Torian Resources Limited (TNR:ASX) is pleased to announce the first results from the current RC drilling programme at Mt Stirling Well.
The initial round of 48 holes were designed to step out laterally from the area previously drilled to determine the strike extent of the mineralisation. No holes to date have been drilled deeper than 72m.
Drilling is continuing, with approximately 2,431m completed to date. A further 1,330m of drilling is in the process of being completed as part of the Phase 1 program.
The remaining Mt Stirling drilling program is expected to be completed in October 2016.
2. Mt Stirling
The Mt Stirling Project is located 40km northwest of Leonora in Western Australia. The Project lies 8km NW of the Tarmoola Gold Mine, which has produced in excess of one million ounces of gold to date.
Current unmined resources at Tarmoola are believed to be in the order of 2.5 million ounces at an average grade of 5.3 g/t Au. The location of the Mt Stirling Project can be seen in Figure 1 below.

Figure 1: Torian’s Mt Stirling and Malcolm Projects in relation to regional deposits and geology.
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.

Figure 2: Torian’s Mt Stirling Project, tenure, drilling and geology.
The project area is located in the hinge zone of the gently north-plunging Tarmoola anticline. The greenstone sequence is suggested to overlie a major detachment fault separating a granite gneiss complex (Leonora Batholith) from the overlying greenstones. This detachment fault hosts the 7.2 million ounce Sons of Gwalia gold deposit at Leonora.
In the west of the project area are massive predominantly unaltered basalts intruded by the Mt Stirling monzogranite. In the east is a succession of variolitic, pillowed high Mg basalts that contain differentiated dolerite/gabbro sills. These two basalt lithotypes are divided by a central shear zone which trends ~310-330º and consists of chlorite ± tremolite/actinolite schist with narrow quartz veins. Widely spaced sinistral shear bands trending 300-320º overprint the main foliation within the shear zone. Some quartz veins are conformable with the sinistral movement indicated by the shear bands.
The main, well developed, steep (65-80º) east-dipping fabric locally contains a well-developed sub horizontal mineral lineation. Some minor chlorite, silica and pyritic alteration is observed within the shear zone. The Mt Stirling granitoid outcrops in the northeast corner of P37/8008. Finer grained phases are present on the pluton margins especially in the east. Extensive millimetre to centimetre scale quartz veining is present with sericite-muscovite-epidote-pyrite alteration selvages adjacent to many veins. Alteration however is not pervasive and only associated with veining. Multiple quartz vein sets occur as local stockwork arrays.

Numerous felsic dykes and plugs are observed throughout the area with most dykes trending broadly north (340-030º), with less common dykes trending broadly east-west. Some of the dykes may be associated with deeper intrusive bodies which are interpreted to exist from aeromagnetic/gravity data.

3. Drilling Program
As advised to shareholders on 25 July 2016, Torian’s drilling program for FY2017 will see exploration targeted in two areas of mineralisation identified at the Mt Stirling Project, with approximately 5,000m of infill and extensional RC drilling. It is anticipated that results from this programme will be used to define the mineralised areas, resulting in the calculation of a JORC compliant Resource.
Additionally, a 3,000m RAB programme has also been planned to determine if mineralisation exists at the granites/greenstone contact to the north of Mt Stirling Well.
The majority of the holes assayed to date were drilled vertically to intersect the relatively flat lying vein. One hole was drilled at -60 to intersect the vein beneath historic workings. Some holes have intersected steep dipping veins that warrant further drilling using angled holes.
Results greater than 1g/t Au, returned from the first batches submitted to the laboratory are shown in Table 1 below.

Table 1: Results from RC Drilling greater than 1g/t Au at Mt Stirling
Several of the holes intersected values between 0.5 and 1g/t Au. The planning of additional step out drilling is nearing completion. The objective will be to test the area between 80m and 100m depth.

4. Interpretation
Based upon the assays received to date, Torian’s preliminary interpretations are:
-
the discovery of steeper veins requires further investigation;
-
there appear to be subtle variations in the dip of the main flat lying veins, alternatively there may be small fault offsets that disrupt the vein locally; and
-
Mt Stirling Well continues to grow with mineralisation open in all directions.
Geological interpretation is showing the granite intrusion to be more complex than previously understood. This added complexity is encouraging and suggests potential for additional mineralisation styles to be present away from the main vein structure.
5. Next Steps
Over the next two months Torian plans the following at the Mt Stirling Project:
-
Complete Phase 1 of the step out RC drilling;
-
Commence a limited phase 2 RC drilling programme to test several areas down to depths of approximately 100m vertical; and
-
Carry out an interpretation of all results received and plan further work.
When drilling is complete at Mt Stirling Well the rig will move to Mt Stirling to test an area of mineralisation historically identified to be present within a steeply dipping shear zone contained within a basaltic host.
6. Commentary
Torian’s Managing Director, Matthew Sullivan comments:
“These results are very encouraging. They exceed Torian’s expectations by a significant margin. Further drilling will define the mineralisation over a larger area. The location of steeper veins is also good news and may lead to a reappraisal of the mineralisation”.
Geological interpretation is showing the granite intrusion to be more complex than previously understood. This added complexity is encouraging and suggests potential for additional mineralisation styles to be present away from the main vein structure. “

About Torian:
Torian Resources Ltd ( ASX:TNR ) is a highly active Australian gold company that is focused on developing the gold mines of tomorrow. The Company has four advanced projects located in the Goldfields region of Western Australia.
Torian’s flagship Project, the Zuleika JV, lies north and partly along strike of several major gold mines including Northern Star (ASX:NST), Tribune Resources (ASX:TBR) and Rand Mining’s (ASX:RND) 7Moz East Kundana Joint Venture and Evolution’s (ASX:EVN) Frogs Legs and White Foil operations.
Since May 2015, Torian has increased its landholding at the Zuleika Project by approximately 86% via eight separate acquisitions. Torian is now the second largest landholder in this highly sought after region and is focused on fast tracking its development.
Torian has commenced a large, 4 Phase, exploration program that is targeting the Zuleika Shear and intends to further consolidate ground in this region.
Torian is also developing the high grade Mt Stirling Project which has an outcropping inferred resource located 40km northwest of Leonora. Following a successful infill drilling program in December, Torian is currently completing an internal economic study on the project to assess it as a standalone mining operation.
Torian’s exploration team has an enviable track record of discovering and developing a number of multi-million ounce gold mines in this region. Torian is commencing an exciting phase in its development and we look forward to updating the market as things progress.
