Ormonde Mining said all elements of the crushing plant at its tungsten project in Barruecopardo in Spain will be in place by the end of September.
It said the process element of the firm’s flagship plant is now 70 per cent complete and will begin commissioning at the start of December.
Projected construction costs also remain within the projected budget of €53.6 million, it added.
Michael Donoghue, Ormonde’s chairman and interim managing director, said: “It is very pleasing to have achieved another major project milestone during the quarter, with the on-target commencement of commissioning of the crush and screen plant and the water treatment plant, taking the project into its mine commissioning phase.
“This major advancement accompanied progress on the construction of the process plant, where most of the major equipment has been installed and structural works are well advanced,” he said.
“The commissioning of the process plant is now due to commence in early December, slightly later than originally planned, with first tungsten expected to be produced from early February 2019, to commence a new secure supply to the global markets,” Mr Donoghue said.
