Mining firm Rio Tinto has announced its operations in the Highlands are under review, leaving around 150 staff concerned for their jobs.

The firm said "all options" would be considered for its aluminium smelter and hydroelectric plants in Fort William and Kinlochleven.

Lochaber MSP Dave Thompson has called for the Scottish Government to get involved to ensure a good outcome from the review. He is seeking to meet the firm's managers on Saturday to discuss the issue.

Rio Tinto said it would keep employees informed about the changes during what would be a "difficult time".

A statement from the multinational firm releasd on Friday said: "We have advised our employees in the Lochaber business that in light of the current market prospects and economic environment, and as part of our ongoing review of our businesses, Rio Tinto is launching a strategic review of its assets in Lochaber.

"This strategic review is the start of a process, during which we will be talking to our employees, key stakeholders and partners.

"The review will include the aluminium smelter, the hydro-electric power stations located in Fort William and in Kinlochleven as well as estate lands located in the Scottish Highlands. I want to emphasise that all options will be considered."

It added: "Given the broad diversity of assets at Lochaber, the review will consider various scenarios to ensure that all options are fully assessed, in keeping with Rio Tinto’s standard practice in conducting such reviews.

"We recognise that this is a difficult time for our employees and we will keep our staff informed as we move forward.

"In the meantime, it is paramount that we remain focused on keeping our employees safe and that we keep delivering the same quality product."

Mr Thompson said employees would be worried for their jobs following the news.

He said: "It is very concerning that this news has come now. I feel for the employees who must now be very concerned for their jobs.

"Only yesterday, Marine Harvest announced a restructuring and job cuts. So it is only appropriate that the Scottish Government get involved to do its best to ensure a good outcome from this review."
