Having acquired the outstanding balance of Dakota Salts in 2009 the Company continued to increase its land position in Burke County in North Dakota. Following extensive geological studies during 2010 a drill site location was identified, based on the historical data available.

In August 2010 Dakota Salts was granted an Exploration Permit to drill a hole to a depth of over 2,700 metres and in November drilling commenced on the hole EBY-1. Drilling was carried out by Schlumberger Water Services USA Inc (SWS) and the Company’s North American geological consultants North Rim Exploration Limited (North Rim), with Saxon Energy Services as the drill contractor.

Following completion of the hole to a depth of 2,794 metres the core was analysed at the Saskatchewan Research Council laboratory. North Rim reviewed the results and determined that the hole had intersected 8.5 metres of the Esterhazy member from 2,702 metres with a weighted average K2O grade of 11.8% and 8.6% carnallite.

In light of the Company’s intense focus on the York Potash Project and the nature of the result of EBY-1, Sirius is continuing to consider its options on how best to add value for its shareholders from its investment in North Dakota. The Company believes the potash potential of the Prairie Evaporites in North Dakota remain a promising exploration target in the global search for potash.
