Panther Metals PLC (LSE: PALM), the exploration company focused on mineral projects in Canada, is very pleased to report the fifth batch ("Batch 5") of Vibracore sample assay results for the Winston Tailings Project near Schrieber, Ontario, Canada.
Key points:
- Fifth batch of tailings core sample assay results (Table 1) received for twenty seven Vibracore collar locations (WT-26-009, WT-26-010, WT-26-023, WT-26-025, WT-26-043, WT-26-053, WT-26-054, WT-26-061, WT-26-065, WT-26-070A, WT-26-071A, WT-26-072, WT-26-082, WT-26-083, WT-26-085, WT-26-093, WT-26-095, WT-26-098, WT-26-099, WT-26-100, WT-26-101, WT-26-102, WT-26-103A, WT-26-104, WT-26-105, WT-26-107& WT-26-108) situated upon sixteen east-west profiles (Figure 1).
- Assayed intersections reported for Batch 5 are taken from total tailings thicknesses varying between 1.5m to 15.2m (Table 2). The maximum vertical thickness of tailings (below ice and water) intersected across the TSF is 16.8m with an average vertical thickness of 8.7m.1
- Results continue to show good grade consistency across the vertical depth-profile and laterally between Vibracore hole collar locations, and support or exceed the 2025 preliminary assay results announced 31 July 2025 and the results announced 17 March 2026, 19 March 2026, 14 April 2026 and 28 April 2026. 2,3,4,5,6
Darren Hazelwood, Chief Executive Officer commented:
"These latest results continue to confirm continuity across the Winston Tailings Project footprint, strengthening our confidence in the project's scale, consistency and commercial potential.
Alongside Panther's accelerating business model, we believe the market is increasingly recognising the broader potential of tailings reprocessing, which can support the advancement of other high-impact projects across our portfolio.
Ongoing work continues to expand our understanding of the asset while reducing risk, and we look forward to updating shareholders as the project advances."

On 9 February 2026 Panther announced plans for an approximately 2,000-metre diamond drilling program at the Wishbone Prospect, following the grant of an Exploration Permit in June 2024 valid through 2027. Previous work confirmed compelling VMS-style mineralisation, including 27.3m of massive sulphide and 51m of sulphide-dominated mineralisation across multiple lenses, supported by high-grade copper anomalies in lake sediments.
In July 2024, Panther secured an Exploration Permit for Awkward West, enabling up to 31 drill holes. Historic drilling returned 27.2m at 2.25% TGC, with zones exceeding 5% TGC, alongside indications of nickel, copper, and platinum group elements, aligning with the Company's critical minerals strategy.
