(MENAFN- Newsfile Corp) Toronto, Ontario--(Newsfile Corp. - December 1, 2025) - Tartisan Nickel Corp. (CSE: TN) (OTCQB: TTSRF) (FSE: 8TA) ("Tartisan", or the "Company") is pleased to announce that it has completed the purchase of three claims historically identified as the "Apex Claims" located in the Atikwa Lake region, in the Kenora Mining District, Northwestern Ontario.

The acquisition totals approximately 420 hectares and consolidates a highly prospective land position contiguous to and immediately south of Tartisan's flagship Kenbridge Nickel-Copper-Cobalt Project, situated in the Kenora Mining District. The total Kenbridge Project land package now encompasses approximately 4,724 hectares, or roughly 47 square kilometres.

The Apex Claims are underlain by Archean-aged volcanic and intrusive rocks that are known to host nickel, copper, cobalt, and gold mineralization in the region. Historical geoscience data associated with the tenure block includes surface sampling, prospecting, and airborne geophysics, indicating favourable structures and lithologies for magmatic Ni-Cu-Co sulfide mineralization.

This land package provides Tartisan with:

• Expanded regional exploration coverage contiguous to the Kenbridge Project.

• Potential for parallel nickel-copper feeder systems and structural repeats like Kenbridge.

• Strategic control of an under-explored but historically identified MDI-level prospect area with 13 historical diamond drill holes.

• Additional opportunities for resource discovery, enhancing the long-term development profile of the Kenbridge district.

Next Steps:

Tartisan's technical team will integrate all available historical data from the Apex Claims into the Company's regional geological model. Initial work in 2025-26 is expected to include:

• Compilation of historical assessment files

• Review of airborne magnetic and EM datasets

• Prospecting and surface sampling

• Target generation for potential future drill testing

Mark Appleby, President & CEO, stated: "The Apex Claims enhance our nickel-copper focused footprint in the Kenora Mining District and complements our ongoing work at Kenbridge. These highly prospective ground positions provide Tartisan with additional exploration pathways and district-scale upside at a time when demand for critical minerals continues to grow."
