Within cost estimates
The company said the Gruyere project remained within forecast total cost estimates.

Gold Road discovered Gruyere in October 2013 and later partnered with Gold Fields to develop the project.

Revenues over the mine life would be $6.48 billion, with both partners taking a $3.24 billion share.
