Table of Mineral Resources Estimates (Updated 30th June 2010)
All data is rounded and discrepancies in summation may occur.
The Table of Mineral Resources Estimates which is updated to 30 June 2010, takes into account resources which have been
diminished only through tenement swaps and sales since April 2009 including the ?Zeta tenement?(287,516oz) and the ?Eta-
No Mistake?(36,225oz) tenement. The estimates are based on the statement of Mineral Resources for the Brightstar Gold
Project in April 2009.
The information that relates to Mineral Resources for the Brightstar Gold Project is based on A1 Minerals Statement of Mineral
Resources for the Brightstar Gold Project (April 2009) which is based on the information compiled by Mr Anthony Ryall who
is an independent consulting geologist and a member of the Australasian Institute of Mining and Metallurgy and has sufficient
experience relevant to the style of mineralisation and type of deposit under consideration and to the activity undertaken to
qualify as a Competent Person as defined in the JORC Code (2004). Mr Ryall has provided Competent Person sign-off for the
quality and representativity of the drill hole data, geological interpretations, resource estimation procedures and results.

PLEASE NOTE: These are probable reserve estimates. Also the Group has recently undergone the transition from explorer to miner and geological as well as
metallurgical understanding and databases is subsequently significantly increasing the knowledge and understanding of the deposits which may result in changes
to these estimates. Other factors which may change current estimates are changing extraction factors and techniques; metallurgical factors; ore reconciliations
through the plant as well as changing economic conditions. Depletion of ore reserves through mining during 2010 has not been taken into account. The
information that relates to Ore Reserve Estimates for the Brightstar Gold Project is based on information compiled by Mr John Williams who was an employee of
A1 Minerals Limited and is a member of the Australasian Institute of Mining and Metallurgy and has sufficient experience relevant to the type of deposit and mining
methods under consideration and to the activity undertaken to qualify as a Competent Person as defined in the JORC Code (2004).
