Premium Commences Resource Expansion Through Drilling and Comprehensive Metallurgy Optimization at Selkirk

May 15, 2025 3:30 AM EDT | Source: Premium Resources Ltd.

Toronto, Ontario--(Newsfile Corp. - May 15, 2025) - Premium Resources Ltd. (TSXV: PREM) (OTC Pink: PRMLF) ("PREM" or the "Company") announces that a surface drilling program is underway and provides details of the work program at its past-producing copper-nickel-cobalt-platinum group elements ("Cu-Ni-Co-PGE") sulphide Selkirk mine ("Selkirk Mine") in Botswana. The drilling program is designed to demonstrate resource expansion and metallurgical flowsheet development. These initiatives are aimed at de-risking the project to support future development decisions.

Highlights of Selkirk Work Program

Drilling program initiated - A 12-hole drill program is underway at Selkirk (Figure 1), focused on twinning historical holes to validate legacy data, adding key data points to support a future resource model update, and resource expansion through continued resampling of historical core (See news release April 10, 2025).
Continued resampling of historical core - In 2024, 17 historical drill holes were resampled to obtain complete PGE analysis (See press releases dated October 28, 2024, titled: "Selkirk Deposit Provides Strong Historic Drill Core Results Including 186.25 Metres of 1.65% CuEq"). An additional 34 historical holes have been identified for resampling.
Metallurgical program ongoing - Aimed at refining orebody domains and developing a more comprehensive, de-risked metallurgical model reflected in an updated Mineral Resource Estimate ("MRE") and supporting studies.

Morgan Lekstrom, CEO of Premium Resources states: "Resampling the historical drill core has proven to be a cost-effective and impactful way to enhance our understanding of the Selkirk deposit. This phase of drilling will prove critical for resource reclassification as we rapidly advance toward restoring the project's legacy resource estimate. We remain focused on accelerating Selkirk and positioning it for near future development."

The surface drilling program will collect fresh HQ-sized core to support metallurgical flowsheet, generate material for preliminary X-ray Transmission ("XRT") ore-sorting tests, and support the potential expansion and upgrade of the National Instrument 43-101 ("NI 43-101") compliant 44.2Mt Inferred MRE to the Indicated category (see news release dated November 27, 2024).

Historical production at the Selkirk Mine took place between 1989 and 2002 with Anglo American mining high grade Cu-Ni massive sulphides and producing 1 million tonnes at 2.6% Ni and 1.5% Cu. Thereafter, in 2006, LionOre Mining International Ltd. ("LionOre") published a technical report in accordance with NI 43-101 and more recently in 2013, Norilsk Nickel Africa commissioned GiproNickel Institute to calculate an updated mineral resource estimate in accordance with JORC Code (Joint Ore Reserves Committee) that demonstrated a historical resource of 128.4 Mt 0.21% Ni, 0.23% Cu Measured & Indicated / 123.8 Mt 0.17% Ni, 0.19% Cu Inferred (See Historical Estimates).

The Company will continue to provide regular updates as drilling activities progress and metallurgical test work advances.

Historical Estimates

Certain of the mineral resource estimates referred to in this release are historical in nature and should not be relied upon as a current mineral resource estimate. While management believes that these historical mineral resource estimates could be indicative of the presence of mineralization on the Selkirk Mine property, a "qualified person" (for purposes of NI 43-101) has not completed sufficient work to classify the historical mineral estimates as a current mineral resource estimates and the Company is not treating the historical mineral estimates as current mineral resource estimates.
