Torian Resources Ltd (Torian or Company) (ASX:TNR) is pleased to announce that as a part of its strategy to achieve a cash flow from gold production in the near term it has entered into a Tenement Option and Sale Agreement for a tenement that lies to the northeast of the historical Bonnie Vale Gold Mining centre. The Bonnie Vale project is located approximately 10km north of Coolgardie in the Coolgardie Mineral Field.
The Bonnie Vale project consists of a single granted Prospecting Licence 15/5305 with an application to transition to Mining Lease 15/1839 pending. Torian can acquire a 100% interest by paying $71,500 in cash and issuing $27,500 in shares after a 2 month Option period. The vendors, Zetek Resources Pty Ltd and Western Resources Pty Ltd, will retain a 2% gross royalty of any product extracted and recovered. The tenement covers 53Ha.

1 Geology and Mineralisation
1.1 Regional Geology and Mineralisation
The Bonnie Vale Project is located within the Coolgardie Domain of the Kalgoorlie Terrane in the Eastern Goldfields Province of the Yilgarn Craton. This domain consists of an arcuate belt of complexly deformed mafic and ultramafic rocks with minor black shales, volcanoclastics and sediments. Sills and dykes ranging in composition from felsic to mafic intrude the sequence. Granitic rocks intrude and define the western boundary of the Coolgardie Domain while the Zuleika Shear forms the eastern boundary. The Domain has been subjected to lower amphibolite facies metamorphism.
The project area lies in an east-west trending portion of a sedimentary, mafic and ultramafic sequence surrounding the hinge of the north-east trending Bonnie Vale anticline. The Bonnie Vale granite was intruded along the axis of this anticline into ultramafic units that underlie the mafic and sedimentary units. Minor black shales are intercalated with the mafic units. The geology is shown in Figure 2 below.

1.2 Local Geology and Mineralisation
A small open pit runs east- west and exposes weathered mafic rocks in the main part of the pit while sedimentary rocks form the northern wall of the pit. An east-west, steeply north-dipping, strongly sheared contact is evident between these rocks. A 10 to 20 metre thick, sheeted quartz vein is well developed in the mafic unit. It strikes east-west, dips between 0[o] and 30[o] to the north and has an intersection plunge with the shear of about 30[o] to 45[o] to the west.
The previous drilling demonstrated that there is gold enrichment in laterite and ferruginous material near the surface below which mottled zone clays occasional host gold in ferruginous quartz-rich sections while the underlying pallid zone clays rarely contain more than anomalous gold. The better

gold grades lie in semi-weathered rocks at depths of 40 to 50 metres. The depth of weathering appears to be more extensive along the mineralised zone where the shearing and alteration zones are more prone to the effects of weathering. Very little of the drilling carried out to date has tested the mineralisation in fresh rock.
The distribution of the underground workings from the available mine plans, collapsed stope outlines and drilling indicates that the mineralisation, at least to the east of the open pit dips north at 70[o]
West of the open pit the drilling was too shallow and for the most part, was terminated within the pallid zone. Accordingly, it is not particularly useful in guiding further exploration other than indicating that the near surface gold enrichment has a north-west trend.
2 Exploration Activities
2.1 Historical Exploration
Gold was discovered at Bonnie Vale in 1894 and the centre produced 167,582 ounces of gold in the period 1897 to 1911. Much of this production came from outside the new tenement.
Prior to 1910, the initial mining consisted of numerous small-scale shafts and surface diggings. Production records are shown in the table below.
The tenement contains a historical mining centre where a battery operated in the 1930s is estimated to have produced 25,000 tonnes of tailings remaining. Much of this material was sourced from outside the current tenement. Approximately 7,000t of this material has been vat leached. Surface sampling of this material has returned grades in excess of 1g/t Au.

2.2 Recent Exploration
Between 1983 and 1988, Grants Patch Partners and Kalgoorlie Resources NL explored the area using geological mapping, rock chip sampling and drilling 36 RC holes (B001- 036) for 1,028m.
In 1988, Main Reef Gold Ltd investigated the high-grade intersections in the Kalgoorlie Resources drilling by some small-scale underground mining and subsequently a small open pit.
Far Corners Minerals Pty Ltd purchased the tenement and in June 1997-8 drilled 76 RAB holes for a total of 3,073 m. Some of this drilling was on an adjacent tenement.
This drilling located a number of significant intersections were obtained and the geology was better defined.
In 2003 and 2004 a further 19 RC drill holes (1,634m) and 13 aircore holes (500m) were drilled testing the mineralisation deeper than previously. This drilling intersected mixed results, with some old workings being intersected as well as some significant gold grades.
No drilling has been completed since 2004 on this project. The hole details and significant results are tabled below. The drilling, pit etc are shown on the map and cross section below.

About Torian:
Torian Resources Ltd (ASX:TNR) is a highly active gold exploration and development company. The Company has amassed a large and strategic landholding comprising of eight projects and over 500km² of tenure located in the Goldfields Region of Western Australia.
Torian’s flagship project, Zuleika, is located along the world-class Zuleika Shear. The Zuleika Shear is the fourth largest gold producing region in Australia and consistently produces some of the country’s highest grade and lowest cost gold mines. Torian’s Zuleika 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 Evolutions (ASX:EVN) 1.8Moz Frogs Legs and White Foil deposits.
The Zuleika Shear has seen significant corporate activity of late with over A$1 Billion worth of acquisition in the region by major mining companies. Torian’s Zuleika project comprises approximately 223km² of tenure making Torian one of the largest landholder in this sought after region.
Last year Torian drilled 59,345m for a total of 1,319 holes across its projects. The large drilling campaign tested 26 exploration targets and, importantly, made four gold discoveries making Torian one of the most active gold explorers on the ASX.
