TEMCO owners South32 announced in May they would be reviewing their manganese smelters in South Africa, Gauteng and TEMCO at Bell Bay.

The review is examining three possible options for the businesses which are closure, divestment or care and maintenance with an update due in October 2019.

Premier Will Hodgman said the state government was ensuring that they remain in close contact with South32 about the future of TEMCO.

"I've met with senior executives recently and of course we continue to engage with all our industrials," Mr Hodgman said.

"It's important to continue to liaise with them about their plans and as they've said they'll make those clearer towards the end of the year."

Mr Hodgman said it was too soon for assumptions to be made on TEMCO's future.

"They've [South32] made it very clear that their review process that is underway will take some months to conclude," Mr Hodgman said.

"We will not preempt any outcomes of that with our clear message to them and all our major industrials that they're an important part of Tasmania's economic landscape. We look forward to them making some clear decisions about their long term future."

TEMCO is Australia's only manganese alloy smelter and employs 300 people. Labor spokesperson Michelle O'Byrne said she was hoping to get some resolution soon about the future of TEMCO.

"I know that staff in the region who are employed by TEMCO through South 32 are genuinely concerned about their future," she said.

"The organisation has been upfront about the process its going through but as uncertainty prevails then obviously people start to make decisions about their own viability and the viability of their families.

"We certainly need it, its a viable part of the Tasmanian economy and I would hope that government's working closely with them to do whatever it can to ensure that this company remains sustainable in Tasmania."

Newly elected George Town mayor Greg Kieser said all Tasmanians would feel an impact to a degree if TEMCO decided to adjust their operations.

"Focus has to be to support Bell Bay as a region because it does have some very unique attributes I don't think you can find anywhere else in Australia," he said.

"If we play to those strengths we can still attract additional tenants that can maybe fill the gap that TEMCO leaves if they decide to close their operations, and I do stress that we still have a fair way to reach a final conclusion on that review."

The community is raising funds for four local charities as part of The Examiner's Winter Relief Appeal. Can you help?
