Tartisan Nickel acquires nickel-copper claims at Turtle Pond

Toronto, Ontario--(Newsfile Corp. - June 23, 2026) - Tartisan Nickel Corp. (CSE: TN) (OTCQX: TTSRF) (FSE: 8TA) ("Tartisan", or the "Company") is pleased to announce that the Company has acquired four additional claims in the Turtle Pond Area, Northwestern Ontario, approximately 40 km south of Dryden, Ontario. The property size now consists of 170 staked units covering 3,564 ha. which is wholly owned by Tartisan Nickel Corp. The claims are located approximately 70 kms east of the Company's flagship Kenbridge Nickel-Copper Deposit. The property is situated in an area of excellent infrastructure and consists of 170 claim units and hosts the historical Glatz, Double E and Night Danger nickel-copper showings.

Previous exploration efforts identified nickel-copper sulphide mineralization in twelve trenches along a 700 metre trend at the Glatz nickel copper showing. The zone, discovered in 1965 by local prospector A. Glatz, is up to 40 metres wide and is open along strike and at depth. Historical grab samples were reported to contain up to 1.95% Ni.

In 2007, Canadian Arrow Mines Limited, conducted a surface grab sampling program which produced the following results: 1.28% Ni, 0.26% Cu re Glatz Trench 2; 0.99% Ni, 0.18% Cu re Glatz Trench 3; 0.39% Ni, 4.06% Cu re Trench 4. The mineralization varies from disseminated sulphides to narrow semi-massive sulphide bands. Six short drill holes were completed at that time with hole GZ-09- 02 encountering 0.34% Ni, 0.16% Cu and 0.02% Co over 5.9 m from 45.0-50.9 m.

A nickel-copper-PGE discovery on the Double E airborne VTEM anomaly was identified in 2008. The drilling intersected two separate upper and lower mineralized zones in 2 drill holes. Hole EE-09-02 intersected 4.2 metres of 0.81% Ni, 0.52% Cu, 0.20gpt Pt, 0.16gpt P and 0.20gpt Au at a depth of 25.5 metres.

This included 2 metres of 1.35% Ni, 0.81% Cu, 0.36gpt Pt, 0.27gpt Pd and 0.31gpt Au. A second zone was intersected at a depth of 135.1 metres containing 8.2m of 0.55% Ni and 0.38% Cu. Hole EE-l0-04 intersected 1.9 metres of 0.51% Ni, 0.24% Cu at a depth of 21.4 metres and a second narrow intersection of 1.9 metres of 0.52% Ni, 0.28% Cu at a depth of 28 metres.

Exploration diamond drilling work completed in 2009 and 2010 on the Night Danger nickel-copper intercepts and reported a nine-metre-wide section of stringers and blebs of sulphide which assayed 0.57% Ni and 0.45% Cu at a drill depth of 79m in hole ND-09-1. Two sections within this interval assayed greater than 1% nickel. Drill hole ND-10-1 intersected 4.53% Ni over 0.7m at a drill depth of 57.5m (Source; MNDM assessment files and Canadian Arrow Mines Limited news release dated June 1, 2010, SEDAR).

From November 28 th to December 21 st , 2024, a TDEM Geophysical survey was performed on the Turtle Pond Lake Property and was undertaken by Expert Geophysics Limited. Tartisan Nickel Corp. requested this survey for the purpose of determining drill targets and potential future exploration work on The Property. Mark Appleby, President and CEO of Tartisan stated: "The Glatz, Double E and Night Danger nickel-copper showings display similar nickel and copper tenors as what we find near surface at our Kenbridge Nickel-Copper Deposit.

Acquisition of these claims will complement the company's larger objective of developing the Kenbridge Project into an area play. The Company has formulated a 2026 Turtle Pond exploration program consisting of trail and access work, geological mapping and surface sampling, with potentially diamond drilling in 2026-27. We will have boots on the ground this summer."
