Winshear Portsoy Project – Successful Metallurgical Testwork Produces Marketable Copper and Highly Attractive Nickel Concentrates
WINSHEAR PORTSOY PROJECT – SUCCESSFUL METALLURGICAL TESTWORK PRODUCES
MARKETABLE COPPER AND HIGHLY ATTRACTIVE NICKEL CONCENTRATES
Vancouver, July 27, 2026
Winshear Metals Corp. (TSX-V: WINS, FRA: 9HR0) reports positive results from the first ever
metallurgical testwork conducted on the nickel – copper – cobalt mineralization from the
Rodburn Target, Portsoy Project, NE Scotland.
The testwork was conducted by Blue Coast Research Ltd of British Columbia, Canada, under the
supervision of Rob Thorpe (VP Innovation and Technology) and Tony Tran, P.Eng. (Project
Metallurgist).
Highlights
• Metallurgical studies were conducted on a composite sample of massive to disseminated
sulphide mineralisation from drill holes completed in 2023 / 2024.
• The objective was to determine the amenability of the mineralisation to respond to
conventional sequential flotation methods and produce marketable copper and nickel
concentrates.
• Head assays were 0.82% copper, 1.64% nickel (1.38% nickel in sulphide), and 0.11%
cobalt.
• Based on the batch tests, copper recoveries of 75-80% and nickel of 60-65% can be
expected. Further testwork, including locked-cycle studies (LCT), is anticipated to improve
recoveries.
• Nickel concentrate grades of 14-16% were produced and included in excess of 1% cobalt.
Such a concentrate would be considered ‘highly attractive to nickel smelters’ (Blue
Coast).
• The nickel concentrate contained 0.54% copper which would be payable.
• Copper concentrate grades of ~25% with <1% nickel content are considered typical of
this style of mineralisation. The low nickel content falls below the penalty charge levels.
Richard Williams, CEO of Winshear, commented; “These are very positive results at this stage of
the Portsoy Project. It was key for us to understand the metallurgical characteristics of the
mineralisation and to ensure the recoverability of the copper, nickel and cobalt and the quality of
the concentrates produced at an early stage.
“The results provide confidence that the Rodburn mineralisation can be processed using
conventional methods, with the potential to produce saleable copper and nickel concentrates,
supporting the case for further optimisation testwork as the project advances.”

applicable securities laws, including statements regarding the metallurgical studies conducted at the Portsoy Project,
the ability to continue to meet the metallurgical recoveries presented in this new release, 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

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: variability of the style of sulphide mineralisation; 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
