(As Anticipated 14/11/2005)
BFS Highlights
- Bankable Feasibility Study (BFS) completed, with positive results, encouraging
the Company to proceed with mine development, subject to Government approvals, formalisation of off-take contracts and Board approval of funding arrangements
- Initial capital costs of A$108 million, inclusive of mine development costs of
A$26 million
- Financial modeling of the Project has been based on a sales mix of fines (70%)
and lump (30%), producing total revenues of A$1.4 billion over the nine year life of the mine
- Operating cash surplus of A$583 million (EBITDA) over the nine year life of the
project
- The project returns, based on 29.1 million tonnes of saleable ore, a net present
value (NPV) of A$217 million (before interest and tax) at a 10% discount rate, with an Internal Rate of Return (IRR) of 39.7%
- First shipment of iron ore scheduled to commence in second half of 2006
- BFS takes no account of exploration upside of the Koolan Island Project

History – Pre BHP
- Ore deposits on Koolan and Cockatoo Islands
discovered in 1880
- First mining leases granted, small scale mining
commenced 1907
- First attempt at large scale mining in 1936 when Yampi
Sound Mining Company (a consortium including Nippon Mining Co) announced intention to export to Japan
- Federal Government embargo on all iron ore export in
1938
- First ore mined on Koolan fed small charcoal-iron plant
built by State Government in 1945
- BHP granted leases in 1951
The BHP Years 1965 - 1993
- By the conclusion of mining in 1993, 68Mt ore had been
produced
- Shipment grade declined from >67%Fe for the early Main
pit production to 65% - 65.3%Fe for the final blend
- On closure, all infrastructure removed or buried,
stockpiles and roads ‘moonscaped’ and the Main pit
- pened to allow ingress of the sea
The Aztec Era
- Aztec granted tenements in 2003
- Notice of Intent approved January 2004, drilling
commenced February 2004
- Camp established on Koolan Island August 2004
- Data collection for BFS completed February 2005
- Land Access Agreement negotiations commence with
Traditional Owner’s March 2005
- BFS completed August 2005
Koolan Island
Mine & Infrastructure Layout
Mining Operations
- Contractor-based operation
- Conventional open-pit operation, rotary drills, 200t
hydraulic backhoes, FEL’s, rear dump trucks and ancillary plant
Transportation System
- Truck haulage to ROM pad, primary crusher and
stockpiles
- Conveyor to shipping stockpile
- FEL reclaim from shipping stockpile
- Conveyor to sampling station, wharf and shiploader
Port Facilities
- Steel-pile wharf able to accept Panamax vessels up to
75,000 dwt
- Berth pocket 16m draft
- Fixed, luffing shiploader, capacity 3,000tph
- 20m minimum draft in departure channel - no dredging
required
- Vessel berthing/departure assisted by tugs
Regional Geology
- Kimberley Basin is a large structural basin occupying
most of the Kimberley region with sediments of Lower- Mid Proterozoic age dominant
- The Yampi ore bodies lie at the western end of the NW –
SE trending King Leopold Mobile Zone which forms the south western border of the Kimberley Basin
- Hematite concentration occurs in the basal Yampi,
member of the Pentecost Sandstone in the Kimberley group
Local Stratigraphy
Pentecost Sandstone
White well sorted quartz sandstone, grey siltstone
Yampi Member
Pink-brown arkose and feldspathic sandstone; minor siltstone, hematitic quartz sandstone, glauconitic sandstone
Iron ore Elgee Siltstone
Red-brown and grey sitstone and minor phyllite; thin sandstone interbeds Basal boulder to pebble conglomerate
Warton Sandstone
White well-sorted quartz sandstone and feldspathic sandstone; siltstone interbeds; andalusite granofels in places.
- The Kimberley Group comprises
essentially a succession of sandstones, quartzite's and siltstones, with some interbedded phyllite, unconformably overlying the Speewah Group
- The stratigraphy on Koolan Island
comprises the Warton sandstone, Elgee Siltstone and Yampi Member
- f the Pentecost Sandstone
(distinguished by its hematite content)
