EXPLORATION
MT FORREST PROJECT (Iron, Gold 100%)
Located in the Richardson Ranges Mindax’s (YilgIron Pty Ltd) Mt Forrest Project lies 150 km north-west of Menzies, which is on the railway line to the deepwater iron ore port of Esperance. The project covers seven Mining Leases over 50 sq km.
Systematic detailed mapping and rock chip sampling by YilgIron indicates extensive hematite-goethite-magnetite mineralisation at surface, as multiple bands within a folded greenstone package extending over 17 km of strike.
Mindax has previously announced the status of the iron endowment of the area, most recently in early October of last year. This comprises both revised JORC Resource components for DSO (direct shipping hematite-goethite) and PBM (potentially beneficiable magnetite) materials:

This quarter saw the release of an updated resource statement and a change of focus to the magnetite potential of the Project and recommencement of drilling with the objective of upgrading the currently Inferred PBM resource to Indicated status within the next resource update scheduled at the end of the March (2011) Quarter. Work also started to assess the viability of a magnetite operation and to map what would be required for such a Project Development.
An additional twenty RC holes for 4,539 m (MFC 241 – 258 and 300 – 301) and one diamond hole for 112.2 m have now been completed and the drilling is ongoing. Iron assay results for these holes are included in Tables 1 and 2. These drill results are raw down-hole results and not true width intercepts. Diamond core has not been assayed as it is being retained for metallurgical testwork but is logged and sampled for mineragraphy and petrology.
Three out of the eight PBM targets (Emu, Dingo, Echidna) have had preliminary testing with first pass RC drilling, (Figures 2, 3). The five remaining targets, Bungarra, Euro, Kangaroo, Dunnart and Bat have had limited drilling. Drilling at Mt Forrest to date totals 293 holes completed for an aggregate 19,153.1 m since December 2009.

Systematic DTR data continues to be collected through the resource at 80% passing 40 µm (P80-40). Results for composite samples from Emu indicate generally good mass recoveries and recovered iron grades as well as low silica levels, but material types vary widely. Table 3 shows the DTR results above a 20% DTR cut off.
Tables 1 and 2 are primary assay and collar data. For ease of description and to distinguish PBM and DSO targets that are often closely matched, a new naming convention for PBM targets has been introduced and is shown on the figure below.

Drilling will continue until March 2011 to further upgrade the mineral resource inventory. The proposed drill programs allow for a further 12,000 m of RC drilling and 2,500 m of diamond core drilling.
The study scoping out all of the aspects that will need to be addressed moving forward towards a Decision to Mine and a Mining Permit is well advanced. Our short term objective is to move into a Prefeasibility Study based on an upgraded resource model derived from the current drilling program. Our present plan is to present a PFS towards the end of this financial year. In the longer term if the project successfully completes definitive feasibility, we would see a decision to mine late in 2012 and production late in 2015.
During the Quarter a program of metallurgical testing and plant design commenced. Application for a corridor from Mt Forrest to the Menzies railhead to secure a road haulage power and pipeline route was made and 2D/3D studies to support these activities and to plan a possible rail route were initiated. Water studies were initiated. Discussions with rail and port people as well as involved government agencies commenced and a program of marketing directly into Asia commenced in November.
Competent Person
The mineral resource estimates (“the estimates”) are reported under the Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code, 2004 Edition). The estimates were carried out by Mr Chris Allen, BSc (Hons), MBA, MAIG of CSA Global Ltd who is a Member of the Australian Institute of Geoscientists (MAIG), and who has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined by the Code.
Mr Allen consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
The Yilgarn Iron Producers Association (YIPA) was initiated early in October with Mindax Ltd/YilgIron Pty Ltd as a founding member. YIPA will focus on issues of common interest with miners and other explorers in the Yilgarn area, with a particular interest in infrastructure issues through to Esperance.

