Recent evaluation of the project’s magnetite iron ore
potential has involved aeromagnetic modelling by Southern
Geoscience Consultants (SGC) over 20km of prospective banded
iron formation (BIF) within the Cleaverville Formation.
Results from this work indicate an “Exploration Target” with
the potential for 600Mt to 1,000Mt of magnetite. An expected
grade of 25-35% Fe is considered likely based on reported
grades from the nearby Cape Lambert and Mt Oscar resources,
also hosted by the Cleaverville Formation.
Previous rockchip sampling results (44 samples) over BIF of
the Cleaverville Formation were reported to the ASX on 20
November 2009. This non-systematic sampling programme was
targeting high grade magnetite-bearing BIF, with 30 samples
returning results ranging between 30-58% Fe. Outcropping BIF
units have observable thicknesses up to 50m with semi
continuous strike lengths up to 600m. This confirms the
magnetite potential of the Cleaverville Formation within
Legend’s Pilbara Project. In November 2006, Legend flew an airborne
Versatile Time Domain Electro Magnetic survey (VTEM-1) covering
180km2, The VTEM technique has proven to be an extremely
valuable and cost effective technique in identifying new targets and
known sulphide ore systems in the Pilbara. Priority anomalies
identified in the two VTEM surveys have been followed-up with ground
Fixed-Loop Transient Electromagnetic surveys (FLTEM) defining 14
immediate drill targets. Eleven drill targets fall within Legend’s 100% tenure, two within the Mt Marie JV and one on Munni Munni JV ground. Approximately 50% of the current ground holding has now been flown by the two surveys. Legend is currently negotiating a heritage agreement to gain full access to the project. The commencement of drill testing of electromagnetic targets and further evaluation of the iron ore potential will follow all statutory approvals. IMAGES FROM PILBARA:
