Pan American is a Canadian company dedicated to providing fertilizer to growing global markets specifically in South and Central America. The company is focused on the extraction of a specific type of fertilizer called calcium sulphate (also referred to as “Agricultural Gypsum”) currently in Argentina. To ensure long term development and increase shareholder value, Pan American currently plans to significantly expand its current operational objectives while expanding its asset base by acquiring additional calcium sulphate and other fertilizer related assets and by expanding its markets to neighbouring countries with Argentina. When used as a fertilizer and as a soil remediator, calcium sulphate is a soft sulphate mineral composed of calcium sulphate dihydrate which is extremely rich in sulphur and calcium. When dissolved in water, the mineral becomes calcium and sulphate sulphur ions, both of which are required nutrients for plants. Calcium sulphate plays a vital role in establishing and maintaining good chemical balance in soil, water and plants, specifically with healthy root development. Ultimately, calcium sulphate increases overall crop quality and yields.
