat each release as incremental evidence.
