TriAusMin says 400 mining jobs could be on offer if its plans to recommence operations at the abandoned Woodlawn mine near Tarago in NSW are successful.
According to ABC Illawarra the company has $150 million plans to mine zinc, copper, lead, gold, and silver tailings at the mine.
It also has plans to restart underground mining at Woodlawn, with exploration drilling already in process.
The company said there was unlikely to be significant environmental impact from recommencing operations because the area was already a mine site.
TriAusMin told the ABC the mine had not been used since 1998 but it believed there were still high quality deposits on site.
So far the company has reported a resource of around one million tonnes of zinc, 0.4 million tonnes of lead, 0.18 million tonnes of copper, 27 million ounces of silver and 167,000 onces of gold.
