WESTHAVEN COMMENCES WINTER DRILL PROGRAM ON THE SHOVELNOSE GOLD PROPERTY

Drilling has commenced on Westhaven Gold Corp.'s 41,634-hectare Shovelnose gold property, situated within the prospective Spences Bridge gold belt (SBGB), 30 kilometres south of Merritt, B.C.

The winter drill program will be testing three target areas: Certes 1, Certes 3 and Corral, with approximately 2,500 metres (m) of drilling in five holes. Certes 1 and 3 are located approximately eight to 10 kilometres (km) southeast of the high-grade South zone deposit (see preliminary economic assessment July 18, 2023). A corridor of mineralization and anomalous pathfinder geochemistry was expanded southeast by surface sampling and drilling in 2024. This corridor may represent single west-northwest-striking structure 13.5 km in length that remains open in all directions.

Preliminary shallow drilling in 2024 at Certes has uncovered a well-preserved epithermal system, now confirmed in the pathfinder geochemistry and TerraSpec (SWIR) analytical work. Certes 3 will be the initial focus of the program, testing down-dip the arsenic and gold-bearing carbonate breccias and quartz veins intersected in hole SN24-425 (that is, 125 ppm (parts per million) arsenic over nine m, 0.69 gram per tonne Au over 1.74 m).

Drilling at Certes 1 will test a subvertical resistivity feature, outlined by the fall 2024 IP survey, immediately north of hole SN24-420 which saw a transition from high level gold pathfinders, mercury and antimony in the first 350 m (that is, 0.44 ppm Hg (mercury) over 119 m) to deeper pathfinders such as arsenic in the bottom 40 m of the hole. Certes 1 is also proximal to mercury-bearing sinter cobbles and boulders found on surface, suggesting the epithermal system is entirely preserved here.

A single hole is also planned at the Corral target, south of Certes. Corral is thought to represent a west-northwest-striking structure subparallel to Certes in an area of anomalous arsenic in outcrop. This hole will target a resistivity feature detected in the same IP survey.

Shovelnose development

An updated mineral resource estimate and preliminary economic assessment for the South zone deposit is expected to be completed in Q1 2025 and will include the Forget Me Not (FMN) and Franz zones, additional discoveries located within the main Vein zone 1 trend.

Qualified person statement

Peter Fischl, PGeo, who is a qualified person within the context of National Instrument 43-101, has read and takes responsibility for this release. Sampling, laboratory analyses and quality assurance/quality control (QA/QC)

Most core samples consist of halved drill core cut by manual sawing. In rare cases, and where required by physical core conditions, manual splitting may be used. Half of the core is retained in the original core box for reference samples and any required future work, including QA/QC. Core samples, controlled by a unique barcoded reference number, are delivered to ALS's Kamloops facility and prepared using the PREP-31 package. Each core sample is crushed to better than 70 per cent passing a two-millimetre (Tyler 9 mesh, U.S. Std. No. 10) screen. A split of 250 g is taken and pulverized to better than 85 per cent passing a 75-micrometre (Tyler 200 mesh, U.S. Std. No. 200) screen. Further analytical and assay procedures are conducted in ALS's North Vancouver facility. A 0.75 g subsample of the pulverized split is subjected to four-acid digestion and analyzed via ICP-MS (method code ME-MS61m (plus Hg)) which reports a suite of 49 elements. All samples are also analyzed for gold by fire assay with an AES finish, method code Au-ICP21 (30 g sample size). Samples returning gold values over 10 ppm are subjected to ore grade check assays using fire assay and a gravimetric finish (method code Au-GRA21 and a 30 g sample size). Other overlimit elements may also be subjected to ore grade analyses which vary depending on the element of interest. QA/QC includes the laboratory's internal quality assurance controls as well as field controls, including the insertion of quarter core duplicates, certified reference materials and blanks, each at a rate of roughly one per 20 to 25 core samples. Additional blanks are inserted following samples with visible gold or significant concentrations of ginguro (fine grained bands of dark gray to black sulphides). QA/QC data are evaluated on receipt for failures and appropriate action is taken if results for duplicates, standards and blanks fall outside allowed tolerances. Westhaven's continuing quality assurance and quality control programs are consistent with industry best practices and include auditing of all exploration data. Any significant changes will be reported when available.

About Westhaven Gold Corp.

Westhaven is a gold-focused exploration company advancing the high-grade discovery on the Shovelnose project in Canada's newest gold district, the Spences Bridge gold belt. Westhaven controls 61,512 hectares (615 square kilometres) with four gold properties spread along this underexplored belt. The Shovelnose property is situated off a major highway, near power, rail, large producing mines and within commuting distance from the city of Merritt, which translates into low-cost exploration.
