Table 2: Mt Stirling 1680N Significant Intercepts from recent Central Phase 1 drilling
Torian’s Executive Director Mr Peretz Schapiro said “As we have been saying for some time, the geology at Mt Stirling has indicated to us that the gold system there is much larger than what was originally defined. Earlier this week we continued to affirm this assumption with the discovery of the eastern mineralised zone.
Today we take another important step in this direction with the results from the NW confirming that we are unearthing a giant, much larger system than we had previously anticipated. Importantly, the system still remains open to the NW, and we eagerly await further results from this domain as we continue to expand this system.
The discovery of this significantly mineralised gold lode in the NW (now to be referred to as the Viserion Lode) confirms that the recently defined (pXRF) arsenic leaking structures (ASX announcement 03/02/2021) were an excellent indicator to vector in on gold mineralisation, confirming our hypothesis at the time. This gives us great confidence in our regional target generation strategy and in the geological and structural interpretation from our Senior Geologist Claudio Sheriff-Zegers. As such, we have expanded our field team and boosted our man-power to fast-track regional assessment and enhance further target generation. Torian has honed its exploration methods to prioritise over 200 targets, ensuring a pipeline of quality targets which will pave the way for further discoveries.
Furthermore, this significant discovery gives us the confidence to seamlessly continue the drilling campaign at Mt Stirling. Further assays will continue to confirm the breadth and predictability of the gold system, enabling Torian to proudly state that the drilling program has advanced to ‘on-going’ for the remainder of 2021.
Additionally, the current round of results received from Mt Stirling continues to add considerable tonnage and ounces which will significantly increase the global scale and grade of the resource.
We are additionally encouraged by what looks to be a significant continuation of the predicted gold system at depth, with our diamond drillers encountering significant Viserion lode material adding a further ~120m extension to the resource.
Should results confirm our interpretation of a shear-hosted gold system that continues at depth, for considerable down-dip depth, it would mean that Mt Stirling’s multiple gold structures continue to have the potential to depth and resemble that of regional operating gold mines e.g
==> picture [79 x 30] intentionally omitted <==
St Barbara’s (ASX:SBM) 4.8Moz Gwalia Mine and Saracen’s (ASX:SAR) 3.8Moz Thunderbox Mine, given it remains open in all directions.
The ongoing flow of high-grade results intercepted during our drilling campaign continues to justify our confidence in Mt Stirling, in that it is a much larger gold system than originally defined, with the system now exceeding 680m of strike and ~250m at depth. We anticipate that further results from our on-going drilling program will continue to intercept economic grade gold as we have demonstrated that we are ‘on the system’.
In addition to extending the strike, Torian’s drilling has also intercepted grade above earlier reported historical drill hole intercepts which were used in the Company’s previous resource estimate. All the above (increase in strike, depth, and historical grade) gives us great confidence that when our interim resource is completed in the first quarter of this year, will result in a significant upgrade to our tonnage and gold ounces.
2021 is shaping up to be an exciting year for our Company as we anticipate significant news flow over the coming weeks and months. We eagerly await the results from an additional 11 drillholes from Phase 1 of the Mt Stirling program, along with results from 18 drillholes at Stirling Well, 21 exploratory drill holes at Diorite and the results from Phase 2 and the continuing phase 3 at Mt Stirling which now includes extensional diamond drilling.”

About Torian:
Torian Resources Ltd (ASX: TNR) is a highly active gold exploration and development company with an extensive and strategic land holding comprising six projects and over 400km² of tenure in the Goldfields Region of Western Australia. All projects are nearby to excellent infrastructure and lie within 50km of major mining towns.
Torian’s flagship Mt Stirling Project is situated approximately 40km NW of Leonora, and neighbours Red 5’s Kind of the Hills mine. The region has recently produced approximately 14M oz of gold from mines such as Tower Hills, Sons of Gwalia, Thunderbox, Harbour Lights and Gwalia.
The Mt Stirling Project consists of 2 blocks:
-
The Stirling Block to the north which contains two JORC Inferred resources.
-
a. Mt Stirling – 727,000t at 1.45 g/t Au for 33,900oz
-
b. Stirling Well – 253,500t at 2.01 g/t Au for 16,384oz
-
The Diorite Block to the south, home of the historic 73 g/t Diorite King Mine.
The Mount Monger goldfield is located within the Kalgoorlie terrane subdivision of the Eastern Goldfields Province. This 3,700-hectare project lies within close vicinity of Silver Lake Resources Ltd’s (ASX: SLR) key asset, the Mount Monger Gold Camp, a prolific part of the Eastern Goldfields district of Western Australia. The Mount Monger Camp had produced more than 1.67Moz in the last 30 years, and more than 330,000 ounces for Silver Lake in in the last 24 months alone.
The project consists of two distinct areas:
-
The Wombola Block to the north
-
The Mt Monger South Block to the south
The Company is now actively pursuing a proposed spin-off of the Mt Monger and Gibraltar Projects, which proposes that Torian will hold approximately 10% of the new listed entity plus a 20% free carried JV interested in the projects.
Another project in the Kalgoorlie region is the Zuleika project in which the Company is involved in a JV with Dampier Gold Ltd (ASX: ZAG). The Zuleika project is located along the world-class Zuleika Shear, which is the fourth largest gold producing region in Australia and consistently produces some of the country’s highest grade and lowest cost gold mines. This project lies north and partly along strike of several major gold deposits including Northern Star’s (ASX: NST) 7.0Moz East Kundana Joint Venture and Evolution’s (ASX: EVN) 1.8Moz Frogs Legs and White Foil deposits.
Torian’s other projects within the Kalgoorlie region include the Bonnie Vale and Gibraltar Projects, and its Credo Well JV with Dampier Gold Ltd (ASX: ZAG), host of a JORC Inferred resource of 86,419t at 4.41 g/t Au for 12,259 oz.

