Approvals update - Harbour Facilities

The Directors of Sirius Minerals Plc (AIM: SXX, OTCQX: SRUXY) ("Sirius" or the "Company") provide a procedural update on the approvals process for the proposed Harbour Facilities at Teesside for the York Potash Project ("the Project").

The Company has decided to withdraw its current application for a development consent order, with a view to refining certain options in the application. The purpose of the resubmission is to facilitate a more efficient examination process.

A revised application will be submitted in the near future and a brief update will be provided to the market when this is accepted by the Planning Inspectorate. This does not affect the overall timescales or the other key planning decisions for the Project.
