• Become lowest cost North American SOP producer

• Become first producer using Mannheim process in North America

• Acquired in 2015• 40,000 tpy of SOP • CDN$50 million capex• 30% after tax IRR• Proven process • Production targeted in H1

2018• Scalable• Potential for $14m in

average annual cash flows• NPV (after tax 10%) $82

million

• Original SOP project• 230,000 tpy of SOP• US $458 million capex• 20.1% after tax IRR• Lowest cost producer in

North America (US$ 172/ton)

• Major permits and water rights secured; infrastructure nearby

• Potential for US$100M in average annual cash flow

• NPV (after tax 10%) $482 million

Potassium Sulphate (SOP)

• Low-chloride fertilizer required for fruits, vegetables, nuts

• Domestic selling price 3x potash (“MOP”)

• Global consumption ~7 million tonnes per year (“tpy”)

• Demand potential is 10 million tpy• 400k t current production in North

America versus projected demand of 1M t demand

• One other North American producer

• Qualifies as “organic”

Potassium Sulphate (SOP)

Low chloride, high sulphur – providing benefits to crops not available with MOP

Global potential market demand of 10 million tpyCapacity growth limited in current North American

processUS$630/tonne in North America

Improves yield, taste, appearance and shelf life

Significant benefits for fruits, vegetables, nuts, tobacco
