A strategic tier one mine in the global uranium industry with circa 5Mlbpa of uranium production capacity.

The Langer Heinrich Mine is located in the Namib Desert in Namibia, 80km east of the major seaport of Walvis Bay and about 40km south-east of the world’s longest running open pit uranium mine, Rössing uranium mine operated by Rio Tinto Group.

Paladin acquired Langer Heinrich Uranium (Pty) Ltd and its assets from Aztec Resources Ltd (formerly Acclaim Uranium NL) in August 2002. The purchase consideration was A$15,000 and a production royalty of 12 Australian cents per kilogram of yellowcake produced and sold.

CNNC Overseas Uranium Holding Limited, a wholly-owned subsidiary of China National Nuclear Corporation (CNNC), took a 25% stake in Langer Heinrich in July 2014.

Paladin placed LHM into care and maintenance in May 2018, however Paladin is currently undertaking optimisation and feasibility studies to prepare for a rapid restart once there is significant improvement in uranium market conditions.

Langer Heinrich is a surficial calcrete type uranium deposit containing a Mineral Resource of 123.4Mlb at a grade of 460ppm U3O8 across all resource categories.

Background

History of Langer Heinrich Mine (LHM)

Year Event
1973 The deposit was discovered in 1973 after a government-sponsored airborne radiometric survey of the area
1980 Between 1974 and 1980, General Mining Union Corporation Limited (Gencor) undertook extensive evaluation work at the site and suspended work on the project in the mid-1980s, following a fall in the prevailing uranium price
1998 Acclaim Uranium NL acquired the project from Glencor and completed a pre-feasibility study. The project was again put on hold due to prevailing uranium prices
2002 In August 2002, the Company acquired Langer Heinrich Uranium (Pty) Ltd and its assets from Aztec Resources Ltd (formally Acclaim Uranium NL). The purchase consideration was A$15,000 and a production royalty of A$0.12c per kilogram of uranium sold
2007 LHM commenced production in 2007 with a capacity of 2.7Mlbpa
2008 Construction of the Stage 2 expansion to 3.7Mlbpa commenced
2009 LHM reached the State 2 design capacity in December 2009
2012 Construction of the Stage 3 expansion to 5.2Mlbpa commenced at the beginning of 2010 and was competed on 31 March 2012
2014 On 23 July 2014 the sale process for a 25% interest in LHM to CNNC was completed
2015 Process innovation focused on the Bicarbonate Recovery Plant (BRP) which was commissioned in early March 2015 and resulted in significant reagent cost reductions
2016 Following the continued decline in uranium prices, LHM introduced a mining curtailment strategy in November 2016
2018 In May 2018 the Company placed LHM into care and maintenance (C&M) in May 2018 due to the sustained low uranium spot price and successfully transition the mine to full C&M in August 2018
2019 In February 2019 the Company commences a Prefeasibility Study in further refining and verifying LHM to restart plan
