Wesdome Announces Annual Mineral Resource and Reserve Updates for Eagle River and Kiena Mine Complexes

TORONTO, March 13, 2023 (GLOBE NEWSWIRE) — Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome” or the “Company”) today announces updated Mineral Resource and Mineral Reserve updates at the Company’s 100% owned Kiena Mine Complex (“Kiena”) in Val d’Or, Quebec and at the Eagle River Mine (“Eagle River”) near Wawa, Ontario.

  • High Grade Mineral Reserve Base – At December 31, 2022, Wesdome’s combined proven and probable mineral reserves totalled 1.0 million ounces (2.4 million tonnes grading 12.9 grams per tonne (“g/t”) gold); combined measured and indicated mineral resources (exclusive of reserves) were 350 thousand ounces (1.4 million tonnes grading 7.7 g/t gold); and combined inferred mineral resources were 1.1 million ounces (6.4 million tonnes grading 5.2 g/t gold). Reserves and Resource estimates at both sites reflect higher cut-off grades, reduced exploration budget in H2, a higher allocation towards definition and infill drilling (including 25,000 metres in the Falcon Zone at Eagle River), as well as a more stringent and robust approach to reconciliation, 3D modeling and resource classification.
  • Upgrading Near-mine Discoveries A Focus – In 2023, the Company has budgeted 137,000 metres of drilling, with a primary focus on the expansion of mineral reserves and mineral resources and delineating the new discoveries made in 2022. At Kiena, the Company is following up on multiple initial discoveries made last year, including the south limb of the A Zone and several adjacent hanging wall zones which remain outside of mineral reserves. An exploration ramp is specifically budgeted to follow-up and expand on the near-surface Presqu’ile Zone. To the west of Eagle River the Company believes there is potential for the delineation of a parallel Falcon structure and further to the East down dip extension of the high grade 300 Zone that could meaningfully enhance future operational flexibility of the asset. With an existing large resource base, efforts in 2023 will focus on converting a portion of these resources to reserves. Additionally, we have a number of recently discovered zones and exploration targets at both projects.
  • Kiena Ramp Development Tracking Well – Since year-end, ramp development has continued to track slightly ahead of budget, with completion of the ramp to the 129 m-level scheduled by year end. Completion of this ramp segment will provide access to the high grade Kiena Deep A Zone, which is associated with areas with the highest ounces per vertical metre located within the zone.

Notes:

  1. The effective date of the mineral reserves estimate is December 31, 2022.
  2. The Mineral Reserves estimate for Kiena was prepared by Simon Fontaine P. Eng, Senior Mining Engineer, an employee of the Company. Benoit Beaulieu P.Eng, an independent consultant under the supervision of Company personnel, prepared the Eagle River estimate. 
  3. Mineral Reserves are reported above the 3.88 g/t cut-off grade for Kiena and 6.52g/t for Eagle River. 
  4. Mineral Reserves demonstrated economic viability with the following parameters:
    1. A gold price of C$1,820 (US$1,400) per ounce for the Reserves, with a USD:CAD exchange rate of 1.30, unchanged from previous year.
    2. The minimum mining width used at Kiena was 2.1m, and Eagle River is 1.5m,
    3. External dilution for S50 & Martin zones, Sneak, H1ZA, BZA1 and BZA2 lenses in the Kiena Deep zone was calculated at 15%. Variable external dilution parameters for ZA, A1 & A2 lenses in the Kiena Deep zone varied from 0.1m to 1.25m depending on the zone. At Eagle River, an additional 0.5m is external to the footwall and hanging wall stopes, except for the 300 zone below 1090m, where a value of 1.25m is applied to the footwall and hanging wall, 
    4. A dilution grade of 0.7 g/t Au is applied for the S50 Zone; for all other zones at Kiena, a dilution grade of zero is used. At Eagle River, waste blocks were estimated using a 3.0 g/t gold cut-off, with un-estimated blocks assigned a 0.16 g/t gold value,
    5. A mine recovery factor of 90% is applied at Kiena and Eagle River,
    6. The mining cost per tonne at Kiena is C$131.4/t and C$154.6/t at Eagle River,
    7. The milling cost per tonne at Kiena is C$46.0/t and C$89.7/t at Eagle River,
    8. The surface and G&A cost per tonne at Kiena is C$45.7/t, and Eagle River is C$94.6/t,
    9. Selling cost of C$ 2.20/oz, and 97% metallurgical processing recovery for the S50 & Martin Zones and 98.5% for the Kiena Deep Zone. Eagle’s selling cost is C$6.55/oz, and the percentage mill recovery is 97.0%,
    10. A bulk density factor of 2.8 tonnes per cubic m (t/m³) at Kiena and 2.7 (t/m³) at Eagle River.
  5. The Kiena Deep Zone incorporates, A, A1, A2, H1ZA, BZA1, BZA2 and Sneak lenses.
  6. Stopes with more than 50% of Measured Resources were classified as Proven Reserves at Kiena. Proven and Probable reserves are based on the block model classification at Eagle River.
  7. Mineral Reserves have been estimated following the Standards of the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”).
  8. As required by reporting guidelines, rounding may result in apparent summation differences between tonnes, grade, and metal content.
