Heinrich Mine

A strategic tier one uranium asset with a long-life operation.

Our Langer Heinrich Mine in Namibia (75% Paladin ownership) is well on track to be a significant player in the decarbonisation economy of the near future. Uranium concentrate production and drumming was achieved on 30 March 2024. 

We have secured a strong uranium offtake portfolio within a rising market. At full production, the Langer Heinrich Mine’s annual uranium output is enough to supply over ten 1,000 Mwe nuclear power plants for a year.

The mine is located in central western Namibia approximately 80km east of Swakopmund and 85km northeast of the Walvis Bay major deepwater harbour. Modern infrastructure provides reliable and smooth access from the mine to the well-established port at Walvis Bay.

The deposit was discovered in 1973, and Paladin acquired Langer Heinrich Uranium (Pty) Ltd and its assets from Aztec Resources Ltd in August 2002.

An independent producer

Our Langer Heinrich Mine has already produced over 43 million pounds of U3O8 over a successful 10-year track record. The mine is projected to produce over 77 million pounds of U3Oin the future.

The uranium mined and processed at the Langer Heinrich Mine will be used to resource nuclear power plants, helping drive the global energy transition to a carbon-free, sustainable future.

Langer Heinrich Mine:

Namibia: a premier
uranium jurisdiction

  • Globally significant uranium province (Husab, Rössing and Langer Heinrich) and a major supplier of the world’s uranium
  • Uranium has been produced in Namibia since 1976 under a stable mining and uranium regulation regime
  • Excellent local infrastructure (port, road, rail, water & power) with proximity to the Walvis Bay industrial hub
  • Mining contributed ~10% to the country’s GDP in 20221
  • Strong community and government support for the uranium industry

History of Langer Heinrich Mine

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

The deposit is discovered after a government-sponsored airborne radiometric survey of the area.

General Mining Union Corporation Limited (Gencor) undertakes extensive evaluation work at the site from 1974-1980. Suspends work on the project in mid-80s following a fall in the prevailing uranium price.

Acclaim Uranium NL acquires the project from Glencor, completes a pre-feasibility study, and puts project on hold again due to prevailing uranium prices.

Paladin Energy acquires Langer Heinrich Uranium (Pty) Ltd in August and its assets from Aztec Resources Ltd (formally Acclaim Uranium NL).

Langer Heinrich commences production with a capacity of 2.7Mlbpa.

Construction of Stage 2 expansion to 3.7Mlbpa commences at the mine.

Langer Heinrich reaches Stage 2 design capacity in December.

Construction of Stage 3 expansion to 5.2Mlbpa commences early in the year.

Completion of Stage 3 expansion is achieved at the end of March.

The sale process for a 25% interest in the mine by CNNC is completed in July.

Process innovation focuses on the Bicarbonate Recovery Plant (BRP) which is commissioned in early March, resulting in significant reagent cost reductions.

With the continued decline in uranium prices, Langer Heinrich introduces a mining curtailment strategy in November.

Paladin places Langer Heinrich mine into care and maintenance in May due to sustained low uranium spot price. Mine successfully transitions to full C&M in August.

Paladin commences a Prefeasibility Study in February to further refine and verify the Langer Heinrich mine restart plan.

Paladin completes the Langer Heinrich Restart Plan, providing a clear pathway back to reliable production and re-engages with its long-term customers in an improving uranium market.

Paladin made the decision to return the Langer Heinrich Mine to production, supported by strong uranium market fundamentals and continued progress on marketing activities.

The Langer Heinrich Mine restart project progressed well during 2023, targeting first production in Q1 CY2024.

First production was achieved on 30 March 2024 at the Langer Heinrich Mine.