YILGARN AVON JOINT VENTURE – URANIUM PROJECT (53% and operator)
Mindax (Mindax Energy Pty Ltd) in joint venture with Quasar Resources, the Yilgarn Avon Joint Venture (YAJV), is searching for roll front uranium in palaeochannels of South-Western WA. The Yilgarn Avon project has already demonstrated very significant uranium anomalism in ground waters to >1,000 ppb uranium and suitable carbon traps for uranium within the drainages in this hitherto unexplored region.
A scout drilling campaign of widely spaced holes to basement is ongoing, aimed at determining the general geological morphology of the Yilgarn palaeochannel and its geological and hydro-geochemical characteristics, particularly with respect to uranium mineralisation.
At Mukinbudin, 200 km north-east of Perth, the program has demonstrated sedimentary style uranium mineralisation to 0.2% U3O8 at the Jindarra prospect covering in excess of 2 km of the palaeochannel. A second target area is now indicated at Yandegin , 30 km down stream of Jindarra.

Mukinbudin Project
Scout Drilling - Yandegin Prospect
Two further phases of scout drilling have been conducted at the Mukinbudin Project during late August and October. In total 37 holes were completed for 3,093 m.
Scout drilling was conducted along five new traverses to begin to ensure a more consistent line spacing of approximately 5 km spaced traverses along the channel. The primary aim of the scout drilling program is to determine channel morphology. Six drillholes returned anomalous uranium values of greater than 100 ppm. These results are listed in Table 4 below.
| Hole ID/EOH | Depth | Interval (U ppm) | Interval (U3O8 %) |
|---|---|---|---|
| YAA0267 – 59 m | 41 - 43 m | 2m @ 119 ppm | 0.014% |
| YAA0269 – 56 m | 29 - 30 m | 1m @5368ppm | 0.633% |
| YAA0269 | 40 - 46 m | 6m @ 141 ppm | 0.017% |
| YAA0270 – 44 m | 33 - 37 m | 4m @ 620 ppm | 0.073% |

The two stand out drillholes in this phase of drilling are YAA0269 and YAA0270.
These holes are adjacent and 150 m apart on the same traverse. Drillhole YAA0269 encountered 1 m @ 5,368 ppm U (0.63% U3O8) at 29 metres . YAA0270 was drilled south of YAA0269 and encountered 4 m @ 620 ppm which included 1 m @ 2,000 ppm (0.24% U3O8) at a depth of 34 m . This new area of mineralisation is called the Yandegin prospect and is located 25 km downstream from the Jindarra prospect.
Drillhole YAA0149 drilled in 2009 encountered 1m @ 308 ppm U and is located 1 km downstream (southwest). The next drill line upstream (north east) is 9 km away and returned a value of 1 m @ 292 ppm U (YAA0154).
The results to date from Yandegin are the best so far encountered in the Wheatbelt and are significantly greater than the previously announced high grade material at nearby Jindarra (0.2% U3O8).
Mineralisation in both YAA0269 and YAA0270 is associated with carbonaceous, reduced sand layers which are bounded by oxidised sandy clays. The change in redox conditions between the sand and clays is the catalyst for the precipitation of uranium mineralisation with the highest grades being located at the unit contacts themselves. YAA0269 contains two units of mineralised sands, a high grade upper layer with a very well mineralised upper contact and then at 10 m deeper a moderate grade layer, while YAA0270 is located in a shallower part of the channel and only contains a single high grade layer also with a very well mineralised upper contact.
The peak uranium number in YAA0269 is associated with elevated values in other elements . Table 5 shows these results. All values are in ppm.
| Hole ID | Depth | U | Ag | Co | Cu | Mo | Ni | Pb | Th |
|---|---|---|---|---|---|---|---|---|---|
| YAA0269 | 29 - 30 | 5368 | 4.09 | 60 | 358.3 | 34.3 | 101 | 5537.9 | 534.62 |
Table 5: Multi-element results in ppm.
These results provide further encouragement in the exploration model and that the Wheatbelt of WA has the potential to host an economic uranium resource.
Diamond Drilling
Three diamond drillholes were completed during the quarter for a total of 323.4 m. Two holes were drilled at the Jindarra prospect and a third hole further downstream in an area where anomalous uranium values had been intersected in the scout drilling (YAA0149, 1 m @ 308 ppm U). These diamond drillholes were drilled to collect valuable stratigraphic information. The core generated will allow better interpretation of the sedimentary environment of the palaeochannel. These holes were sited near aircore holes that had encountered uranium mineralisation and will provide further insight to the detailed setting of mineralisation.

