Facilities for making alloy wheels have been proposed for the UK's last remaining aluminium smelter yard.
Liberty British Aluminium, which took over the running of the Lochaber Smelter near Fort William last year, also plans to construct a rolling mill.
The company has informed Highland Council of its plan to submit a planning application for the new facilities at a later date.
About 170 people are employed at the site.
In December, plans were announced to create up to 600 jobs and invest £120m in the yard.
Liberty British Aluminium took over the smelter from Rio Tinto in a £330m deal.
