- Sirius Minerals said it had entered into a design and build contract with subsidiaries of KGHM Polska Miedz, including DMC Mining Services, for the construction of four shafts required for its polyhalite project in North Yorkshire.

Sirius had been in extended discussions with AMC UK to finalise a shaft sinking contract, but decided to switch to DMC Mining instead.

'Due to protracted discussions with AMC regarding commercial arrangements Sirius engaged with DMC and other shaft sinking companies in parallel to consider alternatives,' Sirius said.

'Through this process, it has become clear that DMC, with their extensive and proven shaft sinking experience, are a strong construction partner for Sirius and will bring technical opportunities and a commercial partnership that can unlock potential savings in the construction schedule.'

'Sirius has therefore entered into a design and build contract with DMC and has terminated ongoing arrangements it had for the shafts with AMC.'
