EXCHANGE RELEASE

WONARAH PHOSPHATE DEVELOPMENT MOU SIGNED WITH INDIA’S NMDC LIMITED1 June 2011

Minemakers Limited (ASX and TSX: MAK; NSX: MMS) has signed a non-binding, Memorandum of Understanding (“MOU”) with Bombay Stock Exchange listed NMDC Limited (BSE Symbol: NMDC; market capitalisation AU$21 Billion) to establish a pathway for the development of the Wonarah Phosphate deposit in the Northern Territory.

Under the MOU relevant NMDC management staff will join the Minemakers team to undertake a joint Feasibility Study into the agreed aspects of the full development of Wonarah, Australia’s largest known, undeveloped, phosphate deposit.

The proposed Wonarah development will include a mine and downstream processing facilities to produce beneficiated rock phosphate for export; phosphoric acid (an intermediate product); and finished fertiliser products such as DAP and MAP (Diammonium Phosphate and Monoammonium Phosphate).

The Feasibility Study is intended to be sufficiently advanced by early fourth quarter 2011 such that the results will support Minemakers and NMDC signing a full Joint Venture Agreement (“JVA”) governing the completion of bankable feasibility, financing and development of Wonarah and the downstream fertiliser manufacturing facilities.

The terms of the JVA will be negotiated during the advancement of the Feasibility Study, beginning shortly.

The general terms of the JVA are anticipated to include:

NMDC to acquire a 50% equity in the Wonarah Project.

NMDC will have responsibility for arranging project finance for the full development of

Wonarah, by way of debt finance.

Repayment by NMDC to Minemakers of certain project and other costs already incurred on the Wonarah project to date.
