TARTISAN NICKEL CORP. PROPOSES INITIAL 5,000 METRES OF PHASE 2 DRILLING TO EXPAND THE KENBRIDGE MINERAL RESOURCE ESTIMATE, NORTHWESTERN ONTARIO

Tartisan Nickel Corp. has proposed a phase 2 diamond drilling program at its Kenbridge nickel-copper-cobalt project near Sioux Narrows in the Kenora mining district of Northwestern Ontario. The program initially contemplates approximately 5,000 metres of drilling to expand the existing mineral resource estimate by testing the downdip continuation of the deposit and a modelled borehole electromagnetic plate 209.

The proposed phase 2 program comprises initially four diamond drill holes. Three planned holes, P1 to P3, would test the projected continuation of the mineralized zone at depth. A fourth hole, P4, would test the modelled BHEM plate 209.

The four holes outlined total approximately an initial 4,850 metres of drilling. Final hole selection, sequencing and orientations may be adjusted as drilling progresses.

Testing for mineralization at depth

Holes P1 to P3 are designed to test for nickel-copper-cobalt mineralization downdip beyond the currently defined deposit.

Drilling results would provide data to support an updated mineral resource estimate. Any increase in the mineral resource estimate will depend on the results and subsequent geological modelling and resource estimation.

Hole paths and geological projections are interpretive and may be revised.

Proposed hole P4 would test the source of modelled BHEM plate 209. The BHEM response is an exploration target and does not, by itself, establish mineralization or a mineral resource.

Mark Appleby, president and chief executive officer of Tartisan, commented: "Our 2026 phase 2 drill program is focused on expanding the Kenbridge mineral resource estimate by testing the deposit at depth and evaluating modelled BHEM plate 209. These targets give us the opportunity to assess both the continuation of known mineralization and the potential for additional mineralization beyond the currently defined deposit. With BHEM interpretation, site and roadwork completed over the summer, and drill pads in place, we have advanced preparations for this next stage of drilling. We are looking forward to phase 2."

Project access and preparation

Kenbridge is located approximately 70 kilometres southeast of Kenora near Sioux Narrows in Northwestern Ontario. The property is accessible from Hwy. 71 through approximately 25 kilometres of all-season road east to the Kenbridge access-road junction, followed by approximately nine kilometres along the property access road to the core facility. The property access road accommodates four-wheel-drive vehicles, and the bridge near the southern end of the property accommodates heavy machinery.

Significant work on the site and road was completed over the summer months to support phase 2 drilling. Drill pads are in place along with on-site core-handling facilities supporting the proposed program. NQ or equivalent core size is contemplated. Mobilization timing and the final program scope remain to be confirmed.

Qualified person

Dean MacEachern, PGeo, an independent consultant to the company, is the qualified person for the Kenbridge project as defined by National Instrument 43-101.
