        Vale Form 20-F Dec 2011                                             

Minemakers aims to take advantage of Wonarah's favourable infrastructure position and political stability to develop a major centre for the production of beneficiated rock and downstream phosphatic fertilisers and/or intermediate products. Wonarah's advantages, apart from its size and grade, include:

--  Bitumen highway access. 
--  Proximity to a standard gauge railway with spare freight capacity. 
--  Proximity to a natural gas supply, the pipeline for which closely
    follows the railway line. 
--  Access to an established bulk commodity port at Darwin. 
--  Situated in a stable political jurisdiction. 
--  Situated on land owned by the Traditional Owners, with whom a life of
    mine Mining Agreement has been signed which covers mining, processing
    and fertiliser production. 
--  Proximity to ample groundwater. 
--  Proximity to a regional population centre at Tennant Creek. 


A Bankable Feasibility Study ("BFS") is underway, which considers two technical options for Wonarah's development; the traditional wet acid process ("WAP") and the IHP kiln based patented technology ("IHP"), owned by JDCPhosphate Inc. ("JDCP") of Florida. The study represents an extension of the work that was undertaken for the Direct Shipping Ore ("DSO") feasibility study in 2010.

The BFS will update, extend and/or validate the earlier studies and initiate new studies for aspects of the project that were not required in earlier evaluations, such as tailings storage. Investigations will cover the full range required for preparation of a BFS, the major elements of which will include:

--  Approvals 
--  Environmental and Social 
--  Geology and Resources 
--  Mining and Reserves 
--  Beneficiation 
--  IHP 
--  Tailings Storage Facility 
--  Project Logistics 
--  Surface Hydrology 
--  Hydrogeology, Water Supply and Water Balance 
--  Marketing 
--  Financial Analysis 

A technical decision on the development route for the project will be taken 
in mid-2013.                                                                
1. Wet Acid Process                                                         
The production of high-analysis granular phosphate fertilisers, such as DAP 
and MAP, near the township and regional centre of Tennant Creek, which      
provides natural gas, rail and highway connections, and its social          
infrastructure. The process entails:                                        

--  Mining 
--  Beneficiation to 30% P2O5 on site 
--  Slurry pipeline transport of beneficiated rock to Tennant Creek 
--  Reaction with sulphuric acid to produce phosacid 
--  Filtration to remove gypsum 
--  Concentration of acid through condenser to MGA (54% P2O5) 
--  Ammoniation of phosacid and granulation, introduced to produce DAP/MAP -
    high nutrient value products 

2. Improved Hard Process                                                    
The production of high-value superphosphoric acid ("SPA") on site utilising 
the IHP. Minemakers owns 3.2% (post recent dilution) of JDCP, and additional
news on JDCP is presented below under the header, "JDCPhosphate Inc. -      
Florida Demonstration Plant". Through its investment in JDCP, Minemakers has
exclusive rights to the IHP in Australia until 2019. The IHP entails:       

--  Mining 
--  Beneficiation to 15-20% P2O5 
--  Grinding with petroleum coke and silica 
--  Pelletisation 
--  Roasting in a ported rotary kiln 
--  Delivery of a phosphorus rich gas 
--  Hydration process 
--  Superphosphoric acid production at a contained 70% P2O5 - a very high
    nutrient product 

Both alternatives will likely require some beneficiation of the mined phosphate rock. Diamond drilling to obtain samples for testwork was completed during the June 2012 Quarter, and samples were freighted to Adelaide where they have been crushed, assayed and composited in preparation for various tests.

The testwork programme relating to the IHP has been largely completed with testwork results indicating that a satisfactory feed product for the IHP plant can be produced using simple crushing and attrition, which removes unwanted clays from the ore.

Confirmatory testing using the optimised conditions will be undertaken early in the March 2013 Quarter together with screening testwork on the silica sand which overlies the deposit and which will be required as one of the inputs into the IHP feed.

It is anticipated that all testwork in relation to the IHP will be complete early in the March 2013 Quarter.


Previous resource estimates released in November 2011 resulted from exploration targeting higher grade areas suitable for DSO phosphate rock production. Delineation of high grade bodies requires relatively close spaced drilling for resource estimation at even the Indicated confidence level.

