Gold Road Resources Limited (Gold Road) and Gruyere Mining Company Pty Ltd, a member of the Gold Fields Limited Group (Gold Fields), are pleased to report the commissioning of the final components of the process plant is now complete at the Gruyere Gold Project (Gruyere). In particular, the ball mill and gravity circuit are now operational.

Production Guidance for 2019 remains at 75,000 to 100,000 ounces (100% basis)3, with cost guidance to be reviewed when Commercial Production is declared. Commercial Production is anticipated mid‐way through the six to seven month ramp‐up period as previously guided.

All components of the process circuit are now substantially complete and operational.
