Approvals update

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

In advance of the proposed special planning committee considering the Company's mine and mineral transport system planning application on 30 June 2015, the North York Moors National Park Authority ("the Authority") has published additional background reports on its website.

The reports form part of a number of review documents commissioned by the Authority to inform its assessment of the planning application. The findings of all the review documents will be taken into account in the planning officer's planning committee report, referred to in the 14 May 2015 announcement, which will be publicly available via the Authority's website at least five working days prior to the planning committee meeting.

As detailed when the application was submitted and announced on 30 September 2014, this is a normal part of the planning process so the Company is not offering further commentary on individual reports. Planning officers had already taken account of these and other reports when they advised of their likely open recommendation on the planning application (as detailed in the 14 May 2015 announcement).

The Company has also been in discussions with the Authority for a number of months about its proposed Section 106 Agreement ("Section 106") and it has now tabled an enhanced proposal. The revised Section 106 proposal, which will also be available on the Authority's website, is designed to address officers' concerns relating to the residual harm that can be addressed through Section 106 contributions.
