In 2018, the Government announced lithium potential there.
If Mineralogy's bid is successful, it will have pegged out almost the entire edge of Lake Brunner, as well as the Hohonu Range on the south side of the lake.
The only other large permit holder in the area is Reefton Resources, in the Bell Hill area.
The latest application alone covers 252sq km.
So far, Mineralogy has been granted 10 permits throughout New Zealand covering 179,077ha, with a total conservation land overlap of 63,556ha.
If all its applications were granted, its total acreage would make it the largest minerals permit operator in the country.
"Clive Palmer is a mining billionaire, and Australia's fifth richest person. Mining is invasive and can harm biodiversity and ecosystems. It can leave local communities to deal with severe environmental harm and the aftermath of a boom and bust employment cycle," Ms Sage said.
"Companies such as Mineralogy International Ltd should not be able to plunder nature here, especially on conservation land."
Although it has some minerals permits, it does not yet have permission to mine and has not been through a resource consent process.
Greymouth Mayor Tania Gibson said she had not met with Mineralogy personnel, however, they would be welcomed if they "are going to produce jobs and be good for the economy, and sustainable for the environment".
In 2020, Mineralogy manager Vishal Chavan told the Greymouth Star they had an experienced crew of four geologists and would employ a local iwi apprentice as field assistant.
Staff were all New Zealanders and they used local products, services and people where possible.
"They have conducted a low impact grab sampling programme and are reviewing the results," Mr Chavan said.
"We are looking for lithium and rare earth minerals to power the exciting next wave of electric vehicles into the future. This is a long-term plan as lithium demand has been forecast to catch up to production by the mid-2020s," he said.
Mineralogy did not respond this week.
