Wesdome Drilling Continues to Return High Grades Over Mineable Widths From Recently Discovered Zones Both West and East of the Mine Diorite at the Eagle River Mine

TORONTO, Dec. 11, 2023 (GLOBE NEWSWIRE) -- Wesdome Gold Mines Ltd. (TSX: WDO, OTCQX: WDOFF) ("Wesdome" or the "Company") today announces additional drill results from the recently discovered zone hosted in volcanics west of the mine diorite and additionally from mineralization identified along the eastern margin of the mine diorite at the Company's wholly-owned Eagle River Mine ("Eagle River") in Wawa, Ontario.

Ms. Anthea Bath, President and CEO commented: "Results from ongoing drilling continue to better define and expand the newly discovered zone of mineralization, now known as the Falcon 311 zone. The intervals are significant in that they are broader than what is typical for Eagle River, which bodes well for potential mineability. We are also highly encouraged by initial drilling along the eastern contact of the mine diorite that is already returning high grades from within the volcanic rocks. Both these new areas have the potential to provide additional mining horizons and optimize use of current infrastructure, ultimately providing additional reserves extending mine life and/or mill throughput.

Having discovered gold mineralization both east and west of the mine highlights the strength of the mineralized system and the potential of the surrounding volcanic rocks that have received limited exploration in recent years."

In October, the Company announced initial drill results that returned high grade gold values west of the mine diorite (See "Wesdome Drilling Returns High Grades in Volcanic Rocks Along Western Extension of Mineralization at the Eagle River Mine"). Follow up drilling has confirmed that the zone extends to the 900-metre level and remains open down plunge (Figure 1). Additionally, several of the most recent intersections are wider in width than is typical for the Eagle River mine, often greater than 5 metres true thickness (Figure 2). Furthermore, distribution of gold grades are generally more consistent across the zone than in the mine diorite. The definition and expansion of this new discovery will remain a priority for drilling in the coming months.

West side of the mine diorite, expanding the newly discovered Falcon 311 zone:

• Hole 857-E-03: 15.1 g/t Au over 8.7 m core length (15.1 g/t Au capped, 6.7 m true width)
• Hole 857-E-01: 9.5 g/t Au over 7.1 m core length (9.5 g/t Au capped, 5.8 m true width)
• Hole 857-E-09: 18.4 g/t Au over 1.6 m core length (within 18.4g/t Au capped over 0.6 m true width)
  

All assays capped at 125 g/t Au. True widths are estimated based on 3D model construction.

East of the mine diorite, near the historic 6 zone, initial drilling has identified gold mineralization in volcanics, confirming our theory that volcanic rocks along this trend are a host for gold mineralization, particularly in proximity to the diorite contact (Figure 1).

Initial drill results from the East side of the mine diorite, near the historic 6 zone:

• Hole 758-E-412: 122.5 g/t Au over 1.7 m core length (93.5 g/t Au capped, 1.5 m true width)
• Hole 580-E-93: 32.1 g/t Au over 1.7 m core length (32.1 g/t Au capped, 1.5 m true width)
• Hole 580-E-88: 29.2 g/t Au over 1.7 m core length (within 29.2 g/t Au capped over 1.6 m true width)
  

All assays capped at 125 g/t Au. True widths are estimated based on 3D model construction.

Both of these new volcanic-hosted zones have the potential to extend from surface and down plunge to depths equal to that of the neighbouring 300E Zone that has been tested to 1,500 vertical metres below surface.

Technical Disclosure

The sampling of, and assay data, from drill core is monitored through the implementation of a quality assurance - quality control (QA-QC) program designed to follow industry best practice. Underground drill samples are transported in sealed bags to the Eagle River Mine assay office in Wawa, Ontario. Samples are analyzed for gold using standard fire assay technique with gravimetric finish. Wesdome inserts blanks and certified reference standards into the sample sequence for quality control at the laboratory. The QA/QC procedure is described in more detail in the 2022 Technical Report filed on SEDAR on April 22, 2022.

The technical content of this release has been compiled, reviewed, and approved by Aliou Sene, P.Geo., Chief Mine Geologist at Eagle River Complex who is the Company's "Qualified Person" as defined in National Instrument 43-101 -Standards of Disclosure for Mineral Projects.
