Summary of Indicated and Inferred Mineral Resource

⁽¹⁾ Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.⁽²⁾ The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.⁽³⁾ The Mineral Resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.⁽⁴⁾ The Mineral Resource Estimate was prepared for a potential open pit scenario using a constrained pit shell (with 45-degree slopes) at a 0.7 g/t gold equivalent cut-off grade and an underground mining scenario using a 0.75 g/t gold equivalent cut-off grade. Cut-off grades were derived from US$ 1,850/oz gold, US$ 21/oz silver, US$ 3.75/lb copper, CAD:USD of 0.77, C$ 2.50/tonne open pit and C$8.50 underground mining cost, C$ 48.25/tonne milled processing costs for the Copper Belle, 300H, R66, DS5 and 300N domains, and C$ 28.50/tonne milled processing costs for the CS-600 domain, and a C$ 1.50/tonne G&A cost. Process recoveries of 90% for gold, 80% for copper, and 80% for silver were used for the CS-600 domain and 90% for gold and 80% for silver with no copper for all other mineral domains⁽⁵⁾ AuEq g/t = Au g/t + (Ag g/t*0.01009) + (Cu ppm*0.0001236)⁽⁶⁾ A mineral estimate of the material within the defined pit that exists outside of the outlined mineral domains was completed and is included within the Inferred Mineral Resource.
