Executive Summary
EL 10386 was granted to Kajeena Mining Company Pty Ltd in September of 2008.
Teck Australia Pty Ltd as operator successfully negotiated the grant of the tenement
and exploration Deed with the traditional owners and the Central Land Council.
Desktop targeting for base metals (Broken Hill Type and IOCG systems) identified a
number of discrete areas of interest, however these could not be field tested due to
the outcomes of a cultural heritage survey.

1. Introduction
An agreement with Kajeena Mining was established in 2002 to explore for base
metals (Zn, Cu, Pb) and nickel over a number of tenements including EL 10386.
A Deed with the Central Land Council was executed in 2008 following successful
negotiation with Traditional Owners to explore on the tenement. This
relinquishment report details the desktop mapping completed prior to heritage
exclusion and the subsequent decision relinquish ground.
2. Location
The area of EL 10386 relinquished is located approximately 350km west of Alice
Springs and about 75km south west of the community of Mt Liebig.
Access to the area is from Alice Springs via the Stuart Highway, Tanami Road
and Kintore Road.
The tenement is within the Mount Liebig 1:250K map sheet.
3. Tenure
EL 10386 (182 sub-blocks) was granted to Kajeena Mining on the 2nd of
September 2008. Forty three blocks over six discrete areas of EL 10386 have
been relinquished and are labelled A to F and mapped in Figure 1 and listed in
Appendix 2.
The number of sub-blocks per Area are;
Area A: 3
Area B: 9
Area C: 4
Area D: 4
Area E: 2
Area F: 43

4. Land Access and Heritage Clearances
Negotiations with Traditional Owners to grant the tenement were successful with the tenement granted on the 2nd of September 2008 following execution of an Access Deed with the Central Land Council. Following preparation and submission of a work plan, a heritage survey was coordinated with the assistance of the Central Land Council. The resulting report excluded areas from exploration approximating the relinquished areas A..F. Without the possibility of accessing the areas, the ground was relinquished.
5. Work Completed
a. Literature Review
A literature review confirmed that no previous exploration had occurred on the tenement. A number of publications were sourced and provided useful background for exploration targeting, notably the work by the NTGS (refer Appendix 1). Whilst some NTGS mapping has been completed and interpretive products produced, no systematic field mapping or sampling program has been undertaken.
b. Strategic & Technical Reviews
A number of technical and strategic reviews were conducted during the period involving input from both internal and external specialists.
c. Exploration Targeting
i. Methodology
Exploration targeting involved the integration of expert weighted
layers of geology, structural data, magnetic and spectral
anomalies resulted in the delineation and prioritization of
exploration targets.
ii. Geology
1. Regional
The Warumpi Province is a 1690–1610 Ma accreted terrane, comprising metasedimentary, metavolcanic and metamorphosed plutonic rocks that abut the southern margin of the North Australian Craton (NAC).
2. BHT Target Geology
Target geology comprises metasediments and metavolcanics which may form suitable hosts to Broken Hill Type mineralization. Mapped 250K geology is insufficient to separate various metasedimentary, metavolcanic and meta-intrusive units and without access to the areas no further ground truthing was possible.
Figure 1: Area of EL 10386 and relinquished areas A..F with Proterozoic geology (1Ml) on
topographic background (1ML).
iii. Geophysics
1. Airborne Magnetics
Regional airborne magnetic data at 400m spaced intervals was used to highlight discrete magnetic features with size potential to reflect a Broken Hill Type (Cannington style) or IOCG target.
6
2. Regional Gravity
Regional gravity data was very poorly spaced and not of sufficient quality for the selection of target areas.
Figure 2: Area of EL 10386 and relinquished areas A..F with Proterozoic geology (1Ml) on magnetic (TMI) background.
iv. Spectral Data
1. Landsat data
Was acquired and processed using CSIRO’s Clay (R) – Iron (G) – Silica (B) ratio. Anomalies were identified and used in final targeting as shown in Figure 3.
2. Aster Data
Crosstalk corrected Aster data was acquired and a number of algorithms were applied to map the abundance of hydroxyl minerals, carbonate, silica and iron. Anomalies were identified and used in final targeting as shown in Figure 3.
7
v. Results
Figure 3 shows the results of targeting with numerous areas identified within the exclusion zones.
6. Expenditure
Year 1 Year 2
Desktop Review & Targeting $5317 $2450 Total Expenditure $7767
7. Conclusion
Despite significant efforts and expense to negotiate grant of the tenement and to undertake the technical review and targeting it is disappointing that such large areas were excluded from exploration due to heritage exclusions. Without access to outcrop in such an unexplored terrain technical knowledge has not been advanced.
