Ann: Annual Report 2018, page-4

Here's the bones of it:
Material uncertainty related to going concern
We draw attention to Note 4 in the financial report, which indicates that, excluding a one-off gain on the debt restructure, the Group incurred a loss after tax of US$140.3 million, and a net cash outflow from operations of US$44.8 million during the year ended 30 June 2018.
As a result of the Langer Heinrich Mine being placed into care and maintenance during the financial year it is expected that the Group will not generate any operating net cash inflows in the short term; therefore, the Group is dependent on raising new equity and/or a sufficient improvement in the uranium price to support the recommencement of operations. These conditions, along with other matters set forth in Note 4, indicate that a material uncertainty exists that may cast significant doubt on the Group’s ability to continue as a going concern.
Our opinion is not modified in respect of this matter.
