WESTHAVEN COMMENCES AIRBORNE GEOPHYSICAL SURVEYS AT ITS SHOVELNOSE GOLD AND SILVER PROJECT, SOUTHERN BRITISH COLUMBIA

Precision GeoSurveys Inc., based in Langley, B.C., has commenced helicopter-borne high-resolution magnetic, radiometric and VLF-EM surveys at Westhaven Gold Corp.'s Shovelnose gold and silver property located in the Spences Bridge gold belt, Southern British Columbia.

These surveys are being funded under a strategic earn-in agreement with Dundee Corp., whereby Dundee may earn up to a 60-per-cent interest in Westhaven's four Spences Bridge gold belt properties through up to $85-million in staged project expenditures. Under the first phase, Dundee has committed a minimum of $30-million, inclusive of the geophysical surveys announced today as well as a fully financed 50,000-metre drill program and prefeasibility work that are presently under way at Shovelnose.

The airborne geophysical surveys are part of an integrated 2026 exploration program at Shovelnose and will collect approximately 3,800 line kilometres of data over mineral claims that were acquired by Westhaven in 2024. The core of the Shovelnose property, including the South zone, FMN and Franz gold deposits, was previously flown by Precision in 2018, using magnetic/radiometric technology and specifications equivalent to the current survey. Data from the original survey work has been instrumental in understanding the geology, interpreting structures and assisting in exploration targeting. The new survey data will be integrated with the earlier survey information, as well as results from property-wide geochemical sampling programs completed over the last three years, which suggest potential for additional occurrences of low-sulphidation epithermal systems within the expanded project area, including silicified and clay altered volcanic rocks located approximately 15 km southeast of the South zone, where float, subcrop and outcrop rock grab samples collected in 2025 returned from background levels up to 2.45 grams per tonne Au (gold) (96.2 g/t Ag (silver)). Please see Westhaven's news release dated Jan. 26, 2026, for details.

Data collection is expected to be completed by the end of May, with final data processing and reporting to follow by mid-summer, in time to help guide exploration drilling later this year.

About Westhaven Gold Corp.

Westhaven is a gold and silver focused exploration and development company targeting low-sulphidation, high-grade, epithermal style gold and silver mineralization within the Spences Bridge gold belt in Southern British Columbia. Westhaven controls about 60,263 hectares within four properties spread along this underexplored belt.

The Shovelnose gold and silver project is the most advanced property, with a 2025 updated preliminary economic assessment that validates the project's potential as a robust, low-cost and high-margin 11-year underground gold mining opportunity with average annual life-of-mine production of 56,000 ounces gold and 313,000 ounces silver with a $454-million after-tax net present value (at a 6-per-cent discount rate) and 43.2-per-cent IRR (internal rate of return) (base case parameters of $2,400 (U.S.) per ounce gold, $28 (U.S.) per ounce silver and Canadian-dollar/U.S.-dollar exchange rate of $1.00 (Canadian):72 U.S. cents).

On Feb. 23, 2026, Westhaven closed a strategic earn-in agreement with Dundee Corp. whereby Dundee may earn up to a 60-per-cent interest in Westhaven's four Spences Bridge gold belt properties through up to $85-million in staged project expenditures. Under the first phase, Dundee has committed a minimum of $30-million, inclusive of a fully financed 50,000-metre drill program and prefeasibility work at Shovelnose. The agreement allows for the accelerated exploration and evaluation of one of Canada's most compelling, undeveloped, high-margin gold and silver assets.
