OVERVIEW
Legend has had a productive quarter against the backdrop of continuing uncertainty in financial markets and lack of interest and confidence in the exploration equity market specifically.
The Pilbara Project rockchip sampling programme, conducted in October with results announced to the market on 20 November, has added a magnetite iron ore dimension to this project. Given the proximity of the project to existing infrastructure and other complimentary projects this has certainly “value added” to the project.
Many new project opportunities have been and continue to be reviewed by the Executive Management Team and associated consultants. The state of the markets, make capital raising for exploration projects a difficult task, and hence our focus has tended to be on production or near production assets where we can leverage off our cash position to get to production without the need for further capital raising.
The principal strategy behind the IGO investment was to increase this cash/liquid position to increase our buying power in this market without further dilution to shareholders.
As at 31 December 2008 our total cash, security deposits and liquid assets at cost amounted to $11,306,000.

1. Pilbara Project
The Pilbara Project area lies between 7km and 50km south of Karratha in the northwest of Western Australia, see Figures 1 & 2, and comprises 686km[2] of granted tenements and tenement applications. Legend has previously defined 14 priority drill targets from airborne Versatile Time Domain Electromagnetics (VTEM) and ground EM surveys. The Project is considered prospective for nickel-copper, copper-zinc and iron ore.
Iron Ore Rockchip Sampling
During the Quarter, Legend completed a first pass rockchip sampling programme over the prospective Cleaverville Formation within its Pilbara Project, (see ASX announcement 20[th] November 2008). The Cleaverville Formation hosts the 1.6 billion tonne Cape Lambert Magnetite Project, located 15km to the northeast, which was sold by Cape Lambert Iron Ore Limited (ASX:CFE) in 2008.
A total of 44 rockchip samples of predominantly magnetite bearing banded iron formation (BIF), were collected from over an 18km strike length of Cleaverville Formation, see Figure 3. Of the 18km length sampled, 7.5km is located on 100% owned Legend tenements, with the remaining 10.5km subject to the Mt Marie Joint Venture with Fox Resources Limited (ASX:FXR) in which Legend is earning a 70% interest.
Iron Ore Rockchip Sampling – Legend 100%
A total of 19 BIF rockchip samples were collected from over a 7.5km strike length of Cleaverville Formation located on 100% owned Legend tenements, see Figure 3. Twelve of these samples returned iron values >30% Fe, see Table 1. The BIF has observable outcropping thicknesses of 20-30m within the northeastern 3km of E47/1746, thinning to 10m to the southwest where the proportion of chert increases.
Mt Marie JV (Fox Radio Hill Pty Ltd 100%, Legend earning 70%)
Iron Ore Rockchip Sampling
Twenty five BIF rockchip samples were taken from Mt Marie JV tenements covering a 10.5km strike length of Cleaverville Formation, see Figure 3. Twenty three of these samples returned iron values >30% Fe, see Table 1. Sampling over a 4km zone in E47/1878 returned iron values ranging from 37% to 58% Fe in areas with outcrop widths up to 50m and semi continuous strike lengths of up to 600m. Higher iron values were commonly associated with minor localised hematite-goethite development.

