SALE OF SOUTH PILBARA IRON TENEMENTS GOES UNCONDITIONAL

Sheffield Resources (“Sheffield”) (ASX:SFX) today announced it has received confirmation from Brockman Mining Limited (ASX:BCK, SEHK:159) that the sale of the South Pilbara Iron tenements is not subject to FIRB approval and is therefore unconditional.

Completion of the sale and payment of the upfront cash payment will now occur by 24 April 2013. As previously disclosed (see ASX release 2 April 2013), the material terms of the agreement are as follows:

• An upfront cash payment of $1 million;

• A supplementary cash payment of $0.10/tonne for all JORC compliant Mineral Resources (Measured, Indicated and Inferred categories) defined on any or all of the tenements, using a lower cut-off grade of 54% Fe. Sheffield has previously outlined an Exploration Target[1] of 20-60Mt @ 56-60% Fe (see ASX release 1 December 2011) on the sale tenements and identified further iron mineralisation as outlined in the ASX release dated 28 January 2013;

• A royalty of 1% FOB of all iron ore produced from the tenements. In addition, a price participation royalty of 5% would be applicable for all revenues received over $120/tonne FOB (CPI indexed) for iron ore sales from the tenements (i.e. an additional 4% on the amount by which the indexed FOB price exceeds $120/tonne); and

• Brockman to use best endeavours to complete a resource drill programme and resource estimate within 12 months and subsequent resource drill programmes as soon as practicable thereafter.

Sheffield Managing Director, Bruce McQuitty said the upfront cash payment of $1 million will increase Sheffield’s already strong cash position to approximately $7.2 million .

“In addition to current cash reserves and proceeds from the sale of the South Pilbara Iron tenements, we also expect to receive up to $3.37 million through the exercise of 16,873,332 ‘inthe-money’ options, each with an exercise price of 20 cents and expiry date of 30 June 2013.”

“These funds will be applied principally to advance the world class Thunderbird HMS and Red Bull nickel projects.”

There has been insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource.
