WINSHEAR PROVIDES UPDATE ON THUNDER BAY PROJECT,

PURCHASES ASSESSMENT CREDIT

Vancouver, June 23, 2026

Winshear Metals Corp. (TSX-V: WINS, FRA: 9HR0) (“Winshear” or the “Company”)

provides the following update on its field activities from the Thunder Bay Gold Project,

NW Ontario, as well as the purchase of an assessment credit valued at $608,000.

Thunder Bay 2026 Field Program

The Company has engaged Fladgate Exploration, a geological services company based

in Thunder Bay, to execute this summer’s field program, comprising soil sampling over

the Inflection, MacGregor, El Dorado and Kingfisher Targets, till sampling over newly

staked claims to the NE of the Kingfisher Target, and airborne magnetic surveys over

both Inflection and El Dorado (see Figure 1). Soil and till sampling is underway, and the

airborne magnetic survey commenced late last week. The summer field program is

expected to be completed by late July.

Based on the gold in till anomalies from the 2025 field program, the Company staked new

claims covering a 14km NE extension of the Kingfisher Target, which lies along the major

NE trending Kingfisher fault (Figure 1).

Purchase of Assessment Credit

The Company has entered in a purchase agreement to acquire certain mineral

exploration credits relating to claim 908950 which carries an exploration assessment

credit of $608,083. Subject to approval of the TSX-V, the Company will issue 1,000,000

shares and 500,000 warrants to the Vendors. The warrants allow the Vendors to purchase

500,000 shares in the Company at a price of $0.20 / share for a period of 3 years from

the approval date. The Vendors are the same group that the Company entered into

agreement with in 2025 (see Company News Release dated July 25, 2025 related to the

Thunder Bay Gold Project).

Figure 2 below shows the configuration of the Thunder Bay Project at this time.
