Winshear Portsoy Project – Downhole Electromagnetic Survey Outlines Strong Conductor in the South Zone Close to Recent Drilling

Article content

VANCOUVER, British Columbia, July 15, 2026 (GLOBE NEWSWIRE) — Winshear Metals Corp. (TSX-V: WINS, FRA: 9HR0) reports that a downhole electromagnetic (‘DHEM’) survey completed after the recent drill program at the Portsoy Nickel – Copper – Cobalt (Ni-Cu-Co) Project in northeast Scotland, has identified a strong conductor, with characteristics of a massive sulphide body. The strong conductor is close to the 460m long drill hole RBD030 at the South Zone of the Rodburn Target (see Company news release dated May 26, 2026).

Caution Regarding Forward Looking Statements

Article content

Certain of the statements made and information contained in this press release may constitute forward-looking information and forward-looking statements (collectively, “forward-looking statements”) within the meaning of applicable securities laws, including statements regarding the downhole electromagnetic survey conducted at the Portsoy Project, the size, orientation, location and conductivity of the modelled conductor, the potential association of the conductor with massive sulphide mineralization, and the timing, scope, completion and results of the 2026 field program. The forward-looking statements in this press release reflect the current expectations, assumptions or beliefs of the Company based upon information currently available to the Company. With respect to forward-looking statements contained in this press release, assumptions have been made regarding, among other things, the reliability of information prepared and/or published by third parties that are referenced in this press release or was otherwise relied upon by the Company in preparing this press release. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and no assurance can be given that these expectations will prove to be correct as actual results or developments may differ materially from those projected in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include but are not limited to: uncertainty in the interpretation and modelling of DHEM conductors; the possibility that conductors may not be associated with economic nickel, copper or cobalt mineralization; the risk that future drilling may not intersect massive sulphide mineralization or mineralization comparable to historical results; uncertainty regarding continuity, grade, true thickness and extent of mineralization; delays or challenges in planning, permitting, financing or completing exploration; access, weather, logistical, contractor and community-related risks in Scotland; changes in commodity prices, exchange rates, capital markets, laws or government policy; risks inherent in early-stage mineral exploration; and the other risks described in the Company’s public disclosure record. Readers are cautioned not to place undue reliance on forward-looking statements due to the inherent uncertainty thereof. Such statements relate to future events and expectations and, as such, involve known and unknown risks and uncertainties. The forward-looking statements contained in this press release are made as of the date of this press release and except as may otherwise be required pursuant to applicable laws, the Company does not assume any obligation to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise.
