-
Transaction to proceed without the Taurus and Mt Keith projects as agreements were unable to be settled with the project Vendors in a reasonable timeframe
-
Company to focus on the Mt Stirling and Malcolm projects
-
The projects host an existing Inferred JORC Resource of 37,477 oz Au
-
ASX Listing Rule 11.1.3 will not apply to the transaction meaning Torian is no longer required to re-comply with Chapters 1 & 2 of the Listing Rules
-
Drill program planned to commence immediately following completion of the acquisition
-
Torian shareholders to vote on various resolutions to approve the acquisition at an Extraordinary General Meeting expected to be held following completion of satisfactory due diligence and execution of all relevant transaction documentation
Torian Resources Limited ( Torian or Company ) has entered into an Amendment to the Conditional Heads of Agreement with Cascade Resources Limited ( Cascade ). Following lengthy discussions between Cascade and the Vendors of the Taurus and Mt Keith projects, suitable transaction documentation was unable to be settled in a reasonable timeframe to Torian’s satisfaction. As a result, the Company will proceed with the acquisition of the contractual rights over the Mt Stirling and Malcolm projects only.
A summary of the Mt Stirling and Malcolm projects and the amended terms of the proposed transaction are included below.

-
Mt Stirling Well is a prospect within the Mt Stirling Project.
A detailed summary of the supporting project assumptions and data (Table 1 as per JORC (2012) guidelines) is provided in the Appendix.
Mt Stirling Project
The Mt Stirling Project is located approximately 40 kilometres north west of Leonora. Under the proposed transaction, Torian will acquire a contractual right to acquire 100% of the Mt Stirling Well prospect. Torian will also acquire contractual rights to acquire 51% of the Mt Stirling prospect and 51% of the Mt Cutmore prospect with a right to earn up to 90% of each prospect under the terms of two separate joint venture agreements. The Mt Stirling Project comprises 19 prospecting licences covering an area of 23 square kilometres.
The Mt Stirling Well Prospect has a current JORC compliant Inferred resource of 41,250 tonnes @ 8.54g/t for 11,327oz Au. This resource, whilst inferred, is a high grade, oxidised system, located at surface which the Company believes may be amenable to low cost mining. This resource is open in all directions and further exploration at this prospect is a high priority.
This mineralisation is a flat lying quartz vein hosted in granite. The granite has a diameter of approximately 1 kilometre and there is potential for the current resource to grow significantly. Previous drilling at the prospect occurs over a strike length of approximately 200 metres and there is no drilling deeper than about 40 metres.
==> picture [183 x 36] intentionally omitted <==
Between 1897 and 1913, a small underground mine was active at the Mt Stirling Well prospect. Recorded production from the mine was 3,354 tonnes @ 52.02g/t Au for 5,610 oz’s Au.
Previous exploration at the Mt Stirling Project has focused on a small number of targets defined by old workings. RC drilling was conducted at these targets however they remain open along strike and down dip. The Mt Stirling Project has a number of other targets that have been defined by surface sampling that have not been drill tested to date.
Malcolm Project
The Malcolm Project is located approximately 20 kilometres east of Leonora. Under the proposed transaction Torian will acquire a contractual right to acquire 100% of the Rabbit Warren South prospect and contractual rights to acquire 51% interests in the Mt Stewart, Braemore, Malcolm and Mt George Prospects. Torian has the right to earn up to 90% of each of these Prospects under the terms of various joint venture agreements. The Malcolm Project comprises 54 tenements covering an area of approximately 75 square kilometres.
The Malcolm Project has received only superficial exploration to date, focusing on historic workings. Several reconnaissance RAB holes have intersected anomalous values away from the historic workings. Many of these have not been followed up by RC drilling. In addition JORC Inferred resources have been defined from previous shallow RC drilling. All resources remain open along strike and also at depth.
Other targets have been defined from previous soil geochemical sampling and areas of gold nuggets being found at or very near surface. Most of these areas have never been drill tested.
Resource Parameters
-
Geology and geological interpretation – the drillholes were geologically logged noting various features such as rock type, alteration, veining, and oxidation. Mt Stirling Well is a flat lying quartz vein hosted by a granite. Mt Stirling is a typical steep dipping shearzone in basalts. Malcolm is hosted by sheared black shales. All zones of mineralisation outcrop at surface and have had shallow historic minor mining dating from the 1890s. Further details are described above.
-
Sampling and sub-sampling techniques – sampling was via riffle split from original bulk samples collected at the drill sites during drilling. Sub-sampling was again via riffle splitting in independent laboratories with typically 50 grams used for routine fire assay.
-
Drilling techniques – only reverse circulation (RC) drilling was used in the resource estimates.
==> picture [183 x 36] intentionally omitted <==
-
The criteria used for classification, including drill and data spacing and distribution – at Mt Stirling Well the drill spacing is 40m by 40m; at Mt Stirling it is variable ranging from 10m by 10m to 10m by 50m; at Malcolm the drill spacing is 20m by 20m. All the resources were classified as Inferred.
-
Sample analysis method – all analysis is via 50 gram fire assay, with routine standards and blanks inserted for quality control.
-
Estimation methodology – Mineralised zones were interpreted on cross sections and digitized outlines created in Micromine software. These were in turn developed into 3 dimensional wire frames encapsulation the mineralisation as interpreted. Drill weighted averages (grade multiplied by width) was used to determine the grades within a wireframe, with discrete higher grade zones (typically +10g/t Au) determined separately.
-
Cut-off grade, including the basis for the selected cut-off grade – a lower cutoff of 1g/t Au was used as a first pass. Top cuts reflect values below the 97[th] percentile of statistical distribution of the values above 1g/t Au.
-
Mining and metallurgical methods and parameters, and other material modifying factors considered to date – all resources were shallow, and actually are exposed on the surface. This being the case open pit mining was assumed, typically with a maximum depth of the top of fresh rock (commonly approximately 40m depth). An exception was at Mt Stirling where the mineralisation is known from previous drilling to persist to at least 120m depth. No metallurgical issues were noted in previous shallow historic mining activities in these areas and so none are expected. All resources remain open at depth and commonly along strike. The maximum extrapolation in areas of no drilling was 40m.
Amended Heads of Agreement:
The key terms of the Amended Heads of Agreement are outlined below:

