Notes:

A GMV $/t cut-off of $20/t was used, and the GMV formula is: GMV $/t = Au(grams)*74.5%*$56.26+ Cu(tonnes)*85%*$7.714 + 

Ag(grams)*50%*$0.71

• Base metal prices considered were $3.50/lb copper, $22.00/oz silver, and $1,750/oz gold. 

• The Mineral Resource is stated within a pit shell using the base-case metal prices.

• Mineral Resources are estimated and reported in accordance with the CIM Definition Standards for Mineral Resources and Mineral 

Reserves adopted 10 May 2014.

• Matthew Dumala (P.Eng.), is the independent Qualified Person with respect to the Mineral Resource estimate.

• The Mineral Resource is not believed to be materially affected by any known environmental, permitting, legal, title, taxation, socioeconomic, marketing, political or other relevant factors.

• These Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. 

• The quantity and grade of reported Inferred Resources in this Mineral Resource estimate are uncertain in nature and there has been 

insufficient exploration to define these Inferred Resources as Indicated or Measured; however, it is reasonably expected that the 

majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

• Effective date of the report was December 27, 2021.
