Winston Tailings Mission: Mineral Useful resource Drilling

Panther Metals Plc (LSE: PALM), the exploration firm targeted on mineral initiatives in Canada, is happy to announce that Platinum Diamond Drilling Inc. (“Platinum”) has been contracted to undertake the Mineral Useful resource focussed drilling programme on the Winston Tailings Mission in Ontario, Canada.^{1, 2, 3}

The appointment of Platinum follows on from the appointment of SRK Exploration Ltd (“SRK EX”) as impartial consultants to conduct the Mineral Useful resource estimate (“MRE”).

The MRE will probably be considered one of a collection of workstreams to quantify, consider and allow the contained high-grade gold (Au), gallium (Ga), silver (Ag), zinc (Zn), copper (Cu) and cobalt (Co) and different recoverable minerals situated inside the historic Winston Lake Mine tailings storage facility (“TSF”).

Darren Hazelwood, Chief Govt Officer commented:

“The appointment of a drilling contractor for the Winston Tailings Mission marks a pivotal step ahead for the Firm. This programme is designed to validate the historic restoration manufacturing and produce a CIM compliant Mineral Useful resource estimate, a key milestone in taking the challenge by the restoration allowing course of.

The historic Winston Lake mine processing information signifies that the tailings have the potential to host commodities in portions important sufficient to basically remodel our enterprise.

Quantifying the grade and tonnage of recoverable minerals within the TSF will present a transparent pathway to near-term manufacturing and significant money stream, supporting our technique to quickly advance Winston from an historic asset into a contemporary, cash-generating operation.

We sit up for updating shareholders as work progresses.”

The MRE programme is an integral a part of the method to advance the Winston Tailing Mission by allowing in direction of a cashflow proposition and will probably be based mostly upon the useful resource drilling programme, mineralogical and metallurgical testwork and related research which will probably be performed throughout winter 2025/26.

Panther is aiming for a seamless transition from MRE to Ore Reserves in as brief a time as attainable, and it’s envisaged that profitable outcomes to the tailing MRE, will in flip assist the declaration of Ore Reserves following additional technical research. The MRE work will even present inputs into the Utility for Restoration of Minerals Allow (the “Restoration Allow”) course of as introduced 1 September 2025.^{3, 4}

The MRE will probably be reported in compliance with the requirements and finest practices set out by the Canadian Institute of Mining, Metallurgy and Petroleum’s (“CIM”) for reporting Mineral Assets, Ore Reserves, and associated exploration data. This will even facilitate future NI 43-101 reporting, as required.

Background

The Winston Tailings Mission entails a collection of workstreams to quantify, consider and allow the contained high-grade gold (Au), gallium (Ga), silver (Ag), zinc (Zn), copper (Cu) and cobalt (Co) and different recoverable minerals situated inside the historic Winston Lake Mine tailings storage facility. Reprocessing the mine tailings, probably affords Panther the chance to unlock residual metallic worth and contribute to the long-term environmental rehabilitation of the Winston Mission website.^{1, 2}

The Winston Lake Mine was operational from 1988 to 1998, producing roughly 3.3 million tonnes of ore and yielding zinc, copper, silver, and gold. Primarily based on historic recoveries from mining actions within the Nineteen Eighties and Nineteen Nineties, it’s believed {that a} important amount of worthwhile materials stays within the tailing storage facility.

Obonga Mission – Increasing Canada’s Subsequent VMS and Essential Minerals District

Panther Metals’ Obonga Mission in Ontario continues to display important potential as a number one exploration initiative concentrating on each base and demanding minerals. Since buying the Obonga Greenstone Belt in July 2021, the Firm has quickly superior 5 high-priority targets: Wishbone, Awkward, Survey, Ottertooth, and Silver Rim.

In June 2024, Panther secured a key Exploration Allow for the Wishbone Prospect, legitimate by 2027, authorizing in depth drilling and geophysical surveys. Earlier campaigns confirmed compelling volcanogenic large sulphide (VMS)-style mineralisation, highlighted by intercepts corresponding to 27.3m of large sulphide and 51m of sulphide-dominated mineralisation with a number of mineralised lenses. Excessive-grade copper anomalies in lake sediment additional improve the prospectivity of this landmark goal.

July 2024 noticed Panther awarded an Exploration Allow for Awkward West, supporting an aggressive exploration program together with as much as 31 drill holes. Historic drilling right here revealed notable graphite mineralisation-27.2m at 2.25% Complete Graphitic Carbon (TGC) with zones exceeding 5% TGC-alongside promising indicators of nickel, copper, and platinum group parts, aligning with Panther’s strategic give attention to vital minerals.

Further exploration efforts embody high-resolution magnetic geophysical surveys throughout key prospects, optimizing drill concentrating on and advancing the geological mannequin. Survey and Ottertooth stay extremely potential, with a number of magnetic and electromagnetic anomalies and historic intercepts of large sulphides, many targets nonetheless largely untested.

Obonga’s mixture of VMS-style base metals and demanding mineral potential, located in a secure and mining-friendly jurisdiction with sturdy infrastructure, positions Panther Metals to unlock a district-scale mineral system with important business upside.

Dotted Lake Mission – Hemlo-Adjoining Gold Alternative with Rising Momentum

Panther Metals’ Dotted Lake Mission, acquired in July 2020, lies simply 16km from Barrick Gold’s famend Hemlo Mine, in considered one of Canada’s premier gold-producing areas. The challenge affords a strategically situated and scalable gold exploration play.

Preliminary soil sampling in 2021 recognized quite a few gold and base metallic targets, and subsequent entry enhancements facilitated an preliminary drilling program that confirmed gold mineralisation with anomalous values extending alongside strike.

In early 2025, Panther accomplished a follow-up marketing campaign that includes detailed geological mapping, trenching, and focused diamond drilling. These efforts prolonged mineralisation each laterally and at depth, recognized new structural controls, and bolstered the potential for a broader, high-grade gold system. A number of zones have been prioritised for expanded drilling, underscoring Dotted Lake’s important upside.

The challenge’s proximity to established infrastructure and Hemlo’s in depth mining operations, mixed with strong latest outcomes, makes Dotted Lake a key asset in Panther’s progress portfolio.

Business Technique – Discovery-Pushed Worth Creation

Panther Metals is dedicated to creating substantial shareholder worth by targeted exploration and disciplined capital administration. The Firm combines deep geological experience with an understanding of market and financing dynamics to advance high-potential initiatives effectively.

With entry to a worldwide community of business leaders and a rigorous operational give attention to drilling, Panther prioritises actions that immediately contribute to discovery and useful resource progress. The drill gap stays the final word validation in mineral exploration, and Panther’s technique is to fast-track world-class targets into drill-ready property – delivering tangible outcomes that underpin long-term worth creation for shareholders.
