Annual statement of Reserves and Resources

Energy Resources of Australia Ltd (ERA) has completed its annual assessment and reconciliation of reserves and resources for both Ranger and Jabiluka. The results are set out on the attached page.

Ranger Reserves and Resources

The Ranger Ore Reserves and Mineral Resources are reported under the 2012 edition of the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves" (JORC 2012 code).

During 2018, the Proved and Probable Ore Reserves for Ranger decreased from 5,783 tonnes of uranium oxide to 3,735 tonnes of uranium oxide. This was primarily due to depletion by processing of primary and laterite ores and other reconciliation adjustments including favourable model variance.

In addition, there remains a volume of material available for processing that exceeds the time-constrained Ranger milling capacity. As the current Ranger Authority requires milling to cease by 8 January 2021, a defined quantity of material can be processed (regardless of the volume of ore available to be processed).

The final reserve total removes the least economic ore that will not be processed due to this constraint under the current mine plan (915 tonnes).

During the reporting period, all processed ore was sourced from either run of mine stocks or low grade stockpiles.

For the same period, Ranger Mineral Resources decreased from 55,135 tonnes to 54,701 tonnes of uranium oxide. This decrease of 434 tonnes was primarily due to removal of stocks below the reserve cut-off during the backfilling of Pit 1 in accordance with the mine closure plan, partially offset by the reclassification of material from Ore Reserves back to resource due to milling constraints.

The table below sets out the reconciliation of Ranger Ore Reserves:

Ore Reserves	Uranium Oxide (U3O8 tonnes)*
Ranger Ore Reserves as at 31 December 2017	5,783
Additions (favourable model variance)	1,148
Depletion by Processing	(2,280)
Exclusion of lowest grade ore not mined or processed by 8 January 2021	(915)
Ranger Ore Reserves as at 31 December 2018	3,735

*Rounding differences may occur

The 2018 Mineral Resource statement for Jabiluka remains unchanged at 137,107 tonnes of uranium oxide.

Competent persons

As required by the Australian Securities Exchange, the above tables also contain details of other mineralisation that has a reasonable prospect of being economically extracted in the future but which is not yet classified as Proven or Probable Reserves. This material is defined as Mineral Resources under the 2012 edition of the "Australasian

Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves" (JORC 2012 code). Estimates of such material are based largely on geological information with only preliminary consideration of mining, economic and other factors.

While in the judgment of the Competent Person there are realistic expectations that all or part of the Mineral Resources will eventually become Proven or Probable Reserves, there is no guarantee that this will occur as the result depends on further technical and economic studies and prevailing economic conditions in the future.

The information in this announcement that relates to Ranger and Jabiluka Ore Reserves and Mineral Resources is based on information compiled by geologist Stephen Pevely (a full time employee of ERA). Stephen Pevely is a member of the Australasian Institute of Mining & Metallurgy and has sufficient experience which is relevant to the style of mineralisation and the type of deposit under consideration and to the activity being undertaken to qualify as a Competent Person as defined in the JORC 2012 code.

Stephen Pevely consents to the inclusion in this announcement of the matters based on their information in the form and context in which it appears.
