Westhaven Gold's Shovelnose Infill Campaign Validates South Zone Continuity Ahead of Prefeasibility

Westhaven Gold Corp. ($WHN) has built one of the more closely watched gold-silver drill programs in southern British Columbia's Spences Bridge Gold Belt, underpinned by a fully funded CDN$85 million earn-in commitment from Dundee Corporation ($DC.A). The program's early-2026 infill phase is now generating results that corroborate the structural thesis behind that deal.
Hole SNR26-73 returned 14.00 g/t gold and 78 g/t silver over 33.0 metres (163–196m depth), with a high-grade core of 47.56 g/t gold and 229 g/t silver over 8.12 metres — the intercept that anchors the current release. A companion hole, SNR26-74, added 9.51 g/t gold and 44 g/t silver over 24.63 metres, reinforcing lateral continuity within the South Zone deposit. Both results sit within the 462 g-m gram-metre range for the 33-metre interval — solid for an infill program where the objective is deposit definition rather than discovery.
Dundee's earn-in structure is notable context. Under the February 2026 agreement, Dundee earns up to 60% of Westhaven's four Spences Bridge Gold Belt properties by spending up to CDN$85 million in staged expenditures. The first phase locks in a minimum CDN$30 million, covering a fully funded 50,000-metre drill program and prefeasibility work at Shovelnose. As of the release date, 11,514 metres across 40 holes have been completed — roughly 33% of the planned mineral resource infill yardage — with four drills active on site as of May 15, 2026.

The program's explicit goal is inclusion of updated intercepts in a revised mineral resource estimate, which feeds directly into the prefeasibility study. For the Spences Bridge Gold Belt, consistent infill grades across multiple holes — rather than isolated high-grade spikes — are what advance a project toward an economic study. The current data set, with broad intervals maintaining double-digit gold grades, supports that trajectory.