As the development plan for Wonarah is now for a larger downstream fertiliser operation rather than a DSO operation, Minemakers has recently been focussed upon broader areas of mineralisation, which could be mined at a lower grade as this will be feed to a beneficiation plant. Additionally, should the IHP be adopted, a lower P2O5 ore grade with a higher silica content will be required.

Minemakers' independent geostatistical consultants, MPR Geological Consultants Pty Ltd ("MPR"), were requested to analyse Minemakers' extensive drill data base to re-estimate resources, based on the requirement to feed a beneficiation plant.

The new resource estimates, at a 10% cut-off are as follows:

              Measured    Indicated    Measured + Indicated      Inferred   
              Mt   P2O5%    Mt  P2O5%             Mt    P2O5%      Mt  P2O5%
Arruwurra   25.7    18.7  27.7   17.8           53.4     18.2      82     16
Main Zone   52.6    21.8   194   17.4            247     18.3     460     18
Total       78.3    20.8   222   17.5            300     18.3     542     18

The Measured and Indicated Resource categories can be used in due course as the basis for determination of Proven and Probable Reserve estimates as part of the ongoing BFS.

Although it is not certain that future drilling will be successful, infill drilling has the potential to convert a significant portion of the Inferred Resources to higher confidence categories.

As feed to an IHP kiln is likely to be at a lesser grade, resources combined for the two deposits estimated at a 5% cut-off are as follows, and they indicate the very large size of the Wonarah deposit:

    Measured     Indicated     Measured + Indicated                Inferred 
   Mt     P2O5%  Mt   P2O5%           Mt          P2O5%        Mt      P2O5%
 82.3      20.2 391    13.2          473           14.4       933         13

The extent to which mining, metallurgical, infrastructure, permitting, marketing and other financial factors may affect the Mineral Resource Estimates has not yet been established. Mineral Resources that are not Mineral Reserves do not have demonstrated economic validity.

The following table compares the 2012 estimated resources to the previous 2010 estimate. As that latter estimate did not include Measured Resources, the 2012 Measured and Indicated categories were combined for comparative purposes.

The 2012 Inferred estimates represent an increase in estimated resource tonnages of 16% for Main Zone, and 13% for the combined project.

MPR estimated that, in addition to the Mineral Resources described above, broadly spaced drill holes at Main Zone suggest the presence of further mineralisation with exploration potential of approximately 150Mt to 250Mt at an average P2O5 grade of approximately 15% to 20%. This potential mineralisation is based on broadly spaced drilling and has had insufficient exploration to define a Mineral Resource, and the estimates of tonnage are conceptual in nature. It is uncertain that further drilling will convert any of the exploration potential to a Mineral Resource.

An RC drilling programme commenced on 8 September 2012 drilling through to 24 September 2012 when crew break and rig maintenance interrupted the programme. The programme was completed in early October 2012. This programme was targeting high grade and relatively shallow phosphate intersections to the north of Main Zone and close to the Barkly Highway, as well as broadly spaced testing to the northwest of Main Zone and in the western target area to determine their overall prospectivity and to confirm areas that need to be retained for potential future production. A total of 2,945m was drilled during the Quarter.


On 20 December 2012, the Company's environmental consultants, Coffey Environments, submitted on behalf of Minemakers, a new Notice of Intent to the Northern Territory government, thereby triggering the Territory's environmental assessment process.

The submission of the NOI was preceded by a company briefing session with the various government agencies involved in the assessment process.

The Company expects to be advised of the level of assessment required and will be issued with a set of guidelines during the first Quarter of 2013. It should be noted that the NOI, and subsequent assessment document, will be restricted to addressing the differences between the previously approved DSO project and the project now proposed. This will significantly reduce the time and cost of the environmental part of the BFS.


Minemakers continues to engage actively with potential project partners for the Wonarah project. The key criteria remain technical input, support in financing and off-take of product.

Our increasing understanding of the IHP, especially as it relates to timing and extent of capital expenditure coupled with the cash received from the sale of our Namibian assets, allows us more flexibility as it relates to partner selection. It is possible, should the IHP technology be selected as the preferred technical route, that Minemakers proceeds to the first 200,000tpa module without a partner or with a minority equity off-take partner, albeit our preference remains to secure a JV partner at this stage.

