Notes on the 2026 Mineral Resource Estimate:
1. The MRE was completed by Kevin Hon, B.Sc., P.Geo., Senior Resource Geologist with APEX. Mr. Hon is an independent Qualified Persons, as defined by NI 43-101, and are responsible for the completion of the Mineral Resource Estimate, with an effective date of April 13, 2026. Michael Dufresne, M.Sc., P.Geo., President & CEO of APEX, completed a peer review of the estimate.
2. Mineral Resources, which are not Mineral Reserves, do not demonstrate economic viability. There has been insufficient exploration to define the Inferred Resources tabulated above as an Indicated or Measured Mineral Resource, however, it is reasonably expected that the majority of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. There is no guarantee that any part of the Mineral Resources discussed herein will be converted into a Mineral Reserve in the future. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. The Mineral Resources herein were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum standards on mineral resources and reserves, definitions, and guidelines prepared by the CIM standing committee on reserve definitions and adopted by the CIM council (CIM 2014 and 2019).
3. The Mineral Resources Estimate is underpinned by data from 546 reverse circulation and diamond drillholes totaling 20,460m of drilling that intersected the mineralized domains.
4. The mineral resource is reported at a lower cut-off of 0.3 g/t Au for the conceptual open pit and 1.5 g/t Au for the conceptual underground extraction scenario. The lower cut-off grades and potential mining scenarios were calculated using the following parameters: mining cost = US$2.75/t (open pit); G&A = US$2.00/t; processing cost = US$17.00/t; recoveries = 84%, gold price = US$3,000/oz; royalties = 1%; and minimum mining widths = 1.5 meters (underground) in order to meet the requirement that the reported Mineral Resources show “reasonable prospects for eventual economic extraction”.
5. Original Au assays were composited to 1.5 m with 13,471 composites generated overall in the mineralized domains including 11,548 composites generated for the Central Zone, 1,267 for the Mid-Realm / South Mouth Zone, and 654 for the Silica Ridge / Hamburger Hill Zone.
6. Grade interpolation was performed by ordinary kriging (OK) using 1.5 meters composites (block size of 3m x 3m x 3m).
7. A density of 2.74 g/cm3 was used for both mineralized and unmineralized zones.
8. The mineral resources estimate is categorized as indicated or inferred and classified based on data density, data quality, confidence in the geological interpretation and confidence in the robustness of the grade interpolation. The indicated category was defined by a search ellipse extending 75m along the major axis, 35m along the minor axis, and 10m vertical. In addition, a minimum of 3 drill holes were required, reporting 9 samples with a maximum of 3 samples per drill hole. The inferred category was defined using a search of up to 120 m and requiring at least 1 sample per drillhole from a minimum of 2 drillholes.
9. High-grade capping supported by statistical analysis was completed on composite data for each zone and was established at 35 g/t Au for the Central Zone, no Au capping for the Mid Realm - South Mouth Zone, and 10.2 g/t Au for the Silica Ridge – Hamburger Hill Zone.
10. The number of metric tonnes and gold ounces were rounded to the nearest thousand, and any discrepancies in the totals are due to rounding effects. Metal content is presented in troy ounces (tonnes x grade (g/t) / 31.10348).
11. The author is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues or any other relevant issue that could materially affect the mineral resource estimate.
12. The effective date of the Mineral Resources Estimate is April 13, 2026, and the effective date for the drill-hole database used to produce this Mineral Resource Estimate is February 10, 2026.
