• Respect for risk capital the investor must win!
• Need to be pragmatic and responsive to shareholder and market $\blacksquare$ requirements, whilst balancing the need for a focused operational direction to ensure a growth path
• The market is the arbiter junior companies should not be spending $\blacksquare$ money on projects if the market is not prepared to replenish the kitty

Theatres of Operation

Kyrgyzstan

• Tradition of uranium mining
• Proximity to major regional processing centre at Kara-Balta
• 20% of known global recoverable resources in the Central Asian region
• Less stringent planning and environmental constraints
• Russian "reserves" of approximately $\blacksquare$ 2,000 t $U_3O_8$ in C1 +C2 +P1
• Advanced exploration conducted by $\blacksquare$ Soviet geologists but limited drilling
• Company income tax rate only 10%

Australia

• Strategy is to identify and acquire world class deposits of uranium and gold mineralisation under cover
• No recycling of sub-economic uranium deposits – targeting large, undiscovered and concealed ore bodies fitting the unconformity and IOCG models
• Over 3,800 sq km of prospective ground in 3 states currently granted or under application
• Highly experienced technical team track $\blacksquare$ record of discovery
• Active ground evaluation and acquisition program underway

Australian uranium/gold prospects MRO Earning 75%

• Granted ELs and applications cover over 3,800 sq km of ground prospective for gold and uranium Jabiluka
• Queensland (IOCG) $\blacksquare$
• Red Bull 1
• Savannah
• Fort Bowen
• Mount Brown
• Northern Territory (U,Au) $\blacksquare$
• Fog Bay
• Compass Creek
• Western Australia (U,Au)
• Coor-de-Wandy Hill
• Yalbra Hills
• Collins Springs
• Granite Hills

Mine-Finding Expertise

• E. Lee Spencer (MSc) 30 years experience mining and exploration in Asia Pacific. Actively involved with gold, diamond and other mineral discoveries and development projects in PNG, Indonesia, Australia and Philippines.
• Mohan Varkey (MSc) 36 yrs uranium/gold exploration and mining $\blacksquare$ experience. Formerly senior exploration geologist for Urangesellschaft, CRA and Idemitsu. Discovery geologist of Narbalek deposit (U), and part of discovery teams for Cigar Lake (U) in Canada, and Ernest Henry (Cu, Au) deposit Australia
• David Bennett (BSc) $-$ 34 years exploration and mining experience. Formerly exploration geologist with Minatome, Mobil Energy Minerals and Urangesellschaft. Former senior exploration geologist for Robertson Research. Independent consultant since 1982.

Iron Oxide Copper Gold (IOCG)

Large ore bodies:

• Cu-U-Au associations
• Olympic Dam/Ernest Henry types
• Breccia type ore bodies in Proterozoic metasediments and volcanics
• IOCG discoveries in the Mt. Isa-Cloncurry region of Queensland include:
• Ernest Henry 167Mt at 1.1% Cu & 0.54g/t Au
• Osborne 15Mt at 3% Cu & 1.3g/t Au
• Selwyn 5Mt at 1.0% Cu & 5.0g/t Au

IOCG Features:

• Proximity to Palaeoproterozoic or Archean basement
• Sedimentation along cratonic margins or intracratonic belts
• Regional metamorphism of sediments and interlaid volcanics
• Volcanism and emplacement of batholiths establishing thermal gradients
• Intrusion of high temperature granitoids leading to brecciation,
  metasomatism, volume reduction and economic concentration of minerals ∎

Queensland - IOCG Targets

The regional magnetic map of Queensland shows a circular magnetic anomaly in the centre in the Millungera area. The centre of the feature is a magnetic low which could represent a granitic intrusion. The areas covered by EPA's are interpreted as Archaean basement highs, and are considered prospective for gold and uranium at the Archaean unconformity, and/or granite contacts.

4 EPA's COVERING 964 SQ KM

Northern Territory: Unconformity Targets

EL 25406 (Fog Bay)

Early Proterozioc gneisses and marbles subcrop to the northeast. The target is unconformity controlled vein-type uranium/gold mineralisation. The Welltree Metamorphics is the dominant lithological unit and is intruded by the Wagaite Granite. The overlying Depot Creek Sandstone provides the classic unconformity model.

EL 25399 (Compass Creek)

The lithological succession is Burrell Creek Formation, Mt Bonney Formation and Gerowie Tuff. This succession has been intruded by Princes Springs Granite, Zamu Dolerite and numerous quartz veins. Exploration will be directed at gold-uranium mineralisation at the granite-sediment interface.

Northern Territory: Unconformity Concept

Western Australia - Unconformity Targets

MONARO ITNING NL

• All areas are situated along the southern margins of the Gascoyne Province
• Archaean and Paleoproterozoic gneisses and metasediments are present
• These are intruded by Paleoproterozoic granites coincident $\blacksquare$ with major structures
• High energy fluviatile and shallow marine sediments of the Mount James Formation unconformably overlie the Paleoproterozoic gneisses and metasediments
• All areas have the potential to host Unconformity related uranium and gold mineralisation

Western Australia -Unconformity Targets

Collins Spring	547 sq km (E09/1331)
Coor-de-wandy Hills	608 sq km (E09/1333)
Yalbra Hill	429 sq km (E09/1336)
Granite Hills	365 sq km (E09/1345)
Total Area	1,949 sq km

The tenements located are entirely within the Gascoyne Basin, and target Proterozoic metasediments of the Mt James Formation which are intruded by Proterozoic late-stage granitoids coincident with major structures.
