Wesdome Drilling Confirms Continuity of Presqu’île Zone and Is Investigating Installation of Exploration Ramp From Surface Adjacent to the Kiena Mine

Rhea-AI Summary

Wesdome Gold Mines Ltd. announced promising surface exploration results from the Presqu’île Zone at the Kiena Mine Complex in Quebec. The drilling confirmed the continuity of mineralized zones, with highlights including a remarkable 45.0 g/t over 3.8 m in the PR-2A Zone. The company plans to fast-track the construction of an exploration ramp to enhance resource access, operational efficiency, and potential gold production. The ongoing exploration demonstrates the property’s prospectivity, while the construction of a paste backfill plant is on track for completion by November 2022.

Positive

• Confirmed continuity of mineralized zones with significant gold grades, including 45.0 g/t over 3.8 m in recent drilling.
• Plans to fast-track an exploration ramp, improving access and operational efficiency at Kiena mine.
• Ongoing drilling in multiple zones increases potential gold feed for the Kiena mill.

Negative

• COVID-19 impacts with potential delays in production timelines and objectives due to employee infections.

TORONTO, Sept. 08, 2022 (GLOBE NEWSWIRE) -- Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome” or the “Company”) today announces surface exploration drilling results from the Presqu’île Zone at the Company’s 100% owned Kiena Mine Complex in Val d'Or, Quebec.

Since the completion of the PFS for the Kiena Mine in 2021, both surface and underground drilling has been more focused on exploration targets proximal to the Kiena Mine. Initially this drilling has been completed along strike from the Kiena Mine within the prospective Jacola Formation in order to provide additional feed for the Kiena mill. Most recently surface drilling has focused on the Presqu’île Zone located 2 kilometres west of the Kiena Mine (Figure 1). Previous drilling at the Presqu’île zones has defined a near surface mineral resource (Inferred Mineral Resource of 353,000 tonnes grading 7.1 g/t au totalling 80,600 oz of gold from 3 lenses [PR-1, PR-2, and PR-2A zones], December 31, 2021 Mineral Resources).

Recent drilling has confirmed several narrow, subparallel zones that are steeply east-plunging located proximal to a sheared mafic-ultramafic contact. The zones are generally hosted by a porphyritic basalt. The mineralization corresponds to several quartz-carbonate-chlorite veins (<40cm) mineralized with pyrite, chalcopyrite, sphalerite, galena and ±visible native gold. Quartz veins are associated with a typical biotite alteration. The drilling has confirmed the continuity of the mineralized zones. The PR-2A Zone is interpreted to be open along strike eastward and down dip and represents an excellent target for the exploration drilling at depth.

Highlights of the recent drilling are listed below and are summarized in Table 1.

• Hole PR-22-034: 24.3 g/t over 3.3 m core length (10.6 g/t Au capped*, 3.0 true width) PR-1 Zone
• Hole PR-22-026: 30.0 g/t Au over 9.4 m core length (13.1 g/t Au capped*, 9.2 m true width) PR-2A Zone
• Hole PR-22-024: 45.0 g/t Au over 3.8 m core length (18.5 g/t Au capped*, 3.7 m true width) PR-2A Zone
• Hole PR-22-029: 27.6 g/t over 3.5 m core length (12.8 g/t Au capped*, 3.3 m true width) PR-2 Zone

* All assays capped at 35 g/t. Au. True widths are estimated based on 3D model construction.

Given the significant upside that the Presqu’île zone could represent for Kiena, the Company is currently evaluating options to fast-track an exploration ramp from surface. This infrastructure would provide the ideal platform for exploration activities to test the potential of the Presqu’île area. It could also easily be connected to Kiena’s existing underground ramp network, providing access to surface for the existing operation. This could represent a significant milestone on the Company’s journey to unlock the full potential of Kiena, as it would provide a second access for conveyance of material and personnel, freeing time for additional ore hoisting via the shaft. Other gains, such as reduced ventilation costs and savings from added operational flexibility are also expected.

Mr. Duncan Middlemiss, President and CEO commented, “We are pleased with the recent surface exploration results at Presqu’île which could potentially increase our resource base in areas proximal to the mine. The Presqu’île Zone represents an opportunity to establish an exploration ramp for further exploration of the zone but also to provide access to the underground workings via a ramp system that would greatly improve efficiencies at the Kiena mine.

We are currently drilling with two drills on barges and one surface drill to explore adjacent mineralization to the Kiena mine within the Jacola Formation. Several of these areas include the Dubuisson, Shawkey, Thompson, and recently discovered Bourgo zone again having the potential to add to feed for the Kiena mill. Drilling is ongoing and updates will be released within the next several months. It is evident that as we continue to explore and collect new geological information, we are able to discover traps for gold mineralization, thereby demonstrating the prospectivity of the property.

We are also pleased with the progress being made at the construction of the paste back fill plant that is expected to be completed in November. As part of this, the most critical components of the paste fill plant, the motor control system (MCC) have been received and being installed. Commissioning remains on track for Q4 2022.”

TECHNICAL DISCLOSURE

The technical and geoscientific content of this release has been compiled and reviewed by Denys Vermette, P. Geo., (OGQ #564) Consultant Geologist for IOS Services Géoscientifiques from Chicoutimi, Qc), and approved by Bruno Turcotte, P.Geo., (OGQ #453) Chief Geologist – Underground Exploration of the Company, both "Qualified Persons" as defined in National Instrument 43-101 -Standards of Disclosure for Mineral Projects.

Analytical work was performed by ALS Minerals of Val-d’Or (Quebec), a certified commercial laboratory (Accredited Lab #689). Sample preparation was completed at ALS Minerals in Lachine (Quebec). Assaying comprised fire assay methods with an atomic absorption finish. Any sample assaying >3 g/t Au was rerun by fire assay method with gravimetric finish, and any sample assaying >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 twenty to monitor quality control.

COVID-19

The health and safety of our employees, contractors, vendors, and consultants is the Company’s top priority. In response to the COVID-19 outbreak, Wesdome has adopted all public health guidelines regarding safety measures and protocols at all of its mine operations and corporate office. These protocols are still in place at all sites despite the loosening of some provincial public health guidelines. In addition, our internal COVID-19 Taskforce continues to monitor developments and implement policies and programs intended to protect those who are engaged in business with the Company.

Through care and planning, to date the Company has successfully maintained operations; however, there can be no assurance that this will continue despite the Company’s best efforts, with the emergence of new, highly contagious variants such as Omicron. To date, the Company has been impacted by this most recent variant outbreak, with employees at both operations and corporate office becoming infected, which may negatively impact our ability to maintain projected timelines and objectives. Consequently, the Company’s actual future production and production guidance is subject to higher levels of risk than usual. The Company is continuing to monitor the situation closely and will provide updates as they become available.
