GR Engineering says it has won a $30.3 million contract with Doray Minerals for the engineering, procurement and construction of the processing plant at its Andy Well gold project near Meekatharra.
The formal appointment follows GR being named preferred contractor in July last year.
GR managing director Joe Ricciardo said work on the Andy Well gold project was already underway and was proceeding on time and on budget.
"GR Engineering was selected to design and construct the Andy Well Gold Project processing plant after working with Doray on the bankable feasibility study for the project," he said.
"This contract award is a further endorsement of GR Engineering's ability to assist clients from project inception through to project execution and delivery."
GR shares were up one cent to 85.5 cents at 10.30am while Doray shares were flat at 77 cents.
