13 Move to Downstream ProcessingThe merchant rock phosphate concentrate market is shrinking as more rock producers vertically integrate and value-add on site. Downstream products like SPA are expected to be more sought after by end users compared with rock concentrate. Morocco (OCP) Exports 2005 Global Rock Phosphate Concentrate Market Morocco (OCP) Exports 2012 Source: 2005 data from IFA, Production and Trade Statistics: 2012 data from FMB monthly report Phosphates, February OCP (Office Cherifien des Phosphates) is owned by the Government of Morocco. Morocco’s concentrate exports were 13.4 million tonnes in 2005 and approximately 9.5 million tonnes in 2012. Source: IFA, US Geological Survey, FMB. Merchant market share, which is world exports as a percentage of world production, declined from 22% in 1999 to 13% in For 2012, Morocco’s exports were approximately 9.5 million tonnes, or 35% of total world exports of 27 million tonnes.

16 JDCPhosphate - FloridaJDCP’s demonstration plant is due to be commissioned in 1H CY2013. This is expected to be the defining process in the commercialisation of IHP. JDCP is a Florida-based private developer of the IHP technology which aims to dramatically improve the efficiency of the production of superphosphoric acid from rock phosphate Minemakers has the exclusive Australian licence to use IHP for SPA production and Wonarah’s large size ore characteristics are particularly well suited to IHP JDCP has been developing IHP for several years. A pilot plant has confirmed the process and JDCP is scheduled to commission a 12,000 short tpa P2O5 demonstration plant in Florida in 1H CY13. This is expected to be the defining process in the commercialisation of IHP JDCP investors include Minemakers, Vulcan, Mitsui & Co. (USA) Inc, Florida Opportunity Fund and Espirito Santo Ventures (Portugal) If successfully proven, IHP is expected to result in substantial benefits: Significant capital and operating efficiencies Produces high value ±70% P2O5 SPA for premium fluid/high nutrient fertiliser Modular (each kiln designed to produce 181,000 metric tpa contained P2O5) Low environmental impact, co-product has value Logistical cost concentrated on high value product

17 Wonarah Production OptionsThe Improved Hard Process (IHP) delivers a ±70% P2O5 Superphosphoric acid product (SPA) at a lower capital and operating cost and much improved environmental impact.

20 Indicative Wonarah EconomicsAt current prices and subject to successful validation of IHP technology, indicative internal Minemakers estimates show robust NPV & IRR outcomes and comfortable operating margin. Each IHP kiln is designed to produce 259,000 metric tonnes SPA (±70% P2O5) or 181,000 metric tonnes1 of contained P2O5 and is expected to cost US$150M – 200M per kiln Target production is based on 5 installed kilns, but there is flexibility to adopt an incremental expansion approach to enable operating cashflows from early kilns to contribute to the funding of each additional kiln An incremental build approach is a lower risk development approach and has the potential to significantly reduce external funding requirements. For example, if 1 kiln is added each year for 5 years this is expected to halve external funding requirements compared with construction of 5 kilns immediately Kiln expansion can be accelerated if conditions warrant 1. Note that JDCP quote each kiln production as 200,000 short tons of contained P2O5. 1 short ton is equivalent to 0.91 metric tonnes.

21 Strategic Partnership with Vulcan PhosphateVulcan has a deep understanding of world fertiliser markets and a strong fertiliser investment track record. The investment in Minemakers is a strong endorsement of the potential at Wonarah to create a significant high value phosphate production facility. On 2 April 2013 Minemakers announced that Vulcan had made a strategic investment in Minemakers: A placement of 14m shares at A$0.18 (33% premium to prevailing share price) A 4 year option to acquire a further 14m shares at A$0.30 Following the placement, Vulcan holds 5.7% of Minemakers Vulcan is an investment vehicle jointly associated with two sophisticated, long term fertiliser market investors, Agrifos and Solvochem The Agrifos group of companies is owned by Farouk Chaouni, Timothy Cotton and Margaret Smith. Following the sale of its Pasadena, Texas ammonium sulfate plant to Rentech Nitrogen in November , for a cash price of US$138 million and other consideration, the Agrifos group remains focused on project and business development activities in the fertiliser and related sectors Solvochem supplies chemicals, solvents and plastics worldwide through it’s network of companies located throughout Europe, the Middle East and Africa. Solvochem is an acknowledged authority in the field of bulk storage and distribution of chemicals and petrochemicals Vulcan has deep fertiliser market knowledge and relationships; particularly with potential offtake partners. Vulcan is also a major shareholder in JDCP Further enabling relationships are being explored together with Vulcan

22 Wonarah Indicative Development TimetableThe BFS strategy is to ensure that significant expenditures are deferred until further certainty is obtained on IHP. Finalisation of the BFS will occur post that point.

