NOTES:
1 The Mineral Reserve Estimate has an effective date of December 31 2019.
2 The CIM Definition Standards were followed for Mineral Reserves.
3 Mineral Reserves for open pit are estimated at a cut off grade of 0.40 g/t Au.
4 Mineral Reserves for underground are estimated at a cut off grade of 2.00 to 3.00 g/t Au.
5 Mineral Reserve economics are estimated using an average long term gold price of US$1,348 per ounce.
6 Dilution of 15% was factored into the estimation of underground Mineral Reserves.
7 All figures are rounded and use significant figures Subtotals, totals and weighted averages are calculated from quantities before rounding and significant figures.

NOTES:
1 Mineral Resources are quoted inclusive and not additional to those Mineral Resources converted to Mineral Reserves.
2 The reporting standard adopted for the reporting of the Mineral Resource estimate uses the terminology, definitions and guidelines given in the CIM Standards on Mineral Resources and Mineral Reserves as required by NI 43-101.
3 Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate and have been used to derive subtotals, totals and weighted averages.
4 Mineral Resources are estimated at a cut-off grade of 1.50 g/t Au for the Plutonic underground gold mine.
5 Plutonic Underground Resources based on Deswik Mining Stope Optimizations using generalized Reserve MSO input parameters and/ or restricted 'grade shell' reported Resources. Plutonic Main Pit Resources based on pit optimization parameters derived by the PEA.
6 Plutonic Open Pit Mineral Resources are estimated at a cut-off grade of 0.40 g/t Au.
7 Mineral Resources are estimated using an average gold price of AUD$2,150 per troy ounce (~US$1,505 per ounce).
8 Rounding errors exist in this table and numbers may not add correctly.
