Wesdome Announces Initial Development on the Kiena Deep A Zone That Confirms High Grade Gold Mineralization and Recomissions Mill

TORONTO, Nov. 24, 2020 - Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome” or the “Company”) today announces initial results from underground development on the A Zone at the Company’s 100% owned Kiena Mine Complex in Val d'Or, Quebec.

Kiena Deep A Zone Development

In addition to the ongoing definition drilling, sill development is currently being completed on the Kiena Deep A Zone on 111 Level. The development will provide an opportunity to confirm the geologic interpretation of the deposit, test for spatial and grade continuity of the mineralized structures, validate key assumptions of the mineral resource estimate, and assess the rock quality characteristics. This information will assist the ongoing Prefeasibility Study (“PFS”), expected to be completed by H1 2021, which will determine timing and details of the restart of the mine.

To date, approximately 123 metres (“m”) of 3.7 m x 4.0 m lateral development have been completed on the A and A1 zones. The initial development has confirmed the continuity of the A Zone high grade gold mineralization along strike. Visible gold is associated with folded quartz veins which are located within an overall zone of strong amphibole alteration. The amphibolite is located at the contact between basalt/feldspar porphyry dyke and ultramafic rocks (Figure 1). To date, approximately 6,000 tonnes (corresponding to the 123 m of development) grading 22.1 grams per tonne gold (“g/t Au”) have been mined based on uncapped muck samples (Figure 2). The muck samples compare well with chip samples collected along the face (Figure 3). The uncapped muck samples also compare well with the gold grade estimated by the uncapped version of the block model. These results are preliminary and final results will be presented on completion of the milling. The upcoming milling of the A Zone development material will be used to reconcile the gold content estimated by the muck and chip sampling and the block model.

Highlights of the recent A and A1 Zone development include;

• Chip sample R111-ZA22W-F: 246.2 g/t Au over 3.8 m chip length (66.5 g/t Au capped) A Zone
• Chip sample R111-ZA25W-F: 785.0 g/t Au over 2.8 m chip length (71.8 g/t Au capped) A Zone
• Chip sample R111-ZA1-5W-F: 19.4 g/t Au over 4.0 m chip length (19.4 g/t Au capped) A1 Zone
• Chip sample R111-ZA1-4W-F: 156.5 g/t Au over 1.0 m chip length (100.0 g/t Au capped) A1 Zone

All assays capped to 100.0 g/t Au.

The Kiena mill has now been restarted and is currently processing waste rock and low grade mineralization in preparation to process the Kiena Deep A Zone development material later next month. The development material will come from two zones, namely the A and A1 Zones. At this time we expect to process the estimated 6,000 tonnes of the combined zones. The milling results will be used to reconcile gold production with development muck and chip samples, as well as reconcile the production with grade estimated by three-dimensional block modelling and the forecast ounces of gold, thus validating key parameters of the resource estimate. The resource estimate is currently being updated and is planned to be released this December. This resource estimate will be the base of the ongoing PFS, expected to be completed on schedule in H1 2021.

Mr. Duncan Middlemiss, President and CEO, commented, “We are very pleased with the initial development, which has thus far confirmed the high grade nature and continuity of the A Zone. Everything learned from this development will be used in support of the prefeasibility study currently underway.

“We are also very encouraged with the recommissioning of the Kiena mill, that is now processing waste rock and low grade material in advance of the A Zone development material. It confirms the readiness of the mill for future production. Initial results from the uncapped muck and chip samples indicate the grades compare with the uncapped grades in the block model, which are higher than the reported capped mineral resource and which could be very positive. This is to be confirmed with the processing of the A Zone development material within the next month.

“In addition, we remain focused on continued drilling underground with 7 drills in the Kiena Deep and VC zones. This drilling has continued to confirm the overall continuity of the geometry and the high-grade gold mineralization of the A Zone that now extends down plunge in excess of 880 m. We have also commenced our surface exploration program with 2 drill rigs to test targets adjacent to the Kiena Mine Complex. In 2021, we expect to continue our aggressive exploration program both underground and on surface to test the numerous targets that remain underexplored, and also, to progress the A Zone development ramp for drilling and future production.”

TECHNICAL DISCLOSURE

The technical and geoscientific content of this release has been compiled, reviewed and approved by Bruno Turcotte, P.Geo., (OGQ #453) Senior Project Geologist of the Company and a "Qualified Person" 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 done at ALS Minerals in Val d'Or (Quebec). Assaying was done by fire assay methods with an atomic absorption finish. Any sample assaying >100 g/t Au was rerun by 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 to monitor quality control for chip and muck samples.

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 offices. 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 our best efforts. Future conditions may warrant reduced or suspended production activities which could 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. We are continuing to closely monitor the situation and will provide updates as they become available.
