Panther Metals Plc (LSE: PALM), the exploration company focused on mineral projects in Canada, is pleased to announce that Platinum Diamond Drilling Inc. (‘Platinum’) has been contracted to undertake the Mineral Resource focussed drilling programme at the Winston Tailings Project in Ontario, Canada.^{1, 2, 3}

The appointment of Platinum follows on from the appointment of SRK Exploration Ltd (‘SRK EX’) as independent consultants to conduct the Mineral Resource estimate (‘MRE’).

The MRE will be one of a series of workstreams to quantify, evaluate and permit the contained high-grade gold (Au), gallium (Ga), silver (Ag), zinc (Zn), copper (Cu) and cobalt (Co) and other recoverable minerals located within the historic Winston Lake Mine tailings storage facility (‘TSF’).

Darren Hazelwood, Chief Executive Officer commented:

‘The appointment of a drilling contractor for the Winston Tailings Project marks a pivotal step forward for the Company. This programme is designed to validate the historic recovery production and produce a CIM compliant Mineral Resource estimate, a key milestone in taking the project through the recovery permitting process.

The historical Winston Lake mine processing data indicates that the tailings have the potential to host commodities in quantities significant enough to fundamentally transform our business.

Quantifying the grade and tonnage of recoverable minerals in the TSF will provide a clear pathway to near-term production and meaningful cash flow, supporting our strategy to rapidly advance Winston from an historic asset into a modern, cash-generating operation.

We look forward to updating shareholders as work progresses.’

The MRE programme is an integral part of the process to advance the Winston Tailing Project through permitting towards a cashflow proposition and will be based upon the resource drilling programme, mineralogical and metallurgical testwork and associated studies which will be conducted during winter 2025/26.

Panther is aiming for a seamless transition from MRE to Ore Reserves in as short a time as possible, and it is envisaged that successful outcomes to the tailing MRE, will in turn support the declaration of Ore Reserves following further technical studies. The MRE work will also provide inputs into the Application for Recovery of Minerals Permit (the ‘Recovery Permit’) process as announced 1 September 2025.^{3, 4}

The MRE will be reported in compliance with the standards and best practices set out by the Canadian Institute of Mining, Metallurgy and Petroleum’s (‘CIM’) for reporting Mineral Resources, Ore Reserves, and related exploration information. This will also facilitate future NI 43-101 reporting, as required.

Background

The Winston Tailings Project entails a series of workstreams to quantify, evaluate and permit the contained high-grade gold (Au), gallium (Ga), silver (Ag), zinc (Zn), copper (Cu) and cobalt (Co) and other recoverable minerals located within the historic Winston Lake Mine tailings storage facility. Reprocessing the mine tailings, potentially offers Panther the opportunity to unlock residual metal value and contribute to the long-term environmental rehabilitation of the Winston Project site.^{1, 2}

The Winston Lake Mine was operational from 1988 to 1998, producing approximately 3.3 million tonnes of ore and yielding zinc, copper, silver, and gold. Based on historic recoveries from mining activities in the 1980s and 1990s, it is believed that a significant quantity of valuable material remains in the tailing storage facility.

Obonga Project – Expanding Canada’s Next VMS and Critical Minerals District

Panther Metals’ Obonga Project in Ontario continues to demonstrate significant potential as a leading exploration initiative targeting both base and critical minerals. Since acquiring the Obonga Greenstone Belt in July 2021, the Company has rapidly advanced five high-priority targets: Wishbone, Awkward, Survey, Ottertooth, and Silver Rim.

In June 2024, Panther secured a key Exploration Permit for the Wishbone Prospect, valid through 2027, authorizing extensive drilling and geophysical surveys. Previous campaigns confirmed compelling volcanogenic massive sulphide (VMS)-style mineralisation, highlighted by intercepts such as 27.3m of massive sulphide and 51m of sulphide-dominated mineralisation with multiple mineralised lenses. High-grade copper anomalies in lake sediment further enhance the prospectivity of this landmark target.

July 2024 saw Panther awarded an Exploration Permit for Awkward West, supporting an aggressive exploration program including up to 31 drill holes. Historic drilling here revealed notable graphite mineralisation-27.2m at 2.25% Total Graphitic Carbon (TGC) with zones exceeding 5% TGC-alongside promising signs of nickel, copper, and platinum group elements, aligning with Panther’s strategic focus on critical minerals.

Additional exploration efforts include high-resolution magnetic geophysical surveys across key prospects, optimizing drill targeting and advancing the geological model. Survey and Ottertooth remain highly prospective, with multiple magnetic and electromagnetic anomalies and historic intercepts of massive sulphides, many targets still largely untested.

Obonga’s combination of VMS-style base metals and critical mineral potential, situated in a stable and mining-friendly jurisdiction with strong infrastructure, positions Panther Metals to unlock a district-scale mineral system with significant commercial upside.

Dotted Lake Project – Hemlo-Adjacent Gold Opportunity with Growing Momentum

Panther Metals’ Dotted Lake Project, acquired in July 2020, lies just 16km from Barrick Gold’s renowned Hemlo Mine, in one of Canada’s premier gold-producing regions. The project offers a strategically located and scalable gold exploration play.

Initial soil sampling in 2021 identified numerous gold and base metal targets, and subsequent access improvements facilitated an initial drilling program that confirmed gold mineralisation with anomalous values extending along strike.

In early 2025, Panther completed a follow-up campaign featuring detailed geological mapping, trenching, and targeted diamond drilling. These efforts extended mineralisation both laterally and at depth, identified new structural controls, and reinforced the potential for a broader, high-grade gold system. Multiple zones have been prioritised for expanded drilling, underscoring Dotted Lake’s significant upside.

