Planning Approvals and Drilling Update


The Directors of Sirius Minerals Plc (AIM: SXX, OTCQX: SRUXY), the globally diversified potash development group, are pleased to announce the approval by the North York Moors National Park Authority of three additional planning applications for drill sites for the York Potash Project and to provide an update on drilling at SM2.


Planning Approvals


In a meeting held yesterday in Helmsley, North Yorkshire, the Members of the North York Moors National Park Planning Committee approved three further drill site applications following the Officers' positive recommendation.  The three sites are within commercial forestry blocks so will be largely out of view and will have a minimal impact on local communities.


SM2 Drilling Progress Update


Further to the update provided on 13 December 2011, drilling at SM2 (Howlett Hall) has now passed the latest fluid loss zone.  The hole is now 1,164m below surface and the rig is currently preparing to insert the last casing.  The cementing of the last casing is the final step before coring of the target zones commences.


By way of background, fluid loss zones are a relatively common feature of drilling into these geological sequences and were encountered in SM2 well above the potential mining horizons.  The remedies for this situation are to either pump down viscous materials which plug the gaps or the injection of cement to close them.  The cementing process requires the drill string to be removed, which adds to the overall drilling time.  Sirius encountered some such issues at SM1, but they did not give the same level of delays as experienced at SM2.


Chris Fraser, Managing Director and CEO of Sirius said:


"These additional sites will help us further define the extent of the world class resource that exists in the area.  We continue to progress the drilling phase as quickly as possible and while any delays are naturally frustrating they are a normal part of this style of drilling.  Importantly, they do not impact the potential or integrity of the deposit or the potential ease of mining."
