About ERA

The former Ranger uranium mine lies within the 79 square kilometre Ranger Project Area, which is located eight kilometres east of Jabiru and 260 kilometres east of Darwin. ERA ceased mining operations in 2012 and continued to process stockpiled ore until 8 January 2021, when the Ranger Authority required processing to cease. The sale of the last drum of uranium oxide was made in May 2022. The Ranger Project Area is now being progressively rehabilitated. Under the Ranger Authority, ERA must rehabilitate the Ranger Project Area to establish an environment similar to the adjacent areas of Kakadu National Park. If this occurs and it is the opinion of the Minister, with the advice of the Australian Government’s Office of the Supervising Scientist (OSS) (previously referred to as the Supervising Scientist Branch), the rehabilitated area could be incorporated into the Kakadu National Park, if this aligns with the Traditional Owners wishes. ERA’s ongoing rehabilitation activities on the Ranger Project Area are undertaken according to an authorisation granted under section 41 of the Atomic Energy Act 1953 (the Ranger Authority). Under the terms of the current Ranger Authority, ERA’s rights to access, occupy and use the Ranger Project Area continue until 8 January 2026. As this Act was amended in November 2022, ERA is working with the Australian Government, Northern Land Council (NLC) and Gundjeihmi Aboriginal Corporation (GAC) – on behalf of the Mirarr Traditional Owners, to negotiate a new Ranger Authority that allows rehabilitation works to continue past 8 January 2

ERA holds the title to the world-class Jabiluka Mineral Lease. In accordance with the Jabiluka Long Term Care and Maintenance Agreement, the Jabiluka deposit will not be developed by ERA without approval of the Mirarr Traditional Owners. The Jabiluka estimated Mineral Resource is 137,100 tonnes of uranium oxide at a cut-off grade of 0.2% U3 O8 . The current lease is due to expire in August 2024. ERA has commenced discussions with stakeholders, including the GAC, concerning any application for renewal of the Lease. ERA’s strategic priority is to rehabilitate the Ranger Project Area and the company’s primary focus is to create a positive legacy and achieve world-class, sustainable rehabilitation of former mine assets. The principles that guide ERA’s approach are safety, teamwork, respect, integrity, and excellence in every area of the business. The company’s shares are publicly held and traded on the Australian Securities Exchange. Rio Tinto, a diversified resources group, currently holds 86.3% of ERA shares.
