  • The Gruyere project in Western Australia is a 50:50 joint venture between Gold Road Resources and Gruyere Mining Company Pty Ltd, a wholly owned Australian subsidiary of Gold Fields
  • The Gruyere Gold Project is making significant headway, with construction on budget and schedule, the mining contract has been awarded and the process plant construction is progressing well
  • Technical work and project preparation to optimise and deliver on the October 2016 feasibility study for Gruyere continues. This will be a low-cost operation, with average annualised production scheduled at 270koz
  • Updated resource modelling in 2017 demonstrates robust geology and Reserves from the primary production pit
  • First ore production from Gruyere is expected at the end of 2018. Project schedule remains on track to pour first gold at the end of the first quarter in 2019
  • Drilling of six new boreholes below the Resource pit shell in 2017 returned nominally lower grades. At current gold prices and technical inputs, this resulted in a small decrease of Inferred Resources
