8-K: Premium Nickel Resources Announces Initial Mineral Resource Estimate for Selebi Mines, Botswana

Premium Nickel Resources Ltd. has released its initial mineral resource estimate for the Selebi Mines in Botswana, showing significant increases in tonnage compared to historical estimates.

Summary

• Premium Nickel Resources Ltd. has announced its initial Mineral Resource Estimate (MRE) for the Selebi Mines in Botswana, effective June 30, 2024.
• The Selebi Main deposit has an inferred mineral resource of 18.89 million tonnes at 3.51% copper equivalent (CuEq) or 1.70% nickel equivalent (NiEq), containing 165,000 tonnes of nickel and 319,000 tonnes of copper.
• The Selebi North deposit has an indicated mineral resource of 3.00 million tonnes at 2.92% CuEq or 1.42% NiEq, containing 29,000 tonnes of nickel and 27,000 tonnes of copper.
• The Selebi North deposit also has an inferred mineral resource of 5.83 million tonnes at 3.11% CuEq or 1.51% NiEq, containing 62,000 tonnes of nickel and 52,000 tonnes of copper.
• The total combined inferred resource for both deposits is 24.7 million tonnes, containing 227,000 tonnes of nickel and 371,000 tonnes of copper.
• The Selebi Main MRE tonnage is 67% larger than the historic resource, and the Selebi North MRE tonnage is 90% larger than the historic resource.
• The company is planning to complete a Preliminary Feasibility Study (PFS) by the end of H1 2025.
• The company aims to potentially reopen the Selebi Mine in late 2027.

Sentiment

Score: 8

Explanation: The document presents a very positive outlook with significant increases in resource estimates, a clear path to a Preliminary Feasibility Study, and a potential mine reopening. The management's comments are also optimistic, and the company is using industry-standard practices. However, there are some risks and uncertainties associated with the project, which temper the overall sentiment slightly.

Positives

• The Mineral Resource Estimate confirms a strong starting resource size and grade.
• Ongoing borehole electromagnetics and drilling continue to demonstrate that both deposits extend down dip and down plunge.
• The MRE identifies good mineralization continuity, mineable widths, and mining dilution characteristics.
• The Selebi Mines are permitted for mining and have key operational infrastructure already in place.
• The mines are supported by a skilled workforce.
• The contained copper significantly exceeds nickel in the total combined contained metal in the two deposits.
• The company has a clear path to a Preliminary Feasibility Study (PFS) and potential mine reopening.

Negatives

• Cobalt, a potentially valuable by-product, has not been included in this initial MRE due to inconsistent data availability.
• The mineral resources are not mineral reserves and do not have demonstrated economic viability.
• There is no assurance that any mineral resources will be converted into a higher category of mineral resources or into mineral reserves.

Risks

• There is a risk that actual results could differ materially from forward-looking statements due to various factors.
• Capital and operating costs may vary significantly from estimates.
• Metallurgical test results are preliminary.
• There are uncertainties relating to the availability and costs of financing needed in the future.
• Changes in equity markets and fluctuations in commodity prices could impact the project.
• Delays in obtaining required governmental, environmental, or other project approvals could occur.

Future Outlook

The company plans to continue drilling to expand the resource and reclassify inferred resources to indicated, complete metallurgical testing, and advance to a Preliminary Feasibility Study (PFS) by the end of H1 2025, with a potential mine reopening in late 2027.

Management Comments

• Keith Morrison, CEO of PNRL, stated that the Mineral Resource Estimate at the Selebi Mines is very promising.
• He believes the results confirm a strong starting resource size and grade which they expect will expand as they continue their drilling program.
• He also noted that the contained copper significantly exceeds nickel in the total combined contained metal in the two deposits.
• He mentioned that the company is working towards a potential mine reopening in late 2027.

Industry Context

This announcement is significant in the context of the nickel and copper mining industry, as it highlights the potential for redevelopment of previously producing mines. The increased resource estimates and the focus on high-grade mineralization position Premium Nickel Resources as a notable player in the sector. The company's focus on a potential mine reopening in late 2027 also indicates a positive outlook for the future of the project.

Comparison to Industry Standards

• The company is using CIM (2014) definitions for mineral resources, which are incorporated in National Instrument 43-101, a standard for public disclosure of mineral projects in Canada.
• The company is also complying with the SEC's new mining disclosure rules (S-K 1300), which are more closely aligned with NI 43-101.
• The use of a Net Smelter Return (NSR) cut-off value of US$70/tonne is a common practice in the industry for determining the economic viability of mineral resources.
• The company's approach to resource estimation, including the use of Leapfrog Geo and Leapfrog Edge software, is consistent with industry best practices.
• The company's drilling program and the use of borehole electromagnetic surveys are also standard practices in the mining industry.
• The company's focus on metallurgical testing and recovery estimates is also a standard practice for advancing a mining project.

Stakeholder Impact

• Shareholders will likely view the increased resource estimates and the potential for mine reopening positively.
• Employees will benefit from the continued operation and potential expansion of the mine.
• The local community in Botswana will benefit from the economic activity generated by the mine.
• Suppliers and creditors will benefit from the company's continued operations and development plans.

Next Steps

• The company will finalize and file the NI 43-101 Technical Report on SEDAR+ within 45 days of the news release.
• The company will continue drilling at both the Selebi Main and Selebi North deposits to re-classify Inferred resources to Indicated and to expand the resource.
• The company will complete bench scale metallurgical testing and recovery estimates to a pre-feasibility standard.
• The company will finalize arrangements for a consultant for the Preliminary Feasibility Study (PFS).
• The company will continue to rapidly redevelop the Selebi Mine working towards a potential mine reopening in late 2027.
