The document is an investor presentation for Potash Ridge Corporation outlining its two potash sulfate (SOP) fertilizer projects - Valleyfield in Quebec and Blawn Mountain in Utah. It notes that SOP demand exceeds supply in North America and these projects are strategically located to serve key crops. Valleyfield will be the first SOP producer on the east coast using a proven process. Blawn Mountain has 45+ years of reserves and will be the lowest cost producer in North America. The presentation highlights the projects, management team, and near term catalysts in an effort to secure financing and bring the projects online to capture opportunities in the growing North American SOP market.
