Westhaven hits 10.04 m grading 12.18 g/t Au & 103 g/t Ag at Shovelnose
Drill hole SNR26-117 returned 10.04m grading 12.18 g/t Au and 103 g/t Ag, extending high-grade gold and silver mineralization below the deepest mining stopes proposed in Westhaven’s 2025 preliminary economic assessment (“PEA”).
Drill hole SNR26-110 returned 37.34m grading 6.24 g/t Au and 55 g/t Ag, confirming thick, high-grade gold and silver mineralization at the southeastern margin of the deposit.
35,000m resource infill drilling program is >76% complete, with four active drills on the South Zone deposit
VANCOUVER, British Columbia, Aug. 20, 2026 (GLOBE NEWSWIRE) -- Westhaven Gold Corp. (TSX-V: WHN) (OTCQB: WTHVF) (FRA: 1W5) (“Westhaven” or the “Company”) is pleased to report the fifth 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.
Ken Armstrong, President and CEO of Westhaven, commented:
“This latest batch of assays from ongoing resource infill drilling includes two drill holes that confirm the presence of thick, high-grade gold and silver mineralization both below and at the southeastern margin of the South Zone deposit. Drill hole SNR26-117 is of particular importance as its 10m interval grading 12.18 g/t Au and 103 g/t Ag has extended mineralization below the deepest proposed mining stopes in Westhaven’s 2025 preliminary economic assessment. Similarly, SNR26-110, returning 37.34m grading 6.24 g/t Au and 55 g/t Ag, has confirmed thick, high-grade mineralization at the southeastern edge of the deposit. Follow up drilling is required in the vicinity of both of these holes where there is clearly potential to increase contained ounces in the South Zone deposit.”
Highlight results reported today include intersections of 37.34m grading 6.24 g/t Au and 55 g/t Ag (SNR26-110) in the southeastern part of the South Zone deposit, and 10.04m grading 12.18 g/t Au and 103 g/t Ag (SNR26-117) located below the proposed mine development in Westhaven’s 2025 PEA.
In addition to the infill resource drilling, the 2026 field program continues with exploration drilling and surface field work within the greater Shovelnose property area and is expected to continue through mid-December. This work is being funded under a strategic earn-in agreement with Dundee Corporation (“Dundee”), whereby Dundee may earn up to a 60% interest in Westhaven's four Spences Bridge Gold Belt properties through up to CDN$85,000,000 in staged project expenditures. Under the first phase, Dundee has committed a minimum of CDN$30,000,000, inclusive of a fully funded 50,000m resource infill and exploration drill program and ongoing pre-feasibility study (“PFS”) work at Shovelnose.
South Zone Mineral Resource Infill Drilling
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 6 infill drill holes and are reported in Table 1. Earlier assays from the 2026 infill drilling program can be found Westhaven news releases dated: May 7, linked here , May 26, linked here , July 7, linked here , and July 28, linked here . 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 PFS targeting completion in H2 2027. To date, 85 drill holes (26,581m) have been completed representing approximately three-quarters of the planned program metreage.
Table 1 shows assay results, including drill hole locations and orientations, and is also linked here . Reported assay intervals represent downhole intersections, not true widths. True widths can be estimated at approximately 70-80% of the reported intervals.
Figure 1 shows the locations of the drill holes reported in this news release, as well as the other holes completed in 2026, the planned 2026 drill collar locations and the drill collars of pre-2026 drilling of the South Zone.
Figure 2 presents a South Zone cross-section highlighting drill hole SNR26-117, and Figure 3 presents a South Zone cross-section highlighting drill hole SNR26-110. The sections are viewed to the northwest (310°) and illustrate strong continuity of mineralization hosted within structurally controlled quartz veins and hydrothermal breccia zones.
Sampling, Laboratory Analyses and Quality Assurance/Quality Control (QA/QC)
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.