23 Investment Thesis RecapMinemakers provides a pure exposure to a commodity of strategic importance at an attractive current valuation. Investment in irreplaceable commodity of strategic importance Phosphate is an irreplaceable commodity Vital for ensuring long term food production security Strategic location in a politically stable environment providing favourable access to end-markets Wonarah is a world class asset with an existing infrastructure solution Minemakers owns 100% of Wonarah Minemakers has access to IHP, a potentially game changing patented kiln technology to produce high grade SPA at Wonarah Producing high value SPA reduces the sensitivity to transport and logistical costs Incremental kiln development options significantly reduces reliance on third party finance and provides development flexibility Significant cash-backing and support of sophisticated phosphate investor Minemakers has strong cash backing of approximately A$27m post Vulcan placement Investment by Vulcan at a premium to market price is confirmation of project potential Plan to complete BFS in 1Q CY2014 subject to IHP validation

24 Phosphate Facts

25 Phosphate – Crucial for Food ProductionWith no substitute for phosphate and 40% of world food production directly linked to manufactured fertiliser application, phosphate is crucial. World Fertiliser Consumption 40% of world food production is directly linked to manufactured fertiliser application Phosphate fertilisers facilitate Root development Water use efficiency Early plant maturity Higher yields No substitute for phosphate N Nitrogen Essential to formation of protein Protein makes up most of the tissues in living things Manufactured from gas or coal (ammonia, urea) P Phosphorus (Phosphate) Critical to plant development Key to photosynthesis, converting sunlight to energy Important to respiration, cell division and growth, energy storage and transfer in cells Phosphate is mined, usually from surface K Potassium (Potash) Produces higher quality crops More weight per kernel, greater food oil production, better wheat food qualities Important in carbohydrate and starch synthesis Potash is mined, usually underground

26 Importance of Fertiliser in Food SupplyAs the world availability of arable land decreases, crop yields will become an increasing focus resulting in a heavy reliance on fertilisers. Crop Yield and Fertiliser Usage in India Fertiliser consumption (mt) Consumption (mt) Arable Land per Capita Worldwide arable land per capita is expected to fall from 1.15 acres to 0.53 acres by 2039 Source: Food and Agriculture Organization, United Nations

27 A MINED PRODUCT, ESSENTIAL FOR MANKINDUses of Phosphate Phosphate has wide reaching uses in addition to fertilisers including steel manufacturing and toothpaste – it is essential for mankind. A MINED PRODUCT, ESSENTIAL FOR MANKIND 10% 90% Elemental Phosphorus Herbicides and pesticides Matches Phosphors Food supplements & additives Glass & china making Steel manufacture Laundry detergents Toothpaste & baking Rust inhibitors Fertilisers for Food Fertilisers for animal feeds Fertilisers for fibre crops Fertilisers for biofuel crops

28 Global Supply of PhosphateThe Middle East and North Africa have most of the worlds reserves with Morocco controlling 36% of the merchant market. Wonarah represents a politically stable, alternate source of supply. Seven countries in Middle East and North Africa account for: 79% of world reserves 27% of world production 75% of world merchant market Morocco has 36% of the merchant market “Phosphate is vital for all forms of life and given its irreplaceable role in sustainable global food supply, it is of paramount importance to establish supply sources in regions where long term political risk is demonstrably low”

29 Proximity to Emerging Agricultural MarketsIn 2005, 18 countries accounted for 75% of arable land in use in developing countries (~966mha, or ~60% of the World total arable land in use)1. Wonarah’s planned export port (Darwin) is well positioned to supply the 2 largest developing agricultural markets in the world as well as several other significant Asian markets 1. Developing countries using more than 10M ha of arable land. Source: Looking ahead in world food and agriculture: Perspectives to 2050, Food and Agriculture Organization, United Nations.
