VANCOUVER, B.C. – Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) (“Liberty Goldˮ or the “Companyˮ) is

pleased to announce the results of a Feasibility Study (“FSˮ or the “ Feasibility Studyˮ) prepared in

accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101ˮ) at

its 100%-owned Black Pine Oxide Gold Project (“Black Pineˮ or the “Projectˮ) in southern Idaho, USA.

The Feasibility Study establishes Black Pine as a large -scale, long-life oxide gold development project

based on a technically straightforward, open-pit, run-of-mine (“ROMˮ) heap-leach operation requiring no

ore crushing, screening or agglomeration. The FS supports average annual payable gold (“Auˮ) production

of 202,000 troy ounces (“ozˮ) in Years 1-5 from a 4.04 million oz Au Probable Mineral Reserve, with an

initial capital cost1 of US$411.4 million and strong economic returns across a broad range of gold prices.

The Feasibility Study assumes a base case gold price of $3,250/oz Au. All figures in this news release are

stated in United States dollars (“$ˮ or “US$ˮ).

2026 Black Pine Feasibility Study Highlights

Large-scale production: 16-year mine-life with an average annual payable production of 202,000 oz Au in

Years 1-5, at an average grade of 0.35 grams per tonne gold (“g/t Auˮ), including peak annual production

of 277,400 oz Au in Year 5; and average annual payable production of 176,700 oz Au over life-of-mine

(“LOMˮ), including peak LOM annual production of 294,600 oz Au in Year 13.

Probable Mineral Reserve containing 4.04 million oz Au: 433.3 million tonnes at a grade of 0.29 g/t Au,

supporting the planned 16-year mine-life.

Capital-efficient development: The Project has an estimated initial capital cost of $411.4 million for a

conventional ROM open-pit heap-leach operation. The ratio of the Projectʼs base- case after-tax Net

Present Value (“NPVˮ)(5%) to initial capital ratio is 5.8.

Competitive operating costs projected: LOM cash costs2 and all-in sustaining costs (“AISCˮ) of $1,388/oz

Au and $1,566/oz Au, respectively.

Robust projected Project returns: At the base case gold price of $3,250 /oz Au, the Feasi bility Study

estimates an after-tax NPV(5%) of $2.397 billion, after-tax Internal Rate of Return (“IRRˮ) of 60.5% and

after-tax payback of initial capital of 2.0 years for the Project.

Black Pine generates strong projected economics across a broad range of gold prices: At $4,500/oz Au,

the Project is estimated to generate an after-tax NPV(5%) of $4.336 billion (IRR of 104.3%) with a payback

of 1.2 years. At a lower gold price, of $2,500/oz Au, the Feasibility Study continues to project positive

economics, including an after-tax NPV(5%) of $1.215 billion (IRR of 33.4%) with a payback of 3.4 years.

Jon Gilligan, President and CEO of Liberty Gold commented:

“Our Feasibility Study on Black Pine, completed ahead of schedule and less than 2 -years after the

Preliminary Feasibility Study, confirms the opportunity to build a large-scale, long-life operation with strong

economics and a technically straightforward development path. This is an important milestone for Liberty

G o l d , r e i n f o r c i n g o u r c o n f i d e n c e i n B l a c k P i n e ʼ s a b i l i t y t o g e n e r a t e l o n g-term value for shareholders,

stakeholders and local communities, representing an important step in advancing the Companyʼs

development strategy.

"Black Pine has the scale, production profile and capital efficiency to support a pathway to becoming a

significant U.S. gold producer in the near term. Importantly, the Feasibility Study demonstrates substantial

projected free cash flow generation with robust economics across a broad range of gold prices. The NPV-

to-initial-capital ratio of approximately 9 times and a payback of just over one year at current gold pricing

of over $4,000/oz, are competitive metrics in the gold development space today.

"The proposed development of Black Pine anticipates supporting approximately 300 long-term jobs and

Liberty Gold looks forward to continuing its engagement with local communities and state officials. With

the Feasibility Study now complete and permitting ongoing, our focus has shifted to detailed engineering,

planning, and other activities required to support execution readiness and a potential construction

decision."

Project Description

Black Pine is a large, Carlin-style, sedimentary rock hosted oxide gold system located in Cassia and Oneida

counties, southern Idaho, USA , with site access directly off the I -84 highw ay. Black Pine is a past -

producing open-pit, ROM heap leach mine, active from 1991 to 1997, when Pegasus Gold Corp. produced

434,800 ounces of gold and 198,000 ounces of silver (“Agˮ) from five open pits. Road access is well

established, with up to 9.9 megawatts of grid power available at site, sufficient for the Project requirements.

Additionally, Liberty Gold has secured sufficient existing water rights in the basin to support the Project.

Liberty Gold holds a 100% ownership interest in the federal lode claims and state minerals lease that host

the Mineral Reserve at Black Pine. The Project is subject to a 0.5% net smelter return royalty (“NSRˮ) in

favour of Wheaton Precious Metals Corp., with a 50% buyback right in favor of Liberty Gold for $3.6 million

(assumed to be exercised in the economic analysis), a 0.25% NSR on certain private mineral lands, and a

5% NSR payable to the State of Idaho on production from the state minerals lease.

