Tartisan Nickel Corp. Completes Airborne MobileMTm and Borehole Em (BHEM) Geophysical Surveys at the Kenbridge Nickel-Copper-Cobalt Project, Northwestern Ontario; Interpretation Underway

Toronto, Ontario--(Newsfile Corp. - July 9, 2026) - Tartisan Nickel Corp. (CSE: TN) (OTCQX: TTSRF) (FSE: 8TA) ("Tartisan", or the "Company") is pleased to announce the successful completion of an airborne MobileMTm geophysical survey and the Borehole Electromagnetic (BHEM) survey at its flagship Kenbridge Nickel-Copper-Cobalt Project, located near Sioux Narrows in the Kenora Mining District of Northwestern Ontario.

The airborne MobileMTm survey was designed to provide a detailed understanding of the geological architecture across the approximately 47 square kilometer Kenbridge property and identify potential conductive features associated with nickel-copper sulphide mineralization.

The Borehole EM survey was completed on selected drill holes from the recently completed Kenbridge drill program to investigate off-hole conductive responses that may represent extensions of known mineralization or previously unidentified sulphide targets.

Interpretation of the geophysical datasets is now underway by the Company's technical consultants.

The integration of the MobileMTm and BHEM results with existing geological, geochemical and drilling data is expected to assist in refining exploration targets and guiding future drilling programs.

Mark Appleby, President and CEO of Tartisan Nickel Corp., commented: "The completion of these advanced geophysical surveys represents another important milestone in the systematic advancement of the Kenbridge Project. MobileMTm and Borehole EM are powerful exploration tools that have the potential to identify new conductive targets and improve our understanding of the mineralized system. We look forward to receiving the final interpretations and incorporating those results into our exploration strategy."

The Company expects to provide a further update once the interpretation has been completed and the technical team has finalized its recommendations.
