High-Grade Mineralization Extended Downdip at the South Zone and Westwards at the North Zone

Winshear Metals Corp.  (TSX-V: WINS) (FRA: 9HR0) reports very encouraging drill results from the recently completed drill program conducted at the Rodburn Target, Portsoy Project, NE Scotland, substantially expanding the footprint of high-grade mineralization.

Highlights

South Zone

• Drilling extended high-grade mineralisation 100 meters down-dip from earlier high-grade intercepts (see Table 1 and Figure 1 below), returning 8.15m grading 0.77% nickel, 1.14% copper, and 0.05% cobalt, including 6.0m grading 0.98% Ni, 1.51% Cu and 0.06% Co in drill hole RBD029;
• Drill hole RBD030 intersected 4m grading 0.29% Ni and 0.18% Cu a further 100m downdip from RB029. This intercept is interpreted to represent the mineralized halo peripheral to the massive sulphide mineralization (refer to the next bullet point);
• Downhole electromagnetic (DHEM) surveying conducted in RBD030 detected a strong conductor, with characteristics of massive sulphide mineralization, 100m east of RBD030 – this is untested to date.
• See Figure 1 and Figure 2 for the locations of the drill intercepts relative to the position of the DHEM target.

North Zone

• Drilling at the North Zone (RBD028) extended mineralization 100m to the west of RBD015 (9m grading 0.61% Ni, 0.23% Cu, 0.03% Co) and RBD016 (9m grading 1.13% Ni, 0.73% Cu, 0.11% Co).
• RBD028 intersected two well mineralised zones:
  • 3m grading 0.98% Ni, 0.14% Cu, 0.045% Co, and
  • 4m grading 0.76% Ni, 0.32% Cu, 0.034% Co
  • Within a 16m thick zone grading 0.39% Ni, 0.14% Cu, 0.018% Co
• Figure 3 shows the growth of the North Zone to the west.

Richard Williams, CEO of Winshear, commented: “These drill results support our view that Rodburn is part of a well-mineralized nickel-copper-cobalt system. Further drilling will be required to continue expanding and defining the extent of mineralization, but the work completed this year has delivered against the key objectives we set for the program.

“We have successfully expanded the footprint of high-grade mineralization, demonstrated that downhole EM surveying can detect and help guide future drilling for massive sulphide mineralization, and confirmed that the mineralization responds well to conventional flotation processing, with the potential to produce marketable nickel and copper concentrates.

“These are important technical milestones for the Portsoy Project and provide a strong basis for the next phase of work. The Company plans to drill test the newly identified DHEM conductor at the South Zone in the next phase of drilling, alongside further step-out holes to continue expanding the North and South Zones.”

The 2026 Drill Program

The Company drilled a total of six diamond drill holes (1,235.6m), four testing the North Zone (524.5m) and two testing the South Zone (711.1m) – see news release dated May 26, 2026.

Table 1 below summarises the significant intersections from drilling at Rodburn to date, including drill holes from the 2023 / 2024 program. A complete table can be accessed from the 43-101 Technical Report here.

Intercept lengths are thought to be in the range of 85% to 100% of true thickness.

Sampling Methodology

Drill core is logged and mineralized intervals are marked for cutting in half along the core long axis by diamond saw. One half of the core is retained for reference purposes, and the other half sent for analysis.

The Company inserts QAQC samples at the rate of one standard every 20 samples, one blank and one duplicate every 25 samples. Drill core samples average ~2.5kg each and are securely bagged and transported by courier to the Bureau Veritas Commodities Canada Limited laboratory in Vancouver, Canada. At the lab, samples are prepared by crushing the whole sample, homogenising and then pulverising a 250 grams riffle-split to 80% -75 microns. Pulps are analysed by the AQ-252-EXT method using a 30g digestion and 53-element ICP. Any overlimit Ni-Cu-Co results are re-analysed using the AQ370 method.
