Shree Minerals was granted approval to proceed with its iron ore mine at Nelson Bay River in Tasmania, but with 30 conditions.

Australian federal environment minister, Mark Butler, gave the go-ahead to a controversial mine that the courts halted amid concerns it could drastically affect the last stronghold of the Tasmanian devil. Among the conditions Butler called for are a ban on travel to and from the site outside daylight hours to reduce the chance of devils being run over by trucks. Shree employees will also have to get to the mine via a bus, rather than travel there in their own cars, The Guardian reported.

The Save the Tarkine campaign group, which earlier convinced the federal court to block the mine, said it would launch a further legal challenge, claiming that Butler had not taken the time to make a full assessment of the mine’s impact.

The federal court had ruled that Tony Burke, the previous environment minister, had erred by failing to properly consult departmental advice relating to the mine’s adverse implications for the Tasmanian devil.

Around 80 percent of the Tasmanian devil population has been ravaged by a facial tumor disease, with the last remaining tumor-free population found in the Tarkine, where the mine is to be located.

In order to proceed with the mine, Shree Minerals will have to monitor devil populations and contribute $350,000 to the Save the Tasmanian Devil program. The company will have to pay $48,000 for each devil killed, as well as fund the eradication of feral dogs and cats should a spotted-tailed quoll, another endangered marsupial, die.

Butler has also demanded that Shree put $400,000 towards research into four rare orchids found in the vicinity of the mine.

“I have imposed conditions that I am confident will protect those species,” Butler said. “These conditions include a range of avoidance and mitigation measures that will reduce the likely impacts. Where significant residual impacts remain likely, however, the company must take other action to compensate for the impacts, known as offsets. These conditions will ensure that there are strong environmental protections in place for a development with significant economic potential for north-west Tasmania.”

The mine has been strongly backed by the state Labor government, the Coalition and resources industry. It's estimated that the $20 million project will employ around 70 people in an area that has struggled, compared with the rest of Australia, to create jobs and stimulate economic growth.
