A Western Australian mining company expects to gain approval for an open cut mine in Tasmania's north-west by next week.
Bass Metals is excavating 2,000 tonnes of zinc, lead and silver from Que River to test its quality.
Managing director Mike Rosenstreich says a full mining operation could have a five-year life-span and employ about 25 people.
He says the Environment Department is considering final approval of the project next week and no objections have been lodged so far.
"We don't expect any surprises at this stage, we've had good relations or contact with the people involved in that and shortly thereafter we anticipate the final approval from the Waratah-Wynyard Council," he said.
"They've certainly been very supportive to date, they've been at the site and we don't anticipate any problems with that."
