Share Purchase Plan Update

As previously announced the Company intends to accept $1,000,000 of applications under the SPP on a first received basis. These applications will be accepted in full.
Under the terms of the SPP the Company can amend the total amount of capital to be raised and extend the duration of the plan (subject to legal requirements). The Company will accept a further $2,000,000 at the Directors discretion bringing the total amount raised to $4,500,000. Applications over this amount will be returned to shareholders.
Due to overwhelming support and to give eligible shareholders more time to realise the benefits of any material developments during this period, the SPP will be extended one further week and will now close on June 7th 2016.