Pro Forma Adjustment Notes:
-
Recognition of net cash with the below adjustments and inclusive of cash raised of $1.72 million ($2 million net of costs of raising share capital). Additional funds of $300,000 anticipated to be recovered by way of tenement sales and recoupment of rehabilitation bonds (see note 6). Reductions in cash relate to $295,000 vendor payments and reductions to repay loans (see Note 4);
-
Exploration assets purchased by way of issue of shares to purchase contractual rights owned by Cascade, and cash and share issues to exercise the options, which are all costs associated with acquiring the underlying tenements;
-
Net $100,000 accrued liability reduction as a result of prior scrip issues which will discharge part of accrued Directors fees and rental owed to related parties;
-
Reduction of loans payable to related and third parties on the following basis:
-
a. $20,000 interest payable to ROC Salt Limited discharged by cash;
-
b. $198,216 payable to former Director Mr Peter Ashcroft/his related entities discharged by share issue;

c. $88,958 loan payable inclusive of interest to be repaid in cash;
-
Issue of capital to reflect the acquisition and exercise of contractual rights in addition to all agreed conversions of debt or trade payables;
-
Reduction in carried forward losses to account for receipt of an estimated $214,000 in rehabilitation bonds on transfer/surrender of tenements ($300,000 less Acquisition Costs of $86,000). Note that in prior audited financial statements auditors recommended the write off of these bonds and they were impaired however the company has a track record of recovering these bonds and they are highly likely to be received. On receipt the impairment will be reversed and will result in a net favourable reduction in carried forward losses.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Commentary | Commentary | |
|---|---|---|
| | All data and results referred to in this report are historic, and date from the | |
| late 1980s to the present day. This data has been judged to be reliable | ||
| | following independent t research, including discussions with previous operators and explorers in person. Samples were collected via Rotary Air Blast (RAB) and Reverse Circulation (RC) drill chips. A minor number of diamond drillholes (DD) were drilled at |
|
| Malcolm. | ||
| | All drilling yielded samples on a metre basis. RAB drilling samples were | |
| commonly composited into intervals of 4 or 5m, with selected individual or | ||
| 2m resamples collected. Reverse Circulation (RC) drilling is utilised to obtain 1 m samples which are riffle split, from which approx. 2-3 kg is pulverised to produce a 50 g charge for fire assay. Diamond core is sawn in half before crushing, pulverising and assaying. |
||
| | Sample preparation method is total material dried and pulverized to | |
| nominally 85% passing 75 µm particle size. Gold analysis method is | ||
| generally by 50g Fire Assay, with Atomic Absorption Spectrometry (AAS) | ||
| finish (DL 0.01 – UL 50 ppm Au). Samples exceeding the upper limit of the | ||
| method were automatically re-assayed utilizing a high grade gravimetric | ||
