VANCOUVER, British Columbia, May 26, 2026 (GLOBE NEWSWIRE) -- Winshear Metals Corp. (TSX-V: WINS, FRA: 9HR) reports that it has completed the Phase 1 drill program at the Rodburn Target on the Portsoy Nickel – Copper – Cobalt project, located in Aberdeenshire, Scotland. Assays will be reported as soon as received.

The program comprised six drill holes for a total drilled length of 1,235.6m, with four holes drilled in the North Zone (524.5m) and two holes at the South Zone (711.1m).

The downhole electromagnetic (“EM”) survey conducted in RDB030 detected a strong off-hole conductor which will be tested in the next round of drilling.

North Zone Drilling

Four drill holes were completed at the near-surface North Zone bulk tonnage target to determine which direction the mineralization was trending. These four holes followed up the two 2024 drillholes which intersected:

33m grading 0.56% Ni equivalent* (see footnote below the table below for nickel equivalent calculations), including 9m grading 0.77% Ni equivalent in drillhole RBD015
59m grading 0.45% Ni equivalent, including 9m grading 1.65% Ni equivalent in drillhole RBD016
See Figure 1 cross section showing the 2024 drilling

The four 2026 drillholes (RBD025, RBD026, RBD027 and RBD028) were collared north, east and west of the 2024 drillholes (Figure 2). Disseminated sulphides were observed over a 69.5m section of RBD028, collared 60m west of RBD015 and RBD016, between a downhole depth of 18.1m to 87.6m. This is the widest zone of sulphide mineralization encountered to date on the project.

Observations from the drilling at the North Zone show the mineralization trends and thickens westwards and is still open. Further drilling is required to determine the extent of this zone.

South Zone Drilling

Two drillholes (RBD029 and RBD030), totaling 711.1m, were completed at the South Zone to test the downdip extension of the high-grade mineralization from the following 2023 / 2024 drillholes (see Table below for all significant intercepts and the relative nickel, copper and cobalt assays).

6.0m grading 2.8% Ni equivalent
12.0m grading 1.8% Ni equivalent
2.6m grading 0.9% Ni equivalent
5.4m grading 2.4% Ni equivalent

Drillhole RBD029 intersected the main sulphide mineralization between 218m and 226m downhole. This is substantially deeper than previously drilled and extends the main mineralized zone at least 80m down dip.

Drillhole RBD030 was drilled to a final depth of 460.8m and was designed to test for mineralization at depth and for use of downhole electromagnetic (“DHEM”) surveying to help detect off-hole massive sulphides to guide future exploration.

Disseminated sulphide mineralization was intersected between 430m and 450m – assays to be reported once received. The DHEM survey also indicates the presence of a nearby strong conductor to the east of the drill hole starting at ~300m downhole and extending to the end of hole depth. This represents a high-priority follow-up target and will be incorporated into the next phase of drilling.

The Rodburn Target

The Rodburn Target comprises five geochemical / geophysical anomalies, only two of which have been drill-tested recently – the North and South Zones in 2023 / 2024 by Peak Nickel Limited. Full details on the exploration results from the project can be found in a technical report entitled ‘NI 43-101 Technical Report for the Portsoy Nickel-Copper-Cobalt Exploration Project, Aberdeenshire, Scotland’, prepared under the supervision of independent Qualified Person Mr. Richard Siddle, MSc, MGeol, MAIG, Director and Principal Consultant of Addison Mining Services, UK, has been posted on the Company’s website and SEDAR+ page.
