Under the new agreement (the "Revised Agreement"), Sennen will have the right to
acquire a 70% interest in Monument by incurring further expenditures of US $4.5
Million by December 31, 2015.


Further, under the Revised Agreement, Sennen also has the right to acquire a
further 5.5% interest in Monument, for a total of 75.5%, by completing a
pre-feasibility study on Monument within 24 months of acquiring the initial 70%
interest. 


The share and cash consideration contemplated under the Original Agreement
remains the same in the Revised Agreement and, in this regard, the Company has
agreed to issue the final tranche of 20 million common shares (for a total
issuance of 50 common million shares) on or before December 20, 2013.


Ian Rozier, President and CEO of Sennen said: "Given our ongoing focus on
capital discipline and maximizing shareholder returns, we are delighted to have
agreed to a mutually beneficial revision of the option terms with our partners
at Paradox. The revised terms allow Sennen to reduce its capital commitments,
extend the earn-in time frame by a full year and substantially increase the
project interest to be earned. Based on work completed to date, we continue to
believe Monument to be an attractive potentially high grade potash project with
significant upside and look forward to advancing our technical suite in the
coming months."