Mt Stirling Project: JORC Table 1
Section 1 ‐ Sampling Techniques and Data
| Criteria | Commentary |
|---|---|
| Sampling techniques | Drilling results reported are from previous and current exploration completed by Torian Resources Ltd and historical explorers including the original vendors of M37/1306, North Ltd, Dominion Mining Limited and Tern Minerals Ltd. Reverse circulation drilling was used to obtain 1m split samples from which 2‐3kg was pulverised to produce a 500g tub for Photon assay. Sampling has been carried out to company methodology and QA/QC to industry best practice. Zones of interest were 1m split sampled, and comp spear sampling was carried out on interpreted barren zones. Samples were dispatched to MinAnalytical in Kalgoorlie were prep included sorting, drying and pulverisation for a 500gm Photon Assay (PAAU02) |
| Drilling techniques | Historical drilling techniques include reverse circulation (RC) drilling. Standard industry techniques have been used where documented. Current RC drilling was carried out by PXD and Orlando utilising a Schramm truck and track mounted rig respectively. The more recent RC drilling utilised a face sampling hammer with holes usually 155mm in diameter. |
| Drill sample recovery Logging |
Drill recovery has not been routinely recorded on historical work, and is captured for all recent drilling |
| Geological logs are accessible and have been examined over the priority prospect areas. The majority of the logging is of high quality and has sufficiently captured key geological attributes including lithology, weathering, alteration and veining. Logging is qualitative in nature, to company logging coding. All samples / intersections have been logged. 100% of relevant length intersections have been logged. |
|
| Sub‐sampling techniques and sample preparation |
Standard industry sampling practices have been undertaken by the historical exploration companies. Appropriate analytical methods have been used considering the style of mineralisation being sought. Sample sizes are considered appropriate. |
| QC/QC data is absent in the historical data with the exception of the more recent Torian drilling, where sample standards and blanks are routinely used. |
Page 14 of 18 / 19 February 2021
| In the more recent Torian drilling duplicate samples (same sample duplicated) were commonly inserted for every 20 samples taken. Certified Reference Materials (CRM's), blanks and duplicates, are included and analysed in each batch of samples. There is a significant amount of coarse gold at the Mt Stirling Well Prospect. This is reflected in the poor repeatability of some samples and was also noted on the drill logs. |
|
| Quality of assay data and laboratory tests |
The historical drill sample gold assays are a combination of Fire Assay and Aqua Regia. The assay techniques and detection limits are appropriate for the included results. Various independent laboratories have assayed samples from the historical explorers drilling. In general they were internationally accredited for QAQC in mineral analysis. No geophysical tools have been used to date. The laboratories inserted blank and check samples for each batch of samples analysed and reports these accordingly with all results. Samples were analysed for gold via a 50 gram Lead collection fire assay and Inductively Coupled Plasma optical (Atomic) Emission Spectrometry to a detection limited of 0.005ppm Au. Intertek Genalysis routinely inserts analytical blanks, standards and duplicates into the client sample batches for laboratory QAQC performance monitoring. The laboratory QAQC has been assessed in respect of the RC chip sample assays and it has been determined that the levels of accuracy and precision relating to the samples are acceptable. |
| Verification of sampling and assaying |
The historical and current drill intercepts reported have been calculated using a 0.5g/t Au cut‐off, with a maximum 2m internal waste. Twinned holes have been completed to verify repeatability of sampling and assaying used to date. Documentation of primary data is field log sheets (handwritten) or logging to laptop templates. Primary data is entered into application specific data base. The data base is subjected to data verification program, erroneous data is corrected. Data storage is retention of physical log sheet, two electronic backup storage devices and primary electronic database. |
| Location of data points | Drill hole collarswere located using a handheld GPS system. The coordinated are stored in a digital exploration database and are referenced to MGA Zone 51 Datum GDA 94. Location of the majority of the historical drill holes has been using a handheld GPS system, or local grids that have been converted to MGA Zone 51 Datum GDA 94. Survey control used is handheld GPS for historic holes and The more recent Torian drilling has been located utilising a differential GPS and the majority of these holes have been surveyed downhole. |

