Sirius Minerals Plc announced that it has entered into a design and build contract with DMC Mining Services UK Ltd. and DMC Mining Services Ltd, both subsidiaries of KGHM Polska Miedz SA for the construction of the four shafts required for its polyhalite project in North Yorkshire. Sirius has been in extended discussions with AMC UK Ltd. in respect of finalising the shaft sinking contract following the notice of award in July 2017 which anticipated execution of a finalised contract shortly afterwards. Due to protracted discussions with AMC regarding commercial arrangements Sirius engaged with DMC and other shaft sinking companies in parallel to consider alternatives. 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.
