Notes:
Data is reported to significant figures and differences may occur due to rounding
Mineral Resources are inclusive of Ore Reserves
Mt Carlton V2 deposit Mineral Resources have been reported above a cut-off grade of 0.35 g/t gold and A39 deposit reported above 42g/t silver Mt Carlton V2 deposit was estimated using E-Type Multiple Indicator Kriging into blocks with dimensions 25 metres east by 25 metres north by 5 metres elevation
Mt Carlton A39 deposit was estimated using a combination of Ordinary Kriging, for more broadly spaced Resource Definition drilling, and Sequential Gaussian Simulation for close spaced grade control drilled areas of the deposit into blocks with dimensions 10 metres by 10 metres by 2.5 metres elevation
Competent Person: John Winterbottom a member of Australian Institute of Geoscientists
The gold equivalence calculation represents total metal value for each metal summed and expressed in equivalent gold grade and ounces. The prices used in the calculation being A$1350/oz Au, A$28.00/oz Ag and A$2.00/lb Cu. Metallurgical recovery to concentrate of 90.0% for gold, 92.0% for silver at V2 and 88.0% silver at A39 and 92.0% for copper as indicated by metallurgical testwork
1 Troy Ounce = 31.1034768 grams
Au Eq for Silver = ((Price Ag per Oz x Ag Recovery)/(Price Au per Oz x Au Recovery)) x Ag Grade
Au Eq for Copper = ((Price Cu per lb x 2204.623) x (Cu Recovery)) / (Price Au per Oz x Au Recovery / 31.1034768) x (Cu Grade / 100)

Notes:
Data is reported to significant figures and differences may occur due to rounding V2 Ore Reserves are reported above a 0.69 g/t gold cut-off and A39 Ore Reserves reported above a 53 g/t silver cut-off
Ore Reserves were calculated using a gold price of A$1,350/oz, silver price of A$28.00/oz silver price and copper price of A$2.00/lb
V2 deposit used variable recoveries proportionate to head grade with gold recovery ranging from 82.0% to 90.0%, silver and copper recoveries ranged from 84.0% to 92.0%
A39 deposit used 88.0% and 92.0% for silver and copper recoveries respectively Smelter payabilities were also considered in the reserve calculation Competent Person: Tony Wallace a member of the Australasian Institute of Mining and Metallurgy
The gold equivalence calculation represents total metal value for each metal summed and expressed in equivalent gold grade and ounces. The prices used in the calculation being A$1350/oz Au, A$28.00/oz Ag and A$2.00/lb Cu. Metallurgical recovery to concentrate of 90.0% for gold, 92.0% for silver at V2 and 88.0% silver at A39 and 92.0% for copper as indicated by metallurgical testwork
Au Eq for Silver = ((Price Ag per Oz x Ag Recovery)/(Price Au per Oz x Au Recovery)) x Ag Grade
Au Eq for Copper = ((Price Cu per lb x 2204.623) x (Cu Recovery)) / (Price Au per Oz x Au Recovery / 31.1034768) x (Cu Grade / 100)
