WESTHAVEN FILES TECHNICAL REPORT IN SUPPORT OF UPDATED PRELIMINARY ECONOMIC

ASSESSMENT FOR THE SHOVELNOSE GOLD PROJECT, BRITISH COLUMBIA

______________________________________________________________________________________________

Vancouver, B.C. – April 17th, 2025 – Westhaven Gold Corp. (TSX-V:WHN) (“Westhaven”) announces that

it has filed an independent technical report pursuant to National Instrument 43-101 - Standards of

Disclosure for Mineral Projects (“NI 43-101”) supporting the Updated Preliminary Economic Assessment

(the “Updated PEA”) for its 100% owned Shovelnose Gold Project, under the Westhaven profile on Sedar+

(www.sedarplus.com). The Company’s news release dated March 3, 2025 summarizes the positive results

of the Updated PEA for the Shovelnose Gold Project, located within the prospective Spences Bridge Gold

Belt, bordering the Coquihalla Highway approximately 30 kilometres south of Merritt, British Columbia.

The Technical Report, titled “Updated Preliminary Economic Assessment and Mineral Resource Estimate

of the Shovelnose Gold Project, British Columbia” was prepared by James L. Pearson, P.Eng., D. Grant

Feasby, P.Eng., Yungang Wu, P.Geo., Antoine Yassa, P.Geo., Brian Ray, P.Geo., Jarita Barry, P.Geo.,

Alexander Partsch, P.Eng., Dipl.-Ing, MBA, William Stone, Ph.D., P.Geo., and Eugene Puritch, P.Eng., FEC,

CET of P&E Mining Consultants Inc., Brampton, Ontario (“P&E”), all Independent Qualified Persons as

defined by NI 43-101. The technical report includes descriptions of important assumptions, and the

justifications for them, made by the Qualified Persons who prepared the Updated PEA, and upon which

the Updated PEA results are based. The Updated PEA is preliminary in nature and includes Inferred

Mineral Resources that are considered too speculative geologically to have the economic considerations

applied to them that would enable them to be classified as Mineral Reserves, and there is no certainty

that the Updated PEA will be realized. Mineral Resources are not Mineral Reserves and do not have

demonstrated economic viability. There is no guarantee that Westhaven will be successful in obtaining

any or all of the requisite consents, permits or approvals, regulatory or otherwise, for the Shovelnose

Gold Project to be placed into production. The Updated PEA has an effective date of February 28, 2025,

and the report is dated April 17th, 2025. Mr. Puritch has reviewed and approved the technical contents of

this news release.

The technical report can also be found on the Westhaven website (https://www.westhavengold.com/ ).