Munni Munni JV (Legend 30%, East Coast Minerals NL 70%)
Planned Geophysical Surveys
Geophysical surveys (Sub-Audio Magnetics; SAM) north, south and west of Legend’s historic Elizabeth Hill Silver Mine have been designed to identify structural targets in the northern part of the Munni Munni JV.
Ground EM is also planned over the western JV tenement targeting Ni-Cu-PGE mineralisation associated with the Cadjerina Dyke, which may represent a “feeder” to the significant Munni Munni intrusion to the immediate south.
Pilbara Project - Next Phases of Work
-
Heritage survey over Osborne and Hickmott prospects.
-
Heritage Agreement negotiations with the Ngarluma Aboriginal Corporation to continue.
-
Drilling of previously identified VTEM/ground EM and iron ore targets will follow all statutory clearances.
-
Geophysical surveys (SAM & EM) over the Munni Munni JV ground is planned.
2. Mt Gibson Project
The Mt Gibson Project is considered prospective for volcanic-hosted massive sulphide (VHMS) style mineralisation similar to Oz Minerals’ world-class Golden Grove Mine situated 100km to the north, Figure 1. Legend, through a study conducted in 2006 by Dr S Carras of Carras Mining Pty Ltd, estimated the residual gold Mineral Resource (Indicated and Inferred) to be 8.7Mt at 1.98g/t gold for 559,000 ounces (see 2006 Legend Annual Report).
Oz Minerals Limited (ASX: OZL) advised Legend during the Quarter of it’s decision not to proceed further with the Mt Gibson JV (see Legend ASX announcement 17[th] November 2008). Oz Minerals met the first phase minimum expenditure requirement of $1.2M through geological/geochemical activities and a diamond drilling programme of approximately 3,000m.
Since the withdrawal of Oz Minerals, Legend has commenced an extensive review of the gold potential of the Mt Gibson Project assessing the structural and lithological controls on gold mineralisation. The review will involve the specialised consulting services of Predictive Discovery Pty Ltd using technology developed at CSIRO in the Predictive Mineral Discovery Co-operative Research Centre. This work will be undertaken in conjunction with a review of the existing resources to target potential new ore positions.

Mt Gibson Project - Next Phases of Work
-
Re-assess the considerable database pertaining to volcanic hosted massive sulphide zinccopper and gold mineralisation at Mt Gibson.
-
Systematic analysis of the structural and lithological controls on the existing gold deposits will also be completed with the aim of identifying additional resources.
-
Review the existing gold resources using current costs and mining parameters.
3. Gum Creek Project
The Gum Creek Project is divided into three areas, Bungarra, Thangoo and Woodley, and is considered prospective for intrusion-related (Ni-Cu-PGE), komatiite flow-related (Ni) sulphide mineralisation and iron ore, see Figures 1 & 4.
Bungarra
Cobra and Sidewinder Prospects
Results were received from five RC drillholes (LCBC001-003, LSWC001-002) completed during the September Quarter. The drillholes were targeting ground EM conductors associated with gabbroic and pyroxenitic lithologies located near the base of the mafic-ultramafic Bungarra Intrusive Complex (BIC).
Drillhole details are provided below in Table 2, while prospect locations are shown in Figure 4.

Two drillholes at Cobra intersected a broad zone (up to 88m in LCBC001) with elevated Ni-Cu-
PGE values, including an interval of 4m @ 0.26% Ni, 0.29% Cu, 105 ppb Pt and 470 ppb Pd from 52m in LCBC001.

At Sidewinder, both drillholes intersected broad zones of low grade zinc mineralisation returning intervals of 48m @ 0.22% Zn from 52m in LSWC001 and 24m @ 0.27% Zn from 56m in LSWC002, associated with a foliated carbonaceous metasediment The two holes also intersected a broad zone with elevated Ni-Cu-PGE in a meta-pyroxenite returning; 24m @ 0.12% Ni, 0.07% Cu and 219 ppb Pt+Pd from 132m in LSWC001 and 36m @ 0.10% Ni, 0.05% Cu and 183 ppb Pt+Pd from 120m in LSWC002. These intersections both included narrow 4m intervals with higher grades of: 4m @ 0.16% Ni, 0.12% Cu and 405 ppb Pt+Pd from 136m and 4m @ 0.17% Ni, 0.10% Cu and 430 ppb Pt+Pd from 140m, respectively.

West Bungarra JV (Legend 70%, Gateway Mining 30%)
Ground EM Survey
A ground MLTEM survey (Moving Loop Time-domain Electromagnetics) was completed in the southern portion of E57/709 over a broad diffuse conductor identified in the March 2008 airborne VTEM survey, see Figure 4. The survey was undertaken in conjunction with joint venture partner Gateway Mining who completed MLTEM on their 100% owned tenement to the immediate south of E57/709.
The survey identified a strong conductor, modelled to be <50m deep with a strike extent of approximately 400m and may represent massive sulphide. Further work is required.
Gum Creek Project - Next Phases of Work
-
Full review/assessment of exploration data over the entire Bungarra Intrusive Complex.
-
Further follow-up of the EM conductor identified on the West Bungarra JV ground.
