Mulga Rock Deposits
Energy and Minerals Australia's (EMA) most advanced project is the Mulga Rock Deposits (‘MRD’) located within the larger Narnoo Project tenements, 250km east-northeast of the major mining centre of Kalgoorlie, and only 100km from the trans-national rail line. The MRD comprise three separate uranium bearing, polymetallic mineral deposits named Ambassador, Emperor and Shogun.
The MRD were discovered by the Japanese Government owned corporation, PNC Exploration Australia Pty Ltd ('PNC'), in 1979.
Positive Outcome of Scoping Study Nov 2010
In November 2010, the company announced a positive outcome to the scoping study that it had been conducting over the previous twelve months.

Coffey Mining JORC Compliant Resource Jan 2009 Mulga Rocks
In January 2009 Coffey Mining produced an initial JORC Code compliant Uranium Resource estimate for the MRD, using a database of available historical uranium chemical assays and equivalent grades from radiometric data compiled by EMA. The Resource estimate incorporates the results from 766 of 2,012 holes drilled prior to EMA acquiring the project.
Coffey Mining JORC Compliant Resource June 2010 Ambassador
In June 2010 Coffey Mining produced an updated JORC Code compliant Uranium Resource estimate for Ambassador, one of the three deposit that make up the MRD.

Development Path For MRD
Production is targeted for calendar year 2013.
Uranium
The MRD uranium and base metal mineralisation are some 5 metres thick and generally horizontal. The top surface is in the order of 38-55 metres below the surface.
Other mineralisation
Associated with the uranium mineralisation, or underlying it, are layers containing oily lignite (kerogens), oil, nickel and cobalt with possible credits of gold, vanadium, Rare Earth Elements ('REE') and other elements. The full extent of this mineralisation is presently not known.
PNC assayed samples from only 10 holes for elements other than uranium. All of these holes intersected nickel and cobalt values (and locally copper and zinc) in association with the uranium. This suggests that nickel and cobalt mineralisation may be wide spread within the Ambassador Deposit.
Drilling below Emperor has identified gold mineralisation some 75 metres below surface.
The MRD are hosted in lignite ('a young coal'). In addition there are large (totalling in excess of 500 million tonnes) lignite deposits (one below and adjacent to Emperor, the other 12 kilometres south of Emperor). These lignites contain kerogens (a precursor to hydrocarbons).
EMA intends to conduct geological and economic evaluation of the lignite, precious and base metals at the MRD.
