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. has provided an update for the company's flagship Kenbridge nickel-copper-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 2,100 metres of drilling has been completed to date. The first three drill targets have been completed. Samples have been delivered to AGAT Labs in Calgary for analysis. The drill rig is currently drilling the fourth 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. Zone A was intersected from 493.0 m to 503.7 m drill depth and returned 1.58 per cent Ni, 0.79 per cent Cu over 10.7 metres including 5.0 metres of 3.02 per cent Ni, 1.48 per cent Cu. Zone B was intersected from 532.4 m to 541.5 m drill depth. Results were 0.58 per cent Ni, 0.20 per cent Cu over 9.1 metres including 1.2 metres of 2.04 per cent Ni, 0.38 per cent Cu.

Tartisan chief executive officer Mark Appleby states, "The phase 1 2026 drill program is well under way and will test targets to upgrade inferred resources into the measured and indicated categories as well as look to expand the deposit down dip of the existing resource."

The Kenbridge property is in the Kenora mining district, Sioux Narrows, Ont., Canada, with all-season road access. The Kenbridge deposit has an existing shaft to a depth of 2,042 feet (622 metres), with level stations at 150 feet (45 m) intervals below the shaft collar and two levels developed at 350 ft (107 m) and 500 ft (152 m) below the shaft collar.
