Winston Tailings: Traxys Letter of Interest Signed

Panther Metals PLC (LSE: PALM), an exploration company focused on mineral projects in Canada, is pleased to announce that it has signed a letter of interest (“LOI”) with Traxys Europe SA, a division of Traxys Group (“Traxys”), a global commodity trading and marketing market leader.

The non-binding LOI concerns Panther’s Winston Tailings Project and is a formal recognition of an ongoing engagement between both parties as Panther progresses work to declare a Mineral Resource estimate, as part of series of ongoing workstreams to quantify, evaluate and permit the contained high-grade gold (Au), gallium (Ga), silver (Ag), zinc (Zn), copper (Cu), indium (In) and cobalt (Co) and other recoverable minerals located within the historic Winston Lake Mine tailings storage facility near Schrieber, Ontario, Canada.

Obonga Project – Advancing a High-Impact VMS and Critical Minerals District

Panther Metals’ Obonga Project in Ontario continues to demonstrate strong potential as a district-scale exploration opportunity targeting base and critical minerals. Since acquiring the Obonga Greenstone Belt in July 2021, the Company has advanced multiple high-priority targets including Wishbone, Awkward, Survey, Ottertooth, and Silver Rim.

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.

High-resolution magnetic and electromagnetic surveys continue to refine drill targeting across Obonga. Survey and Ottertooth remain highly prospective, hosting multiple untested geophysical anomalies and historic massive sulphide intercepts.

Winston Project – Tailings Evaluation and MRE Pathway

Panther Metals’ Winston Project represents a near-term, development-focused opportunity centred on the evaluation of historic mine tailings and has been the subject of prior technical and commercial assessment involving Extrakt.

Current work is focused on tailings sampling, metallurgical testing, and data validation to define metal content, recoverability, and support the preparation of a Mineral Resource Estimate (MRE). This approach provides a clear value-creation pathway with lower geological risk than greenfield exploration and aligns with modern reprocessing and critical mineral’s themes.

Dotted Lake Project – Hemlo-Adjacent Polymetallic Opportunity

Panther Metals’ Dotted Lake Project, acquired in July 2020, is located approximately 16km from Barrick Gold’s Hemlo Mine, within a well-established mining region.

Early exploration identified multiple gold and base metal anomalies, with initial drilling confirming gold mineralisation. In early 2025, follow-up drilling materially advanced the project, confirming nickel and magnesium mineralisation within an ultramafic intrusion and identifying a VMS-style system, significantly expanding the project’s polymetallic potential.

The program refined structural controls, extended mineralisation, and identified multiple new drill targets, positioning Dotted Lake as a high-upside, multi-commodity exploration asset.

Commercial Strategy – Focused Value Creation

Panther Metals is focused on disciplined, discovery-driven value creation through efficient capital deployment and technical execution. With Obonga delivering high-impact exploration, Winston providing a resource-focused development pathway, and Dotted Lake offering polymetallic upside, the Company maintains a balanced portfolio aligned with favourable commodity market conditions.

The Company’s strategy is to advance high-quality assets along the most efficient technical pathway, delivering tangible milestones that underpin long-term shareholder value.
