North Dakota: land acquisition and drilling update

The Directors of Sirius Minerals Plc (AIM: SXX, OTC: SRUXY), the potash mining group, are pleased to announce that its wholly owned subsidiary, Dakota Salts LLC (Dakota Salts), has acquired a further 1,220 net mineral acres of lease areas adjacent to its existing properties in North Dakota.

The new acreage has been acquired from multiple unconnected owners for nominal initial cash payments per mineral acre with royalty payments due on mining production in line with industry norms. The Company now controls some 8,645 net mineral acres of lease areas overlying the Williston Basin, having an overall land position of approximately 19,847 gross mineral acres within North Dakota.

The Williston Basin currently accounts for approximately a third of global potash production.

Chris Catlow, Chairman of Sirius, commented:

We are pleased with the strong progress being made in North Dakota both in terms of our continuing land acquisition programme and our initial drilling activity. Coring of the Prairie Evaporate Formation at our first location is on schedule and expected to be completed within 18 days. The core samples will then be sent off for extensive laboratory tests.

Dakota Salts has deployed a Saxon rig in North Dakota which has a hook load of 400,000lbs and which is drilling to a planned depth of 8,600ft. Dakota Salts drilling partners on the project are North Rim Exploration Ltd (NREL) and Schlumberger Water Services USA Inc (Schlumberger).

Sirius Minerals continues to progress its projects in Queensland Australia and Western Australia.
