On January 17, 2015 Rosslyn Hill Mining Pty Ltd (RHM) initiated steps to place the Paroo Station Lead Mine (Mine) into care and maintenance due to depressed global lead prices and rising concentrate treatment costs.
April 17, 2020 /CNW/ - LeadFX Inc. is pleased to announce InCoR Holdings Limited has agreed to provide $2,000,000 financing for the Company as it plans the restart of operations at its 100% owned Paroo Station Lead Mine in Western Australia as a first phase development. |

Summary:
The project includes five lead deposits – Magellan, Cano, Pinzon in the Magellan Hill area, and Pizarro and Drake in the Finlayson Range south of the Paroo Station Mine. Other small lead mineral occurrences (i.e. Cortez) are present across the local area.
The Paroo Station Mine area contains remnant discontinuous outliers of the Yelma Formation (Earaheedy Basin), forming low hills surrounded by shales of the Maraloou Formation (Yerrida Basin). The informally-named Magellan Hill – a mesa of approximately 5 × 2.5 km rises 25–50 m above the surrounding alluvial plain. A relatively thin (up to 60 m) sequence of the Yelma Formation sediments unconformably overlies the Maraloou shale. The Yelma sequence includes a basal fining-upwards clastic sandstone-siltstone sequence that is overlain by a silcretized quartz-clay collapse breccia with relics of dolostones at the base of the unit. The Yelma Formation is overprinted by surficial massive silcrete several meters thick and a thin colluvial soil.
At the Pizarro and Drake lead deposits south of the Magellan Hill group, lead mineralization occurs in sediments of the Yelma Formation and the underlying Juderina Formation (Yerrida Basin) (Looi, 2010).
The Magellan Hill group of lead deposits – Magellan, Cano and Pinzon – are contained in a mesa outcrop with dimensions of 5 × 2.5 km, comprising the Yelma Formation which hosts the lead mineralization, the majority of which is contained in a quartz-clay brecci ........
Summary:
Ore at the Paroo Station Mine is extracted via drilling and blasting from a series of open pits on Magellan Hill. Excavators are then used to dig and load ore and waste into 85t haul trucks. Ore is mined concurrently from a number of faces to provide a homogenous blend to the concentrator, and ore is stockpiled and further blended on the run of mine (ROM) pad. Grade control is enhanced by testing every blast hole in the orebody and in the near vicinity of the ore body.
Short term planning is based on additional grade control drilling and sampling of blast holes ahead of mining. The waste dumps are located adjacent to the Cano and Magellan pits. The mining has been carried out to date by a mining contractor.
