Approvals update - Decision notices

The Directors of Sirius Minerals Plc (AIM: SXX, OTCQX: SRUXY) ("Sirius" or the "Company") provide an update on the approvals process for the York Potash Project ("the Project").

The Company has received the final Decision Notices formally granting planning permission for four out of five planning applications submitted by the Company to the local planning authorities. The Decision Notices are for:

· the mine and mineral transport system from Redcar and Cleveland Borough Council ("RCBC");

· the materials handling facility from RCBC;

· the temporary construction accommodation and a park and ride facility from Scarborough Borough Council, and;

· the operational park and ride facility (which sees an extension to an existing local park and ride) from the North York Moors National Park Authority ("NYMNPA").

The Decision Notice for the mine and mineral transport system planning application from the NYMNPA is currently on track to be received by the Company before the end of September 2015, as previously referenced in the 10 July 2015 announcement.

Chris Fraser, Managing Director and CEO of Sirius, comments:

"The Decision Notices represent the majority of the pieces of the planning jigsaw coming together. We thank the authorities concerned for their diligence and look forward to continuing to bring the York Potash Project to fruition."

As per the announcement of 22 April 2015, the proposed Development Consent Order for the Harbour Facilities at Teesside has been accepted for examination by the Planning Inspectorate. The preliminary hearing was held on 21 July 2015 and a final decision is due to be made by the Secretary of State for Transport no later than summer 2016. This is in line with Company expectations and this element of the Project is not on the critical path for construction.
