- The effective date of the mineral reserves estimate is December 31, 2022.
- 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.
- Mineral Reserves are reported above the 3.88 g/t cut-off grade for Kiena and 6.52g/t for Eagle River.
-
Mineral Reserves demonstrated economic viability with the following parameters:
- 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.
- The minimum mining width used at Kiena was 2.1m, and Eagle River is 1.5m,
- 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,
- 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,
- A mine recovery factor of 90% is applied at Kiena and Eagle River,
- The mining cost per tonne at Kiena is C$131.4/t and C$154.6/t at Eagle River,
- The milling cost per tonne at Kiena is C$46.0/t and C$89.7/t at Eagle River,
- The surface and G&A cost per tonne at Kiena is C$45.7/t, and Eagle River is C$94.6/t,
- Selling cost of C$ 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%,
- A bulk density factor of 2.8 tonnes per cubic m (t/m³) at Kiena and 2.7 (t/m³) at Eagle River.
- The Kiena Deep Zone incorporates, A, A1, A2, H1ZA, BZA1, BZA2 and Sneak lenses.
- 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.
- Mineral Reserves have been estimated following the Standards of the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”).
- As required by reporting guidelines, rounding may result in apparent summation differences between tonnes, grade, and metal content.

- The effective date of the estimate is December 31, 2022.
- The Eagle River Mineral Resource estimate under the supervision of Company personnel was prepared by Cath Pitman P.Geo., an independent contractor. Niel de Bruin P.Geo, Director of Geology at the Company, reviewed and updated portions of the Eagle River estimate and reviewed the Mishi estimate. Karine Brousseau, P. Eng., Senior Engineer – Mineral Resources at the Company, was responsible for the Kiena estimate. All above persons are considered a ″Qualified Person″ as defined in NI 43-101.
- Mineral resources are reported exclusive of mineral reserves; mineral resources that are not mineral reserves do not have demonstrated economic viability.
- Mineral resources at Kiena and Eagle River Mine are considered for underground extraction and within potentially mineable volumes. Kiena’s mineral resource is reported below the 100m crown pillar. Must take material inside these volumes below the stated block grade cut-off has been included in the total.
- Mineral resources at Mishi are considered for open pit extraction and have been reported within a conceptual pit design.
- A bulk density factor of 2.8 tonnes per cubic m (t/m³) was applied at Kiena and 2.7 tonnes per cubic m (t/m³) at Eagle River and Mishi pit.
- Resources have been reported considering mining progress as of December 31, 2022.
- Resources are reported using a 3.2 g/t Au cut-off grade at Kiena, 5.36 g/t Au at Eagle River and 0.52g/t Au at Mishi.
-
Economic parameters for the determination of the cut-off grades include:
- A gold price of C$1,950 (US$1,500) per ounce and a USD:CAD exchange rate of 1.30,unchanged from previous year.
- Mining cost for Kiena, Eagle River, and Mishi were C$105/t, C$110/t and C$5.0/t milled, respectively,
- Kiena’s processing cost was C$46/t; Eagle River was C$89.7/t, and Mishi pit at C$21/t which included base processing, sustaining CAPEX and G&A,
- The G&A cost were C$45.7/t milled at Kiena; and C$94.6t/t milled at Eagle River, with surface costs included in the G&A costs,
- Mill recovery for Kiena, Eagle River and Mishi were respectively 98.5%, 97% and 82%,
- Selling costs of C$2.20/oz for Kiena, C$6.55/oz for Eagle River and C$6.65/oz for Mishi were used,
- Mineral resources are classified following CIM standards.
- As required by reporting guidelines, rounding may result in apparent summation differences between tonnes, grade, and metal content.
Technical Disclosure
The technical content of this release has been compiled, reviewed and approved by Jacqueline Wheeler, P. Eng, Director, Corporate Development and Technical Projects and Michael Michaud, P.Geo., Vice President, Exploration of the Company and each a "Qualified Person" as defined in National Instrument 43-101 -Standards of Disclosure for Mineral Projects.
Cautionary Note to United States Investors Concerning Estimates of Reserves and Resources
The mineral reserve and resource estimates reported in this news release were prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) as required by Canadian securities regulatory authorities. The United States Securities and Exchange Commission (the “SEC”) applies different standards in order to classify and report mineralization. This news release uses the terms “measured”, “indicated” and “inferred” mineral resources, as required by NI 43-101. Readers are advised that although such terms are recognized and required by Canadian securities regulations, the SEC does not recognize such terms. Canadian standards differ significantly from the requirements of the SEC. Readers are cautioned not to assume that any part or all of the mineral deposits in these categories constitute or will ever be converted into mineral reserves. In addition, “inferred” mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource exists, is economically or legally mineable or will ever be upgraded to a higher category of mineral resource.
