Paladin had available cash reserves of $40.5 million at the end of September, with about 18 months needed to bring the project back into production once a restart decision is made.
It will then take a further 15 months to reach full production.
Langer Heinrich is expected to yield 77.4 million pounds of uranium over a 17-year mine life, with cash costs put at $27.40/lb.
Peak annual production will be 5.9Mlb.
In line with the rising uranium price, Paladin said there had been an increase in market queries from utilities.
Meanwhile, Paladin is also looking at M&A opportunities and assessing the best way to progress other assets in its portfolio.
