Westhaven Reports South Zone Resource Infill Drilling Continues to Confirm Continuity of High-Grade Gold and Silver Mineralization Including 27.51m Grading 14.47 g/t Au & 52 g/t Ag Shovelnose Gold Property, Southern British Columbia

Westhaven Gold Corp. (WHN) has released the fourth batch of assay results from its 35,000-meter resource infill program at the South Zone deposit on the Shovelnose property. The company reports that the program is now 66% complete, with 23,184 meters drilled of the total 35,000-meter target. To support the remaining work, a fifth exploration rig has been mobilized to drill an additional 15,000 meters of exploration holes.

The latest results confirm the continuity of Vein Zones 1, 2, and 3. A significant high-grade intercept was identified in hole SNR26-113, which returned a single-assay high of 0.52 meters at 200 g/t Au and 141 g/t Ag. This high-grade hit is located at the northern extent of the current zone, suggesting potential extensions into the Alpine target area.

Key intercepts from the latest batch include:

• SNR26-99: 27.51 meters at 14.47 g/t Au and 52.3 g/t Ag from 274.27 meters downhole, including 2.07 meters at 107.5 g/t Au and 334 g/t Ag.
• SNR26-114: 30.76 meters at 3.31 g/t Au.
• SNR26-99 second zone: 16.80 meters at 4.63 g/t Au.
• SNR26-90: 11.65 meters at 5.20 g/t Au.
• SNR26-97: 13.50 meters at 2.98 g/t Au.
• SNR26-102: 5.20 meters at 9.19 g/t Au.

Westhaven Gold Corp. (WHN) is a well-funded explorer with a defined resource and a Preliminary Economic Assessment (PEA), currently advancing toward a Preliminary Feasibility Study (PFS). The company’s 2026 program is 100% funded by Dundee’s initial $30M commitment.

The recent news involves routine infill drilling. The intercepts confirm the grade and width of a known deposit that already underpins a $454M NPV. The market had already priced in the deposit’s robustness following the May 2026 high-grade infill releases, which included intervals such as 54m @ 8.99 g/t.

The stock has been range-bound between $0.26 and $0.34 since May. These results do not change the resource thesis materially, nor do they surprise positively relative to prior intervals.

The release is considered positive but routine. While the highest single assay may generate retail interest, it is not considered institutional-grade.

Westhaven Gold Corp. (TSX-V:WHN, OTCQB:WTHVF) is a junior explorer focused on the Spences Bridge Gold Belt in southern BC. Its flagship Shovelnose project hosts a low-sulphidation epithermal gold-silver system. A preliminary economic assessment (PEA) for the project indicates a production rate of 56 koz Au/year over an 11-year life of mine, with an after-tax net present value of $454M at a 6% discount rate and an internal rate of return of 43.2%.

The company’s resource estimates include an indicated category of 3.77 Mt grading 6.0 g/t Au and 31 g/t Ag, containing 737 koz Au. The inferred category comprises 3.20 Mt grading 3.6 g/t Au and 28 g/t Ag, containing 371 koz Au.

Westhaven has entered into a strategic earn-in agreement with Dundee Corporation, which may earn up to 60% of the project by funding up to $85M in stages. The Phase 1 commitment requires $30M, including 50,000m of drilling. Westhaven remains the operator until the 50% earn-in threshold is reached. As of Q1 2026, the company held a cash position of approximately $3.4M, with fully diluted shares of ~314M, a market cap of ~$75M, and insider ownership of 16%.
