Westhaven Gold Corp. Reports Assay Results From South Zone Resource Infill Drilling At Shovelnose Gold Property
Westhaven Gold Corp. has reported the fourth batch of assay results from the ongoing 35,000m resource infill drilling program, presently supported by four drill rigs at the South Zone gold and silver deposit on the Shovelnose gold property in southern British Columbia. 35,000m resource infill drilling is 66% complete with four active drills on the South Zone deposit. New highlight assays include: 27.51m grading 14.47 g/t Au and 52.3 g/t Ag; 30.76m grading 3.31 g/t Au and 21.3 g/t Ag; 0.52m grading 200 g/t Au and 141 g/t Ag; 16.80m grading 4.63 g/t Au and 19.6 g/t Ag; 11.65m grading 5.20 g/t Au and 15.9 g/t Ag. A fifth, exploration focused drill is now operational on the property targeting potential resource growth through a 15,000m exploration drilling program. Highlight results reported include intersections of 16.80m grading 4.63 g/t Au and 19.6 g/t Ag and 27.51m grading 14.47 g/t Au and 52.3 g/t Ag from drill hole SNR26-99 and 30.76m grading 3.31 g/t Au and 21.3 g/t Ag from drill hole SNR26-114. Additionally, hole SNR26-113, testing the northern extent of the deposit returned a 0.52m section grading 200 g/t Au and 141 g/t Ag, representing the highest single assay reported to date from the infill program. The 2026 field program has also entered a new phase of potential discovery and resource growth with a fifth diamond drill actively testing exploration targets on Shovelnose as part of a 15,000m exploration drilling program expected to continue through mid-December. This work is being funded under a strategic earn-in agreement with Dundee Corporation, whereby Dundee may earn up to a 60% interest in Westhaven's four Spences Bridge Gold Belt properties through up to CAD 85,000,000 in staged project expenditures. Under the first phase, Dundee has committed a minimum of CAD 30,000,000, inclusive of a fully funded 50,000m resource infill and exploration drill program and ongoing pre-feasibility study work at Shovelnose. Assay results from the ongoing 35,000m resource infill drilling program at the South Zone deposit continue to show excellent continuity of mineralization in each of Vein Zones 1, 2 and 3. Results have been received from an additional 14 infill drill holes and are reported in Table 1. The resource drilling program has been designed to infill the deposit at nominal 25m centres with results to be included in an updated mineral resource estimate to support a pre-feasibility study targeting completion in Second Half 2027. To date, 73 drill holes (23,184m) have been completed representing approximately two-thirds of the planned program metreage. Selected assay highlights include: SNR26-90: 11.65m grading 5.20 g/t Au & 16 g/t Ag from 79.85m downhole; SNR26-97: 13.50m grading 2.98 g/t Au & 10 g/t Ag from 132.00m downhole; SNR26-99: 16.80m grading 4.63 g/t Au & 20 g/t Ag from 133.25m downhole; and 27.51m grading 14.47 g/t Au & 52 g/t Ag from 274.27m downhole; including 2.07m grading 107.5 g/t Au and 334 g/t Ag from 283.12m; SNR26-102: 5.20m grading 9.19 g/t Au & 36 g/t Ag from 56.00m downhole; SNR26-113: 0.52m grading 200 g/t Au & 141 g/t Ag from 178.86m downhole; SNR26-114: 30.76m grading 3.31 g/t Au & 21 g/t Ag from 236.24m downhole. Assay intervals noted above represent downhole intersections, not true widths. True widths can be estimated at approximately 70-80% of the reported intervals. Most core samples consist of halved drill core cut by manual sawing using industry standard core saws. 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 bar-coded 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% passing a 2mm (Tyler 9 mesh, US Std. No.10) screen. A split of 250g is taken and pulverized to better than 85% passing a 75-micron (Tyler 200 mesh, US Std. No. 200) screen. Further analytical and assay procedures are conducted in ALS’s North Vancouver facility. A 0.75g subsample of the pulverized split is subjected to four acid digestion and analyzed via ICP-MS (method code ME-MS61m (+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 (30g sample size) or Au-ICP22 (50g sample size). Samples returning gold values over 10ppm are subjected to over-limit check assays using fire assay and a gravimetric finish (method code Au-GRA21 and a 30g sample size, or Au-GRAV22 and a 50g sample size). The switch to 50g aliquots applies to 2026 resource infill drill holes starting at, and including, SNR26-98. Other over-limit elements may also be subjected to ore grade analyses which vary depending on the element of interest. ALS’s facilities are accredited to the ISO/IEC 17025 standard for gold assays, and all analytical methods include quality control materials at set frequencies with established data acceptance criteria. QA/QC incorporates the laboratory’s internal quality assurance controls as well as Westhaven’s field controls, including the insertion of quarter core duplicates, certified reference materials and blanks, each at a rate of roughly one per 20-25 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 ongoing QA/QC programs are consistent with industry best practices and include auditing of all exploration data. Any significant changes will be reported when available. Reported intervals are at least 2m in length with a 1 g/t Au cut-off for individual samples and no more than 3m contiguous metres dilution. Or less than 2m in length with an individual sample returning >10 g/t Au. On February 23, 2026, Westhaven closed a strategic earn-in agreement with Dundee Corporation, whereby Dundee may earn up to a 60% interest in Westhaven's four Spences Bridge Gold Belt properties through up to CAD 85,000,000 in staged project expenditures. Under the first phase, Dundee has committed a minimum of CAD 30,000,000, inclusive of a fully funded 50,000m drill program and pre-feasibility 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.
