Statement to ASX Limited 24 March 2011

With its Mt Forrest Iron exploration progressing well, Mindax is putting in place necessary approvals and aligning infrastructure partners to progress the project.

Coupled with its significant iron assets, Mindax is also the greenfields discoverer of a new uranium province near Mukinbudin, WA.

Through technically advanced exploration and an eye for detail, Mindax has successfully built a significant portfolio of minerals projects in Western Australia's Yilgarn Craton of about 40 tenements covering over 4600 sq km.

Mindax aims to develop strategic resources through innovative exploration. Higher yield projects will be moved to production via Strategic partnerships.

Mt Forrest Iron Project – Interim Drilling Results

Highlights

The last phase of drilling at Mt Forrest is complete with the following positive indications:

  • Six of the 8 magnetite targets drilled and confirm magnetite mineralisation intersections persist at depths greater than 250m below the surface.

  • A significant new category of soft oxidised magnetite material has been identified juxtaposed to defined DSO mineralisation in the thus far uncategorised 0 to 50m zone.

  • Significant coarse secondary high-grade magnetiteepidote mineralisation has been identified at Dingo, Emu and Echidna.

  • Experimental Davis Tube work at Emu and Dingo returns DTC%rec >40%, DTC%Fe >68% and DTC%Si <6% at 80P150 micron grind size.

ASX Code: MDX

  • Revised Resource anticipated at end March

  • Scoping Study on track for end March

In October last year the company released a resource statement that identified 1.01 billion tonnes of beneficiable magnetite ore grading 31 % Fe (JORC Inferred).

In the period since October 2010 to mid February 2011, a further 66 drill holes have been completed at Mt Forrest for an advance of 15,476 metres (including 6 core holes for 820.8 metres of core for metallurgical testing). Further primary assay results not included in the release last January and available Davis Tube test results are included in this announcement.

The data is presented here as raw down hole results. True width intercepts will not be available until resource modelling is complete. The results of metallurgical tests on core are not yet to hand and some Davis Tube results remain outstanding. Outstanding details will be included in an updated resource statement scheduled at end of March.

Total iron focussed drilling at Mt Forrest to date now totals 314 holes completed for an aggregate 29,485.7 m in the fourteen month period since December 2009.

This drilling has the objective of enhancing the existing resource in terms of both quantum and status, of quantifying ore processing characteristics and providing material for further metallurgical testing. This information is important to further quantifying a business case within a Scoping Study and advancing the project to Prefeasibility status.

Mapping and drilling has identified 8 prospects for magnetite ore at Mt Forrest: Kangaroo, Bat, Dingo, Emu, Echidna, Bungarra, Kangaroo, Dunnart and Euro. Six of these (Bat and Kangaroo excluded) have been tested in this drilling program.

Significant observations from this work are:

  • Six of the 8 magnetite targets drilled and confirm magnetite mineralisation intersections persist at depths greater than 250m below the surface.

  • A significant new category of soft oxidised magnetite material has been identified juxtaposed to DSO mineralisation in the thus far uncategorised 0 to 50m zone. This will be included in future calculations subject to suitable beneficiation characteristics.

  • Significant secondary coarse high-grade magnetite-epidote mineralisation has been intersected at Dingo, Emu and Echidna and is interpreted as a primary alteration product and positively influences grade and recovery data where it occurs.

  • Experimental Davis Tube work at Emu and Dingo returns DTC%rec >40%, DTC%Fe >68% and DTC%Si <6% at 80P150 micron grind size. All other test work is carried out at a standard 80P40 micron.

Yours sincerely
