Measured and Indicated mineral resources are inclusive of mineral reserves.
Mineral resources are not mineral reserves and have no demonstrated economic viability.
The mineral resource estimate was prepared by Benjamin Parsons, MSc, of SRK, who is a Qualified Person as defined by National Instrument 43-101. Mr. Parsons has reviewed and verified
the drilling, sampling, assaying, and QAQC protocols and results, and is of the opinion that the sample recovery, preparation, analyses, and security protocols used for the mineral resource
estimate are reliable for that purpose.

Totals may not add up due to rounding.

6.
Mineral resources are reported above a cut-off grade of 1.9 g/t Au for the Upper Mine, and 1.4 g/t Au for the Lower Mine. The cut-off grades are based on a metal price of USD$1,600 per
ounce of gold, metallurgical recoveries of 85% for the Upper Mine and 95% for the Lower Mine, without consideration of revenue from other metals.
The Upper Mine is defined as the current operating mine levels above the 1,000 m elevation using cut and fill mining, and the Lower Mine is defined as below the 1,000 m elevation using
mostly long hole open stoping methods.
Mineral resources from the Transition Mine, as described in the PFS, are now included in the Upper Mine mineral resources.

8.
There are no known legal, political, environmental, or other risks that could materially affect the potential development of the mineral resources.
