Premium Commences Resource Expansion

Through Drilling and Comprehensive

Metallurgy Optimization at Selkirk

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.

The scientific and technical content of this news release has been reviewed and approved by Sharon

Taylor, Vice President Exploration of the Company, who is a "qualified person" for the purposes of

National Instrument 43-101.

Technical Report

The Mineral Resource Estimate on the Selkirk Mine is supported by the technical report entitled "NI 43-

101 Technical Report Selkirk Nickel Project, North East District, Republic of Botswana", dated

November 1, 2024 (with an effective date of January 10, 2025) (the "

Technical Report

") prepared by

SLR Consulting (Canada) Ltd. for PREM. Reference should be made to the full text of the Technical

Report for the assumptions, qualifications and limitations set forth therein, a copy of which is available on

SEDAR+ (

) under PREM's issuer profile.

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.