The project’s proximity to established infrastructure and Hemlo’s extensive mining operations, combined with robust recent results, makes Dotted Lake a key asset in Panther’s growth portfolio.

Commercial Strategy – Discovery-Driven Value Creation

Panther Metals is committed to creating substantial shareholder value through focused exploration and disciplined capital management. The Company combines deep geological expertise with an understanding of market and financing dynamics to advance high-potential projects efficiently.

With access to a global network of industry leaders and a rigorous operational focus on drilling, Panther prioritises activities that directly contribute to discovery and resource growth. The drill hole remains the ultimate validation in mineral exploration, and Panther’s strategy is to fast-track world-class targets into drill-ready assets – delivering tangible results that underpin long-term value creation for shareholders.

GRANDE PRAIRIE, ALBERTA TheNewswire – (Nov. 20, 2025): Angkor Resources Corp. (TSXV: ANK,OTC:ANKOF) (‘ANGKOR’ OR ‘THE COMPANY’) announces further analysis, assays, and conclusions on the drill core from Andong Bor license in Oddar Meanchey Cambodia.

Dennis Ouellette, VP Exploration for Angkor, with associate geologists has reviewed the Andong Bor drill core from historical drilling with the most recently 2025 drilled holes 009 and 010.  The two new holes (ABDDH25 -009, -010), of which 009 was substantially deeper, has sections of drill core, roughly from 245 metres to 316 metres in which mineralization with abundant pyrite and chalcopyrite was observed.

Previously, in late 2022, analysis was based only on core drilled by a different company. (see  press release ANGKOR CONFIRMS 108 METRES OF 0.53% COPPER EQUIVALENT AT ANDONG BOR, CAMBODIA | Angkor Resources Corp. )The 2025 drill core from both holes is being logged in detail and cut for sampling purposes.

Further conclusions from the analysis indicate that the structural relationship between the intrusive rock and the host sedimentary rock was not revealed in the previous drilling (ADBDH16-005, -006, -007, -008) as all the contacts were faulted or there was poor core recovery at those sites.

Figure 2 Drill core marked for cutting (see pink lines on core at bottom of picture).

Mr. Ouellette summarizes findings, ‘The best copper mineralization in Andong Bor diamond drill core is hosted by the sedimentary rocks. The diorite (coarse-grained rock) feldspar porphyry intrusive rocks can host low grade copper porphyry-style mineralization, such as ‘B’ and ‘D’ style veins and disseminations. However, in proximity to the highly reactive wallrock (where the intrusive rock is surrounded by the sedimentary rock), the assay values increase dramatically.’

He continues with other conclusions, ‘ The contacts where sedimentary rock and intrusive rock have met are very steep – from 70 to 80 degrees. Mineralization within the sediments is both disseminated and along fractures parallel to these contacts. This implies significant ground preparation (probably with magma or similar catalysts) prior to mineralization.   The sedimentary (country) rock was heavily fractured, so when the intrusion and mineralization events occurred, they followed the pre-existing fractures.  Knowing this impacts the design of our continuation of the drill program in a manner which we expect will result in both shallower and increased mineralized intercepts.’

Assays will be forwarded to ALS when all core cutting is completed and plans for continuation of drilling extend into 2026.

Critical Mineral Resources plc (“CMR”, “Company”) is delighted to announce the arrival of its diamond core drilling rig at Agadir Melloul, marking a major step forward that puts the project in an excellent position to accelerate drilling activity. The team is now focused on commissioning the rig as quickly as possible, with the first bore hole expected to be drilled during the first half of December.

Highlights

The Company’s fully refurbished Discovery HD track-mounted diamond core drill has arrived at Agadir Melloul. Some important features:

• Fitted with brand new Caterpillar 308E steel tracks for rapid moves between drill pads
• Compact, robust design with a heavy-duty telescopic mast and powerful hoisting winch capable of pulling the complete drill string from the ground and pulling in 20 ft sections
• Drilling depth capacity of 1400m NQ (47.6mm core), 876m HQ (63.5mm core)
• Delivered with new consumable parts such as jaws, bushings and comprehensive remote site spares kit to minimise risk of downtime

The rig is expected to be operational during the first half of December, almost immediately doubling our drilling capacity.

Charlie Long CEO commented:

“It has been quite a journey for our Discovery HD rig and its arrival represents an important milestone for the project. The rig has undergone a comprehensive refurbishment and is effectively as good as new. With proper care, we expect it to deliver consistent performance for the next decade and provide significant per metre cost savings.

Multi Power, the manufacturer, was extremely supportive, generously installing a brand new feed cylinder, instead of resealing the original, replacing key components including foot clamp, and completely stripping and professionally repainting the mast. New Cat 308E tracks were also sourced and installed to ensure maximum efficiency.

The additional refurbishment and some shipping complications meant the rig arrived later than originally planned. It is a testament to our team on the ground, and the advantages of operating in Morocco, that once we knew of the delay, we were quickly able to secure the services of a trusted drilling contractor who began work immediately, ensuring that progress continued uninterrupted.

We are now carefully unpacking and inspecting all components, and with our newly appointed drill operator already in place, the team is ready to commission and bring the rig into operation without delay. The arrival of our rig puts us in an excellent position to significantly accelerate drilling and to advance on all fronts, simultaneously drilling both the sedimentary copper deposit and the exciting new Rhyolite discovery.

We look forward to seeing the Discovery HD drill its first holes in the first half of December”.
