Second drill mobilized at Shovelnose Westhaven is also pleased to confirm the on-schedule mobilization of a second drill to the Shovelnose property, in support of the 50,000-metre 2026 drill program announced by the company on Feb. 17, 2026. The initial phases of this $20-million program will focus on continued resource expansion and infill drilling at the South Zone gold deposit. The program is expected to ramp up to four drills by June, 2026, with resource and exploration drilling to continue through to mid-December. 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 approximately 60,263 hectares within four gold properties spread along this underexplored belt. The Shovelnose gold project is the most advanced property, with a recently updated 2025 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 a 43.2-per-cent internal rate of return (base-case assumptions of $2,400 (U.S.) per ounce gold, $28 (U.S.) per ounce silver and a Canadian/U.S.-dollar exchange rate of $1 (Canadian) equals 72 U.S. cents). On Feb. 23, 2026, Westhaven closed a strategic earn-in agreement with Dundee Corp., whereby Dundee may earn an up-to-60-per-cent interest in Westhaven's four Spences Bridge gold belt properties through up to $85-million (Canadian) in staged project expenditures. Under the first phase, Dundee has committed a minimum of $30-million (Canadian), inclusive of a fully financed 50,000-metre drill program at Shovelnose in 2026. The agreement allows for the accelerated exploration and evaluation of one of Canada's most compelling, undeveloped, high-margin gold and silver assets.
