Leonora

Mt Stirling  (Earning up to 90%)

The Mt Stirling Project is located 40km northwest of Leonora in Western Australia (Figure 3). The Project lies 8km NW of the Tarmoola Gold Mine (Red5’s King of the Hill), which has produced in excess of 1 million ounces of gold to date. Current unmined resources are believed to be in the order of 3.1 million ounces at an average grade of 1.5 g/t Au.

The Mt Stirling Project is covered by extensive basalt outcrop and sub-crop with minor areas of alluvial cover. The basalt is gently north-dipping and can be divided into predominantly massive basalts in the west and pillowed, variolitic basalts in the east. The massive basalts have been intruded by the Mt Stirling monzogranite, parts of which outcrop on the tenements. Drilling by Torian at the Mt Stirling Project successfully extended the area of the known gold mineralised on the Project (Figure 4).

There are two different styles of gold mineralisation at Mount Stirling:

  • The Mt Stirling mineralisation is accommodated within a northeast dipping sheared mafic (Hi Mag Basalt),
  • Whilst the Mt Stirling Well is hosted by a quartz vein dipping shallowly to the east, fully contained within a granite.

In late 2018, Torian commission independent contractors to estimate the current gold resource contained within the project.  The current inferred Resource for the project is shown in Table 2.

Table 2: Mt Stirling Project Resource Estimation (FEB 2019)
Mt Stirling Project
JORC (2012) Inferred Resources - Gold >0.5 g/t 
     
Deposit Tonnes Gold g/t Ounces
Mt Stirling 727,000 1.45 g/t 33,895
Stirling Well 253,500 2.01 g/t 16,384
Totals 980,500 1.594 g/t 50,279


With these Mineral Resource Estimates, a solid foundation for future growth can be established. In doing so, strike and depth extensions of mineralisation require testing, and infill drilling will need to be undertaken to increase confidence in the current resource. The next round of resource expansion drilling campaigns in the Leonora Region will target these areas, seeking to build the resource base, towards a level that can sustain future mining operations.