Mining

The FS utilizes conventional open pit mining with mine designs generated by AGP Mining Consultants Inc.

(“AGPˮ). The open pits include the larger Discovery and Rangefront pits, together with the smaller CD, E, F,

J and M pits. Average annual total material movement over the 16-year mine life is approximately 64 million

tonnes, at a favourable strip ratio of 1.34:1 (waste:ore).

Two mining fleets are planned to provide operating flexibility across the larger main pits and the smaller

satellite pits. The FS has adopted a full OEM contract for mobile mine equipment maintenance and repair

for the first five years of operations with phased in-sourcing thereafter. The smaller mining fleet is assumed

to be supplied and operated by a mining contractor.

News Release

All mining is conducted with at least 50 feet of freeboard above the water table, and all open pits are

considered dry and are not expected to require dewatering or depressurization.

Processing and Metallurgy

Gold will be recovered using ROM heap leaching with no crushing, screening or agglomeration. Ore will

be truck-stacked onto a phased heap leach facility followed by conventional cyanide leaching and

processed through an adsorption, desorption and recovery (“ADRˮ) plant which will produce gold and silver

doré bars that will be shipped off-site for further refining. The FS estimates an overall LOM gold recovery

of 70.2%, based on recovery equations developed for the modeled metallurgical domains. Selected lower

recovery ore will be stockpiled by metallurgical type for subsequent placement on the heap leach facility.

Black Pine has been the subject of extensive metallurgical testwork, including eight metallurgical programs

completed since 2019 using bulk samples and large-diameter PQ core, at Kappes, Cassiday & Associates

in Reno, Nevada. Additional programs are ongoing including the bulk sample column leach testing from

surface ores collected across the deposit and sample testing from sonic drill holes in the Legacy Heap

Leach Facility (“LHLFˮ) to evaluate its economic potential.

Capital and Operating Costs

Initial capital to develop Black Pine is estimated at $411.4 million, comprising process and site infrastructure,

heap leach facilities, mine capital (including initial deposits for mining equipment), pre-production activities,

engineering, procurement and construction management (“EPCMˮ), contingency and ownerʼs costs. The

FS assumes all mining equipment is leased at prevailing commercial rates.

In addition to initial capital, the FS estimates $254.0 million of sustaining capital over the 16-year mine life.

Reclamation and closure costs are estimated at $160.1 million.

Total life-of-mine capital, including initial, sustaining and closure expenditures , is estimated at $825.5

million. See Table 3 below.

Environmental, Permitting and Community

Black Pine is currently advancing through federal and state permitting as a FAST-41 Covered Project, based

upon the Companyʼs 2026 MPO.

News Release

Page 8 of 14

The U.S. Forest Service published a Notice of Intent on April 3, 2026, formally initiating public scoping and

preparation of the Environmental Impact Statement (“EISˮ) under the National Environmental Policy Act

(“NEPAˮ).

Liberty Gold has maintained an active stakeholder and community outreach program since 2019, including

regular engagement with local municipalities, county commissioners, the Idaho Legislature, regulatory

agencies and community groups. No material environmental issues have been identified to date that are

expected to preclude securing the permits and authorizations required to develop Black Pine.

Further Opportunities

The FS establishes a development case for Black Pine while identifying opportunities for further evaluation:

• Near-term finalization of a Silver Resource: Silver resources have been estimated at the Discovery

and M Zones, and work is ongoing for the remainder of the deposit, with further details to be

provided in the FS. No silver mineral reserve or silver production is included in the FS.

• Resource conversion and growth: Possible conversion of the Inferred Mineral Resource of 58.4

million tonnes at an average grade of 0.14 g/t Au and containing 171 thousand oz of potentially

recoverable gold to the Indicated category; continued resource growth from step-out drilling around

known mineralized centres; and, e valuation of additional high-priority targets across the mineral

lease area of ~ 70 square kilometers. Inferred Mineral Resources are considered too speculative

geologically to have the economic considerations applied to them that would enable them to be

considered Mineral Reserves and there is no certainty that further exploration will result in the

conversion of Inferred Mineral Resources to Indicated Mineral Resource.

• 2026 Drilled to Measured (“DtMˮ) program: This yearʼs drill program has been designed to upgrade

the mineral resource classification from Indicated to Measured for the early years of the mine plan

presented in the FS. Drilling is expected to be completed later this year and with final assay results

following. This program is intended to significantly derisk the ore supply during operational start-up

and over the initial capital payback period.

• Mine and heap optimization: Continued optimization of mine planning, mining rates, stacking rates,

cut-off grade strategy, stockpiling, haulage and heap leach facility design and phasing.

Pathway to a Construction Decision

Liberty Gold continues to advance Black Pine toward a potential construction decision through detailed

engineering, procurement, financing and execution readiness, while permitting continues under the

established FAST-41 schedule. The Company has recently selected M3 Engineering & Tech nology

Corporation and NewFields Companies LLC as principal engineering partners for the detailed engineering

phase and this work has commenced.

The recommended work program is proposed in two phases:
