Executive Summary

1. The program objective is to provide high resolution airborne magnetic and radiometric data over the Calvert Fracture System for interpretation by Southern Geoscience Consultants, using 200m line spacing, supplemented by data from 100m spaced lines to be acquired concurrently by Redbank Copper Limited.

2. The current airborne magnetic and radiometric data package relies on 400m spaced lines of earlier vintage. Compared to the proposed 2011 data acquisition methods and technology it is considered too low quality for detailed mapping and structural interpretation purposes.

3. Southern Geoscience Consultants have completed an initial interpretation of the existing information, and have recommended that acquisition of more detailed magnetic and radiometric data is actioned as the precursor for the Company’s expansion of its proposed three year regional exploration program.

4. Stream sediment geochemistry (Pre 2010), coupled with Redbanks reconnaissance stream program in 2010, and a laterite sampling program on tenement adjacent to the Calvert Fracture Zone demonstrates anomalous responses in Cu, Pb, Zn, Au, Ag, Tl, Co and REE’s.

5. The airborne magnetic and radiometric survey flown August 6-16th 2011, used 200m line spacing. Due to corporate and budget constraints, the infil survey to be flown at 100m line spacing was deferred until 2012.

6. Although the geophysical data has not been interpreted, it does suggest a number of magnetic anomalies within EL27241, EL26778, EL26779 and EL27329 require further detailed investigations, as these coincide with a number of geochemical anomalies from the 2010 sampling programme.

Introduction The Project area is located on the Calvert Hills 1:250,000 sheet. Figure 1 shows the location in both a regional and detailed context. The proposed location for the geophysical survey is contained within the Company’s “Calvert Project Area”. Access is via the Savannah Way and Calvert Road, both annually maintained public gravel roads, and then via station tracks on both Calvert Hills and Wollogorang stations. The Company has extremely good working relationships’ with the owners and management of both stations having undertaken previous exploration and mining activities within their boundaries. Arrangements for the 2011 exploration activities included airborne geophysical, helicopter supported stream, soil and rock sampling programs and drilling have been discussed and finalized whereby Redbank will continue to hire equipment providing income and closely liaise with the 2011 mustering program to avoid any disruption.

Figure 1. Location Plan Regional Geology The McArthur Basin is an extensive and complex Palaeo- to Mesoproterozoic sedimentary basin that forms the western extension of the Carpentaria Zinc Belt, which includes the Mount Isa region. The basin unconformably overlies the Palaeoproterozoic Pine Creek Orogen to the northwest, Murphy Inlier to the southeast and Arnhem Inlier to the northeast. It is unconformably overlain by the Arafura, Georgina and Carpentaria Basins (Figure 2).

Figure 2. Tectonic framework of the McArthur Basin (Northern Territory Geological Survey, 2001)

The McArthur Basin contains a mixed carbonate and clastic depositional succession. The basin is a broad, shallow, crustal depression bisected by a much deeper structure known as the Batten Trough. This trough is flanked by the Bauhinia Shelf to the west and the Wearyan Shelf to the east (Figure 4.1), the latter hosting Redbank's project area. The Wearyan Shelf, in particular the Tawallah Group, contains all of the volcanic rocks in the McArthur Basin. The McArthur Basin hosts the McArthur River lead-zinc-silver mine and diamond-bearing kimberlites (i.e., Merlin). Additionally, the basin contains numerous significant base metal occurrences (i.e., Redbank), along with diamonds and minor uranium mineralisation within the basal units (i.e., Westmoreland Conglomerate). In the Redbank area, the Neoproterozoic to Palaeozoic intracratonic Georgina Basin sequence unconformably overlies the Murphy Inlier and the McArthur Basin. The Georgina Basin contains a suite of clastic and chemical sediments including dolostone, limestone, shale, sandstone, and siltstone and is in turn unconformably overlain by the Mesozoic Carpentaria Basin. The Georgina Basin is a major exploration target for sedimentary phosphate and contains several occurrences and deposits, e.g., Wonarah phosphate deposit. Additionally, the basin is explored for manganese, base metals, oil and gas. The overlying Carpentaria Basin also contains a sequence of clastic and chemical sediments. This basin hosts numerous additional bauxite and manganese occurrences. Local Geology Redbank's landholdings occur to either side of the NW-SE trending Calvert Fault zone, the main structural feature on the Wearyan Shelf (Figure 4.1). The tenements may be divided into three main groups based on lithostratigraphy and associated mineralisation styles as well as their vicinity to the Calvert Fault zone, namely Copperado, Calvert Area and the Southeast Area. The McArthur Basin sequence dips on a regional scale to the north-northwest at a very low angle. On a local scale the rocks are folded into shallow domes and troughs, with some small-scale block faulting. As a result of the gentle northwesterly dip the oldest units, including the lower Tawallah Group (i.e., Westmoreland

Conglomerate, Seigal Volcanics, McDermott Formation), are mainly exposed across Redbank's southern exploration leases in the vicinity of the Murphy Inlier. Further to the north and northwest the lower Tawallah Group is overlain by the Sly Creek Sandstone, Aquarium Formation, Settlement Volcanics, Wollogorang Formation, Golden Creek Volcanics and the Hobblechain Rhyolite, all of which form the upper Tallawah Group (Figure 3 and Table 1).

Figure 3. Regional geological map of the tenement area, illustrating the occurrence of favourable lithologies The Tawallah Group is in turn unconformably overlain by the Masterton Sandstone, which represents the basal unit of the McArthur Group. Extensive outcrops of Masterton Sandstone are found immediately to the north of the Calvert Fault zone. The Masterton Sandstone is unconformably overlain by the Karns Dolomite, which represents the Nathan Group in Redbank's project area.

Calvert Project Geology The Calvert Project Area combines the tenements which are located in the immediate vicinity of the Calvert Fault zone (Figures 1&3). Bedrock outcrop is dominated by McArthur Basin sediments and volcanics to the north of the Calvert Fault zone. The Settlement Creek Volcanics, as well as dolomitic sediments of the Wollogorang Formation, occur in the immediate vicinity of the fault. Further to the north these rocks, which are part of the lower Tawallah Group, are overlain by Masterton Sandstone and Karns Dolomite.

Palaeozoic and Mesozoic sediments of both the Carpentaria and Georgina basins are widely exposed south of the Calvert Fault zone. The 'blanket' of these sediments (i.e., Bukalara Sandstone, Mullaman Beds) is disrupted by several anticlines composed of the Proterozoic McDermott Formation. Previous Exploration Copper was first reported from the Settlement Creek area near Wollogorang in 1899. Masterton discovered copper at Redbank, 20 km west-northwest of Wollogorang, and subsequently a number of other deposits in this area. Lead in the Gorge Creek area near the Fish River fault zone was probably discovered by the turn of the century. Uranium was discovered at the Eva mine and Cobar II in 1956. The discovery of tin at Crystal Hill, just to the south of the tenement area, was probably made at about the same time. Since these early discoveries three periods of extensive exploration are recognized. From around 1956 to 1960 most exploration was directed towards locating uranium deposits. Between 1968 and 1971, there was extensive exploration for copper especially in the Redbank area. The diamond search became important after 1978 and the Merlin Diamond Field was discovered in 1987 and the Coanjula diamond prospect about the same time. In all there are 360 relevant reports on open file dating from 1956. In 1974 to 1977, Triako Mines NL assessed the Redbank deposits and surrounding ground. Exploration resulted in the recognition of 26 circular structures worthy of investigation for breccia pipes. The Buffalo Fly Prospect about 7 km north-west of Redbank is a broad topographic depression about 1200 m across within the Masterton Formation with anomalous surface base-metal geochemical values. A diamond drill hole drilled circa1980, by Amdex Mining Limited was stopped at 72 m in a siltstone containing occasional chalcopyrite; the best copper assay result was 15 m grading 707 ppm copper. Other explorers for base-metals were Amax Exploration (Australia) Pty Ltd, 1978; Hunter Resources Limited, 1986; Restech Australia Ltd, 1988 to 1989; Ashton Mining Limited, 1993 to 1996; Mount Isa Mines Limited, 1995; BHP Minerals Pty Ltd, 1996 to 1997 and Rio Tinto Exploration Pty Limited-formerly CRA Exploration Pty Limited (“CRAE”). During the period 1990 to 1998, CRAE under Exploration Licences 7101, 7102, 7175, 7187 and 7934, explored the area for stratabound and skarn hosted base metal deposits and diamonds. Exploration activities and results are detailed in twenty-one Annual Reports. The CRAE investigations are entirely relevant and the results support the exploration initiatives of Redbank Copper. Stream sediment geochemical data has been retrieved from the NTGS and results relevant to Redbank’s tenement package assessed. The data were normalized to remove artifacts attributed to batch, method and laboratory influences. The normalized data specifically for the Calvert Project Area are shown in Appendix 1 as “Anomaly to Background” or Response Ratios (RR) values. Reconnaissance stream sampling during 2010 identified copper/ gold/thallium and lead/zinc/silver responses within the Calvert Project and laterite sampling on the adjacent Benmarra Project identified discrete Cu, Pb, Zn, Ag, As, Ni, Co, and REE’s anomalous trends indicative of chalcophile corridors. It is thought that these may represent “splay structures” originating from the Calvert Fracture Zone. Previous airborne geophysical surveys flown at 400mx400m line spacing are shown in Figure 4. Interpretation of this data by Southern Geophysical Consultants (SGC), commissioned by Redbank during 2010-11, is shown in Appendix 2 as interpretive plans. A summary report from SGC regarding the suitability of the existing magnetic and radiometric data, and the benefits/reccomendation of acquisition of higher resolution data, is also provided in Appendix 2.

Mineralization Styles and Exploration Concepts A number of metallogenic zones are recognized across Redbank's land holdings within the southern part of the McArthur Basin. These zones are characterized by different ore parageneses, mineralization styles, and host lithologies, which are summarized in Table 2. The company believes that its tenements are favorable for the location of world-class deposits on the basis of the geological environment, geophysical and geochemical anomalism and structure. Conceptual models for base metal mineralization are very large size, low grade stratabound copper (and cobalt) mineralization in the lower and upper units of the Wollogorang and McDermott Formations and large and medium grade zinc-lead-silver stratabound mineralization in the middle units of the Wollogorang Formation (similar to McArthur River and Century Deposits). The copper anomalism currently identified could lead to mineralization of the diverse copper-belt style. Large zinc-lead-silver targets are also valid and significant concentrations of these metals are invariably located near growth faults, within the thicker parts of the sedimentary basin, from which the metals are derived. The interpretation of previous exploration data has identified anomalous levels of copper, gold, lead, zinc and silver mineralization within the Calvert Project Area. Proposed Program Project Objective. The program objective is to provide high resolution airborne magnetic and radiometric data over the Calvert Fracture System for interpretation by Southern Geoscience Consultants, using 200m line spacing, supplemented by data from 100m spaced lines to be acquired concurrently by Redbank Copper Limited. Project Rationale Magnetic and Radiometric Data The current data base has been compiled from public domain data sets; i.e. NTGS / GA surveys of various vintages and open file survey data retrieved from the NTGS company reporting system. Most of these data sets are reasonable quality. Their main limitation is the wide line spacing of the original surveys, typically 400-500m, with occasional more detailed surveys. For the magnetics, data of this quality and resolution is suitable for regional and early project scale interpretations, at typical effective interpretation scales of 1:250,000, 1:100,000 and 1:50000 scales. At more detailed scales, such as the 1:25000 scale being used for Redbank’s Calvert Fault interpretation, the low resolution of the data makes definition and correlation of magnetic units difficult and often equivocal. As a result, the quality and reliability of the interpretation is significantly compromised as a tool for prospect identification and targeting. Because of the point source nature of radiometric responses, the existing wide line spaced data is of quite limited value for identifying specific radiometric anomalies that could be indicative of outcropping uranium mineralization, which, considering previous exploration activities in the region, are likely to have small areal extent and quite subtle responses. Magnetic/Radiometric Interpretation The interpretation completed to date indicates a more complicated stratigraphic and structural scenario than is shown by the published geological mapping. The north westerly trending Calvert Fault does not appear to be as well defined in the magnetics as indicated by the mapping.

It often presents as a complex and somewhat diffuse zone rather than well defined, relatively simple fault system. Higher resolution magnetics would help improve the definition and understanding of this important structural zone and similar, sub-parallel structures evident in the existing data. Another strong fault / fold set has also been interpreted in the prospective stratigraphy. This generally east-westerly structural set may be reflecting the dominant trends apparent in the older basement rocks the Murphy Inlier and also appears to be a control or influence during deposition of the prospective stratigraphy. The interaction and timing relationships between this structural set and the Calvert Fault set is complicated and unclear. Higher resolution data would again help improve our understanding of these structures and help with targeting favorable loci for fault controlled alteration / mineralization. Higher resolution data should also help elucidate some of the ambiguities currently present in the stratigraphic correlations incorporated in the interpretations. Data Acquisition Data was collected by Thomson Aviation under the direction of Mr Roger Henderson a qualified and highly experienced Geophysicist. The survey used a PAC 750 aircraft providing slow low-level flight characteristics operating a Geometrics G823-A Caesium Vapour Magnetometer which provides high resolution and fast cycle times, both key to accurately measuring the total magnetic field of the earth. The acquisition system samples the magnetometer at 20 readings /sec equating to an average magnetic sample distance of <4 meters - 50% better than industry standard. Radiometrics acquisition employed an advanced airborne spectrometer- the Radiation Solutions RS-500. This system consists of 33 litres of NaI crystal and with new digital signal processing techniques, the spectrometer has an effective dead time of zero seconds. This results in an increase in counts of 25 to 30% in comparison with other existing airborne spectrometers in the market. Half second sampling of the spectrometer is standard, providing a sample interval of less than 40 metres with no loss of spectral resolution and much increased spatial resolution. Thomson Aviation pilots typically fly agricultural operations requiring much higher accuracy than geophysical surveying. Typically a proposed terrain clearance of 30 meters is flown pending any issues arising from the initial inspection, e.g. tall trees, communication towers, etc. Data was processed by Thomson Aviation at an in-house data processing centre utilizing both Intrepid and Geosoft software for data Quality Control and final processing. Magnetic data was processed using Intrepid leveling to produce high quality final products to an image processing standard. Radiometric data was processed using modern full spectrum processing techniques incorporating NASVD and MNF noise reduction.

Thomson Aviation is a full member of the International Airborne Geophysics Safety Association (IAGSA) and adheres strictly to a Safety Management System.

Survey Area The total survey area is shown in Figure 4. Redbank as part of its planned Calvert exploration program flew 8750 line km of survey at 200m line spacing. It has an arrangement with other exploration companies to share the cost of mobilization/demobilization of the Thomson system. The first phase of the survey was flown as: Phase 1. Line spacing of 200m Area 1614 km2 Total line km 8750km

Phase 2 will be flown during the 2012 field season, and be used to acquire data over areas identified as significant and warranting higher density acquisition. The Redbank survey over the Calvert Fracture system cost $169,006 (ex GST). This excludes the second phase infill at 100m line spacing. Conclusion: The results of the 2010 regional stream geochemical sampling programme (Appendix 2) has highlighted a number of catchments within ELs 26779, 27241 and 27329 which warrant further investigation with the recent airborne geophysical survey over the Calvert fracture System. The deferred infill airborne magnetic and radiometric survey at 100m line spacing during 2012 is expected to generate more specific targets for future drill programmes within these tenements.
