Tartisan Nickel Corp. Intersects 10.7 Metres of 1.58% Ni, 0.79% Cu Including 5.0 Metres of 3.02% Ni, 1.48% Cu at the Kenbridge Nickel-Copper-Cobalt Project, Northwestern Ontario

Tartisan Nickel Corp. (CSE: TN,OTC:TTSRF) (OTCQB: TTSRF) (FSE: 8TA) (‘Tartisan’, or the ‘Company’) is pleased to provide an update for the Company’s flagship Kenbridge Nickel-Coppet-Cobalt Project located near Sioux Narrows, Northwestern Ontario. The drill program is designed to test the on strike and down dip potential for additional nickel sulphide mineralization to enhance the size and grade of the Kenbridge Deposit.

The drill rig was mobilized to the Kenbridge site in December 2025 and is currently operating. A total of 2,100m of drilling has been completed to date. The first 3 drill targets have been completed (drill holes KB26-207, KB26-208 and KB26-209 outlined on Figure 1). Samples have been delivered to AGAT Labs in Calgary for analysis. The drill rig is currently drilling the 4th drill hole KB26-210. This hole is designed to be drilled below the existing shaft bottom to test for the depth extension to the deposit.

Reported in this release are the results from the first infill drill hole KB26-207. Results from the hole confirm both A and B zones were intersected as outlined in the table below. Zone A was intersected from 493.0m to 503.7m drill depth and returned 1.58% Ni, 0.79% Cu over 10.7 metres including 5.0 metres of 3.02% Ni, 1.48% Cu. Zone B was intersected from 532.4m to 541.5m drill depth. Results were 0.58% Ni, 0.20% Cu over 9.1 metres including 1.2 metres of 2.04% Ni, 0.38% Cu.
