Tartisan Nickel Corp. to Advance the Sill Lake Silver Project, Sault Ste. Marie, Ontario

Tartisan Nickel Corp. (CSE: TN) (OTCQB: TTSRF) (FSE: 8TA) ("Tartisan" or the "Company") is pleased to announce that the Company is advancing plans to move its 100% owned Sill Lake Silver Project, located approximately 30 km north of Sault Ste. Marie, Ontario, toward renewed exploration and project development.

The Sill Lake Project now 970 ha. in size is a former Silver-Lead producer with documented historic underground mining operations. The property hosts a historic mineral resource estimate prepared in accordance with NI43-101 standards by "*SMX International Corp., with an effective date of May 9, 2021, (SEDAR+)".

Historic NI43-101 Mineral Resource Estimate: *SMX International Corp.

At a 60-ppm silver cut-off, the NI43-101 report outlines the following in-situ Measured and Indicated Mineral Resources for the Main Vein:

• Measured Resources: 35,703 tonnes grading 4.52 oz/ton silver, containing 161,490 ounces of silver
• Indicated Resources: 67,941 tonnes grading 4.37 oz/ton silver, containing 296,843 ounces of silver
• Total Measured and Indicated Mineral Resources:103,644 tonnes grading 4.42 oz/ton silver, containing 458,333 ounces of silver

• With associated 1,467,965 pounds of lead and 505,126 pounds of zinc

In addition, there are three under-evaluated trends (North, Middle and South Trends) evident from drilling and surface sampling that may be significant for additional silver mineralization if furthered evaluated. In SMX International Corp's. NI43-101 report (2021) they reference Chemrox (2010) outlining a historic Inferred Silver Resource of approximately 660,000 ounces in these additional veins. The Company can not verify these estimates and view them as historical and for reference purposes only. The Company plans on evaluating these additional veins to assess their significance.

Project Advancement Strategy

Tartisan is undertaking technical and logistical planning to reactivate the Sill Lake Project, including:

• Compilation and review of historic drilling, sampling, and production data
• Evaluation of the North, Middle and South Trend Veins to assess their significance
• Identification of priority drill targets along the known mineralized trend
• Assessment of permitting, access, and infrastructure requirements
• Initial engagement with local and regional stakeholders

The Company views Sill Lake as a brownfields Silver-Lead opportunity within a proven Ontario mining jurisdiction, with the potential to generate meaningful exploration results through modern validation and drilling programs.

Tartisan will provide further updates as project and exploration activities advance.
