The Company's 5% interest in the Bigrlyi Uranium Joint Venture, which is a pre-development mineral project, is classified in the accounts as "Investment in Joint Venture". The Bigrlyi project is located in the Ngalia Basin, approximately 390 km northwest of Alice Springs, in the Northern Territory. The project is characterised by relatively high uranium grades (with vanadium credits) and excellent metallurgical recoveries.
The Bigrlyi Uranium Joint Venture is an important asset which Southern Cross first acquired in 1981 in a purchase from the Commonwealth Atomic Energy Commission in a joint venture with a number of other companies. The project was subject to significant exploration activity in the period 1974 to 1982 and then remained on a care and maintenance basis for many years. Energy Metals Ltd (EME) obtained a majority interest in the project in November 2005 and became Operator.
EME, which is now 60% controlled by one of the largest Chinese nuclear power companies (China Guandong Nuclear Power Holding Co Ltd, holds a 53.3% interest and Paladin Energy Ltd (PDN) (through a subsidiary) holds 41.7%.
The following material is compiled from information provided in the latest Annual Report of the Operator, Energy Metals Ltd (EME):
Several drilling programmes have been completed at Bigrlyi since 2005, with most holes intersecting significant uranium mineralisation. Uranium and vanadium resource models were successively calculated incorporating results from these drilling programmes, with an updated resource estimate (summarised below) released in July 2010. The resources were estimated by consultants Hellman & Schofield (H&S) using the Multiple Indicator Kriging (MIK) method to estimate uranium resources and Ordinary Kriging (OK) to estimate vanadium resources.
At a cut-off grade of 500ppm U3O8 the Bigrlyi resource totals 22.4 million pounds of U3O8 and
24.7 million pounds of V2O5, with 60% of the contained uranium metail currently reporting to the Indicated Resource category.
At a cut-off grade of 250ppm U3O8 the Bigrlyi resource totals 28.8 million pounds of U3O8 and
36.8 million pounds of V2O5.

Detailed metallurgical testwork undertaken as part of previous scoping studies has confirmed the very high dissolution characteristics of the Bigrlyi ore, with extraction rates of 98% uranium and
59% vanadium recorded from base case acid leach tests and 94%-95% vanadium and 45% vanadium under optimum leach conditions.
Activities undertaken by the Operator in the last half of the year were designed to collect sufficient data to enable completion of a Pre-Feasibility Study (PFS), as well as further expand the resource base at Bigrlyi. All site-based technical inputs required for the PFS were obtained by the end of the year, and the PFS remains on track for completion in the first half of 2011.
Further drilling programmes (both RC and diamond drilling) were commenced mid-July, after delays caused by unseasonal heavy rainfall. Data from that drilling are being compiled, with an upgraded resource estimate expected by mid-2011.
Activities at Bigrlyi during the 2011 field season will depend partly on the results of the PFS due
mid-2011, with the joint venture likely to approve commencement of a full feasibility study (FFS) should the PFS be positive. However, regardless of the results of the PFS, drilling to increase the resource base at Bigrlyi is expected to recommence early 2011, and metallurgical and engineering studies aimed at identifying opportunities to further improve project economics and de-risk the project will continue throughout the period.
Information above relating to exploration results, data and cut off grades is based on information compiled by Mr Paul Dunbar and Mr Lindsay Dudfield, of Energy Metals Ltd (Operator). Both Mr Dunbar and Mr Dudfield are members of the AusIMM and the AIG. Mr Dunbar is a full time employee of Energy Metals and Mr Dudfield is a consultant to Energy Metals. They both have sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which they are undertaking to qualify as a Competent Person as defined in the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves – The JORC Code (2004)”. Mr Dunbar and Mr Dudfield have both consented to the inclusion of the information in the form and context in which it appears.

Other Investment Activities
Southern Cross has for many years invested surplus funds in property, shares and other investment projects.
An investment of $500,000 was made some twenty years ago whereby the Company became a 50% joint first mortgagee over freehold beachfront land at Nadi, Fiji. This investment opportunity was provided by the Chairman who, together with other associated interests, retained the other 50% of the mortgage.
The Company also has a 20% shareholding in the Fijian company which is the registered proprietor of the properties. The freehold land is zoned for Special Uses, related to tourism activities. It is suitable for the development of about 700 holiday apartments and for hotels.
As the Company is a joint mortgagee as well as a joint substantial shareholder in the Fijian company, its interests are closely aligned with the other shareholders and mortgagees. Whilst there may be a view that conflicts of interest could have arisen, all parties are reviewing the strategy for this investment on a regular basis to ensure a transparent process is followed, as well as ensuring that the approach taken maximises the potential return, despite the delays due to political upheavals that have occurred in Fiji in recent years.
As the acquisition returned 230% on $500,000 invested within the first three years, the Directors consider that this investment has already provided a very good return. The book value is comprised of the balance of the revalued figure and the accrued interest thereon.
The Company holds strategic investments in two listed entities - Longreach Oil Ltd (LGO) and Chapmans Ltd (CHP). LGO is concentrating on Oil and Gas, Coal and other Energy exploration. CHP has been operating on a small scale in investment projects, provision of venture capital and general investment. CHP also has a subsidiary company, Hallmark Minerals N L in which it holds about 70% and in which Southern Cross has a 20% shareholding. Hallmark Minerals has recently been re-activated and has invested in a coal mining project in Kalimantan, Indonesia and is also seeking to participate in other mineral exploration and development projects. |