| Data spacing and distribution | The historical drill spacing is variable over the project as depicted on map plan diagrams. Drill spacing over the more advanced Mt Stirling and Mt Stirling Well Prospects varies from 40m by 40m to 20m by 20m respectively. Sample compositing has been used in areas where mineralisation is not expected to be intersected. If results return indicate mineralisation, 1m split samples were submitted for analysis. |
| Orientation of data in relation to geological structure |
The orientation of the drilling is approximately at right angles to the known mineralisation trend and so gives a fair representation of the true width of mineralisation intersected. No sampling bias is believed to occur due to the orientation of the drilling. |
| Sample security | Drill samples were compiled and collected by Torian employees/contractors. All sample were bagged into calico bags and tied. Samples were transported from site to the MinAnalytical laboratory in Kalgoorlie by Torian employees/contractors. A sample submission form containing laboratory instructions was submitted to the laboratory. The sample submission form and sample summary digitised records were compiled and reviewed so as to check for discrepancies. |
| Audits or reviews | Areview of historical data over the main Mt Stirling and Mt Stirling Well Prospects has been undertaken. The QA/QC on data over the remainder of the project tenements is ongoing. |

| Geology | The Mt Stirling Project tenements are located 40 km northwest of Leonora within the Mt Malcolm District of the Mt Margaret Mineral Field. The project tenements are located within the Norseman‐Wiluna Greenstone Belt in the Eastern Goldfields of Western Australia. The project tenements cover a succession of variolitic, pillowed high Mg basalts that have been intruded by the Mt Stirling syenogranite/monzogranite. Historical prospecting and exploration activities have identified areas of gold mineralisation at the Mt Stirling and Mt Stirling Well Prospects. The orogenic style gold mineralisation appears in different manifestations at each of the prospects. At the Mt Stirling Prospect gold mineralisation is associated with zones of alteration, shearing and quartz veining within massive to variolitic high Mg basalt. The alteration zones comprise quartz‐carbonate‐sericite‐pyrite+/‐ chlorite. At the Mt Stirling Well Prospect gold mineralisation is associated with millimetre to centimetre scale quartz veining within the Mt Stirling syenogranite/monzogranite. The gold mineralised quartz veins have narrow sericite/muscovite‐ epidote‐pyrite alteration selvages. The characteristic of each prospect adheres to generally accepted features of orogenic gold mineralisation of the Eastern Goldfields of Western Australia. |
| Drill hole Information | The location of drill holes is based on historical reports and data originally located on handheld GPS devices. Northing and easting data for historic drilling is generally within 10m accuracy. Recent Torian RC drill holes located with differential GPS. Northing and easting on current Feb 2021 drilling is ± 3m accuracy. No material information, results or data have been excluded. |
| Data aggregation methods | Best gold in drill hole was calculated by taking the maximum gold value in an individual down hole interval from each drill hole and plotting at the corresponding drill hole collar position. Individual downhole intervals were mostly 1m, but vary from 1m to 4m in down hole length. |
| In relation to the reported historical drill hole intersection a weighted average was calculated by a simple weighting of from and to distances down hole. The samples were 2m down hole samples. No top cuts were applied. The current drill hole intersection is reported using a weighted average calculation by a simple weighting of from and to distances down hole at 1m intervals per sample. |

| The historical drilling intercept reported has been calculated using a 1g/t Au cut off, no internal waste and with a total intercept of greater than 1 g/t Au. No metal equivalent values are used |
|
| Relationship between mineralisation widths and intercept lengths |
The orientation of the drilling is approximately at right angles to the known trend mineralisation. At Mt Stirling Well the gently dipping nature of the mineralisation means that steeply inclined holes give approximately true widths. At Mt Stirling the steep dip of the mineralisation means that drill widths are exaggerated. Down hole lengths are reported, true width not known. |
| Diagrams | The data has been presented using appropriate scales and using standard aggregating techniques for the display of data at prospect scale. Geological and mineralisation interpretations based off current understanding and will change with further exploration. |
| Balanced reporting | Historical Torian drilling at the Mt Stirling and Mt Stirling Well Prospects has been reported in TNR:ASX announcements dated: 16/05/2019, 25/02/2019, 23/11/2016, 18/11/2016, 20/09/2016, 03/03/2016. |
| Other substantive exploration data | Geological interpretations are taken from historical and ongoing exploration activities. Detailed historical exploration with the existing Mt Stirling and Mt Stirling Well Prospects has provided a reasonable understanding of the style and distribution of local gold mineralised structures at these prospects. Other areas outside of the existing Mt Stirling and Mt Stirling Well prospects are at a relatively early stage and further work will enhance the understanding of the gold prospectivity of these areas. |
| Further work | A review of the historical exploration data is ongoing with a view to identify and rank additional target areas for further exploration. The results of this ongoing review will determine the nature and scale of future exploration programs. Diagrams are presented in this report outlining areas of existing gold mineralisation and the additional gold target areas identified to date. |
