Notes for Ore Reserve Statement December 2023

  • OP = Open Pit
  • All Ore Reserves are completed in accordance with the 2012 JORC Code Edition
  • All figures are rounded to reflect appropriate levels of confidence. Apparent differences may occur due to rounding.
  • The Gruyere JV is a 50:50 joint venture between Gold Road and Gruyere Mining Company Pty Limited, a wholly owned Australian subsidiary of Gold Fields Ltd. Figures are reported on a 100% basis unless otherwise specified, 50% is attributable to Gold Road
  • Gold Road holds an uncapped 1.5% net smelter return royalty on Gold Fields’ share of production from the Gruyere JV once total gold production exceeds 2 million ounces
  • The pit design for reporting the Gruyere Ore Reserve is derived from mining, processing and geotechnical parameters as defined by operational studies, FS and PFS level studies completed between 2019 and 2023 and the 2016 FS. The Ore Reserve is reported using the 2023 Mineral Resource model constrained within the pit design (which is derived from a A$1,575 per ounce optimisation) and with Ore Reserves reported at A$2,000 per ounce gold price
  • The Ore Reserve for the Golden Highway Deposits which include Attila, Argos, Montagne and Alaric is constrained within a A$2,000 per ounce mine design derived from mining, processing and geotechnical parameters as defined by the 2020 PFS and operational studies
  • The Ore Reserve is evaluated using variable cut-off grades (fresh, transitional and oxide respectively): Gruyere – 0.57, 0.54, 0.54 g/t Au. Attila – 0.69, 0.62, 0.58 g/t Au. Argos – 0.64, 0.64, 0.62 g/t Au. Montagne – 0.67, 0.60, 0.59 g/t Au. Alaric – 0.68, 0.68, 0.66 g/t Au
  • Ore block tonnage dilution and mining recovery estimates: Gruyere – 6% and 99%. Attila – 21% and 99%. Argos – 17% and 89%. Montagne – 15% and 94%. Alaric – 31% and 99%
  • Gruyere Proved category includes Surface Stockpiles. Ore Reserves are depleted for mining

Notes for Mineral Resources Statements December 2023

  • OP = Open Pit and UG = Underground
  • All Mineral Resources are completed in accordance with the JORC Code 2012 Edition
  • All figures are rounded to reflect appropriate levels of confidence. Apparent differences may occur due to rounding
  • Mineral Resources are inclusive of Ore Reserves. Gruyere Measured category includes Surface Stockpiles (5.55 Mt at 0.71 g/t Au for 0.13 Moz). Mineral Resources are depleted for mining
  • The Gruyere JV is a 50:50 joint venture between Gold Road and Gruyere Mining Company Pty Ltd, a wholly owned Australian subsidiary of Gold Fields Ltd. Figures are reported on a 100% basis unless otherwise specified, 50% is attributable to Gold Road. Gold Road’s 50% attributable Mineral Resource for Gruyere Underground is reported independently of the Gruyere JV
  • The Gruyere and Golden Highway Open Pit Mineral Resources are reported between 0.47 to 0.58 (oxide) and 0.50 to 0.61 (fresh) g/t Au cut-off grade. The Orleans and YAM14 Open Pit Mineral Resources are reported at 0.4 g/t Au cut-off grade. The Renegade, Gilmour, Smokebush and Warbler Mineral Resource are reported at 0.5 g/t Au cut-off grade. Cut-off grades allow for processing costs, recovery and haulage to the Gruyere Mill
  • The Gruyere Open Pit Mineral Resource is constrained within a A$2,300 per ounce optimised pit shell. The Golden Highway, Orleans and YAM14 Open Pit Mineral Resources are constrained within A$2,000 per ounce optimised pit shells. The Renegade, Gilmour, Smokebush and Warbler Open Pit Mineral Resources are constrained within A$2,200 per ounce optimised pit shells. Gold prices are derived from mining, processing and geotechnical parameters from the Golden Highway PFS, the Gruyere FS and current Gruyere JV operational cost data
  • The Underground Mineral Resource at Gruyere was evaluated by Gold Road on the same geology model used to estimate the December 2023 Open Pit Mineral Resource. The model was evaluated exclusively below the A$2,300 per ounce pit optimisation shell utilised to constrain the Open Pit Mineral Resource and is reported as 100% in the Inferred category
  • The Underground Mineral Resource at Gruyere is constrained by Mineable Shape Optimiser (MSO) shapes of dimensions consistent with underground mass mining. The MSO shapes are optimised at cut-off grades based on benchmarked mining costs, current Gruyere operating costs and processing recoveries at a A$2,000 per ounce gold price
  • Underground Mineral Resources at Gruyere considered appropriate for potential mass mining exploitation in the Central Zone are constrained within MSO shapes of 25 metre minimum mining width in a transverse orientation and 25 metre sub-level interval, and are optimised to a cut-off grade of 1.0 g/t Au
  • Underground Mineral Resources at Gruyere considered appropriate for potential mass mining exploitation in the Northern Zone are constrained within MSO shapes of 5 metre minimum mining width in longitudinal orientation and 25 metre sub-level interval and are optimised to a cut-off grade of 1.5 g/t Au
  • Underground Mineral Resources at Central Bore are constrained by a 1.5 metre minimum stope width that are optimised to a 3.5 g/t Au cut-off reflective of a A$1,850 per ounce gold price
  • Underground Mineral Resources at Gilmour are constrained by an area defined by a 2 metre minimum stope width and a 3.0 g/t Au cut-off reflective of a A$2,200 per ounce gold price
  • Underground Mineral Resources are reported with diluted tonnages and grades based on minimum stope widths
