I refer to your letter of 13 March requiring further information regarding the proposal by Toro Energy Limited for an"Extension to the Wiluna Uranium Project" and our recent meeting with your assessment officers.It is our understanding that the following meets the request for further information:

• A table of Key Project Characteristics, consistent with the language of EAG I:• A map (including spatial data) identifying the development envelope for both Millipede and Lake Maitland

deposits: and• Identification on a map of the location of the baseline studies that have been submitted with the referral

documentation.

I attach the Key Project Characteristics table (Table I) and a map (Figure I) identifying the development envelope forthe proposed Extension to the Wiluna Uranium Project.

The development envelope for the proposal spans two uranium deposits and a connecting haul road between them asshown on the map (Figure I). The reports attached to the referral cover the following:

• Two terrestrial fauna surveys which covered the already approved development envelope for the Centipededeposit and the proposed development envelope for the Millipede deposit

• Flora and vegetation surveys which took in the adjoining approved Centipede development envelope but notthe proposed Millipede development envelope

• Three flora and vegetation surveys undertaken which covered the proposed Lake Maitland developmentenvelope with the exception of the haul road connection between Lake Maitland and the Millipededevelopment envelope

• Terrestrial fauna and fauna habitat surveys which covered the proposed Lake Maitland development envelopewith the exception of the haul road connection between Lake Maitland and the Millipede developmentenvelope

Further survey work is being undertaken which will be reported in the ESD and the PER.

If you have any further queries, please contact either Richard Yeeles or Alan Tandy on 9214 2100.
