Prime Minister Malcolm Turnbull has used a visit to the Tasmanian seat of Braddon to announce the reopening of a nickel mine that’s expected to create more than 200 jobs.

Mr Turnbull was in Zeehan on Monday alongside Premier Will Hodgman on day two of a trip to the state’s west ahead of a by-election on July 28.

Mr Turnbull hailed Tasmania as a “great mining state”, adding the Apple Isle’s exports had grown by 26 per cent over the past year, lead by mineral exports.

Production at the Avebury mine, owned by Dundas Mining, is expected to restart in January after it was stopped in 2009.

The state government has given the mine $3.5 million in payroll tax relief.

“Our mining sector generates over half of Tasmania’s export value. It is so important not just to this region but also to our state,” Mr Hodgman told reporters.

“This facility has for too long sat idle and will now have life injected back into it.”

Recruitment for mining, processing and administrations jobs will begin immediately, Mr Hodgman said.
