8-K: Premium Resources Extends Selebi Project Mineralization by 315 Meters, Signaling Significant Expansion Potential

Premium Resources Ltd. announced successful drilling at its Selebi North Underground project, extending mineralization 315 meters down-plunge from the existing resource model and indicating further expansion potential.

Summary

• Premium Resources Ltd. has achieved another successful intercept of mineralization at its Selebi North Underground (SNUG) project, targeting down-plunge expansion.
• Drill hole SNUG-25-186 intersected South Limb mineralization over 16.20 metres, located 132 metres down-plunge from the previously announced drill hole SNUG-25-184.
• Combined, drill holes SNUG-25-186 and SNUG-25-184 have extended the South Limb mineralization by 315 meters down-plunge from the lower boundary of the 2024 resource model.
• Borehole electromagnetic (BHEM) survey results suggest a thicker interval of mineralization lies immediately to the northwest of drill hole SNUG-25-186.
• The current resource model for the Selebi project has a down-plunge extent of 965 metres, and existing resources show strong grades, well over 3% Copper Equivalent (CuEq).

Sentiment

Score: 8

Explanation: The document conveys a highly positive sentiment, driven by significant drilling success that extends known mineralization, the indication of even thicker mineralization, and strong existing grades. Management's comments are very optimistic about the deposit's expansion potential. The primary cautionary notes relate to standard disclaimers about resource classification and forward-looking statements, rather than negative operational news.

Positives

• Successful drilling extended South Limb mineralization by 315 meters down-plunge, significantly expanding the known deposit beyond the 2024 resource model.
• Borehole electromagnetic (BHEM) results indicate potential for a thicker mineralization interval immediately northwest of the latest drill hole, suggesting further upside.
• The existing resource boasts strong grades, exceeding 3% Copper Equivalent (CuEq), which enhances the economic potential of the expanded mineralization.
• The company's effective use of BHEM technology has enabled precise targeting of deep extensions.
• Follow-up drilling is already underway to define the strike extent of the new down-plunge extension, indicating proactive exploration.

Risks

• There is no assurance that any mineral resources reported as indicated or inferred under Canadian NI 43-101 will be the same as reserve or resource estimates prepared under SEC S-K 1300, due to some differences in the rules.
• Investors should not assume that any part or all of indicated or inferred mineral resources will ever be converted into a higher category of mineral resources or into mineral reserves, as mineralization described using these terms has a greater amount of uncertainty regarding existence and feasibility.
• Inferred resources have a greater amount of uncertainty as to their existence and whether they can be mined legally or economically, and cannot form the basis of feasibility or other economic studies, except in limited circumstances.
• Actual events, results, performance, prospects, and opportunities could differ materially from forward-looking information due to various risks and uncertainties.
• Capital and operating costs may vary significantly from estimates.
• Metallurgical test results are preliminary in nature.
• Exploration results may not accurately predict mineralization, prefeasibility, or the feasibility of mine production.
• Delays in obtaining or failures to obtain required governmental, environmental, or other project approvals could occur.
• Uncertainties exist regarding the availability and costs of future financing.
• Changes in equity markets, inflation, and fluctuations in commodity prices could negatively impact the company.
• Delays in the development of projects are possible.
• Other inherent risks are involved in the mineral exploration and development industry.

Future Outlook

Premium Resources plans further drilling to define the strike extent of the newly identified down-plunge extension. Assay results for the 2025 drill holes are anticipated in early July. The company also anticipates sharing several other exciting initiatives with the market soon, and aims to potentially publish an updated mineral resource estimate or future prefeasibility study, with a belief that the Selebi and Selebi North deposits may be connected at depth.

Management Comments

• The significant step-outs and ongoing expansion that we are achieving, in the time frame, clearly illustrates that this deposit expands well beyond the boundaries of the current resource area.
• Given the strong grades in our existing resource well over 3% CuEq, each successful step-out highlights the potential that was previously undefined.
• Our use of BHEM and our deep understanding of the technology has enabled us to target and drill these step-downs with a high degree of precision.
• While the current resource has a down-plunge extent of 965 metres, our drilling has intercepted more massive sulphides (host to the copper, nickel and cobalt) and extended the deposit by approximately 315 meters.
• We have several exciting initiatives running in parallel which we look forward to sharing with the market very soon.

Industry Context

This announcement highlights ongoing exploration success in the base metals sector, particularly for nickel, copper, and cobalt, which are critical minerals for the global energy transition. The extension of known mineralization at a previously producing mine like Selebi in Botswana aligns with the industry trend of re-evaluating and expanding existing deposits using modern exploration techniques like BHEM, especially in established mining jurisdictions. The focus on down-plunge extensions is a common strategy to increase resource longevity and potential economic viability.

Comparison to Industry Standards

• The extension of 315 meters down-plunge from an existing 965-meter resource model represents a significant percentage increase in the known extent of mineralization, which is a strong indicator of potential resource growth compared to typical incremental exploration updates.
• The reported grades of "well over 3% CuEq" are considered high-grade for a bulk tonnage base metal deposit, comparing favorably to many global copper-nickel projects that often operate on lower grades.
• The use of Borehole Electromagnetic (BHEM) surveys for precise targeting of conductive massive sulphides is a standard and effective industry practice for identifying extensions of known deposits, demonstrating the company's application of advanced geophysical methods.
• While specific comparable companies or projects are not named in the document, the successful step-out drilling and grade profile suggest the Selebi project could become a notable asset in the African base metals landscape, potentially comparable to other high-grade nickel-copper sulphide deposits globally, if further economic studies confirm viability.

Stakeholder Impact

• Shareholders/Investors: Positive impact due to significant resource expansion potential, which could lead to increased asset value and future production prospects. The detailed disclosure on resource classification (NI 43-101 vs. S-K 1300) provides clarity on reporting standards.
• Employees: Continued exploration and potential future mine redevelopment could lead to job security and growth opportunities, particularly for local Batswana staff involved in BHEM surveys.
• Local Communities (Botswana): Potential for long-term economic benefits through mine redevelopment, employment, and local procurement, aligning with the company's focus on the Republic of Botswana.
• Creditors/Lenders: Improved confidence in the company's asset base and future cash flow potential, which could facilitate future financing.

Next Steps

• The next drill hole is underway to define the strike extent of the down-plunge extension.
• Follow-up drilling (SNUG-25-189) is underway to further evaluate the continuity and scale of both the South Limb and N2 mineralized systems.
• Assays for 2025 drill holes are expected in early July and will be released as received.
• The company looks forward to sharing several other exciting initiatives with the market very soon.
• Potential publication of an updated mineral resource estimate or future prefeasibility study.
