Premium Nickel Resources Ltd. has released additional assay results from drilling at its past-producing nickel-copper-cobalt sulphide Selebi North underground mine in Botswana. Previous results for 16 holes were released, November 14, November 27 and December 19, 2023, respectively. Results for a further seven holes are released herein. To date a total of 23 holes have been released representing an aggregate of approximately 8,242 metres including the holes and metres released herein. Details of the assay results are shown below along with accompanying visuals via Figure 1 and Figure 2. Drill core photos for all holes released to date, including the holes reported herein, are accessible by Clicking Here and can also be found on the Company website at www.premiumnickelresources.com.

Highlights include:

• SNUG-23-055 (South Limb): 15.30 metres of 2.96% NiEq (1.84% Ni; 1.85% Cu; 0.10% Co)
  • including 8.45 metres of 3.07% NiEq (2.15% Ni; 1.40% Cu; 0.11% Co) and 3.00 metres of 3.01% NiEq (2.13% Ni; 1.28% Cu; 0.12% Co)
• SNUG-23-054 (N3 Limb): 6.85 metres of 4.01% NiEq (2.72% Ni; 1.97% Cu; 0.15% Co)
• SNUG-23-053 (South Limb): 6.05 metres of 2.78% NiEq (1.95% Ni; 1.23% Cu; 0.11% Co)

Keith Morrison, CEO of PNRL, commented: “The Company is very encouraged with these and past results as they continue to further substantiate our views that higher grade zones relating to the conductive massive sulphide Ni-Cu-Co mineralization exist at Selebi North underground. During the Holiday season we completed additional borehole EM surveys in the area down plunge from these mineralized structures at the Selebi North deposit. Our underground drilling will now continue to progress down plunge, aiming to intercept additional mineralization that was not accounted for in the historic resource.”

The purpose of this drill program is to define mineralization down plunge of the existing workings that will be used to complete a Mineral Resource Estimation (“MRE”) prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). Assay results are given below in Table 1 and hole collar details are given in Table 2. Figures 1 and 2 show the location of holes relative to the historic resource and underground infrastructure.

The various mineralized zones have been historically mined and subsequently named N2 Limb, N3 Limb and South Limb to demarcate their location on the folded mineralized horizon. Additional drilling is needed to estimate true width and define the folded mineralization.

Drilling Continues

Two drills have been mobilized to the 810 metre level exploration drift, permitting testing areas further down plunge of the three mineralized zones with the aim to demonstrate upside potential that will support a future MRE.

As of January 17, 2024, a total of 18,120 metres in 49 drillholes have been completed from the initial three underground drill bays and 514 metres have been drilled from two drill bays on the 810mL exploration drift. During this initial phase, drilling is targeting the area down plunge of mine infrastructure to characterize the remaining resource. Assay results for completed holes will be released as they are received and confirmed by the Company.

Quality Control

The underground drilling program is being carried out through an agreement with Forage Fusion Drilling Ltd. of Hawkesbury, Ontario, Canada, who have provided three Zinex U-5 drills for purchase and training of local operators. Drill core samples are BQTK (40.7 mm diameter). All samples are one-half core cut by a diamond saw on site. Half of the core is retained for reference purposes. Samples are generally 1.0 to 1.5 metre intervals or less at the discretion of the site geologists. Sample preparation and lab analysis was completed at the ALS Chemex in Johannesburg, South Africa. Commercially prepared blank samples and certified Cu/Ni sulphide analytical control standards with a range of grades are inserted in every batch of 20 samples or a minimum of one set per sample batch. Analyses for Ni, Cu and Co are completed using a peroxide fusion preparation and ICP-AES finish (ME-ICP81).

Holes are numbered as follows: SNUG (Selebi North Underground) + year + hole number starting at 013.

Technical Report

Scientific and technical information relating to the Selebi Mine is supported by the technical report titled “Technical Report on the Selebi Mines, Central District, Republic of Botswana, Report for NI 43-101”, dated June 16, 2022 (effective date of March 1, 2022) (the “Selebi Technical Report”), and prepared by SLR Consulting (Canada) Ltd. for PNRL. Reference should be made to the full text of the Selebi Technical Report, including the assumptions, limitations and data verification therein relating to the historic data compilation presented in this news release, which was prepared in accordance with NI 43-101 and is available electronically on SEDAR+ (www.sedarplus.com) under PNRL’s issuer profile.

Historic Resource Estimate

The historical mineral resource estimate referenced herein (the “Historic Resource”) was calculated for the Selebi North, Selebi Main, Phikwe South and Southeast Extension deposits in accordance with SAMREC, in 2016, and does not comply with NI 43-101. To that end, the Historic Resource is considered to be historical in nature and should not be relied upon as a current mineral resource estimate. While management believes that the Historic Resource could be indicative of the presence of mineralization on the deposits, a qualified person for purposes of NI 43-101 has not completed sufficient work to classify the historical mineral estimates as current mineral resource estimates and PNRL is not treating the historical mineral estimates as current mineral resource estimates.

About Premium Nickel Resources Ltd.

PNRL is a mineral exploration and development company that is focused on the redevelopment of the previously producing nickel, copper and cobalt resources mines owned by the Company in the Republic of Botswana. We are driven by our belief that the demand for these metals will continue to grow in the medium to long term, as a result of global urbanization and the increasing adoption of electric motors over internal combustion engines. These metals are vital for achieving a low-carbon future.

PNRL is committed to governance through transparent accountability and open communication within our team and our stakeholders. Our skilled team has worked over 100 projects collectively, accumulating over 400 years of resource discoveries, mine development and mine re-engineering experience on projects like the Company’s Selebi and Selkirk mines. PNRL’s senior team members have on average more than 20 years of experience in every single aspect of mine discovery and development, from geology to operations.
