Summary:
The Mount Peake deposit is located within outliers of sediments of the Neoproterozoic Georgina Basin, which unconformably overlies units of the Aileron Province, a subdivision of the Palaeoproterozoic Arunta Group.
The mineralisation is hosted within a flat-lying magnetite-bearing gabbro-norite sill, believed to be of Neoproterozoic to Cambrian age that has intruded the older units - drilling has indicated large thicknesses of mineralisation (up to 170m), and exhibits good lateral continuity between drillholes.
The gabbro hosting the mineralisation is part of a 20km long x 10km wide NW trending sill or sill complex, with the mineralisation in the uppermost parts of the sill - the identified JORC- resources are confined to one part of the complex, with other areas yet to be defined, and which provide upside potential.
Summary:
The mining method will be an open pit with conventional drill and blast and load and haul with excavators and large mining equipment. Ore and waste will be trucked to the concentrator and waste dump respectively.
The open pit strip ratio is 1.1:1 (waste: ore). The large size of the orebody (ca. 2000m x 350m x 100m) and gradual grade boundaries allows a low 2% dilution factor to be applied, with ore loss being correspondingly low.

Summary:
Mine Site Beneficiation Plant
The Mount Peake mine site will involve mining of the titanomagnetite ore and recovery of the magnetite in a concentrate through a beneficiation process.
Metallurgical testwork at Nagrom Laboratories (Perth) was co-ordinated by Como with a focus on refining recoveries to match the revised TIVAN® Process Facility feedstock specifications provided by SMS.
TIVAN® Processing Facility
The planned Darwin based TIVAN® Processing Facility will process the magnetite concentrate into three commercial products through well understood pyro and hydro-metallurgical plants.
TNG, together with its consultants, has implemented various improvements on the TIVAN® Processing Facility flowsheet, focusing on improved recoveries and maximising utilisation of proven technology modules.
After extensive refinement, the TIVAN® Process now utilises a proprietary method of vanadium extraction, which avoids the utilisation of l ........
