SnapshotIn a tumultuous turn of events, Queensland-based mining company Aurora Metals has collapsed, leaving a trail of debts totaling approximately $170 million. KordaMentha, the appointed administrator, is currently working through Aurora Metals' financial records.

Aurora Metals' collapse came after WA mining services company Emeco (ASX:EHL) took legal action to protect its interests. The company had provided ongoing care and maintenance services to one of Aurora's mothballed mines in Chillagoe, North Queensland.

The company's assets, which include underground mines such as King Vol and Mungana, as well as processing plants at Mt Garnet and Chillagoe, are currently under care and maintenance.

Summary:

The Dry River South Deposit zinc, lead-rich polymetallic orebody is a sheet of massive pyritic sulphides that dips at a shallow angle to the ESE and plunges gently to the SSW. Massive pyritic sulphides lie along, and just below, the upper contact between highly altered felsic volcanics and relatively unaltered hanging-wall metasediments and extend for up to 250 m down-dip and approximately 800 m down-plunge. The orebody reaches a maximum thickness of about 15 m in structurally thickened domains. The orebody is delimited to the west by late faulting and an extensive body of quartz feldspar porphyry. Down-dip and down-plunge limits are defined by a decrease in sulphides. To the north, the DRS orebody is cut by a complex array of late faults including the NE-trending Andesite Fault. This is interpreted to represent the first stage of structural separation of the DRS orebody from the Surveyor orebody, which lies about 600 m to the north. Access is via a portal and decline from the Surveyor Mine open pit.