Gravity Surveying
A large program of ground gravity surveying is underway. Approximately 4,500 stations of a planned 7,000 station program have been completed. The remaining stations, along with any infill required will be completed in January and February 2011. Surveying has been conducted at the Mukinbudin, Quairading and Kellerberrin Projects. The gravity data will be used to help interpret the morphology of the palaeochannel to allow better targeting of the scout aircore drilling.

YILGARN AVON JOINT VENTURE - MORTLOCK PROJECT (Copper, Gold, Uranium, 53% and operator)
The Yilgarn Avon Joint Venture (YAJV) at the Mortlock Project controls 1,070 km[2] , covering the Centre Forest and Southern Brook gold-copper prospects (CFSB Trend) in the Goomalling area, 100 km north-east of Perth. The regional geology comprises of high-grade metamorphic rocks extending south from the Wongan Hills greenstone belt. Two potentially mineralised belts are recognised within the area with one passing through Centre Forest, the CFSB trend and the other through Jennacubine parallel and 5 km further to the west.
Wide intercepts of low grade copper-gold mineralisation have been drilled by previous explorers on the CFSB Trend. A composite of drilling and surface geochemistry indicate a zone of copper anomalism of some 6 km length between Centre Forest and Southern Brook. Airborne EM geophysics shows conductivity anomalies coincident with this geochemical corridor. The target CFSB zone is open along strike in both directions with a regional geophysical and geochemical signature extending potentially over 20 km. The Jennacubbine Trend persists over a similar distance also as a zone of geophysical and geochemical anomalism but remains undrilled.
The YAJV Mortlock project includes the right to earn 80% in certain adjacent tenements held by Sipa Resources, which partly cover the target horizons. A potential iron target has been identified to the east at Wilding Road.
Ground Electromagnetic Survey
A fixed loop ground electromagnetic survey was conducted over two areas of interest. Airborne EM targets VC-4a, VC4b & VC-5 (Centre Forest East) and VC24 & VC-26 (targets south west of Southern Brook) were tested. Interpretation and modelling of this data by Mindax’s consultant geophysicists suggest that there are conductive responses representing drill targets at Centre Forest East (VC-4a, VC4b & VC-5) but not at the area of interest to the south west of Southern Brook (VC24 & VC-26).
The conductive bodies lie immediately to the east of the Centre Forest Cu-Au mineralisation, within the interpreted hanging wall stratigraphy. The Centre Forest mineralisation consists of wide intercepts of copper-gold mineralisation but it has no distinct airborne conductivity signature.
Earlier broad spaced air core drilling across the AEM targets at Centre Forrest East has identified significant blankets of anomalous copper geochemistry (>1000 ppm Cu) within regolith overlying basement. The conductive bedrock responses identified by the ground EM lie beneath this anomalous copper blanket.
A program of three RC drill holes totalling 760 m have been designed to target these conductive bodies and drilling is in progress, All necessary approvals are in place. Four further areas of interest (priority AEM targets) that were not available for surveying, due to cropping activities, will be surveyed in January 2011.

OTHER PROJECTS
BULGA DOWNS WIDE PROJECT (Iron, Gold, 100%)
The Bulga Downs Wide Project includes those tenements adjacent to the Mt Forrest mining leases where there is prospectivity for gold and also for iron that would be of strategic relevance to any mining operation at Mt Forrest. They include the Panther and Tiger iron prospects where surface sampling has returned >60% Fe and overlapping areas of gold-insoil geochemistry. The areas to the north of Mt Forrest in and beyond Maynard Hills include targets unresolved by drilling where there is some potential for gold.
The Tocatta gold anomaly (E57/598 and E57/788) was drilled during September. Forty five holes were drilled for a total of 2,475 m. All assays were received during the quarter. No significant gold assays were reported from the program. As a consequence these tenements were relinquished during the quarter.
A reassessment of the iron potential of E29/533, E29/534, E57/555 and E57/787 concluded that there is likely no opportunity for the discovery of a significant iron resource, the tenements were therefore surrendered.

MEEKATHARRA NORTH PROJECT (Gold, 100%)
The Meekatharra North Project lies 20 km along structure from the Paddy’s Flat field (where 2.5 million ounces of gold have been produced) and immediately south of the emerging Andy Well prospect on the same regional structure. The area is substantially covered by a thin blanket of colluvium and deeper palaeochannels. Drilling has identified a series of blind mineralised and altered shears through the area.
No work was undertaken during the quarter.
