1. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
2. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
3. 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 potentially be upgraded to an Indicated Mineral Resource with continued exploration.
4. The Mineral Resources were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.
5. Historical mined areas were removed from the block modelled resources.
6. Metal prices used were US$1,750/oz Au and US$20/oz Ag and 0.78 US$ CDN$ FX with process recoveries of 90% Au and 83% Ag. A C$14.50/t process cost and C$5/t G&A cost were used. The Au:Ag ratio was 80:1 for the purposes of calculating AuEq.
7. The constraining pit optimization parameters were C$3.15/t mineralized and waste material mining cost and 50° overall pit slopes with a 0.40 g/t AuEq cut-off.
8. The Out-of-Pit Mineral Resource blocks were quantified as those blocks above the 1.5 g/t AuEq cut-off, below or outside the constraining pit shell and within the constraining mineralization wireframes. Out-of-Pit Mineral Resources selected exhibited continuity and reasonable potential for extraction by the long hole underground mining method. Differences may occur in totals dues to rounding.
