This statutory report to the Queensland Department of Mines and Energy is the annual activity report for Exploration Permit (Minerals) (EPM) 7721, the Nagoorin Oil Shale Deposit, Central Queensland, for the twelve-month period ending 21 March 2015. Holders of the EPM are Greenvale Mining NL, and Queensland Energy Resources Limited. 2. EPM 7721, granted in 1991, has most recently been renewed for a two-year term expiring on 21 March 2015. EPM 7721 provided the necessary underlying tenure to support the application dated 21st March 1996 for Mineral Development Licence 234 which was granted on 31 October 2012. 3. 2D seismic and CSG well data for the Nagoorin Graben has become available following the surrender of the Arrow Energy ATP 679. Preliminary interpretation of the data shows more detailed seismic reprocessing and reinterpretation together with CSG well interpretation is required within EPM 7721 for ongoing resource evaluation. 4. The annual review of parameters and assumptions underlying resource estimate for the oil shale resource discovered and delineated within the EPM and MDL was undertaken during the period. The figures for the estimate of the oil shale resources of the Nagoorin Deposit have been updated from those established in 2001 as a consequence of the evaluation of both seismic and CSG well information now publicly available. Based on grade cutoff limits of 50 litres per tonne at zero moisture (LT0M), and four-metre minimum thickness to a maximum depth of 502 metres below surface, the resource has been estimated as follows: Resource Tonnes Grade Moisture Shale Oil Category (millions) LT0M Wt% Mbarrels in-situ Measured 815 91 28.8 332 Indicated 1,585 92 27.4 665 Inferred 3,019 95 24.5 1,355 Total 5,419 93 26.0 2,351 Nagoorin EPM7721 Annual Report 2015 iv QER Pty Ltd 1. INTRODUCTION Exploration Permit Minerals (EPM) 7721 contains the Nagoorin Oil Shale Deposit. The deposit is located in the Boyne Valley, about 65 kilometres south of Gladstone (Figure 1). Investigations are conducted under a Joint Venture consisting of Greenvale Mining NL (GVL, 67%), and Queensland Energy Resources Limited (QER, 33%). Investigations in the tenement area led to the discovery and definition of the Nagoorin oil shale deposit. Subsequently an application for Mineral Development Licence 234 (MDL 234) was lodged to cover this deposit in 1996 and granted in 2012. While assessment by the Department of the MDL application was in progress, the underlying EPM tenure was maintained to support the application. This report is a summary of activities associated with the exploration and evaluation of the Nagoorin oil shale deposit, submitted as required under the terms of the EPM, in relation to the year ending 21 March 2015. During the period, the annual report for the previous term of EPM 7721 was submitted to the Department (Pope, 2014). 2. TENURE Exploration Permit (Minerals) 7721 EPM 7721 was granted on 22nd March 1991 over an area of 27 sub-blocks. The permit is a consolidation of former EPMs 4991 and 5889. The permit was renewed for three years commencing 22nd March 1993. The EPM was extended by subsequent renewals to 2015. The most recent application for renewal for 12 months (to 21 March 2017) was lodged on 22nd December 2014. As a consequence of grant of MDL 234, EPM 7721 was reduced to 14 sub-locks. Details of the tenement are listed below.

The application covers an area of 6,773 hectares. The outline of the area (MDL 234) relative to the EPM is shown in Figure 1.
