* Au and Ag Indicated resource contained within 64.3 million tonnes; Au and Ag Inferred resource contained within 125.9Mt. The current Mineral Resource Estimate and PEA include only open-pit mineralization. All underground mineralization has been excluded from the resource model and mine plan. For more information on the Mineral Resource Estimate, see the Preliminary Economic Assessment NI 43-101 Technical Report; Effective January 26, 2026.

** The PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.

Summary Of project Economics

Mineral resources that are not mineral reserves have no demonstrated economic viability. No mineral reserves have been calculated for the Project. There is no guarantee that any part of the mineral resources discussed herein will be converted to a mineral reserve in the future

** The PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.

Note: all information presented in Canadian dollars unless otherwise stated.

Base Case: Gold US$2,750/oz, Silver US$35.00/oz
CAD/USD $1.34.

Consensus Case: Gold US$3,300/oz, Silver US$40.00/oz CAD/USD $1.35 Source: CIBC Capital Markets.

Upside Case: Gold US$5,000/oz, Silver US$80.00/oz CAD/USD $1.35.

Cash operating costs consist of: mining costs, processing costs and site G&A.

AISC: consist of cash operating costs, royalties, corporate G&A, selling costs and silver credits and excluding pre-production capital costs. Refer to the disclosure under the “Non-GAAP Financial Measures” heading of page 3 of this Presentation for more information.

Base Case illustrates Large-scale gold production

1 Gold equivalency based on payable Gold and Silver and calculated using US$2,750/oz Au, US$35.00/oz Ag. The PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.

Notes to the Mineral Resource statement:

1. The mineral resources described above have been prepared in accordance with the CIM Standards (Canadian Institute of Mining, Metallurgy and Petroleum, 2014) and follow Best Practices outlined by the CIM (2019).

2. The Qualified Person, as defined by NI 43-101, (“QP”) for this MRE for both the Moss Deposit and the East Coldstream Deposit is Mr. Dominic Lussier, P.Geo., of G Mining Services Inc., who is responsible for the MRE. The effective date of the MRE is January 16, 2026, and is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing, political, or other relevant factors that could materially affect the Mineral Resource estimate

3. Mineral resources that are not mineral reserves have no demonstrated economic viability. No mineral reserves have been calculated for the Project. There is no guarantee that any part of the mineral resources discussed herein will be converted to a mineral reserve in the future.

4. The quantity and grade of reported Inferred Mineral Resources are uncertain, and there has not been sufficient work to define these Mineral Resources as Indicated or Measured. Further work may result in the upgrading of portions of the Inferred Mineral Resources. There is no certainty that Inferred Mineral Resources will be converted to Measured or Indicated Mineral Resources.

5. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, market, or other relevant factors.

6. Known underground works at the Moss Deposit have been incorporated into the block model, and zero density has been assigned to the blocks located within the voids.

7. Tonnage estimates are based on individually measured and calculated bulk densities for geological units ranging from 2.69 to 2.725 g/cm³. Overburden density is set at 1.8 g/cm³.

8. A total of 122 mineralized zones for the Moss Deposit (used for both Au and Ag estimation) and 12 mineralized zones for the East Coldstream Deposit were modeled using Leapfrog geo. High-grade capping for gold estimation of between 15.0 and 55.0 g/t (Moss Deposit) and 12 g/t (East Coldstream Deposit) was applied before compositing. High grade capping for Ag estimation of 30.0 g/t (Moss Deposit) was applied before compositing.

9. The MRE was completed using Leapfrog Edge with parent block size of 5 m x 5 m x 5 and a 1.25 m x 1.25 m x 1.25 m minimum sub block size for both the Moss Deposit and the East Coldstream Deposit. Interpolation method used for the Moss Deposit are Ordinary Kriging for the principal shears modeled and ID2 for the secondary shears. East Coldstream Deposit was interpolated using only Ordinary Kriging. Both estimations are using hard boundary between modeled domains.

10. Open pit Mineral Resources are reported within an optimized Geovia Whittle pit shell generated at a surface cut-off of 0.35 g/t Au using a gold price of US$2,200/oz; a USD/CAD exchange rate of 1.33, a mining cost of 3.67/t and a G&A cost from $2.21/t, processing cost of $12.04/t, pit slope angles of 50° for bedrock and 27° for unconsolidated material. Mineral Resources are reported at a cut-off grade of 0.35 g/t Au within this pit shell and are reported as undiluted and in situ.

11. Tonnage has been expressed in the metric system, and gold metal content has been expressed in troy ounces.

12. The tonnages have been rounded to the nearest 1,000 tonne, and the metal content has been rounded to the nearest 1,000 ounce. Totals may not sum due to rounding.
