1. The stated Mineral Reserves have been prepared in accordance with the requirements of National Instrument (“NI”) 43-101 and are classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum’s “CIM Definition Standards – For Mineral Resources and Mineral Reserves”. Mineral Reserve estimates reflect the Company’s reasonable expectation that all necessary permits and approvals will be obtained and maintained. Mining dilution and mining recovery vary by deposit and have been applied in estimating the Mineral Reserves.

2. Mineral Reserves are the economic portion of the Measured and Indicated Mineral Resources. Mineral Reserve estimates include mining dilution at grades assumed to be zero. The slope angles of all pit designs are based on geotechnical criteria as established by external consultants. The shape and size of the pit designs are guided by consideration of the results from a pit optimization program.

3. The Mineral Reserves were estimated using a gold price assumption of $1,300 per ounce.

4. The slope angles of all pit designs are based on geotechnical criteria as established by external consultants. The size and shape of the pit designs are guided by consideration of the results from a pit optimization program

5. Cut-off grades have been estimated based on operating cost projections, mining dilution and recovery, government royalty payment requirements and applicable metallurgical recovery.

6. Numbers may not add due to rounding

1. All figures are rounded to reflect the relative accuracy of the estimate and have been used to derive sub-totals, totals and weighted averages. Such calculations inherently involve a degree of rounding and consequently introduce a margin of error..

2. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

3. Mineral Resources are reported inclusive of those converted to Mineral Reserves.

4. Numbers may not add correctly due to rounding.
