2024 Rodburn Drilling Update

News & Media 2024 Rodburn Drilling Update Drilling resumes at the Rodburn high-grade Ni-Cu-Co project in Aberdeenshire, Scotland Peak Nickel Limited (“PNL” or the “Company”) is pleased to provide an update on exploration activities at Rodburn, the highest-grade battery metals project in the UK, where the 2024 drill programme is now underway. During 2023 the Company conducted an 18-hole 2,600m drill programme to test the areas around historically identified, non-compliant mineral resources (for more details refer to PNL press releases dated 21st February 2024 and 2nd March 2024). As a result, a new Mineral Resource Estimate was defined as outlined below. Resource Mt Ni (%) Cu (%) Co (ppm) % NiEq. Inferred Mineral Resource 4.3 0.54 0.28 364 0.72 Including 2.9 0.67 0.35 457 0.90 Download Report

New Board Appointments

News & Media New Board Appointments New Director Appointments Richard Williams Joins PNL Board Following a Successful Period Running UK Tin Developer Cornish Metals Inc. Peak Nickel Limited (PNL) is pleased to provide a corporate update as follows: PNL has appointed Mr. Richard David Williams as a director of the company. Mr Williams has over 35 years global experience in the mining and minerals industry, most notably as CEO and director of Cornish Metals Inc., where he was intimately involved in the acquisition, funding, and development of the South Crofty tin mine in Cornwall. In addition to Mr. Williams, PNL has added shareholder Ormonde Mining Ltd.’s nominee, Mr Steven Nicol, to the PNL board (with Mr Brendan McMorrow as his Alternate). Peak Nickel Limited is a private mineral exploration company – more information is available at www.peaknickel.co.uk and info@peaknickel.co.uk. The company recently released the following resource, confirming Rodburn’s status as the highest-grade battery metals resource in the UK: Resource Mt Ni (%) Cu (%) Co* (ppm) NiEq. (%) Global 4.3 0.54 0.28 364 0.72 Including 2.9 0.67 0.35 457 0.90 Download Report The resource was estimated by an independent Qualified Person with over 10 years’ experience in mineral resource estimation. All technical information contained within this document has been reviewed and approved by Mr. C. MacKenzie, M.Sc., C.Geol (CM), a Director and Control Person of PNL. CM has previously acted as a Qualified Person (as defined by Canadian National Instrument NI 43-101 Standards of Disclosure for Mineral Projects) and a Competent Person (under JORC 2012) for various public companies.

Ni%-equivalent values used by the independent QP were calculated based on metal prices of $19,000/t Ni, $8,500/t Cu, $28,000/t Co, using the formula Ni% + (0.447 x Cu%) + (1.474 x Co%) and exclude any precious metal credits.

New Resource Announced

News & Media New Resource Announced Rodburn Ni-Cu-Co Project: Maiden Resources Increases Historical Estimates  Peak Nickel Limited (PNL) is pleased to provide the results from the maiden resource at the advanced Rodburn Project in Scotland, summarised below: 4.3Mt @ 0.72 Ni Eq(%) including 2.9Mt @ 0.9 Ni Eq(%) – wide open The higher-grade zone doubles the previous 1973 estimate by Exploration Ventures Ltd. (“EVL”, a RioTinto-Consolidated Gold Fields joint venture). The resource was compiled using PNL’s recently announced drill results (see News Release dated 21st February 2024). The 2023 drill programme comprised 2,600m of drilling in 18 holes testing a 900m strike length of a variably mineralised basic-ultrabasic unit intruding gabbroic and metasedimentary rocks. Mineralisation consists of pyrrhotite, chalcopyrite & pentlandite.  The global resource contains 23,100t Ni, 12,100t Cu and 1,560t Co and remains completely open to depth and along strike in most directions. The resource block model indicates a higher-grade plunging shoot raking NE on the main mineralised zone, which strikes NE-SW and dips at approximately 50° NW. The deepest hole on this shoot is a historical hole from 1973 which intercepted 9.85m @ 1.06% Ni and 0.34% Cu (open) approximately 140m deep, see Figure 1 below. No Co assays are available for historical holes.  Further drilling is planned in 2024 to investigate the true scale of the resource zone.  PNL will be displaying drill core from Rodburn at the PDAC – Find us at Booth #3149  Peak Nickel Limited is a private mineral exploration company – more information is available at www.peaknickel.co.uk and info@peaknickel.co.uk The resource was estimated by an independent Qualified Person with over 10 years’ experience in mineral resource estimation.  All technical information contained within this document has been reviewed and approved by Mr. C.

2023 Drilling Results

News & Media 2023 Drilling Results Rodburn Ni-Cu-Co Project: 2023 Drilling Results Table 1 – Collar Information (Local grid) Peak Nickel Limited (PNL) is pleased to provide the results from it’s maiden 2023 drilling programme at the advanced Rodburn Project in Scotland. Headline drill intercepts include: 5.97m @ 1.92% Ni, 1.50% Cu, 0.12% Co 13.8m @ 1.39% Ni, 0.53% Cu, 0.07% Co Incl 5.39m @ 2.04% Ni, 0.56% Cu, 0.1% Co 17m @ 1.16% Ni, 0.51% Cu, 0.08% Co 9m @ 1.13% Ni, 0.73% Cu, 0.11% Co More than 2,600m of drilling investigated a 900m strike length of a variably mineralised basic ultra basic unit intruding gabbroic and metasedimentary rocks. Sulphide mineralisation consists of pyrrhotite, chalcopyrite and pentlandite. The main zone of mineralisation discovered remains open to depth and along strike. Further drilling is planned in 2024 to investigate the true potential of the zone. Maximum analytical grades (1),were as follows: Ni = 3.55%, Cu = 3.97%, Co = 0.24%, Ag = 12.0ppm, Au = 0.92ppm, Pd = 0.11ppm.
