News Release Page 2 of 14 The development configuration evaluated in the FS is aligned with the Company's 2026 Mine Plan of Operations (“MPOˮ). The Feasibility Study does not replace the MPO that forms the basis for permit applications currently under review by the applicable regulatory agencies but rather incorporates potential future feasibility-level optimizations and refinements. This news release should be read in combination with the F easibility Study presentation available at https://libertygold.ca/wp-content/uploads/Black_Pine_FS.pdf 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. 2 Cash Costs are non-GAAP financial measure that does not have a standardized meaning under IFRS. See “Non-GAAP Measures and Other Financial Measuresˮ below.

News Release Page 3 of 14 "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."

News Release Page 5 of 14 Strong Economics Across a Broad Range of Gold Prices Black Pine demonstrates significant upside leverage and downside resilience within the range of gold prices evaluated. An analysis of the FS base case illustrates the Project's sensitivity to gold price, with all other material assumptions remaining constant, as summarized in Table 2 below. Table 2: After-Tax NPV (5%), IRR and Payback Sensitivity to Gold Price Gold Price ($/oz) $2,500 $3,000 $3,250 (Base Case) $3,500 $4,000 $4,500 After-Tax NPV(5%) ($M) $1,215 $2,006 $2,397 $2,786 $3,562 $4,336 After-Tax IRR (%) 33.4% 51.6% 60.5% 69.4% 87.0% 104.3% After-Tax Payback (years) 3.4 2.3 2.0 1.7 1.4 1.2 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.
Page 6
News Release Page 6 of 14 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.
Page 8
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:
Page 9
News Release Page 9 of 14 • Phase 1 – Engineering, Procurement and Execution Readiness : Complete detailed engineering through Liberty Goldʼs appointed engineering partners, continue permitting activities, finalize the execution schedule and control budget, undertake procurement of long -lead equipment, and advance the commercial and execution planning activities required to support a future construction decision. • Phase 2 – Construction, Commissioning and Ramp -Up: Subject to formal approvals, c omplete project construction and mine development, install processing and site infrastructure facilities, recruit and train the operating workforce, and commission the operation for commercial production. Black Pine Mineral Reserve Estimate The FS includes an updated Mineral Reserve estimate, with an effective date of August 1, 2026. The FS establishes a 4.04 million oz Au Probable Mineral Reserve, comprising 433.3 million tonnes grading 0.29 g/t Au. The Probable Mineral Reserve consists of Indicated blocks above a cut -off grade of 0.05 g/t recoverable Au. There are no Measured Min eral Resources at Black Pine and, accordingly, no Proven Mineral Reserves.

Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources and Probable Reserves The information, including any information incorporated by reference, and disclosure documents of Liberty Gold that are filed with Canadian securities regulatory authorities concerning mineral properties have been prepared in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of United States securities laws. Without limiting the foregoing, these documents use the terms “measured resources”, “indicated resources”, “inferred resource s” and “mineral reserves”. These terms are Canadian mining terms as defined in, and required to be disclosed in accordanc e with, NI 43-101, which references the guidelines set out in the CIM Definition Standards, adopted by the CIM Council, as amended. However, these standards differ significantly from the mineral property disclosure requirements of the United States Securities and Exchange Commission (the “ SEC”) in Regulation S -K Subpart 1300 (the “ SEC Modernization Rules ”) under the United States Securities Act of 1934, as amended. The Company does not file reports with the SEC and is not required to provide disclosure on i ts mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards.
