WESDOME DRILLING CONFIRMS CONTINUITY OF PRESQU'ILE ZONE AND PREPARES FOR EXPLORATION RAMP DEVELOPMENT AT KIENA MINE

Wesdome Gold Mines Ltd. has released 2023 surface exploration drilling results from the Presqu'ile zone, located 1.3 kilometres northwest of the company's 100-per-cent-owned Kiena mine complex in Val d'Or, Que.

Recent drilling at Presqu'ile is part of a continuing exploration program focusing on near-surface gold potential along strike from Kiena that remains underexplored. Drilling results from the Shawkey and Dubuisson zones, located farther to the east along strike, were released earlier this year (see May 23, 2023, press release). Continuing drilling highlights the potential of this area to add to the existing resource base proximal to mine infrastructure and remains a priority for the company.

Highlights of recent infill drilling are listed in an attached table. Assay results for nine of 32 diamond drill holes planned are pending:

• Hole PR-23-070 -- 32.5 grams per tonne gold over 3.0 metres core length (30.0 g/t Au capped, 2.9 m true width) in the PR-2A zone;
• Hole PR-23-084 -- 14.0 g/t Au over 5.3 m core length (14.0 g/t Au capped, 4.0 m true width) in the PR-2 zone;
• Hole PR-23-058A -- 9.31 g/t Au over 4.6 m core length (9.31 g/t Au capped, 4.3 m true width) in the PR-2 zone.

All assays are capped at 90 g/t Au. True widths are estimated based on three-dimensional model construction.

Anthea Bath, president and chief executive officer, commented: "We are pleased with the recent surface drill results that confirm continuity of mineralization at Presqu'ile. The Presqu'ile zone is just one of several zones having the potential to offer a supplementary source of mill feed near surface or in the upper mine area for the underutilized Kiena mill. Recent drilling results from the Shawkey and Dubuisson zones, both adjacent to the existing 33-level track drift development that extends over three kilometres east of the Kiena mine shaft, further reinforces the potential of this area. As our exploration continues and the refinement of the geologic model increases, we are confident we will identify more zones of gold mineralization accessible from 33 level, as well as additional down-plunge extensions similar to the Kiena Deep zone.

"Recent drilling supports the decision to proceed with the exploration ramp from surface later this year to further assess the continuity of the mineralization and test the down-plunge extension of the deposit. The excavation of the ramp is expected to proceed in Q4 2023, once required permits are secured. This ramp can also be integrated with Kiena's existing underground ramp network, providing additional access to surface for ongoing operations and future mining of deposits, such as Dubuisson, from 33 level further to the east."

Since 2020, drilling at Presqu'ile has identified five gold-rich zones crosscutting mafic rocks (zones PR-1, 2 and 2A) and ultramafic rocks (zones PR-3 and 4). PR-1 and PR-2A are parallel to each other, trending east-west and dipping north, while PR-2 strikes southeast-northwest and crosscuts the east-west zones. Gold mineralization is associated with traces to 5 per cent disseminated sulphides (pyrite, pyrrhotite, chalcopyrite, sphalerite and galena) and local gold grains occurring in quartz-chlorite-carbonate or quartz (grey) vein contacts as well as in moderately to strongly chloritized and biotitized host rocks.

The 2023 surface drilling program, which is expected to be completed by the end of September, was designed to increase the size and confidence in the mineral resources for zones PR-1, 2 and 2A. The 2023 drilling program confirmed not only the continuity of the gold mineralization at Presqu'ile and the validity of the geologic model, but also the potential for down-plunge extensions toward east of zones PR-2 and PR-2A. Both zones are interpreted as excellent targets for a follow-up drilling program from surface or from underground with development of an exploration ramp.

Presqu'ile has a mineral resource estimation of 138,000 tonnes grading 8.2 g/t Au totalling 37,000 ounces of gold as indicated mineral resources and 202,000 tonnes grading 7.4 g/t Au totalling 48,000 ounces of gold as inferred mineral resources from the three lenses (PR-1, PR-2 and PR-2A) as of Dec. 31, 2022.

Technical disclosure

The technical and geoscientific content of this release has been compiled and reviewed by Denys Vermette, PGeo (OGQ No. 564), exploration manager of the company, a qualified person as defined in National Instrument 43-101 --Standards of Disclosure for Mineral Projects.

Sample preparation and analytical work were performed by ALS Minerals of Winnipeg, Man., a certified commercial laboratory (accredited lab No. 689). Assaying comprised fire assay methods with an atomic absorption finish. Any sample assaying greater than three g/t Au was rerun by the fire assay method with gravimetric finish, and any sample assaying greater than 10 g/t Au was rerun with the metallic sieve method. In addition to laboratory internal duplicates, standards and blanks, the geology department inserts blind duplicates, standards and blanks into the sample stream at a frequency of one in 20 to monitor quality control.
