Premium Commences “Hinge” Drilling Targeting Large BHEM Plates in the 2km Area Between Selebi Deposits

Toronto, Ontario–(June 3, 2025) – Premium Resources Ltd. (TSXV:PREM) (OTC Pink:PRMLF) (“PREM” or the “Company“) is pleased to announce that the surface drilling program is underway in the 2-kilometre gap zone between the Selebi North and Selebi Main deposits (together the “Selebi Mines“). This program is designed to rapidly demonstrate the broader scale potential of the Selebi Mines targeting large borehole electromagnetic (“BHEM“) plates and to further support the Company’s core thesis that these deposits are significantly larger than previously recognized.

Highlights:

• Targeting BHEM plates indicating potential mineralized connection between Selebi North and Selebi Main deposits.
• 12,500 meters of drilling planned across 6 holes, all suitable for future wedge drilling.
• Continued expansion of mineralization at Selebi North.
• Both Selebi North and Selebi Main deposits remain open for expansion through further exploration.

Drilling Program Overview

Two company-owned drill rigs have commenced the first two holes of the deep drilling program, with one drill testing large BHEM plates located down-plunge and down-dip from the Selebi Main mine horizon and trending toward the Selebi North deposit, and the second drill testing BHEM plates located 500 metres down-plunge and down-dip from the Selebi North deposit and trending toward Selebi Main. The program will include approximately 12,500 metres of drilling and is expected to be completed over a five-month period.

Morgan Lekstrom, CEO of Premium Resources commented: “This drilling campaign has the potential to unlock substantial value and marks the delivery of a long-anticipated commitment to the market. We are proud to be advancing this asset aggressively on multiple fronts. Drilling at the Selebi hinge represents a pivotal step in our growth strategy, with numerous additional catalysts expected in the near term. Beyond the hinge, we are actively advancing both of our core assets this year, with a clear goal to become the next major source of critical metals, anchored in a Tier One mining jurisdiction.”
