Sirius Minerals (OTCMKTS:SRUXF) is a fertilizer development company focusing on the extraction and commercialization of polyhalite, a natural, multi-nutrient mineral used in crop nutrition. The company is advancing its flagship Woodsmith Mine project in North Yorkshire, England, which hosts one of the world’s largest known polyhalite deposits. Through an extensive system of underground tunnels and conveyor infrastructure, the development is designed to deliver high-purity fertilizer products to global agricultural markets.
Established in 2003, Sirius Minerals spent over a decade delineating the Woodsmith deposit and de-risking the project before its 2018 listing on the London Stock Exchange. Key project elements include twin production shafts extending more than 400 meters below surface and a 37-kilometer tunnel network to a processing and export facility on Teesside. International engineering firms are contracted to construct the infrastructure required to support large-scale, low-cost polyhalite production.
Polyhalite functions as a balanced source of potassium, magnesium, calcium, and sulfur, offering farmers a single-application, slow-release nutrient solution that supports soil health and enhances crop yields. The Woodsmith Mine is positioned to supply major agricultural regions across Europe, North and South America, Asia, and Australia, catering to growing demand for sustainable fertilizer alternatives.
Led by CEO Chris Fraser and supported by a board with extensive mining and agribusiness experience, Sirius Minerals is headquartered in London with operational offices near its project site in North Yorkshire. The company continues to advance engineering, permitting, and financing activities as it progresses toward the commencement of commercial production.
