Notes regarding Contingent and Prospective resource estimates 1. The estimated quantities of petroleum that may potentially be recovered by the application of a future development project(s) relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further exploration appraisal and evaluation is required to determine the existence of a significant quantity of potentially moveable hydrocarbons. 2. The information that relates to Prospective Resources for Melbana is based on, and fairly represents, information and supporting documentation compiled by Peter Stickland, a director of Melbana. Mr Stickland B.Sc. (Hons) has over 30 years of relevant experience, is a member of the European Association of Geoscientists & Engineers and the Petroleum and Exploration Society of Australia, and consents to the publication of the resource assessments contained herein.