As a consequence of the above, we are able to be more selective in our partner choice and ensure that the ensuing business combination is sustainable and value enhancing.


Minemakers owns 3.2% of JDCP which in turn owns the patented process to produce SPA by the IHP.

JDCP successfully concluded the first tranche of funding for its demonstration plant in late 2011 and in August 2012 announced that a second tranche had been concluded. Notable amongst the investors in the second tranche were Mitsui & Co (USA) Inc. and Vulcan Phosphates LLC (a special purpose entity formed by the owners of Agrifos Fertilisers LLC). The participation of these two companies provides strong encouragement as to the prospects of commercialising this technology.

In the March 2012 Quarter, JDCP commenced construction of a demonstration plant at its site in Fort Meade, Florida. Commissioning is anticipated in the first half of 2013. The plant will have a capacity of 12,000tpa of high quality and high concentration SPA.

It is expected that each commercial IHP production train will produce 200,000t of contained P2O5. Were Wonarah to be developed using the IHP it would enable the option of a staged approach to be taken, which would minimise the initial capital outlay to enter production and spread total capital expenditure over several years.

To view "Figure 4: JDCP Demonstration Plant under construction, ported kiln now in place, January 2013", please visit the following link:

Construction of the JDCP IHP demonstration plant is nearing completion at Fort Meade in Florida. As of 25 January 2013, it was approximately 90% complete with on-site assembly of the kiln in progress together with electrical and instrumentation cabling and piping being run. Operational personnel are being recruited and include a number who have undergone specialised training at a local college. They will take up their roles progressively over the next few weeks in order to familiarise themselves with the plant prior to start-up.

Members of Minemakers management team visited the Fort Meade site in January 2013 to coordinate JDCP's technical support for Minemakers BFS to ensure complete integration of the IHP into the overall study. The JDCP study team will comprise members of the engineering team who have just designed and built the demonstration plant. Our project will benefit enormously from the insights that they gained during that process.


In December 2012 Minemakers announced it had completed the sale of its 42.5% interest in the Sandpiper Phosphate Project and 70% interest in the Rocky Point Project in Namibia to Mawarid Mining LLC for approximately A$25 million. Cash payment was received on 12 December 2012.

The sale was conditional upon Minemakers shareholder approval and upon Namibia Competition Commission approval, both of which were obtained during the Quarter.

Minemakers will not have cash tax payable on the proceeds from the sale due to existing group tax losses.

As a condition of the sale Minemakers has agreed to not engage in any activities that compete directly with the Sandpiper Project in Namibia for a period of five years except as it relates to JDCP or its dry kiln technology.

Completion of the sale of the Company's Namibian phosphate assets signifies the end of various unsuccessful attempts to consolidate the ownership of the Sandpiper Project. Realising an attractive and certain cash value for those assets in the current economic climate provides Minemakers with significant flexibility in pursuing the development of Wonarah, including partner selection, as well as the opportunity to pursue other growth initiatives.

Minemakers retains an indirect interest in the Sandpiper Project through its 13.81% shareholding in UCL Resources Limited providing Minemakers shareholders with exposure to the value upside from the project.



Refer to earlier in this report.


Minemakers holds 13.81% equity in UCL Resources Limited, worth approximately $2 million at the end of the Quarter.


Minemakers holds 4.65% of Australia Minerals & Mining Group Ltd worth approximately $0.4 million.

4. TNT MINES LIMITED (19% equity)

Minemakers was not supportive of TNT Mines' recent desire to consolidate its shares and is encouraging TNT Mines to seek a corporate solution to ensure its ongoing viability. Minemakers does not believe a potential ASX listing via IPO is realistic in the foreseeable future.



During the December Quarter 2012 Minemakers announced that Mr Andrew Drummond would retire as Executive Chairman and become Non-Executive Chairman of the Company effective 31 December 2012.

Founding Director, Mr Dennis Wilkins retired from the Board of the Company on 4 December 2012 and Mr Ian McCubbing joined the Board as Non-Executive Director on 21 December 2012.


At the end of the December 2012 Quarter Minemakers had cash of A$27.3 million. Refer to the December 2012 Quarterly Cashflow Report of today's date.
