Commenting on the award of the LOI, GR Engineering’s Managing Director, Mr Geoff Jones, said:

“GR Engineering has established a sound and successful working relationship with Gascoyne commencing in 2012. The award of the LOI will enable GR Engineering to continue assisting Gascoyne advance the highly prospective Dalgaranga Project through its final pre-development activities and into detailed design and construction. GR Engineering looks forward to Gascoyne emerging as a significant new Australian gold producer.”

Potential earnings from the Contract are not expected to alter the anticipated FY17 financial outcomes referred to in the Company’s HY17 results announcement of 27 February 2017.
