SnapshotIn a tumultuous turn of events, Queensland-based mining company Aurora Metals has collapsed, leaving a trail of debts.

Aurora Metals' collapse came after mining services company Emeco took legal action to protect its interests. The company had provided ongoing care and maintenance services to one of Aurora's mothballed mines.

Aurora Metals Limited, is the most recent operator of the Mount Garnet, put the site into care and maintenance in 2021.

Aurora Metals was subsequently liquidated and associated mining leases were disclaimed in March 2024. Quensland Government is actively managing the sites under the Abandoned Mine Lands Program since March 2024.

Summary:

The Mt Garnet base metal mineralisation occurs in a garnet-pyroxene-amphibole skarn-altered, northerly-trending, fossiliferous limestone and limey siltstone unit that hosts sphalerite-rich mineralisation. The skarn zone dips sub-vertically, is typically 30 metres to 60 metres wide, and extends beyond 550 metres below surface, which is the current limit of drill investigations.

High-grade massive and semi-massive sphalerite-rich mineralisation (notionally >10% Zn) is largely confined to two distinct, sub-parallel, shallow to moderately north-plunging “shoots”, termed the South Shoot and the North Shoot.
